Mostly I'm just writing books for the public, and so I try to describe for the public what the choices are, what they might have to expect in the future and so by warning people ahead of time maybe you have an effect.

There is no doubt that parts of the world are getting warmer, but the warming is not global.

There is nothing so big nor so crazy that one out of a million technological societies may not feel itself driven to do, provided it is physically possible.

The science window gives you a view of the world, and the religion window gives you a totally different view. You can't look at both of them at the same time, but they're both true.

If you start out with a tragic view of life, then anything since is just a bonus.

And somehow mother nature manages to create this incredible biosphere, to create this incredibly rich environment of animals and plants with this amazingly small amount of data.

Some things go better than you expected, other things go worse, so I'm... I think the only sensible thing is just to wait and see and what I'm doing when I'm writing books - I'm not doing science so much anymore.
