Dr. Patrick Moore, who was one of the original founders of Greenpeace who left the organization in disgust of their current political zealotry, and Greenpeace is now trying to have him erased from history for daring to do that. He has now produced this interesting video in conjunction with with Prager University that is sure to put some people into conniption fits.
Global Warming activists will tell you that CO2 is bad and dangerous. The EPA has even classified it as a pollutant. But is it? Patrick Moore provides some surprising facts about the benefits of CO2 that you won’t hear in the current debate.

[thanks, fixed -mod]
Nice to see he is still around, in spite of the attempts to “disappear” him.
(Making inconvenient people disappear is standard practice. Thomas Paine was “disappeared” from the popularised, Disneyfied, versions of United States history for quite a while, even though he practically invented the country. I don’t know whether this was because of his opposition to Christianity, the socialist flavour of his writings on social justice, or the critical open letter to GeorgeWashington.
But they never airbrushed him out of the group photos of the founding fathers.)
The sentence so nice he wrote it twice…
A brilliant presentation – succinct and clear. Too bad he will never get air play on the mainstream media which seemingly backs the CAGW hoax.
Mod check paragraph 2. I am experiencing deja vu.
I think you mean deja view.
No, deja vu is correct, unless my French is horribly forgotten.
That was a joke.
I’ve heard it pronounced ‘Deja view’ so many times you just never know! Subtle humor is hard to discern sometimes. I’ll just sit here in my chaise ‘lounge’ and have another glass of brie.
Another “glass of brie”?? I hope that you don’t choke.
Good one, Dr. Patrick. We need more of these. Maybe one to show that the % of CO2 in the atmosphere is not ~25% as a lot of people believe. Video is simple and concise, with good graphics.
Now to get it into the MSM – lol (lots of luck) with that. I will share on my Facebook.
It’s worse than believing in 25% CO2 today: If one asks High School beginner classes in science courses to guess which gas is with nearly 80 % most abundant in the air, the majority of students will say CO2 instead of Nitrogen. If they hear the truth (only about 0,04% CO2) many of them look quite astonished. This reveals rather shockingly the intensive and successful CAGW brain washing of those kids in kindergarten and primary school today.
Yes, but at least they know how to recycle polar bears!
But, as Patrick Moore explains in the video, without that 0.04% the earth would be a dead planet. It’s about time we stopped this nonsense about CO2 only being a small proportion of the atmosphere so it can’t have any effect. It can and does. It’s clear from spectra viewed from space that CO2 is highly relevant with respect to absorption of LWIR.
Mr. Finn,
Who said it cannot have any effect?
Some say that whatever effect it has is minimal, some say warming is not a bad thing, and there seems to be a lively debate regarding whether the atmosphere cools or warms the surface, whether CO2 backradiation can possibly warm the ocean, and other such details.
But no one says that CO2 does not absorb and emit certain bands of infrared.
How about we stop the nonsense that unless we return the Earth to the conditions that prevailed during the little ice age, the oceans will boil, and we are all going to die of heat…right before we drown.
Or how about we get everyone to cut out the BS malarkey about how if the frozen wastelands at the to and bottom of the world get any warmer, humans cannot survive on what will be a cinder of a planet? How about that?
Or how about we just cut out all the alarmist warmista jackassery altogether, and call it a day?
I am good with that option, too.
How about we spend the $29 billion per year that is spent studying a settled science on studying real problems, or solving real emergencies? Instead of making up a fake boogeyman, blaming every conceivable problem on the Earth on that boogeyman, and accusing anyone who hates lies of not caring about the planet?
@John Finn
To made my point of view clear:
1) I stated here on wuwt quite often: CO2 is the GAS OF LIFE ! Thus I claim it’s very important indeed, but I think there is rather to little than to much in the atmosphere now, given that only 20 ka before our century plant life nearly perished with only 180 ppm.
2) I think, CO2 has some warming effect due to its LWIR absorption properties but believe that its climate sensitivity is only somewhere between 0.5 – 1.5 degrees because the feedbacks are likely more negative than positive. (BTW: With strong positive feedbacks, we wouldn’t be here today… 😉
3) I’m rather sure, that the mild warming which we can expect from rising CO2 by fossil fuel burning will be a benefit for Earth and Life. The real danger for mankind would be the return of a little ice age, or even worse, a full blown ice age.
But when many school kids believe today that CO2 is the most abundant gas in atmosphere, we see that the endless “CO2 is a dangerous pollutant which will destroy the planet soon – scare mongering” – has crossed the border of usual stupidity long ago…
John Finn
No-one said the 0.04% CO2 has no effect. It does. The “effect” is called life.
I still am wondering why the NASA OCO-2 team and associated researchers haven’t released any more global data pictures.
The only full presentation publicly released so far was the initial one last December:
http://www.nasa.gov/sites/default/files/styles/full_width/public/mainco2mappia18934.jpg
Are they seeing things that refute/weakens the Climate Change dogma of a manmade GHGs? Which if they existed of course must not be allowed to see the light of day, especially heading into Paris COP15. This complete lack of trust in NASA’s and NOAA’s integrity on climate change issues is their own doing. The damage to their reputation will be severe when the extent of their temp data manipulations is fully exposed. Does it now extend to CO2 data?
They are still “adjusting” the data.
Soon you will see the “true” version. /sarc
It now appears (as I predicted last year) that the purpose of OCO-2 was to pave the way for OCO-3, 4, 5, an on-going forever program, it is really all about JPL/NASA future funding. OCO-2 does in fact have the capability, if all the pure raw data were made available, to seriously damage the anthropogenic apocalypse hypothesis…
vonborks,
While OCO-2 data collection needs to continue for decades so that we may better understand the carbon cycle on Earth over longer periods, is disagree with your OCO-2 premise that this a just a “self-licking ice cream cone”. The Climate modelers are an example of models for modeller’s sake with no scientific value (political value for sure though), i.e they are “self-licking ice cream cones”.
As an erratta to my top-level comment, it should read “COP21” not 15.
Good question. The map shows most of the CO2 emissions to be in the Southern Hemisphere where there are far fewer people, cars, and less fossil fuel burning, apart from a blob over NE China, than in the Northern Hemisphere, yet most of the warming seems to be in the Northern Hemisphere—0.7dC(NH) vs 0.38dC(SH).
Maybe CO2, mankind, vehicles and fossil fuel consumption are not The Cause…
Or, the data—ah, satellite— is obviously wrong.
