It's much to the credit of the rest of the world that they have gone ahead and tried to do the Kyoto accords on their own. It makes it unbelievably difficult to do that, for a variety of economic and regulatory reasons, without the participation of the biggest energy user in the world.

Very few people on earth ever get to say: 'I am doing, right now, the most important thing I could possibly be doing.' If you'll join this fight that's what you'll get to say

The roof of my house is covered in solar panels. When Im home, Im a pretty green fellow.

I think the best way is to keep stressing, that, as we build out a new energy system, one of the best things about it, if we do it right, will be that it will be more local, more democratic, more distributed, and, in the long run, much more economically sensible.

Probably more than anything else, the place that we really see the effects of the power of even the relatively mild temperature increases so far is in the melting of everything frozen on the planet.

But the truth is that we could win every other fight that we face and if we lose the climate fight, the other victories will be pyrrhic. I don't think even people who are worried about climate change quite understand the scale and speed with which we're now shifting the planet.

A world where one tenth of the population gets to be extremely wealthy, and six tenths very poor, is not, in the long run, a stable place.
