Boehner: CO2 is a carcinogen

Teh confused, bewildered (hungover?) discussion on energy policy begins at around 2:00 minutes, and it gets funny at around 3:00 minutes:

My own transcript:
George, the idea that carbon dioxide is a carcinogen that is harmful to our environment is...is almost comical.
I believe the scientific community and John Boehner have finally found a point on which we all can agree. Next, we get a cute little science lesson from the House minority leader:
Every time we exhale carbon dioxide. Every cow in the world, uh, you know, when they do what they do, you got more carbon dioxide.
Yes, the carbon cycle is truly fascinating, but presumably the problem Boehner is referring to with cows involves methane. Of course we can always excuse politicians for not knowing much about science. It's when they start randomly making stuff up that one has to wonder whether their alarmist predictions about economic downfall cue to carbon dioxide regulation have any basis.

In that sense the Republican position as expressed here by John Boehner is even more illogical now than it was during the Bush years: they don't believe that CO2 is doing what science tells us it is doing, but they're strongly committed to 'doing something' about CO2 emissions. How stuck-in-the-past is that?
