In the Goodness of Time

Installment 3, from the Friends Of Science
Myth 3: Human produced carbon dioxide has increased over the last 100 years, adding to the Greenhouse effect, thus warming the earth.

Fact: Carbon dioxide levels have indeed changed for various reasons, human and otherwise, just as they have throughout geologic time. The CO2 increase was only 0.4% over the last 50 years, rather than the 5% per 100 years quoted by Kyoto. However, as measured in ice cores dated over many thousands of years, CO2 levels move up and down AFTER the temperature has done so, and thus are the result of, not the cause of warming. Geological field work in recent sediments confirms this. There is solid evidence that as temperatures rise naturally and cyclically, the earth naturally produces more CO2 as a result.
Should we conserve forests and minimize consumption of natural resources? Yes! Should we damage our economy without hard evidence? Is that wise?
