Congenital Climate Abnormalities

Guest Post by Willis Eschenbach

[see Updates at the end of this post]

Science is what we use to explain anomalies, to elucidate mysteries, to shed light on unexplained occurrences. For example, once we understand how the earth rotates, there is no great need for a scientific explanation of the sun rising in the morning. If one day the sun were to rise in the afternoon, however, that is an anomaly which would definitely require a scientific explanation. But there is no need to explain the normal everyday occurrences. We don’t need a new understanding if there is nothing new to understand.

Hundreds of thousands of hours of work, and billions of dollars, have been expended trying to explain the recent variations in the climate, particularly the global temperature. But in the rush to find an explanation, a very important question has been left unasked:

Just exactly what unusual, unexpected temperature anomaly are we trying to explain?

The claim is made over and over that humans are having an effect on the climate. But where is the evidence that there is anything that even needs explanation? Where is the abnormal phenomenon? What is it that we are trying to make sense of, what is the unusual occurrence that requires a novel scientific explanation?

There are not a lot of long-term temperature records that can help us in this regard. The longest one is the Central England Temperature record (CET). Although there are problems with the CET (see Sources below), including recent changes in the stations used to calculate it that have slightly inflated the modern temperatures, it is a good starting point for an investigation of whether there is anything happening that is abnormal. Here is that record:

Figure 1. The Central England Temperature Record. Blue line is the monthly temperature in Celsius. Red line is the average temperature. Jagged black line is the 25-year trailing trend, in degrees per century.

Now, where in that record is there anything which is even slightly abnormal? Where is the anomaly that the entire huge edifice of the AGW hypothesis is designed to elucidate? The longest sustained rise is from about 1680 to 1740. That time period also has the steepest rise. The modern period, on the other hand, is barely above the long-term trend despite urban warming. There is nothing unusual about the modern period in any way.

OK, so there’s nothing to explain in the CET. How about another long record?

One of the world’s best single station long-term records is that of the Armagh Observatory in Ireland. It has been maintained with only a couple minor location changes for over 200 years. Figure 2 shows the Armagh record.

Figure 2. Temperature record for Armagh University. Various colored lines as in Figure 1.

We find the same thing in this record as in the CET. The fastest rise was a long, long time ago. The modern rise is once again insignificant. Where in all of this is anything that requires billions of dollars to explain?

Finally, what about the global record? Here, you don’t have to take my word for it. A much chastened Phil Jones (the disgraced former Director of the CRU of email fame), in an interview with the BBC on Friday, February 12, 2010, answered a BBC question as follows:

Do you agree that according to the global temperature record used by the IPCC, the rates of global warming from 1860-1880, 1910-1940 and 1975-1998 were identical?

An initial point to make is that in the responses to these questions I’ve assumed that when you talk about the global temperature record, you mean the record that combines the estimates from land regions with those from the marine regions of the world. CRU produces the land component, with the Met Office Hadley Centre producing the marine component.

Temperature data for the period 1860-1880 are more uncertain, because of sparser coverage, than for later periods in the 20th Century. The 1860-1880 period is also only 21 years in length. As for the two periods 1910-40 and 1975-1998 the warming rates are not statistically significantly different (see numbers below).

I have also included the trend over the period 1975 to 2009, which has a very similar trend to the period 1975-1998.

So, in answer to the question, the warming rates for all 4 periods are similar and not statistically significantly different from each other.

So in fact, according to Phil Jones (who strongly believes in the AGW hypothesis) there is nothing unusual about the recent warming either. It is not statistically different from two earlier modern periods of warming. Since these warming periods were before the modern rise in CO2, greenhouse gases cannot have been responsible for those rises.

So my question remains unanswered … where is the anomaly? Where is the unusual occurrence that we are spending billions of dollars trying to explain?

The answer is, there is no unusual warming. There is no anomaly. There is nothing strange or out of the ordinary about the recent warming. It is in no way distinguishable from earlier periods of warming, periods that we know were not due to rising CO2. There is nothing in the record that is in any way different from the centuries-long natural fluctuations in the global climate.

In other words, we have spent billions of dollars and wasted years of work chasing a chimera, a will-of-the-wisp. This is why none of the CO2 explanations have held water … simply because there is nothing unusual to explain.

JONES BBC INTERVIEW:http://news.bbc.co.uk/2/hi/science/nature/8511670.stm

Jones also makes the interesting argument in the interview that the reason he believes that recent warming is anthropogenic (human-caused) is because climate models can’t replicate it … in other words, he has absolutely no evidence at all, he just has the undeniable fact that our current crop of climate models can’t model the climate. Seems to me like that’s a problem with the models rather than a problem with the climate, but hey, what do I know, I was born yesterday …

[UPDATE 1] Further evidence that nothing abnormal is happening is given by the individual US state record high temperatures. Here are the number of US state record high temperatures per decade, from the US National Climate Data Center (NCDC):

Figure 3. US state high temperature records, by decade. In the period 1930-1940, twenty of the fifty US states had their highest recorded temperature.

As you can see, the recent decades have not had record-beating high temperatures, nor are they unusual or abnormal in any way. Nearly half of the high temperature records were set back in the 1930-1940 decade.

[UPDATE 2] Here is another look at the lack of any abnormalities in climate data. I will add more as they come up. This is data on snow extext, from the Rutgers University Global Snow Lab:

Figure 4. Snow cover variation, Northern Hemisphere. Transparent blue line shows the month-by-month cover, and the red line is the average snow cover.

So, nothing to see here. There is no evidence that the climate has gone off course. There is no evidence of the claimed reduction in snow cover which is supposed to provide a positive feedback to warming. In fact, the surprising thing is how little the snow cover has changed over the last forty years.

[UPDATE 3] We often hear about the vanishing polar sea ice. Usually, however, people only look at half of the picture, Arctic sea ice. Although you wouldn’t know it from the scare stories, we do have a South Pole. Here is the record of global sea ice, 1979-2006

Figure 5. Global ice area variation. Blue line shows the month-by-month area, and the red line is the average area. DATA SOURCE

This illustrates the non-intuitive nature of climate. As the global temperature was climbing from 1985 until 1998, global sea ice was increasing. Since then it has decreased, and currently is where we were at the start of the satellite record. Variation in the average is ±2%. Nothing unusual here.

[UPDATE 4] Another oft-mentioned item is tropical cyclones. Here is the record of Accumulated Cyclone Energy, for both the Globe and and Northern Hemisphere, from Ryan Maue .

Figure 6. Accumulated Cyclone Energy. Upper line is global, lower line is Northern Hemisphere. Area between lines is Southern Hemisphere

As you can see, there is nothing out of the ordinary in the accumulated cyclone energy either. It goes up … it comes down. Nature is like that.

[UPDATE 5] Arctic temperatures are often cited as being anomalous. Here’s the record for Alaska;

Figure 7. Alaska Temperature Average from First Order Observing Stations. DATA SOURCE .

The Alaskan temperature is regulated by the Pacific Decadal Oscillation (PDO). The PDO shifted from the cool phase to the warm phase around 1976 [typo corrected, was incorrectly listed as 1986], and has recently switched back to the cool phase. As you can see, other than the step changes due to the PDO, there is little variation in the Alaska temperatures.

[UPDATE 6] There has been much discussion of the effect of rising temperatures on rainfall. Here is the CRU TS3 global precipitation record:

Figure 8. Global Precipitation, from CRU TS3 1° grid. DATA SOURCE

As in all of the records above, there is nothing at all anomalous in the recent rainfall record. The average varies by about ± 2%. There is no trend in the data.

[UPDATE 7] People keep claiming that hurricanes (called “cyclones” in the Southern Hemisphere) have been rising. They claim that damage from hurricanes in the US have been going up. Here is data on hurricane damage:

The figure above shows normalized US hurricane losses for 1900 to 2009. It shows an estimate of what hurricane damages would be if each hurricane season took place in 2009. The dark line shows the linear best fit from Excel. Obviously, there is no trend. This makes sense as there has also been no trend in U.S. landfall frequencies or intensities over this period (in fact, depending on start date there is evidence for a slight but statistically significant decline, source in PDF).
In addition, a new WMO study in Nature (subscription required) says (emphasis mine):
In terms of global tropical cyclone frequency, it was concluded that there was no significant change in global tropical storm or hurricane numbers from 1970 to 2004, nor any significant change in hurricane numbers for any individual basin over that period, except for the Atlantic (discussed above). Landfall in various regions of East Asia26 during the past 60 years, and those in the Philippines during the past century, also do not show significant trends.

[UPDATE 8] You’d think, from all of the shouting about the greenhouse radiation, that we would have seen some change in it over the last few decades. Here is NOAA data on average outgoing (from the earth to space) longwave (greenhouse) radiation (OLR).

Figure 10. Global Outgoing Longwave Radiation. NOAA Interpolated OLR

Change in the average OLR over the period of record is less than ± 1%, and change since 1980 is only ± 0.5%. The current average value is the same as in 1976.

[UPDATE 9] OK, how about droughts? After all, droughts are supposed to be one of the terrible things that accompany warming, and the earth has warmed over the last century. Here’s the Palmer Drought Severity Index for that time span, 1901-2002:

Figure 11. Palmer Dourght Severity Index. CRU self-calibrating PDSI

Once again, despite going up some and down some, we’ve ended up just where we started.

[UPDATE 10] More on the Arctic. From Polyakov et al ., we have this:

Figure 12. Arctic Temperature Anomaly . DATA SOURCE

The study used temperature stations from all around the shore of the Arctic Ocean, plus buoys and ice stations. It covered the area north of the Arctic Circle, that is to say the entire Arctic.

This matches an analysis I did last year of the Nordic countries. Here is a result from that study.

Figure 13. Nordic Land Temperature Anomaly. Original caption says “I used the NORDKLIM dataset available here . I removed the one marine record from “Ship M”. To avoid infilling where there are missing records, I took the “first difference” of all available records for each year and averaged them. Then I used a running sum to calculate the average anomaly. I did not remove cities or adjust for the Urban Heat Island (UHI) effect.”

Note that, as we would expect, the temperature of the Nordic Countries is similar to that of the Arctic as a whole.  This adds confidence to the results. I show the trends for the same intervals as in Fig. 12.

Again, there is nothing out of the ordinary here. The recent Arctic warming is often held up as evidence for human influence on the climate. The data shows the Arctic warming from 1902-1938 was longer and stronger than the recent warming. There is nothing for CO2 to explain.

[UPDATE 11] More on storms. We’ve looked at cyclones, but what about storms in the temperate zones? Here are the results from a study (pay per view) by Bärring and Fortuniak called Multi-indices analysis of southern Scandinavian storminess 1780-2005 and links to interdecadal variations in the NW Europe-North Sea region. Here’s one of their graphs:

Figure 14. Changes in storms in Lund and Stockholm, Sweden. Increasing values shows increasing storms.

About this graph, the authors say:

(1) There is no significant overall long-term trend common to all indices in cyclone activity in the North Atlantic and European region since the Dalton minimum.

(2) The marked positive trend beginning around 1960 ended in the mid-1990s and has since then reversed. This positive trend was more an effect of a 20th century minimum in cyclone activity around 1960, rather than extraordinary high values in 1990s. Both the 1960s minimum and the 1990s maximum were within the long-term variability.

(3) Because the period between the 1960s minima and the 1990s maxima spans a substantial part of the period covered by most reanalysis datasets, any analysis relying solely on such data is likely to find trends in cyclone activity and related measures.

Can’t be much clearer than that. There’s no change in North Atlantic storminess.

[UPDATE 12] More on rainfall, this time extreme rainfall and floods. I took the data from Trend detection in river flow series: 1. Annual maximum flow, and used it to compare record river flows by decade. Here are those results:

Figure 15. Maximum River Flow Index for US, European, and Australian rivers.

The math on this one was more complex than the record state temperatures. The river records are of different lengths, and they don’t span the same time periods. Of course, this affects the odds of getting a record in a given year.

For example, if a river record is say only ten years long, the random chance of any year being the maximum is one in ten. For the longest record in the dataset above, it is one in 176. In addition, the number of river records available in any year varies. To adjust for these differences, I took the odds of the record not being set in that particular year for each stream. This is (1 – 1/record length). I multiplied together all of those (1-1/len) odds for all the records available in that year to give me an overall odds of that year not being a record.

Finally, I took the average of those overall odds for the decade, and multiplied it by the actual count of records in that year. This gave me the maximum river flow index shown above. If there were lots of short records in a given decade, we’d be more likely to get a record by chance, so the record count in that decade is accordingly reduced. On the other hand, if there were only a few long records in that decade, there’s not much chance of a record being set randomly in that decade, so the count would be reduced less.

As you can see, there is no sign of a recent increase in the adjusted number of records. Or as the authors of the study say:

The analysis of annual maximum flows does not support the hypothesis of ubiquitous growth of high flows. Although 27 cases of strong, statistically significant increase were identified by the Mann-Kendall test, there are 31 decreases as well, and most (137) time series do not show any significant changes (at the 10% level).

Once again, we see no sign of the changes in climate predicted by the UN IPCC. What were the changes they predicted?

Figure 16. Observed and Projected Changes from the UN IPCC Third Assessment Report.

As you can see above, there is no increase in extreme drought, precipitation, extreme high temperatures, or cyclone events.

[UPDATE 13] Oh, yeah, a pet peeve of mine. You know how they always say “Yeah, but nine out of the last ten years have been among the ten warmest years of the record”, as though that proved that the last ten years was an unusual, anomalous time?

The trouble with this argument is that in a time of rising temperatures, that is often true. The temperature is rising, so where would you expect the warmest years to be?

How often is it true? Thanks for asking, here’s the data from the GISS temperature record .

Figure 16. Number of “Top Ten” years in the GISS global temperature record up to that point that occurred in the ten years previous to a given year.

So yes, nine of the last ten years were in the top ten years in the record … but that was true three times in the 1940’s. So once again, there is nothing unusual about the recent warming.

[Edited to Add] I got to thinking about the IPCC WG1 report, which is the science report. People always claim that it contains nothing but science, and none of it has been overthrown. So I pulled up the Summary for Policymakers. Under the second section, called “Direct Observations of Climate Change”, the very first item says (emphasis mine):

Eleven of the last twelve years (1995–2006) rank among the 12 warmest years in the instrumental record of global surface temperature9 (since 1850). The updated 100-year linear trend (1906 to 2005) of 0.74°C [0.56°C to 0.92°C] is therefore larger than the corresponding trend for 1901 to 2000 given in the TAR of 0.6°C [0.4°C to 0.8°C].