Probably due to termites. They produce an awful lot of CO2. Electronic termite detectors actually measure CO2.
Could it be due to the time of year of the data collection, i.e. fall in the Northern Hemi. and spring in the Southern Hemi. ??? Just a thought that may be wrong.
Uhhh , just ask them and watch what happens
gsfc-help-disc@lists.nasa.gov.
The data is all there. go and check it out.
Go get level 0 data which is raw bits.
here is a simple description
http://disc.sci.gsfc.nasa.gov/OCO-2/documentation/oco-2-v6/SDOS_SIS_L1aIn.V6.pdf
What kind of computer hack wrote this document? Hopefully not another English major.
“The following set of tools can be used to open and examine this HDF-5 product on Linux systems”
Really what “Linux” system? Forget versions, can it be processed on the over 800 Linux distros know to have existed?

What a joke that our tax money goes to pay for this nonsense.
They’re busy posting trash like this to their twitter feed. https://twitter.com/iamoco2
“If you didn’t see it before… Climate deniers blame global warming on nature. This NASA data begs to differ http://www.bloomberg.com/graphics/2015-whats-warming-the-world/ …”
The Roston-Migliozzi data graph at that Bloomberg presentation was thoroughly debunked and (shown as…fake modelling) falsified in multiple threads here at WUWT. Several here:
– http://wattsupwiththat.com/2015/06/30/bloombergs-alarming-graph-are-we-really-on-track-for-4c-global-warming-by-2100/
And the best debunk of that Bloomberg trash:
– http://wattsupwiththat.com/2015/06/27/bloombergs-made-up-climate-widget/
There is no vertical scale presented for the graphs in the examples presented in the Bloomberg article display.
The thing that CAGW proponents fail to explain is the slope of the GISS land ocean temperature graph from circa 1910 to 1940 and the leveling off from 1940 to 1970 and the almost duplicate increase (1910-1940) from 1970 to 2000. As I understand the data, CO2 did not increase very much before about the 1950’s. So, what caused the run up from 1910 to 1940, if it wasn’t natural causes. The models mentioned do not predict the GISS temperature graph. What gives?
The other problem with the presented data is that it doesn’t take into account the urban heat island effects on the temperature record, or the effects that cosmic rays vs. sun’s magnetic field has on the cloud formation/cooling of the earth, which may prove to be a very big natural cause. The ocean temperature oscillations/phases are not mentioned except for a brief reference to El Ninos, with no plot dedicated to them or their effect.
So, if I understand your position, I think you and GISS may need to go back to the drawing board, until you understand and can explain ALL the natural factors, which factor into the complex system known as the Earth’s climate.
If the model results do not predict reality, they are wrong. It is just that simple.
Sorry, I didn’t see Mr. O’Bryan’s reply before I posted.
There’s a 226Gb download of the raw data available here if you want to analyse it yourself.
Thank you. Less than 5 minutes to explain why CO2 is life-giving… without it we are all dead. Simples.
When will the so-called climate scientists just shut up and do some honest science?
Should we use word “organic” to mean carbon in our talks. Organic chemistry is carbon based chemistry though basic C and CO2 are considered inorganic. Hydrocarbons are surely organic. So oil is an organic fuel.
Methane and other carbohydrates are found from other planets in our solar systems though fossils are not. So, let’s talk about organic fuels instead of fossil fuels. Carbon pollution is then organic pollution if someone wants to use that meme.
I want to use that meme and I will. It should be pretty handy to confuse Progs who are proud of “going organic”.
Dichloromethane as salad dressing, to go with that organic salad
Mick, I got a chuckle out of your comment, but you don’t need a synthetic molecule to make the point. Botulism, conotoxins, cholera, and typhoid fever are all “natural” and “organic”.
Couple of nitpicks on the video.
– Plankton was mentioned as a CO2 consumer, but a krill was shown in grphic cartoon. Krill are on the next step up in the ocean food chain from plankton.
– The Cambrian Explosion was not the birth of multicellular organisms. The Cambrian explosion was a rapid diversification and radial expansion of many different types of body type organization patterns in complex life form development.
The use of an animal to illustrate phyto-plankton rasped at me a bit as well.
Sorry, graphics folks not plankton morphology experts. Technically the Cambrian was birth of tissue differentiation. Multicellular life before that was just chains of identical cells. Cambrian was fundamental to modern life species.
The important thing that no one mentions, specially those who sell cars, is that from the burning of fossil fuels, out of exhaust tubes, comes out a whole lot more than just CO2.
In fact, CO2 should be the least of our worries compared with the other emissions, like oils and heavy metals.
Don’t like CO2? Good, do us all a favor and kill yourself, just by living you are, at least (if sedentary), exhaling 1 Kg daily.
La Pirula Roja
Hmmmmn. Have you sterilized yourself, your family, your parents and all of your brothers and sisters yet? Are YOU living in a mud hut in central Africa with no power, lights, heat, air conditioning, and no internet access for your rock tools and wood-and-dung fire?
(Oh. Wait. You DO have internet access. Must be one of those powered by a lodestone twirled inside a copper bowl you mined with a pickax made with a stone-tip and wood-handled shafts tied by a hand-dried leather strap you harvested by killing an innocent animal.
Remember however, that modern cars exhaust significantly less nasties than older cars did. You can’t even kill yourself by running the tail pipe emissions in through your window anymore. Not enough CO…
Cars aren’t the villains they used to be in the 70s…
“Not enough CO”
I wouldn’t count on it unless there’s been a dramatic, reliable improvement in fuel combustion technology in the past 20 years. Maybe there has been such an improvement, but I still wouldn’t trust having an idling car in my closed garage.
Hemoglobin gathers CO at ~200 x the rate it takes up O2 – they compete for the same site on the hemoglobin molecule – so you don’t need a very high ambient concentration of CO for it to be toxic – 0.1% CO gives you a usually lethal result, because it effectively reduces your Oxygen supply to 50% of normal, when pO2 in your blood would be ~27 vs normal of >90 [the relationship of pO2 to what hemoglobin can carry is not linear, so at pO2=27 hemoglobin still is 50% saturated with O2 but that’s usually not enough – I did see on guy with that level who lived!]
