Film + Post-film discussion w/ director Ben Kalina
Solar geoengineering, otherwise known as sunlight reflection, is as controversial as it is fast and easy — but the more urgent the climate crisis becomes, the more scientists stand behind it as part of the solution. At the front of this movement is David Keith, the subject of this documentary, who has spent 30 years studying this technology. This film explores if and how this subset of climate tech could act as sunblock, and begs the question — is it enough? (dir. Ben Kalina, US, 2025, 108 min.)
