I read his statement that Global Warming science is not certain, in spite of world wide agreement among many thousands of scientists that man is the principal cause for rapid warming now, because 1200 “scientists” disagree. Peterson went so far as to say that the fact global warming science is conclusive is a lie. He failed to vet the 1200. Only one was a supposed climate scientist, the rest were from other fields not qualified in climate science. I was shocked and very disappointed in his position. As a geophysicist, I have studied climate science thoroughly for 40 years. Peterson is taking a purely political, anti-science position.
