We've abnegated the Kyoto treaty, we've instituted a voluntary program that's obviously not been working, we've taken every effort to excise references to global warming from official documents, to try to undermine international conferences that work on environmental issues, and on and on and on.

Do I think that people should in the best of all possible worlds have to go to jail for wanting the US government to pay attention to the warnings of scientists about climate change? Not really. I mean, in a rational world, if all the scientists said, "The worst thing that ever happened is about to happen and here's what you should do to stop it," you would expect any rational system to say, "Oh, sure, OK, let's do something about it." But that's not the world we live in. In the world we live in, you do need people willing to stand up, fight, march and sometimes go to jail.

If you look at the polling data, long before anyone had thought about Iraq, it was the [George W.] Bush Administration's decision in the first few weeks in its tenure in office to abnegate the Kyoto treaties that set our international perception into a nose-dive. People around the world looked on in amazement as the biggest part of the problem decided it wasn't going to make any effort to help with the solution.

Global warming is no longer a philosophical threat, no longer a future threat, no longer a threat at all. It's our reality.

A spiritual voice is urgently needed to underline the fact that global warming is already causing human anguish and mortality in our nation and abroad, and much more will occur in the future without rapid action.

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.

Stop thinking about global warming as a future threat and understand it instead as a present emergency, one that requires a far stronger policy response than we'd imagined.
