BBC botches grade school CO2 science experiment on live TV – with indepedent lab results to prove it

WUWT readers may recall this story from November 3rd NOAA deletes an “inconvenient” kids science web page where NOAA took down a web page called “It’s a gas, man” that talked about a tabletop science demonstration that kids could do themselves to “prove” that CO2 retains more heat. Problem was, the experiment as presented then was flawed, and when it received some attention from skeptical websites, NOAA recognized the flaw and took it down, replacing it later with an updated page.

Fast forward past Climategate to this past Thursday Dec 17th, and we find that the BBC decides to try essentially the same experiment on live TV for an impressed and non questioning audience.

Only one problem, the BBC presenters botched the experiment. Fortunately we can show why, because WUWT reader  Professor Kevin Kilty of the University of Wyoming, who took an interest in recreating this experiment with students in his physics class well before the BBC did their experiment, has conclusively demonstrated its scientific shortcomings in an experiment log he sent me on December 20th showing results of a November 23rd experiment run.

What got me connecting what Professor Kilty had done to the BBC live TV experiment was a comment from WUWT reader Bryan C of the UK. Here’s an excerpt:

Dear Anthony

Here’s something I found shocking and that you don’t see every day: the British government’s former chief scientific adviser Professor Sir David King flagrantly lying on national television to boost the dubious idea that some foreign agency (the Russian secret service?) was behind Climategate.

http://news.bbc.co.uk/2/hi/programmes/newsnight/8418356.stm

This was in the context of BBC 2’s Newsnight staging a peculiar experiment, with a politically-correct black female “space scientist” heating two bottles – one containing “air” (last time I looked, that included carbon dioxide anyway) and one containing “atmospheric air with a greater concentration of carbon dioxide” (they didn’t say how much they were adding, of course, but I’d bet it was substantially more than 0.000388%!). Surprise, surprise — the latter bottle grew hotter… Of course it did. A greater amount of carbon dioxide will be warmer when heat is applied. This is not a surprise! The proportions are key, of course, as you know.

Newsnight itself characterised the effort right at the start as a “very unscientific experiment” — so why do it at all?! In fact the “science” as presented was misleading and selective to the point of deception.

Indeed when you watch the BBC video, it is clear that there’s no sort of control of any kind, the thermocouples were placed haphazardly at different angles into the bottles, and there’s likely alignment differences between the lights illuminating the bottles. It seems so from my viewing of the video.

Professor Kilty also viewed the BBC video and writes:

You can see that the two bottles start at temperatures of 32+ C. Perhaps the house is this warm, we don’t keep ours this warm, but more likely they have run the experiment and know pretty well in advance how it will turn out. I tried to see from the size of the spot on the bottle if one or other is obviously closer to the lamp–I can’t– but what really matters is the thermocouple, of course. The NOAA description in “its a gas, man” looks like the epitome of careful research in comparison.

This is just kid science. The BBC did their best. Not as good as the ten-year old of a couple of weeks ago, though. It is funny that the journalist sells this as “proof” of global warming early in the sequence.

Here is what a properly conducted experiment looks like, as performed under professor Kilty’s supervision by students at his lab at the University of Wyoming.

A SILLY EXPERIMENT ABOUT CO2
KEVIN KILTY

Date: December 20, 2009.

Figure 1. Two separate set-ups running at the same time. While it looks like our lab is bathed in mood- lighting this is an illusion. The extremely bright filaments fooled my automatic camera. The room was brightly lit. The nearest set-up uses Moll-type thermopiles, while the distant setup is more like the NOAA description, except with thermocouples replacing lab thermometers.

Are there endless silly or meaningless experiments and demonstrations that one can do with carbon dioxide (CO2)? We’ve seen a few on WUWT recently.1 On Tuesday November 3, 2009,WUWT exposed one endorsed by a major scientific organization under the headline NOAA deletes an inconvenient kids science web page.

Indeed, all reference to this page appears now gone at NOAA. But, thanks to the efforts of WUWT, and the help of the way-back machine,2 selected physics students in three of my courses at LCCC got to try the experiment as someone at NOAA designed it. As it turns out, this experiment is silly for what it attempted to show, but it provides darned good lessons about scientific experiments.

The first group of physics students to get a crack at greenhouse warming in a two liter bottle were from my Physics 1050 course – physics without math. They set the experiment up as closely to the NOAA specifications as possible and made Runs 1 and 2 as I describe below. The algebra based physics course got a stab at it next, then the calculus-based physics class had their try. These classes modified the experiment to get a better picture of what was going on. They performed Runs 3 and 4, respectively.


1. Procedure

The NOAA web-page suggested doing the experiment according to the following recipe.
(1) Partially fill both bottles with water. In fact, we filled each with the same amount of water – about two inches worth.
(2) Add the seltzer tablets to one of the bottles. We delayed this step until we had the apparatus assembled.
(3) Suspend the thermometers inside the bottles in such a way that you can measure the temperature of the air and seal the tops with molding clay. We thought there was little reason for sealing the top completely, so we used a cork stopper with hole large enough to allow gas generated in the bottle to pass out around the thermometer.
(4) Place the lamp at equal distance between each bottle. This is the tricky step in this seemingly simple experiment.
(5) After an hour, measure the temperature of the water in each bottle. We thought the word “water” was a mistake here because there was no instruction to make the amount of water in each bottle equal, nor any reason the water would be of interest when the thermometers were suspended in air. Accordingly we monitored the temperature of the air to equilibrium at least, which was less than an hour.
Despite the simplicity of the procedures, we encountered plenty of experiment design issues. These included:

1) the typical lab thermometers have fiducial marks at one-degree interval and so temperature can be read to a resolution of about 0.5◦C at best,3

2) the marks are actually not of uniform size,

3) it is really difficult to get a label completely off a two-liter soda bottle, and so there is a readily available shield or
reflector to confound one’s results. Finally, there is that deceptively simple step 4; Place the lamp at equal distance between each bottle.

Figure 2. Thermocouple in a two-liter bottle. Note that the thermocouples are not perfectly vertical, nor are they likely to be perfectly centered. The near thermocouple points away from the lamp and residue from the label shields the thermocouple.

Although a person can purchase clear light bulbs that allow one to see precisely where the filament is, and what geometry it has, there is almost no way to decide what is the exact center of radiation. After all 95% of the radiation leaving the lamp is infrared and invisible. From outside the lamp does radiation appear to come from the filament? Or does the bulb envelope appear as the source? Moreover, even if a person can decide where is the center of radiation, there are a host of other ways to get the set-up wrong. Figures 2 and 3 show some. Students rarely noticed if the thermometer was centered and vertical or if it stayed that way during the course of the experiment – and as one might expect to happen sometimes, thermometers in the CO2-filled bottle tipped toward the lamp, as Figure 3 shows, while those in the control bottle tipped away like Figure 2.

Figure 3. A thermocouple in a two-liter bottle. Note that this thermocouple points toward the lamp, and has a reflector from the residue of the label torn from the bottle.

2. Results

The table below summarizes our research of November 23, 2009. The first experimental run, using ordinary lab thermometers, appeared to detect an increased temperature rise in the CO2-filled bottle. However, students failed to appreciate at this point that repeating this experiment, no matter how exactly, could arrive at a different outcome.

Indeed, Run 2, using six thermocouples read to a temperature resolution of only 1◦C indicated no average difference in temperature rise, but showed greatest temperature change in some bottles without CO2.

Run 3, using thermocouples read to better resolution of 0.1◦C, showed the greater average temperature rise to occur in the non-CO2 bottles. In this case students swapped thermocouples among bottles to make certain no variation was the result of mis-manufacturing of these sensors. We concluded from these results that sufficient replications of properly randomized runs would likely show no detectable difference at temperature resolution typical of equipment in K-14 science labs.

Run 4 made use of Moll-type thermopiles. These devices capture a very broad spectrum of radiation, from far IR through visible, and conveys it to a highly absorptive collector at the base of a conical reflector. A series connection of 17 type-K thermocouples indicates the temperature rise of the absorber. These thermopiles have a sensitivity of 0.28mV/μW; a voltage that good quality bench multimeters can read easily. Figure 4 shows one of these devices.

Figure 4. A Moll-type thermopile. Picture from Cenco on-line catalog.

In these runs we organized a moll-type thermopile to look at the lamp through our plastic bottles. When the potential of the thermopile became stable we then dropped two selzer tablets in the bottle and monitored the decline in potential until it became stable again. In this manner we managed to avoid all confounding influences except variations in one plastic bottle to another, and possibly extremely small variations in aim of the thermopile. The average decline was 0.095mV .
This translates into a typical decline of 0.34 μW of radiation power entering the conical collector.

3. Discussion

The presence of CO2 in a plastic bottle reduced radiation collected by a thermopile looking through that bottle. But what radiation is reduced, and what causes the reduction? We are pretty sure that visible light isn’t reduced as there is no visible difference between bottles with CO2 and those without. Thus, the difference is likely in the infrared (IR) part of the spectrum. CO2, as we have heard interminably for the past 25 years, absorbs certain bands of IR radiation, most notably in the IR near 2, 3 and 4 micrometers wavelength, and in longwave bands between 13 to 17 micrometers wavelength. At thermal equilibrium CO2 will radiate in these same wavelength bands as much power as it absorbs. The radiated radiation does not travel in the same direction as the absorbed radiation was traveling, however. It is radiated uniformly in all directions. In the case of our experiment this leads to a small decrease in power reaching the Moll-type thermopile.

Applying this to the case of a simple Earth atmosphere, containing nothing but CO2 and having no weather, leads one to conclude that longwave radiation leaving the top of Earth’s atmosphere will decline in magnitude slightly. This decrease in longwave power traveling away from the surface forces the Earth’s surface temperature to rise slightly in order to maintain its thermal equilibrium. This is the “greenhouse effect” in its pure form.

Table 1. Various runs of our experiment. Thermometers run showed the expected enhanced ΔT of the CO2- filled bottle. First run with thermocouples, though, showed no average difference, but was fraught with con- founding influences. Temperatures were displayed at the whole number resolution because of the digital readout. Run 3 thermocouples read with a digital display having 0.1◦C resolution and showed the largest effect in bottle with no CO2. Thermopiles were read with a bench DMM having 10 μV resolution.

4. Conclusions

When this experiment is set-up according to the prescription on the NOAA webpage it is quite possible to get a difference of temperature of 1 ◦C between or among thermometers even if none of them contain any CO2. A properly randomized experiment will likely result in no discernible difference among thermometer readings irrespective of CO2 in bottle or not. The issue is one of not enough magnitude of effect to resolve on typical lab thermometers.

An instrument as sensitive as a Moll-type thermopile can detect a small difference in radiation passing through bottles filled with CO2 as compared to an identical bottle not filled. The amount of IR power re- directed by a two-liter, CO2-filled bottle appears to be about 100μW/m2.

The most important result of this experiment is how it shows students so many issues of experiment design. First, there is the issue of how difficult temperature measurements are to make accurately. Students are quite surprised at this. They are equally surprised that seemingly identical temperature sensors will not measure identically. Second, there is also the difficulty of proving conclusively that A causes B when the experiment includes confounding factors. This is an important lesson about the value of skepticism in climate change research, observations, and publicity. If X, Y, and Z cause B just as readily as does A, then what allows one to claim A causes B?

Back to the BBC video, Bryan C points out some problems with statements by Professor King, who joined the group after the CO2 bottle experiment was performed. Here is his comment, continued.


Professor King adroitly avoided key questions. Anyone there with any knowledge of the science could have taken him apart. The BBC clearly wasn’t interested in finding anyone equipped with the facts who could have countered the orthodoxy. In contrast, we had an ignoramus who expressed scepticism at the beginning saying he was now completely convinced. Others taking part who maintained their scepticism unfortunately didn’t have the facts at their fingertips to back up their positions.

Professor King’s assertions about Climategate (from 6:20) were particularly shocking. He conceded that the behaviour shown was unacceptable, but no conclusions were then drawn by him — the program simply moved on! But I was most stunned by his obfuscatory introduction of the conspiracy theory about “agencies” which went unchallenged, and involved a direct fabrication about mobile phone conversations.

“Remember that these emails go back to 1998 and they’ve been accumulating them and just released them in the week before Copenhagen…

“Let me also make this allegation for the first time in public. It’s an extraordinarily sophisticated piece of work to hack into all of these emails and mobile phone conversations, right? What agencies have got the sophistication to manage that? I leave you to think about that.”

Of course, the most likely scenario is not of an outside hacker but a whistleblower inside the CRU who pulled them together and released them. The suggestion of “an extraordinarily sophisticated piece of work” doesn’t really hold up if you’re just referring to emails, but introducing the idea of monitoring mobile phone conversations (a complete lie as far as I’m aware) serves to boost the conspiracy theory and muddy the waters. And this man was Britain’s most senior scientist?

I hope you can draw people’s attention to this deception!

Regards Bryan C

Clearly there has never been any mention of “mobile phone conversations” in any known discussion about the Climategate incident. This appears to be a complete fabrication by Professor King. It is troubling that the BBC has not corrected this.

All in all, this was not a well thought out or well researched video presentation by the BBC, and in my opinion it does a disservice to the citizens that pay taxes through television licenses to support the BBC.

UK readers are encouraged to make the issues and independent experimental results known to the BBC and to media monitors there.

  1. From your article:

    Dear Anthony

    Here’s something I found shocking and that you don’t see every day: the British government’s former chief scientific adviser Professor Sir David King flagrantly lying on national television to boost the dubious idea that some foreign agency (the Russian secret service?) was behind Climategate.

    I believe I now know whom the Russians were addressing in this comment:

    They have gathered evidence about how and where the operation was carried out, although they are not prepared to say at this stage who they think was responsible.

    A Russian intelligence source claimed the FSB had new information which could cast light on who was behind the elaborate operation.

    ‘We are not prepared to release details, but we might if the false claims about the FSB’s involvement do not stop,’ he said. ‘The emails were uploaded to the Tomsk server but we are sure this was done from outside Russia.”

    http://www.dailymail.co.uk/news/article-1235395/SPECIAL-INVESTIGATION-Climate-change-emails-row-deepens–Russians-admit-DID-send-them.html

    Not for sure, but it will take some convincing to tell me that we are talking about two different things. CRU was a leak, not a hack. They are waiting for everyone to forget. I will now finish reading the article. :-)

  2. Probably not quite OT, but the Team and their relatives say that the recent gradual temperature decrease in the stratosphere evidences that the anthropogenic CO2 is warming the troposphere.

    Anyone in the know please teach me the truth.

  3. Mobile phone conversations? Are any of the emails text messages? That is all I could think of. No difference as to content anyway, but weird that he would know that if they were. Still standing by my thoughts about the Russians above. It is a leak from inside CRU and the Russians are arm-twisting the UK to keep it a secret. Wonder how this played out at Copenhagen? No mention of Russia in the news, was there?

  4. I watched that video when it was on live and was shocked when I saw it. The presenter, a long time global warming alamist – his career in the Beeb has had its sails full to bursting with CO2 since he started on Newsnight – kept saying the words “scientific experiment” over and over again. Not all were convinced in the audience but his comments at the end about it being “good” to pursuade people of this “science” is telling.

    BTW – Clive Saran, editor of Computer Weekly, was put onto the BBC Today Programme (Radio 4 morning news show) and pretty much debunked Professor King’s assertions of the Russians stealing the emails. He called the claims “rather far fetched” but you can just about detect him trying not to giggle. He didn’t go with the leak theory. I wonder if he was told not to.

    Mr Saran’s interview is here : http://news.bbc.co.uk/today/hi/today/newsid_8419000/8419818.stm – scroll down to the 8:45 slot.

  5. tokyoboy (00:38:13) :

    The team is ignoring the fact that the decline in solar activity has cooled the stratosphere. They know this, but are ignoring it. Sad, really. Anyhow, when activity picks up head over to RC and ask them if the stratosphere is still cooling.

  6. Thank you for posting the article.

    I watched the original programme with mounting incredulity at what I was watching. It was basic chicanery but it was enough to fool the assembled audience.

    Personally, I have given up complaining to the BBC: like the Pope, the BBC believes itself to be infallible on doctrinal beliefs such as global warming.

    As regards local press: my own UK local paper now refuses to print letters which mention climategate or anything associated with it. I have had four letters on the topic rejected.

    It makes you despair.

    REPLY: Despair I understand, submission I do not. – Anthony

  7. he he.

    The mobile phone red herring story now what that has to do with Klein Bottles filled subantially with CO2 I do not understand.

    As I understand CO2 in the earth life system. CO2 represents more strongly in the saline solutions of the earth life system. Far more so, I would consider the experiment upside down and I would consider and experiment measuring real life at geo progressive understanding getting the water solution wrong but then again I am not a chemist. I would use water at geo saline levels and I would use that proportion in my Klein bottle, in a multidimensional effect system. But I am not a chemist, just a pirate.

    And I had some beer.

  8. What was the PPM of CO2 in the one bottle as opposed to the other? Also, pressure increases temperature. Was the pressure in the 2 bottles kept constant? I’d bet not.

  9. I always thought climate science was complex. BBC has now persuaded me that increasing CO2 levels makes climate simpler and totally predictable.

  10. I too have given up complaining to the BBC – no point! However, you can always send the journalists an email. Just put a dot in between their first and second names, end it with @bbc.co.uk

    I have done this a number of times and had replies – even though their email addresses aren’t shown anywhere.

    OT. The CET is surely no longer credible, if it ever was http://hadobs.metoffice.com/hadcet/cet_info_mean.html Current England average temp is supposed to be 3.9C. We’ve had 10 days of below zero temps here with overnight temps of well below zero, yet the average is supposed to be 3.9C! Can’t see it myself and have asked for clarification from the Met Office. The CET was down until two days ago due to “software problems” and the bottom right hand corner of the site shows a box of data which hasn’t been working correctly for over a year! I’ve given up moaning to them about it.

  11. At 175 C (the lowest temp at which I readily found common data)

    1) The specific heat of air is 1.02 kJ/kg-K.

    2) The specific heat of CO2 is 0.71 kJ/kg-K.

    Hence, for a given heat input, the temperature rise in CO2 would be greater than that in air.

    I would attribute any observed increase in temperature to heat conducted to the gas from the container. This heat flux would cause a higher temperature increase in CO2 than air.

  12. Experiments like this are silly for many reasons. Most importantly they don’t reflect the natural system. Everyone knows that CO2 absorbs radiation in a few very narrow bands of wavelengths. Any moisture in the air would greatly defeat this, though, and swamp the impact of CO2. Unless they filled the control with dry nitrogen, any difference should be practically immeasurable.

    Any water in the bottles will fill the bottles with water vapor and swamp the water vapor will greatly swamp the impact of the CO2. If you look at this graph you see the top line showing where CO2 is more opaque to IR radiation. The lower line shows an atmosphere of 5x more H2O than CO2. The H2O accounts for the vast majority of the absorption and the CO2 produces just a couple of little bumps on the graph.

    Having any water whatsoever in those bottles would result in the CO2 impact being nearly completely masked by the water.

    Secondly, in the atmosphere there are a couple of different things going on that don’t go on in the bottles. First is convection. When a molecule of CO2 absorbs a photon, it will rise. At some point it will emit that photon in some unknown direction but there is a 50% chance it will be emitted away from the ground. Also, CO2 absorbs radiation from two sources. It absorbs heat radiation from the ground but it also absorbs solar radiation. The majority of the Sun’s energy reaches Earth as infrared. Greenhouse gasses will act to block some of that infrared from reaching the ground. A molecule that absorbs a photon from the sun has a 50% chance of re-radiating that photon back toward the ground so you can say that greenhouse gasses also block the same percentage coming in from the Sun that they block coming up from the ground.

    So greenhouse gasses would act to somewhat moderate daytime high temperatures and nighttime low temperatures. The average temperature might rise but the greatest impact is on raising nighttime low temperatures. They act to reduce daytime high temperatures somewhat.

    The most significant impact would be felt at the poles during winter when a great increase in CO2 would act to reduce radiation into space over some selective wavelengths represented by the dips in the above graph and somewhat moderate winter low temperatures. Lets say for argument’s sake that this increase in winter low temperatures increases the annual average by 5 degrees. That does not mean that the summertime temperature is 5 degrees warmer and more snow/ice melts. It means the annual average went up but mostly by increasing winter temperatures. Say the temperature in winter rose from -60F to -50F. The net result is probably no change in ice coverage and an increase in penguin populations though decreased mortality due to hypothermia.

    But the important thing is that those bottles are not 50 miles tall and there is no convection within them. If an molecule absorbs a photon, rises some distances and releases it, it releases it above more CO2 where it has a greater chance of being re-absorbed on its way to the ground and less of a chance of re-absorption on its way into space. So convection acts to make it harder for heat to come down than to go up. The atmosphere naturally wants to move heat out into space. The bottle can’t do that as efficiently because the temperature difference between the bottom and the top of the bottle is not much.

    But back to the diagram. Putting any water in the bottle blew the experiment up. There should have been no measurable difference in temperature with the apparatus used in the experiment as water vapor and the plastic itself would have dominated the CO2.

  13. How can the air temperature be dropping?.

    The first look we get at the temperature readings, the normal air reading was 35.6c and the co2 was 34.0c. You see them change to air 35.5c and co2 34.7c. Last reading is air 34.6c and co2 38.7.

    It also appears to me the co2 lamp is slightly lower relative to the bottle.

  14. The temperature of the air bottle started at 35.6C,
    after roughly 10 minutes of heating was COOLER, at 34.6C

    There’s a lesson.

  15. Also notice the water droplets on the inside of the bottle in figure 3. That says the atmosphere inside the bottle is saturated with water vapor and it is condensing on the inside of the bottle.

  16. This strikes me as classic dog and pony show grandstanding designed to sway the feeble masses to where they were before being skeptical, one that is done in sheer desperation and one that is done too late in the game to have any sway but onto the most feeble. The idea being that an observer sees “regular people” being convinced by this chicanery and then doubts themselves. Unfortunately, due to what increasingly appears to be a ubiquitous ignorance of all things rooted in science and reality in today’s society, this sort of kitchen style demonstration seems to be the most complicated things that folks can understand.

