In short, there IS no evidence that CO2 has ever caused significant warming on Earth when the concentrations were within 10-15 times of what they are today. Water vapor is, by far, the most important greenhouse gas in the Earth system. Water vapor accounts for about 95% of the greenhouse effect on Earth. Earth's temperature variations are much better correlated with the Sun's solar activity/sunspot cycle than with CO2 changes.-etl
THE ACQUITTAL OF CARBON DIOXIDE
by Jeffrey A. Glassman, PhD
ABSTRACT:
"Carbon dioxide in the atmosphere [historically] is the product of oceanic respiration due to the well-known but under-appreciated solubility pump. Carbon dioxide rises out of warm ocean waters where it is added to the atmosphere. There it is mixed with residual and accidental CO2, and circulated, to be absorbed into the sink of the cold ocean waters. Next the thermohaline circulation carries the CO2-rich sea water deep into the ocean. A millennium later it appears at the surface in warm waters, saturated by lower pressure and higher temperature, to be exhausted back into the atmosphere. Throughout the past 420 millennia, comprising four interglacial periods, the Vostok record of atmospheric carbon dioxide concentration is imprinted with, and fully characterized by, the physics of the solubility of CO2 in water, along with the lag in the deep ocean circulation.
Notwithstanding that carbon dioxide is a greenhouse gas, atmospheric carbon dioxide has neither caused nor amplified global temperature increases. Increased carbon dioxide has been an effect of global warming, not a cause. Technically, carbon dioxide is a lagging proxy for ocean temperatures. When global temperature, and along with it, ocean temperature rises, the physics of solubility causes atmospheric CO2 to increase.
If increases in carbon dioxide, or any other greenhouse gas, could have in turn raised global temperatures, the positive feedback would have been catastrophic. While the conditions for such a catastrophe were present in the Vostok record from natural causes, the runaway event did not occur. Carbon dioxide does not accumulate in the atmosphere."

The graph above represents temperature and CO2 levels over the past 400,000 years. It is the same exact data Al Gore and the rest of the man-made global warmers refer to. The blue line is temps, the red, CO2 levels. The deep valleys represent 4 separate glaciation/ice-age periods, approximately 100,000 years apart. Look carefully at the historical relationship between temps and CO2 levels (the present is on the right hand side of the graph) and keep in mind that Gore claims this data is the 'proof' that CO2 has warmed the earth in the past. But does this data indeed show this? Nope. In fact, rising CO2 levels all throughout this 400,000-year period actually *followed* temperature increases, lagging behind by an average of 800 years! So it couldn't have been CO2 that got Earth out of these past glaciations. Yet Gore continually and dishonestly uses this same data as "evidence" of a *positive* historical correlation between CO2 and temps. Furthermore, and importantly, the subsequent CO2 level increases (due to dissolved CO2 being released from warming oceans) never did lead to additional warming, the so-called "run-away greenhouse effect" that Al Gore and company continue warning us about. In short, there is little if any evidence that CO2 had ever led to any significant global warming when the levels were within 10-15 times of what they are today. -etl

"The above chart shows the range of global temperature through the last 500 million years. There is no statistical correlation between the level of carbon dioxide in the atmosphere through the last 500 million years and the temperature record in this interval. In fact, one of the highest levels of carbon dioxide concentration occurred during a major ice age that occurred about 450 million years ago [Myr]. Carbon dioxide concentrations at that time were about 15 times higher than at present." [also see 180 million years ago, same thing happened]:

So, greenhouse [effect] is all about carbon dioxide, right?
Wrong. The most important players on the greenhouse stage are water vapor and clouds [clouds of course aren't gas, but high level ones do act to trap heat from escaping, while low-lying cumulus clouds tend to reflect sunlight and thereby help cool the planet -etl]. Carbon dioxide has been increased to about 0.038% of the atmosphere (possibly from about 0.028% pre-Industrial Revolution) while water in its various forms ranges from 0% to 4% of the atmosphere and its properties vary by what form it is in and even at what altitude it is found in the atmosphere.
In simple terms the bulk of Earth's greenhouse effect is due to water vapor by virtue of its abundance. Water accounts for about 90% of the Earth's greenhouse effect -- perhaps 70% is due to water vapor and about 20% due to clouds (mostly water droplets), some estimates put water as high as 95% of Earth's total tropospheric greenhouse effect (e.g., Freidenreich and Ramaswamy, 'Solar Radiation Absorption by Carbon Dioxide, Overlap with Water, and a Parameterization for General Circulation Models,' Journal of Geophysical Research 98 (1993):7255-7264).
The remaining portion comes from carbon dioxide, nitrous oxide, methane, ozone and miscellaneous other 'minor greenhouse gases.' As an example of the relative importance of water it should be noted that changes in the relative humidity on the order of 1.3-4% are equivalent to the effect of doubling CO2.

