I don't spend a huge amount of time fixated on climate denial because I don't think that their objections, though sometimes couched in science, are based in science. I think they're based in ideology. And I don't think there's anything you can do.

We've been in lots of places that I suppose, by Oxford standards, would be considered illiterate, but everyone's completely conversant with the idea that here is a number, and that number is above it, and that's too high. It's not a very complicated idea.

At least I sure hope it will - and I see good signs all the time, especially in things like the rise of local agriculture.

If we all used clotheslines, we could save 30 million tons of coal a year, or shut down 15 nuclear power plants. And you don't have to wait to start. Yours could be up by this afternoon. To be specific, buy 50 feet of clothesline and a $3 bag of clothespins and become a solar energy pioneer.

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.

When you are in a hole, stop digging!

There's a part of all of us whose impulse is to say, "Let's keep everything the same until I die and then you can do whatever you want afterward." And that's a difficult part.
