But it hasn’t yet tackled Bachmann’s Earth Day floor speech about the Obama administration’s plan to regulate carbon dioxide emissions. Biologist P.Z. Myers quickly debunks some of those claims, including the biggie — that because carbon dioxide is naturally occurring it’s “harmless”:

She claims that not one study has ever been produced to show that CO₂ is harmful, and she goes further to claim that CO₂ is a harmless gas. We could correct that in just a few minutes: give me a large tank of CO₂ and a small room containing Michele Bachmann, and we’ll give her a personal experience.

Update: Bachmann is using the DCCC site to fundraise, according to MPR. She sent out an email that reads, in part:

“The Democrats are gunning for me because I refuse to shrink from a fight. With your help, I can keep fighting for your freedom, for your pocketbook, and for all that the Constitution has secured for the American people for generations.”