Since the claim was slightly different than the one I analyzed above, I went back and looked at the top twelve. Here they are:

Figure 17. Number of “Top Twelve” years in the GISS global temperature record up to that point that occurred in the twelve years previous to a given year.

Once again, nothing unusual … yes, the earth has been warming, but not in any unusual or anomalous way.

Next, there is no “therefore” in the comparison of the trends. The mere fact that a number of the warmest years were in the last 12 does not guarantee an increase in the trend. If the post 2000 trend continued to increase regularly and very slightly, there would always be 12 of the warmest years in the last 12 … but the 100 year trend would steadily decrease.

[UPDATE 14] The predicted acceleration of sea level rise is one of the favorites of those who want to scare people about CO2. Since 1992, sea level has been measured by satellite. Here is the record of sea level rise over that period:

Figure 18. TOPEX satellite sea level data. The satellite measures the sea level rise using radar. DATA SOURCE

As you can see, rather than accelerating, sea level rise has been slowing down for the past few years. Another inconvenient truth …

[UPDATE 15] Extreme weather events are a perennial favorite among the forecast ills from purported climate change. I found good data on the maximum three day rainfall totals for eight areas on the US Pacific Coast. The areas are Western Washington, Northwest Oregon, Southwest Oregon, Northwest California, North Central California, West Central California, Southwest California, and Southern California. For each record, I ranked the results, and averaged them across the 8 records. This gave me a ranking index showing which years had the most extreme events over the entire region. Fig. 19 shows the results, with larger numbers showing higher ranked years (those with more extreme rainfall events).

Figure 19. Extreme rainfall events, averaged over eight US Pacific Coast climate zones DATA SOURCE

As you can see, there is nothing unusual in the data. The number of extreme events hasn’t changed much over the period, and there is no long-term trend.

Thanks Willis.
I did what you did last year, with the same result.
It has been very difficult to get that information out.
I’m very glad you did.

Nice way to put it.
Of course, there are peer reviewed papers to the contrary, that the current warming isanomalous, and needs explaining. But the statistics (used in them) are questionable, and there are other papers to the contrary. Which brings us back to where you are.

February 13, 2010 4:09 am

Willis. William of Occam would no doubt agree with you. It’s the simplest of all explanations, that there is nothing there to explain, at least as regards CO2.
That will be shocking to many. But what a treat it is to see the whole thing unravel, albeit in slow motion.

Al Gore's Holy Hologram
February 13, 2010 4:21 am

In ancient times the Sumerians and Babylonians came up with the flood myth to scare the population from ‘making too much noise which angered the gods’. It was the theocratic way to deal with population growth. But it didn’t work, population size kept growing and innovation helped deal with increased demand for food, housing and fuel.
The ancient Hindus, Turks and Egyptians deified cows to prevent their slaughter as the milk was very important to a population who could not afford a meat diet and to a farming culture who did not know how to deal with increased demand for meat. Here theocracy instead of reason helped out again.
And that’s the way politicians work. Instead of giving us honest rational conversation, even in a so-called age of reason and enlightenment, they churn out the same kind of lies that theocracies did for centuries. Instead of saying we need to build a modern infrastructure and renewable energy to deal with the energy security problem, they fed us Biblical styled horror stories about the world drowning or burning if consumers don’t atone for their sins and abandon certain freedoms. Gaia will turn her anger upon us if we do not heed the wisdom of her modern Noah-styled prophet (Al Gore).
We’re having these heated debates, mud-slinging, name calling, fights, fanatics trying to use science to advance their political ambitions, etc. And all because the energy security issue has been transformed via AGW theory into a moral and spiritual issue because the powers that be decided to frame it as a religious issue, which brings out a lot of heated emotions and conflicts which achieve nothing for the majority and allow a minority to profit.
Get rid of this AGW nonsense. Admit that its time is up. Reframe it as an energy security issue that the whole world should take part in. Introduce global personal carbon trading between very rich individuals and very poor individuals with everyone else in between free from the trade, so that the poor may decide as individuals to live low carbon lives while earning an income from the rich who benefit. We can scrap most of the welfare system this way, streamline it and make it more efficient.

Brilliant! Willis, you have an incredible talent for explaining complex, or in this case, really straightforward, (except for those whose eyes and ears are sealed shut), issues, in clear plain terms. This little essay should be on the front page of all of the dailies. You make it obvious that we have a case of “if it aint broke, why fix it!”

February 13, 2010 4:27 am

Are we to conclude from this that even anthropogenic global urban heat island climate change has not been scientifically proven? I’ll bet that Santa Claus, the Tooth Fairy and even the Great Pumpkin aren’t real either. My beliefs lie shattered at my feet!

The article would be fine if the fundamental question AGW proponents were asking was the cause of recent warming. Actually that is not what most of the AGW people are arguing. Their question is not “what has caused the recent warming” but “will pumping billions of tons of CO2 into the atmosphere cause future warming”.
That is a legitimate line of study – as yet with an inconclusive set of answers. I think the IPCC made a big mistake, and spoiled their argument badly, by trying to link the most recent period of warming to AGW.

Neville
February 13, 2010 4:29 am

The other reason we shouldn’t be wasting those billions $ is much more obvious, it won’t make a scrap of difference.
The International energy Agency ( IEA ) has warned OECD countries that even if they reduced their GHG’s to zero by 2030 they will not stabilize co2 levels in the atmosphere at 450ppm.
Why, because by 2030 non OECD countries will be producing more than 25 billion tonnes of ghg’s while OECD countries will be producing less than 15 billion tonnes.
Martin Ferguson Minister for resources and energy ( Australia) states that in the next 10 years China alone will bring online about 1000 average sized coal fired power stations, equivalent to 34 times Australia’s coal burning generation capacity. ( July 2009)
So even if you believe the AGW nonsense it’s still a complete waste of time and money, Lomborg got it right we should be spending our resources on adaptation, whether we are battling natural climate change or whatever.

February 13, 2010 4:30 am

Thanks for this. Nothing has really changed. True. When I see trends of only 0.25 to 0.5 degree per century I always get suspicious. I mean how accurate was our equipment 100 years ago? If there is some warming due to humans it is probably due to AHF and not AGW. I mean for example, how much cooling water is used (to produce water vapor) for nuclear energy? Water vapor is a stronger greenhouse gas than carbon dioxide.
I have proven for myself that the increase noted in carbon dioxide is nothing to be afraid of, it is just a scam. There is a whole industry now based on this lie and even our pension money is invested here. If you want to probe the issue, just ask the so-called experts this question::
I will agree that CO2 traps heat (from earthshine 24hours per day) because of the absorption of CO2 in the 14-15um wavelength. I say, good, fine I believe you. But likewise there must be cooling because of various absorptions of CO2 in the range from 0-5 um (from sunshine 12 hours per day)! This cooling must logically take place everywhere where there is CO2 and where sunlight hits on the molecule regardless of height or pressure.. It is even so apparent that this happens that this radiation can be measured as it reflects back from the moon. So my question is: exactly how much cooling and how much warming is caused by the carbon dioxide?
So far no one has been able to show me the balance sheet i.e. exactly how much cooling and how much heating is caused by CO2.
What I have found is that I cannot find this research because it seems to me that such an simple observation of mine (ie. that CO2 also must cause cooling) has never been taken into account. Where the IPCC got its values from (for “forcings”) is a mystery to me but it is appears not to be based on actual measurements (research) that would produce a formula of some sorts. I think they were all just weighted values.

Willis-
I have used the same line of reasoning to hit otherwise sensible skeptical, pro-science people over the head with, to no avail.
Take, for instance, raw-US surface temperature data, and juxtapose it with UAH satellite data, and there is about the same rate of temperature rise: about 1C degree per century.
In the US, “Bill Nye the science guy” was heard to proclaim on MSNBC that of course recent epic snow storms blanketing the 120 millions in the Northeast are because of global warming! Why? Because added energy (from ACO2) HAS to go somewhere~
NEVERMIND that humidity levels over decades are actually declining, and that new record high temperatures in the US (by state) are absent.
Once in the grip of a theory, normally sensible and scientific people are incredibly averse to assessing a widely-accepted belief. One is reminded of the famous Stanley Milgram experiments of the 1960s.
In these, it was shown that people would inflict killing levels of pain on an innocent “test subject” merely on a scientists say so – shades of the Final Solution!
My only solution is the stern infliction of repeated doses to Popperian skepticism! Take the mindless and brainwashed and put reality testing into them.

Excellent post Willis. The only addition I would make is the infamous graph that Dr. Pachauri used. I would contrast the limted data long term of your graphs with the more universal data but short termed of his graph. The comparison would be the antimethodological approach of Dr. Pachuri using trends of decreasing length until using lengths less than 30 years conflicting with the very institution that he heads. Such grandstanding deserves more contempt that the climategate scientists. One can correct the science with publishing the correction. How does one address such antimethodological approachs by the very person in charge of making sure the methodology is correct?

Very well put, and I for one, understand. So do many others.
Why, then, have supposedly intelligent politicians the world over seized upon the (according to them, indisputable) proposition that the world is warming, and that it’s our fault?
How come they are so gullible? Well, I think we all know the answer to that one – they’;re not, but they DO recognise an opportunity to exert greater control on the populace, frighten them half to death, and relieve them of their cash at the same time.
The most surprising thing is that, having been caught with their hands in the till, they continue to bluster their innocence, and continue with their preposterous dogma.
How do we shake this ideology? How many are involved, and how deep does it go? We know that the UK Labour party are fully on board, and refer to sceptics as “flat-earthers”, “deniers” or even “liars”. We also know that the mainstream press have a fear of fronting for sceptic science, as do the BBC who are merely the Pravda of the British government. It obviously goes far deeper than most of us are aware, and names of organisations such as “Bilderberg”, “Frankfurt School”, “Club of Rome” and the “Fabian Society” seem to appear regularly.
If this is some deep-seated, worldwide plan to change our lives, what can we possibly do to oppose it? Who can we trust? We can see that Investigation Groups, Think-Tanks, and similar organisations consist of members who have their own agendas borne of the common cause – how can we EVER achieve an independent enquiry into this sinister movement, when almost everyone seems to be part of it? It’s like a bad dream – we can’t rust anybody. They have true sceptic scientists by the short and curlies, in that they dare not raise their heads above the parapet for fear of losing credence, funding, posts or all three. It’s an insidious cancer. Is there a cure?

We cannot know the answer to the anthropogenic effect without precise knowledge of our climate’s sensitivity to carbon dioxide. And this, of course, is a difficult bit of knowledge to acquire. We cannot make sensible and safe policy prescriptions without it, however, and all efforts should be bent toward its acquisition. Everything else is just blowing in the wind.

THERE IS NO ANOMALY. IPCC AR4, Ch 3 quotes a warming over the last century of 0.6 C and a standard deviation of 0.25 C. The 0.6 C warming is within +/- 3 standard deviations, or +/- 0.75 C. The warming is not significant; it falls within natural variation. THERE IS NO ANOMALY by IPCC’s own numbers.

February 13, 2010 4:53 am

So here’s the test…
Can the models (which require CO2 increase to match current trend) replicate any of the earlier warming periods without invoking a CO2 increase? Perhaps one of the modellers out there can demonstrate this for us and then release the code and data for scrutiny?

Thank you for this explanation, Mr. Eschenbach. It is simple and elegant. Not to mention convincing. Quoting a major proponent of climate change and global warming to make the point is very helpful. I doubt it will satisfy the majority of believers, but it will help me explain my point of view, and I appreciate it.

February 13, 2010 5:08 am

@ TLM (04:28:52) :
“Their question is not “what has caused the recent warming” but “will pumping billions of tons of CO2 into the atmosphere cause future warming”.”
The historical record shows no major increases in temperature with increasing output of CO2 into the atmosphere, which suggests that the influence of CO2 is considerably less significant than has been made out. It is therefore fair to say that in the near future it is unlikely to be a significant factor.
I hope that with recent events and the rise of questioning voices in the scientific community that we will soon see other more sensible theories advanced for the operation of the mechanisms of climate change on this planet which have a greater foundation in reality.

I strongly object. Political price-fixing is price-fixing, market distortion is market distortion, no matter how you put it. Using tax payer money to subsidize needed developments – like developing better solar power, better energy storage – is ok, but distorting the entire economy by INSTALLING wind power and solar power while they are still marvelously impractical is complete madness and leads to trillions wasted and misspent. With that kind of money you could develop fusion power – whether tokomak based, laser based, fusor based or cold fusion based – a 100 times over.

Strange that the graph here of the Central England Temperature record does not much resemble the data as shown here, by the people who produce the record.
Strange too that you plot a 25 year “trailing trend”, the physical meaning of which is not obvious – as you can see by the fact that it does not show your claimed rise from 1680 to 1740. If you were to take 25 year moving averages, or smooth using a filter with a 25 year window, you’d get something that looks very much like this.
Perhaps it’s better, though, not to smooth, not to filter, not to over- or under-interpret. Let’s just look at the ten hottest years in the CET. Here they are, in reverse order: 2007, 1989, 2003, 1995, 1997, 2002, 1949, 1990, 1999, 2006.
Anything about those years strike you as unusual? Nothing that makes you curious enough to seek an explanation?
“Since these warming periods were before the modern rise in CO2, greenhouse gases cannot have been responsible for those rises.”
This statement is very bizarre. Don’t you know when CO2 concentrations actually began to rise? Please read this, and revise your statement as necessary.

February 13, 2010 5:22 am

This is EXACTLY the question I (and thousands of other Joe Sixpacks like me) have been asking for years…from the very beginning. We have never gotten a reasonable answer. If there is nothing unusual going on, then what is all the fuss about? Or if we have been warmer in the past, then why is only modern warming “man made?” They have no answers for these most basic questions. It is good to see a scientist publicly asking as well.
We have been taught man is “bad” our whole lives in our schools. It is the mantra of the Left. Man must be controlled and throttled back. The entire AGW cult has more to do with that mindset than actual temperature observations.
But they cross the line when they try to tax us for this nonsense. And when they start taking away freedoms and economic opportunity (or economic sustainability) based on “carbon output”, it gets downright personal. Joe Sixpack is waking up to all kinds of nonsense…because he is not getting any answers to very basic questions like the one you have presented.

