Social movements throughout history take place in people's minds. If we got 5,000 Americans who were talking about climate change to their neighbors and to their coworkers, and talking about this pledge, that would change the political and social landscape so much more than if 5,000 people got arrested for protesting a pipeline.

By looking the other way on climate change we facilitate a collective denial, and we do it for each other.

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.

What we accomplished during World War Two is just amazing. We turned our country upside down. African Americans were demanding to be given combat missions. 10% of Americans moved in order to relocate for a war job. We as a country accomplished this heroic, nearly miraculous thing, and we have this legacy of policies and agency - how did they do it? How did they fund it? How did they organize it? It is actually an example that we can borrow from very productively to guide us.

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.
