A Filmmaker Focuses on Climate and Democracy

The Athens Democracy Forum last week featured an array of speakers from countries worldwide: politicians, leaders of nonprofits, youths dedicated to promoting democracy. Michael P. Nash was the only filmmaker to speak.

Mr. Nash, who resides in Nashville and Los Angeles, is behind more than a dozen documentaries and psychological thrillers. His most well-known work is “Climate Refugees,” a documentary that debuted at the 2010 Sundance Film Festival and portrays the stories of people from 48 countries who were affected by climate change.

Mr. Nash’s other notable films include “Fuel” (2017), which focuses on alternative energy, and “Saving the Roar” (2021), an inspirational sports documentary about Penn State University’s football culture.

Mr. Nash is directing and producing “Chasing Truth,” a documentary examining whether artificial intelligence can solve environmental issues such as climate change and food security. The film is a collaboration with the actor Leonardo DiCaprio and his father, George DiCaprio, who are executive producers. It is expected to be released in 2026.

George DiCaprio said he and his son got to know Mr. Nash more than a decade ago, at a screening of “Climate Refugees” at their home. “It was clear that we all shared a passion for addressing the world’s most pressing issues, and now, more than ever, that commitment has deepened,” he said in an email.

After the forum, Mr. Nash was interviewed by email and phone about his interest in democracy advocacy; the connection between climate change and democracy; and what he had learned in Athens. The conversation has been edited and condensed.
