At least I sure hope it will - and I see good signs all the time, especially in things like the rise of local agriculture.

We'd won the argument 15 years before, we were just losing the fight. And so it became clear to some of us that we would need to organise to fight, that we weren't going to win.

If it's wrong to wreck the planet, it's wrong to profit from the wreckage.

I do a certain amount of work in religious communities on these issues. It's not the central focus of my work but it is certainly an area where I have worked a lot. It has gotten much better over the years, especially over the last couple years. There wasn't a religious environmental movement 15 years ago, but there is now - in the Catholic community, the Jewish community, the mainline Protestant community, and in the Evangelical community.

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.

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.

We have built a greenhouse, a human greenhouse, where once there bloomed a sweet and wild garden.
