Burns, Lizzie, David Keith, Peter Irvine, and Joshua Horton. “Belfer Technology Factsheet Series: Solar Geoengineering” (2019).Abstract
Solar geoengineering refers to a set of emerging technologies that could alter the Earth’s radiative balance— perhaps through injecting aerosols into the stratosphere, where they would reflect a small fraction of sunlight back into space—reducing the amount of climate change caused by greenhouse gases. It could not replace reducing emissions (mitigation), coping with a changing climate (adaptation), or carbon dioxide removal (CDR). Yet it does have the potential to supplement these efforts, and it might provide reductions in climate risk that are unachievable by other means.
