It may sound like an idea out of a science fiction movie: spraying aerosols into the atmosphere to reflect sunlight and cool the Earth. But a new Nature Climate Change study by scientists at MIT, Harvard and Princeton says the process — called solar geoengineering — may be a cheap and effective way to reduce the impacts of global climate change. EAPS Cecil & Ida Green Professor of Atmospheric Science Kerry Emanuel discusses with WBUR how aerosols would be used to mitigate warming without globally worsening extreme temperatures or weather. A small fraction of locations may see exacerbated climate change impacts. Emanuel discusses the pros and cons of this measure.