I understand how carbon monoxide toxicity works. I didn’t say it’s healthy or advisable to hook up your snorkel to the tailpipe. But your caveat is true: emissions profiles are very different now. It’s not a sure thing anymore, and suicidal people are turning to other means of CO procurement. Faulty old gas heaters are an accidental source. Grilling in a garage when it rains (yes, really)… the usual…
“You can’t even kill yourself by running the tail pipe emissions in through your window anymore”
Hmmm, don’t let the eco nutters in on this gem, they will repeal all tailpipe emissions laws just to get the suicide count up to meet their agenda 21 targets.
I knew someone who offed themselves a couple of years ago and the car was almost new.
Nutty Professor, who reads this list, surveyed poor township shack populations for CO exposure from burning coke indoors in buckets. He found homes with CO levels of 1600 ppm (0.16%) and people living like that.
It shows that the body can learn to tolerate much more CO than is sometimes expected. I can’t recommend it, but this is the reality.
In a garage with a running car the CO2 will kill you very quickly s well. We exhale CO at a rate of about 1.6% of our rate of CO2 exhalation. In a crowded room or overturned Posidon the CO2 level goes up 60 times faster than the CO.
huh?
Yeah, I highly recommend that no one test this idea that modern cars will not kill a person if the exhaust is vented into a closed space.
Ok, I guess I have to spell things out completely or risk rampant malicious point-missing. It is not healthy or smart to vent your tailpipe into your closed up car. The displacement of oxygen alone, in an ideally sealed space, would eventually be deadly.
Car emissions, thanks to catalytic converters and endless other improvements, are far cleaner than they were in the time in which car-haters seem stuck. And the once-reliable method of suicide is no longer reliable, because the level of CO in emissions has dropped dramatically.
Hating cars doesn’t save the planet. Driving cars doesn’t destroy the planet.
It’s the carbon monoxide that kills you when you suck the tail pipe no? still just as effective as ever.
No, Michael, it isn’t. In my profession, I occasionally respond to car-exhaust suicides. Late model car? Dead. Newer car? Choking and coughing, snotty, blood-shot eyes, but alive. Not always, of course. But before, it was never. Do you see the distinction?
“just by living you are, at least (if sedentary), exhaling 1 Kg daily”
I tried calculating that figure for the average CO2 exhalation of an average person on earth per day – making many wild “sounds about right” guesses about what an average person was and what they were doing – and got exactly 1 Kg! I’ve read that the Gov’t quotes 900 gm./day, but have never found how it or anyone else calculated it. Maybe it was measured?
I also calculated that a heavily exercising person could produce about 1 pound = 454 gm. of CO2/hr.
JPeden –
found this o be a pretty good reference:
http://www.normalbreathing.com/CO2.php
I read somewhere that body fat is turned into oxygen and CO2 by an excersising body, it was some huge amount of exhaled CO2 per Kg of body fat, at the moment obese people are sequestering a lot of CO2, greenies will be targeting joggers and gyms next with a polution tax, hey perhaps we can get a rebate if we are overweight, bring on those big mac’s i have to do my part in saving the world.
“Bubba Cow July 28, 2015 at 3:41 pm”
Thanks, it looks interesting and gives CO2 a good name vs CO2-Climate Science!
Yes, what has become of NASA’s OCO-2 data?
As neophyte this was the first thing that struck me 5 or 6 years ago when the Carbon Exchanges were first set up. How could something so wonderful be so bad.
My climate skepticism was prodded into existence back in the mid 90s by just this point. CO2 fertilization is so obviously definitely a benefit, yet there was no mention of that fact by the official organs of our public culture.
The real turning point for me, was that after many years of waiting for some acknowledgement of the benefits of CO2 as a plant fertilizer, I finally did see such a story. What was the context? Poison Ivy! Because of increased CO2 Poison Ivy is going to grow faster! Bad, bad, we should therefore all be climate alarmists.
At that point you’ve got to see. The main stream media and government sponsored science have little interest in being objective. They begin their thinking with alarmist conclusions, and the data is folded, spindled and mutilated to fit the narrative.
I saw that too! Summer of ’07 in a Toronto paper. I asked my girl why not ALL plant life, she scratched her head…
When CO2 increases in the atmosphere the earth heats up. Even this dude doesn’t dispute that. He says CO2 is put into greenhouses to warm them and boost growth (during cool climates I might add). This is why it is called the greenhouse gas effect. The CO2 being released from the accurately named fossil fuels have been stored over billions of years from a time when oxygen concentrations in the atmosphere were too low to support human life. Oxygen concentration is currently decreasing in the atmosphere as the result of green house gas emission. CO2 is important to plant growth, but not to human growth. He has very carefully avoided all points that contradict his misguided speech. Climate change is very real. There is just no motivation for a climate change conspiracy. It’s a stupid idea.
Adam
Care to calculate that lie – that exaggeration – you are promoting?
No Problem:
O2 – 21% of atmosphere
CO2 – 20 ppm anthropogenic contribution, depleted O2 1:1 mole to mole
21% – 20ppm = 21.0 – 0.00002 = 20.99998% O2
OMG – We are all going to suffocate! It’s Worse Than We Thought (TM)
CO2 would not displace just O2, but also N2, Ar and trace gases. In fact, since O2 and Ar are more massive than N2, nitrogen should be the molecule most shoved around by the beefy CO2 intruder. Not to mention wimpy H2O.
Meanwhile, the greener world, thanks to more abundant CO2, should be producing more oxygen.
CO2 is essential to human physiology – managing both respiration and acid/base balance – without which there would be no human growth
And the best plant food EVER!
I believe it is spelled “evah”.
Just sayin’.
Adam Show your proof that Oxygen is decreasing. That statement makes no sense. As more Carbon dioxide is entered into the atmosphere plant life increases producing more oxygen (this is why the dinosaurs were so big). As was stated in the video we are living in a low carbon dioxide timeframe (and lower oxygen) than for much of earths history of life on earth. Typically Carbon Dioxide will drop during ice ages when much of the plant and animal life dies reducing the oxygen/carbon dioxide volume as the oceans stop outgasing and carry more gases in solution, due to the colder temperatures.

CO2 is not put into greenhouses to warm them. It’s put in there to boost plant growth. Plants grow best at a CO2 level of around 3000 to 4000 PPM. They grow faster and are much more drought-resistant. Plants were essentially starving at the pre-industrial level of < 300 PPM. And, plant growth ceases entirely at about 150 PPM.
CO2 levels during the Carboniferous era were many times higher than they are now, but the temperature was roughly the same as now. Over the eons all that CO2 got sequestered in coal seams, shale oil deposits, corals, chalk, limestone and marble from the huge explosion of life that resulted from the abundance of CO2. Yet we never had a climate tipping point that made us end up like Venus.
