I think it's very important to invite and encourage people to talk about climate change who have a lay understanding. In general, there is a lot of confusion among climate activists about the role of science, that scientists should be social and political leaders of this movement.

While the American people have the impression that scientists are hard at work figuring out this complex matter of climate change, it's not actually that complicated.

I argue that I don't think it's a moral position to say that civilization is going to collapse, and that's okay. Because that would cause the deaths of billions of people. It's certainly not something I'm willing to accept.

Climate change is the sine qua non of continued civilization. We either solve this, or it's lights out. Turning into a collective like that is so much more aligned with how humans live and think and change.

My grandmother is a Holocaust survivor. Some heroes of mine have long been the Jewish Partisans, these young people who just went into the woods with whatever guns and bombs and what not they could get their hands on, and just would fight Nazis, and try to help people escape.

Psychologically speaking, the rational, healthy response to climate change is to say to oneself, "What can I do about this?" But that question is often answered through individual action.
