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.

Permafrost in the soil [is melting], in the boreal and arctic areas in the world, and, probably even more alarming in the last six or eight months, the data on what is happening to the ice shelves in Greenland and the west Antarctic has begun to cause people to radically reassess the earlier conviction that those ice shelves were stable on a kind of century-long time scale.

The latest computer modeling I've seen indicates that at mid-century, there might be 150 million people classified as "environmental refugees."

When you go to China and the developing world, people understand more clearly the dangers that are coming at them because they're living closer to the margin. They don't have any of the false sense of invulnerability that Americans have.
