A voluntary simplification of life-styles is not beyond our abilities, but it is probably outside our desires.

Ice in the West Antarctic and over Greenland, i.e., ice that's over a rock at the moment, that will raise the level of the sea as it slides into the ocean, putting at risk everyone and everything that lives on the coasts, and that includes an enormous percentage of the world's people.

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.

The ability to write compelling emails may be the single most useful talent an organizer can possess.

If you were running a solar company you may be okay - you may be able to keep growing. The question for physics is: Can you grow fast enough to begin to catch up with the damage?

Other thing we need to understand is that the financial power of the fossil fuel industry has so far prevented even any minor progress. They have a sweetheart deal unlike any other business on Earth: they're allowed to dispose of their waste for free, to use the atmosphere as an open sewer. And they will do all they can to defend that special privilege.

Speaking for me, I think the odds of bankrupting Exxon are pretty small, but I think the odds of politically bankrupting them are higher. I think if we can use this as a vehicle to get out the analysis that these guys have 3-5 times as much carbon in the ground as the most conservative government thinks would be safe to burn, then that politically stigmatises them, makes them into the rogue industry that they are.
