With climate change, of course there are things to grieve. I certainly grieved that the vision that I had for my life, that I would be a clinical psychologist and write books and have a family, that that was not going to happen, because if the world is collapsing around you, it just doesn't seem that appealing anymore.

I used to be a lot more afraid of climate change. Now I spend my time working, planning, trying to move forward.

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.

There are a lot of reasons people don't talk about climate change. One of them has to do with the language of science, and people feeling not competent about this issue.

Taking fear seriously is not easy. A lot of people's response to fear is "Don't worry so much, it's crazy." But some things absolutely deserve our fear, and climate change is first among them.

It is rarely comfortable to talk about climate change. Bringing something difficult up, it feels like somehow by mentioning this I'm kind of causing it, I'm hurting these people. But you're not hurting these people; climate change is hurting these people. You're telling them they're being hurt.

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.
