“It doesn’t make any difference how beautiful your guess is, it doesn’t matter how smart you are, or who made the guess, or what his name is…
“If it disagrees with experiment, it’s WRONG. That’s all there is to it.”
Climate models disagree with experiment, therefore they are wrong. Therefore, the hypothesis that our CO2 emissions cause significant global warming is wrong.