February 13, 2010 5:22 am

Thank you Willis. As ever, spot on.
In fact it was your description of your attempts to obtain information from the CRU that first got me interested in the whole AGW issue.
Then – like, I am sure, most other reasonably intelligent and genunely interested ‘ordinary’ people – I quickly became really angy with the degree of arrogance, rudeness, character assassination and general stupidity that even my most mild (and often self-deprecatory) enquiry would spark off in response.
I didn’t like it personally, but the positive upside of such behavior is that it can actually mobilize us ‘masses’ … we get indignant, we get upset and pissed off, and we are roused to start asking questions and digging deeper for answers.
And – only a very short time later – here we all are with the most salient question of all, the subject of your piece.
So thanks again.

If you take out UHI, manipulation, hiding data, hiding declines, cherry picking (Yamal), hockey stick illusions, data torture then the rise in temperatures over the last 35 odd years is utterly unremarkable and can be explained by natural variability.

Veronica (England)
February 13, 2010 5:26 am

That depends whether you think that trends of 0.25 C per century or 0.57 per century are significant, either statistically or practically. To close the loop, your article might imply that those rises are due to sunspots and so on, and show how we are climbing out of the last little ice age.
I suppose a deeper lesson to take is that individual data sets seem unremarkable, but the combined, averaged, adjusted and homogenised “global” temperature set is alarming. Maybe, as you have addressed many times on this webiste, that says less about the data, and more about the data processing.

It remains to be seen whether politicians like Ed Miliband (as Jabba the Cat hopes) are willing to grasp the undeniable logic Willis Eschenbach displays here, uprooting for good the withering tree of AGW lies and deception. European pols, having hitched their fates to the CO2 racket for decades, are stubbornly reluctant to face the truth.

There’s truth in what you say and there is a quote from Al Gore somewhere that confirms it… Human beings need something to believe in and unite behind. Religion did that for us for thousands of years. In the 20th century it tended to be political ideology. Now there is a basic human need to espouse a cause, and if religion and politics no longer wash with the educated and sophisticated masses, let environmentalism take their place.
I don’t think one needs to postulate a conspiracy. It is a natural instinct in people to have something to believe in, and politicians probably believed what they were hearing from climate scientists too, in the absence of any official contrary opinion. But no doubt politicians can make use of that instinct when it suits them.

Many thanks Willis. I myself use the CET to show that there simply is no significant warming to explain. It’s good to see it laid out in a different way. Anyone can look at the full data here http://hadobs.metoffice.com/hadcet/cetml1659on.dat Since the mid 1990s we have been hitting 10+ deg c (average England yearly temp). However, just like global, the temps don’t seem to be rising, but flattening. Unfortunately, with such a long record the Met Office often use it to say “warmest ever” or whatever. A running 10-year average is much more indicative, but the Met Office won’t use it for the obvious reason that it shows cooling since 2008.

TLM (04:28:52) :
The article would be fine if the fundamental question AGW proponents were asking was the cause of recent warming. Actually that is not what most of the AGW people are arguing. Their question is not “what has caused the recent warming” but “will pumping billions of tons of CO2 into the atmosphere cause future warming”.
That is a legitimate line of study – as yet with an inconclusive set of answers. I think the IPCC made a big mistake, and spoiled their argument badly, by trying to link the most recent period of warming to AGW.

Actually, the AGW argument changes, chameleon-like as it continually strives to adapt to the fact that the truth has a way of coming out eventually, despite their best efforts to squelch it. In any case, the argument that the rise in atmospheric C02 over the past century or so has been in any way responsible for the unremarkable rise in temperature has not been proven, let alone man’s measely 3% contribution, so the idea that it might cause future warming is just silly, and further study of this non-problem wasting $billions more idiotic.
The IPCC didn’t make a mistake; they were a mistake.

So, there were “casualties” but it was not my faultmy “friendly fire” was with good intentions, . How easy!, after the majority of goals intended by the scamers have been already reached, as for example the status of “dangerous substance” for an essential for organic life gas as CO2.

AMac
February 13, 2010 5:52 am

I don’t buy the argument made in this post.
The grounds for thinking that rising CO2 will, overall, lead to higher average surface temperatures are well estabished. See, e.g. Jeff Id’s treatments of the subject at “the Air Vent.”
“What is the sensitivity of climate to CO2?” “What are the delays before CO2’s effects are manifested?” These are important issues.
In recent time, say 1900 to 2010, temperatures have gone down at location X, stayed more or less the same at location Y, and risen at location Z. So stipulated.
Composite global records paint a picture of significant overall rises in average temperature. Unfortunately–as all here know–the quality of the data in these records is variable and in some cases poor. The quality of the metadata is worse.
Once the data are cleaned up and properly analyzed, what will the trend of the past centrury or so look like? My guess is that an unusual trend of rising temperature will remain–a slightly less steep version of what AGW Consensus advocates currently display.
At Lucia’s Blackboard, there’s a current thread for discussing how recordkeeping, archiving, sharing, and analysis can be improved.
Such projects are likely to be expensive in dollar amounts, though trivial as a percentage of GDP. Such money would be well-spent.
The notions that there are no causes for concern or investigation are unwarranted, in my opinion.

Alas, also, we can only ever make reasonable predictions about perfectly linear systems. They do not exist in the natural world. The reason that most ‘skeptics’ get so annoyed is not because we think that global warming does not exist, but that we do not know what the significance of that warming might be. Willis’ analysis and that of SteveMc, Ross Mc etc, demonstrate that historically the current trend of warming is not significant in human historical time but it may be in geological time or it may not be. Because of the shenanigans of Mann, Hansen, Briffa, Amman and so on, and so on, we have lost the last 20 years worth of knowledge and opportunity to better understand what we should have done and to have done it within our current economic budget.

True!
I am a (semi-retired) chemist and I decided for myself to determine whether or not carbon dioxide (CO2) and our carbon footprint is really to blame for climate change as claimed. I did this because I felt a bit guilty after watching Al Gore’s movie. But I could not find anything definitive that would prove to me that CO2 is to blame. In fact, I found that there is untruth in Al Gore’s story. A lot of CO2 is dissolved in cold water and comes out if the oceans get warmer. Cause and effect, get it? Smoking causes cancer but cancer does not cause smoking. But Al made it look from the past that our CO2 output must be the problem.
One would think that a person Al Gore’s caliber must have known that they were busy telling us an untruth or if he did not know then he must have realised by now. My question is;why does he not come out in the open and admit his mistake?

“Do we want to ignore climate change and risk losing all this?
There is a growing conviction that the cost of ignoring climate change will be far greater than of tackling it now, writes Geoffrey Lean.”
“Guess who just produced this pronouncement on how humanity is heating up the planet? “The basic science of the greenhouse effect is sound (ie more anthropogenic CO2 means more warming).”
Dr Rajendra Pachauri, the increasingly embattled chairman of the Intergovernmental Panel on Climate Change (IPCC)? Nope. Professor Phil Jones, under cross-examination from the inquiries into the notorious emails from his Climatic Research Unit at the University of East Anglia? Try again. Ed Miliband, the increasingly vocal Energy and Climate Change Secretary? Not even close.
Give up? It was none other than Dr Benny Peiser, the leading climate sceptic and director of Lord Lawson’s Global Warming Policy Foundation.
If you’re surprised, you shouldn’t be. For Lawson himself has said much the same, telling a parliamentary committee a couple of years ago that it was “fairly clear” that “man-made emissions, largely carbon dioxide, have almost certainly played a considerable part” in the warming of the globe.”
So as Dr. Jones is (partially at least) moving in one direction it is alleged that arch sceptics are moving the other way. You could not make it up. Life is stranger than fiction. And that in the Telegraph as James Delingpole is elsewhere declaring that the CRU independent enquiry team is anything but independent in its constitution:

“A lot of CO2 is dissolved in cold water and comes out if the oceans get warmer.”
This was an important process at the end of the last glaciation, but it does not explain the current rise in atmospheric CO2. Multiple independent lines of evidence point to this.
1) The Suess effect – the change in the atmosphere ratio of C12/C13 in the indicates c13 depleted anthropogenic sources rather than natural sources.
2) The decline in atmospheric O2 tracks the rise in CO2. This is expected only if the CO2 derives from combustion.
3) The oceans are undersaturated and are absorbing CO2 rather than releasing it.

February 13, 2010 6:38 am

TLM,
Theory states that increasing greenhouse gasses takes more and more added gases to cause equal temperature increment increases (approximately 1.2 degree C per doubling of CO2 from the theory) if there were no feedback effect. The rise in CO2 since 1850 would have caused more than half of the effect from a full doubling by this theory, but the actual rise was less than 0.8 degrees C (and may in fact have been much smaller due to selective use of data in cities). In addition, much if not all of the rise is likely a natural recovery from the LIA. This clearly refutes that there was a large positive feedback, and in fact supports a large negative feedback effect, reducing the CO2 gain effect. This implies that additional significant increases of CO2 would have little to no effect. There is nothing in the “pipeline” to cause a different outcome.

JM
February 13, 2010 6:40 am

I have to agree with a point made by Richard Telford. Just because something always happens doesn’t mean there is no value in scientific inquiry regarding it. If you asked someone a thousand years ago, they would have told you the sun revolved around the earth; it was obvious as you could see it with your own eyes. It wasn’t until much later that folks like Brahe, Kepler, Copernicus, and Galileo shook up the establishment.
That being said, real learning often happens when observations DON’T match theory, such as the case of planetary meanderings that required “epicycles” to explain their motion under the geocentric view of the universe, but under the heliocentric view of the solar system, weren’t required. A theory needs to explain and fit the data, not the other way around, something that Climate scientists need to keep in mind when they create models that don’t sufficiently match reality.

Just exactly what unusual, unexpected temperature anomaly are we trying to explain?
I still think that the compilation of increasing time windows in the icecore study that is put up here in Wattsup, is the best for stimulating the gray cells of the scientist on the street, and/or somebody who can read graphs.
It has two advantages:
a) a long humbling time perspective
b) the ice proxy temperatures are not involved,as far as I know, in climategates.
The regional records are useful too, as a second punch.

oldgifford
February 13, 2010 6:56 am

If you look at the CET temperature graph, the rate of increase between 1695-1733 was greater than the increase from 1962 – 2006. I chose minimums to maximums to try and compare apples with apples. Thus the rhetoric that “more rapid increase in temperatures than we have ever seen before” is perhaps not true. I did compare CET temperatures, not global temperatures, as prior to 1850 we only get proxies for global temperatures which have been proved to be unreliable. Overall the linear trend line shows about 1 degree warming over the period. If you look over the period 1930 to 2008 the change in anomaly based on the 1961- 1990 mean is very similar to the graph shown where the New Zealand NIWA discusses Temperature trends from raw data. This suggests that for at least one part of the southern hemisphere, the temperature trend is almost the same as that in our little bit of the northern hemisphere. Could one stretch this to suggest the way CRU and NOAA compute their global temperatures is perhaps not as good as they think it is?
I do not know where rw (05:21:15) got his data from. If I use a 30 year moving average on the CET data I see an approximate spread from 8.9 to 10.2, again just about 1 deg over the period.
The linear trend line is y = 0.0026x + 8.7261

rw,
It looks like the underlying data is the same but presented slightly differently. Your link to the met office data starts in 1780 and misses the late 17th century warming. Why would that be?
I also noticed the way the Met office have drawn the red line. At first glance it seems to show a suddenly rising temperature trend post 1976. When I looked more closely, I could see the trick. What they’ve done, is connect the lower temperature bars from the earliest time periods to the highest temperature bars in the post 1976 period. What you end up with is a line that shoots up after that time. Maybe there’s a reason for doing that, other than to imply an alarming rate of warming, but I can’t see what it could be.

February 13, 2010 6:58 am

TLM: it’s true that the AGHG modeling efforts began as a very legitimate way of answering the question you mention and others. But surely, if you have been paying attention, you have noticed that in the last few decades the media, fuelled by the IPCC and powerful scientific institutions, have led everybody to believe that the answer we’re seeking is the one Willis tries to answer. You have seen Al Gore’s movie or the IPCC pronouncements with hockey sticks at the background, haven’t you?

Brilliant work, Mr. Eschenbach. It is exactly what must be understood by all in the climate debate today. It is heartening to see that a chastened Phil Jones now admits that the science is not settled, that the Hockey Stick has been overthrown. Jones might be the crack in the wall that lets some light into the Alarmists’ fortress.

February 13, 2010 7:34 am

The two temp records from Ireland and England do show little temperature increases, as calculated by degrees per century.
Phil Jones wasn’t asked a question about temperature increases in degrees per century, based upon the worldwide record. Jones was asked and answered a different question about whether worldwide temperatures increased at similar rates in several different decadal time frames.
The rate of temperature increase can be statistically no different from each other for these decadal trends, while also having a worldwide temperature record increase at a greater amount per century than the two island records (Ireland and England). I would expect that sites strongly affected by ocean temps would warm more slowly than sites not so affected.
So if Jones had been asked about worldwide warming per century, I think his answer would have been a higher number than for the two island records. That would likely have been a legitimate answer, based upon the existing records, as interpreted by UAE, NASA, HADCRU, UK met office, etc.
The comeback to that would have been: yes, but have those records been adequately corrected for heat island effects, station movement, etc.?
So that is the question for science — what is the worldwide temperature trend when we have adequate coverage, have appropriate correction for heat island and local effects, and don’t use temperature records from several hundred miles away as a proxy for a missing station.

How many strategies do these “climate scientists” have?
1) manipulate the data wih steo function corrections
2) misrepresent the data; definition of Rural vs Urban, and with proxies, mix in instrument data where the proxy data doesn’t confomr to the theory (but real instrument data or value added?)
3) selectively exclude surface temperature stations where, presumably, the manipulation would be too obviously unjustified e.g. high latitude and high altitude.

From Richard Telford (06:36:37):
2) The decline in atmospheric O2 tracks the rise in CO2. This is expected only if the CO2 derives from combustion.
3) The oceans are undersaturated and are absorbing CO2 rather than releasing it.
I’m an engineer, not a chemist, but I I have some trouble with these statements.
With respect to 2), I’d like to see data or some other evidence that atmospheric O2 is declining. This doesn’t make any sense to be, as increasing atmospheric CO2 creates a more favorable environment for plant life, which in turn generates more O2. Also, the percentage of CO2 in the atmosphere is insignificant compared to the percentage of O2 so I don’t know how you could detect a “combustion signature” in atmospheric O2 anyway.
I’m really having trouble wrapping my mind around 3). The oceans may not be saturated, but they are more than likely in equilibrium (maybe I’m getting equilibrium and saturation confused). Chemistry class was a long time ago, but I remember that the solubility of gasses in liquids increases as the liquid temperature decreases. So, warmer oceans mean lower solubility. Wouldn’t the sea water give up some of the dissolved CO2 to adjust to the new equilibrium point? Looking at it another way, since the oceans aren’t saturated (i.e. capable of dissolving more CO2 at their current temperature than what is already there), why wouldn’t the atmospheric CO2 decline towards zero until saturation is reached? Obviously it doesn’t…the CO2 content simply adjusts to the new equilibrium point.
Statement 1) smells funny to me, also, but I don’t have the background to evaluate it thoroughly. I’d have to question what is so unique about the C12/C13 ratio from anthropogenic sources vs. natural sources.

