Sagan was right, but in my view your application of his phrase is baffling upside down. The claims regarding the impact of AWG are extraordinarily extraordinary: millions will die of famine, storms will ravage the earth, sea levels will drown existing coast lines, and most all of this will happen in this century. Given all these extraordinary claims, you look not to evidence at all, but to consensus.I think it was Carl Sagan ( I could be wrong) that said that extraordinary claims require extraordinary evidence. For example if you told me that a mouse was in the next room I would require little evidence to believe you. However, if you said that a moon man was in the next room I would require a ton of evidence to believe you. When you claim that every scientific organization of national or international standing is part of a global conspiracy, I require a lot of evidence.
