There is a tendency at every important but difficult crossroad to pretend that it's not really there.

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.

At least I sure hope it will - and I see good signs all the time, especially in things like the rise of local agriculture.

Stop thinking about global warming as a future threat and understand it instead as a present emergency, one that requires a far stronger policy response than we'd imagined.

In the end, climate change is a math problem.

I think we need to go straight at the fossil fuel industry.

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.
