When world-renowned researcher David Keith and for-profit start-up Make Sunsets push into the taboo territory of solar-radiation modification, they spark a global question with life-or-death stakes: How far are we willing to go to cool the planet?  Part thriller, part wake-up call, Plan C for Civilization reveals the hidden world of climate tech — and asks whether we can afford to ignore one of the most controversial ideas on Earth.

Join us for this provocative and timely documentary followed by a discussion with the director Ben Kalina and Stony Brook University Political Science Professor Reuben Kline.