    By the way, with reference to an earlier post on WUWT regarding the coincidence of the last date of the emails in the climategate novella to the closing date of the FOIA, I wonder why people are still making wild statements about the “hack” and now some supreme data gathering force? It would seem obvious at this point that the university itself assembled these emails in response to the FOIA in case it were forced to comply with the law, and this file was either left on a public server or released internally…

  17. The bit I like in Kevin Kilty’s essay is the one in the conclusions about A causing B and how difficult this can be to show in an experiment, even if you seem to get a result. During my PhD, when a seemingly good result was found, this sentimient was shortened into the versatile phrase

    “Was it plugged in?”

  18. In this ‘experiment’, the thermocouple was the target, right? (Like the earth floating in the big Utopian sky (in one bottle) and in a hellish soup of man-made CO2, flatulent, etc… (in the other)???

    Did glaciers and ice-caps form in either bottle? (just curious…)
    …How about spontaineous polar bear materializations, or deaths?

    To quote Huey Lewis & the News: “Sometimes bad is bad.”

  19. I understand pressure arguments. But my thinking is Ocean temperature, as I understand it Infared and other raditaions do not heat the lower oceans I may be wrong as a Pirate.

    But my reading, not Saline but plain H2 o. You decrease the temperature the more CO2 is held. Pressure and Temp and CO2 may be symbiotic or correlated

    My coke bottle experiment(not beer bottle) is simple.

    Let’s see what happens as we apply heat to a Carbonated water. The results are outstanding with coke, depressing with beer.

    Note, Australian Children are not to experiment with carbonated drinks from Bloke and Shiela fridges.

    Stern wag of finger at accidental Aussie kids in this high brow place.

  20. This is a huge scoop! Who knew there were mobile phone conversations hacked? Only the FSB or the CSIS could/would do that! Which was it? Were they working together? The world needs to know! Why was such huge news slipped out like that? Did Sir David reveal this by mistake? Does he know too much? Is his life now in danger? Ian Fleming, eat your heart out – real life is much more exciting than your mundane stories!

  21. I’m glad this is getting attention.

    I’d posted about that program just after it was broadcast, as I was amazed by the allegations about “agencies” and “mobile phones”. Another WUWT reader replied to tell me he’d also just watched it and that King had said no such thing.

    It seems different people can hear and see different things, eh?

  22. My problem is specifications.

    The earth life system is a gas moisture system under gravitiational effect.

    For the life of me I dont understand why, all gas elements are not measured in the biggest heaviest (by mass) elements of the system are not measured.

    I will piss off now.

    I can understand measuring CO2 at Mauna Loa if the game is fraud not science.

    Just thinking out loud on Xmas eve in Oz.

    Selective measurement stations may prove a political or monetary point but that is hardly science.

    If the argument is CO2 why is measurement so selective and only in the air or gas.

    On topic of Xmas Eve, Mr Watts and Moderators, I have never encountered a better run or free blog.

    I was there when blogs run free. Desk top publishing and commmunities of interest.

    My Bandana and eye patch is off with respect. Nice to see science back.

  23. Tiny typo: “indepedent” for independent in the headline (discovered when forwarding the URL and headline to colleagues who fumed at the farce when it was broadcast).

    Thanks

  24. I remember well the BBC Newsnight experiment.

    What annoyed me at the time was not the crass nature of the experiment, sadly that’s what I’ve come to expect from the BBC. It was the implication that anyone sceptical of any of the aspects of AGW is un-scientific. As though all the ‘Science’ is on their side of the argument.

    I thought it was extremely condescending towards its audience.

  25. Perhaps one of the reasons that the BBC does these dumb experiments is because more and more of the educated middle class British are emigrating. Here in Australia we are inundated with them. Our gain and Britains loss. Everytime I speak with an emigre, they are over the moon that they have left Britain (‘Escaped’ as one couple put it). When the middle class start deserting then the end is in sight.

  26. The BBC is an official sock puppet for Global Warming, as I’m sure you know. I complained to the BBC about a weatherman on Radio 5 Live spouting pro warming propaganda before a weather bulletin unchallenged. The response I got gave me proof that they are pro warmist:

    ‘Below is an excerpt from the section of the report relating to coverage of the climate change debate:

    “The BBC has held a high-level seminar with some of the best scientific experts, and has come to the view that the weight of evidence no longer justifies equal space being given to the opponents of the consensus. But these dissenters (or even sceptics) will still be heard, as they should, because it is not the BBC’s role to close down this debate. Acceptance of a basic scientific consensus only sharpens the need for hawk-eyed scrutiny of the arguments surrounding both causation and solution.”

    The full report can be found on the BBC Trust website:

    Our view is that the BBC covered this story at length and that we did so in a fair and impartial manner. We will continue to report on the climate change debate in this way, allowing appropriate airtime to both those who support the broad scientific consensus on the causes of climate change and to those who reject it.’

    The first sentence quoted from the report says it all and it’s worth repeating: ‘The BBC has held a high-level seminar with some of the best scientific experts, and has come to the view that the weight of evidence no longer justifies equal space being given to the opponents of the consensus. ‘

  27. I saw the Newsnight piece when transmitted and was pretty disgusted at the time. If my calculations are correct one litre of air contains perphaps 0.25ml carbon dioxide (250ppm). A reasonable comparison would have been to inject an extra 125ul to represent man-made CO2 emissions to date and compare the differences in temperature. And you can bet there would have been no discernable difference. Simply filling the bottle with 100% CO2 was misleading to the extreme.

  28. Messing this experiment up as bad as she did gives entirely new meaning to “it ain’t rocket science”.

  29. I love these simplified experiments. As a non-scientist I would have asked

    “Why is Mars sometimes as cold as −140 °C despite 95% of its atmosphere being composed of Co2? Where is the runaway warming?”

    I know there are other factors to be considered in any warming of a planet’s atmosphere but it would force them to bring out the other factors thus making their experiment appear meaningless. ;-)

  30. Reader Brian C.’s letter states:
    “one containing ‘atmospheric air with a greater concentration of carbon dioxide’ (they didn’t say how much they were adding, of course, but I’d bet it was substantially more than 0.000388%!).
    Current atmospheric CO2 content is 388 ppmv, which is 0.0388%, not 0.000388%.

  31. I complained to the Beeb about it – from the view it was an attempt to fool less educated viewers that the ‘science was settled’ and was therefore propganda and needed apologising for. I got one reply trying to fob me off, which I rejected saying they have not answered the main question I raised, that the experiment was tosh and asked them ‘do you stand by this experiments validity’. So far no reply….i’ll chase it up after Xmas with a link to this article. Can I ask any other uk viewers to do the same.
    The point is, this is an example of something tangible that the beeb got totally wrong and used to editorialise…thats not thier remit. They are on very shaky ground here and if pressed hard enough will have to admit they misled the public.

  32. That BBC article was little more than propaganda.

    Which is what we expect from the BBC.

    But as other commentators have said the cheif scientific advisor is something else. He is desperate to smear the Russians.

    I think this shows how rattled they are.

  33. To Anthony and all who contribute to this site, many thanks for this and the other exposures of the past year, may 2010 bring more progress in overturning the global warming charade.

    Please allow me to ask forgiveness for ordinary people who are inundated by the relentless propaganda of the mass media and its directing agent, government. They are formidable antagonists, even for those like me who try to understand what is a complex subject. It is hardly surprising so many are confused.

  34. Just repeat the experiment with the bottle positions reversed (and repeat the pairs of expreriments several times, if necessary). The the effect of the lamp centre of radiation being difficult to source is removed.

  35. As a non scientist, I make it you will need 24.4 cubic litres of CO2 at standard temperature and pressure to have one mole of pure CO2 gas to work with.
    Starting with that you could calculate energy absorbed over time.

    I really cannot see how using 2 litre plastic bottles with any level of air/CO2 mixture will give valid results. How much IR does the plastic absorb? It is a closed environment experiment, simply not valid for the open atmosphere.

  36. The nonsense and irrelevance of this experiment is as evident as can be: CO2 traps infrared light and has no absorbance in visible light. In fact this experiment would evidence that short wave infrared from the solar radiation is absorbed in the top layer of the atmosphere and never makes it to the earth. If at all, the experiment should be performed in the dark and in the cold e.g. 15 degrees Celcius to have any relevance. Besides, there is not a point of discussion that CO2 absorbs certain bands of infrared, both from the solar spectrum and from the earth surface and atmosphere radiation and there is no excuse not to set up a valid experiment even if this involves more effort. Shame on the media to confuse the public by producing and publishing more nonsense.

  37. Fasool Rasmin (02:25:20) :

    “Perhaps one of the reasons that the BBC does these dumb experiments is because more and more of the educated middle class British are emigrating. Here in Australia we are inundated with them.”

    If you think there are no educated middle class people left in Britain you should follow this blog:

    http://www.bbc.co.uk/bbctrust/our_work/other/century21.shtml

    It’s just the BBC that are ‘dumbing down.’

  38. This would be the Dr. King who was Chief Scientist to the UK government. Here he is in action:

    “Andrei Illarionov, former chief science adviser to President Putin:
    … in respect to the presentation made by representatives of the so-called official team of the British government and the official British climate science, or at least how they introduced themselves at the seminar. I personally was surprised by the exceptionally poor content of the papers presented…
    Simultaneously, they revealed an absolute—and I stress, absolute inability to answer questions concerning the alleged professional activities of the authors of these papers. Not only the ten questions that were published nine months ago, but not a single question asked during this two-day seminar by participants in the seminar, both Russian and foreign, were answered.
    When it became clear that they could not provide a substantive answer to a question, three devices were used… The British participants insisted on introducing censorship during the holding of this seminar. The chief science adviser to the British government, Mr. King, demanded in the form of an ultimatum at the beginning of yesterday that the program of the seminar be changed and he presented an ultimatum demanding that about two-third of the participants not be given the floor.The participants in the seminar who had been invited by the Russian Academy of Sciences, they have been invited by the president of the Academy of Sciences Yuri Sergeyevich Osipov. Mr. King spoke about “undesirable” scientists and undesirable participants in the seminar. He declared that if the old program is preserved, he would not take part in the seminar and walk out taking along with him all the other British participants.
    He has prepared his own program which he proposed, it is available here and my colleagues can simply distribute Mr. King’s hand-written program to change the program prepared by the Russian Academy of Sciences and sent out in advance to all the participants in the seminar.
    A comparison of the real program prepared by the Academy of Science and the program proposed as an ultimatum by Mr. King will give us an idea of what scientists, from the viewpoint of the chief scientific adviser to the British government, are undesirable. In the course of negotiations on this issue Mr. King said that he had contacted the British Foreign Secretary Mr. Straw who was in Moscow at the time and with the office of the British Prime Minister, Blair, so that the corresponding executives in Britain should contact the corresponding officials in Russia to bring pressure on the Russian Academy of Sciences and the President of the Russian Academy of Sciences to change the seminar’s program.When the attempt to introduce censorship at the Russian Academy of Sciences failed, other attempts were made to disrupt the seminar. At least four times during the course of the seminar ugly scenes were staged that prevented the seminar from proceeding normally. As a result we lost at least four hours of working time in order to try to solve these problems.
    During these events Mr. King cited his conversations with the office of the British Prime Minister and had got clearance for such actions.
    And thirdly, when the more or less normal work of the seminar was restored and when the opportunity for discussion presented itself, when questions on professional topics were asked, and being unable to answer these questions, Mr. King and other members of the delegation, turned to flight, as happened this morning when Mr. King, in an unprecedented incident, cut short his answer to a question in mid sentence realizing that he was unable to answer it and left the seminar room. It is not for us to give an assessment to what happened, but in our opinion the reputation of British science, the reputation of the British government and the reputation of the title “Sir” has sustained heavy damage.

  39. Years ago the BBC 7pm news n views prog decided to demonstrate that bathwater flows clockwise around the plug hole. They rigged up a bath in the studio, addd enough water, and pulled out the plug. Nothing happened: the British plumbing industry hadn’t yet been taken over by Polish plumbers, and the drain pipe was blocked. Plus ca change plus la meme chose…..

  40. Please could someone enlighten me or am I just plain dumb?
    I assume that the thermal conductivity of a gas is its ability to absorb heat energy.
    Thermal conductivity of Oxygen =0.024 (W/mK)
    Nitrogen=0.024 (W/mK)
    Carbon Dioxide=0.0146(W/mK)
    Methane=0.03(W/mK)
    Air = 0.024(W/mK) as you would expect as Atmospere is approx. 96% Oxygen/Nitrogen.
    Therefore would an increase in Carbon Dioxide in the Atmosphere or Bell Jar
    (not really comparable) not reduce the Thermal conductivity albeit by an infinitesmal amount and therefore absorb less heat.
    Am I being to simplistic?

  41. There is a weekly slot on BBC called Newswatch, where a journalist invites BBC bureauweenies on to answer viewers’ complaints/comments. The answer always takes the form of the Tony Blair defence: “we did nothing wrong, we did what we thought was the right thing to do, and in any case we will never admit that the complaint/comment has any merit”. It really is a waste of time trying to engage with the BBC.

    If you really want to get the blood shooting out of your eyes please spend a few minutes on the the BBC Editorial Guidelines web page:

    http://www.bbc.co.uk/guidelines/editorialguidelines/edguide/accuracy/misleadingaudie.shtml.

    A particularly good section is “Misleading audiences”.

  42. Re: Dave F (00:39:49) :
    It is a leak from inside CRU and the Russians are arm-twisting the UK to keep it a secret.

    I read that differently and Russia/FSB is threatening to release more information if people don’t stop blaming them. They’ve probably done their own checks on the server in Russia that got used as the file drop and may have obtained info from the proxies used to put it there. Proxies aren’t always anonymous and the FSB may have access to information that Western agencies don’t.

    So I urge people to keep blaming the Russians because our own investigation seems to be going slowly, or quietly.

    As for txt messages, King is just showing how little he understands of the science involved, or how much effort would be needed for a leaker to have dropped the files.

  43. Just had a thought –

    Why would anyone want to keep some large plastic bottles and a number of ultra-violet lamps around their house?

    Some party eh?

  44. I saw this indoctrination on the BBC.
    BBC is now in panic mode, ClimateGate was a no event in Copenhagen.
    This event was apparently taken put together recently, because when I saw it the camera looked outside the window and one could see heavy snowflakes.
    The irony of that made it even more comical.

    Yes, CO2 is a greenhouse gas, which anybody can read about in physics books. Apparently we will fry because of that.
    In come an authority figure, David King and talk down to us.
    The new way to prove something, in this case CAGW is to use authority.
    Repetition and proclamation from authority figures was a techniqe the nazis was good at too.

  45. ” The extremely bright filaments fooled my automatic camera. The room was brightly lit.’

    The effect in the photo, however, is beautiful! It reminds one of the light effects produced by the Dutch painters of the 17th c,. Rembrandt, Vermeer, etc.

  46. Sorry to bang on about it but here is the link to the BBC Trust (sic) June 2007 document FROM SEESAW TO WAGON WHEEL Safeguarding impartiality in the 21st century

    http://www.bbc.co.uk/bbctrust/assets/files/pdf/review_report_research/impartiality_21century/report.pdf

    Look on page 40 where will be found the background to the BBC’s decision to bias its reporting on man-made climate change: “The BBC has held a high-level seminar with some of the best scientific experts, and has come to the view that the weight of evidence no longer justifies equal space being given to the opponents of the consensus.”

    My FOI request to know who were “the best scientific experts” on climate change has been rejected. The only conclusion to be drawn is that the BBC wishes to conceal the names of its “best experts”.

    I am following this up. See: http://www.whatdotheyknow.com/request/request_list_of_scientific_exper

    Merry Christmas!

  47. For your information, I have made an official complaint to the BBC about this travesty. There were almost 130 complaints on the Newsnight web page, all echoing the sentiments explained in the above article. Not surprisingly I have not heard from the BBC yet, but I hope Justin Rowlatt ( Ethical Man) is picking up his P45. To endure a whole month of greenie programmes from the BBC, only for realpolitik to blast it all out of the water in Copenhagen was rather ironic. The BBC seems to be run by media studies graduates of a certain political persuasion and have turned a once great programme into the propagandist arm of the WWF.

  48. All the BBC kitchen setup did was demonstrate that CO2 is a “Green House” gas. We already know that CO2 is a “Green House” gas. So what was the point?

    The BBC kitchen demonstration says nothing about how much an increase in CO2 will raise the temperature of the Earth. Indeed, that is the entire debate, and it wasn’t touched on in the least little bit.

  49. tokyoboy (00:38:13) :
    Probably not quite OT, but the Team and their relatives say that the recent gradual temperature decrease in the stratosphere evidences that the anthropogenic CO2 is warming the troposphere.

    So, they’re claiming that warm air no longer rises — because of AGW, it now *sinks*…

  50. In the video the temperature of the bottle without the CO2 actually dropped after turning on the lamp. This proves to me the experiment was a fake. Is there a law that can be used to have the perpetrators of this fraud charged with something?

  51. I reviewed the video a few times. I’m almost convinced the whole episode was staged. The main reason is I don’t believe so many people can be so stupid not to notice the drop in temperature in the bottle without the CO2 and question it.

  52. I just saw the video and the experiment… Is this what the science -and for that matter BBC too- look like these days? Are we really this blind? Is this what we call now “education”?
    Because if it is, I’m freaking out !! ;]

    ps that man has no pride; mr King is no king in fact, he’s just an ignorant professor.

  53. Trefor Jones (03:51:49),

    The BBC has an “Ethical Man”?? That’s really very funny. Is it a parody? Does he wear a clown suit? Or is he really that insufferable?

    If I went to work for the BBC, could I be “Superior Man”? “Wonderful Man”? “Totally Honest Man”? “The Pope’s Supervisor”?

    Do BBC employees get to pick whatever title they want, no matter how silly?

  54. Well, as we can see, all we need is a simple bottle test to prove AGW and that the climate system’s feedback effects are completely well-known and very simple. (sarcasm)

    Therefore it is reasonable to suggest that all funding for climate science should be cut immediately. So no more CRU, no more GISS, no more Met Office supercomputers, no more NOOA, etc.

  55. Should the thermocouple not be shaded from the lamps – to prevent radiant energy simply creating an increase in temperature in the thermocouple itself (and not the gasses). Stevenson Screens are shaded, so surely the thermocouple should be.

    .

  56. Assuming that Dr David King is still affiliated to a university or similar institution why don’t you report him formally for academic misconduct? You should also report the producer and presenters of ‘Newsnight’ to the Director-General and the BBC Trust for professional misconduct.

    These things happen unchallenged because there is a lot of complaining on websites but no actual action taken.

  57. I think the s@@@ will the fan when Briffa decides to spill the beans. I think he was the mole (although I maybe 100% wrong). At this stage we should be concerned for his health and safety….You can be sure that the powers to be will be putting enormous pressure on the mole at this time.

  58. “mikef2

    ….I got one reply trying to fob me off…. ”

    I didn’t even get a reply to fob me off and I pay my licence fee. I complained about bias of the experiment which was reported to prove the science of global warming. They made no mention of the contentious parts of global warming science eg clouds, convection, latent heat of evaporation, etc etc etc etc.

    A back of an envelope thought I had as the temperature in the BBC experiment was approx 4 deg C higher in the CO2 bottle. Double CO2 = 1 deg C increase so thay must have added 2^4 = 16 times atmospheric content and as anthropic CO2 is about 1/3rd of atmosphere thay added in the order of 3×16=48
    times the total CO2 caused by man since the start of the industrial revolution.

    I’m sure I’m right if they are right ( ;>)

  59. Ecotretas (01:25:42) :

    They might also try to explain all these hundreds of deaths that are ocurring because of the cold: http://ecotretas.blogspot.com/2009/12/december-2009-cold-death-toll.html
    199 and counting. If you know of more, please let me know.

    It is usually only the direct deaths (man found in car..) that make the news. Obviously estimates vary but here in the UK they tend to fall into the same ball park.

    “For every 1 degree fall in the winter average air temperature, there is an approximate one fifth increase in excess winter deaths – 8,000 deaths nationally.”

    Just google “excess winter deaths inurl:.ppt” or similar (you may have to add “UK” to that if you are elsewhere)

    You can be sure that the numbers rise in direct proportion to fuel prices and carbon hysteria. Statistics eh.

    Oddly enough such items are still available at the BBC – with actual numbers.
    (search “excess winter deaths” from the BBC main page for many, many more)

  60. How about repeating the experiment using glass flasks? Decent labware flasks will presumably be more uniform than plastic coke bottles and won’t have sticky labels on them. (A good way to remove the sticky residue is smear peanut butter over it, then let it sit over night.)

    How about adding a know volume of water to each flask?

    How about measuring pressure in each bottle, and correcting for it if there’s a difference? PV=nRT

    Heck, for that matter, why not use two empty flasks, then fill one with CO2 from a tank? Fill a third one with helium or some other gas, and see what happens.

  61. Can anyone explain why the temperature dropped 1C in the bottle without the CO2 pumped into it? If there is no explanation, this point alone proves this experiment was either a fake or badly done. Either way the BBC must be made to apologies.

  62. A careful examination of the Newsnight video shows that it was not simply botched, but was intentionally rigged to deceive the viewer.

    Full details are given in my comments 72 and 79 of the relevant page of the’Ethical Man’ blog – see
    http://www.bbc.co.uk/blogs/ethicalman/2009/12/in_praise_of_scepticism.html#comments

    It is clear that video from multiple ‘takes’ of the experiment were cobbled together to produce the final result as used in the broadcast.

    As this intentionally misrepresented the facts of what really occurred, it is a breach of the editorial guidelines for news on the BBC, in particular the section on Accuracy – Staging & re-staging events. See
    http://www.bbc.co.uk/guidelines/editorialguidelines/edguide/accuracy/stagingandresta.shtml

    This raises serious questions about the integrity of the ‘Ethical Man’, the ‘top British scientist’ and the editors of the programme.

    The issues around climate science are inherently complex – misrepresenting science and misleading viewers is extremely unhelpful to better public understanding.

  63. pfff they’ve demonstrated something the skeptics admit exists – elevated co2 absorbs more IR and warms the air around it.

    So what’s the contention? Just a bunch of silly nitpicking.

  64. I also complained to the BBC about this demonstration. This is an extract –

    ****
    Any increase in temperature observed is due to the fact that the thermal conductivity of the bottle containing CO2 is approximately one half of that containing of air (nitrogen + oxygen).

