Ask Mr. Science.

Professor Myers offers Michele Bachmann (R-Ozone) a science lesson...

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.

If you need a lab assistant for that, Doc, just holler. Meanwhile, I'll follow your advice to point and laugh.
