If you spend a lot of time with activists, as I have, they're just ordinary people who instead of Netflix are getting together in church basements and making posters or making phone calls doing organizing work. It really is about finding a community of other people.

Catastrophic damage from climate-driven extreme weather is now an annual reality. The cost of not dealing with it will be much greater than if we try to pre-empt some of those disaster cleanups by actually investing in the shift now.

We're dealing with a crisis of inequality, of joblessness, of underemployment.

Film 'This Changes Everything' is not a sad story. It's not a slit-your-wrists climate film. It's a story about people who are making change happen.

I think that kind of urgency is what makes this stage of the climate movement really different from what it was even a few years ago when it was much more of the professionalized NGOs lobbying behind closed doors and maybe having a march now and then.

I've always kind of hated films about climate change.

Once you feel the desire to engage, think about what you're good at and what you can contribute. It's about breaking down the idea that there are activists and ordinary people.