    Thermal conductivity is a property that determines how much heat per time unit and temperature difference flows in a medium. Since, at equilibrium, the heat flow out of the CO2 bottle is impeded, when compared with the bottle containing air, this will cause its temperature to settle at a higher value.

    I find it extraordinary that you should make the claim that this in any way explains ‘man-made global warming’ for the following reasons –

    1) The concentration in the CO2 bottle is ~ 100% vs. .038% in the atmosphere.

    2) You have demonstrated a thermal conductivity effect not a radiative one which is what the so-called ‘Greenhouse Effect’ is supposed to be.

    3) The source of heat is inside the bottles and heat is being conducted away into the outside atmosphere whereas in the so-called ‘Greenhouse Effect’ the sun is the source of heat and heat is being radiated towards the earth’s surface.

    4) If there is any radiative heating of the CO2 bottle it has no relevance to the so-called atmospheric ‘Greenhouse Effect’ in which heat is supposed to pass from the (cooler) atmosphere to the (warmer) earth’s surface. In fact we know from the ‘Second Law of Thermodynamics’ that this is impossible. …

    ****

    So far I’ve had no reply.

  65. Jerry (04:26:44)

    Wouldn’t the infrared absorption of glass be a problem if glass bottles were used? But then how do polytunnels work if the conventional explantion for a glass greenhouse is correct? Oh no, were we told lies at school? (Probably to get us ready for life)

  66. I wonder if the humidity increased due to the water/bakingsoda/vinegar reaction.

    crosspatch (01:25:30), window panes of the popular sealed unit variety are a maximum of 12 mm aprt, so convection currents do not increase the rate of heat transfer.

    John M Reynolds

  67. Just to remind non UK residents that the BBC is a state funded organisation.
    If you have a television or any device able to receive a BBC transmission (including a computer) You by law have to have a TV licence. About $200pa.
    Even if,like me,you don’t watch the BBC you still have to have a licence.
    A fine of $1500 or imprisonment if you are found not to have one.
    I believe in freedom of speech and do not begrudge the Aljazeera station its right to exist.
    I don’t have to watch it and I certainly don’t have to pay for it.
    Taxpayer funded propaganda and indoctrination in the traditions of ‘Pravda’ are what I am paying for. By law.

  68. Well if I were to attempt this experiment, I would set it so that I can flush both bottles alternatingly with both gas mixtures, while they are being illuminated. That should reduce experimental error.

  69. They are using seltzer tablets dropped into water to create the CO2.

    Was there any attempt to account for what the fizzing tablet did to the water vapor inside the “CO2” bottle? I would expect it to have a much higher amount of water vapor compared to the non-CO2 bottle.

  70. “Current atmospheric CO2 content is 388 ppmv, which is 0.0388%, not 0.000388%.”

    ??? Surely the latter number is correct. 0.0388 would be 388 parts per 10,000 –two orders of magnitude difference!

  71. I’ve written a post on this madness before – relating to a similar experiment by the Royal Society of Chemistry.

    http://buythetruth.wordpress.com/2008/12/08/greenhouse-nonsense

    It also shows how incredibly ignorant are those who write about the ‘greenhouse effect’. The RSC actually states “Because they act in a similar way to the glass panes of a greenhouse (ie letting in more light radiation from the Sun than they let infrared radiation out), they have been nicknamed ‘greenhouse gases’”, which is of course complete bunkum; and the Hadley Centre for Climate Prediction and Research (of all places!) states “In order to understand the greenhouse effect on Earth, a good place to start is in a greenhouse. A greenhouse is kept warm because energy coming from the Sun (in the form of visible sunlight) is able to pass through the glass of the greenhouse and heat the soil and plants inside. But energy which is emitted from the soil and plants is in the form of invisible infrared (IR) radiation; this is not able to pass as easily through the glass of the greenhouse. Some of the infrared heat energy is trapped inside; the main reason why a greenhouse is warmer than the garden outside.” With science in this state, is it any wonder that the global warming brigade is such a shambles?

  72. The AGW people (Alarmists on Global Warming) look at the planet as a bottle. Not surprising, after seeing the Monckton interview whit that greenpeace woman.

    hehe.

    What is interesting here is that BBC claims that FSB is behind Climategate. And BBC is basically the UK government.

    Will be interesting to see the FSB response. Will they leak who the leak is because of this? Interesting times.

  73. Doesn’t this ‘experiment’ show the true beauty of the AGW fraud? You can easily hoax people with no scientific background, if you use some ‘known and trusted’ person or entity, to push the hoax. Is this why the the AGW often use movie stars to hoax people? Or are they victims themselves.

    The most dangerous thing of all is what people think they know as truth and it’s just not so. For example — More CO2 given off by man heats the earth is plausible to most people. Of course many don’t even know what CO2 is, but — When someone they know, and ‘trust’, says it, like Al Gore(or the BBC) people fall for it. Especially when you do an ‘iffy’ experiment that ‘proves it’, and use of experts to show all is well with and validate their experimental method.

    The bad part — Politicians know all about this approach to selling junk science for political ends. This process happened with the junk science of DDT, and more than 30 million Africans, mostly children under the age of 5, died for this hoax. Today after 30 plus years of trying, WHO reauthorized DDT for use, finding no harm to man or planet.

    Real science is not easy … It takes meticulous work to produce real science.

  74. Tom Segalstad says this in the youtube info area;

    This video shows that a candle floating on water, burning in the air inside a glass, converts the oxygen in the air to CO2. The water rises in the glass because the CO2, which replaced the oxygen, is quickly dissolved in the water. The water contains calcium ions Ca++, because we initially dissolved calcium hydroxide Ca(OH)2 in the water. The CO2 produced during oxygen burning reacts with the calcium ions to produce solid calcium carbonate CaCO3, which is easily visible as a whitening of the water when we switch on a flashlight. This little kitchen experiment demonstrates the inorganic carbon cycle in nature. The oceans take out our anthropogenic CO2 gas by quickly dissolving it as bicarbonate HCO3-, which in turn forms solid calcium carbonate either organically in calcareous organisms or precipitates inorganically. The CaCO3 is precipitating and not dissolving during this process, because buffering in the ocean maintains a stable pH around 8. We also see that CO2 reacts very fast with the water, contrary to the claim by the IPCC that it takes 50 – 200 years for this to happen. Try this for yourself in your kitchen!

    More background info at http://www.CO2web.info

  75. Arthur Glass (05:08:22) :

    ““Current atmospheric CO2 content is 388 ppmv, which is 0.0388%, not 0.000388%.”

    ??? Surely the latter number is correct. 0.0388 would be 388 parts per 10,000 –two orders of magnitude difference!”

    It is 0.0388% Don’t forget it’s a percentage.

  76. Just to recap, we still have one last objection:

    When a person:
    – isn’t paid by oil companies
    – is a scientist
    – is not a crank
    – is in the field
    – is peer reviewed
    – and is nonetheless sceptical

    then the last objection is, “he is just one person being irresponsible”.

    Until we address the core values of greenies—those values that lead them to believe that they are better people—then we will continue to discover that “the science” never really mattered to them in the first place.

  77. @Arthur Glass
    “??? Surely the latter number is correct. 0.0388 would be 388 parts per 10,000 –two orders of magnitude difference!”

    Not if you are talking about percentages. For instance, 0.01 = 1%, so 0.000388 (388 ppmv) = 0.0388%.

  78. If I recall correctly, plastic blocks UV and some IR radiation. It seems to me that this experiment is primarily measuring the radiation that makes it through the plastic.

    If AGW (CO2) increases the radiation hitting the earth we should be able to directly measure that increase over time as the CO2 levels increase. Where is that measurement?

  79. The experiment must be performed “dry” to eliminate the variable of heat absorption due to water vapor. In other words, the humidity must be identical in both bottles and a dessicator should be used to eliminate as must moisture as possible.

    So the CO2 should be added to the experimental bottle from a CO2 generator or compressed supply.

    Assuming everything else is consistent, you now have a controlled experiment!

  80. Arthur Glass (05:08:22) :

    “Current atmospheric CO2 content is 388 ppmv, which is 0.0388%, not 0.000388%.”

    ??? Surely the latter number is correct. 0.0388 would be 388 parts per 10,000 –two orders of magnitude difference!

    380 ppmv = 0.00038 fraction by volume = 0.038%

    Try it.

    Excellent discussion of the difficulties in trying to ascribe huge powers of thermal blanketing to atmospheric CO2. Very lucid; I’m saving it to show to others.

    /Mr Lynn

  82. i know this is a repeated thought but as pressure goes up so does temp. one should compare temp increases with no lights involved and see if temp goes up. also luminosity increases or decreases with the square of the distance and who knows how if the lamps are at same distance. I think even a cm difference could make a big difference. looks like lights are not aligned equally either probably on purpose.

  83. tokyoboy (00:38:13) (and others) :

    Probably not quite OT, but the Team and their relatives say that the recent gradual temperature decrease in the stratosphere evidences that the anthropogenic CO2 is warming the troposphere.

    Only if you believe the graphs shown on this page show a “gradual” cooling.

    http://www.acd.ucar.edu/Research/Highlight/stratosphere.shtml

    I’ve seen it argued that ozone depletion in the stratosphere leads to cooling and the “recovery” of the ozone layer accounts for the halt in cooling of the stratosphere, but it seems to be a bit of a stretch to argue that the recovery of the ozone layer in the stratosphere is exactly enough to offset the effect of ghgs in the troposphere.

    For some reason, the word “epicycle” comes to mind.

  84. Dave UK (04:56:08)

    O/T, sorry but for all UK non-TV viewers;

    Don’t waste your money, you only need a BBC licence to watch TV at the same time as it is broadcast (by any station). Not needed for recorded shows (as long as you don’t record them yourself of course) including on BBC’s iPlayer. You can only be fined if you are caught watching as it is being broadcast (in any medium). Even if you are watching you can only be caught if you let the Teleban (geddit?) into your house or close enough to look through the window. The detector vans are a fraud (not another!) and have never been used as evidence.

  85. The basic problem is that the CO2 absorption lines are already pretty opaque at sea level. Adding more CO2 to that region will not make them significantly more opaque. Its like being placed on the floor and having a sheet of plywood put on top of you. You then get an elephant to stand on the sheet of plywood. You are pretty much toast. Adding a second elephant does not really change anything. The only result of adding CO2 and global warming is to push the point where the atmosphere becomes a bit more opaque further up into the troposphere. Down here at ground zero, the difference it makes is zero.

    The whole greenhouse thing is a flawed concept put off on people who have been instructed by the run of the mill high school science teacher. [Not to insult high school science teachers, they start off trying to fix a defective product anyway]. Greenhouses and cloches work by having the stuff absorb the radiation and convert it to heat and then not be able to get rid of it by convection.

    Stupid 101, thy name is the morons that try and teach science to the masses. Most people are more interested in the Simpsons or some bs reality show than they are in what makes the world work.

  86. The whole idea of runaway green house gasses was originally based on the extreme temperatures of Venus. So the earths atmosphere has .00038% carbon dioxide. The atmosphere of Venus has about 90% carbon dioxide. Can anybody tell me what the actual increase of CO2 has been? I’d look it up but I don’t trust Wikipedia any more. I’d rather hear it from one of you.

    Thanks

  87. I have made a formal complaint to the BBC, text below, and wait to see what response they offer.

    “Some 13 minutes of the Newsnight programme were given to Justin Rowlatt showing a kitchen experiment to “Prove Global Warming” with two ‘top British scientists.
    The ‘experiment’ was conducted by Dr Maggie Aderin Pocock who whilst qualified in physics and mechanical engineering is by no stretch of the imagination a top British scientist.
    She then set up a totally misleading ‘experiment’ that completely filled one container with CO2 (because it is heavier than other air components and would have filled the bottle from the bottom up) whilst leaving the other with normal air inside. To be at all representative of the effects postulated by the AGW scientists she should only have added some 200 parts per million of CO2 to the air in this bottle i.e. just a few molecules. Her/Rowlatt’s bottle being full of CO2 would obviously have a greater tendency to absorb heat that the plain air one so this was a clear fraud perpetrated on people with no science knowledge at all.
    Having produced a fraudulent ‘experiment’ Rowlatt then allowed Sir David King to make unchallenged statements about the emails leaked from UEA/CRU – implying a foreign intelligence-led hacking. He was also allowed to forecast huge sea level rises and othe effects as if they were imminent whereas, IF warming theory is right, they would be a couple of centuries or more away.
    The BBC should not put out such one sided and clearly fraudulent information and the BBC Trust should not allow it to happen.”

  88. My son and I did a similar science experiment at home a couple of years ago, without showing any temperature difference between the CO2 bottle and the air bottle. We weren’t very sophisticated, of course.

    This article brings something else to mind for me, though it may only be tangentially related. All metaphors break down eventually, or course, but the ‘greenhouse’ metaphor doesn’t seem to really get very far in describing what really happens in the atmosphere. In a greenhouse the heat absorption that matters is the heat absorbed by the physical structures in the greenhouse, including the glass, and the fact that IR energy doesn’t pass through the glass the way the light energy does. So it is trapped inside, at least relative to the light. That doesn’t have a lot of relevance to the atmosphere since there is no glass surrounding it. The light energy is, of course, absorbed by the earth itself, and the gas in the atmosphere. But the trapping of that heat in the greenhouse is much different.

    I have looked for any data supporting the idea that it is the gas itself in the greenhouse that makes the difference. In my limited search I could find no claims from botanists, etc, that increasing the CO2 in a real greenhouse has any effect on the temp inside. They do, of course, pump CO2 into some greenhouses, but only because it stimulates plant growth. More CO2 makes for more effective photosynthesis. And greenhouses are, of course, warmer than the ambient temp outside. But the increased temp in a greenhouse comes from an altogether different mechanism, not the CO2. At least the vast majority of it.

    Does anyone else have any comments about that?

  89. The BBC manages to inject some reference to AGW, as if it was an unquestionable article of faith, into roughly every other programme. It’s clear they see themselves as evangelists.

    This sort of crude, shameless propaganda is exactly what you’d expect from them. They are of course, completely impervious to criticism and generally, simply ignore it.

  90. @ Martin Judge…I agree with Anthony…. ‘Despair I understand, submission I do not.’
    @ Barry Foster, same applies.
    @ mikef2 and AndyN (plus anuone else) KEEP GOING…..but to be more effective, get your MP involved and get him to write directly to:

    Mark Thompson Esq
    Director General
    BBC Broadcasting House
    Portland Place
    London
    W1A 1AA

    Mark your envelope: Strictly Private & Confidential

    Be prepared for a long battle, I have been trying for over 3 years….or, as I have now done, ask your MP to refer it to the Culture, Media and Sprort Select Committee.

    Good luck!

  91. From the BBC website:
    “One of the problems underlying the climate change debate is that whatever the majority of scientists say about global warming a lot of people remain sceptical about whether climate change is really man made.”

    Even if this experiment is done well, in what possible way does it prove that global warming is man made? If man’s CO2 output was more than a tiny fraction of the total CO2 in the atmosphere, then they might have a case, but it’s not.

  92. “Mobile Phone Conversations.” Beeb turns away from grey propaganda, enters Black Propaganda mode now. They must be pretty desperate.

  93. crosspatch (01:25:30) wrote a lot of interesting information that I have had to snip for length. What I question is: “…..CO2 absorbs radiation from two sources. It absorbs heat radiation from the ground but it also absorbs solar radiation. The majority of the Sun’s energy reaches Earth as infrared. Greenhouse gasses will act to block some of that infrared from reaching the ground. A molecule that absorbs a photon from the sun has a 50% chance of re-radiating that photon back toward the ground…..”

    It is my understanding that CO2 does not absorb incoming (solar) short-wavelength IR radiation, but does absorb outgoing (from the earth) long-wavelength IR radiation.

  94. jmrSudbury (04:55:48) :

    I wonder if the humidity increased due to the water/bakingsoda/vinegar reaction.

    crosspatch (01:25:30), window panes of the popular sealed unit variety are a maximum of 12 mm aprt, so convection currents do not increase the rate of heat transfer.

    John M Reynolds

    I too wondered about transfer of H2O along with the CO2

    As regards sealed units, typical spacing is from 12 to 24mm, most common being 16 or 18mm. The only people I’ve come across using less being John Carr Joinery of Doncaster who used 6mm.

  95. “And BBC is basically the UK government.” No it isn’t. Both are loathsome but they are not the self-same creature.

  96. Maybe slightly OT, but still relates to CO2. Only not in bottles. This one is about cows, the EPA, and lawsuits.

    Excerpt:

    NCBA Files Petition Against EPA Endangerment Finding

    I didn’t know my wife was so diligent about checking my blogs, but apparently she is. I’m in hot water regardless.

    Coming out of the gate on Christmas Eve,The National Cattlemen’s Beef Association has become one of the first groups to legally challenge the Environmental Protection Agency’s recent greenhouse gas endangerment finding rule.

    I’m thinking there must be some symbolic religious tie-in here. Perhaps NCBA is trying to demonstrate that childbirth in a stable and baby care in a manger would not be allowed under the EPA greenhouse-gas rule. Anyway …

    According to a news release Thursday, NCBA filed a petition Wednesday in the DC Circuit Court of Appeals.

    “EPA’s finding is not based on a rigorous scientific analysis; yet it would trigger a cascade of future greenhouse gas regulations with sweeping impacts across the entire U.S. economy,” stated Tamara Thies, chief environmental counsel. “Why the administration decided to move forward on this type of rule when there’s so much uncertainty surrounding humans’ contribution to climate change is perplexing.”

  97. There is no question that increasing atmospheric CO2 will cause some increase in temperature. The discussion needs to move to “how much?”

  98. The upload on to the Russian file-sharing server was made via a Turkish proxy server which is well known and was accessed by a Mac using Netshade. That Turkish proxy server, which is open to all, is owned by a consortium known as the Russian Business Alliance, who dabble in all sorts of illegal activity, piracy and espionage and have links to the FSB.

  99. Sorry, scratch that last post as it wasn’t completed.

    The upload on to the Russian file-sharing server was made via a Turkish proxy server which is well known and was accessed by a Mac using Netshade. That Turkish proxy server, which is open to all, is owned by a consortium known as the Russian Business Alliance, who dabble in all sorts of illegal activity, piracy and espionage and have links to the FSB.

    The Russians have so far said that the upload was not made from Russia but probably from the UK.

  100. I’ve always wondered how the CO2 warming equation was derived. In a simple way, I would think that somebody built equal sized greenhouses and filled each one up with different amounts of CO2 (all else being equal), recorded the temperatures and came up with the equation.

  101. Smokey (04:15:36) :

    Trefor Jones (03:51:49),

    “The BBC has an “Ethical Man”?? That’s really very funny. Is it a parody? Does he wear a clown suit? Or is he really that insufferable?

    If I went to work for the BBC, could I be “Superior Man”? “Wonderful Man”? “Totally Honest Man”? “The Pope’s Supervisor”?

    Do BBC employees get to pick whatever title they want, no matter how silly?”

    They certainly don’t have a Skeptical Man or an Honest Man (they don’t recruit in Ayr Scotland for that reason -Ref Tam O’Shanter R Burns).

  102. Can somone tell me who exactly is arguing that co2 cannot “retain heat”?

    Last time I checked that wasn;’t the real issue being debated among scientists (and last time I checked the earth wasn’t contained in a bottle either).

    Perhaps the BBC could spend some time on the real issues instead of screwing up experiments to knock down a strawman argument.

  103. Arthur, J

    ohn above is correct re: Reader Brian C.’s letter states:
    “one containing ‘atmospheric air with a greater concentration of carbon dioxide’ (they didn’t say how much they were adding, of course, but I’d bet it was substantially more than 0.000388%!).
    Current atmospheric CO2 content is 388 ppmv, which is 0.0388%, not 0.000388%.

    388 ppm is 0.0388%. For example, 1% of 1,000,000 ppm is 10,000 ppm. 0.01% would be 100 ppm. So, 388 ppm would be 0.01% x 3.88 = 0.0388%.

  104. The man in the grey jacket knows not only the e-mail were hacked, but knows why they were hacked and “knows their strategy”

    He lies. He hasn’t met the people and has no idea what their strategy is. Does he read minds of people for which he doesn’t even have names?

    He makes stuff up.

  105. I could not watch it. What is point of bringing in scientists to conduct a “very unscientific experiment”, unless it is to convince the audience that the unscientific experiment is actually scientific? This crowd looks very easy to to convince. You know you have an unquestioning lot when one guy thinks that putting a brick in his toilet will some how reduce global warming.

  106. crosspatch (01:31:24) :

    Also notice the water droplets on the inside of the bottle in figure 3. That says the atmosphere inside the bottle is saturated with water vapor and it is condensing on the inside of the bottle.

    Indeed, water in the bottle is a confounding factor, but we were following the prescription of NOAA, remember. CO2 absorption bands are a bit different from H2O vapor and so the small difference we observed is repeatable and unsurprising. There is a long, long list of things wrong with this experiment, which is the learning lesson it provides. We learned it, the BBC did not.

  107. For non science people is see several questions non science people do not know to ask.

    They don’t have measurements for the temps of the vinegar or the Na bicarb.
    They also don’t have readings of bottle temps which have no light added. Remember much of our 24 hour day is dark.

    We of course see no sample of CO2 that is similar to real life.
    The Dr looks like Aunt Jemima. I wonder if she uses Aunt Jemimah pankake mix and measures the elevation of temps from the chemical reaction of baking soda and water when the mix is prepared. Some reactions give off heat and she didn’t mention that.

    There are a long list of sloppy experiment techniques she uses that tell me she is a great teacher for gullible students. She also didn’t measure the humidity in the 2 bottles. It would have to also be equal. I haven’t read all the posts but know of several questions that haven’t been raised to even get to the point of the experiment being a clean one.


  108. “Let me also make this allegation for the first time in public. It’s an extraordinarily sophisticated piece of work to hack into all of these emails and mobile phone conversations, right?”

    No; give me access to ‘the switch’ (literally: the MTSO, “Mobile Telephone Switching Office” see) and the world is yours …

    Alternatively, find a ‘switch tech’ who wants to be on ‘your payroll’ (ref Kevin Mitnick see). Kevin made use of many physical security holes overlooked by most people including the so-called ‘security experts’; the sewing together of many bits of info obtained form different sources enabled him to pull off what we did without being extraordinarily sophisticated.

