There is basically no one not on the payroll of Exxon Mobil or coal companies who any longer contend that this is not something to worry about.

We had other currencies that we could find work in - the currencies of movements: passion, spirit, creativity.

You think OWS is radical? You think 350.org was radical for helping organize mass civil disobedience in D.C. in August against the Keystone Pipeline? We're not radical. Radicals work for oil companies. The CEO of Exxon gets up every morning and goes to work changing the chemical composition of the atmosphere. No one has ever done anything as radical as that, not in all of human history.

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.

It now appears that the fracturing of that ice is happening much more quickly than people previously thought, apparently at a slow melt.

All the things that we've done as a species have had a limited scope. We're talking about melting the ice caps, raising the level of the seas dramatically, changing the distribution of every other species on Earth, perhaps wiping out one-third or half of them. The changes at work are geologic in scale. The level of change required to deal with it is enormous, too. It will require change in every country. It will require a degree of global cooperation that we haven't seen before.

The world is on fire, and I'm doing my best to help steer the firetruck.
