The problem is that most people confuse weather with climate. They also do not understand that the weather will not be uniform with the whole planet. They think that GW means the whole earth will be hot, and everything will be a desert. However, they do not understand the topographical, geological, atmospheric, oceanic, and meteorological effects that GW will cause. It is that huge misunderstanding of atmospheric phenomena that the fossil fuel lobby exploits. So basically in their mind chaotic weather patterns such as the freak winter storm this last year? (or this year?) = GW false. When in fact the more chaotic the weather the more likely it is of a major climate shift.
