More than 60 experts, including several past guests on The Sweaty Penguin, made headlines last week for signing a letter that encourages the international community to adopt a non-use agreement for solar geoengineering—a set of technologies that aim to reflect or block out a fraction of the sunlight hitting the Earth in order to artificially cool the climate. In this episode, learn what solar geoengineering could accomplish at its best, what some of solar geoengineering’s (arguably insurmountable) challenges would be, and what comes next for this technology. With special guest Dr. Elizabeth Chalecki, Associate Professor of Political Science at the University of Nebraska Omaha.
