Yeah, and if the climate scientists are as wrong as nutritionists were about fats [1][2]...then what? We destroy the world economy for the wrong reason? In ANY complex system, there are trade offs for every choice. And would you starve a billion people to save the planet? Would you quadruple oil prices to cut emissions...hurting the poorest in the process? The point of free speech is that we DEBATE things like this so we can TRY to arrive at the best answer, knowing damn well we still might have to TRY AGAIN if and when we fail.
