I agree that some of our greatest scientists and greatest scientific discoveries have come from people who were ostracized by their peers ( Lets add Galileo, Copernicus, and Kepler to your list), but science has come a long way since those days. The "scientific process" itself was still in an infant stage, and there were a lot more phonies in the field. Science is a much more self-correcting/self-regulating field these days, not beholden to the influence of church and politics, except with select topics, of which global warming is probably the main one.
I agree, but I don't think all scientists are that impractical or political, except perhaps the loudest ones. After reading about this Muller, he seems to be able to separate the political BS from the straight science stuff. I can see how this would not make him all that popular with some of his peers.
Oh, I'm quite sure they would like nothing better than to "prove" that GB isn't real so that they can continue with their environmentally-ruinous ways. I am very wary of libertarians, because while I like that they are fairly tolerant in the social issues and fiscally sensible, they are often the worst when it comes to environmental policy. To a libertarian, the environment is always second to humanity. If it means destroying an ecosystem in order to provide jobs and profit, then so be it! What they fail to realize is that if we want to continue living on this planet any enjoy it's currently inhabitable and (mostly) beautiful state, we don't have a choice; we've got to put the environment first.
