We'd already lost the possibility of stopping global warming entirely. That hasn't been in the cards for a long time. The triumph of Trump probably means that we're not going to be able to stop it at the two-degree mark that the world had been aiming for. That's very bad news, mostly because the planet seems to be more sensitive than we thought to even small increases in temperature.

I think fracking for gas will reduce the incentive to turn to renewables, and I think it will do a lot of other damage across the countryside.

If we continue to think of ourselves mostly as consumers, it's going to be very hard to bring our environmental troubles under control. But it's also going to be very hard to live the rounded and joyful lives that could be ours. This is a subversive volume in all the best ways!

The movers and shakers on our planet, aren't the billionaires and generals, they are the incredible numbers of people around the world filled with love for neighbor and for the earth who are resisting, remaking, restoring, renewing and revitalising.

I don't know how to make people who absolutely have to be obsessed with paying a week's energy bills... obsessed with climate change... It's very hard.

Sometimes, I, anyway, get tired of playing defence, and like to play offence.

In the scientific community, the debate is over, for all intents and purposes, about whether or not the planet is heating and who is causing it. In fact, it's more or less been over since 1995.
