The Senate's most prominent climate change skeptic, Sen. Jim Inhofe (R-Okla.), called in to Mike Huckabee's radio show on Monday to discuss conspiracy theories on global warming and the Obama administration's plans to deal with it.

In the segment, both Inhofe and Huckabee accuse the Obama administration and Organizing for Action -- the nonprofit created out of the Obama campaign to stump for the president's agenda -- of violating federal law in their push to combat climate change. Inhofe has called for an investigation into whether the administration is coordinating with OFA on political activities in violation of the Hatch Act. He claims that because the Environmental Protection Agency is working on climate rules and OFA is working to promote climate action, there must be some manner of illegal interaction.

Last week OFA delivered "Climate Denier Awards" in the shape of unicorns to members of Congress. Inhofe was on the list.

"We go through these 30-year cycles." (The planet doesn't warm on its own; something has to force it, and scientists have found that the current warming is being driven by the build-up of human-produced greenhouse gases.) The senator's appearance on Huckabee's show was mostly a chance for him to rehash bad science on global warming, including claims such as:

"We went into a leveling-out period about eight years ago." (Nope. Sorry.)

"You have to have CO2. It's a form of fertilizer to grow things. It's actually sought after in many cases." (There is such a thing as too much of a good thing.)

"When I was in college, all the literature at that time from the scientific community said that we were going to freeze to death." (No, it didn't.) Huckabee also threw in a few of his own theories:

"The volcano that erupted over in Northern Europe actually poured more CO2 into the air in that single act of nature than all of humans have in something like the past 100 years." (Even when it was erupting, the European aviation industry's emissions alone dwarfed the volcano's daily emissions.)
