To just add to what my colleague said, how could 1,200 scientists from around the world, who have 6,000 other scientists looking over their shoulders, possibly be part of a conspiracy to falsify data and to announce to politicians, and to the entire world for that matter, that a catastrophe is imminent? Scientists just aren’t like that, they just aren’t in the same category of human or animals as are the deniers, the skeptics. The skeptics are people who have to be part of a crusade, or part of a religion, or something, and who are governed by instinct, whereas scientists study data and have no choice in the answers they give.
