Skeptics cite skeptical scientists? So what. I've been reading about the human caused global warming issue since about 1980. At first I bought the theory. CO2 is a greenhouse gas. We're adding CO2 to the atmosphere. Therefore, we ought to be heating up the climate. Simplistic thinking. As I've read more of the years, I've come to understand CO2 is a minor GHG. Its been far higher in the atmosphere in the past (hundreds of millions of years ago) than at present. Citing the last 400K years or 2M years means citing a period dominated by ice ages. I am also struck that examination of global temperatures and CO2 concentrations in ice cores show CO2 increases have FOLLOWED temperature increases, not preceded them. The opposite would be the case if CO2 was a driver of temperature. How do you explain the ice core data?
