This week, host Daniel Raimi talks with Harvard University Professor David Keith about solar geoengineering. Keith describes the variety of ways that solar geoengineering could work; some of its risks at local, regional, and global scales; recent small-scale experiments; and what might be needed to deploy a larger-scale research program. Raimi and Keith also discuss public policies related to potential deployment technologies, including the substantial issues surrounding governance and geopolitics.