As he states, we are already seeing the positive effects of just a little more CO2 in the atmosphere in a greener earth. If you are worried about oxygen depletion, ask yourself where that oxygen came from in the first place. Hint: it wasn't animals or volcanoes.
Lee: Don’t you see that Adam is one of those trolls is only concerned with the political meme of global warming and whenever he tries to show off all his “sciencey” knowledge falls way short. But by his understanding “the science is settled” and all you crazy people that don’t buy that must be some kind of retards that he is free to disdainfully dismiss with his grade school comprehension of issues in science. Sort of reminds me of the entry made trying to refute Dr. Spencer over at Skeptical Science wherein the commentator didn’t understand that human respiration involved the conversion of complex organic compounds in the presence of oxygen resulting in carbon dioxide. “Humans only exhale the carbon dioxide they inhale” is the exact quote as I remember.
Should we keep it a secret then plant cells respire, just like ours, all the time? They only photosynthesize in the presence of light. Of course they put out far more O2 than CO2, on balance…
Trees cause global warming. RUN!
CO2 levels during the Carboniferous era were many times higher than they are now,
What?
Where did you get that from?
http://www.catholica.com.au/misc/images2013/AJB-Global-Temp-Atmospheric-CO2-over-Geologic-Time_640x513.gif
IMO the benefit of added CO2 for most if not all plants reaches diminishing returns around 1300 ppm. That’s the maximum level used in commercial greenhouses, but many lower, ie about 1000 ppm.
But I’d welcome being shown wrong.
Mike,
Maybe he meant Cretaceous or Cambrian.
All those C Periods sound so much alike.
My bad. I should have more accurately stated ‘prior to the Carboniferous era’. I was trying to make the point that it was the huge explosion of plant and animal life during the Carboniferous era that was largely responsible for the dramatic reduction in atmospheric CO2 levels and the sequestering of all that carbon.
Um, mikeB, that picture you posted shows CO2 starting the carboniferas era at over 2000 ppm and not starting it’s drop until nearly half way through it. That’s like 40 million years. ^¿^
I agree with Sturgis … about 1300 ppm of CO2 in greenhouses is kind of the standard upper limit, beyond which there are diminishing returns.
Schitzree, you got the lines mixed up. Look more carefully.
According to the posted graph, which is an oldie but a goody, at the start of the carboniferous, CO2 was dropping fast and at about 1200 or so. It appears to have bottomed out somewhat higher than the level at the far right corresponding to the present era.
Black is CO2, Bluish is temp.
But this version left off the error bands, which are large:
http://rainbow.ldeo.columbia.edu/courses/v1001/co2.jpg
“Schitzree, you got the lines mixed up”
Whoops, yes I did. Thanks for the catch there, Menicholas. Hmm, in that case… well shoot, then where did all the carbon come from for the Carboniferous? It looks like we started the era with barely 1000 ppm and bottomed out only a quarter of the way through.
Adam sez: “CO2 is put into greenhouses to warm them”
What?
I think he might be confused by the fact that many greenhouses generate CO2 by burning natural gas, which produces heat as a bi-product. Under cool conditions that extra heat can be a plus; under hot conditions a minus. (As an aside, when CO2 augmentation is used, plants do better with higher temperatures.)
When did he say the Co2 is pumped in the greenhouses for the warmth? All I ever heard Patrick say is that co2 is increased inside greenhouse for better plant growth. Plants grow on c02 and prefer more that is currently in the atmosphere. As far as I know that is true and is not a new practice for greenhouse farmers.
Hi Charlie. PiperPaul was quoting Adam (comment at 10:08), not Patrick.
Oops! I see that Adam said that he said. Sorry. 🙂
yeah I know. we posted at the same time
Adam, you needed stronger coffee before your chemistry class.
“co2 is important to plant growth, but not to human growth” Adam wrote. That might be a new winner for alarmist qoutes on here. Ok. moving along then.
I am pretty sure that he did not say adding CO2 would “warm” the greenhouse.
Adam said it in a comment above (10:08), not Patrick.
Again (as above) I realize that Adam said that Patrick said. My mistake. Sorry. 🙂
Adam,
A more scientifically ignorant, easily refutable comment has never been made here on WUWT as yours here (at 10:08 am).
As others here refute your O2 fallacy, the physics of your greenhouse mechanism for greenhouses doesn’t apply to GHG heating.
Calling CO2 a “greenhouse gas” is in reality a poorly choosen description of the physics of CO2-climate radiative energy forcing.
Adam July 28, 2015 at 10:08 am
“CO2 is important to plant growth, but not to human growth”
Where do you think food comes from? All the food we eat comes from CO2 via plant photosynthesis – which also produces O2 – or animals that eat plants.
In addition, the concentration of CO2 in a normal human body is ~56.000 ppm. pCO2 averages about pCO2 = 40-44 vs atmospheric pressure =760, or CO2 ~5.6% = 56,000 ppm; and it’s kept their by immediate changes in “breathing”, as necessary, and changes in the concentration of HCO3- to maintain the right pH ~7.41-7.43 for all chemical processes necessary to keep us living and growing!
Adam, you are thoroughly saturated with “Carbon” and if I was you, I’d recheck everything I think I know! CO2 is not a “toxin” or a “pollutant”.
“56,000 ppm” is the ~correct number
CO2 is not put in greenhouses to heat them up. The heat produced by the process of making CO2 is what heats up a greenhouse. The greenhouse effect exibited in a greenhouse has nothing to do with CO2, it is the building that produces the greenhouse effect (hence the name). As for the non-sence about decreasing O2, you need to give your head a shake. The quantities are not even comparable.
No motivation? So, why do the warmists employ repeatedly massaged, recalculated and re worked land based thermometer data to obscure objectve temperature data from satellites? Why do they crow about 0.1 degree “records” when the margin of error is much larger than that. It seems the climate science is very influenced by the need to support the world wide political movement for reductions in CO2 emissions. And that movement is itself an outgrowth of the modern secular religious belief that modern civilization has “failed”, that the developed countries are “guilty”, that we need to return to a mythical simpler age. And then you have to consider how funding for climate science is controlled and how few gatekeepers in the form of reviewers of research papers would be required to produce a confirmation bias throughout the cliamate science field.
