We’ve heard Rep. Michele Bachmann (R-Minn.) rant about cap-and-trade in the past. Last week, on Earth Day, she attempted a scientific explanation of why carbon dioxide is not a problem. “Carbon dioxide is a natural byproduct of nature!” she said.

Carbon dioxide is natural. It occurs in Earth. It is a part of the regular lifecycle of Earth. In fact, life on planet Earth can’t even exist without carbon dioxide. So necessary is it to human life, to animal life, to plant life, to the oceans, to the vegetation that’s on the Earth, to the, to the fowl that — that flies in the air, we need to have carbon dioxide as part of the fundamental lifecycle of Earth.

It gets better: “There isn’t even one study that can be produced that shows that carbon dioxide is a harmful gas.”
