In this Climate Chat episode, we interview climate scientist David Keith, Professor of Geophysical Science at the University of Chicago where he leads the Climate Systems Engineering program. David previously ran a similar program at Harvard. Dr. Keith founded Carbon Engineering, a company that captures CO2 from the atmosphere. We will discuss the feasibility, safety, scalability, and political ramifications of climate interventions such as carbon capture and Sunlight Reflection Methods (SRM), a.k.a., solar-geoengineering.