” He says CO2 is put into greenhouses to warm them and boost growth…”
He doesn’t say anything about “warming”, and you don’t buttress your argument by mischaracterizing his.
“He doesn’t say anything about ‘warming’ “, except “warm them”. Got it.
Adam, please try to grasp reality about growers using CO2. It’s got absolutely nothing to do with raising temperature. You will find no energy savings by boosting CO2 levels, only faster growth with less water. In fact, the generator is not a big source of heat so it increases utility costs slightly but that’s very recoupable with the increased harvest.
“CO2 is important to plant growth, but not to human growth.”
You see the level of idiocy it takes to believe in CAWG?
And you want to argue with this “mentally challenged” crowd?
To debate with ignorant fanatics?
Being respectful to parasites that rob you blind?
Good luck.
Just don’t call them ‘retards’ – that wouldn’t be politically correct. I like to call them Climate Scientologists. Sounds kind of ‘sciency’ and religious all at the same time.
I call them Gang Green. I like Climate Scientologists, though, that label is very appropriate.
“Alexander Feht July 28, 2015 at 2:13 pm”
Hey, these “mentally challenged” people are the best they got! And they give arguments and “facts” that need to be answered – since they’re seen by potentially everyone in the world – no matter how wrong they are. And they provide us with free target practice!
Calling them Climate Scientologists may be a little too subtle, though, on the humor scale. It’s not quite as in-your-face as calling someone a Denier. Although once they get the implication, and realize you intentionally used that word rather than the word Scientist, oh man, do they get offended! 🙂
Adam, you and your comrades will still be prattling on about global warming when you’re up to your eyeballs in snow…….Go and study some proper science!
“He says CO2 is put into greenhouses to warm them and boost growth (during cool climates I might add). This is why it is called the greenhouse gas effect.”
Adam,
Wrong, wrong, and wronger still.
You may have posted the comment with the least amount of actual truth in it in the history of the internet.

Too bad, really. I appreciate the insight, in a perverse way, into the sometimes inscrutable “intellect” of the warmista mind.
hahahaha omg did he really say they pump CO2 in to warm up the greenhouse. Godsdamnit man LISTEN… Dr Patrick did NOT say anything about CO2 warming the greenhouse. GAHHHHH is there anything so dumb as those that hear but do not listen????
Commercial greenhouse are not warmed as a result of pumping CO2 in to them.
Its called the Greenhouse effect because of the glass letting the light in but at the same time retaining the temperature (SHEEEEEEESH!!) – nothing whatsoever to do with the CO2 which is added to speed up plant metabolism due to increased photosynthetic ability. The insulating effect in such a small area is completely negligible compared to the glass and has nothing whatsoever to do with the reason they add it
Plants “breathe” in carbon dioxide & “breathe” out oxygen: near zero carbon dioxide emissions would be a disaster, therefore, for both plants & non-plant life. Motivation: Money mostly
Wow! Astonishes me how the flora and fauna of this world survived for centuries, millennia, æons prior to Man’s fortuitous arrival with his industries and their life-preserving carbon-emissions! Man arrived in just the nick of time! Thank GOD!!
Although I’m a little puzzled as to how the Earth managed PRIOR to industrialization….
Hmmmmm….
Maybe one of you Einsteins, you Newtons, you veritable Hawkings and Galileo’s can scratch your heads and come up with the answer to this fascinating enigma!
In the meantime, to feed my plants and preserve the planet I shall run my car 24/7 in the driveway. Gasoline is expensive, but it’s the least I can do. God forbid we RUN OUT OF CO₂!!!
Bless you! You do the God’s themselves’ work!
It’s too bad you came in dripping sarcasm, certain that everything you believe is correct. Had you asked your several implied questions seriously, and listened to the answers with a mind prepared for enlightenment, you might have actually learned something about how the world works.
Like greenhouse operators, serious aquarium hobbiests also bubble CO2 into their tanks for the same reason.
Generally speaking, bubbling does not dissolve in the water. It turns the water over exposing it to air, allowing more oxygen (etc.) to dissolve into the water. (For that matter, an undergravel filter does this without any bubbles involved. I always added a layer of floss under the gravel as a medium for bacteria, When exposed, it was always quite white, thanks to the bacteria culture.)
This is very nicely done. It has all the AGW cultists in the FB discussion groups all bent out of shape so you know it is good.
Truth is a very rare commodity in climate science and unheard of inside the beltway.
After posting Dr Patrick Moore’s video on my Facebook I saw this posted by one of my Facebook friends. Any thoughts on this “technology” – cost and claim to re-make fuel out of it??:
I have a number of trees that I’m sure are far more efficient at capture and storage, and many of them were purchased as seedlings for 12-15 cents a piece.
Uses the word “carbon” a lot, shows backlit water vapour and dense black unlikely something “spewing” from “smokestacks”.
I suspect this is a New Age Perpetual Motion Machine as the electrical power needed to run the fans (look Ma, no wires!) and especially to compress CO2 to liquid form is major. Probably can extract money very handily though. See Jo:
http://joannenova.com.au/2015/07/wait-til-you-see-these-numbers-on-carbon-capture-and-storage/emailpopup/
Correct. It is a perpetual motion machine, and a very badly designed one at that. Impossibly inefficient with huge losses in every cycle.
Your first problem is the very low concentration of CO2 in the atmosphere. When you concentrate up from 400 ppm (0.0004%) to bulk 100%, you are fighting against the concentration gradient all the way. The entropy of the system is driving to process against you. You can do it but there is a big energy cost to pay for this.
Second, you can use CO2 as an organic synthesis starting material, but it is probably the worst, most difficult feedstock that there is.
In short, you can do most anything you want, IF YOU HAVE ENOUGH ENERGY. And you do not mind dealing with really complex, difficult chemical pathways.
All that, just to make plants CO2 stressed? Why bother?
Tony L.
CO2 constitutes 0.04% of the atmosphere (4/100th of 1 percent). Not 0.0004%.
Right.
Too many zeros.
I wonder why the unit ppm is used instead of ppb or how about ppt? Oh no we’ve got 400 MILLION parts per trillion of them, that can’t be good. Wait how about 0.04 parts per hundred. Whew.
CO2 is an awful feedstock because the carbon is completely oxidized.
In order to be useful as a fuel, it needs to be reduced.
This takes energy.
It exists in low concentrations in the atmosphere.
Plants absorb CO2 and use sunlight as a fuel, and chlorophyll as a catalyst to turn CO2 and water into glucose.