  109. MarkW (05:06:38) :

    They are using seltzer tablets dropped into water to create the CO2.

    Was there any attempt to account for what the fizzing tablet did to the water vapor inside the “CO2″ bottle? I would expect it to have a much higher amount of water vapor compared to the non-CO2 bottle.

    We thought about the tiny fiz-generated droplets making the air more humid. As others have pointed out there is some consensation on the bottles which shows saturation with water vapor. Interestingly, not all of the bottles show the condensation, and they are not consistently from the CO2 or non-CO2 group. We have interesting issues with the HVAC in that lab, so I suspect some bottles have a slightly cool exterior–yet another confounder.

  110. The more I think about this experiment, the more convinced I become that it is a perfect experiment to highlight the catastrophic AGW hypothesis. Because it is such a poorly designed experiment, the huge error bars on the measurements allow the observer to conclude anything. Its the perfect experiment for policy-based evidence-making.

    The situation is identical with surface temperatures, cloud cover, precipitation, sea ice cover, glacier mass, sea levels, ocean pH, etc, etc etc.

  111. kwik (05:31:50) : Dear kwik, nice experiment!. However we need a team of psychiatrists to explain the hysterical passion exibited by some europeans prime ministers after the copenhagen fiasco. One of them said: “we will have to change world institutions to make possible a success in Mexico”.
    Let me tell you that her Gaia goddess is conspiring against them: Today it is snowing on the southamerican andes, closing highways, where the so called global warming deglaciation (btw.absolutely cyclical) took place. Take into account that south of the equator we are in summertime.

  112. Bob Koss (01:27:58) :

    How can the air temperature be dropping?.

    The first look we get at the temperature readings, the normal air reading was 35.6c and the co2 was 34.0c. You see them change to air 35.5c and co2 34.7c. Last reading is air 34.6c and co2 38.7.

    It also appears to me the co2 lamp is slightly lower relative to the bottle.

    There are a scad of things wrong with the BBC experiment. The worst is that by using two lamps rather than one, the scientists added yet another confounding factor. She had the thermocouples resting diagonally (it looked) in the bottle, so adding more confounding, had the lamps extremely close (so making the results more sensitive to location) and had the lamps pointed at the centers of the thermocouples, when the sensing element is probably down near the tip–maybe she was after the air temperature, but the sheath will conduct heat down to the tip anyway. But the behavior of the thermometers simply showed the residue of earlier trials. Well, the BBC “experiment” was not meant to prove anything, but to make a point.

  113. Well, now we know why climate scientists prefer computer models. They apparently have no idea on how to set up valid experiments.

  114. Another let-down by the BBC was a trilogy called ‘The Climate Wars’. My memories of it are :

    The presenter started out by proclaiming to be open minded about the debate, and he did go through the issues of temperature anomalies in built up areas, etc. My first twinge was when he was demonstrating CO2 as a greenhouse gas where he had a long clear plastic tube filled with air and showed a heat source through it, he then filled it with 100% CO2 and showed that the heat source was no longer detectable! If he had used the atmosphere with the CO2 removed, and then with the correct proportion of CO2 added and THEN shown the difference it would have at least been of some relevance.

    The program also featured some climate skeptics who had apparently capitulated and agreed that at least some warming was man-made! The turning point was the hockey-stick graph. The argument seemed to be that if there were two competing theories, the sun versus CO2, when the hockey stick ‘proved’ it could not be the sun, but as CO2 levels matched the hockey-stick all the way, then CO2 was the cause.

    I did not watch the third program on computer ‘models’. Unless a computer model can take the values of Earth’s atmosphere when life began [A LOT of CO2] and get reasonable temperatures it is invalid.

    Also the close correlation between CO2 levels and global temperatures proves that it can not be CO2! It could only be true if there was absolutely no other influence, and then we get into the area where solar activity is governed by Earth’s CO2 levels.

    To me natural CO2 levels seems to be a thermometer, which is why it lags changes in global temperature. Man-made CO2 seems to be like putting a candle next to a thermometer in a greenhouse. The thermometer may show a large increase but the actual rise in the greenhouse will be tiny.

    The BBC showed these programs again during the Copenhagen conference, even though post Climategate the hockey-stick is even more questionable.

  115. ralph (04:17:38) :

    Should the thermocouple not be shaded from the lamps – to prevent radiant energy simply creating an increase in temperature in the thermocouple itself (and not the gasses). Stevenson Screens are shaded, so surely the thermocouple should be.

    The way we figured it, we were interested in the equilibrium temperature of the thermocouple just as though it represented the surface of the earth. The experiment is just a mess anyway, and so why put much more effort into trying to improve it? It works well to illuminate other lessons.

  116. I saw the original version of the BBC Newsnight programme and was utterly appalled and amazed by such a naked piece of propaganda and infantile (and incorrect) science. I nearly threw the TV set out of the window. I am planning to lodge a formal complaint to the BBC Trustees and OfCOM. Anyone want to join in?

    Christopher Booker quotes the BBC’s editorial policy in his wonderful book ‘The Real Global Warming Disaster’ on p248 as follows:

    “BBC News currently takes the view that their reporting needs to be calibrated (sic!) to take account of the scientific consensus that global warming is man-made. The BBC’s Editorial Guidelines, issued to all editorial staff, state that ‘we must ensure we avoid bias or imbalance of views on controversial subjects'”….

    Can you believe it. They are telling themselves that they do not need to be balanced on global warming because it is NOT controversial (there’s a consensus, stupid). As Booker puts it, ‘In the name of reporting impartially, it sees no need to report impartially.’

    It is time the BBC was held accountable for its Charter obligations of impartiality in regard to the AGW propaganda exercise. So start lodging your complaints.

  117. This is the same Dr. King:

    “Andrei Illarionov, former chief science adviser to President Putin:
    … in respect to the presentation made by representatives of the so-called official team of the British government and the official British climate science, or at least how they introduced themselves at the seminar. I personally was surprised by the exceptionally poor content of the papers presented…

    Simultaneously, they revealed an absolute—and I stress, absolute inability to answer questions concerning the alleged professional activities of the authors of these papers. Not only the ten questions that were published nine months ago, but not a single question asked during this two-day seminar by participants in the seminar, both Russian and foreign, were answered.

    When it became clear that they could not provide a substantive answer to a question, three devices were used… The British participants insisted on introducing censorship during the holding of this seminar. The chief science adviser to the British government, Mr. King, demanded in the form of an ultimatum at the beginning of yesterday that the program of the seminar be changed and he presented an ultimatum demanding that about two-third of the participants not be given the floor.The participants in the seminar who had been invited by the Russian Academy of Sciences, they have been invited by the president of the Academy of Sciences Yuri Sergeyevich Osipov. Mr. King spoke about “undesirable” scientists and undesirable participants in the seminar. He declared that if the old program is preserved, he would not take part in the seminar and walk out taking along with him all the other British participants.

    He has prepared his own program which he proposed, it is available here and my colleagues can simply distribute Mr. King’s hand-written program to change the program prepared by the Russian Academy of Sciences and sent out in advance to all the participants in the seminar.

    A comparison of the real program prepared by the Academy of Science and the program proposed as an ultimatum by Mr. King will give us an idea of what scientists, from the viewpoint of the chief scientific adviser to the British government, are undesirable. In the course of negotiations on this issue Mr. King said that he had contacted the British Foreign Secretary Mr. Straw who was in Moscow at the time and with the office of the British Prime Minister, Blair, so that the corresponding executives in Britain should contact the corresponding officials in Russia to bring pressure on the Russian Academy of Sciences and the President of the Russian Academy of Sciences to change the seminar’s program.When the attempt to introduce censorship at the Russian Academy of Sciences failed, other attempts were made to disrupt the seminar. At least four times during the course of the seminar ugly scenes were staged that prevented the seminar from proceeding normally. As a result we lost at least four hours of working time in order to try to solve these problems.

    During these events Mr. King cited his conversations with the office of the British Prime Minister and had got clearance for such actions.

    And thirdly, when the more or less normal work of the seminar was restored and when the opportunity for discussion presented itself, when questions on professional topics were asked, and being unable to answer these questions, Mr. King and other members of the delegation, turned to flight, as happened this morning when Mr. King, in an unprecedented incident, cut short his answer to a question in mid sentence realizing that he was unable to answer it and left the seminar room. It is not for us to give an assessment to what happened, but in our opinion the reputation of British science, the reputation of the British government and the reputation of the title “Sir” has sustained heavy damage.”

    It’s the mad hatter’s tea party

  118. Either their well-placed “skeptic” Phillip is a complete dumb*ss or is a plant. To go from being a skeptic (albeit one with an obligatory brick in his toilet) to being convinced that he would be an “idiot for not believing” and willing to “gladly pay [more taxes to solve AGW] tomorrow” over the course of a bogus kitchen experiment and some misleading statements from a “top scientist” is just too convenient.

    It has been clearly demonstrated that if you’re skeptical like Phillip, you would be an idiot not to change your mind based on this experiment and pay more taxes tomorrow as well. This reeks of infomercial.

  119. Bruce (01:47:41) :

    “This is a huge scoop! Who knew there were mobile phone conversations hacked? Only the FSB or the CSIS could/would do that! Which was it? Were they working together? The world needs to know! Why was such huge news slipped out like that? Did Sir David reveal this by mistake? Does he know too much? Is his life now in danger? Ian Fleming, eat your heart out – real life is much more exciting than your mundane stories!”

    For what it is worth I was talking to a guy with CIA connections. He said British Intel and our CIA swap favors because although our laws make surveillance by our FBI and CIA illegal they do NOT cover British Intel. Therefore the spying is done by a foreign intel service and turned over to the national. Truth? Heck if I know but it would not surprise me.

  120. The flood of complaints may give the BBC some food for thought but, if it’s anything like the EPA, the nett result is likely to be zero!
    When that latter organisation went ahead on that ill-fated day, December 7th 2009, with the infamous ghg pollution endangerment finding it did so on a Tsunami of public comment!
    This from the EPA site:
    EPA issued the proposed findings in April 2009 and held a 60-day public comment period. The agency received more than 380,000 comments, which were carefully reviewed and considered during the development of the final findings.
    Over 6000 comments a day and I’d be extremely surprised if the majority were supportive of the planned actions!
    How did they manage to process this enormous volume, how did they extract the evidence that they’d asked for to lend legitimacy to the process and where is the report that presumably had to be produced?
    Anyone know? FOIA anyone?

  121. Molon Labe (01:14:18)

    Below is charted the calculated Specific Heat
    (at constant pressure) for dry air @300K.

    Molecule %/Atm Cp Cp-Atm
    N2 78.08 1.039 0.8113
    O2 20.95 0.918 0.1923
    Ar 0.93 0.521 0.0048
    CO2 0.036 0.846 0.0003
    Ne 0.0018 1.031 0.00002
    He 0.0005 5.196 0.00003
    Dry Air 99.9983 1.00875

    In the following chart the CO2 is doubled and
    the N2 and O2 percentage reduced proportionally.

    Molecule %/Atm Cp Cp-Atm
    N2 78.053 1.039 0.81100
    O2 20.941 0.918 0.19224
    Ar 0.93 0.521 0.0048
    CO2 0.072 0.846 0.00063
    Ne 0.0018 1.031 0.00002
    He 0.0005 5.196 0.00003
    Dry Air 99.9983 1.00872

    So doubling the CO2 has almost no effect on the
    Specific Heat of dry air.

    Left out of all this is water vapor which can vary
    from 0-4%. The saturated vapor at this temp would
    have a Cp of around 1.37 kJ/(kg)(K).

    REPLY: Your most effective actions are to stop paying the TV license tax. Watch TV on your PC. – Anthony

    Sorry, but in comments I’ve read the UK government seems to have that one covered as well, it’s television programming therefore it’s a TV therefore you pay the tax.

    Do they still make radios that pick up the audio of TV signals? Did the BBC broadcasts go digital and do they have radios for that? It’s still TV programming therefore they may be taxing the radios as a TV. Don’t blind people pay the tax, and they don’t use the video either?

  123. REPLY: Your most effective actions are to stop paying the TV license tax. Watch TV on your PC. – Anthony

    Watching live TV on your pc still requires a licence in the UK – watching tv real time through any medium requires a licence.

    I don’t think, in the experiment as screened, any extra CO2 could have been in the “global warming” jar. It was only 20 seconds between putting the bicarb in the feeder bottle (2:30), putting in the connecting tube (2:35) and then removing the connecting tube (by 2:51 it was gone, though we didn’t see it removed). Not even enough time to expell all the existing air in the tube, let alone the air in the feeder bottle.

    Of course the experiment wasn’t as screened, as indicated by the various commentators above.
    I wonder what temperature the air in the feeder bottle was – there was no thermometer measuring that.

  124. Thanks for the laughs. That was one of the funniest videos I have seen in a long time. I can’t stop laughing!

    Ummm…..it was meant to be funny….right?

    The complete failure to include any actual science in this experiment has been well demonstrated by everyone else, but the red herring concerning great skills, resources and organization needed to obtain and distribute the emails is yet another case of fear mongering. The evil organization operating from an underground base on a volcanic island in the Pacific, straight out of james Bond. Give me a break. A 14-year-old script kiddie in his parents’ basement could have done the job over the course of a bag of Doritos and a Mountain Dew (standard script kiddie nutrition). Russian servers are weak and widely used as distribution points. You could get a list of vulnerable Russian servers as long as your arm at any blackhat site. Besides, this wasn’t a hack….it was a inside job pure and simple.

  125. Not sure where I just saw it in connection with the “explanation” of this bogus experiment, but the notion that Venus is hot because of CO2 with no mention of it in relation to the sun is most peculiar.

    Global warming seems to me to be another Galileo/hubris thing. In his time the sky revolved around the earth. Poor guy tried to point out man was not the center of the universe, that the earth revolved around the sun.

    Today, we “know” the sun’s warmth *never* fluctuates more than 0.01% and cannot possibly have as much to do with climate as mankind. I’m thinking maybe the Hawaiians had something there. Perhaps there is a need to sacrifice more virgins to volcanoes to make them stop belching.

  126. Anticlimactic (08:12:21) :

    Another let-down by the BBC was a trilogy called ‘The Climate Wars’.
    I also remember this trilogy. Dr Iain Stewart’s open minded (?) analysis of the AGW debate.

    Typical BBC – high production values, superficial analysis and a schmaltzy ending.

  127. kadaka (08:57:28) :

    There is no licence for radio in the UK – and I’ve never had a radio that could pick up the sound from TV, though I don’t have a digital radio.

    The snow is all melting, so it might not be a white Christmas after all. Boo hoo.

  128. On the plus side, it would save Joan Ruddock, Miliband E., and world saviour Gordon ‘I wasn’t invited but I’ll claim I was running the show’ Brown from blowing about £5,999,997.50 of public money we don’t have left to ‘create’ their next award-winning ad in the ‘campaign’ by just running a (further) edited (to enhance the narrative) version of this, over and over, on all BBC Broadcast Outlets.

    Which will probably fare with a properly objective ASA about as well as the previous ‘scientists say’ efforts they have charged us for.

    Important message. So far being botched by a venal and/or inept bunch of messengers.

    With some involved we do have recourse at the ballot box every few years. With the BBC, well, like its funding, so much remains, forever, ‘unique’.

  129. “Partially fill both bottles with water. In fact, we filled each with the same amount of water – about two inches worth.”

    A very odd statement to me, 2″ of water? Why not use a fixed volume?

  130. I am interested that few look at the impact of convection. Even the article at top of this thread glosses over it.
    Warm CO2 will rise and surely that in itself cools it cos of work done against gravity, and other effects (expansion of surrounding upward convection currents, no doubt neither purely isothermal nor purely adiabatic), tho’ some of the energy will go into surrounding air packets. If convection goes into the stratosphere, and/or causes turbulence lower down, surely that will increase the outward radiation transfer, thus reducing the temperature rise necessary to reestablish overall radiation balance? Also, if there is any net expansion of the atmosphere – due continuing CO2 enhanced convection and any actual warming – won’t that increase the effective into – outer – space radiating surface? (and sustaining that expansion against gravity would absorb energy?)
    The net of all this, together with CO2 absorbing IR on the way in from the sun ( and so reducing ground insolation and the CO2 being more “saturated” with energy) seems to me to underline how feeble its effect must be, especially at 338ppm.
    As an aside, to be fair to warmists, the sun’s spectrum is approx 20% UV, 40% visible and 40% IR (I recall!) thus plenty of visible to heat the ground and reradiate as IR, even with GHG absorbing i/c IR.
    But I have seen little qualitative explanation of how radiative balance is reestablished following an increment of CO2 in the atmosphere. The implication that it is mainly by lower atmosphrere temperature increases never seems to be explained in any detail, but perhaps it is too mathmatical for qualitative explanation with simple breakdown of the energy flows and destinations by %. Or maybe the AGW alarmists have just siezed on a simplistic or wrong causal model to explain apparent correlations?
    Views?

  131. REPLY: Your most effective actions are to stop paying the TV license tax. Watch TV on your PC. – Anthony

    Thanks, Anthony. I’m up for it, but have to persuade the wife… Maybe I’ll go in stages; letter to the BBC DG cc’d to my MP, approach to Culture, Media and Sports Minister, OfCOM etc, then withdrawal of licence fee (tax).

  132. The program was presented by Newsnight’s ethical man, Justin Rowlatt.
    It’s purpose was to bolster the faith of faltering believers.

    Under the guise of trying to convince hardened skeptics, the “experiment” was the highlight. With some pitifully transparent propaganda, the finale showed that most of the “skeptics” were now convinced, vowing to change their lifestyles drastically.

    What stood out most of all was how unconvincing the skeptics were in their role. I seriously believe they were either actors or activists.

    No point complaining to the BBC though, they’re too far gone.

  133. To simulate the earth “Green House” effect, there is a major problem in those experiments.
    Consider the earth-sun set-up. The sun is not shining the same air mass 24 hours a day. if the air with more CO2 got higher temperature during the day time,then it would radiate energy out faster than the cooler air during the night time.
    the question is how much extra heat accumulation each day?
    Those experiments did not simulate the cooling time.

    Second, the earth atmosphere has no cover, it is totally open. The bottle is a totally closed environment. that’s a big difference.

  134. So let’s recall what we saw. Two very unscientific pieces of apparatus; water bottles unknown output lamps etc. So the allay suspicions of fairness, they turned the lamps on with both bottles full of ordinary air, and showed that their temperatures exactly tracked, so there was no difference between the two set of apparatus.
    Then along came this pink elephant and farted; excuse me, that’s flatulated in one of the bottles, and changed the atmosphere so then it cooled down; hic, scuse me mate, I didn’t quite catch that, could you refresh my memory; oh dear I think I going to burp, hic, well they sure talked funny.

    I think I could probably sell most of them, hic, the London Bridge; including that BBC duffer who didn’t notice how the heat lamp cooled the bottle of ordinary air; ‘ang on mate, while I get anover Newcastle Brown Ale, hic !

  135. A similar “experiment” was performed on the Discovery Channel’s hit series “Myth-Busters” It was a “kid science” special episode.

    Some young fans of the show were invited to join the hosts to perform various experiments including the CO2 temperature one.

    The result of course was that CO2 retains heat (shocker!).

  136. I wonder why the kitchen was so hot — could it be that at lower temperatures the experiment was complicated by condensation on the inner surfaces of the experimental bottles? If so, maybe they could have used that complication to carry the science a little further by explaining that the big unknown in climate science is cloud behaviour, condensation of the water vapour in humid air.

    But that, of course, would have been science rather than propaganda.

    Has anyone tried the experiment with both bottles holding a pint of water and an external temperature of, say, 12 degrees? If the lights were not so close I’d expect the results to be interesting.

    JF

  137. It would be of value to consider the following when running this experiment:
    a) swap the thermocouples, run the experiment again, and average the results to cancel out the differences in TC characteristics.
    b) run the experiment again doubling the moisture to show the effect of increased water vapor which has 26 times more of a spectral absorption bandwidth or global warming influence than does CO2. (When the BBC starts out with room temperature, superheated, winter air, there is very little moisture to begin with).

    Better still, duplicate Dr. Heinz Hugs’ experiment which demonstrates that doubling CO2 results in a 0.012C increase.

    Even better still, show what happens when wv is doubled and CO2 is left alone!

  138. The only TV science out of the U.K. I’ll watch is Top Gear.
    Lots of hot air, but their honest about it, with entertaining video to boot.

  139. Just as asinine is this video of NOAA cheif Jane Lubchenco doing a little experiment /demonstration in a congressional hearing.

    Jane claimed that our CO2 emissions are making the ocean so acidic parts are already corrosive and are causing sea life to suffer from a kind of osteoporosis.

  140. A British scientist named Wood did an experiment, reported in a paper in 1909, which is said to have disproved the green house gas warming theory. I do not know if that conclusion is correct as I am not a scientist, but perhaps it is time the experiment done by Wood was repeated for all to see!

  141. Would not a better experiment be to add only a miniscule amount
    of N2 and O2 (80-20) to one bottle reducing the concentration of CO2?

  142. >>Flights canceled as Europe snowed in

    We have had snow on the ground for more than a week now, in NW Europe. Most unprecedented for December in recent times. I’ve not seen this in 20 years, at least.

    .

  143. The thing I find most troublesome about this experiment is this. One bottle is filled with air which is .0388% CO2. The other bottled is filled with CO2. We don’t know how much CO2. But CO2 is denser than air so most likely it would displace most of the air and force it out through the top. So that bottle would be close to 100% CO2. But no one is saying that our atmosphere is in danger of becomming 100% CO2. Scientists typically speak of a doubling of CO2. That would be .077% CO2, or less than 1/1000 of what was used in the experiment. Try the experiment again with .077% CO2 in the second bottle and I predict no measurable difference. Although it seems that there is also no measurable difference if the experiment is simply run carefully even with 100% CO2.

  144. Anybody want to speculate just how much 15 micron wavelength LWIR those lamps put out.

    At the lamp temperature maybe in the 2800K range, the lamp would be emitting something much closer to sunlight, than to “earthlight” at 288K. That spectrum would be much more conducive to CO2 warming, than real earth emissions.
    I would say the experiment was about as controlled as setting off some trinitrotoluene and asserting that organic chemicals are all dangerous.

