PZ goes after MB

My esteemed colleague at the University of Minnesota-Morris, PZ Myers, goes after US Representative Michelle Bachman:

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.
