 Think for a minute about Newton and Einstein. Suppose that Einstein had stood up and said, I have worked very hard, and I have discovered that Newton got everything right, and I have nothing to add. Would anyone ever know who Einstein was? Scientists at some level have to have a little bit of ego. The job description is very clear. It is learn what nobody else knows. If you look at that and say, all I want to do is cheer for other people, you're probably not going into that field. If you go in that field, there's a little bit of ego to learn what nobody else knows, and we've all got it however well we tamp it down. The idea that we wouldn't want to be Einstein, if we could overturn global warming, if we could prove that CO2 was not a greenhouse gas, if we could prove that we can burn all we want and not worry about it. How exciting would that be? How many prizes? How many people would invite me out to give talks if I could prove that you didn't have to worry about this? Is there any possibility that tens of thousands of scientists, there isn't one of them that's got the ego to do that? It's absurd. It's absolutely unequivocally absurd. We're people, and we've got it in us the way people do. And the fact that nature pushes us to the reality that CO2 is a greenhouse gas, it's real. There's nothing we can do about it.