  145. O2 and N2 in air have no infrared spectrum because they have no dipole moment. H20 has a strong infrared absorption near 2.8u, but the vapor pressure in the experiment would be low. The super strong 4.3u band in CO2 will absorb all the energy in that band. There is also a strong infrared absorption in CO2 at about 15u, which could come into play.

    For the experiment to work, the glass in the bulb would need to be somewhat transparent at 4.3u, or heat up enough to be a bright IR source at 4.3 and 15u. The plastic bottles would also have to absorb rather little in the infrared so that the bottle heating wouldn’t dominate the gas heating. A very thin bottle, like a soda bottle, would have a better chance than the thick ones they seem to be using.

    The experiment could be made to show that CO2 has absorption, but it would take a bit of understanding of Infrared physics, and it’s not much of a surprise that CO2 has infrared absorption bands anyway.

  146. M. Simon (07:58:41) :

    Are the bottles the same thickness?

    I don’t know, but we used the same type of bottle to hopefully eliminate this as a source of confounding. Also, someone mentioned the IR spectrum of the PET, and we didn’t look at that either. Obviously the bottles get involved, but our try with the Moll thermopiles looks though a single bottle and just adds CO2. There is only so much trouble that makes sense for an “experiment” like this.

  147. As a process plant draftsman for a company called Liquid Carbonic many years ago I came to love CO2.

    I later moved onto designing piping for air separation plants, splitting atmospheric air into it’s main components via cryogenics and distillation.

    How have people gotten so stupid, so fast?

    Oh wait, I think I know. It’s due to the dumbing-down and politicization of education and the prevalent MSM attitude that we only know what we’ve been told by our betters. If they don’t talk about it, it didn’t happen.

  148. I keep hearing about this 20 ft rise in oceans so I decided to do some rough calculations:

    Surface area of the oceans is approximately 129,443,838 sq miles (converted from 335,258,000 sq Km) rising 20 feet requires 2.589 trillion cubic feet of water. Is there that much water in the Iceland glaciers?

  149. Completely OT but …
    you all here, Anthony, the moderators and bloggers have a wonderful christmas and keep doing this great job in 2010.
    Thank you all for a lot of valuable information.

  150. I’m sure someone else has pointed this out, but this isn’t even faintly similar to the earth! The greenhouse effect is based on the absorption of longwave IR from a 300k surface. This is shining a ~6000k source that’s shortwave IR and visible light, that CO2 doesn’t substantially absorb!.

    In Trenberth’s words, this is a travesty.

  151. Not only are all scientists to be embarrassed by climategate – but apparently all British people too.

    Nevertheless, interesting to see the BBC reduced to soap commercial tactics – in order to bolster the public’s flagging ‘belief’. ‘And here’s one we washed in a our powder’.

    And when the facts aren’t correct, we’ll make some up.

    How about reporting the new allegations made by King – there’s a bit of news for you. If there are mobile phone intercepts, let’s see, them. Oh – sorry – that would be journalism not evangelism.

    But, I guess that they have already tried saying ‘8/10 scientists say their cats prefer AGW’. So you have to give them points for realizing that scientist credibility had been destroyed by climategate, and a new tactic was required.

    Ugh – at least Canada and Australia aren’t quite so gripped by this madness.

  152. I am beginning to wonder how long it will be before they have to put armed guards around Hadley to defend it from irate British Citizens? http://www.telegraph.co.uk/topics/weather/6822848/Britain-braced-for-6ins-of-snow-as-cold-snap-continues.html

    I know that the Brits that have not left that God awful place are a little slow on the uptake, but sooner or later its got to sink in.

    “Hadley Predicts Unusually Warm Winter” – yeah right buddy. Somehow it looks like you guys are going to run out of salt and sand by mid january.

  153. “”Steve Goddard (07:13:59) :

    There is no question that increasing atmospheric CO2 will cause some increase in temperature. The discussion needs to move to “how much?”””

    My take is that the GHE of CO2 on global temperature is that it is constant. With sufficient CO2 in the atmosphere to make it opaque at the bandwidths specific to CO2 we get about half being radiated back down. As CO2 increases so the optical depth gets lower. Remember CO2 can only intercept some 4% of the total outgoing radiation.
    The total back radiation does not change.

  154. I am amazed that people still use thermocouples/piles. Ever since the first silicon base devices came out in the late 70’s, the first by analog devices I seem to remember, you really do have a range of superb, accurate and well calibrated devices. For those not familiar with them essentially largely irrespective of the voltage applied, within limits, they control the current so that it is proportional to absolute temperature, and work over quite a wide range too. Of course that might be too much magic for a supposedly scientific demonstration.

    Which raises the point that these people do talk down to the public as though they are schoolchildren, I have seen several examples of this, and it isn’t very edifying, especially when the BBC reporter is full of breathless admiration. Analogy is all very well but the public aren’t fools so why should they be treated like that?

    I do not expect them to have more than a basic knowledge of mathematics and indeed statistics and science in general but I dislike the patronising way this is so often done by the BBC. Usually without any pertinent questions being allowed. Or asked by the reporter for that matter.

    Kindest Regards

  155. I’m not sure most of the North American readership would recognise this but the BBC’s ‘Ethical Man’ has a pretty nice and big kitchen compared to the average citizen of the UK, especially for one of such tender years. I doubt you could get a film crew and the guest list into my entire ground floor and wher I live is a lot less expensive than London., where, I suspect, Mr. Rowlatt.

    The BBC clearly pays well throughout the ranks, not just for its so called ‘stars’.

  156. Professor Kilty – thanks for re-running this ‘experiment’.
    I’d have loved to hear the discussions amongst the students while doing this … recalling my past experiences during practicals.

    The sad thing is that so many of the young activists, being mostly arts grads, think this sort of BBC experiment represents true science.
    Personally, I think it was unfit even for a children’s TV programme.

    In case I get distracted by visitors (unlikely when our roads and streets could do duty for ice skating rinks) – thanks, Anthony and all mods for this site of sanity – and a Merry Christmas to all of you and all commenters!

  157. Opalek, (09:39:33) :

    a) swap the thermocouples
    ======================
    All good piping designers know that the sensing element must be placed in the main flow and away from flow disturbances, otherwise you’ll get bad readings.

    “Climate Scientists” seem to not know about fundamental fluid dynamics (let alone the inherent chaotic system of the planet – sheesh). Thank God they’re not designing process plants, as things would be going boom! more often and right in your neighborhood.

  158. I made a formal complaint regarding this programme and received a polite but completely inadequate reply. In common with many others I object to my compulsory licence fee being used in such a way. As you know the BBC has taken a position on AGW and I have yet to watch any show with even semblance of balance. Does anyone know how to take a complaint further?

  159. To cheer you all up, why watch the gravy train pass you by?

    http://www.moneyweek.com/investments/commodities/how-to-profit-from-carbon-trading.aspx

    Ignore the repetition of the conformist viewpoint article and concentrate on the financial advise.
    Some numbers: Carbon trading is at a volume of 126 billion USD in 2008.
    [ http://eureferendum.blogspot.com/2009/12/protecting-big-carbon.html ]
    China gets 66% of the carbon credits emitted under the CDM. This explains why Maurice Strong is in China. So the european public pays China for NOT doing something that emits the dreaded CO2. A very elegant way to fund your communist party, i must say.

    And to rabidfox, the 20ft sea level rise is only a made up number to scare the chicken. If the entirety of Greenland and eastern Antarctica melted that would result in 1.4 meters of sea level rise, that’s what i heard. Iceland is a bit too small to make any difference at all. Do they even have glaciers there?

    Why did the chinese derail COP15 when they’re profiting from Kyoto? Something must be going on behind the scene.

  160. With so many variables possibly varying all at once, and nothing in the way of controls, this experiment is worthless to demonstrate anything. But I did enjoy the surprise of the students in finding out how hard it is to find actual temperatures with thermometers, and how different thermometers indicate different temperatures at the same temperature. This was a good lesson to be learned. That was more than interesting to me when I found that out as a Freshman taking a college chemistry course back in 1953.

    Regardless of the specific heat ratio of carbon dioxide vs air, the amount of carbon dioxide in our atmosphere is so tiny compared to the whole that it couldn’t make a temperature difference that could be detected by any prevalent temperature measuring device. Making the amount twice as high would still make no temperature difference. Did the radiation source emit ultra-violet radiation? No matter, as glass is opaque to ultra-violet radiation. Water vapor alone would overwhelm the effects of carbon dioxide, as the specific heat of water vapor is much greater than the specific heat of carbon dioxide, and there is so much more of it. The more water vapor, the much lower increase in temperature however much heat is added.

  161. I wonder if line voltage was maintained constant during Run 4? A drop of 1volt (which is well inside the range of common variability and would ) would have about the same impact as the observed change.

  162. Steve Oregon (09:41:14) :

    Just as asinine is this video of NOAA cheif Jane Lubchenco doing a little experiment /demonstration in a congressional hearing.

    Hey, that could burn your face off!
    Can you imagine documenting this for posterity?
    Future dad expressions:
    Don’t be such a Lubchenco.
    What are you a Lubchenco?
    I didn’t raise any Lubchencos that lived.

  163. Verifiable truth doesn’t matter to the AGW faithful. Why should it? They have a consensus and they still have a majority of people who believe their dogma (they may not agree that they should pay for it now, but they still believe).

  164. I’m going to have myself some big fun with the BBC dictatorship (BBCD) apparatchiks over this. Global warm mongering will be the last of their worries when I light an inferno of complaints under their asses! Come on everybody in Britain – trash the BBC dictatorship with a deluge of complaints! Action this day and every day!

  165. After watching I am convinced global warming is true, as long as the globe is not a sphere, but shaped like a 2 liter plastic soda bottle, AND humans don’t live on the surface of the planet, but they live inside the planet, AND the planet surface is just something resembling clear plastic.

    More and more, I really do think I live in a world gone mad!

  166. crosspatch @1:25:30

    question – as the CO2 molecule rises, would not the percentage of chance for the photon to be re-emiited towards the earth decrease with height? Say at 5 kilometers, if the photon escaped just below the horizontal, it may not “see” the earth? is this a correct thought process?

    Thanx

  167. crosspatch (01:25:30) : “Experiments like this are silly for many reasons. Most importantly they don’t reflect the natural system. Everyone knows that CO2 absorbs radiation in a few very narrow bands of wavelengths. Any moisture in the air would greatly defeat this, though, and swamp the impact of CO2.”

    Aye, there’s the rub. Water vapor is the strongest greenhouse gas. Unless the water is kept at the exact same temperature in both vessels, the experiment is bilgewater. It’s propaganda, not science.

  168. Cory (06:41:37) : “In a greenhouse the heat absorption that matters is the heat absorbed by the physical structures in the greenhouse, including the glass, and the fact that IR energy doesn’t pass through the glass the way the light energy does.”

    As ScientistForTruth (05:17:40) points out, blocking outgoing IR is of minor importance in a real greenhouse, as demonstrated by constructing one out of material that doesn’t block IR.

    Ian L. McQueen (06:58:15) : “It is my understanding that CO2 does not absorb incoming (solar) short-wavelength IR radiation, but does absorb outgoing (from the earth) long-wavelength IR radiation.”

    CO2 also absorbs some incoming IR; H2O absorbs more. See this graph from (sorry) Wikipedia:

  169. I have jut posted the following as a comment over at the BBC. I live in England.

    I have just watched this video and was quite shocked at how poor the experiment was. Any water in the bottle could make a huge difference.

    I was even more shocked at the blatant untruths that Sir David King put out…

    When asked for a timescale for Greenland and the Antarctic melting he suggested that it would happen within his grandchildren’s lives ! That is preposterous. I bet he can’t find a single climate scientist to support that in any way whatsoever.

    He states as a fact that he knows the objective of the hackers associated with Climategate. We don’t even know whether they were hackers or whether it was a leak.

    He states that the hackers have been accumulating the emails since 1992. There is absolutely no evidence in the public domain for that.

    He states that mobile phone conversations were hacked. This is not true so far as i know.

    He suggests that some kind of agency is responsible for hacking the emails and and says that he will leave it up to us to think about what kind of agency could be responsible. The clear implication is that it is a foreign security agency. He is postulating something based on an assumption that is possibly wrong in the first place.

    How can these comments be allowed to stand without an apology?

    I find it all rather sad that an ex chief scientist and the BBC together put up such a shockingly bad show.

  170. Another quirk with the BBC – I watched a fascinating program about the jetstream, but in the program one meteorologist suggested that global warming moves the jet stream further north. Later in the program the same meteorologist talked about the English floods of 2007 where the jetstream moved unusually far south. I gather that 2007 was a particularly cold year globally [-0.73C] and the implication from the first statement would be that the floods of 2007 were caused by global cooling. That connection was missed out – it was just weather.

    From BBC news at the time :

    “BBC broadcast meteorologist Daniel Corbett said a broad band of low pressure had been sitting across the UK, pushing the jet stream – a ribbon of fast moving air in the upper atmosphere – further south than usual, keeping high pressure and settled weather away from the UK. ”

    Does this make sense? A LOW pressure ‘pushing’ the jetstream. Also I thought it was the jetstream that did all the pushing.

  171. There’s an article written by the reporter who did the show

    http://www.bbc.co.uk/blogs/ethicalman/2009/12/in_praise_of_scepticism.html

    “Obviously, we had to radically cut down the scientists’ presentation to squeeze it into the tight TV time constraints but if you want to dig a bit deeper into the science of global warming the best place to go is the Intergovernmental Panel on Climate Change.”

    Woh, he puts the “scientific” demonstration and the IPCC in the same sentence about science.

    Read the rest, I figure this guy must have suffered some sort of blunt force trauma to the head as a child.

  172. Merry Christmas everyone. The experiment violates the rules of scientific experiment in several ways
    1. Possible biases should have been noted and tried to be eliminated. For example the experiment should have been repeated several times, with the CO2 bottle switched between the bottles.
    2. There was no means of calibrating the amount of CO2, which you try to keep the same as best you could.
    3. As has been pointed out there was no way that anyone in their kitchen “can prove global warming”. The results would have been inconclusive

    THE BIGGEST LIE – HE SAID WE ARE GOING TO PROOVE GLOBAL WARMING RIGHT HERE IN MY KITCHEN!

  173. Don’t pay TV licence. You can watch iPlayer and YouTube TV Shows channel in the UK as well as getting all of Sky TV channels through a computer or Xbox over broadband.

  174. “M. Simon (08:00:26) :
    Al Gore’s Holy Hologram (07:21:11) :,

    And suppose it is not really anonymous to the FSB?”

    That’s what I was hinting at. The FBS via their connections in the Russian Business Alliance would be able to find out who the original uploader through the Turkish proxy is by examining the source’s IP address.

  175. How about a petition on http://petitions.number10.gov.uk/. (It is closed to new petitions over the holidays). It could go along the lines of:

    We believe that the BBC should follow up on its “very unscientific experiment to prove global warming”, available at http://news.bbc.co.uk/1/hi/programmes/newsnight/8418356.stm with a more formal one to check the effect of doubling the level of CO2, which would be higher than almost any estimates of what we are doing or are likely to do in the atmosphere, in a well controlled environment similar to the one that they used.

    We also believe that the BBC should investigate the following areas of Sir David Kings comments for factual accuracy and present their results and if required, an apology:

    (details as per my comment here just a few minutes ago).

    and any other areas which WUWT readers think should be added?

    To make it work, i think it would need its own article here and also a press release to the worlds media. It would be interesting to see how many signatures it might get.

    Excellent suggestion. Do same expts., with and without water. It’s only 2 more bottles, so it shouldn’t be too confusing for some in the audience, though from what we’ve seen I wouldn’t give the “experimenters” the benefit of that doubt.

  177. “It is my understanding that CO2 does not absorb incoming (solar) short-wavelength IR radiation, but does absorb outgoing (from the earth) long-wavelength IR radiation.”

    A molecule will absorb radiation of a given wavelength from any direction, not just from below. The Sun also has quite a bit of long wave IR. Yes, it does also have a lot of shorter IR radiation. But “a lot” is also a relative term. Think of it like this:

    Imagine you are at 10,000 feet altitude and enclosed in a glass bubble. Which long wave radiation are you going to feel more of; warmth from sunlight hitting your face or warmth radiating up from the ground? While the greatest percentage of IR radiating from the Earth’s surface will be in the long wavelengths and the greatest percentage of radiation from the sun may be in the shorter wavelengths, the absolute power of the longer wavelength solar radiation is still much greater than the absolute amount from Earth. If that isn’t clear, imagine 10,000 watts of power from the Sun with 10 watts of that power being long infrared. Now imagine 1 watt of power from the surface of the Earth with 0.5 watts of that power in the long infrared. So 50% of Earth’s radiation in this example is in long IR and only 0.1% of solar radiation is long IR, but we still see more watts of long wave radiation from the Sun than we see from Earth … during the day. At night 100% of the long wave IR is coming from the surface and THAT is where CO2 is going to have its impact … at night or during polar winter. CO2 is going to raise average temperature by increasing the minimum and that is why it has its greatest impact at the poles. They have night for months and it is at night when CO2 impacts temperature change the most by impeding radiation (in a few VERY NARROW wavelengths) to space. The poles are also where the air is driest and CO2 has the greatest relative impact on total impediment to radiation. Water vapor swamps CO2 less at the poles. CO2 would have almost no impact at the equator where water vapor by far swamps CO2 in both the amount of IR absorbed and the band of spectrum that it absorbs.

    So while CO2 could very well cause an increase in global average temperature and a greater increase in annual average temperature at the poles, that change will be mostly an increase of low temperature in winter when there is no sun and the air is very dry, not an increase of high temperature when there is sun and there is more moisture in the air.

  178. Experiments of this type are demonstrated at science fairs etc. all the time and they’re a complete waste of time because as set up they are completely unable to show anything related to the ‘greenhouse effect’.

    First of all the experiment should be done in a cold room, say -20ºC, rather than a bottle a tall open-necked Dewar should be used. A black target containing a thermocouple should be mounted at the bottom of the Dewar, and a calibrated light source (brightness T ~5000ºC) capable of shining the desired light intensity on the target (~200W/m^2). The top of the Dewar should be closed with a plate of a material capable of transmitting both visible and 15μm (e.g. ZnSe). Then you’d have a chance of being relevant, the soda bottle rigs aren’t even close to the ballpark.

  179. Anticlimactic (11:57:31) :
    Does this make sense? A LOW pressure ‘pushing’ the jetstream. Also I thought it was the jetstream that did all the pushing.

    It’s correct, fluid flow is driven by pressure differences.

  180. Merry Christmas everyone. The experiment violates the rules of scientific experiment in several ways

    1. No possible biases were noted and no controls put into place.
    2. The experiment should have been repeated several times, with the CO2 switched between the bottles. Proper controls established
    3. There was no means of calibrating the amount of CO2, (which you could try to keep the same as best you could).
    4. As has been pointed out there was no way that anyone in their kitchen “can prove global warming”. Or even the greenhouse effect of CO2. The results would have been inconclusive

    THE BIGGEST LIE HE SAID STATED WAS – WE ARE GOING TO PROOVE GLOBAL WARMING RIGHT HERE IN MY KITCHEN!

    With very sensitive instruments, and very carefully done experiments, you could confirm that CO2 would trap more heat, and the bottle with more CO2 would get a little warmer, BUT THIS WOULD NOT PROOVE GLOBAL WARMING!

    Merely the undisputed fact of “the greenhouse effect” of CO2

    “Global warming” simply stated is the hypothesis that in our real world, the very small percentage of CO2 we are putting into our atmosphere will cause our planet to warm dangerously.

    VERY SPECIFICALLY AGW PREDICTS THIS CO2 WE ARE PUTTING INTO OUR ATMOSPHERE WILL CAUSE THE PLANET TO HEAT BY 3.5C BY THE END OF THE CENTURY, AT OUR CURRENT RATE OF CO2 ACCUMULATION.

    This can NEVER be proven by any kitchen experiment or any other experiment for that matter, AND AT PRESENT THERE IS NO EVIDENCE THAT OUR PLANET IS WARMING THAT FAST OR INDEED WARMING AT ALL

  181. Gary Hladik (11:47:07) :
    Cory (06:41:37) : “In a greenhouse the heat absorption that matters is the heat absorbed by the physical structures in the greenhouse, including the glass, and the fact that IR energy doesn’t pass through the glass the way the light energy does.”

    As ScientistForTruth (05:17:40) points out, blocking outgoing IR is of minor importance in a real greenhouse, as demonstrated by constructing one out of material that doesn’t block IR.

    Can you point me to a case where someone has done that?

  182. DeNihilist (11:40:12) :
    crosspatch @1:25:30

    question – as the CO2 molecule rises, would not the percentage of chance for the photon to be re-emiited towards the earth decrease with height? Say at 5 kilometers, if the photon escaped just below the horizontal, it may not “see” the earth? is this a correct thought process?

    Not significantly the atmosphere is a very thin skin (~100km vs the earth diameter of ~6000km).

  183. Does this make sense? A LOW pressure ‘pushing’ the jetstream. Also I thought it was the jetstream that did all the pushing.

    Imagine you have a series of pressure systems … H L H L H L, etc, at a given latitude around the planet. Now imagine you have a jet circling the Earth at about that latitude. Remember that air circulates clockwise around H and counter clockwise around L. As the jet approaches the the first H it will be pushed “up” or Northwards to form a sort of “ridge” and as it approaches the low it will be pushed “down” or South to form a sort of “trough” if you were drawing the line on a map. So an area of persistent low pressure at just the right location can push the jet South over the UK while if a high pressure area were in that location, the jet would “ridge” up and around it to the North.

    If you look at a jet stream map, where you see the stream dip down to the South, you will generally find an area of low pressure above it and where you see it bend North, you will find an area of high pressure under the bend. And if you look at the map of the US right now, you will find the entire Western US dominated by high pressure and the jet is pushed so far North as to be off the map. There is practically no jet stream over the US right now.

    Another important factor is the AO and Atlantic Oscillation which is actually a measure of the circumpolar jet. When it is “negative”, the pressure at the pole is weak, the jet is weak and slower and larger. When it is “positive” the pressure at the pole is strong, the jet is faster, and is smaller in diameter.

    The AO is currently the most negative it has been since the 1970’s which means the polar jet is much farther South than it would be of the AO were “positive”.

  184. I’m still waiting for an explanation as to why the temperature DROPPED by 1C over about 10 minutes in the bottle without the CO2 despite the lamp supposedly heating it up. Given the video is clearly a fraud, can any action be taken against the BBC?

