Conservatism is a political philosophy that is, at its most fundamental, about resisting change.

So perhaps we shouldn’t be surprised that an outrageous and absurd line uttered about global warming in 2003—Oklahoma Senator James Inhofe’s assertion that it is the “greatest hoax ever perpetrated on the American people”—has not, nearly a decade later, been discredited on the right. Instead, this idea has persisted.

Indeed, the “hoax” charge was recently reiterated by Rick Santorum—who uttered it in Colorado on Monday en route to his three state primary triumph yesterday.

This raises at least two points for me that bear addressing:

This is a guest post by Bill Walker, originally published at Climate Central.

There’s a new ringleader of the skeptics' circus — otherwise known as the 2012 field of Republican presidential candidates.

Rick Santorum’s out-of-nowhere surge to a virtual tie for first place in the Iowa caucuses may not boost him to frontrunner status in next week’s New Hampshire primary and the states beyond. But in the contest to see which GOP candidate can be the biggest doubter of the science of climate change, Santorum is the unchallenged leader of the pack.

Santorum not only denies that manmade global warming is a growing concern, he denies its very existence. “There is no such thing as global warming,” he once said on Glenn Beck’s show, adding that it’s “patently absurd” to think a naturally occurring substance like CO2 – “a trace gas in the atmosphere, and the man-made part of that trace gas is itself a trace gas “ – is warming the planet. (Well, not if you understand the greenhouse effect.) He told Rush Limbaugh: “I’ve never … accepted the junk science behind that narrative.”

Rick Santorum was asked about climate change recently, while campaigning in New Hampshire. The video of his response, as well as the transcript, can be found here.

Suffice it to say that while Santorum sounds thoughtful and rational in his response, in fact he gravely misrepresents scientific knowledge and understanding.

Let's turn to the tape.

Santorum starts off well enough:

The question is on how do I get my policies with climate change science.

I get asked this question a lot, and you look at the data and you can see some change in the climate.

But then again, pick a point in history where you haven’t seen a change in the climate.

The climate does change.

The question is, what is causing the climate to change.

And I think most scientists, in fact, I assume all scientists would agree there are a variety of factors that cause the climate change.

I don’t think any scientist in the world would suggest there isn’t a variety of factors, and I think the vast majority of scientists would say there’s probably a hundred factors that cause the climate to change.

As Republican primary season schizophrenia continues, former Pennsylvania senator Rick Santorum is now in the spotlight, having very nearly beaten Mitt Romney in Iowa. So what do we people who care about science, and global warming in particular, know about Santorum?

Whoa boy.

None of the Republican candidates, with the possible exception of pro-science Tweeter Jon Huntsman, have distinguished themselves as science allies. Even sometime moderate Mitt Romney famously flip-flopped and cast doubt on human caused global warming; Rick Perry, meanwhile, thinks climate researchers are making it all up.

But Santorum? Arguably, his attacks on science surpass all of theirs.

The following post is from James Powell, author of The Inquisition of Climate Science. This is the first post in a 3-part series. It originally appeared at Columbia University Press.

In May 2011 the US National Academy of Sciences declared that “Climate change is occurring, is very likely caused by human activities, and poses significant risks for a broad range of human and natural systems. Each additional ton of greenhouse gases emitted commits us to further change and greater risks…. The environmental, economic, and humanitarian risks of climate change indicate a pressing need for substantial action to limit the magnitude of climate change and to prepare to adapt to its impacts.” One hundred other national and international scientific organizations agree with the NAS. How many disagreed? None. Zero. Zilch. As one scientist put it, “There’s a better scientific consensus on this than on any issue I know—except maybe Newton’s second law of dynamics.”

One organization that does dispute the NAS and the world consensus on global warming is the US House of Representatives. In April, the House took up a bill to remove the power of the Environmental Protection Agency to regulate greenhouse gases, opening a new front in the Republican War on Science (title of a great book by Chris Mooney). Rep Henry Waxman (D-CA) offered a countering amendment with language nearly identical to that of the Academy: “Congress accepts the scientific findings of the Environmental Protection Agency that climate change is occurring, is caused largely by human activities, and poses significant risks for public health and welfare.” The amendment failed 184-240, with one Republican voting in favor and three Democrats against.

The oil industry has put their astroturf and lobbying efforts into overdrive over the last few months, preparing for a bitter fight in the upcoming 2012 presidential election. In addition to their usual work of pushing for increased domestic oil production and the opening of federal lands for oil drilling, the industry is working around the clock to convince lawmakers to sign off on the Keystone XL Pipeline that would transport crude tar sand oil from Canada to Gulf Coast refineries.

ThinkProgress reporter Lee Fang has helped uncover some of the oil industry’s recent astroturf tactics at townhall meetings across the country. At a separate townhall event in Iowa, Republicans Rick Santorum and Herman Cain were asked questions by “activists” planted by the industry-funded group the Iowa Energy Forum.
