This also comes from "The Great Global Warming Swindle and can be seen here:
The role carbon dioxide plays in the warming of the Earth's atmosphere is crucial to the entire debate about global warming and what (if anything) we can do about it.
The Kyoto Treaty is based opon it. When people speak or write about "greenhouse gases" and "carbon emissions" that must be contained, "sequestered", eliminated, capped, and credited.......what they're talking about is simply carbon dioxide, CO2, the gas we exhale with every breath, and which plants use in their growth processes. We must learn everything we can about CO2 if we hope to understand the significance of the laws and actions being proposed and imposed upon us.
CO2 & Temperature
The ice-core data is frequently cited as principal evidence to argue that CO2 is the earth’s main climate driver. It is, in a way, the jewel in the crown of the theory of man made global warming. But the ice-core data does not show that CO2 drives climate. It shows, very clearly, that variations in temperature precede rises in atmospheric CO2 – not the other way round. The two phenomena are divided by a time lag of several hundred years.
There is no evidence that CO2 has ever ‘driven’ the climate in the past, nor is there any compelling evidence that it is doing so now.
According to global warming theory, if an enhanced greenhouse effect (from increased levels of CO2 or indeed any other greenhouse gas) is responsible for warming the earth, then the rate of temperature rise should be greatest in that part of the earth’s atmosphere known as the troposphere, specifically in the tropics. And yet the observations, from weather balloons and satellites have consistently shown that not to be the case. I urge readers to look at the Christy et al papers below. The latest one was recently published in the Journal of Geophysical Research (2007). This may seem like a rather technical issue, but it strikes at the very heart of the theory of man made global warming.
