The fact that the climate is getting warmer doesn't scare me at all. There's no reason why one should be scared.

It has become part of the accepted wisdom to say that the twentieth century was the century of physics and the twenty-first century will be the century of biology.

I am saying that all predictions concerning climate are highly uncertain.

I don't think of myself predicting things. I'm expressing possibilities. Things that could happen. To a large extent it's a question of how badly people want them to.

I like people who are working on practical things and who are working in teams. It's not so important to get the glory. It's much more important to get something that works. It's a better way to live.