  185. A. Erickson,

    Thanks for the alert on the article C&ENews. I’ll read it in the place where I do my serious thinking. I might also flush Rudy Baum down the toilet, at least symbolically.

    I haven’t renewed my ACS membership yet; I’m still trying to decide whether I can support such propaganda.

  186. Peter of Sydney (04:11:43) :

    “I reviewed the video a few times. I’m almost convinced the whole episode was staged. The main reason is I don’t believe so many people can be so stupid not to notice the drop in temperature in the bottle without the CO2 and question it.”

    You and I are the only posters here that have commented on this fact.

    It’s a most obvious fatal error, easily seen and easily understandable.

    It can’t be defended or confused.

    It clearly demonstrates the “rocket scientist” experiment as a laughing stock.

    Although this may be evidence the experiment was fraudulently staged, that argument would complicate the issue and detract from the simple disproof everyone can relate to and understand. Stick your finger a few inches in front of a light bulb and see what happens.

  187. If you look this map you will see the jet stream in Europe dips South. This has Ireland and Scotland above it experiencing cold temperatures and the storm track crossing right through England, the English Channel and Northern France.

  188. Anticlimactic (11:57:31) :
    […]
    “BBC broadcast meteorologist Daniel Corbett said a broad band of low pressure had been sitting across the UK, pushing the jet stream – a ribbon of fast moving air in the upper atmosphere – further south than usual, keeping high pressure and settled weather away from the UK. ”

    The broad band of low pressure must have been sucking on the jet stream. Would be my explanation. Can one say that on air?

  189. Doesn’t anybody know how the argue using logic these days? I thought the Q&A with “Sir Scientist” was funny. He made a point to defend a conspiracy with a truther style conspiracy. “Our conspiracy is smaller than yours!”

    What exactly does the experiment “prove”? Were the earth a corked jar it would be a barren desert. Yet another flawed model.

  191. elmer (09:12:46) : Great your experiment. Now you have to put a global warmer fan in a plastic Bag and blow your truck exhaust gases in it.

  192. And if you look at this map you will very clearly see the storm that is pushing the jet stream so far South. This is likely the same storm that dropped all that snow on Washington DC.

  193. During the Newsnight programme Sir David King was questioning the motives of the ClimateGate hackers. He stated that:

    “They (the hackers?) have been accumulating them (the e-mails) since 1992 and they’ve just released them in the week before Copenhagen.”

    Does he mean that they new Copenhagen would happen a way back in 1992?

    Nigel S (11:18:03) :
    “Better still just stop watching it rots the brain.”
    I feel compelled to watch the BBC for the feeling of nausea that it gives me. LOL

  194. Here is the mythbusters video:

    As you can see, they have four chambers, put one of the controls on the outside, the CO2 seems to be in the center and you can’t tell with the methane and 2nd control.

    The center chambers would obviously be warmer though since they’d be warmed from two chambers adjacent to them, which the outside chambers would only be warmed by one adjacent chamber.

    And that kid (unless it was for theatrical purposes), was recording the temps – I’m sure a brainwashed zealot would do a fine job accurately recording the temps.

  195. From the “Weather is not Climate (but soon to be) dept:
    70-75% of the US is currently covered in snow.
    The Arctic Sea Ice in Greenland is wanting to grow a bridge to Iceland.
    I got that early 70’s feeling.

  196. The deceit does not surprise me. It simply preys on the average persons lmited knowledge of this area of science. We know CO2 is a green house gas which means it absorbs at some wavelengths in the thermal infrared range. CO2 in the atmosphere does warm the earth, no argument. The argument is about how much extra warming comes from an increase from 280 ppm to 560 ppm.

    The aim of the experiment is to show that the high concenrtation CO2 will absorb more energy than air and hence get warmer. Lets do a few calculations. Air at sea level has a density of about 1.29 km/cubic meter. Since the air pressure at sea level is 10,000 kg/sq M that means the entire atmospheric column is equivalent to 10,000/1.29 or 7700 metres of air at sea level pressure. I remember Heinz Hug years ago publishing the absorbance of the CO2 in the atmospheric column at 14 microns was about 2000 abs for 280 ppm. Thats equaivalent to about 0.26 abs per meter at 280 ppm. If the 2nd bottle contained pure CO2 its absorbance would be 0.26 *10^6/280 or 928 abs/meter. That means a 1mm thick layer would absorb around 90% of the 14 micron radiation. Since the bottle is about 100 mm in diameter it is safe to say it would absorb all the 14 micron radiation. That is of course assuming the pastic walls of the vessel did not already do so. Since plastics are good absorbers of infrared its quite likely they would absorb everything anyway.

    Just raising the CO2 level to about 1%, (just breathe into the bottle) means a 100 mm path length would absorb 90% of the 14 micron radiation. What! am I saying a bottle of your exhaled breath is enough to absorb essentially all the 14 micron radiation incident on it? Yes thats right, so maybe a better question would be to ask, if that is so, what difference does it make to double the concentration. More to the point it explains why the experiment does not work for some people. Even the bottle nominally filled with air may have enough CO2 in it to absorb all the 14 micron infrared. Maybe the experiment should be run with 3 bottles, one filled with CO2 free air (put a bit of builders lime [calcium hydroxide] mixed with water in the bottom of the bottle to absorb the CO2), fill the second bottle with exhaled air and fill the third bottle with pure CO2. If the latter 2 both rise about the same amount then ask the question what difference does increasing CO2 make.

    Of course while that would be an experiment in favour of the skeptics it would be just as misleading. Firstly, CO2 absorbs at 2.7 microns, 4 microns and 14 microns . The earth’s surface is not hot enough to radiate significantly at 2.7 and 4 microns only at 14 microns. However the light globe filament is far hotter and would radiate far more energy at 2.7 and 4 than at 14 so we are measuring the impact of different absorption bands. Further, we know the pre industrial level of CO2 is already 1000 times more than necessary to absorb all the 14 micron radiation from Earth. The actual impact depends on the contuous absorption and emission of 14 micron radiation up the atmospheric column which this experiment does not come close to addressing. The fact that CO2 absorbs some infrared wavelengths does not mean AGW is proven. I did an analysis of the impact of CO2 in an article at http://jennifermarohasy.com/blog/2009/03/radical-new-hypothesis-on-the-effect-of-greenhouse-gases/

    Here is a simple experiment you can do along the same lines just for fun. Get a heat lamp, turn it on and put your hand say 50 cm in front of the lamp. Feels warm? Now get a container of water (a fish tank is ideal – parallel sides) and put it between the lamp and you hand. Does it feel as warm? No it feels much colder because water is a good absorber of infrared radiation – ie: it is also a green house gas. What does it mean in relation to proving or disproving AGW? Precisely nothing.

  197. Gary Hladik (11:47:07) got me to thinking after I took a look at the graph that he referenced entitled Solar Radiation Spectrum from Wickedpedia (my misspelling).

    The best way to check out what impact CO2 has on the greenhouse effect in a greenhouse is to have equivalent greenhouse structures and vary the content of the CO2 in the atmosphere of the greenhouses–if one could construct three such greenhouses, simply keep one at ambient concentrations (i.e., ~388 ppm), increase the second’s atmosphere to, say, 1000 ppm (similar to what many greenhouses run to benefit plant production), and the third to, say, 2000 ppm and see what happens. If they were side-by-side and had equivalent internal structures and didn’t interfere with each other with shading, the emprical differences in temperature should give some indication whether CO2 was involved in the heating of the greenhouses or whether the glass comprising the structure walls/roof was the biggest contributing factor.

    Does anyone know whether such an experiment has ever been undertaken?

  198. “A Erickson (11:03:24) :

    OT – Chemical and Engineering News, the weekly publication of the American Chemical Society has a major article on global warming, http://pubs.acs.org/cen/coverstory/87/8751cover.html, which is at least halfway balanced in it’s report. ”

    It’s a good read. What i find striking is: Christy points out that measurements of troposphere temperature is not in sync with what the AGW models predict. Now i would assume an honest modeler to say something like: “Yes, that’s something we still don’t understand, more science needs to be done” but all we hear is “The scpetics are wrong, they believe in myths” from people like Dr. Mann.

    What would be so wrong with admitting that there are areas that are not completely understood? I’m a computer programmer. All good programmers freely admit their errors. No good programmer would ever say “I don’t make errors.” Why can’t the leading scientist of Team Hockey admit that?

    This attitude is a telltale sign.

  199. This experiment is easy,
    Set up the bottles, turn on the light, see which one heats up quicker, call that the bottle with the extra CO2, repeat in front of camera!
    Of course for good measure they should use glass bottles since glass block IR transmission!

  200. I’ve laid an official complaint shown below:

    ‘To whom it may concern,

    I would like to make a complaint about the following video on Newsnight which I feel is intentionally & deceitfully misleading.

    http://news.bbc.co.uk/2/hi/programmes/newsnight/8418356.stm

    At 3.12 in the video there are 2 temperatures before warming:

    Top number: Air with extra CO2 (34.0 C)
    Bottom number: Normal air (35.6 C)

    At 3.36 after both bottles have supposedly been warmed by the electric lamps the numbers now read:

    Top number: Air with extra CO2 (38.7C)
    Bottom number: Normal air (34.6C)

    It seems that even though the bottom number was supposed to have been warmed by the electric lamp it has cooled by 1C!!!

    I find this impossible to believe, & in conclusion have no alternative but to arrive at the conclusion that the lamp was turned off intentionally to promote a fraudulent viewpoint. If the BBC has the standards that it says it does then I suggest they expose this deliberate fraud publicly via their website or on television with an apology. Failure to do so will expose the BBC to be intentionally dishonest & journalistically unreliable. Please be aware that this issue has already appeared in numerous places on the web, & many people consider this yet another example of the BBC shamelessly deserting unbiased journalistic standards to promote a political agenda. What does the BBC think they’re playing at?’

  201. Sue Smith (09:15:29) :

    There is no licence for radio in the UK – and I’ve never had a radio that could pick up the sound from TV, though I don’t have a digital radio.

    Digital radio? Back in the ancient days when all commercial broadcasts were analog, with the standard US frequency groupings (AM and FM for audio, VHF and UHF channels for TV), places like Radio Shack sold audio receivers for all four bands, battery-powered transistorized sometimes-handheld devices. A VHF-only one could be for in a city with VHF TV broadcasts (VHF doesn’t travel that far), you could listen to your soap operas or a baseball game while doing other things. You could have all four bands, some also had shortwave. Keep track of what’s on the TV (like news) without being stuck at a TV.

    I must assume if they never made ones for UK use, it was only because the scarcity of BBC channels led companies to assume there would be no market.

    Now that here in the US the TV “over the air” broadcasts are in digital, new equipment is needed to decode and extract the audio. Between TV’s being relatively cheap and portable, and with alternate technologies like cellphone and laptop TV, the market might not be there except for a few enthusiasts.

    Thanks to the link provided above I can see the BBC has their expected sensibilities about the matter.

    From here:
    If you use your digital set-top box to produce sounds only (you don’t use it to display programmes), then you don’t need a TV Licence.

    So if you are seeing any live video at all on anything then you need a license, but if the device is only extracting the audio (like for a speaker system) then you don’t need a license. Thus such a radio should be fine.

    Also, from here:
    You’re entitled to a 50% reduction in your TV Licence fee, if you’re certified as either blind or severely sight impaired.

    If you’re not seeing any live video at all but you are listening to the sound, they only charge half.

    Doesn’t that make perfect sense?

    I’m not seeing this listed on the site… How much do they charge if you are blind and deaf?

  202. Wow what a whizz kid that Jane chubchenko is.

    So those sea shells adn corral reefs would grow just fine in ordinary tapwater; isn’t that special.

    It would have been nice if she had used actual sea water taken from near say a coral reefr and put her blue dye into that to show it going yellow when she cooled the blazes out of it with dry ice. That’s the first time I’ve seen dry ice evaporate without giving off a cloud.

    Having a bit of coral in the seawater so we could watch it turn up its toes would have been a nice touch.

    Hey so long as the New Zealand green lipped mussels still grow, I don’t care if they turn crimson in the process; I prefer the pink ones anyway.

  203. DirkH (13:31:00) referenced an article by American Chem Society and I read it to the point where it said:

    “But water vapor is not considered a forcing. Nor is it assigned a global-warming potential, because it has a relatively short residence time of about 10 days in the atmosphere, compared with a century or longer for CO2.”

    That is a bunch of baloney. What MATTERS is the abundance, not how long any particular molecule or portion of the entire masss has remained in the atmosphere. Atoms that remain in the atmosphere don’t progressively become better at absorption just because of their time there. Again, what MATTERS is the abundance of the gas. Residence time has nothing to do with it.

    My gosh, who’s responsible for that idiocy?

    Water ranges from 0 to 4% of the atmosphere–that’s up to 40,000 ppm, or an averge of 20,000 ppm! Compare that with the average of CO2 at 388 ppm, and water is about 50 times more abundant. And since water is known to be a more effective greenhouse gas than CO2, ignoring it and giving the excuse that it goes in and out of the atmosphere faster than CO2 is the biggest distortion I’ve heard yet.

    I’m betting they ran the models with a proper weighting for water and they said “Oops… nothing to see here folks! Move along now…” And since that would have blown their whole argument, they decided to ignore it completely and used an illogical excuse.

    These people get grants??

  204. MERRY CHRISTMAS to all at WUWT. You guys are the greatest!! I look forward to even more and better in 2010. Thank you for all you do.

    [Merry Christmas from Everyone at WUWT to you and all of you out there. ~ Everyone]

  205. Response to:

    Alvin (13:11:47) :

    “388 ppm = 38/1,000,000 = 0.000388 correct?”

    Yes, correct! Which is 0.0388%

    You left out an “8” on the first equation; otherwise that’s correct.

  206. God – I am beginning to hate the BBC so much!

    The broadcasting of constant propaganda like this is an utter disgrace. The BBC is supposed – but has long since ceased – to be an impartial organisation. It has reached the point where I no longer believe anything they say, unless I have independent verification.

    I am particularly annoyed that the one person in the room with sufficient commonsense to continue to question the mantra, even at the end of this “experiment”, got the brush off from the propagandist.

    And what is this utter carp about mobile phone hacking???

  207. @ DirkH (13:31:00) :

    There are no coding errors. Those are not bugs, they are features. If the program does not yield the desired result for the data that was inputed, it indicates the failure to properly condition the data before it was inputted.

    Oh, and as a proper programmer, one should make sure to archive the list of all the individual data conditioning adjustments with the original data, so you can keep track of all of it at once. Even though you will only ever need the conditioned data as that works with the program.

  208. Phil. (12:24:47) : ..to show anything related to the ‘greenhouse effect’.

    First of all the experiment should be done in a cold room, say -20ºC, rather than a bottle a tall open-necked Dewar should be used. A black target containing a thermocouple should be mounted at the bottom of the Dewar, and a calibrated light source (brightness T ~5000ºC) capable of shining the desired light intensity on the target (~200W/m^2). The top of the Dewar should be closed with a plate of a material capable of transmitting both visible and 15μm (e.g. ZnSe). Then you’d have a chance of being relevant, the soda bottle rigs aren’t even close to the ballpark

    It would be great if we got all the BBC guys into a cold room at -20C to “prove Global Warming”. Great news to have them treated for frostbite for the cause of their faith.

    To “show anything related to the ‘greenhouse effect’” you presumably need not one dewar but two. Wont you have problems with calibrating the amount of CO2 to keep the experiment fair? and the distance of the two from the light source?

    In any case all it might demonstrate, perhaps dubiously, would be “the greenhouse effect” of CO2.

    It would not “prove Global Warming” as that idiot said it would.

    Which SPECIFICALLY IS The PREDICTION THAT WE WILL WARM BY 3.5C BY THE END OF THE CENTURY.

  209. WUWT

    Guys – All this politics and schadenfreude at ClimateGate and the Copenhagen fiasco are all very well – but can we now increase the proportion of threads directly on the science of oceans, atmospheres, climate trends, interesting published articles etc.? Getting a bit nostalgic for the science at WUWT. (On climate its the best place to find it.)

    A VHF-only one could be for in a city with VHF TV broadcasts ([*]VHF doesn’t travel that far)

    Compared to anything else in particular? Or versus MW broadcasts (“AM Radio” here in the US) or SW?

    Have you seen the VHF and UHF propagation charts (field strength charts) on the U.S. FCC website? “VHF-UHF Field Strength Measurements”

    Short story is: UHF has the ‘range handicap’ of the two bands (VHF vs UHF); when it comes to rough terrain low-band VHF will ‘diffract’ with lower losses over hills, etc allowing prpopagation slightly beyond waht is classically called line-of-sight.

    “At least halfway balanced” is pretty thin gruel, when it starts out with this kind of setup:

    Mainstream climate scientists maintain that man-made global warming is happening. But a few global-warming skeptics argue that there is still a lot of guesswork in how those scientists came to that conclusion.

    That is a bunch of baloney. […]”

    Yes, they do have funny terms with their definitions of forcings and feedbacks.

    Personally, i’m just trying to find out whether the computer models have gotten better over time, to the point where they incorporate e.g. the biosphere or clouds. Oh, and ocean currents.

    I also found RealClimate’s take on the discrepancy between Christy and the computer models on wikipedia. Something that indicates Christy had a mistake in his data set. Why the article still mentions it as a point of contention i don’t know, according to RealClimate (per wikipedia) it’s been solved.

    Harsh envirinments; did you consider survival of the temp sensor in harsh environments?

    A generic laboratory theromocouple will work -200 + 400 deg whereas your silicon device not so much … and the silicon needs care and feeding like power, and a transducer to convert that voltage to a TEMP reading (much like a thermocouple) ..

    Also, JUST as advances have ocurred in ‘silicon’ processes SO TO have advances progressed in other device and material types as used for temperature measurement e.g. Thermisotrs and RTDs.

  215. I learned at school that chemical reactions are either exothermic (give out heat) or endothermic (absorb heat).
    Either way, this is a fundamental flaw in this so-called experiment as one bottle has a chemical reaction going on in it and the other does not.

    Happy Christmas to all

  216. The reporter, Justin Rowlatt, seems to fancy himself as an “ethical man”. The program resulted in skeptical views being transformed into belief; in one case an individual claiming that from what he saw he now believes GW to be a “fact”.

    Here’s an email addy: newsnight@bbc.co.uk
    that might work to contact him, found at
    http://www.bbc.co.uk/blogs/newsnight/ethical_man_justin_rowlatt/

    Although I believe this “very unscientific” experiment should be exposed as being one, in the public domain, reaching as many people as possible,
    instead of complaining to BBC about it, confronting Justin may prove interesting. But then the “ethical man” likely is already aware of it, and just doesn’t care.

  217. Wow!

    What a paper! This is the type of thing that I have been searching for to send to my local newspaper. Something written in plain English, yet allows both sides, and even more important, lets the reader in on how the science is not settled, but evolving even quicker!

    Thanx for the lead.

  218. Where is the science in giving selected critic “mulled wine and minced pie?”

    They are sloshed, for one, and who would criticize someone who just gave you pie?

  219. This is what I have written to Justin Rowlatt
    Justin Rowlatt – I demand an apology from you. Please apologise for that deceptive program you did called “Putting the science of global warming to the test”.

    In that you said “WE ARE GOING TO PROOVE GLOBAL WARMING RIGHT HERE IN MY KITCHEN!” What a big lie!

    1. What you did was a very faulty experiment to try and “prove” or demonstrate the “greenhouse effect” of CO2.

    2. The experiment was faulty. It had no hope of demonstrating such a thing, in the way it was done. That the temperature of the CO2 bottle was higher than the one with less CO2 was a matter of accident, due to probably many other causes, other than the greenhouse effect of CO2, which cannot be demonstrated in ones kitchen.

    3. Even if you do a very sophisticated experiment in a cold room with very accurate instruments, at most what you might demonstrate is the NOT DISPUTED greenhouse effect of CO2.

    4. Demonstrating the greenhouse effect of CO2 DOES NOT “prove Global Warming”

    “Global warming” simply stated is the hypothesis that in our real world, the very small percentage of CO2 we are putting into our atmosphere will cause our planet to warm dangerously.

    VERY SPECIFICALLY AGW PREDICTS THIS CO2 WE ARE PUTTING INTO OUR ATMOSPHERE WILL CAUSE THE PLANET TO HEAT BY 3.5C BY THE END OF THE CENTURY, AT OUR CURRENT RATE OF CO2 ACCUMULATION.

    This can NEVER be proven by any kitchen experiment or any other experiment for that matter, AND AT PRESENT THERE IS NO EVIDENCE THAT OUR PLANET IS WARMING THAT FAST OR INDEED WARMING AT ALL

    Your talk was deceptive to an uninformed audience, who were even more uninformed than you and misled them.

    Please therefore apologise and issue a correction for that program.

  220. _Jim (14:37:10) :

    (*How _do_ these myths get started?)

    Because most people don’t actually understand the propagation of electromagnetic radiation. In free space, there is NO dependence upon frequency, and I’ll be willing to bet even most engineers that dabble in the arts think there is. It is not a surprise, however, since a frequency term is always include in propagation equations (the Friis transmission equation includes a frequency (wavelength) term in it). However, the term is actually the result of dimensioning at the antenna, and is not actually indicative of the transmission channel itself. EM simply obeys a 1/R^2 relationship that results from the area on the surface of a sphere.

    That said, as you noted, there are differences in an atmosphere, typically related to diffraction (and a few other effects). At higher frequencies, much higher, various molecules in the atmosphere will begin to absorb RF energy to the point at which transmission over any useful length is nearly impossible. This is why satellite crosslinks are typically 30 GHz or 60 GHz (approximately): you can’t detect them from the ground.

    Mark

  221. Seeing that the Oceans have at least three orders of magnitude more influence on our climate than the atmosphere them this was the wrong experiment anyway.
    Ignore just how poorly conducted, laughably arranged or pop-cultured this travesty was, it was not only innefficient but irrelevant!
    Take two equally sized bottles of volumetrically equivalent aqueous solutions at STP (let’s pretend at least), subject them to ‘equal’ radiant heat sources for the same amount of time and (this may be important or not) capture the atmospheric state above them.
    I suggest that bottle A contains glacier filtered dihydrogen monoxide while the other contains a real-ale(any will do actually)
    Ask yourself this, is warm beer tastier than cold beer?
    If you can’t immediately answer the question just repeat the experiment. The answer will come, believe me!

