re: What are your reasons for believing climate change is "a hoax"

The conspiracy is censoring those scientists who would do work which disagrees with andropomorphic climate warming being a significant factor in overall global warming, or the effects of such warming being overwhelmingly negative by shunning their work and not allowing good work to be published in the mainstream scientific literature. Also, if one does disagree with their hypothesis of andropomorphic warming being significant, they go to ad hominem attacks in an organized fashion.
