At the moment, the 4 percent of us in this country produce a quarter of the world's carbon dioxide - once you look at maps of rising sea levels and spreading mosquitoes, you realize that we've probably never figured out a way to hate our neighbors around the world much more effectively.

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.

We spend probably more of our time than we should, just because it's close to home, worrying about the West. But it's equally important to figure out how we're going to free up the resources to let the developing world leapfrog the fossil fuel age. That's at least as mathematically important, and at least as morally crucial.

We use the web to help people organize in the flesh, and then we take the images of those events and put them back on the web to make them add up to more than the sum of their parts.

We spend a lot of time playing defence against bad things. So, in the US, one of the focusses has been this huge Keystone Pipeline project, another has been the coal ports on the Pacific Ocean.

So far the earth has warmed about a degree Fahrenheit globally averaged. That doesn't seem like an enormous amount but it's unlike what we would have expected twenty years ago.

When you are in a hole, stop digging!
