Harvard scientists have launched the largest-ever research program into “solar geoengineering,” a controversial technique involving the injection of aerosols into the stratosphere with the goal of cooling the planet and reversing climate change.
Launched this weekend, Harvard’s Solar Geoengineering Research Program will investigate the safety of geoengineering as well as its environmental and political implications. Scientists specifically look into a technique of injecting specific particles into Earth’s upper atmosphere to create a barrier that reflects more sunlight away from the atmosphere.
“This would therefore offset some of the climate impacts from global warming by cooling down the global temperature of the earth,” said Elizabeth T. Burns, a research fellow at SEAS.