Hi Willis
Great article (again)
I collect many of the historic temperature records here and have analysed some of them under the ‘articles’ section.
http://climatereason.com/LittleIceAgeThermometers/
I hope to add another 6 or so in the next week. If anyone can point me to pre 1850 records please let me know.
Like Willis I can see nothing at all out of the ordinary. Temperatures rose to the peak of the MWP, dropped sharply during the initial period of the LIA and have recovered ever since, but with numerous peaks and troughs.
The decade around 1730 appears remarkably similar to the last decade if contemporary observations and written records of that period are looked at in conjunction with the instrumental records.
Temperarures have risen slightly since the depths of the LIttle Ice Age. Who knew?
Thank our lucky stars we are living in a relatively benign period of climate-we don’t know what is around the corner.

One way to try and resurrect the CO2-warming hypothesis is to throw the ice core CO2 records partly under the bus. By assuming actual CO2 measurements from the 1800’s are accurate (rather than being ignored), the ice core CO2 proxy record can be adjusted to conform. Then, with the assumption that the ice core CO2 /measured CO2 correlation is maintained further back in time, and with additional adjustments, the CO2 variation in the past can be remade to support the CO2-warming hypothesis. I expect to see this line of reasoning start to show up in the next few years.

In the run-up to Copenhagen, prior to Climategate, we saw the “Three Legged Stool” of anthropogenic global climate change exposed for those capable of seeing it without any assistance from the bootleggers, the baptists or the media.
Leg 1: Zero carbon emissions (”350″, Gavin Schmidt)
Leg 2: Zero animal husbandry (Ban Ki Moon)
Leg 3: Population Controls (John Holdren, Cass Sunstein)
Seat: World Government (EU President, early Copenhagen draft)
The stool above would arguably have been the most expensive piece of truly ugly furniture in the history of the world, had it been assembled.
Perhaps we should all thank Phil Jones, Kevin Trenberth, Kieth Briffa, Tom Wigley, Mike Mann and the rest of the “Team” for their valuable assistance in preventing its assembly. We are truly blessed!

I think you just summed it up. In primitive tribes, when the volcano erupted, the shaman said the spirits were angry and must be appeased. Throw in a virgin. Every year that the volcano didn’t erupt was now proof that throwing in a virgin prevented eruptions. If the volcano DID erupt again, that was proof that they weren’t throwing in ENOUGH virgins, so go get more. The shaman wasn’t interested in determining the link, if any, between virgins and eruptions. He was interested in fitting the data to his theory so he could maintain his position as shaman.

I was summarily dismissed as a kook. I tried to debate those found there and was told I would not understand the Science..
I am an ENVIRONMENTALIST.. My DEGREES are in Environmental Sciences.. I have been in this field for 20 years and am considered one of the experts in the field of Environmental Compliance. I am one of few who hold International Certifications and have taught for years on the subject. I work Superfund sites.. I assist Industry and Educational facilities clean up and stop polluting the Environment.. Some of the worst polluters are “Scientists”. I work every day with these types trying to get them to stop pouring Lab Compounds down the drain.
I challenged them..
What do you do? Talk.. Theorize.. Talk some more…
All I got was abuse.. You see they can’t handle descent. These types want to shut you up and shut you down..
I did make one mistake I linked one source from WUWT and I was immediately jumped upon by everyone. They obviously do not much like those found here.
The issue I have with them (Deltoid and believers) is simple.. They feel they are above it all. They’re Scientist after all. They know more and are better therefore to decide what is best for the rest of us. The fundamental flaw with that thinking is GIGO.. Garbage In Garbage Out. If their fundamental basis for understanding AGW is flawed then their output would therefore be flawed as well. Their undeniable belief that others cannot understand the Science and are therefore deemed sub-human is what does in fact amaze me.

My point is made perfectly well by your simple statement of the fact. Did you in fact read the post?

Do you wish to understand why there should be the current ongoing change in the Earth’s climate that you yourself talk about?
“And Phil Jones has just admitted rates of temperature rise significantly similar to the ‘75-’98 rise three other times in the last century and a half. Where is the anthropogenic signature?”
An anthropogenic signature cannot be found merely in the gradient of a slope. Try reading the latest IPCC report to learn more. There’s a chapter on attributing climate change.

“Richard Telford (06:36:37) :
2) The decline in atmospheric O2 tracks the rise in CO2. This is expected only if the CO2 derives from combustion”
So a change in CO2 from 0.0284% to 0.0387% would drop Oxygen by 0.02%. Now, although nominally 20.95%, atmospheric O2 varies much more that CO2 does, during the day and night cycle and during the Winter/Summer cycle.
It is IMPOSSIBLE to measure a change in O2 levels over the last 50 years. Oxygen sensing technology is not good enough to measure O2 to three decimal places now. Medic’s and biochemists still crave an accurate, stable, device to measure O2 levels in gas or liquid. The fact is we cannot. Typically, oxygen levels are calibrated using H2O2 and catalase (or a Pt/Mn catalyst) as we have an extinction coefficient for H2O2.
Your statement is bollocks. No one can, or has, made measurements of atmospheric O2 to 0.005% over the last decade, never mind the 1960. The fact that O2 dissolves in water, about 250 uM at 15 degrees, also buggers up measurement as the level of water vapor is variable.
We cannot even transfer gasses or liquids between vessels with that precision. Using modern HPLC/FPLC valves we have a dead space in the order of 2 nl’s.
The Teflon used in the same valves (and that sit on the end of plungers of syringes) have a oxygen concentration of between 1 and 2 mM, the EXACT solubility is dependent on water vapor pressure. You can get other materials with lower O2 solubility, but there is always the O2/H2O competition for the void-space in the plastic matrix. There is no known material, that can be used as a plunger or valve housing, that does not have this property.
Transferring gases or liquids, with defined levels of O2 is essentially impossible. The mass action ratio of atmospheric oxygen is against you. All your materials are O2 saturated and can only be scrubbed chemically. O2 free gasses, that you buy, are not O2 free. You must used an inline scrubber to get rid of all the stuff in the line.
Many of us, who work with oxygen utilizing enzymes, have tried. The only way to measure O2, with precision, is to used myoglobin, sperm whale myoglobin or leg-haemoglobin and optical spectroscopy. You make deoxy-Mb (which is very, very hard) and add a know volume of O2 XuM, then observe the spectral change. I will get the O2 concentration +/- 2.5%, as I have done this before, you will get +/- 1000%.

Henry@ Richard Telford
Richard: You say:This was an important process at the end of the last glaciation, but it does not explain the current rise in atmospheric CO2. Multiple independent lines of evidence point to this.
1) The Suess effect – the change in the atmosphere ratio of C12/C13 in the indicates c13 depleted anthropogenic sources rather than natural sources.
2) The decline in atmospheric O2 tracks the rise in CO2. This is expected only if the CO2 derives from combustion.
3) The oceans are undersaturated and are absorbing CO2 rather
where were you at school? I remember one of the first tests was to prove that CO2 dissolves in water. That happens all the time in cold water, I think they call it sinks.
Where the water gets warmer the equilibrium of that chemical reaction shifts more back to the left and it comes out from the water into the atmosphere. The increase in CO2 was only 0.007% (70 ppm) since 1960. It did not make any measurable dent in the oxygen content. Most equipment cannot even measure the change in the oxygen content, it is too small.
Obviously I do not deny that the current rise of 70 ppm’s from 1960 in CO2 is manmade. But is it relevant?
I will agree with the warmists that CO2 traps heat (from earthshine 24hours per day) because of the absorption of CO2 in the 14-15um wavelength. I say, good, fine I believe you. But likewise there must be cooling because of various absorptions of CO2 in the range from 0-5 um (from sunshine 12 hours per day)! This cooling must logically take place everywhere where there is CO2 and where sunlight hits on the molecule regardless of height or pressure.. It is even so apparent that this happens that this radiation that caused this cooling can be measured as it reflects back from the moon. (we can prove this). So my question is: exactly how much cooling and how much warming is caused by the carbon dioxide?
So far no one has been able to show me the balance sheet i.e. exactly how much cooling and how much heating is caused by CO2.
I cannot find this research because it seems to me that such an simple observation of mine (ie. that CO2 also must cause cooling) has never been taken into account. Where the IPCC got its values from (for “forcings”) is a mystery to me but it is appears not to be based on actual measurements (research) that would produce a formula of some sorts. I think they were all just weighted values.The formula that Svante Arhenius had is completely wrong.

The Met Office version of the CET you reference is manipulated by cutting off the first century of records and by using 1961-1990 (the HadCRU standard) as the reference period.
Additionally the modern record has been adjusted for UHI. If other examples of this process are any guide, this would entail lowering past temperatures and raising modern ones.
The Met Office, I am sure, will tell us that this manipulation is not intended to make the data appear more alarming.

That is one of the oldest statistical tricks in the book. It is based on the fact that there is no really satisfactory way to extend a smooth (except a trailing smooth) to the end of a data set. One alternative used in a number of statistical software packages is to tack on the first data points after the last and use these for the smooth. This is only appropriate for data without a trend. Since Met Office can hardly believe that there is no trend in the CET this is deliberate deception in my opinion, particularly as they don’t use the whole data set, but rather start it at a low point, which will inflate the trend at the end.
In other words, cherrypicking and faking as usual. By the way it was not the Met Office that created the CET, it was Gordon Manley, rw (05:21:15) please take note.

Partial excerpt:
The National Cattlemen’s Beef Association issued a news release Friday afternoon stating that the group had joined other associations in petitioning EPA Administrator Lisa Jackson to reconsider the EPA finding that greenhouse gas emissions are an endangerment to public health. According to the release, the petition “is based upon information uncovered during the recent ‘climategate’ scandal, which seriously calls into question the scientific validity behind EPA’s finding.”
“It’s become evident that EPA’s endangerment finding may be based on flawed data,” said Tamara Thies, NCBA chief environmental counsel. “The fact that EPA did not choose to reconsider its finding after the extent of the climategate scandal was revealed publicly is perplexing to say the least; ignoring climategate will not make it go away.”
NCBA further states that “The petition asks EPA to convene a proceeding for reconsideration to thoroughly reevaluate EPA’s heavy reliance upon the Intergovernmental Panel on Climate Change (IPCC) reports which have been called into fundamental question. As part of this proceeding, the petition asks that EPA: prepare a complete and objective record for the reconsideration proceeding which contains all the relevant scientific data, studies, and viewpoints and is cleansed of questionable or one-sided data; obtain and fully disclose all computer programs, data and algorithms used to “homogenize” all temperature records upon which EPA relies; subject the temperature records and programs to an independent review by qualified and objective scientists and statisticians; and determine whether or not there is any statistically valid demonstration of unprecedented global warming over the last century.”
Finally, NCBA and the petitioners are requesting a stay in any further regulatory actions or rulemakings which are based upon the endangerment finding until these fundamental requirements of sound science, legal due process, and valid administrative rulemakings are completed.

The four horsemen of the climate apocalypse are: Jones, Hansen, Pachauri and Gore.
The only way they can be slain is by public self-confession of the truth – there is no other way our gullible political leaders are going to accept the facts – so, one down, three to go.
The other three are going to be tougher nuts to crack. From a financial point of view, they have much more to lose and they are also surrounded by very much more powerful fact spinning organisations.
So to paraphrase Churchill’s great statement: ” Never in the field of human science has so much almost been lost as result of the actions of so few.” So far, the loss is ‘only’ billions, if Copenhagen had succeeded it would have been many trillions – all to achieve absolutely nothing.

February 13, 2010 9:31 am

You say, “Jones also makes the interesting argument in the interview that the reason he believes that recent warming is anthropogenic (human-caused) is because climate models can’t replicate it … in other words, he has absolutely no evidence at all, he just has the undeniable fact that our current crop of climate models can’t model the climate. Seems to me like that’s a problem with the models rather than a problem with the climate, but hey, what do I know, I was born yesterday …”
I agree absolutely. I said this in my blog here (http://sunriseconsulting.blogspot.com/2010/02/illuminating-interview-on-uk-channel-4.html) on 2nd February as a result of the interview Prof Bob Watson gave to Channel 4 news. The only evidence they have is that they can’t explain the warming without human causes. Hence they need to keep hiding anything that might start to explain it.
But your post is highly significant. For Phil Jones to say that current warming is not statistically different from previous warming periods is surely an admission of defeat! What else needs to be said? I hope this reaches the MSM.

From a hardcore AGW skeptic: The Willis argument is too strongly made and does miss the essence of science: Science is not circumscribed in its subject matter to include only anomalies. Regularities can also be important. That the sun rises daily in the morning was not an easy issue for the human race. It took good science in the era of Galeleo, Newton, Copernicus, Kepler, et al to overcome the Ptolemaic explanation. the power of science to account for the commonplace lends credence to its explanations of the strange, arcane, and remote.
There is an anomalie in our era: The rising production of CO2 by humans. Good science includes considering possible effects of our CO2 production. It is reassuring that our science shows that humans produce only a few percent of the annual budget for CO2 production on Earth, and that CO2 is a minor component of Earth’s atmospheres GHG’s. Furthermore, the recent failure of global temperatures, however poorly measured, to show a steady correlation with rising CO2 level is further reassurance that CO2-caused problems are or (ought to be) low on the list of human concerns (echoing Lonborg here). Good science plays a role here and ought to be encouraged.

February 13, 2010 9:36 am

Phil Jones said: “Temperature data for the period 1860-1880 are more uncertain, because of sparser coverage, than for later periods in the 20th Century. The 1860-1880 period is also only 21 years in length.”
So why are stations being removed from the data set all over the world by GHCN??

If anyone from YouGov (yougov.co.uk) is looking in here, can I ask: what is the point of having a survey in which one question offers only a choice between either “Climate change is a myth” or “Climate change is the greatest threat to the world”? The respondent had to plot their answer between 1 (greatest threat) and 10 (myth).
There was no way to record a response of: “Neither”.
There was no way of saying, as I believe, that climate change is happening but the climate has always changed, and in the past CO2 and global temperatures have been higher than they are now, and the planet is still here supporting life (so, no, not the greatest threat).
So the – misleading – published result will be: either most people think it is a myth or the greatest threat. Talk about deliberately skewing the result. Is YouGov run by AGWers – I think we should be told.

