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.

everyone knows, at some level, that the sharp line between "good weather" and "bad weather" is a fiction, that we need rain as surely as we need sun.

We, all of us in the First World, have participated in something of a binge, a half century of unbelievable prosperity and ease. We may have had some intuition that it was a binge and the earth couldn't support it, but aside from the easy things (biodegradable detergent, slightly smaller cars) we didn't do much. We didn't turn our lives around to prevent it. Our sadness is almost an aesthetic response - appropriate because we have marred a great, mad, profligate work of art, taken a hammer to the most perfectly proportioned of sculptures.

In the scientific community, the debate is over, for all intents and purposes, about whether or not the planet is heating and who is causing it. In fact, it's more or less been over since 1995.

I think the best way is to keep stressing, that, as we build out a new energy system, one of the best things about it, if we do it right, will be that it will be more local, more democratic, more distributed, and, in the long run, much more economically sensible.

The earth is a museum of divine intent.

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