We'll never get there if we let the climate crisis bloom unchecked, so for the moment the key is to organize, organize, organize!

I'm probably the wrong person to ask. My partner in much of this work [climate movement], who really came up with the divestment campaign with me, Naomi Klein, I think has written powerfully about this.

I'm guessing the most efficient way would be to transfer an awful lot of technology, but also direct aid to deal with climate emergencies already underway. Hillary [Clinton] has already said $100 billion a year would be appropriate.

There hadn't really been a climate movement, per se. I think everyone spent twenty years thinking that if we just keep pointing out that the world is on the edge of the greatest crisis by far it's ever come to, then our leaders will do something about it. And it turned out that was wrong. They weren't going to do anything about it.

Those of us in the west have figured out a lot of ways to damage the lives of poor people in this country and around the world over the years.

My house is covered in solar panels, I'm a great believer in all this - we all should be doing this.

When you go to China and the developing world, people understand more clearly the dangers that are coming at them because they're living closer to the margin. They don't have any of the false sense of invulnerability that Americans have. People from developing countries also feel that it's their right, if you're talking in terms of justice, to use fossil fuels like we did for a hundred years to get rich. It's hard for them to give up that vision.