Everything else is then synthesized by plants from that glucose.
The fact that plants can use such a low concentration of this trace gas to do what they do is one of the enduring miracles of the terrestrial biosphere.
J.PP: go here: http://joannenova.com.au/2015/07/wait-til-you-see-these-numbers-on-carbon-capture-and-storage/#more-28236
If CCS doesn’t make sense from power stations, any carbon capture for commercial purposes from the atmosphere is ridiculous in the extreme.
Efficienty? Yes. Cheaply? Not on your life. One of these for every 20 cars? There are over a billion cars and trucks, not to mentions ships and planes, pipeline compressors, backup Diesel generators. “Yes, thank you, I would like 60 million of these devices, could I have them delivered? Where? Everywhere, of course…”
Sheer lunacy. More air gets filtered through my colon than they will be able to filter with their carbon capturing machines. I am absolutely appalled at the current world of “magic” solutions and religious adherence to AGW.
Where’s my witch-doctor? I feel a headache coming on…
With no commercial market for probably the world’s most expensive source of CO2, I can only assume they are waiting in expectation of a huge government contract.
CO2 as the product of combustion is at the bottom of the potential energy well. Lifting it up in potential energy by separation from oxygen requires vast quantities of energy. This credulous video makes no mention of energy requirements and conversion efficiency to take CO2 at a very low concentration in the atmosphere and convert it to an energy dense hydrocarbon fuel. There is some truth to the notion that the CO2 scrubbers could be located anywhere on earth and could theoretically be a good match for intermittent and unpredictable solar and wind generation. But where is the mention of the scale of solar or wind facilities required to run a meaningful CO2 extraction program. CO2 recovery and possible sequestration is a fundamentally an idiotic idea with a solitary goal to bring in research grants.
Excellent presentation, my only nit-picking point was that I thought that there was a period in Earth’s history when CO2 levels were 19-20x higher than today.
Our Patrick Moore (sadly deceased) thought AGW was nonsense as well; so much for the consensus!
I think you got the wrong Patrick Moore there. The deceased Patrick Moore was an English amateur astronomer. The very much living Patrick Moore is an Ecologist. The mistake thanks to Google ranking.
Aussiebear. By our Patrick Moore i did mean the UK TV presenter and astronomer as opposed to the American Patrick Moore from Greenpeace. The former agreed with the latter wrt to AGW and publicly stated it was nonsense.
I am sure that if the warmists can get film stars and psychologists to endorse AGW we have more than a precedent to use ecologists and amateur astronomers to counter AGW.
Canadian Patrick Moore – from northern Vancouver Island and at the University of BC at the same time as I was many moons ago.
Though CO2 is good for plants, there is a major problem with his argument. If CO2 levels increase further, many of our coastal cities will be flooded as sea level rise and the increase in temperature of the atmosphere will lead to larger more damaging storms. Is that the world we want?
Yep, I’m looking forward to my beachfront property here in the hills of Vermont …
Luke..we have no control. It doesn’t matter what we want, we’ll have to deal with what we get.
We do have control if we choose to take it. It is pretty simple, we have to drastically reduce CO2 emissions.
Luke, this preposterous argument was just dealt with a couple of days ago.
http://wattsupwiththat.com/2015/07/26/dr-james-hansens-recent-alarm-of-catastrophic-co2-driven-sea-level-rise-looks-to-just-be-spurious-correlation-in-his-own-mind/
In 1988-89 Hansen predicted that in 20 years the West Side Highway in New York would be underwater. That would have required a rise in sea level of 10 feet.
More recently Hansen moved the goalposts and said the Highway would be underwater in 40 years. We are now 25 years into his prediction and sea-level has risen 2.6 INCHES. Still about 10ft to go in the next 15 years.
BTW, 2.6 inches in 25 years is essentially the same rate of decadal rise as was seen since data recording began is the late 19th century.
Luke, you have heard the alarmist predictions about sea level rise and have taken them for gospel, but the predictions have been falsified. They are wrong. In error. In real science, that means it is time to seriously review your theory, not just keep repeating the same dis-proven ideas ever more loudly.
Luke, Cannot tell if you are serious. Hansen’s newest stuff has been adequately debunked on a previous thread here, and over at CE. Plus a very specific two pronged response to reviewer Archer’s inane comment at the paper’s host site.
Catastrophic Climate Change has been in Poe’s Law territory for some time now.
Are you seeing any evidence of that?
Even your much vaunted IPCC says there is no statistical trend of increasing ‘storms’,,,,All measured storms from tornadoes to hurricanes show no increasing trends…in fact it can be argued they are decreasing. More lies from the Lukester. I suggest you go to your basement and lock all your doors so the weather-boogeyman doesn’t get you.
Luke,
Can you please present the empirical evidence that demonstrates how CO2 directly causes flooding and “more damaging storms”? I mean there’s probably a simple graph that shows an acceleration of both the above items that marches in lock-step with CO2 increases. It would also be nice to see the breakdown of the natural:anthropogenic influences. Don’t forget to stay only within the CO2 parameters.
Thanks.
Adam B.,
Below are urls for a NOAA report and peer-reviewed publication showing an exponential increase in flooding of coastal US cities using empirical data. The evidence for increased warming causing an increase in sea level (through thermal expansion and melting of ice sheets) is so ubiquitous I will let you find it.
Here is the NOAA study showing an exponential increase in coastal flooding over time in US cities.
http://tidesandcurrents.noaa.gov/publications/NOAA_Technical_Report_NOS_COOPS_073.pdf
And a peer-reviewed paper, take a look at figure 4.
http://onlinelibrary.wiley.com/doi/10.1002/2014EF000272/pdf
Read up on Nils-Axel Morner . Sea levels rise and fall tens of centimetres over hundreds of years
http://wattsupwiththat.com/2013/07/31/the-marshall-islands-and-their-sea-level-changes/
Some of the concerns over rising sea levels occur due to land subsidence.
I’m pretty sure we have some inside trolls here on this video. I realy hope that’s not the case but nothing you can I guess.
Of course, if sea level rises, there will be coastal impacts, but you are making 2 assumptions that have not been proven to be true. One is that CO2 has something to do with causing higher global temperatures, the other is that a warmer climate automatically leads to more violent storms.
The historical records do show a correlation between CO2 and temperature, but it’s a trailing one. Temperature thus drives CO2, not the other way around as the CAGW alarmists would have you believe. Warmer seas outgas C02 and there is a significant lag between the onset of warming and the beginning of the rise in CO2 levels – every time.
