Award-winning filmmaker Ben Kalina (Shored Up, Can We Cool the Planet?) returns with Plan C for Civilization, a riveting new documentary that confronts one of the most controversial ideas in climate science: solar geoengineering. The film will make its world premiere at DOC NYC on Thursday, November 13 (6:30 p.m.) and Saturday, November 15 (1:00 p.m.) at Village East by Angelika, with an online screening available from November 14 to 30.

In Plan C for Civilization, physicist David Keith explores whether reflecting sunlight back into space could cool the planet and buy humanity time against climate catastrophe. But his early experiments spark fierce global debate, inspiring rogue start-ups like Make Sunsets, whose DIY launches raise urgent questions about science, ethics, and control in a warming world.

Kalina captures this unfolding tension across continents, examining the promise and peril of manipulating Earth’s atmosphere as climate solutions falter. “If we value the ecosystems and humanity of this planet,” Kalina says, “how could we ignore any tool with so much power to cool the planet, quickly?”

Produced by Mangrove Media, the film continues Kalina’s exploration of humanity’s uneasy relationship with nature, following his acclaimed documentaries on climate and coastal resilience.
