I think [George W.] Bush has done nothing right about global warming.

In fact, corporations are the infants of our society - they know very little except how to grow (though they're very good at that), and they howl when you set limits. Socializing them is the work of politics. It's about time we took it up again.

Delhi is locked in a complete choking smog at the moment - they've had to close schools in one of the world's biggest cities. They have their own reasons for needing to get off fossil fuels fast.

The idea that China and India will just abandon climate action is not true, because they're doing it for more reasons than we are.

After a lifetime of nature shows and magazine photos, we arrive at the woods conditioned to expect splendor - surprised when the parking lot does not contain a snarl of animals attractively mating and killing each other.

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.

In my own faith tradition, these questions have been very important. It has always been easiest for me to apprehend God in the natural world. I love to go to church, but when I really want to feel the presence of the divine I'm more likely to head up into the mountains.
