Kelly Wanser heads Silver Lining, a nonprofit  “dedicated to ensuring that society has information and options to address near-term climate risk.” In this episode, Wanser explains why she prefers to use the term “climate intervention” instead of “geoengineering,” how an “aerosol parasol” placed in the stratosphere might help reduce the danger of catastrophic climate change, and the many technical and political challenges facing climate intervention efforts.
