I try not to be either optimistic or pessimistic. I try not to think about outcomes on that scale. My job, it seems to me, is to wake up every morning and figure out how to cause as much trouble for the fossil fuel industry as I can.

I've spent my life living in rural America, some of it in blue state Vermont, some of it in red state upstate New York. They're quite alike in many ways. And quite wonderful. It's important that even in an urbanized and suburbanized country, we continue to take rural America seriously. And the thing that makes Vermont in particular so special, and I hope this book captures some of it, is the basic underlying civility of its political life. That's rooted in the town meeting. Each of the towns in Vermont governs itself.

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.

In the States, I think, the syllogism goes like this: 'free markets solve all problems. Free markets aren't solving global warming, QED global warming is not a problem'. It's not a very good syllogism but it's emotionally comforting if you're in that world.

The most blatant examples are increased power and frequency in hurricanes and the increased depth and frequency of heat waves.

We have to transition to new technologies, making it more expensive to continue with the old and polluting technologies and cheaper to go to the clean ones.

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.