Instead, we have used the money to make some people very rich and given them lots of prestige. The money has not been wasted, it has been misspent. It has been used to do something. In fact that something has involved the ruin of science, and we may have to spend a similar amount rebuilding science’s shattered image…

Of course, getting the story out is almost impossible when you have politicians like Obama tasking NOAA to watch the climate and give companies climate change advice, as if companies really have to plan for climate change – implicitly indicating climate change to be a critical factor (now ) in a business plan?
And now Obama wants a “global warming agency” to study the problem, apparently blatant enough in its goals to not call it a “climate change agency” (I admit not to know what the name will eventually be, it was discussed as the former).
Politicians do not deal in reality, just the fabrications that they can get other people to recognize as vague possibilities. Obama has no interest in the facts – what he needs is huge new revenue streams to feed in huge new government.

Re: Richard Telford (05:51:54) and Allan M (06:58:15):
I agree that it’s too narrow to say that science tries to explain only anomalies (and that it’s far too narrow to say that science tries to explain only change). Yet the anomaly view has some pedigree. C.S. Peirce held that all real inquiry is a struggle that begins with surprising observations. In this view, prediction is entirely a step in the process of testing an explanatory hypothesis. That view helpfully anchors prediction in efforts to resolve issues in observation and theory. But it seems to me that prediction can be a primary motivation which can send one looking for discrepancies among observations and theories – that anchor is not automatically lost when prediction is the main goal.
I can see four general inquiry-stimulating “unsettlings” at least:
1. Bafflement at the complex or complicated. E.g.: What _has_ happened?
2. Surprise at the anomalous, the seemingly unlikely. E.g: What _is_ happening?
3. Suspense over the vague. E.g.: What’s _going to_ happen? (Prediction.)
4. Hesitancy about the unfamiliar, the uncolligated, that whose lessons have not been learnt. E.g.: What _would_ happen (if…)?
And searches at least four kinds of answer: In what light would the phenomenon seem (1) simpler? (2) more usual or normal? (3) clearer, more significant or informative? and (4) deeper, less nontrivial? – each of which can be helpful in any of the above questions.
However that is all very general. If there is no major anomaly in the temperatures, then the questions which would be raised by such an anomaly are obviously not raised. That is not to say that climate raises no questions and is not something about which to wonder and worry. One thing C.S. Peirce seemed right about: questions normally need to be genuine, producing really motivated struggle for answers, in order to have a chance of leading to genuine, scientifically fruitful and sound research.

Climate models don’t include the effect of clouds in their operation, so it’s not surprising they aren’t reliable and don’t provide answers that make sense. That only confirms that the climate models are not to be relied on, It’s a bit of a leap to say it’s down to man. That sort of reasoning went out with alchemy.

Mr. Eschenbach
If one separates summer and winter trends, than picture becomes even simpler. Nothing extraordinary I agree.
Here is my personal take and a contribution to CET debate (I would be interested to know what you make of it).
Recorded UK temperatures have oscillated, during last 300 years with a period of about 50+ years. While in the long term winters’ temps have risen (0.4C/century), summers’ have hardly moved (0.05C/century).
http://www.vukcevic.talktalk.net/CETt.htm
The bottom half of the graph shows de-trended temp changes (upward trend removed from the data). It is obvious that both summer and winter temperatures show similar natural oscillations (sometime in phase and sometime out of phase – that is another story) plus linear (but different) upward trends, which I think are due to a slow recovery from the Little Ice Age.
This corresponds well with plenty of the anecdotal evidence of the very cold winters (frozen Thames etc), but very little about unusually cool summers.
The graph also shows that UK currently may be entering the ‘next 50 year’ cooling period. If so the government would do well to start concerning itself with reliability of its energy supplies.

You may be interested in this page by a certain Phil Jones which gives more information on the CET set and also shows the record for the four seasons as well. This bears little resemblance to the plot referred to by RW, which is on the Hadley Centre web site.
It is ironic that Phil Jones’ piece starts off: “Global temperatures are rising and have now reached unprecedented levels compared to the last millennium”
I notice that “The series starts in 1659. Developed by Manley (1974), and enhanced by Parker et al. (1992) who added the daily series back to 1772 …”. Now am I being overly sensitive when I see that the series was enhanced by Parker et al .
Perhaps somebody who knows what they are talking about could comment on what has been done to the raw data as explained in the Parker paper ( http://badc.nerc.ac.uk/data/cet/Parker_etalIJOC1992_dailyCET.pdf ).

Re: tfp (Feb 13 09:52),
You dropped a decimal point somewhere. If the trend were in fact your 3 C/century, then the temperature change from 1800 to 2009 would be about 6 C. Instead it’s about 0.5 C. My guess is that the x axis is in decimal years and so your slope is 2.58E-03 C/year not month. I’ve made worse mistakes.

It is clear from his comment that it’s a deep mistake in his thinking, oh wait a moment, that’s not a rational statement of a cause and effect based upon evidence or facts… it’s a “belief”… Phil Jones admitted that he “believes that recent warming is anthropogenic (human-caused) is because climate models can’t replicate it”. Ouch. So it’s his default explanation based SOLELY upon “belief” that humans cause global warming! No wonder he never wanted to address any of the criticism for he realized that it’s belief not tested by the scientific method… and when it does come under scrutiny a journalist digs it out and Phil Jones splatters himself as a “humans are the cause religious believer with a scientifically unsupported belief” rather than as a serious scientist who lets the science overrule his personal biases that his “beliefs” would create.
This is why beliefs have no place in science – they interfere with the actual process of the scientific method. Peer review is supposed to dig out these personal biases but that failed in this case due to private belief driven personal agendas “to save the world” when there was and has yet to be any evidence presented that there is any danger as claimed.
“Extraordinary claims require extraordinary evidence.” – Carl Sagan.
So far all we gotten are the extraordinary claims and not even ordinary standards of evidence. Sad, really sad and they claim climate science a “science”. What it is is a major fail. Professor Phil Jones you get an “F” and are hereby booted out of science class for letting your “beliefs” drive science and public policy without the HARD evidence required. I think there is a tab, in the many multiple of billions of dollars, that needs to be paid back. Let’s see… what will your earnings for the rest of your life be? That’s a start. Now who collaborated with you in the propagation of your “belief based cult science”? Let’s garnishee their lifetime wages too… oh and Maurice Strong hiding out in Communist China… hmmmm… Al Gore got Blood & Gore on his hands… let’s recover the funds earned from An Inconvenient Truth to pay back some of the public monies that were wasted on this belief without hard evidence of Phil Jones. Ah, Michael Mann how much do you make… on it goes… oh you too David Suzuki, cough up the dough to recoup the public funds… that includes your investments and income from The Nature of Things.
Belief based science is not science, it’s religion. Real scientists learn to recognize their beliefs and bias and set them aside going with the evidence to prove or disprove various hypothesis. In so doing they are being true to the Objective Reality of Nature and to the public purse and the tax payers who support their research.
Hypothesis Lock In is a scientific crime. Yes, scientists should pursue various hypotheses to obtain evidence or counter evidence but when you ignore the counter evidence at what point to you stop being a scientist and instead become a member of the clergy pushing a belief against hard counter evidence? As soon as you ignore counter evidence and don’t give it and those presenting it a fair evaluation and consideration you’ve crossed that line. Certainly by the time you’re yelling “denier” and “skeptic” other invective personal attacks you’re not longer a scientist interested in the scientific method, you’re some weird form of mutant high priest clergy member of a cult group. In other words, you’ve become a really bad scientist pushing.
We need evidence. Hard, verifiable evidence. That is how we separate the bogus hypothesis from hypotheses that to various degrees of accuracy represent what is really going on in the Objective Reality of Nature.
We need evidence. Hard, verifiable evidence. Audible and repeatable by anyone with the skills. Open for all to see. Any science funded by the public OR that public policy is based upon MUST be Open Source Science. Write your public representatives and urge them to make new laws FORCING scientists to comply with the most open standards of Open Source Science: all data, all notes, all tapes, all videos, all conversations, all emails, all letters, all funding sources, all participants, all witnesses, all analysis methods performed including those that didn’t work out, all math used, all spreadsheets, all software systems used, all data files, all program files, all program logs, all versions of their papers, all reviewers notes for any published or not-published papers, all conclusions, all conclusions that they dropped, …, everything they did! That’s to permit serious auditing! No more than a six month delay on anything prior to publication and after publication no delays at all. If they want public funding monies or to have public policy set by their alleged scientific conclusions they need to show their work just like everyone had to in high school algebra and science class! They are supposed to be professionals, so let them prove that too along with their claims and conclusions!

I believe the “excitement of the public” is actually better described as panic (that is, for those who care anything at all about the matter).

I have a strong feeling that their reaction will be outright anger -if and when they realize they’ve been duped- and a total ‘turn-off’ to many (if not all) “science” matters in future. When you say, “It can be turned toward “good”.”, I say that is very unlikely.

It’s great that the careful inspection of a few trees can provide assurance that the forest is not endangered but a glance at the forest provides the same assurance. The geological time history of the climate is available and indicates our current epoch is almost as cold as it ever gets and has CO2 levels about as low as they ever get. Most of the time during the last billion years the flora were lush and the fauna plentiful at much higher temperatures and CO2 levels. What exactly do we have to fear if we were to return to those conditions? Surely it would take hundreds of years at the least so no one would drown from rising sea levels. I fear a return to glaciation much more.

Even if one was to accept the IPCC’s claim of a 0.6 deg C rise in global average temperature over the past century (and there is sufficient reason to be skeptical of this claim, given the absence of impartiality within the IPCC ), this is an increase from 286.4 deg K to 287.0 deg K over the past century, which is a 0.2095% increase in temperature on the Kelvin temperature scale. This also represents a 0.8406% increase in the black body radiation. If you were to increase the setting of your home’s thermostat in the winter, from 21.0 deg C, and increase it by the same percentage, I doubt that you would even notice the difference (the end result would be 21.62 deg C). The AGW alarmists would have the entire population of the earth believing that this tiny increase in the heat energy of the earth system is responsible for any and all extreme weather events, you name it, all sorts of events are blamed on global warming, and they say man is responsible. If there is a reduction in the annual seasonal snowfall, it is due to global warming, but a major snow storm is also due to global warming, according to the alarmists. (Calling Bill Nye, the science guy!) The math presented above says they are wrong. When AGW alarmists take the position that is equivalent to “Heads I win, tails you lose”, you know you are dealing with a group of propagandists and con-artists.

This is really twisting what Phil Jones is saying. Yes, the rate of warming in 1910-40 is similar to recent. No surprises there.
But in saying that 1860-1880 is not statistically different, he carefully explains why. It’s a short period of time, so the trend already has large error bars. And there was a lot of measurement uncertainty. So saying that the difference is not statistically different is not saying that they are similar, It’s saying that the trend 1860-1880 is not well enough measured to differentiate it.

Any degree of temperature change, regardless of the cause, will have a climate zone affect. Meaning that anomalies may be biased depending on placement of sensors. However, with sufficient sensors placed in open spaces within each climate zone on a world-wide basis, and accurately measured over a 200 year period, a more accurate assessment of climate change can be made that will either show a direct correlation with natural climate change factors, or will go against natural climate change factors. As in: The temperature will be the reverse of what is expected given the concomitant natural climate drivers and systems. The temperature will far overshoot the normal range for that climate zone, etc.
The reason for the 200 year period is to take into account the rare concurrence of natural climate oscillations that cause greater temperature change than under more mixed conditions.
Till that data is in, we shouldn’t pollute with sooty, dirty brown belching emissions, garbage strewn about, or return to lax controls on hazardous products like mercury.

Guest Post by Willis Eschenbach
Science is what we use to explain anomalies, to elucidate mysteries, to shed light on unexplained occurrences. For example, there is no great need for a scientific explanation of the sun rising in the morning. If one day the sun were to rise in the afternoon, however, that is an anomaly which would definitely require a scientific explanation. But there is no need to explain the normal everyday occurrences. We don’t need a new understanding if there is nothing new to understand.
PLM – I love your post Willis and will forward it to family who normally are persuaded by the “news” to “believe” in AGW. Howver, I’ll take the challenge! Many seemingly mundane occurrences such as a “rising” morning sun have caused extreme behavior by humans. Define “rising” – Relative to ones time/space. The investigation into the “rising” sun had a lot to deal with the aforementioned Copernicus, Galileo, etc. and much turmoil including Al Gore et al’s infatuation with “flat earthers”.
Anyway, an appropriate ongoing investigation into climate should be pursued, not the hysterical political efforts taking place even after Climategate. I have contacted my representative politicians to quash the CLIMATE SERVICE being pushed by the President. Last I looked our grandchildren’s credit was used up – especially for cronyism wasteful (misspending) redistribution of future financial credit.

Great piece, Willis. I would consider it a dagger to the AGW theory, except for the fact that the hypothesis is somewhat like Rasputin – it will not die very easily.
Everybody else – here is what Willis said when he started:
Science is what we use to explain anomalies, to elucidate mysteries, to shed light on unexplained occurrences.
Now, how is that statement “narrow” or “anti-science” (an accusation made by one blogger on this particular post)? The entire world was, at one time, unexplained and unknown to us. So shedding light on unexplained occurrences seems to me to be exactly what science has done over the millenia. Implicit in the statement, too, is the fact that in order to explain anomalies, one must know what is ordinary, what is natural or normal in terms of existing conditions.
The Carl Sagan quote posted by pwl above says it all. Extraordinary claims DO require extraordinary evidence. And nothing that I have seen to date tells me that we are experiencing anything other than natural variation. We need to understand a LOT more about climate, a LOT more, before we can decide that the “anomalies” we see are extraordinary or not. We have only begun to scratch the surface of this subject, I believe. Any scientist who tries to tell me otherwise is barking up the wrong tree.

His premise – you use science to study change – is strained. Actually it’s probably a dud. Climate is worthy of study, whether significant anomalies are being observed at the moment. Not that AGW isn’t just a tempest in a tea cup, so to speak. Maybe more like a squall in a soup bowl.

I want to see a poll with the following question answered:
Do you believe scientists have proven that human CO2 emissions will result in future climate changes that are significantly more dangerous to humans than the future climate changes that will occur without human CO2 emissions?
I would bet that more than 60% would answer no and that should drive the political debate — meaning, no one thinks we should do anything about CO2 emissions.

