I think that it is impossible to think of a threat to social justice greater than what we are doing to the earth's atmosphere at the moment.

We'd already lost the possibility of stopping global warming entirely. That hasn't been in the cards for a long time. The triumph of Trump probably means that we're not going to be able to stop it at the two-degree mark that the world had been aiming for. That's very bad news, mostly because the planet seems to be more sensitive than we thought to even small increases in temperature.

If we all used clotheslines, we could save 30 million tons of coal a year, or shut down 15 nuclear power plants. And you don't have to wait to start. Yours could be up by this afternoon. To be specific, buy 50 feet of clothesline and a $3 bag of clothespins and become a solar energy pioneer.

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.

By themselves, they are not enough; we also need to engage in political action.

It drives me crazy to see so much of this planet's life so casually endangered. The first steps are so easy (drive smaller cars, for instance) that it's very hard to understand why we haven't taken them. But I know that this is the issue our generation will be judged by.

Oil companies are radical because they're willing to alter the chemical composition of the atmosphere.
