Richard Muller, Phd: I didn’t know whether global warming was real, whether it was completely bogus or maybe it was twice as bad as people said. So my daughter and I … decided we would set up a non-profit organization to study climate change ourselves. We brought in some really good people … who shared the same doubts that I had. So we wound up doing an enormous effort, completely rebuilding a program to use historic temperature records … and in the end, we got a nice curve, a curve that showed the temperature. And it was rising.
Now, we’d never expected to address the question of what caused it … we went back all the way to 1753 … I was flabbergasted: not only was global warming real, and roughly consistent with what the previous groups had said, but the match to carbon dioxide, and the fact that solar variability was not responsible enabled us to rule out the primary alternative theory … in fact, we can rule out every scientific theory other than the greenhouse gas theory.
Now there are some people who … say “there’s something else going on”. And I say “what’s the prediction you make?” — “Oh, I don’t know, it’s random.” And that’s not what we call a scientific theory. If you say, “Well, it’s something else and I don’t know what it is” my answer is “Something else that just happens, by accident, to perfectly match the carbon dioxide increase. Are you serious?”
