I think we're doing pretty well. It's clear the media, of course, always gives you the bad news.

Science is my territory, but science fiction is the landscape of my dreams.

The average ground temperature of the Earth is impossible to measure since most of the Earth is ocean...So this average ground temperature is a fiction.

The thing that makes me most optimistic is China and India - both of them doing well.

It's us that's really amazing. As far as I can see, our concentration of different abilities in one species - there's nothing I can see that in this Darwinian evolution that could've done that. So it seems to be a miracle of some sort.

For any speculation which does not at first glance look crazy, there is no hope.
