PUBLIC DOMAIN As the consequences of global warming become more dire, a research team led by Stony Brook University Professor Jessica Gurevitch is examining the ecological impacts of using a form of geoengineering to mitigate the effects of global warming. Geoengineering, also known as climate intervention, is a set of proposed methods and technologies designed to alleviate the impacts of environmental change caused by global warming while society works to reduce emissions. One theoretical approach of geoengineering is called stratospheric aerosol intervention (SAI) which involves injecting gaseous precursors of reflective sulfate aerosols into the stratosphere in an attempt to reflect some of the sunlight back into space and in turn, cooling the Earth’s surface.
