It is like a religious mantra to him. I have read it from beginning to end and I can't imagine which part of it he beleives constitutes proof of anything. Nothing there mentions any experimental proof, or hard observation, or repeatable result of any kind. The mental state required to actually believe that that represents proof is just sad and an indictment on the public school system of wherever he went to school.
Like you don't have your own mantras! What about "But CO2 is just a trace gas". Maybe so, but it certainly doesn't mean it can't trap energy. Trap enough and temps will rise. Don't see how you get around that one. In all your posts you never seem to explain that. WHY??? My guess is because your objections are mainly political, since neither science nor logic are on your side, as evidenced by your ridicule of the Greenhouse Effect, a well-established scientific principle.
