The field of solar geoengineering revolves around the idea of cooling the globe via the injection of aerosols to reflect sunlight or to thin clouds. One such strategy, stratospheric aerosol injection (SAI), aims to mimic the effects of a volcanic eruption. Volcanoes spew sulfur dioxide into the stratosphere, which then reflects light back into space, cooling Earth for potentially a year or longer, as documented in previous eruptions.
