Science, Technology, and Public Policy

Professors David Keith and Joseph Aldy and their co-authors say deeper social science research could contribute to policy decisions on this tool to address climate change.

John Holdren, former director of the White House Office of Science and Technology Policy, expressed his optimism in the Biden Administration’s approach to climate policy in the latest episode of “Environmental Insights: Discussions on Policy and Practice from the Harvard Environmental Economics Program,” a podcast produced by the Harvard Environmental Economics Program.

Daniel Schrag argues that in order to reestablish the United States as a serious partner in addressing global climate change, the president must make good on the original standards of the Paris Agreement.

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.

Professor Robert Stavins interviews David Keith, Gordon McKay Professor of Applied Physics at the Harvard John A. Paulson School of Engineering and Applied Sciences, and Professor of Public Policy at Harvard Kennedy School, considered one of the world's leading scholars on solar geoengineering.

As numerous studies have made strikingly clear, climate change is increasing much more rapidly than anticipated and its negative impacts are becoming more and more visible around the world. From the escalating extremity of weather events, severe droughts and wildfires, to melting glaciers, rising sea levels, and disastrous floods, climate change is already harming humans and our ecosystems in a myriad of ways.
