No Kirk, I have never said that CO2 does not cause any warming of the earth. You claim that humans are causing global warming by the amount of CO2 they've put in the atmosphere. Considering the earth has warmed numerous times before (whether CO2 initiated or not), that doesn't mean that it's caused by humans. Look up pine-beetles. LIke I've said a million times before on these boards, I do believe the earth may be warming, and I do believe that humans do contribute to green-house gases, but they are not the main source or the main cause of the warming of the earth. You are attributing way too much to humans when the earth's climate has changed dozens of times without human help. You cannot PROVE that humans are causing global warming.
