I think that some of it is electoral - helping candidates that are willing to take dramatic actions, not just to say a few words about how climate change might be a problem.

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.

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.

Here, there's more of a movement, it doesn't mean we're winning any more, but we're at least fighting.

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've been given a warning by science, and a wake-up call by nature; it is up to us now to heed them.

No one is strong enough  -  given the magnitude of the task, everyone has to step up their game.
