Solar Geoengineering Deemed Feasible
November 25, 2018
New detailed evidence suggests that solar geoengineering—reducing global warming by injecting aerosols into the atmosphere to dim the effects of sunlight—would be possible and inexpensive, but the researchers say they made no judgment about whether the technology should be deployed. In that regard, a longtime researcher in the field recently argued in Issues that the time is right for launching a substantial international research program on solar geoengineering, and he proposed some basic principles that should guide the scientific community and government.
