When you are in a hole, stop digging!

The irony is that one of the things people want to solve climate change is more market - more price on carbon so that markets have something to chew on when they think about climate change instead of the complete monopoly, the absurdity of allowing these guys to own the sky for free - socialise all of the costs and privatise all of the profits.

Without a movement pressing for change, there's little hope. We've got to work the political system to make this happen fast. The physics and chemistry are daunting. The resources on the other side are very large.

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

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.

I think we need to go straight at the fossil fuel industry.

To me, it's more important to take the 60-70% of people who really understand that there's a problem [of climate change] and get some percentage of them active than to try and stamp out the last embers of pre-scientific thought.
