Climate change is the single biggest thing that humans have ever done on this planet. The one thing that needs to be bigger is our movement to stop 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.

TV, and the culture it anchors, masks and drowns out the subtle and vital information contact with the real world once provided. There are lessons, enormous lessons, lessons that may be crucial to the planet's persistence as a green and diverse place and also to the happiness of it's inhabitants-that nature teaches and TV can't.

I think that some of it is electoral - helping candidates that are willing to take dramatic actions, not just to say a few words about how climate change might be a problem.

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.

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.

Winning slowly is another way of losing. Americans are screwing up our health care system again right now. That's going to cause grave trouble for people over the next five, 10 years. There are going to be lots of people who die, lots of people who are sick. It's going to be horrible. But 10 years from now it will not be harder to solve the problem because you ignored it for those 10 years. With climate change, that's not true. As each year passes, we move past certain physical tipping points that make it impossible to recover large parts of the world that we have known.
