David Keith is Gordon McKay Professor of Applied Physics at the Harvard School of Engineering and Applied Sciences, Professor of Public Policy at the Harvard Kennedy School, and founder of Carbon Engineering, a company developing technology to capture CO2 from ambient air to make carbon-neutral hydrocarbon fuels. Keith has worked near the interface between climate science, energy technology, and public policy for twenty-five years, and he is known for his work on the science, technology, and public policy of solar geoengineering. He is the author of A Case for Climate Engineering, which provides a clear and accessible overview of the costs and risks, and how climate engi-neering might fit into a larger program for managing climate change.
