Climate change is a huge problem, an almost insoluble problem, for two reasons. One is the habits of the West in terms of consumption. The other is the incredible iniquity between poor countries and rich countries on this planet.

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

When we work all over the planet, it's mostly poor and black and brown and young people, because that's mostly what the world [environmentalism] is.

Until it's understood to involve justice for those in poverty, a future for generations yet unborn, and a commitment to the rest of creation, it's unlikely we'll be able to overcome the status quo.

My goal was to have as many of the primary sources as I could made available for people to look at and understand. Climate change is probably the most important thing that's ever happened, and yet people's understanding of it and its history remains a little fuzzy.

For those of us who worry more about working people than about windfall profits for oil companies, it may net out. A better question is: what does it do to our economy if we manage to overheat the earth? This summer's drought provides a small taste.

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.