Measurements of atmospheric Oxygen concentrations (actually O2/N2 ratio) are avaliable for about the last 20 years from http://bluemoon.ucsd.edu/images/ALLo.pdf This is Ralph Keelings’ group’s data. His PhD thesis from 1988 is online, and a Nature article http://www.nature.com/nature/journal/v358/n6389/abs/358723a0.html describes some of the early results.
All things being equal, increasing the temperature of some water will cause it to outgass. But if you increase the partial pressure of the gas in the atmosphere, you can overcome this tendency and dissolve more gas. There wouldn’t be concern about ocean acidification if CO2 was not being absorbed by the oceans.
Photosysnthesis preferentially uses 12C over 13C, resulting in plant material, and hence fossil fuels, that are depleted in 13C, and an atmosphere enriched in 13C. When fossil fuels are burnt, the atmosphere becomes less enriched in 13C. There is a figure at http://cdiac.ornl.gov/trends/co2/iso-sio/graphics/isomlogr.jpg

Where is the unusual occurrence that we are spending billions of dollars trying to explain?
Classic error.
You seem to think AGW theory exists to explain recent warming.
That is wrong.
AGW theory arises from (first) an understanding of the radiation properties of the CO2 atom and (second) the interactions of these physical properties in a broader climatic system. Warming is the prediction that results from AGW theory.

“the ‘magic’ CO2 tax.” (and almost all climate change “action”) is a solution in search of a problem.
It is a case of world class busy bodies not having anything better to do with their time, for the most part. Whatever scientific realities exist (and can be the basis of legitimate and rational scientific discussion), the political cult left them behind years ago and is now a self-sustaining entity. There’s a lot to be said for the fact that all this gained traction immediately after the final* and complete discrediting of the Marxist/socialist world view. Those people had to go somewhere and do something. The means have changed but the basic goal has not.
*final – well, it’s sure to rear its ugly head again, as all bad ideas eventually come back around, so final is said advisedly

Should I have supplied citations? I don’t need to. That’s the beauty of being a skeptic, I don’t have to prove you are wrong, just show that your argument isn’t convincing. I can sit back and proclaim “I don’t believe you. Show me the evidence”, and let you do all the hard work.

I found some other results of this study interesting. One such involved the analysis of time lags. The authors found that in 98.5% of their regressions, CO2 lagged temperature. There will undoubtedly be those who interpret this as evidence that CO2 cannot be a driver of temperature, a common misinterpretation of the ice core record
————–

In Australia its the long term drought period we are now expereincing that is mostly used to “prove” climate change. Yet even though we generally only have long term data for up to 150 years, that data shows that based on 1, 2, 3, 4, 5 and 10 year rolling averages the period up to around 1906 was as dry or drier than the current period.
And in “panic” government here have spent $billions on desalination plants that will consume incredible amounts of CO2 producing energy and increase our cost of water by 3-6 times!
Note however that I still support initiatives to reduce energy consumption in first world countries because it is my view we are being excessive in energy consumption

Do you mean the one in the Asian Times blog?
I hope I will be alright one way or another. Hope springs eternal in the human heart, after all.
We have lived through inflation of 30% 30 and 40 years ago, and survived. The problem now is that the government cannot print money and fool the fools as happened then.
I do not know about the content of the e-mail. I think it is more mismanagement than corruption per se, and selling political influence and socialism to the masses. We have three more times the civil servants we need because of this. In addition we have an enormous military burden: because of the belligerence of Turkey which continually threatens our islands and neighboring lands we are forced to keep a large army ( more civil servants) and continuously buy weapons. This last is the reason of the EU turning a blind eye in the past to excess borrowing since we buy from Germany and France.
The basic reason for the mess is the world economic crisis which brought forth the weakness of the greek economy.
It is true that people are averse to paying taxes, everybody. In polls 80% are saying they are willing to help solve the problem but when it comes to paying taxes, it is the other fellow who should do it. Tax evasion is an olympic game.
So, as it used to be in the former soviet republics, a lot of civil servants moonlight in other jobs not registered in the open economy : from helping in their wife’s shop to tutoring or driving a taxi while holding down another job, the majority of greeks are hard working, but hiding income from taxes.
It will take sometime to computerize everything so as to catch most of this.

Even Willis agrees that there is recent warming: “So in fact, according to Phil Jones (who strongly believes in the AGW hypothesis) there is nothing unusual about the recent warming either.”

February 13, 2010 1:56 pm

Willis Eschenbach (12:27:12) : Thanks Willis. The semantics used by the “Climate Change” community has always confounded me. Your article goes straight to the heart of the problem, with the mis-use of the word anomoly, when we are actually discusing temperature variations. The dictionary defines an anomaly as: “Any occurrence or object that is strange, unusual, or unique. It can also mean a discrepancy or deviation from an established rule or trend”. As no rules or trends confirm the present existance of any strange, unusual or unique variations to the Earth’s atmospheric temperature, there are no anomolies, only misunderstandings, mistakes or mischievousness. For example, the dramatic jump in Global Temperature Anomoly, reported by UAH for Jan 2010 – up by 0.44 degC in a month. Now that was an “Anomaly”! At that rate, we’ll all be toast by Christmas!!
Also, the Earth does not have a “climate”. If it does, I would like to hear the definition from someone. Astronomers never refer to the “climate” of planets”, only to their atmospheric properties. I would venture to suggest that the USA does not have a climate – or Britain or Australia or most countries.
P.S. Willis: the weather records for the USA (Eastern seaboards), including the records kept by Charles Peirce of Philadelphia, to date cover 220 years. Canada, Australia and NZ have records going back 150 years or so.

s. lindsey (08:09:36) :
I have been on Tim’s Website Deltoid and engaged those found there with some irrefutable facts..
I got called a Moron, Stupid, Idiot, Denier, a buffoon, a denier of Science and on and on..
………
I challenged them.. What do you do? Talk.. Theorize.. Talk some more…
All I got was abuse.. You see they can’t handle dissent. These types want to shut you up and shut you down..
The issue I have with them (Deltoid and believers) is simple.. They feel they are above it all. … Their undeniable belief that others cannot understand the Science and are therefore deemed sub-human is what does in fact amaze me.

They have put themselves in a position where they can’t back down from a bet. That’s the comeback you should make to their sneers, to put them in their place: Put up or shut up. Here’s a comment I posted a couple of days ago in response to someone who had run into a similar bunch of know-it-alls:

I suggest that you challenge them to make a bet. (Conclude your challenge with “puck/puck/puck” to encourage them to get cracking.)
There are three bets they can make on how warm 2010 will be (based on GISStemp’s online figures), at the well-known, Dublin-based event prediction site https://www.intrade.com (Click on Markets → Climate & Weather → Global Temperature). They are:
Will 2010 be THE warmest year on record? (32% chance)
Will 2010 be warmer than 2009? (31% chance)
Will 2010 be one of the five warmest years on record? (66% chance)
At least three noted warmists have given a “better than likely” estimate of the first question (and thus the second by implication, because 209 was close to being the warmest), and from that I infer that they are virtually certain that 2010 will not be noticeably cooler than recent years (the third question). Since the odds automatically adjust as punters place their bets on one side or the other, they and their followers seem not to have backed up their opinions with cash. The skeptics seem to be more willing to put their money where their mouth is.
There are also six other bets on future global temperature as well, having to do with the temperatures in the years 2011 through 2019. These haven’t yet attracted any betting and only a few bids and offers, so the odds are a guess. But a bettor can make a bid or offer he thinks is reasonable and wait for someone to take him up on it.
It’s a bit of a hassle to get registered, set up an account, learn the bidding process, figure out how to navigate the site, etc. but it’s much more practical than trying to arrange a one-on-one bet with a distant, antagonistic stranger. (Other problems: who will hold the bet? Who will adjudicate disputes? What if one bettor wants to bet on one of the nine propositions mentioned above and the other wants to bet on another?) And Intrade has the advantage of allowing a bettor to exit his bet if he changes his mind or there’s an emergency, or if he thinks the odds have become unreasonably biased in his favor so that the bet is no longer attractive (rational).

Ron Broberg (12:07:02) :
…the CO2 atom…

*snicker*
AGW CO2 theories arose from having some data that could indicate warming, noticing CO2 levels were going up, and trying to link the two. The basic radiative properties of the CO2 molecule may have been studied in the lab, but it was not understood how it behaves in the real world, in the atmosphere, and those properties alone cannot account for the warming. Thus AGW CO2 theories rely on “positive feedback mechanisms” involving H2O, which have not been demonstrated to exist but AGW CO2 theories need them therefore their existence is assumed and cited as fact, whatever they are.
The “A” comes from assigning blame for recent warming to mankind, thus gaining favor among the eco-crowd and making it a political issue. Which was bad science. For proper science, the concept should have been worked on until it could say for X atmospheric concentration of CO2 there should be Y global average temperature. Near as I can tell, this has never been done, and real research is showing they are quite a long way from doing so, if it is at all possible. What they do have is computer models using what they think they know that show what might happen if they are right. If they ever do get to X yields Y, then they can figure out how much of the recent CO2 increase is due to mankind, note how much added temperature this has yielded, and let the assorted political interests do with it as they will. And that would be correct and proper science.
(…)
You seem to think AGW theory exists to
explain recent warming.
(…)Warming is the prediction that results from AGW theory.

Chicken and the egg logic. Noticing warming lead to AGW CO2 theories, which try to explain why there was warming and why there will be more. Warming to AGW CO2 theories to warming. If they could not explain recent warming then they would not exist, as they are expected to hindcast to verify their ability to forecast.
Well, if one accepts they exist for reasons other than generating funding.

Two comments:
1. The question of whether “it is accepted that CO2 will have a warming effect” is open until all the feedbacks are fully understood. There is not even any reason I have seen to believe that the feedbacks are constant – they may well be very variable.
2. The question of whether decadal temperature trends are statistically distinguishable is meaningless when there are major autocorrelation and long-term time series factors involved. All that can reasonably be said is that common sense tells us from the historic charts that there is a lot going on we don’t understand and that nothing much seems to have changed recently.

What is evident from my plot is that the period from 1985 to present does not (yet !!) conform to the general linear trend. Adding a trend line to 1985 to present gives a warming of 4.4degC/century (got it right this time I think)
http://img20.imageshack.us/img20/7086/cet.png
The current trend in CET is negative so there is a possibility that in a decade or so there will be a return to the .3C/100year average. But can we wait to find out?

Please excuse my lack of familiarity with the detail of this thread, but my response to Willis’ perceptive post is that there is indeed a valid question here requiring scientific research. The question is: as ~ 30% of the current atmospheric CO2 load, i.e. ~ 105ppmv, is of anthropogenic origin, why are we not seeing a uniquely definable global mean surface temperature warming signature indicative of this, noting that signfiicant anthopogenic CO2 addition commenced in circa 1850?
A closely reasoned and dispassionate analysis of the data supporting the 30% anthropogenic CO2 addition since 1850 is based on DELC13 signatures of volcanic vs vegetation vs petroleum vs methane, with the analysis found here
http://www.ferdinand-engelbeen.be/klimaat/co2_measurements.html
Note also that the DELC13 data also indicate that ~ 55% of the total anthropogenic emission load is now resident in the biosphere and oceans. I found Ferdinand’s analysis compelling and robust.

Same error Willis made.
AGW predicts warming.
It wasn’t invented to explain it.
Warming did not lead to AGW CO2 theories. CO2 warming theories were advanced in the 19th Century. The issue was again addressed in 30’s and 50’s by guys like Callendar and Plass.
Modern AGW theories started their run in the 1970s – so their predictions predate the “recent warming” trend that Willis alluded to above. At least, come before a statistically significant trend was present.

For example, you have models that have large error bars and the measurements are “consistent” with them. meaning you cant reject the Null.

Of course, there are peer reviewed papers to the contrary, that the current warming isanomalous, and needs explaining. But the statistics (used in them) are questionable, and there are other papers to the contrary. Which brings us back to where you are.

Willis Eschenbach dismissed rw’s query about the 25 year trailing trend with the put down, “If you don’t know what a 25 year trailing trend is, I fear this is not the place for an explanation.”
On the contrary, this is precisely the place to explain what you mean by it. Including the “I filtered it with a 17 year window” statement.
My understanding of it is that a value on your ” jagged black line” is computed from monthly values from the preceding 25 years, (though I don’t see how the 17 year window fits into this). This understanding is supported by your graph, where the start of your jagged black line is 1685 and the start of your blue monthly values is 1660, 25 years earlier, as far as can be judged.
It is never possible to adequately compare smoothed data from the end of a time series with that from the interior of the graph, because the final values of the smoothed graph require data from years that have not yet occurred. Using such a long 25 trailing trend exacerbates this problem. Since you were specifically wanting to compare recent rates of warming with earlier periods would it not have been better to use a much shorter period of time for the smoothing?

Yes, you did. Although it’s a common misunderstanding. For glacial/interglacial transitions, CO2 would act as an amplifier, not the principle driver, of temperature change. The same goes for albedo change (the fraction of incoming sunlight that is reflected rather than absorbed) due to the change in ice area at the poles. Would you accept the argument that a change in albedo has no effect on temperature because the temperature starts to go up before the ice melts?

Jones also makes the interesting argument in the interview that the reason he believes that recent warming is anthropogenic (human-caused) is because climate models can’t replicate it … in other words, he has absolutely no evidence at all, he just has the undeniable fact that our current crop of climate models can’t model the climate. Seems to me like that’s a problem with the models rather than a problem with the climate, but hey, what do I know, I was born yesterday …”

Charles Darwin managed to write an entire book on evolution, that you might have heard of, entitled On the Origin of Species. I’ve read it a few times. Darwin made no references to philosophers, that I can recall. The book is one long disquisition on observed natural phenomena with some comparisons to artificial selection (i.e. plant breeding and animal husbandry). Does the lack of philosophical references make Darwin’s little oeuvre non-scientific, according to your standards? Just asking.

Since C02 adds not a single calorie of energy into the system, it can’t amplify anything. The only thing it can do is change the temperature gradient and/or effect amplitude and time constant of cyclical variations.

IOW, why is it not hotter in Atlanta, GA than in Phoenix, AZ (almost same latitude and altitude)? Just where are the effects of all the water vapor in the sky in Tahiti? It NEVER gets above about 33 C there. Why? Would someone please explain these FACTS, using all your understanding of IR, greenhouse gases, etc.