    Ha! I think that is it. One jar has local air, the other has local air plus the contents of a CO2 charger, like that used for whipped cream dispensers or pellet guns. So the latter has more pressure, and will heat up faster.

    What else could it be?

  230. And it is a good thing there isn’t a strong jet or this storm looks like it would have the potential to be the mother of all nor’easters if it did. It formed in the right place. Had there been a strong jet pushing it to the East coast, it would be “katie bar the door”.

  231. Steve Goddard (07:13:59) :

    There is no question that increasing atmospheric CO2 will cause some increase in temperature. The discussion needs to move to “how much?”

    Really?

  232. What would happen to the M.T. reading if the reflector was turned away from the heat source? I mean if AGW due to CO2 in a bottle it shouldn’t really matter which way the M.T. was pointing, and especially if you want to delete the heat source as a factor of uncertainty.

    To properly make this experiment you need a proper light source, i.e. a “sun lamp”, a glass bottle of at least acceptable optical quality, water without at least too much chlorine left.

    The light source has to be at a certain strength and then distance so that it mimics the amount of candela that the area of the glass bottle would get in full sun light. But of course if you really have to do stuff within the hour you need to move it closer, but don’t hit that light switch before you start stuff, because you need two temperature readings.

    One T for the air, and one T for the water. You need the start temperature for both so you can account for both. Warmer water means warmer air after all.

    You also need other stuff, a way to measure the different concentrations in the bottles atmospheres, and preferably in the water as well.

    The surface the bottles are standing on has to be neutral, or the same for every bottle, i.e. if there’s a cabin under one bottle…. you might need that water temp after all.

    Now try that less then stellar rocket science of NASA on for real.

    But of course, what you’ll be doing is not actually confirming AGW, but that a ‘seltzer tab will raise CO2 levels plus other additives that makes up the tab, and water vapor, and not to forget pressure, which will lead to a bit higher temperature even in a room devoid of light which is because there is some energy released when the zelts tab reacts with water, and of course adding to the pressure.

    You can try NASAs silly experiment but exchange the CO2 for Oxygen, and see which one is the more competent AGW molecule according to the common AGW logic, just try it at your own risk, but please do not tell EPA. Heh you can up the nitrogen, or argon, or what ever, especially as long as you put the cap on, just like NASA sciency, to up the pressure too.

    Oh, and merry christmas all.

  233. My email to Justin:

    “It should be very embarrassing for you to realize that the bottle of air in the experiment shown was cooler at the end of the experiment than at the start. Clearly this invalidated the experiment.

    Hold your finger a few inches from a light bulb and see what happens.

    Had a proper and representative experiment of the atmosphere been done using 375ppm CO2 in the one bottle and 275ppm CO2 in the other, the temperature rise would have at best registered a couple tenths of a degree, and certainly not a “convincing” four degree increase.

    At least one of the skeptics on your show appeared to be convinced by what he saw, enough to declare global warming to be a “fact”.

    The ethical and smart thing for you to do would be to publically acknowledge these facts and apologize for the very unprofessional episode and to all who may have been deceived.”

    Not really, but theoretically in a two dimensional static world.
    In the real world, it is not useful or realistic to attempt to argue there will be no increase in temp with increased CO2.

  235. The amount called “some increase” needs to be statistically significant. Period. Or else the results confirm the NULL hypothesis and no discussion is needed or warrented. So the question does NOT need to be “how much”, but rather is it “statistically significant”. If this question were on a Statistics 101 exam, would you have passed it?

    Right – I had that EXACT discussion with an otherwise technically competent radio/RF guy just the previous week; had similar discussion with a dept lead and mgmt type over his dept a few months back re: FCC/EMI rad from ‘a box’ when the discussion turned to suppressing the energy internally and one of them piped up: “… and the added distance to the openings will give us additional attenuation”. The ‘box’ in this case is a conductive on all six sides, basically a large waveguide, and ‘leaks’ near a couple I/O ports and connector blocks and distance in that case especially makes _little_ difference (literally: guided waves internal to the box)!

  241. Another reference to the Mythbusters video, a commenter noticed this:

    I would love to know what the gas concentrations actually were. At one point the computers shows 7.3% !!! That’s 73000ppm 208 times above normal.

  242. Here’s a way I thought of to have invalidated that experiment. Tell that lady “top scientist” (is this what the UK is reduced to?), hey do you mind repeated that experiment usind those same two bottles, but this time do not fill the other one with CO2. When the bottles heat up differently – well then we have a problem dont you think?

  243. Alvin (18:08:49) : I’m sorry but I dont think that makes any sense. Where do you arrive at ppm from? That experiment was just junk, top to bottom

  244. This reminds so much of the cold fusion days. At that time I was following the attempts at replication on the old netnews physics groups ( the predecessor of blogs if you will) by a number of experimenters. One experimenter was a specialist in calorimetry measurements at Fermilab.

    The experimental issues with calorimetry were stunning.

    The difference between cold fusion and warm climate is that the CF claim could be attempted independently of a single data source. Nobody could replicate, and the general belief was that Pons and Fleischmann messed up the calorimetry – something they did not great deal of history with.

    Is calorimetry the equivalent of statistics?

    The alarmists don’t believe the Hokey Shtick was debunked. They feel that McIntyre’s analysis is bogus.

  247. Crosspatch at 12:23
    In my mind your explanation raises two questions:

    “At night 100% of the long wave IR is coming from the surface and THAT is where CO2 is going to have its impact … at night or during polar winter. CO2 is going to raise average temperature by increasing the minimum and that is why it has its greatest impact at the poles.

    1) During the polar winter, when the sun is not shining on the poles, doesn’t the long wave IR reduce accordingly in watts at the poles? I believe the Earths IR radiation varies directly with amount of sunlight (and thus would be a local effect). Or do we assume a global uniform IR radiation from the earth?

    “The poles are also where the air is driest and CO2 has the greatest relative impact on total impediment to radiation. Water vapor swamps CO2 less at the poles. CO2 would have almost no impact at the equator where water vapor by far swamps CO2 in both the amount of IR absorbed and the band of spectrum that it absorbs.”

    2) So here we know that Water Vapor is not uniformly distributed about the earths surface, in fact it stays relatively local. Is C02 uniformly distributed about the earths surface (i.e. it is everywhere 388 ppm or close to it)? And if so, then how would man made CO2 (which is generated in a highly localized fashion – more so than water vapor) get uniformly distributed?

    I see a problem here.

  248. DirkH: If that is halfway balanced I’d hate to see an unbalanced report.

    The AGW case is being made by people who must now be under suspicion of incompetence and lack of objectivity at least, fraud at worst. You can believe nothing they say now or have said until until their work has been thoroughly examined by a “red team”. Any attempt to hide or lose raw data and methods is now prima faeci evidence of wrongdoing. They are providing plenty of this.

  249. The answer to number 2 in my 19:24 post appears to be C02 is not uniformly distributed (at least in the mid-tropospheric) and appears to be concentrated in west to east circulating bands.

    http://www.jpl.nasa.gov/news/news.cfm?release=2009-196

    Given this, the overall question still remains, if no sunlight and not much more CO2 (at least due to man) at poles – warming (if any) during polar winter is due to what?

  250. Similar propaganda? What’s our response to the current scare-tactic article in the New Yorker about Adelie penguins?

    Because most people don’t actually understand the propagation of electromagnetic radiation.

    *ahem*

    Or… If you would care to peruse the Wikipedia UHF article where it discusses the introduction of UHF television into the United States, you will note that the relatively few VHF stations were being made to operate at relatively low power by the FCC to avoid interference problems. Meanwhile with the far more numerous UHF stations that were being introduced, they were allowed to operate at much higher power.

    Limits on UHF effective radiated power, originally very restrictive, were relaxed. A UHF TV station could be licensed for up to five megawatts of carrier power, unlike VHF TV stations, which were limited to 100 – 316 kilowatts of carrier power depending on their channel.

    Yup, you read that right. UHF could broadcast from between about 19 times to 50 times the power that a VHF station could.

    So UHF channels traveled much farther. And VHF was known for not transmitting all that far.

    If you read down in the “Digital Television” section, or at this linked larger piece, you will also note that, well, VHF just doesn’t seem well suited for DTV, especially the low band (channels 2-6). Sure, at the same power a VHF signal will propagate further, but it will propagate junk.

    Also, during the digital transition, stations obtained a second frequency that they used for their digital broadcast, the signal causes receivers to report their original channel number. UHF stations that were assigned VHF channels have run into problems. I can confirm that here, in Central PA, using an indoor antenna, where analog UHF channels came in about equally well from both the Harrisburg/York and the Wilkes-Barre/Scranton markets, now that the transition has passed, formerly UHF stations that moved to VHF are now gone, we are not picking them up anymore. One Harrisburg station, WHP-TV 21, had gone to VHF 4, was lost, switched back to UHF 21, and now we receive it again.

    So, not only are UHF stations traveling further, UHF is becoming the broadcast band of choice for digital with “Superior!” VHF being practically abandoned.

    I hope this issue is now taken care of.

    And A Very Merry Christmas To You Too!

    Bzzzt! Wrong!!

    Facts, field tests do not bear this out (see my previos post for context), contrary to repeated assertions and Wikipedia cites. Sorry. (Bear in mind wikipedia is sorely lacking in some subject material.)

    Analysis: It appears you misinterpret, (twist?) the meaning, the intent of other’s material, or fail to understand it, or fail to understand the nature in which various ‘shortcomings’ should be understood (perhaps you lack context in the radio art, understanding the terminology which has a loooong history or legacy).

    Kindly review the documentation at the link I supplied earlier and review the charts in that document for the support of my assertions (you will find little support for your ‘theory’ since ground conductivity/loss plays the BIGGEST part in out and out ‘range’ or distance in VHF vs UHF matchup, and losses are simply *higher* for the higher frequencies. Fact.)

    For decades UHF television floundered; the receiving equipment using only a simple passive diode mixer was not on a par with the performance of ‘active’ devices (even early RF amplifier tubes like the 6AK5) used in VHF tuners. Things have been different for a couple decades now, though the transition of the Zenith “M1” tuner for instance.

    There are other issues to consider, but that was not the thrust of your first post on the subject, nor has it been supported in this post exc by repeated assertion.

    Give it up now; you have met a ‘superior force’ who lived that era and participated in it from the technology side of things.

    Have a Merry Christmas too.

  254. The few skeptics in the BBC story stood no chance making arguments. Not a physicist among them. So how much CO2 is in the bottle? Many magnitudes larger than current earth levels and it only warmed a few degrees? So how much should a few more PPM to warm a degree on earth?

    Stupid experiment that a good high school student should be able to put down. Where’s Richard Feynman when you need him?

  255. Stefan (01:49:19) :

    I’m glad this is getting attention.

    I’d posted about that program just after it was broadcast, as I was amazed by the allegations about “agencies” and “mobile phones”. Another WUWT reader replied to tell me he’d also just watched it and that King had said no such thing.

    It seems different people can hear and see different things, eh?

    I recall that reply well. I determined to look (but forgot). Looking now (and suppressing my gag / shout reflex), he did claim exactly that. He even prefaced it with “let me be the first to make this allegation” FFS!

    “There is none so deaf as those that will not listen” (to paraphrase).

    As for the ‘science’ this is way below anything even ‘blue peter’ did in my day. Poor to pathetic I’d call it. I would seriously love to see a real experiment, one that I could believe in, and I don’t think it would cost more than a tiny fraction of the $80 billion so far spent. If it proved AGW, I’d change my mind right away and sign up to fixing ‘climate change’. Until then, I am sceptical.

  256. TomTurner in SF (19:43:35) :

    What’s our response to the current scare-tactic article in the New Yorker about Adelie penguins? The article claims that significant warming on the Antarctic peninsula has caused and is causing a decline in Adelie penguins?

    By now, who cares what the AGW propaganda machine says? If someone asks you about it, just tell them that the AGW claims, including the ipcc’s own critical “scientific” predictions, have so far always turned out to be either be wrong or irrelevant to the AGW case.

    Use Polar Bear numbers example, or whatever else you choose. Try mentioning the “lack of the ‘hot spot'” to turn really the tables. They haven’t got anything right yet! And the people you will be addressing likely have no idea as to what the “hot spot” even is. If you know it and its importance as an AGW prediction, they’re dead in the water.

    Tell them that the ipcc and the elite Climate Scientists are simply not doing real Science, if you know you can back it up. It’s actually pretty easy – you might tell them about Anthony’s work. Why would any true Scientist wanting to discover what surface atmospheric temperatures are doing then not check a single freaking thermometer or their sitings?

    Tell them you’re getting tired of chasing wild geese. Try asking anyone who asks you, to get the “scientific” article and go over it themselves to see what they think, then give it to you.

    By now there is no reason to worry about any of their claims. I’m not going to waste my time by even looking at their slide show.

    All they are doing with these alleged harm or disaster stories is trying to get another out without proving it, then repeat the tactic using another false story.

  257. >I know that the Brits that have not left that God awful place are a little slow on the >uptake, but sooner or later its got to sink in.

    Thank you ShrNfr – very well said

    I saw a little of ‘ethical man’ on the TV over in the US. He was flying around the US taking people to task over their carbon footprints, dietary habits, hair style preferences, and so on, like a a pompous, unfunny, Brit version of Borat. Even in my decidedly tree-hugging household he was regarded by all who saw him as ‘a pillock’.

  258. How about some simple experiments to show that plants actually require CO2 and they actually do better at higher concentrations?

    Since we all know that plants are food and we already have too many starving in the world – who in their right mind would even consider reducing the amount of CO2 in the atmosphere – that is called genocide!

    I have been looking for an experiment showing plants sensitivity to CO2.

    This may be a simple experiment for the masses to easily do?

  259. I expect an apology and a retraction by the BCC about the fraudulent video. However, I doubt they will have the honesty to do it as they have proven time and time again they are not interested in establishing the truth.

  260. Roger Knights (17:19:22) :

    Why did the chinese derail COP15 when they’re profiting from Kyoto? Something must be going on behind the scene.

    Another poster here suggested that they don’t want their largest debtor, the US, getting deeper into a hole.

    What I also got was that the Chinese loved Kyoto because it didn’t require them to do anything. They could use as much fossil fuel as possible. They also expected that they would get subsidized somehow, even from businesses moving to China to escape Kyoto.

    The problem developed, imo, when the “basic structure” of Kyoto was going to be changed so that the Chinese were going to have to limit their use of fossil fuel.

  261. Re my comment on 24/12 (02:43:28), marc (05:42:05) then corrected:Arthur Glass (03:47:45) , who had written:
    “??? Surely the latter number is correct. 0.0388 would be 388 parts per 10,000 –two orders of magnitude difference!”
    Not if you are talking about percentages. For instance, 0.01 = 1%, so 0.000388 (388 ppmv) = 0.0388%.
    Yes, marc is absolutely right. It’s really a bit of a worry when GW respondents like Arthur Glass don’t know that 388 ppmv of CO2 is the same as 0.0388% in the atmosphere. How come? The answer: 388 divide by 10^6 multiply (for %) by 10^2. Worth mentioning here that total atmospheric methane is 1600 ppbv, or 1.6 ppmv, which is only 0.000016%. A really tiny amount, but the warmers go bananas over it!

  262. Keith Guy:
    0.000388 ppm= 0.0388%

    The sound you hear is a voluble slap against my red (with embarassment forehead!)

    That is just the sort of careless error that got me C’s and D’s in math back in the days of Pythagoras and Euclid.

    Thanks for the good-natured correction.

  263. “A really tiny amount, but the warmers go bananas over it!”

    And apples and oranges, too! Without that minisculum of CO2 in the atmosphere, there would be no biosphere as we know it (vagrant bacteria don’t count).

  264. Kevin Kilty sounds like an excellent teacher, just the sort one would hope to find on, say, PBS (don’t hold your breath). His passion for the beauty and integrity of scientific method is contagious.

  265. A Ericson (11:03:24),

    From the editorial:

    …water vapor is not considered a forcing. Nor is it assigned a global-warming potential, because it has a relatively short residence time of about 10 days in the atmosphere, compared with a century or longer for CO2.

    The best that can be said for that slanted editorial is that it didn’t refer to drowning polar bears or increasing hurricanes. But when they can’t get simple facts correct, it’s hard to give them any credibility. For example, their unequivocal statement that CO2 remains in the atmosphere for a century or longer is a major error, contradicting numerous peer reviewed studies. click

    This is an important question. If CO2 persistence is a century or more, then as CO2 rises fast the temperature will rise fast. But that isn’t happening. As CO2 continues to rise, the temperature has fallen for nearly a decade.

    It’s clear the Editorial writer spent lots of time with Michael Mann, taking Mann’s view on most everything.

    I give the editorial three Harrops.

  266. Are we being a bit small-minded to attack the BBC for this? The experiment is a very simple one, climate science does not exactly rest upon it. There are positives from this from a climate skeptic viewpoint:
    – the discussion viewed several skeptical opinions albeit not particularly scientific ones
    – science and the scientific method were taken seriously, made to look cool.
    – in modern society not least the UK there is an anti-science body of opinion and in attacking AGW and everything connected to it we should take care not to play into the hands of anti-science.

    Attack the wrong enemy and results can be unexpected and disastrous (look at history, e.g. medieval Russia defeats Kazan (who were holding the Mongols in check) then a few decades later Mongols destroy Russia and half of Europe.)

  267. from WUWT reader Bryan C of the UK. Here’s an excerpt:

    Dear Anthony

    Here’s something I found shocking and that you don’t see every day: the British government’s former chief scientific adviser Professor Sir David King flagrantly lying on national television.

    It’s tempting to ask, where has Bryan C been all these years?

    It’s also tempting to become a cynic rather than a sceptic in these troubled times.

    When approaching a paper regarding the environment I am now a cynic in that I struggle to understand the science in order to expose the fraud that usually accompanies such things.

    Like many of you I read papers that are released via the tabloid science magazines that these days masquerade as peer reviewed journals.

    I was doing what all sceptics do and was talking to a catastrophist who blamed global warming on the infestation of Tasmania waters by the long-spined sea urchin.

    Cynicism drove me to research.

    It has nothing to do with global warming but here you need to understand where I’m coming from.

    I could not have found the real cause without the research of a real scientist and with that I will leave you with the answer. They are not all frauds.

    http://eprints.utas.edu.au/6290/

  268. @_Jim (20:52:28) :

    There is nothing to concede as you are arguing the wrong thing.

    You have reduced this to a classic argument between a theoretician and an engineer. You may have the science with the studies that says it is so, I have the real world where it says you are still wrong.

    It is not in dispute that longer wavelengths generally travel farther than shorter wavelengths of the same energy under normal terrestrial conditions. This is manifested in sound waves. This is why VLF and even lower frequencies are used for submarine communications, with ULF being also used to communicate with underground mines.

    But we are not talking about the same energy. Here in the US the FCC is limiting VHF broadcasts to lower power transmissions than is allowed for UHF. Thus the distances from the transmitter at which you can get a usable signal are greater for UHF than VHF, simply because UHF TV broadcasts are done using more power.

    Thus, out here in reality, as has been noted for ages, VHF broadcasts are found in large metropolitan areas, while UHF is used for much-larger areas.

    Here in the real-world US of A, due to an artificial constraint imposed by the FCC, VHF doesn’t travel that far.

    How did the “myth” get started? It exists because it is a practical fact.

    Reality trumps theory. Deal with it.

    Oh, your “documentation” is a Xeroxed 1966 report, scanned as a collection of images and crammed into pdf, concerning the development of terrain adjustments to be applied to existing propagation curves. (BTW not everyone has broadband, dang thing took over twenty minutes to download.) As it is not concerned with nor makes any judgments concerning the merits of VHF vs UHF in the text, apparently I was to decipher this information from the myriad near-illegible graphs. What is curious is how in a later post you mention the inadequacy of UHF receivers vs VHF at the time this was researched, and yet this ancient document is presented as something definitive and relevant in this more modern age. Interesting.

    Meanwhile, post-digital transition, VHF is still being abandoned in favor of UHF, with the lower VHF band especially noted for its inadequacy. Might not be much longer before the argument is moot.

  269. its funny how they did not show the results of this experiment. the reason they did not show the results is because the container filled with C02 will end up cooler than the one filled with normal air. why? because C02 is more dense than air. every element has a certain density and a reflectivity of light based on that density. that is why metal is opaque and air is not. glass being the exception for visible light but it still reflects almost all inferred light. C02 is dense enough were it hugs the ground therefore rendering it incapable of being a green house gas because it is not suspended it the atmosphere. the other reason is because at its density C02 reflects more light than it lets through, there fore cooling the planet not warming it making it an “ice house gas” not a green house gas. plus C02 is plant food so that disproves them calling it a pollutant. There i have thus dis proven the entire global warming theory, and i am only 15.

  270. Comments on the Chemical & Engineering News article, “Global Warming and Climate Change,” of Dec. 21, 2009

    1. The NAS findings on Mann’s data.

    “Mann’s data held up to scrutiny by a National Academy of Sciences review panel, which “acquitted” the data but made specific suggestions on how scientists should improve temperature reconstructions.”

    This is too lenient a summary, perhaps based on Chairman North’s ex officio remarks. The data was not exactly acquitted, because the NAS accepted all of McIntyre’s corrections.

    2. The Hockey Stick.

    Caption: “The hockey stick data have since been substantiated with similar temperature reconstructions by other groups.”

    “Substantiated” is too strong an endorsement of the hockey stick. Check out Moncton’s summary of the substantiation attempts in his article, “Hockey Stick? What hockey Stick,” at http://scienceandpublicpolicy.org/monckton/what_hockey_stick.html

    3. “Global Warming Antagonists”

    That isn’t a bad term. But better are “Catastrophe Contrarians” or “Climate Catastrophe Contrarians”

    4. Recovery from the LIA

    “Global-warming antagonists, carrying the banner of natural climate variability, … add that the current warming isn’t being caused by anthropogenic CO2 but is instead simply a continuation of Earth’s recovery from the Little Ice Age.


    That is a bit misleading, Mann says. “Suggesting that Earth recovers from climate changes implies that the climate system works in a completely different way than we know it does based on physics,” he observes. “The climate doesn’t rebound. It isn’t like a spring that someone pulls and lets go. The primary changes are due to the response to forcings.


