Academy Award–winning filmmaker James Cameron will premiere a short film, Not Reality TV, Wednesday night at the Democratic National Convention in Philadelphia. And while Leonardo DiCaprio is noticeably absent from this Cameron film, disaster is certainly not: The subject of the short — which features scenes from the upcoming season of Years of Living Dangerously — is climate change.

“We made this film to show the reality of climate change — how it’s directly affecting millions of people each day,” Cameron said in a press release. “America just experienced its hottest year ever, rapidly rising sea levels are threatening coastal communities and causing migrations across the globe, and extreme weather events like wildfires and hurricanes continue to spiral out of control as temperatures rise. As I’ve said before, to save our planet we need to mobilize like we did during World War II — the threat to our country and children is that severe.”

A World War II-like mobilization to deal with the effects of climate change is, for the first time in history, written into the Democratic Party’s platform. The platform pledges that in the first 100 days of the Clinton administration, the president will hold a summit of engineers, climate scientists, policy experts, activists, and indigenous communities to devise a plan to solve the climate change crisis.
