Episode 4.4: Geoengineering

In this episode, we delve into the world of climate intervention and geoengineering, specifically focusing on solar geoengineering, also known as solar radiation modification (SRM). Host Ryan Katz-Rosene as he explores the complexities of this technology with two leading experts. First, we hear from Dr. Pete Irvine, as he breaks down the science behind SRM, particularly stratospheric aerosol injection (SAI), and discusses the potential benefits and risks, and addresses the current state of research and the ongoing debate surrounding field experiments. Then, we shift gears to hear from Dr. Aarti Gupta, who provides a crucial counterpoint, highlighting the voices of many in the academic community and beyond who are deeply concerned about the potential deployment of solar geoengineering. She emphasizes the growing opposition from the Global South, the disproportionate impact concerning vulnerable nations and Indigenous communities, and the governance challenges that this technology presents.
