Reflecting on Solar Geoengineering, with David Keith

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.
