Romney and SantorumRomney & Santorum, both bad news for the environment.Photos: WEBN TV’s Political Pulse & IowaPolitics.comRick Santorum, who surged at the last minute to give Mitt Romney a real run for his money in Tuesday’s Iowa caucuses, is less green than his rival, and decidedly nuttier when it comes to climate change. But let’s not split hairs here. Both men will staunchly defend fossil fuels, and neither is likely to do much of anything to fight global warming.

Mitt Romney has expressed qualified concern about climate change over the years, and then vacillated about how much of it is human-caused and whether we should try to do anything about it.

No wobbling of that sort from Santorum — he’s an out-and-out denier. “There is no such thing as global warming,” he told a smiling Glenn Beck on Fox News in June 2011. That same month, he told Rush Limbaugh that climate change is a liberal conspiracy: “It’s just an excuse for more government control of your life and I’ve never been for any scheme or even accepted the junk science behind the whole narrative.”
