An extremely effective instrument would be to put a price on carbon. It is only through the market that you can get a large enough and rapid enough response [to climate change]

Stop worrying about the lousy science, and how me the money already.

The IPCC doesn't do any research itself. We only develop our assessments on the basis of peer-reviewed literature.