Water Vapor Rules the Greenhouse System
Water vapor constitutes Earth's most significant greenhouse gas, accounting for about 95% of Earth's greenhouse effect (4). Interestingly, many 'facts and figures' regarding global warming completely ignore the powerful effects of water vapor in the greenhouse system, carelessly (perhaps, deliberately) overstating human impacts as much as 20-fold.
Water vapor is 99.999% of natural origin. Other atmospheric greenhouse gases, carbon dioxide (CO2), methane (CH4), nitrous oxide (N2O), and miscellaneous other gases (CFC's, etc.), are also mostly of natural origin (except for the latter, which is mostly anthropogenic).
Human activities contribute slightly to greenhouse gas concentrations through farming, manufacturing, power generation, and transportation. However, these emissions are so dwarfed in comparison to emissions from natural sources we can do nothing about, that even the most costly efforts to limit human emissions would have a very small-- perhaps undetectable-- effect on global climate.

Water Vapor Confirmed As Major Player In Climate Change
ScienceDaily (Nov. 18, 2008) — Water vapor is known to be Earth's most abundant greenhouse gas, but the extent of its contribution to global warming has been debated. Using recent NASA satellite data, researchers have estimated more precisely than ever the heat-trapping effect of water in the air, validating the role of the gas as a critical component of climate change.

Notice how we NEVER hear from the largely left 'scientific' community pushing this hoax of a single good thing that can come as a result of so-called global warming (allegedly man-made or natural). Instead, it's ALL bad news, according to them.
I gather what you mean is that increased CO2 will result in more vegetation and trees which in turn take-up CO2 in order to live. Great point.
CO2 creates a dramatic greenhouse effect on Venus -- where it is 97% of the atmosphere, versus 0.038% for Earth.
[Correlation DOES NOT = Causation!]
THANK YOU!
Just because I was at the bank when it was robbed does NOT make me the robber!!!
I understand but if the CO2 level is unprecedented that is worth noting and that is inconsistent with the point about ‘10-15 times’ that I mentioned.
Yes, I use this fact occasionally in debates with liberals. Unfortunately, many school kids are being led to believe that the two planets are similar in regards to CO2 and warming.
Why You Should Be Hot and Bothered About 'Climate-gate'
FoxNews.com ^ | November 24, 2009 | John Lott
Computer hackers have obtained 160 megabytes of e-mails from the Climate Research Unit at the University of East Anglia in England. These e-mails, which have now been confirmed as real, involved many researchers across the globe with ideologically similar advocates around the world. They were brazenly discussing the destruction and hiding of data that did not support global warming claims. The academics here also worked closely with the U.N.'s Intergovernmental Panel on Climate Change.
Professor Phil Jones, the head of the Climate Research Unit, and Professor Michael Mann at Pennsylvania State University, who has been an important scientist in the climate debate, have come under particular scrutiny.
Among his e-mails, Professor Jones talks to Professor Mann about the "trick of adding in the real temps to each series...to hide the decline [in temperature]."..."
Another professor at the Climate Research Unit, Tim Osborn, discusses in e-mails how truncating a data series can hide a cooling trend that would otherwise be seen in the results. Professor Mann sent Professor Osborn an e-mail saying that the results he is sending shouldn't be shown to others because the results support critics of global warming. Time after time the discussions refer to hiding or destroying data. ..."

INTERVIEW-Climate science untarnished by hacked emails-IPCC ( From Nov 27 )
*********************************EXCERPT INTRO***************************************

* UN climate panel report "in no way" tarnished
* Review process makes bias impossible
LONDON, Nov 26 (Reuters) - The head of the U.N.'s panel of climate experts rejected accusations of bias on Thursday, saying a "Climategate" row in no way undermined evidence that humans are to blame for global warming.
Climate change sceptics have seized on a series of e-mails written by specialists in the field, accusing them of colluding to suppress data which might have undermined their arguments.
The e-mails, some written as long as 13 years ago, were stolen from a British university by unknown hackers and spread rapidly across the Internet.
But Rajendra Pachauri, who chairs the Intergovernmental Panel on Climate Change (IPCC), stood by his panel's 2007 findings, called the Fourth Assessment Report (AR4). "This private communication in no way damages the credibility of the AR4 findings," he told Reuters in an email exchange.
This report helped to underpin a global climate response which included this week carbon emissions targets proposed by the United States and China, and won the IPCC a share of the 2007 Nobel Peace Prize.
The e-mails hacked from Britain's University of East Anglia last week showed scientists made snide comments about climate sceptics, and revealed exchanges about how to present the data to make the global warming argument look convincing.
In one e-mail, confirmed by the university as genuine, a scientist jokingly referred to ways of ensuring papers which doubted established climate science did not appear in the AR4.
Pachauri said a laborious selection process, using only articles approved by other scientists, called peer review, and then subsequently approving these by committee had prevented distortion.

But-but, the 'data'.
It's all been destroyed.
Darnit.
LOL!!
It is good to continue to circulate these articles and links to other sites so that people viewing FR site will get the message and be curious to learn more.
I’ve been practicing exhaling only.
It’s working out okay.
My part for the planet.
But we exhale carbon dioxide. You know, the greenhouse gas that the lefty one-world government, enviro-Marxists warn us about, despite the fact that there is ZERO evidence for it being a problem on Earth.
