I do a certain amount of work in religious communities on these issues. It's not the central focus of my work but it is certainly an area where I have worked a lot. It has gotten much better over the years, especially over the last couple years. There wasn't a religious environmental movement 15 years ago, but there is now - in the Catholic community, the Jewish community, the mainline Protestant community, and in the Evangelical community.

In the end, climate change is a math problem.

what you do every day is what forms your mind and precious few of us can or would spend most days outdoors.

[Political actions] has to happen on the local and state level; we have to convince our cities to join the growing number of more than 200 American cities who have signed on to the mayor's climate campaign.

I also think we need unconventional political action, and I increasingly think that there is a need for people of faith to be able to do the kind of things that people of faith did 40 years ago in the heat of the civil rights revolution. This is a moral issue of every bit as much importance requiring every bit as much sacrifice, courage, and energy as that crisis did.

Environmentalism, I'd always been told, was just rich white people.

Policies that engage us again in the international fight for real climate protection.
