John Boehner is an idiot, too.

So, John Boehner (R-Ohio) goes on ABC's This Week, and says the following in response to a question about Republican plans to combat global warming:

"George, the idea that carbon dioxide is a carcinogen that is harmful to our environment is almost comical. Every time we exhale, we exhale carbon dioxide. Every cow in the world, you know, when they do what they do, you’ve got more carbon dioxide. And so I think it’s clear…"

Oh, it's clear, all right.  Clear that you're an empty-headed moron who slept through all his high school science classes.

1. It's not that carbon dioxide is a carcinogen, it's that it's a greenhouse gas.  Greenhouse gases trap heat and raise the average temperature of the earth.  Has nothing whatsoever to do with cancer.
2. I assume you're referring to cows farting, in which case you might be referring to methane, rather than carbon dioxide, but in either case, it's a complete non-sequitur.  Animal life produces carbon dioxide, therefore it plays no part in global warming?

Boehner is an idiot.