    This is a key statement. It reveals a mechanistic approach that works well in most areas of science, but that has failed badly in a few areas, such as (off the top of my head):

    Artificial Intelligence,
    Economics (none of the pooh-bah economists “called” the Great Recession),
    Value At Risk modeling (none of the models that Wall Street relied on to price its complex derivatives instruments actually modeled the real world, when push came to shove), and
    Psychology (at least in the form of mechanistic behaviorism),
    Sociology (which can only be trivially scientific),
    Politics (“scientific socialism”).

    The arrogant confidence that alarmist climatologists have in their models and predictions is reminiscent of the haughty assurance exuded by the AI researchers of the past. They too were riding high in their scientism and poured scorn on critics for decades. Finally they have admitted, mostly privately, that they were dealing with “a hard problem.” I think climatology has got a hard (nearly intractable) problem too. Certain fields are so chaotic, complex, and/or filled with “unknowns” that mechanistic, physics-type modeling isn’t appropriate, or is only a bit better than guesswork. It’s an attempt to put the ocean in a cup. We don’t know what devilish details may not have been taken into account, so the level of confidence we can get from such modeling must be low.

    “If natural variability was primarily ruling what we see today, we would still be in the Little Ice Age,” Mann continues. “We should have seen cooling in the past few decades because solar output has dropped off and there have been relatively more volcanic eruptions. To those who say today’s warming is natural variation, the natural forcings are actually pushing us in the wrong direction.”


    This omits mention of the PDO, which is the main forcing we contrarians have been harping about. Here is a quote mentioning it from a few pages later:

    Spencer estimates that the PDO effect can explain about 70%, or 0.5 °C, of the 0.74 °C global warming observed during the past century and that anthropogenic CO2 is responsible for the other 30%, or about 0.2 °C.
A new negative PDO phase might be getting started, Spencer says.

    5. Methane et al.

    Singer points to a recent study [whose implications] are that CH4 in combination with other minor forcings such as CO and volatile organic compounds add up to nearly equal CO2 as a forcing.… The Shindell study seemingly would lead to alterations in climate models, Singer points out, and in order to keep the models in agreement with past temperature observations, some other parameters would have to be arbitrarily adjusted. “That just doesn’t wash,” he says.


    Speak of the devil! This finding suggests that there are other devilish details that may not yet been found. It also implies that CO2 mitigation efforts would have only half the effect on temperature that alarmists have claimed. This much lower cost/benefit ratio calls the entire mitigation strategy into question.

    6. The Medieval Warm Period

    ”This is a key part of the battle in the climate debate,” Idso says. “If we can show that the temperature varies naturally with little influence from greenhouse gases, then the current warm period is nothing more than the recurrence of the natural climate-change cycle.”


    I agree – but I’d make that “THE key part of the battle” (rather than disputes over the thermometer record).

    7. Trends more important than temperatures

    In the end, absolute values of temperature are not what scientists are after anyway, but rather trends in warming or cooling over time.

    I agree. This is why, as Leif (and I) have said, the MWP is a much more important battleground than the current temperature record.

    8. The “Climate Canard”

    Since 1998, temperatures have leveled off, even as CO2 concentrations have continued to rise at a faster rate, leading to a “climate canard,” often referenced in climate-change discussions, that global warming has stopped. Global-warming antagonists say it’s yet another example of the CO2-temperature correlation falling apart.


    The words “since 1998” sets up a strawman for alarmists to knock down (see the next paragraph). Responsible “antagonists” claim that the leveling off has occurred since 2001 or 2002.

    But Mann points out that by cherry-picking data, recent temperatures could appear to be warming or cooling. Scanning the 10-year trend from 1998 to 2007, it looks like temperatures are cooling because 1998 was an uncharacteristically warm year. But taking the 10 years from 1999 to 2008, there is a warming trend, even though 2008 was the coolest year since 2000 because it included El Niño’s cooling phase, known as La Niña..

    But Mann’s 1999 starting date was also cherry-picked, because it was a cool year.

    In addition, every year from 2001 to 2008 is among the top 10 warmest years in the historical record.

    That’s a diversion from the more important point about the loss of correlation between CO2 & rising temperatures. Consider this: if temperatures continue to level off for the next ninety years, alarmists could similarly claim that all the years for a century have been in the top 100 years. But so what? The much more important point is that their correlation has gone bye-bye.

    9. Urban Heat Island Effect

    “You can eliminate urban stations from a data set or ignore land and look only at ocean data, and you still get a similar warming trend as you do with the corrected data,” Mann says.

    This isn’t the last word on this issue, although I’m not up on it well enough to offer a rebuttal.

    10. Misc.

    The article was smooth and professional, but it should have been twice as long to even scratch the surface. I hope several follow-up articles will be commissioned.

  271. Richard (18:30:07) :
    Could you do that experiment and let us know the results?

    If I was prepared to spend the money but I’m not really that interested, I just have an objection to such poorly designed experiments.

  272. Global Warming: Carbon Dioxide gas absorbs relatively little energy from sun light which heats the earth’s surface. Carbon Dioxide then absorbs a relatively great amount of heat from the earth’s thermal radiation. Carbon Dioxide thus contributes to the Greenhouse effect; it is a thermal blanket. However, the current levels of atmospheric Carbon Dioxide have NOT been proven to significantly influence temperatures nor climate. The current levels of atmospheric Carbon Dioxide have NOT been proven attributable to human activity. The current levels of atmospheric Carbon Dioxide may be due to increased temperatures where the temperatures are attributable to another source, ie. solar activity.

    The BBC “experiment” did NOT at all show the Greenhouse mechanism of any Greenhouse gas. The BBC and the scientist “Maggie” were completely duplicitous. It is not clear whether the “experiment” had any other purpose.

    1. The lamp heated the bottle wall.
    2. The gas absorbed the heat from the bottle wall by convection.

    Even if CO2 completely displaced the AIR in the one bottle, the number of molecules within each bottle remains equal at equal pressure. However, the two gases differ in their specific heat capacity. Assuming each gas absorbs heat by convection from the bottle walls similarly; one finds the temperature rise, deltaT, inversely proportion to the specific heat of each gas, Cp.

    IF Heat=moles*Cp*deltaT and each bottle contains the same number of gas molecules and each bottle absorbs the same heat and the heat transfers to the gas THEN Cpair/Cpco2=deltaTco2/deltaTair

    CO2 specific heat: Cpco2=37 J/mole K at 25C and constant pressure.
    AIR specific heat: Cpair=29 J/mole K at 25C and constant pressure.
    AND deltaTair/deltaTco2=1.25

    The air should get hotter! And indeed the bottle with AIR did get hotter than the bottle with CO2 in the video, for a time.

    Start Temperature CO2@25.0C and AIR@25.0C CO2 assumed room temperature.

    First Temperature check CO2@34.0C and AIR@35.6C !!!
    deltaTco2=9.0C and deltaTair=11.6C
    deltaTair/deltaTco2=1.28 Very nearly as predicted!!

    “Scientist” Maggie does not explain the result, she only giggles, and waits for the CO2 bottle to increase in temperature.

    Second Temperature check CO2@38.8C AIR@34.6C !!

    The CO2 Temperature is now higher than the AIR Temperature !! Vindication for “scientist” Maggie, NOT.

    Left unexplained, the AIR Temperature actually DECREASED from the first measurement!!!

    The “experiment” is ill designed and uncontrolled so it is difficult to determine the exact physical phenomena. The AIR may have started an internal convection cell with heat transporting from hotter bottle walls to cooler bottle walls or the unsealed, unpressurized bottles may have exchanged gas with the room. It is difficult to know without a better designed and valid experiments.

    The “experiment” allows one to draw several conclusions:
    1. The “experiment” has absolutely no relationship to Global Warming.
    2. The Public lacks critical thinking skills.
    3. The BBC also lacks critical thinking skills or promotes Anthropogenic Global Warming fraud.
    4. The Public is easily influenced by fraudulent scientists and fraudulent experiments.
    5. The BBC also is easily influenced by fraudulent scientists and fraudulent experiments or promotes Anthropogenic Global Warming fraud.
    6. “Top British Scientist” Maggie is a complete dolt, constructing a completely invalid experiment, incurious about the rise and then fall of the AIR Temperature, uttering completely unsupported conclusions.
    7. Since Real Climate is much more complex and “scientist” are imperfect maybe Global Warming is NOT settled science.

    “Not really, that’s why you do a control.”

    What are you talking about? My email was in regard to the experiment already over and done with. The results and any conclusions drawn from it were invalid. Even had they did some control runs and put controls in place beforehand off screen, the same conclusion applies – actually more so.

    The experiment was a poor one which was incapable of saying anything about the greenhouse effect as I’ve said above. However if it’s set up properly then what counts is the relative heating, the one with air acts as the control, that way if anything changes (say lamp power drops) the effect on each is the same. Of course it’s quite possible that something went wrong with the experiment (thermometer moved etc.) but that’s a different matter.

  276. kevoka (19:24:34) :
    Crosspatch at 12:23
    In my mind your explanation raises two questions:

    “At night 100% of the long wave IR is coming from the surface and THAT is where CO2 is going to have its impact … at night or during polar winter. CO2 is going to raise average temperature by increasing the minimum and that is why it has its greatest impact at the poles.

    1) During the polar winter, when the sun is not shining on the poles, doesn’t the long wave IR reduce accordingly in watts at the poles? I believe the Earths IR radiation varies directly with amount of sunlight (and thus would be a local effect). Or do we assume a global uniform IR radiation from the earth?

    No it depends on the 4th power of the temperature. At the poles downwelling IR exceeds solar most of the time, see:
    http://www.arctic.noaa.gov/np2008/gallery_np_weatherdata.html#weather

    “The poles are also where the air is driest and CO2 has the greatest relative impact on total impediment to radiation. Water vapor swamps CO2 less at the poles. CO2 would have almost no impact at the equator where water vapor by far swamps CO2 in both the amount of IR absorbed and the band of spectrum that it absorbs.”

    You are mistaken about the spectra of H2O and CO2.

    2) So here we know that Water Vapor is not uniformly distributed about the earths surface, in fact it stays relatively local. Is C02 uniformly distributed about the earths surface (i.e. it is everywhere 388 ppm or close to it)? And if so, then how would man made CO2 (which is generated in a highly localized fashion – more so than water vapor) get uniformly distributed?

    CO2 is uniformly distributed to within ~10ppm once you get away from the surface and the sources. How? Convection, diffusion etc. same as O2.

    I see no problem here.

    Haha, well said! This “experiment” does allow us to reach some valid conclusions after all… albeit none which were intended by the BBC or its “Top British Scientist”

    Was it just me or was anybody else waiting for Maggie to pull a coin out from behind the host’s ear?

  278. Professor King was providing his conclusions to an ongoing police investigation. If he has information, especially about mobile phone hacking and the source of the hacking, then shouldn’t he be making a statement to the police, and not making outlandish pronouncements about it on TV?

    As for the ‘experiment’, where was the ‘greenhouse’? The visible light was transmitted through the gas in the bottle, but what was reflecting infrared in the wavelength that is blocked by CO2? As demonstrated, the so called experiment is showing that direct sunlight on CO2 has an effect on the temperature, which is not at the ‘greenhouse wavelength’ of around 12 to 20 microns.

  279. you guys are thinking about this in a much to complex maner. yes C02 does act as a thermal blancket, when the sun goes down the I.R. radiation is thraped somewhat by the C02. But it nowere nere efficient enough to rais earths temperature even a degree.
    This is just an experamental theory i have because i am still young and learnig, but the greenhouse effect is somewhat caused by the atmosphere but that does not acount for all the warming. I believe that it may mainly be caused by the curveture of a planet, it’s size and proximity to the parent star. the curveture oft the planet and its atmosphere act somewhat like a lense. onother factor is that the backside of the atmosphere acts like a miror reflecting back what inferred radiation was captured. But i still do believe that my hypothesus about C02 being to dense to be a green house gas might be correct. but i am only 15 and still very eager to learn.

    The current warming we have seen was in my mind caysed by the P.D.O., and the resent entense solar cycles. Now that the P.D.O. has gone negative, and the A.O. in addition with low solar irradiance we will see a steady coling trend over the next 30 to 50 years. how much of a cooling trend i dont know, but i hope it makes all the sheeple wake up and go “wait its getting colder right?” this winter in the northern hemisphere is the first of many like it and mor intense than it. I live in houston tx and we have had snow 3 years in a row now, that to me is a sign of theings to come.
    so all you global warming domesayers whatch out, beacouse what goes arround comes arround.

  280. In my comment (01:46:30) I wrote that 1600 ppbv (1.6 ppmv) is the same as 0.000016%. Sorry, too many zeros … should have been 0.00016%. That tiny amount relates to total methane in the air we breathe. Yet the warmers go bananas over it, insisting that cows and the like should belch less and that we should eat vegetables instead of meat.
    Re cows’ carbon footprint, CO2 makes grass, cows eat grass, cows die and CO2 returns to air, CO2 makes grass. Virtually zero carbon footprint. Conclusion: the warmers don’t know what they’re talking about.

  281. Use some other heavy gas instead of CO2, i.e. Argon, which is clearly no GHG, you get the same result with this foolish BBC experiment.

    This BBC experiment neglects lots of other physical laws, i.e. radiation transport, only to take the most important example.

    All heavy gases (with big molecules), act the same way.

  282. The main problem with that kitchen top experiment by the BBC is that it demonstrates how much LESS of the sun’s heat will be able to penetrate the atmosphere and reach the earth’s surface with extra CO2 in the atmosphere.

    The experiment, as they have set it up, is proving global cooling not warming.

  283. I found a very good, condensed & relatively easy to read and understand explaination of the “greenhouse effect” by Lindzen and Emanuel here:

    http://www-eaps.mit.edu/faculty/lindzen/198_greenhouse.pdf

    This shows (according to the theory) why upper tropospheric temps should increase more than the surface (at least in the tropics), and also why CO2 levels near the ground don’t matter much — levels around the tropopause are what count, where radiation controls the temps. Convection controls temps nearer to the ground.

  284. Roger Knights (10:57:08) :
    Comments on the Chemical & Engineering News article, “Global Warming and Climate Change,” of Dec. 21, 2009
    […]

    “Global-warming antagonists, carrying the banner of natural climate variability, … add that the current warming isn’t being caused by anthropogenic CO2 but is instead simply a continuation of Earth’s recovery from the Little Ice Age.


    That is a bit misleading, Mann says. “Suggesting that Earth recovers from climate changes implies that the climate system works in a completely different way than we know it does based on physics,” he observes. “The climate doesn’t rebound. It isn’t like a spring that someone pulls and lets go. The primary changes are due to the response to forcings.


    This is a key statement. It reveals a mechanistic approach that works well in most areas of science, but that has failed badly in a few areas, such as (off the top of my head):

    Artificial Intelligence,
    Economics (none of the pooh-bah economists “called” the Great Recession),
    Value At Risk modeling (none of the models that Wall Street relied on to price its complex derivatives instruments actually modeled the real world, when push came to shove), and
    Psychology (at least in the form of mechanistic behaviorism),
    Sociology (which can only be trivially scientific),
    Politics (“scientific socialism”).

    The arrogant confidence that alarmist climatologists have in their models and predictions is reminiscent of the haughty assurance exuded by the AI researchers of the past. They too were riding high in their scientism and poured scorn on critics for decades. Finally they have admitted, mostly privately, that they were dealing with “a hard problem.” I think climatology has got a hard (nearly intractable) problem too. Certain fields are so chaotic, complex, and/or filled with “unknowns” that mechanistic, physics-type modeling isn’t appropriate, or is only a bit better than guesswork. It’s an attempt to put the ocean in a cup. We don’t know what devilish details may not have been taken into account, so the level of confidence we can get from such modeling must be low.

    As Ken Wilber put it, “science can’t predict where my dog will be in the next 15 minutes”.

    Just to be clear, science is great fantastic stuff. I love science. I love technology. Unfortunately many greenies kinda hate science, they deny progress.

    There are some huge confusions going on, where those who love science will happily point out its shortcomings, whilst those who don’t like science will hold it up as “absolute” (but only when it suits them).

    If I may just take a quick tour round the houses a moment…

    A greenie acquaintance of mine visibly winces when you mention the word “progress”. He interjects, “is a nuclear bomb better than a mortar?”

    My acquaintance doesn’t distinguish between “bomb” as technology and “wanting to kill” as morality. (There is a vast difference between science-as-truth and morality-as-goodness. )

    And because he thinks nukes are “bad”, he thinks modern man is “worse” than early man. He forgets that early man’s only loyalties were to his tribe—anybody else was fair game. Today if I attack a stranger I am thrown in jail. In earlier tribal epochs, attacking strangers (ie. not of my tribe) was the day’s highlight.

    Just think of the numbers… thousands of tribes attacking each other over tens of thousands of years… just like, you know those lovely furry apes, they look so noble and natural, the same ones that go around killing the babies of other apes?

    So I tell my acquaintance, yep, nukes are better because they were produced by more civilised minds that have greater compassion. — That really winds him up.

    There is a similar confusion around science and technology and population and sustainability. Greenies quote “the science” because they think that’s what people believe, not because that’s what greenies themselves believe.

    Greenies come from post-modern culture where the perception is that you almost don’t think there is any such thing as truth, because all truths are simply “narratives” constructed by power structures in society.

    So greenies say, OK, let’s construct our own narrative and build own own power structures, using NGOs and charities, to push our narrative into the culture. They use “the science” as their narrative, but if everyone believed in aliens, they’d be pushing the narrative through “the aliens say…”

    This is very obvious in the issue of genetic modification. Why is it that greenies completely reject any science that says there is no evidence that genetic modification is bad, and yet these same greenies will call you a “flat earther” if you question global warming science??

    But in amongst all this confusion, unfortunately the scientism of some groups — the naive belief that everything is only properly studied using reductive scientific methods — is churning out a bunch of stuff that, surprise surprise, is failing to make any useful predictions about climate. But is is convenient garbage, is is “fertilizer” for greenies, to grow and nurture their preferred narrative, that humans are “bad”, that we must “reduce our numbers”, and so on.

    But of course, if you are inside these science fields where mechanistic methods just don’t get you very far towards anything practical and useful, you nevertheless have to remain faithful and humble to the field and to your peers, and be seen to be spending years citing other people’s papers before you’re deemed worthy of having anything useful to say, even if what you do end up saying is just more scientisms about how you can predict the climate to within a degree in a hundred years…

    Scientisims predict climate, and greenies ignore science but use scientisims to foster a narrative onto the people. It’s a wild party!

  285. nathan

    density C02 reflects more light than it lets through, there fore cooling the planet not warming it making it an “ice house gas” not a green house gas. plus C02 is plant food so that disproves them calling it a pollutant. There i have thus dis proven the entire global warming theory, and i am only 15.

    Being young it’s easy to be too ambitious. Science is about methodically studying each aspect of the subject of your interest. As you learn so you will look back and wonder how what seemed like common sense to you at one time does not apply to the real world.

    Thee nature light has confounded man from the outset of scientific exploration. Needless to say your obsevation is wrong in so many ways in that I won’t try here to explain.

    You seem to be interested in this subject as I was at your age. There is no easy road. You must study more if you want to be taken on a journey into a world that will challenge every aspect of what you would think of as common sense,

    It doesn’t mean that you can’t form your own hypotheses as you go but be prepared to dump them when they contadict what you have learned.

  286. Hi Stefan. Good observations on greenie psychology, as usual.

    PS to my comments above: The effect of soot on Arctic warming and melting is another recently discovered devilish detail that (again) indicates that the good fit of climate models prior to its discovery undermines their credibility. It means that they were either tweaked improperly, or were so fundamentally bad, that they are untrustworthy. I.e., the more post hoc rejiggerings are needed, the worse these models look in comparison to Punxsutawney Phil, a wooly caterpillar, or Ye Olde Farmers’ Almanac.

    I suspect there are other recently discovered devilish details that could be added to the indictment. Any nominations?

  287. They have a new lesson up now with the offending heresy scrubbed from the lesson. http://www.srh.noaa.gov/jetstream//atmos/ll_gas.htm

    I’ve sent emails asking why they changed it to the following persons.

  288. I have at last received my proforma rebuff from the BBC. How disappointing that a great institution has reached such a low point.

  289. There’s a MASSIVE flaw in the BBC experiment. While the infrared light energy may be absorbed by increased levels of CO2, this is NOT a good example of the process on Earth.

    When the infrared energy passes through the air, the majority of the energy does NOT go outward into space, it hits the Earth and is absorbed by rocks, trees, dirt, and other things on the ground. So, either the air is warmed OR things on Earth are warmed; either way the air will be warmed by the same energy.

    It would be interesting to do the exact same experiment with a sheet of black paper inside BOTH jars and measure the temperature. Whether the energy is absorbed by the CO2 OR by the black paper, the total energy is still the same. Thus, the temperatures should be the same.

    Pity, I wasn’t there during the filming of this segment, my comments would have pissed of the scientist trying to pull a fast one on the people.

  290. When I was having a discussion with a warmist the other day I pointed out that news item after news items shows either New Orleans Katrina or Tsunami or any other natural disaster footage with a climate change alarmist voicetrack. He said that was just poor journalism which unfortunately seems to be the only type around. To the BBC’s credit they did show it snowing outside. And no one at the BBC can do much more than this and expect to keep their job or ever get a promotion.

  291. This was a sham. I am shocked that the once-revered BBC could indulge in such ‘smoke and mirrors’. If it wasn’t, as admitted, a “scientific experiment”, then why bother to do it? The answer is of course is it was to make a political point, one that cannot easily be demonstrated scientifically. I am genuinely saddened to the core that my BBC – something I once adored (when I was younger, and those running it are not those who do now), is indulging in such chicanery. I repeat once again; if it’s admittedly not scientific, why do it? What was your agenda. Even Pravada is laughing at you now; how the mighty fall.

  292. Just a note of clarification: Prof Kilty teaches at Laramie County Community College (LCCC), not at the University of Wyoming. The two schools are closely related, but not the same.

  293. I have not read the entire thread but has Prof. King informed the police that private telephone conversations have been intercepted and made public. I believe this is breaking the law and should be investigated.

    As the Chief Scientist it is his duty to do so.
