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.

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 reality, climate change is actually the biggest thing thats going on every single day.

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

We can no longer imagine that we are part of something larger than ourselves - that is what all this boils down to.

We'd like to get the fossil fuel industry on the back foot for a while, having to deal with us.

The world hasn't ended, but the world as we know it has-even if we don't quite know it yet.
