I am glad to see that the true believers have refuted this. These things just keep popping up all over the place. Since you call the other side deniers I hope that you don’t mind that I refer to you as true believers (Actually I do hope you mind) There are three good models that all predict global warming. Each model predicts a different amount and I believe all three results.
Until we get some unimpeachable data, this argument will continue without end.
