Scott Pruitt denies basic science that we've understood for over a century

The current head of the US Environmental Protection Agency Scott Pruitt does not believe or understand long-known principles of climate science and basic physics. Recently he claimed on CNBC that carbon dioxide is not a primary contributor to global warming:

I think that measuring with precision human activity on the climate is something very challenging to do, and there's tremendous disagreement about the degree of impact. So, no, I would not agree that's a primary contributor to the global warming that we see. But we don't know that yet. We need to continue the debate and continue the review and the analysis.
