This isn't about good faith questioning of science, much as these naysayers pretend it is. It isn't about genuine skepticism, much as they want to believe it is. There is no moral imperative underlying their belief (or lack thereof). It's about unbridled hostility at the suggestion that we must all make shared sacrifices. It's about refusing to acknowledge that the environmental movement has been right to sound the alarm. It's about laziness. And greed. And irresponsibility. And colossal shortsightedness. Forget about the tragedy of the commons, this is the abject and gleeful refutation of common sense. Green-bashing exposes the rot at the core of modern conservatism.And he's right, of course. It's about greed, for the companies that are manufacturing lie-based doubt like it was coca-cola, sugar-water to increase their profit margin. But for the public at large, it's about partisanship.
And that's the problem. The conservative movement has become a quivering mass of resentment for most of its base (ridden by the greed-driven big-shots who hope to use it to grab more wealth for themselves).* If the democrats believe something, then they'll disbelieve it, even if the science is overwhelming and clear. (Some of this is conscious rejection of pointy-headed egg-heads; more of it, probably, is listening to deceitful propaganda on Fox &c.) They won't admit it's true because admitting its truth would require admitting the necessity of government intervention, the importance of science... and, ultimately, the rot of the conservative movement.
The fact that it's become a partisan issue is what will doom us. Because a huge minority of the most powerful country (and biggest greenhouse-gas-polluter) in the world -- a huge minority in a country where even a small minority can block meaningful political change -- would literally rather destroy the world than admit that liberals and scientists are right or that government is necessary.
They want it to be false, so their lives can be unchanged. And if that's not possible, they'll pile the world on a pyre and light a match.

* Note that this has now even been admitted by the Republican National Committee itself, who divide their base into "visceral" givers motivated by "reactionary" feelings and "fear", and "calculated" givers who are motivated by "ego" and "access". -- Admitted, of course, in a private document that they are now disavowing: if you're playing on peoples' fear and egos, you have to pretend you're not for it to work.
