We need a more authoritative world...What's the alternative to democracy? There isn't one. But even the best democracies agree that when a major war approaches, democracy must be put on hold for the time being. I have a feeling that climate change may be an issue as severe as war. It may be necessary to put democracy on hold for a while.

Humans are too stupid to prevent climate change from radically impacting on our lives over the coming decades.

What we have lived through, the 20th century, has been like a great party. Adults now have had the best time humanity has ever had. Now the party is over and the Earth is reckoning up.

I'm a scientist, not a theologian. I don't know if there is a God or not. Religion requires certainty.

All the modelling we do shows that the climate is poised on the jump up to a new hot state. It is accelerating so fast that you could say that we are already in it.

Nature favors those organisms which leave the environment in better shape for their progeny to survive.

I'm not a pessimist, even though I do think awful things are going to happen.
