Climate change is a huge problem, an almost insoluble problem, for two reasons. One is the habits of the West in terms of consumption. The other is the incredible iniquity between poor countries and rich countries on this planet.

We can either save the planet from catastrophic warming, or protect fossil fuel CEOs. Not both. Do the math(s)

For the first time in 150 years, the USDA reported there were more farms in America, not fewer. That has to make you happy.

The fact that Washington has been a complete logjam for anything for the last six years has got to change because we need to have federal policy that really allows us to move quickly and nimbly.

I try not to be either optimistic or pessimistic. I try not to think about outcomes on that scale. My job, it seems to me, is to wake up every morning and figure out how to cause as much trouble for the fossil fuel industry as I can.

Our weird problem is an abundance of resources and a shortage of hard economic reasons not to use them.

My house is covered in solar panels, I'm a great believer in all this - we all should be doing this.