Re: Willis Eschenbach (Feb 13 12:27),
Willis, my point is as Phil Jones tried to explain, and you glided right past it to a facile soundbite. If you take a short period of time to compare trends, you will not get a statistically significant result, especially if the underlying error is large. The cooling trend from 1880-1890 would also have been not different, to a statistically significant level, from the trend any of those warming periods. That’s one reason why it’s generally recommended that you check trends over thirty years at least.
AGW predicted warming on the basis of the accumulation of CO2 and the radiative consequences. And it warmed. The warming is not the proof of the AGW effect, but it’s certainly consistent with it.

February 13, 2010 7:26 pm

Mr Eschenbach,
I’m curious why you didn’t address ocean warming, which is where most scientists believe the excess heat content is accumulating.
It’s important to point out gaps in the theory, but it gives a confusing impression when the area with the largest heat storage capacity on Earth – the oceans – are left out. I’d appreciate it if you could help me understand why you’re not looking at ocean temperatures.

February 13, 2010 7:28 pm

JAE
WHY is the temperature not higher in those areas with increased greenhouse gases?>
For the same reason that in a warming trend the arctic zones heat up much faster than the equatorial zones despite greenhouse gases like water vapour and ozone being pretty much absent. There are a lot of processes that move energy around the planet and it is the sum of those that result in a given temperature in a given place. Just as most of the greenhouse gas (water vapour) is at the equator, the heat trapped there raises the rate of convection which moves energy away from where it is being trapped. as a consequence temperature variability is muted at the equator where there’s lots of greenhouse gas, and accentuated at the poles where there’s not much. Over simplification but you get the idea.

Today Fox News had an interview with a skeptic about global warming and the weather. I only caught the tail end of the interview. She announced that President Obama has formed a cabinet level post, not authorized yet by Congress, to be Climate Guardians. The administration has dropped global warming as a concern and is now focused on climate change and pollution. They are citing the recent snow storms as evident that pollution (CO2) is causing major storms. Thus it doesn’t matter what the average global temperature is any more, any major weather disturbance is reason to control CO2 emission and install cap and trade. Thus, administration dos not need IPCC or CRU or NASA science to justify the control of carbon in the atmosphere. I am flabbergasted! They have thrown science under the bus! Have any of you heard about the new Climate watchdogs?

That article mentions Anthony Watts’s work on temperature stations and their problems. I’ve thought for years now that Anthony’s angle was promising and fresh, targeting some clay feet. There are folks who get their paperwork right and get taken in and, on the other hand, there are folks who are hands-on and find the devil in the details. Okay, that’s simplistic.

I like the way you summed up the whole “climate change” religion in the most concise and scathing manner:
In primitive tribes, when the volcano erupted, the shaman said the spirits were angry and must be appeased. Throw in a virgin. Every year that the volcano didn’t erupt was now proof that throwing in a virgin prevented eruptions. If the volcano DID erupt again, that was proof that they weren’t throwing in ENOUGH virgins, so go get more. The shaman wasn’t interested in determining the link, if any, between virgins and eruptions. He was interested in fitting the data to his theory so he could maintain his position as shaman.

No, you’re working with arbitrary intervals that someone made up. If you choose short intervals, you have less chance of getting a statistically significant result. It doesn’t disprove anything.

@ Ron Broberg (15:06:33) :
My, you like using bold. Hope you don’t mind if I skip it when quoting from your post.
AGW predicts warming.
It wasn’t invented to explain it.
Warming did not lead to AGW CO2 theories. CO2 warming theories were advanced in the 19th Century. (…)

*ahem*
From here:

Like many Victorian natural philosophers, John Tyndall was fascinated by a great variety of questions. While he was preparing an important treatise on “Heat as a Mode of Motion” he took time to consider geology. Tyndall had hands-on knowledge of the subject, for he was an ardent Alpinist (in 1861 he made the first ascent of the Weisshorn). Familiar with glaciers, he had been convinced by the evidence — hotly debated among scientists of his day — that tens of thousands of years ago, colossal layers of ice had covered all of northern Europe. How could climate possibly change so radically?

Did you catch it this time?
Tyndall thought there were massive layers of ice in the past, which now were gone. To him, this was evidence of warming, and drastic warming at that. From this came greenhouse theory, then AGW CO2 theories later.
Warming did lead to AGW CO2 theories.
GW CO2 theories (no “A”) were invented to explain warming. After expanding them to AGW CO2 theories by figuring in the additional CO2 contributions by humans, they were used to explain recent warming.
Any further arguing is over semantics. And will miss an essential point, that current AGW CO2 theories do a shoddy job of even attempting to account for natural reasons for recent warming, preferring to instead squarely blame man for the warming. And that is a travesty.

Re: Willis Eschenbach (Feb 13 23:46),
“Nobody “chose” the length of the intervals as you claim.”
Well, where did they come from. Nature doesn’t ring a bell at the end of a warming period. 2008 was cool, 2009 warmer. If 2010 is cooler again, is that the end of a warming period.? As Ron Broberg pointed out for warming since 1995, There’s only a 26% chance that you’d get that from random (natural?) variation. It’s not long enough to get 95% certainty, but it’s warming.
Jones carefully caveated his statement by
“Temperature data for the period 1860-1880 are more uncertain, because of sparser coverage, than for later periods in the 20th Century. The 1860-1880 period is also only 21 years in length.”
It didn’t come across well in the interview format, but he’s clearly explaining the issue re statistical significance. Then he says, carefully:
“So, in answer to the question, the warming rates for all 4 periods are similar and not statistically significantly different from each other.”
He could (and probably should) have simply said, “in answer to the question, no, they are not identical”. He’s trying to make the question make scientific sense. You’re turning it back into nonsense.

This is altogether too straightforward and inarguable. How are we going to provide employment for “thousands of scientists” who thought there was “overwhelming evidence” of human-induced global warming – when even Blind Freddie can see that there isn’t a job to be done?
For several centuries now, scientists always and everywhere have respected the principle of “Occam’s Razor” – which requires over-complex hypotheses to give way to simple and elegant explanations of the available data.
An explanation that “it must be wrong because my model can’t replicate it”, is undercut by the fact that the models can’t replicate the other two modern warming periods either. This argument has been met in the past by denying that the 1860-1880 and 1910-1940 warming rates were reasonably comparable with 1975-2009. Now the guru himself, Phil Jones, has stated unequivocally (on the BBC no less) that all three periods “are similar and not statistically significantly different”.
Game,set and match!

In response to my query to the Met Office about differences between station data and CRU data, they gave me the following statement. It seems the data cannot be relied on.
“It is inevitable that available archive versions for some stations will differ between data held by National Met Services, including the Met Office, and those in the archive prepared by the Climatic Research Unit at University of East Anglia. Indeed, explicit wording to this effect was required in the letters sent to gain permission to release data under the purview of each NMS. Most of these data recovery and digitisation efforts occurred in the days before widespread computer networks, designated world data centres etc. Therefore such vagaries as the choice of record version (there are often several paper records for the same station that may differ), choice of stored data accuracy, exact location details, and length of record digitised are
bound to differ for at least some stations. Further, either the NMS and/or CRU may have applied adjustments to the data. Differences between the archives cannot be used in any meaningful or quantifiably defensible sense to infer the absolute quality of either the CRU archive or records held by others. “

RE: Ron Broberg (12:07:02) : “AGW theory arises from (first) an understanding of the radiation properties of the CO2 atom and (second) the interactions of these physical properties in a broader climatic system. Warming is the prediction that results from AGW theory.”
The ‘W’ in AGW stands for warming so one cannot separate the ‘theory’ from the prediction. You seem to be confusing the ‘Greenhouse Effect’ with the [Catastrophic] Anthropogenic Global Warming ‘theory’ — more correctly ‘hypothesis’ or technical legend. I believe this technical legend is in fact based on a lack of public understanding CO2 absorption and its minor role as a greenhouse agent.
Recently, Science Magazine Online has reported a NOAA study indicating that stratospheric water vapor (SWV) concentrations decreased by about 10% after the year 2000. They say this has reduced the temperature increase from 2000 to 2009 by about 25% compared to that due to other greenhouse gases. They also say there is also some evidence that SWV increased between 1980 and 2000, which would have enhanced the warming during the 1990s by about 30% compared to estimates neglecting this effect.

I shall bow to Willis’ response to you, he being an actual scientist and me just a pretend scientist, but I find these scientists pursuing excess heat content in the ocean a bit amusing. Having attributed the properties of energy generation to CO2, and/or underestimating or ignoring negative feedbacks in their models, they are desperately trying to find a place where the energy they invented to warm the planet is going, since it isn’t warming the planet. The notion that perhaps the energy they invented never existed doesn’t seem to have crossed their minds, so the big gigantic ocean must be where its going.
The problem is the physics doesn’t work. Sunshine being short wave, it can penetrate the ocean up to as much as 300 meters. In brief, it could in theory heat up the top 300 meters of ocean. The long wave radiance re-radiated by CO2 and water vapour can only penetrate the top few millimeters of ocean. Heating up such a thin layer of water would certainly transfer SOME energy to the ocean, but MOST of what we are talking about would result in that thin top layer evaporating into the atmosphere, taking the heat with it.
So if some scientist finds a gigantic heat reservoir in the ocean that is coming out now or in the future, I can understand how past fluctuations in solar energy might have built that. Longwave radiation… not so much.

February 14, 2010 8:00 am

Hi you all!
I have noticed that a hot debate is still the issue on whether or not CO2 has anything to do with global warming. Personally I donot believe anymore in global warming as such because it cannot happen. Earth has its own cooling plant with a built-in thermostat.
But before I realised that, I looked at the carbon dioxide issue, mostly because of Al Gore’s movie (made me feel guilty about driving a car)
I will agree with the warmists that CO2 traps heat (from earthshine 24hours per day) because of the absorption of CO2 in the 14-15um wavelength. I say, good, fine I believe you. But likewise there must be cooling because of various absorptions of CO2 in the range from 0-5 um (from sunshine 12 hours per day)! This cooling must logically take place everywhere where there is CO2 and where sunlight hits on the molecule regardless of height or pressure.. It is even so apparent that this happens that this radiation can be measured as it reflects back from the moon. So my question was and is: exactly how much cooling and how much warming is caused by the carbon dioxide?
So far no one has been able to show me the balance sheet i.e. exactly how much cooling and how much heating is caused by CO2. My point is that we (scientists) really have not established if CO2 really does cause warming. They did tests with 100% CO2 but that is the wrong kind of science. You have to prove your theory in the proper range i.e. 200-500 ppm. Every scientist knows that properties differ at various concentrations of solutions.
It appears that I cannot find this research because it seems to me that such a simple observation of mine (ie. that CO2 also must cause cooling) has never been taken into account. Where the IPCC got its values from (for “forcings”) is a mystery to me but it appears not to be based on actual measurements (research) that would produce a formula of some sorts. I think they were all just weighted values.
(e.g. “global warming” related to the conc. of CO2 since 1750 AD. Theory: Let us have planet, add some carbon dioxde, see if the temp. went up , it did, so that must be it. But that is working at a solution to the problem, if you are 100% sure what the cause of the problem is. Nevermind Willis’ theory here that we donot really have a problem – which I agree with)
Like Willis said earlier, all I could find is computer models. Svante Arrhenius formula does not work. If his observations had been correct, earth should have been a lot warmer by now.
So what I donot understand is: why don’t one of these so-called warmists (Leonardo di Caprio?) sue the gas companies (for causing global warming) instead of trying to convince us that it is our problem. Then you must see how quickly the gas companies will find the money to carry our the proper research to prove that it is not the carbon dioxide….
To me, the whole CO2 science is an unbelievable scam, the hottest hoax of this century. Obviously there must be big interest groups, those that are bigger than the gas companies, (even our pension funds!) that want this scam to continue.

Richard Telford, your claims on behalf of Ralph F. Keeling are at odds with his own published work. Here is a rather a nice non-copywriten paper that covers the fiendishly difficult background to measuring the steady state levels of atmospheric gasses. Note also how he is very modest with his claims, knowing that the system he is viewing is very complex. In this paper he is measuring changes in Ar/N2. Note that N2 concentrations are biotic, but Ar is not. Keeling is doing very nice science, and points out the problems associated with measurement.
I urge you to read it before trying to state that the fall in O2 levels is due to CO2 generation.

“Developed by prominent atmospheric physicist Dr. Ferenc Miskolczi, the new theory is enormously significant because it demolishes the prevailing doctrine of anthropogenic greenhouse warming (AGW), which blames humans for pumping CO2 into the atmosphere and triggering runaway global warming that could eventually lead to catastrophic climate change.”

It’s time to halt Cap and Trade and all other forms of Carbon Taxation until the scientific community have produced a truthful and transparent appraisal of what, if anything, is happening. I am a Heating Engineer and Energy Assessor – my whole objective is to conserve a our natural resources until viable, economical alternatives can be found, and to saving businesses money. I know (being an expert!) that you can only get a pint of milk out of a pint bottle and it eventually becomes empty – that I believe of oil and gas.
The businesses are struggling, especially in this economic climate. I get many enquiries (corporate to small private) where the solutions to them meeting their targets are beyond their financial means- even with grants (which are false economy anyway). At present they know they will be penalised by the carbon tax regulations, but they are not able to do much about it. The EPBD 2006 (Energy Performance in Buildings Directive), is at the moment being reviewed by the European Parliament and more than likely extended with even more regulations, policies and policing to enforce the regulations. If it turns out that most of the data is inaccurate and corrupt, then this will go down as the biggest Political and Corporate scam and theft of all time – billions absolutely and totally wasted. That money could have been invested in alternative technology, which would have solved their problem anyway – even if warming did turn out to be true. Unfortunately it looks as though the Chinese and Indians have beaten us to it
with their alternative energy technology.( they have no global warming policy to worry about).
Its now time to bottom it all out, cut out the bad once and for all and move forward. If these recent revelations turn out to be true, in a way, we only have ourselves to blame for not being more vigilant – there must have been enough doubters, scientists and politicians out there over the last forty years to question the events that have led us to this situation?

