FC, this is something important you should know. I haven't reached any conclusion with regard to how important man's CO2 emissions are in regard to climate! But I am definitely leaning toward the view that our CO2 emissions are less important than many have supposed. I've mostly just pointed out work that contradicts the Gore-Hansen viewpoint. And I have raised some questions. I don't consider the question of whether we are seriously affecting our climate with our CO2 emissions to be settled at all. Whereas you seem to be convinced that we are causing our planet to heat up to dangerous levels. I have no problem with disagreements. And frankly neither of our opinions are very important.
