Belfer Center: Solar Geoengineering: Taking a Hard Look

„“Fear of solar geoengineering is entirely healthy,” Harvard Professor of Public Policy David Keith wrote in a Guardian op-ed in 2017. “Its mere prospect might be hyped by fossil fuel interests to thwart emissions cuts. It could be used by one or a few nations in a way that’s harmful to many. There might be some yet undiscovered risk making the technology much less effective in reality than the largely positive story told by computer models.” Yet,” he added, “that healthy fear can distort discussion in unhealthy ways.”“
