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.

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.

Climate change has been associated so much with a peaceful mentality - obviously peace and love are good, but we need to think about climate as a threat to survival.

Online petitions are built around getting as many signatures as possible. But the experience of taking them and forgetting about them degrades the importance.

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

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.

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.
