Global warming
I am not a scientist, but I respect those in the profession and would defer to the general consensus among scientists who specialize on a particular topic if I have any questions on the matter. In this case, the question is whether or not global warming, or climate change, is taking place. The consensus among climatalogists and meteorologists is yes it is happening. Not everyone in these fields agree, but that is the general consensus. Yet among the conservatives here in America, it has become almost a point of religious doctrine that not only is global warming not happening, but that it is a hoax. If a Republican politician veers from this attitude to recognize scientific findings he is not likely to go far in the party. The most recent case in this respect would seem to be Jon Huntsman.
