Of course the fact that what you refer to as science has been disproven has nothing to do with it. The fact that it was all about politics and social engineering means nothing.One of the reasons that the skeptics are such a force is that the science has moved to the point that there is little need for the scientists to justify their position. They have moved on to another phase, that of how to help mitigate the problems. The skeptics, on the other hand have not consolidated their positions and are still trying to pick at the science. They are a very vocal tiny majority that feel they must bend the ears of the politicians and the media and anyone else who will listen to get them to support their position. They must depend upon politics and the vested interests to bolster their ideals.
So far they have done a pretty good job of undermining the science through politics. They have capitalized upon the sharp division between political ideologies by equating the science with a movement by the government of taking away our freedoms. There is little support of this other than propagandized emotional extravaganza. It harkens back to the McCarthy era and the Communist scare that gripped the nation. There is little solid evidence to support such a position. One thing is clear, time will settle the question. The problem is that this may result in irreversible damage to the planet.
The fact is that the science behind AGW failed. The theory fell flat. Time is on the skeptics side and now people are starting to shift. To believe that not only warming is over but an ice age approaches. Of course they may be right, just not in out life time.
