In an ideal world, cutting carbon emissions would be enough to stop global warming. But after dithering for decades, the world needs a back-up plan. Kelly Wanser is the leader of a group called SilverLining that works to promote research into what it calls “solar climate intervention.” Also called “solar geoengineering,” this approach involves putting particles into clouds that reflect back the sun, directly cooling the earth. It’s a novel and potentially hazardous policy — but one that Wanser and other experts argue could hold a lot of promise as the world braces for catastrophic climate impacts. Wanser and Vox’s Dylan Matthews discuss how solar climate intervention works, how it could be implemented, and where it fits in with the goal of cutting emissions.
