I think the world on the other side of fossil fuel is more local - the logic of sun and wind is diffuse and spread out, not concentrated like the logic of coal and oil.

A price on carbon sufficient to keep 80% of current reserves underground, rebated directly to citizens.

All the science in the last few years, or almost all of it, really serves to show that the [climate] effects are larger and more rapid than we had thought even a decade ago.

I did very much like [Barack] Obama's attack on fossil fuel subsidies for fossil fuel companies. We asked for that in demonstrations and petitions, and now we'll try to push it forward.

Often when I'm on TV, they'll ask what are the three most important things for people to do. I know they want me to say that people should change their light bulbs. I say the number one thing is to organize politically; number two, do some political organizing; number three, get together with your neighbors and organize; and then if you have energy left over from all of that, change the light bulb.

We are altering the most basic forces of the planet's surface - the content of the sunlight, the temperature and aridity - and that brings out the most powerful questions about who is in charge. If you wanted to give a name to this theological problem, I think you could say that we are engaged in decreation.

Especially in recent years, the more and more we understand what we are doing, the more we have the science to tell us what we're doing, the fact that we continue to do it without taking steps to address it strikes me as, among many other things, irreverent in an extreme.
