Reflecting on Solar Geoengineering, with David Keith

| May 12, 2020

In this episode of Resources Radio, host Daniel Raimi talks with David Keith, a physics and public policy professor at Harvard University and one of the world's leading experts on solar geoengineering. Keith outlines prominent examples of solar geoengineering technologies in development—from ambitious ideas, such as sending aerosols to the stratosphere, to more operational solutions, like painting roofs white to reflect more sunlight into space. An advocate for research on solar geoengineering, Keith discusses how coalitions among like-minded nations and clearer guidance from policymakers could expand deployment of promising technologies.
