It was not a world of CO2. It was a world of methane. Plant and simple animal life converted this earth from a methane sphere into the one that could support advanced animal life. By that time, vast amounts of carbon was locked into earth or deep in the oceans.
One additional problem with melting ice caps - significant amounts of methane (another global warming gas) would be released.
Ten nations recently completed analysis of an 800,000 year ice core. It has again confirmed that increase in global warming gases is unprecedented in earth's history. In but 17 years, we have increased global warming gases in what previously took earth - during a most rapid change - 1000 years.
There is no doubt that man is changing the atmosphere. Only remaining question is how fast and how destructively. So George Jr's administration quashed a large number of environmental research satellites. Clearly science (environmental, quantum and nuclear physics, stem cell, public school education) is also on the George Jr enemy's list.