The second premise, that warmer climates produce more storms has just not materialized. If anything, storm severity and frequency has actually lessened.
If sea levels rise due to warming, but the warming is almost all naturally-caused. there’s not a lot we can do about it other than move to higher ground.
In politics they always say ‘Follow the money’; in climate science, it should be ‘Follow the sun.’
Melting the Greenland and Antarctica ice caps would take thousands of years. They are big huge thermal masses and heat sinks, they are not going away anytime soon. Meanwhile, sea level rise continues along at 8 inches per century, just as it has for the last 6,000 years. (Sea level rise was much greater than that, earlier)
It seems that there is much about CAGW that you have not been told. Stick around, and keep your calculator handy.
Is this for real?
Luke,
You said:
“Though CO2 is good for plants, there is a major problem with his argument. If CO2 levels increase further, many of our coastal cities will be flooded as sea level rise and the increase in temperature of the atmosphere will lead to larger more damaging storms. Is that the world we want?”
CO2 levels are increasing steadily, and oceans are not rising any faster than they were before much CO2 was added to the air.
There is not a single shred of objective and verifiable data to support your statement.
If you disagree, post some data and sources to back up your statement.
FYI, you are sorely and tragically mistaken in your belief.
Cheer up, the world aint ending, and CO2 aint bad!
Aren’t you relieved to have that burdensome weight lifted?
If you are not, you may be ill.
Sorry Luke, Adam beat you to it as the first idiot to troll here.
Luke,
Sea levels have been generally rising since the end of the last ice age. The sea level rise is not accelerating as one would expect if the rise was influenced by atmospheric CO2 concentration. Stop worshiping at the Gorical and look critically at the actual sea level records.Want to know when to be scared? Be scared if the sea level starts to drop, that means we are heading into either a mini ice age or event he full blown descent into the real thing.
The warmers are winning the media blitz regardless of what we believe or gets posted here.
It seems that way, but the majority of the general public cares not a wit about this subj.
The problem is that we can easily wake up one day and find that the Brave New World has been instituted while we weren’t paying attention. A population with only 10% to 15% fanatics can easily manipulate and control the 85% to 90% who are ambivalent. Just look at history and current events in the ME.
Unfortunately, we are dealing with an administration that cares not a whit about what the public thinks.
Yes. That being said, I am tired of trying to comment on a false report and the same two rabid warmists resort to name calling, etc…. I did manage to get over on one guy at a site where you had to log in via Facebook. Busted the guy out for flying to Barcelona when he could have used video chat. Took him about 3 hours to respond to that. Heh.
And as if to illustrate my point, here’s the man himself:
http://www.nytimes.com/2015/07/29/us/president-obama-expected-to-reveal-new-climate-plan-next-week.html?_r=1
I really don’t think so, I’m seeing a plurality of activity in the blog-o-sphere that attacks the fear mongering pretty directly. Further, MSNB and CNN, the two cable nets that are most left leaning, are toast, and CBS had to pull it’s editorial policy more back to center to keep their news audience from eroding. Several well executed polls are showing that while many people believe that AGW is real about 60% in the U.S. now believe that the hype is overblown, and the consequences are modest to none.
I’m noticing the same, Mark. Some years ago, for instance, comments in newspapers were heavily alarmist and now I find it more the other way with a lot of criticism coming in. People everywhere are getting fed up with the hype and the lies. They might not be interested in the subject of global warming, but they don’t like being lied to and they don’t like the destruction and the cost that comes hand-in-glove with climate policies.
I agree with Mark and A.D.
I noticed the same shift from mostly warmist to mostly non-warmist comments on a large number of different sorts of comment threads and discussion venues.
And a lot of people just clam up because, after all, who really likes to get into an argument with the sort of people the warmistas have shown themselves to be?
I am seriously considering going political for the first time in my life, and once the election season really cranks up, volunteering and going to work for a candidate who promises to fire all the liars.
I strongly believe that many people are just holding their tongues and waiting to vote, at this point.
Where on earth is Prager University; typo for Prague, perhaps?
virtual, unaccredited – doesn’t grant any degrees apparently and doesn’t want to – free, 5 minute “courses”:
http://www.prageruniversity.com/index.php
Bubba, I thought they taught all there was to know about spaghetti sauce.
Oh wait… that’s Prego University Never mind.
No there’s a curriculum I can sink my teeth into. ^¿^
CO2 is plant food sounds dumb. Absolutely necessary component, building block, compound or something like that for life on Earth. I ginned this one up a while back, maybe someone can do better.
http://oi61.tinypic.com/2hcgvgi.jpg
Point out that the so-called agricultural green revolution is in no small way a product of increased CO2 in the atmosphere.
CO2 is plant food, along with water and sunlight. What we call “plant food” in the commercial sense is more akin to plant vitamins, to extend the analogy to human food a little further. Substances needed in small amounts on a regular basis.
Menicholas, I’d come out somewhere between Steve Case and yourself. Thermodynamically speaking, CO2 isn’t a food because no “work” (Gibbs Free Energy) can be derived from it. A better word is building block. The “food” required by a plant in this sense is purely sunlight.
Nonetheless CO2 is an absolutely essentially building block. It is needed in bulk, and it is expensive for the plant to obtain because of its scarcity in the atmosphere. Much of plant physiology and plant water use is organized around the need to bulk harvest rare CO2 from the atmosphere.
In the common parlance I have no problem with hearing it referred to as “plant food”.
How about “The air plants breath.” Simple and to the point.
And the plants have been ‘short of breath’ for a very long time now. And they’re still a few hundred ppm short of ‘breathing easy’.
Prager University is a website run by Dennis Prager, who is among other things, a conservative talk show host.
CO2 is an essential and life giving gas. Of course, so what?
Then doubling it in a blink of a moment is such a stroke of genius, eh?
No unanticipated negative side effects when poking the system, there seldom are.
But here the science is just settled, right?
Promising to see WUWT suddenly recognise this “negligible trace gas” as important.
That was not so hard, was it?
GeoEng,
your commnet shows a total lack of familiarity here that AW, and his regular cast of contributors, and most commenters here are accepting of the fact increasing atmospheric CO2 provides additional radiative forcing on the atmosphere, one that should raise temps. The pertinent scientific question is, “how much?” Typically described as climate sensitivity, both equilibirum and transient.
