For someone supposedly committed to reason and logic, you don't seem to have much familiarity with its application. "For example, for global warming I recommend you google Richard Lindzen and read what he has to say about it."

Lindzen's iris hypothesis has not played out. In fact if the climate had significant strong negative feedbacks we would never have seen the onsets or ends of ice ages, which were caused by relatively small changes in radiative balance as the earth's orbit varied.

The fact that you later cite the Oregon Petition as demonstrative of anything further undermines your credibility. Scientific American said "Crudely extrapolating, the petition supporters include a core of about 200 climate researchers‐a respectable number, though rather a small fraction of the climatological community." Which agrees with recent surveys showing ~97% of those who study the climate accept AGW. For a more entertaining take on the petition see here (video).