There’s some easily accessed data that doesn’t make a conclusive point, but should make anyone on the CO2 bandwagon pause and go huh? Over here http://www.esrl.noaa.gov/gmd/ccgg/trends/ you can see a plot at 3400 meters of the CO2 concentration in the atmoshpere (this is the one IPCC et all keep referring to). You can easily see that CO2 concentrations peak about july/august each year.
Now zip over to the AMSU-A site where you can see their satellite temperature data. You will need java installed on your browser. Click on the “global atmospheric trend” link and you can look at any channel or year that you want on the graph. Unfortunately they don’t have a channel at 3400 meters, but they do have one at 4400 meters which is reasonably close. Every year peak around July/August. Then turn on the “near surface” channel. Every year, peak around July/August. Now turn on the Sea Surface channel. Oops, where did the July/August peak go? The peak moved to more like february/march and actually has a depression in July/August.
So… what ever energy transfers are taking place between atmosphere and near surface seem linked, though which drives which is a different question, the oceans merrily wander around responding to input variations from the sun and angle of the earth’s axis to it (which would maximize energy input in feb/mar due to preponderance of ocean in southern hemisphere) and pretty much ignoring any long wave energy transfers from the atmosphere.
Which would fit exactly with the physics….

Rob (13:13:29), nice video. It supports what EM Smith as been saying for quite awhile. The warming that we have seen is at night and at higher latitudes. Note you don’t see the warmers addressing this because it cuts the legs out of any argument that AGW will lead to major problems.
The real impact of the recent measured warming (if you accept it as true) is longer growing seasons, more arable land and higher crop yields. Not exactly a catastrophe.

An interesting technical paper. But a little further digging on at Keeling’s group’s site would have uncovered several papers describing how they interpret their results on oxygen concentration. For example Langenfelds et al 1999 Partitioning of the global fossil CO2 sink using a 19-year trend in atmospheric O2, Geophysical Research Letters, 26, 1897-1900. http://bluemoon.ucsd.edu/publications/ralph/25_Partition.pdf
There are numerous other paper by this group linking a decline in oxygen concentration with fossil fuel combustion. I don’t know why you find this so contentious: burning carbon consumes oxygen. With sufficiently precise instrumentation, like that Keeling has produced, this can be detected and used to help partition the CO2 sink into its various components.

Willis Eschenbach appears to have convinced some people that there is nothing even “slightly abnormal” about temperatures in “Merrie Olde England”, which have only been increasing slowly.
Of course, if you plot the temperatures on a graph with a range of 40deg.C, as Willis does, then you can guarantee not to show much of any warming that has occurred. You could call it, “hiding the increase”.
But, if you want to see how things have actually changed, then use a graph with an appropriate scale on the y-axis. Like this one, for example, which shows the ten-year average CET temperature anomaly since the seventeenth century:

Yes, you are quite right, the merrie Olde england graph has a range of 35deg.C, not 40.
I’m sure I remember noting that it was 35C – I must be getting glaikit … .
But otherwise I find nothing of merit in your post. The graph I linked to shows the ten year average of the Central England Temperatures series and clearly shows the warming that Willis Eschenbach goes to great lengths to hide. What does it matter what the source of the graph is?
Although I rate Tamino’s abilities and clarity of thought very highly, (and the “Summer and Smoke” February 15, 2010 article to which you refer, here:
http://tamino.wordpress.com/2010/02/15/summer-and-smoke/#more-2279
is a must read for WUWT followers) … the “too simplified graph” to which you refer can be replicated by anyone with a little skill with Excel, so its origin is irrelevant.
But in what way is it “too simple”? It contains all the data from the CET series with the temperature values averaged over ten year periods. That has the advantage of largely smoothing out the influence of such things as El Nino/La Nina episodes or volcanic eruptions and all the other events that cause short-term changes to the temperature series. By “simplifying” the graph this irrelevant noise is largely removed and the underlying changes made more obvious. There are of course more sophisticated methods of smoothing graphs, but it seems to me that the great advantage of ten (or five or whatever) year averages is that most people can replicate them themselves: they can take the raw data and see from their own efforts that what people like Tamino are saying is true.
Tamino’s graph has a range of a couple of degrees or so: entirely appropriate since that is the range of temperature variation involved.
You tell me why it is appropriate to draw a graph with a range of 35C for England or 30C for Armagh unless your purpose is to obscure the warming that has occurred.

Barry Brill
February 16, 2010 3:38 am

Kadaka – the origin matters, because the graph or its underlying data might well have been tweaked, or corrected, or adjusted, or homogenised.
We know from Prof Phil Jones that the current warming was matched by earlier global warmings in 1860-80 and 1910-40. Is it just bad luck that CET (as per your graphical version) missed out on both of these previous events?

I think your post was addressed to me rather than Kadaka. You state, “the origin matters, because the graph or its underlying data might well have been tweaked, or corrected, or adjusted, or homogenised.”
Then go to the source of the information here:
http://hadobs.metoffice.com/hadcet/ssn_HadCET_mean.txt
Paste this into Excel. Go to Data (in Excel 2007 if you have it) click on Text to Columns and just follow through the wizard so that you get the five columns of data (year, spring , summer, autumn, winter) in five separate columns. Average the seasonal data in another column to the right to give you annual means, then again average those annual means into ten year means. Plot a graph of the results. (You get a better graph if you subtract 9 from the ten year average temperatures, so that the range is from c. -1.5 to +1.5 .) It is just the same as the one Tamino provided (though not as pretty, at least not with my limited IT skills).
It is just ridiculous to go on year after year being misled by graphs like that provided by Willis Eschenbach when the raw data is there for the picking and anyone with a computer and the most basic skills can see for themselves what the data actually shows.
Tamino’s (and my) graph does show the 1910 to 1940 warming (though the ten year averages are centred on 1915, 25, 35 etc. so it is slightly different) and also ac. 20 year rise around 1860.

Why is something a “must read” that starts off talking about “D’Aleo and Watts’s denialist document”? What benefit is derived from reading such overtly biased drivel that one must experience it? What is next? Will you recommend I study anti-Semitic hate speech to understand the politics in Israel?

But in what way is it “too simple”? It contains all the data from the CET series with the temperature values averaged over ten year periods.

Nah. As you stated in Slioch (07:04:26), the seasonal data was used, not the monthly as Mr. Eschenbach used. There is no trend line, no rate. It uses anomalies instead of real temperature values. As opposed to using a baseline range of years to compute anomalies as we are used to seeing, it looks like the graph was simply centered. Heck, it doesn’t even mention what the red dashed lines are. Too simple.

You tell me why it is appropriate to draw a graph with a range of 35C for England or 30C for Armagh unless your purpose is to obscure the warming that has occurred.

For the CET data, my attempt at graphing it with 5-degree major intervals also resulted in a +25 top line. The maximum value in the data is 19.7, apparently the software (Open Office for me) likes to have enough margin for a nice display so +25 it is. In the above graph, the 25-yr trailing trend data clearly dips below -5, so -10 gets chosen for the bottom line. Nothing nefarious there, the 35 deg range is simply how the graph turned out. For the Armagh graph, I can clearly see data above +15 and below -5, so +20 and -10 lines are generated, a 30 deg spread. For the CET graph, you could argue the top line should have been forced to +20, but that gets rid of the nice space where the trend info is.
Besides, what you seem to fail to realize, you are really complaining not about the range but about the aspect ratio. If the Y-axis was longer with the same range then you could more clearly see whatever-it-is you are going on about. If you are going to try to successfully complain about something, at least complain about the right thing.

Hi Guys
Interesting discussion and debate – and I have to admit I have not followed all the details. However I do know that a lot of data is corrupted by the energy consumption in the vicinity of tempereature measureing stations. One can look at http://fitzgallery2.youthsite.net/main.php?g2_itemId=2575 to get some idea about concentrations of energy consumption (and yes before someone critisises me for the bleeding obvious, I realise this is a manufactured image because you’d never get clear skies over anything like this area at the same time).
Wherever there is an energy usage concentration temperature measurements are affected. In my state of Victoria in Australia, the CBD of Melbourne with a population approaching 4 M has a temperature profile that may be up to 2 degrees C higher than the surrounding area around the city (just checked at the moment and its plus 1.4-1.8 degrees C).
Hence would suggest that unless someone has long term temperature data from a wide range of locations where energy consumption is low (this would exclude data from any significant urban area, and arguably exclude all data from the Eastern half of the USA), has a good knowledge of natural phenomena that impact on temperatures generally (for example the irregular movement of weather patterns towards or way from the equator that may dramatically alter rainfall patterns from time to time and hence surface temperatures, or el nino and other oscillations) and really good data analysis skills, then we can never prove anything in respect of climate change.
However it is a simple matter to look at the data and come to a view that first world countries are consuming energy at an unsustainable rate. And then have the determination to influence governments and others to do something about that waste.
Saves an awful lot of arguments!

@ John Lambert (05:04:32)
Why do you think first world countries’ energy consumption rates are unsustainable? Do you have any evidence of that? You dont think mankind will be able to figure out ways to use even more energy in the future in sustainable ways, as he always has? Why the doom and gloom?
We once were thought to be running out of whale oil for lamps, and wood for fires and building, and you name it…but we didnt. We still have all those, and every other natural resource we ever used. We never ran out of a single one. Can you think of one we ran out of? We just found other sources and better technologies. Incidentally, we have enough plutonium to power all our electric needs for the next several thousand years. I bet we come up with heretofor undreamed of better things than that in that time. If we even need to.

John Lambert
February 21, 2010 1:39 pm

@ Bubba
I have a simple view based on the ideal of the whole world having a smilar lifestyle. To achieve this goal would require annual energy consumption world wide to increase by 4 times. If the increase was to be supplied by oil and gas alone then production would need to increase 7 times – and there would be huge cost increases based on market demand. If the increase was to be supplied by coal alone then production would need to increase 15 times – and there would be huge cost increases. If the increase was to be supplied by nuclear alone then production would need to increase 70 times – and there is huge resistance to expanding nuclear energy electricity production in first world countries, and huge resiatance from first world countries to allowing many less advanced countries to go down the nuclear path because of fears of terrorism or nuclear weapons production (note if every nuclear power plant that has been proposed to date was built it would only double nuclear output.
Not only would you and I be paying several times the cost of current power, but the costs of all the things we purchase would go up dramatically because the cost of energy to produce them would go up, and the items sources from China, India, Korea and other low energy consumption countries would increase by 10 – 100 times because both energy costs and labour costs would increase dramatically.
The end result necessarily would be a significant lowering of the standard of living we enjoy.
That’s why the energy usage rate of first world countries like USA, Canada, the original EU countries, New Zealand and Australia is unsustainable.

Bubba
February 21, 2010 5:19 pm

John Lambert (13:39:25)
Aaah. So there is “huge resistance” to nuclear power in the first world. (Except for France, of course which gets almost 90% of its electricity from nuclear.)
So what you are saying is that the energy “problem” is political, rather than any real issue with natural resources or pollution or supply and demand. In other words, we have the means, the experience, the smarts, and the financing to sustain many times our energy usage right now, but certain people simply refuse to allow this to happen. Very well. That seems the most easy “problem” to fix, since no one I know is willing to give up their rising standard of living for a tiny minority’s political well-being, or some environmentalist’s irrational religion.
So we really have no need to pay “several times the cost of current power.” Nor do we have any reason for “the cost of all the things we purchase to go up dramatically” because of any energy reason either. We have oil and gas and coal to last for many decades at our current expanding usage rates, which is plenty enough time to convert to nuclear. We know how to contain the pollution those emit, and we know there is no CO2 causing any unprecedented or disastrous warming either. No need to lower anyone’s standard of living whatsoever. No need for any cost of items from China and India to go up “100 times” for any energy cost reason.
The increasing energy demands of the entire planet are are completely sustainable for thousands of years after all! Another crisis averted! Glory be!! We have the technology. We have the means. But do we have the political will to fight off the Gore’s and the Phil Jones’ of the world to keep mankind prospering?? We have indeed solved the argument as you have desired. That was pretty simple. End the elitist aims of socialism and government control over free people, thereby ending the energy crisis. Here’s to the very bright future ahead! Cheers.

Happy to oblige. Will leave your discussion reiterating my comments that until someone puts together a data set that enables “climate change” to be identified separately from the localised effects of high energy consumption raising temperatures at weather stations in cities and high energy consumption areas there will never be a proof either way

March 7, 2010 8:25 am

Thanks Willis for all these updates. That really gives us a better picture. It proves that the zero hypothesis must be considered true: there is no global warming.
From this, my new hypothesis is this:
Carbondioxide (CO2) is good for life. My theory is that as CO2 rises this is good as it would lead to better crops (acting sort of like fertilizer) and would stimulate forest growth. To ask for a reduction in CO2 may be just as non-sensical as to ask for a reduction in water vapor.

Hi Willis
Read “Quantifying the influence of anthropogenic surface processes and inhomogeneities on gridded global climate data” by Ross R. McKitrick, and emailed him congratulating on his effort. The fact that at the broad level of analysis he used, the global “temperature increase” of 0.4 degrees C was halved is of great significance. I went on to point out the extreme difficulty in actually proving temperature change even at an individual site. And I used Australia’s two largest cities as examples.
Sydney CBD temperatures are moderated by the ocean along Sydney’s East and the harbour it surrounds. As a result maximum temperatures are generally much higher in the western areas of Sydney. And hence determining any urban energy consumption driven heating effect on the Sydney CBD is challenging.
Melbourne in contrast does not have an ocean influence. However it is well recognised that on average air temperatures reduce by 1 degree C per 150 metres increase in altitude. And Melbourne is at 33 m elevation and effectively within a basin with 40% of the 73 weather stations within 110 km being at altitudes 75 metres or more higher (~ 0.5 degree C difference). Just determining the altitude effect at each site is a challenge.
The global air temperature anomaly graph infers that ideally 150 years of continuous data is available, though it may be possible to use as few as 70 years. And the last 30 years are critical. The Melbourne site has 155 years of continuous data up to 2010. There is one site with 102 years of continuous data but it is at an altitude of 435 metres; a second site has 66 years of continuous data – however the spread of the Melbourne urban area means it has been part of the urban area for 25 years; and another site has 51 years of continuous data – but it is on the other side of the Dividing Range. Three other sites have 86 – 108 years of data, but the weather stations have been closed for at least 10 years.
AS a result just to analyse, calibrate and adjust Melbourne’s temperatures for the urban heating effect – it appears to lead to maximum temperatures around 1.5 degrees C higher than surrounding non-urban areas – would be very challenging and probably require weeks of detailed analysis.
And to do sufficient sites to accurately determine any global air temperature change could take 100’s of man years of work.

Willis,
Fig. 7, your text:
“The Alaskan temperature is regulated by the Pacific Decadal Oscillation ( PDO). The PDO shifted from the cool phase to the warm phase around 1986, and has recently switched back to the cool phase. As you can see, other than the step changes due to the PDO, there is little variation in the Alaska temperatures”
I think the PDO shift from cool to warm phase was around 1976, not 1986. Matches the shift in temperature better as well…