The role of water vapor reponses, clouds, and humidty changes in response to elevated IR forcing though is conveniently dismissed as unimportant by the modellers to arrive at their politcally useful results in order to demonize CO2 in their Chruch dogma.
Joel O’Bryan,
Yes, sorry for my total lack of familiarity. It was a bit harsh. Lukewarming it is. It’s a slippery slope that one I’ve heard.
And yes, they’re really devious those politicized climate model algorithms.
GeoEng was probably just parroting what he’d been told about WUWT by his emotionally-invested, politically-motivated, group-thinking peers.
PiperPaul,
Spot on, clever. 😉
“GeoEng July 28, 2015 at 2:07 pm”
Geo, you seem to be confused about what you posted to start this thread. If you think it’s confusing me, it’s not.
GeoEng July 28, 2015 at 11:20 am
It hasn’t doubled yet, but so far, “Where’s the [poisonous] beef?” A 100% Prediction Failure Rate for the hypotheses expressing catestrophic “CO2-Climate Change” doesn’t get me very worked up.
catastrophic
JPeden,
Not getting worked up, our motto. 🙂
Anyway, on significantly customizing the chemical composition of the atmosphere. I wouldn’t recommend that.
I’m conservative, not irresponsibly optimistic.
geoeng,
You would prefer going back to an earth where there were maybe a few hundred million people, tops, living hash, short and brutal lives of desperate poverty and random early death?
Not me.
Speak for yourself please.
You can go revert to an agrarian preindustrial lifestyle. No one stopping you.
BTW, what have you got against the trace gas which is responsible for all life on Earth, and is the indispensable base of the entire food chain of the biosphere?
GeoEng,
I gagged a bit when I saw you describing yourself as “conservative, not irresponsibly optimistic”.
You are ready to impose radical changes to the economy, and a radical reduction of our liberties, based on falsified climate hypotheses, and unproven, unworkable, not invented yet, technologies.
How is that “conservative”? How are you not “irresponsibly optimistic”?
Menicholas,
You know that’s a total misinterpretation of what I said. http://dilbert.com/strip/2015-06-07
I’ll prefer the Holocene over the any other epoch. It’s where civilisation evolved. It’s stable, we’re adapted.
I keep hearing “the earth had X times CO2 N time ago”. What a silly statement.
Well, you go first!
I like it here.
I love CO2, I’ve said nothing else. You’re projecting.
TYoke,
When did I mention policy? You’ve got all mixed up.
Accidentally rising CO2 to an unknown level. How’s that so responsible?
I’m risk averse. Then I’m the radical one? Oh man.
GeoEng,
You’re right. You didn’t mention policy. You said about a rising CO2 level only: “I wouldn’t recommend that”. We’re all thrilled to have your “recommendation”, but guess what? CO2 levels ARE rising, and they’re going to continue to rise. Most of the increase is now coming from China and India, and they’re not going to stop.
Now what? No further thoughts?
TYoke,
I think you’re right and CO2 levels will just keep rising. And we’re not wired for fixing this.
How it’s going to play out? Well, you tell me.
If the energy budget of the troposphere is in convective equilibrium, rather than radiative equilibrium, the ~1% increase in forcing from GHG may not produce any change at all in air temperature. It may just increase tropical precipitation by a percent or two.
Convective equilibrium seems much more likely, given the entire lack of any empirical evidence of a GHG effect on climate so far.
Pat Frank,
And it’s more to CO2 than a GHG effect, as Dr. Patrick Moore explains. And it’s a lot of unknowns.
We don’t know how the composition of the biosphere would react. Some species might gain more than others.
This would mean redefining the rules of the game, impact biodiversity, globally.
It’s for sure an interesting experiment.
That no one that no one is going to change, so why think about a real problem?
Menicholas,
Well, you got me there. Outsmarted.
Sorry, my computer got blinky, had to log out. Meant to say …why not think about a real problem?
I am glad you noticed that. It is amazing how many people think the smallest disturbance will have some catastrophic effect when we already know from past history this is not the case.
gregf101,
“Past [geological] history” had no civilisation.
Patrick Moore thinks the earth is noticeable greening. There is a significant effect, but the science is not settled. “Catastrophic” is you implying.
A “smallest disturbance” of 70% increase, for an important life-giving trace gas.
Happy to amaze you.
GeoEng.
Odd. I had a teacher in 1956 on exchange from the United States who was teaching us backward Canadians about biospheres and plant breeding and CO2 way back then, 59 years ago. Still remember his name, Mr. Kirby. And I grew up in a town that had severely modified the air through 50 years or so of sulphur emissions. We learned that these processes are highly reversible and some 60 years on, that valley that was barren and rocky is now tree covered and verdant. I really can’t believe that a 0.04% increase in CO2 over the next 100 years will be an issue. But then, I suspect I have been around a bit longer than GeoEng. But GeoEng, if you took any of the same geology courses I took in engineering, you surely must have some doubt about what you are saying as we know the world over and different times have had much different local and regional chemistries. And we have done a darn good job of managing many of our real pollution problems. There is much more to do, but CO2 isn’t one I worry my grandchildren about. Over fishing, education, feeding the poor, medicine and other like things yes. Climate —> not anywhere near the top of the list for them though I read and have read about it since I was a single number 60 years ago as I found/find the history interesting. My grandchildren have been taught “Carry it in, carry it out.” as I was. Yet when I see the garbage left by “environmentalists” after their protests, I smell an oxymoron. Like those on the Portland bridge today.
WJD, P.Eng.
Or maybe you are just kidding?
Wayne Delbeke,
“I really can’t believe that a 0.04% increase in CO2 over the next 100 years will be an issue.”
“You have to run the numbers”, quoting Roy Spencer at Heartland’s ICCC6.
Small numbers don’t look very significant, but I guess one can’t do science by eyesight alone. I get it’s unbelievable.
By the way, 0.04% (400 ppm) is the level of CO2 today. In 100 years, 0.06% (600 ppm) would be more likely, keeping today’s release rate.
“.. different times have had much different local and regional chemistries.”
400 ppm, now that’s a long time ago. Very different indeed. And the speed of change are unprecedented.
I agree, there are more imminent dangers to human society than CO2 rise, take nuclear weapons for one.
And those “environmentalists” should get their act together and clean up or get fined.
I’m curious, how did you find the greening of the planet believable considered the small change in CO2 levels?
At what level of CO2 would this become an issue at all?
Maybe I just haven’t been around long enough.
Luke,
Hi Luke,
