The climate is doing its usual tricks. There's nothing much really happening yet. We were supposed to be halfway toward a frying world now.

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

You mustn't take what I say as gospel because no one can second-guess the future.

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

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.

We'd never have got a chance to go outside and look at the earth if it hadn't been for space exploration and NASA.

Sadly, it's much easier to create a desert than a forest.
