Dave Roberts confronts the new Pew poll showing a decline in the number of Americas who believe in global warming:

It should be noted, of course, that 57% ain’t bad, given the public’s generally low level of scientific knowledge. About 79% of people know the earth revolves around the sun rather than vice versa, while 80% believe prayer accelerates healing. Some 75% believe in angels but just 39% believe in evolution. Public opinion on matters of science is of great interest for a great many reasons, but it is a poor guide for public policy. Everyone deserves to have their voice heard on how we might best respond to what’s happening, but what’s happening is happening and we can’t change it by not acknowledging it.
