Yeah, you should see some of the nutty right-wing conspiracy theories out there about how the government is making up global warming & the fact that we need to take care of the environment so they can seize land, relocate everyone and kill off "80% of the population".
I think it gives some folks some weird comfort to believe that all-powerful humans are ruining their lives rather than taking responsibility for being part of the problem.
It also feeds into people's sense of entitlement (like Dick Cheney said "the American way of life is non-negotiable") and climate change is probably the scariest looming uncertainty of our times. So it's natural people would deny it, making up conspiracies if necessary.
Climate change also smacks right-wing ideology into the "failed human enterprises" bin. Humans, en masse, in a consumer driven society, are clearly not acting in their own best interests (in the long term), this is now undeniable. Unless you biodiversity is plummeting (on land & at sea), the climate is changing, etc.
Really, it makes perfect sense hard-righters & scared young libertarian fanboys would be terrified to admit that human consumer decisions, en masse, might devastate the planet (and by "the planet" I mean the planet's ability to support human existence). Even without global warming evidence suggests that your average human is fairly poor at making wise, long-term decisions (especially in our current society that encourages us to live for the moment & "treat ourselves"). The massive amount of consumer debt we face (not throwing stones, I owe a bit myself) is evidence alone of this (plus people who bought houses they couldn't afford, the obesity epidemic, etc. etc.).
It's time to stop pretending that any one man can be an island & that you're no more responsible for your community or the Earth itself than you are to the rocks on Mars. Libertarianism is, at it's core, a hands off, "not my problem", "que sera sera", philosophy. Mainstream right-wingism (as it exists today in America) is... well, I don't even know, the worst of libertarianism, the worst of corporate socialism (which I commend libertarians for not supporting, if a libertarian became prez & eliminated meat & dairy subsidies, that alone would massive decrease American carbon emissions drastically), and the worst of religiosity
* (and arbitrary & foolish moral absolutes imposed on their fellows - no woman's right to have sovereignty over her body, gays can't marry, or even have sex [sodomy] with each other in some states, teaching Creationism in science class, etc.). Also, fundamentalists Christians (including Bush supposedly) believe in end times anyway, so why would global warming matter. According to them Yahweh, not Gaia, decides who gets to live or die & they see respect for (God forbid worship of) the Earth as almost as bad as Golden Calf worship.
"He who loves his life loses it; and he who hates his life in this world shall keep it to life eternal." (John 12:25) WIth an attitude like that why would any self-respecting (er, self-hating?) Christian care about the environment? Life in heaven is what matters. Screw the Earth & Al Gore's phony ploys to get us to trade in our SUV (I wonder if one of those could fit thru the eye of a needle

), the Lord said dominate the Earth by golly & that's what I'm going to do, it's all going to end when Christ returns anyway!
* Keep in mind I said "the worst of religiosity", not that religious sentiment is, in & of itself, bad. So please don't take that as a flame.
