I'm not a climate scientist, so I guess I can't answer, and so what if it is, the models are making predictions, then there are observations, what's wrong with challenging the science, like I said before, this is not a religion, in science, there is a THEORY, the theory is tested, then retested, then adjusted, and tested again. All I'm saying is, get very nervous when people say things like "there is no debate", or "the science is settled", especially when they're from the government, and even more so, when there are billion in funding on the line. It's also very telling when anyone that poses questions/challenges is disparaged and called names. That is not science, that is religion.
