The U.S. House Committee on Science and Technology has held a series of hearings over the past year on climate geoengineering. The recent testimony of Dr. Philip Rasch of the Pacific Northwest National Laboratory would be a very good class reading for a geoengineering module because it explores a number of important issues, including the potential cost of such schemes, the contours of research and deployment, potential time lags in impacts, and a good explanation of the mechanisms of the two primary solar radiation management, stratospheric sulfate aerosol and tropospheric cloud seeding.
