Significant technological advances in satellite technology and atmospheric measurements have greatly enhanced the understanding of methane concentrations and emissions. The dynamic ways in which those advancements are allowing researchers to monitor methane emissions down to the source level was the focus of discussion Thursday (November 17) at a COP-27 side event co-hosted by the Harvard Project on Climate Agreements, the Enel Foundation, and the government of Mexico.

Paul Joskow, the Elizabeth and James Killian Professor of Economics emeritus at MIT and former President and CEO of the Alfred P. Sloan Foundation in New York City, shared his thoughts on U.S. regulatory economics and climate change policy in the latest episode of “Environmental Insights: Discussions on Policy and Practice from the Harvard Environmental Economics Program.”

Joseph Aldy and Richard Zeckhauser advocate for urgently getting serious about solar geoengineering as a realistic response to climate change that could significantly curb consequences to human well-being.

Daniel Esty, the Hillhouse Professor of Environmental Law and Policy at Yale University and author of the new book, Values at Work: Sustainable Investing and ESG Reporting, expressed his optimism for the prospects of climate policy in the Biden Administration 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.

Professor Joseph Aldy says the incoming U.S. administration can breathe new life into global efforts against climate change, but faces daunting political and economic obstacles.

Joseph Aldy and Richard Zeckhauser write that the world needs a new strategy to fight climate change aggressively and effectively.

After reviewing emission mitigation’s poor performance and low-probability of delivering on long-term climate goals, the authors evaluate a three-pronged strategy for mitigating climate change risks: adding adaptation and amelioration — through solar radiation management (SRM) — to the emission mitigation approach.  They conclude by assessing the value of an iterative act-learn-act policy framework that engages all three prongs for limiting climate-change damages.

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.

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, discussed his groundbreaking research and policy work in the field of solar geoengineering in the newest episode of “Environmental Insights: Discussions on Policy and Practice from the Harvard Environmental Economics Program.” Listen to the interview here.
