Solar geoengineering, or injecting aerosols into the atmosphere, could dramatically halt the effects of climate change. Harvard Professor of Applied Physics David Keith argues that solar geoengineering could be a radically effective way to halt climate change–and deserves serious, systematic research program by the US government.
David Keith has worked near the interface between climate science, energy technology, and public policy for 25 years. He took first prize in Canada’s national physics prize exam, won MIT’s prize for excellence in experimental physics, and was one of Time magazine’s Heroes of the Environment. David’s analytical work has ranged from the climatic impacts of large-scale wind power to an early critique of the prospects for hydrogen fuel. He is Professor of Applied Physics at the John A. Paulson School of Engineering and Applied Sciences and Professor of Public Policy at the Harvard Kennedy School.
