SRM Is Coming Faster Than You Think — Ben Kalina on 15 Years Filming Climate’s Most Controversial Idea
Sunlight reflection has spent decades as an idea scientists batted around at academic conferences. Now venture-backed companies are racing to build deployment systems, state legislatures are passing bans on weather modification research, and the public still mostly thinks the contrails overhead are a government plot. Ben Kalina has been pointing a camera at this entire evolution for fifteen years. Plan C for Civilization, his documentary on the field’s emergence as serious research, is the closest thing we have to a real historical record of how this is unfolding. We talked about what changed Ben’s mind about the timeline, why average audiences leave his film more curious not less, the strange dynamics of venture capital entering a space that runs on trust, and what of the Stardust Solutions optics problem can and cannot be engineered away.
Ben Kalina is a documentary filmmaker and a professor at Drexel University. His new film Plan C for Civilization follows the emergence of solar geoengineering research, centered on David Keith, the SCoPEx experiment at Harvard, and the late entrance of Make Sunsets. The film is currently in festival distribution and screening tour. More at plancforcivilization.com.

Notable quotes
“This stuff is coming at us, solar geo, much, much faster than most people realize. There’s probably some major decisions that are going to start getting made in the next few years. And the public has no clue. And if they do, they think they’re talking about chemtrails.” — Ben Kalina
“When you start talking about making the planet more reflective, that’s a ‘could possibly go wrong’ thought. That’s a classic ‘why the hell would we do that.’” — Ben Kalina
“We could have the science down to a T with solar geoengineering. You could have isotopic markers on the particles you’re putting up there, and there’s still going to be a big piece of this that is just trust.” — Ben Kalina
“Nobody in this field is a climate denier. They all come to this kind of as a career last resort, after having sort of figured out that there’s nothing else where they can contribute.” — Ben Kalina
“Stardust Solutions, in this moment, being an Israeli company of former nuclear scientists funded by Silicon Valley tech billionaires whose stated goal is to change the planet’s temperature, and accidentally, by the way, name themselves after the empire’s plan to build the Death Star.” — Ben Kalina
