From the beginning conservatives have been largely skeptical of the environmental movement. That skepticism has only increased as environmentalists more and more resemble socialists. Folks wonder if the environmentalists believe in their stated cause at all or if it is simply a front for their true cause.
Then along comes the idea that humans are causing global warming. The alleged cause: carbon dioxide, the natural result of just about every form of energy production we have (not to mention breathing). The prescribed cure: drastic cuts in the amount of CO2 produced, no matter the costs to industrialized nations. The penance: huge transfer payments to third-world countries.
Now, let's imagine that the data used to claim the earth is warming becomes suspect. Perhaps it turns out that numbers have been "adjusted" and the original data lost. Or that a semi-organized effort has been made to shut naysayers out of the debate.
So when a prominent global warming researcher admits the world may have been "warmer in medieval times than now" and "for the past 15 years there has been no 'statistically significant' warming," you might expect it to be big news.
Yeah, if you'd been living in a cave. Anything that runs contrary to the accepted global warming dogma is ignored by the majority of the media and by policy makers. Why give up a perfectly good crisis just because of data?
