Come on, man, you're a smart guy. Earth's climate is a chaotic nonlinear system. Past data cannot predict future changes in such a system, that's why we can't predict weather changes more than a week out with any degree of certainty. Climate "scientists" are pretending they can forecast changes in global temperatures centuries from now; how about they demonstrate 99%+ accuracy for a 4-6 week prediction period first? They don't because they can't; trying to do so would destroy what little credibility remains in their prediction models that already have a terrible track record.
