Test of Planet-Cooling Scheme Could Start in 2022

Cars That Think

Up there, 10 to 50 kilometers above the Earth’s surface, ozone molecules absorb the sun’s ultraviolet light, protecting life far below. Even less is understood about the potential risks to people and the environment—could the particles deplete the ozone layer, for example, or significantly alter the weather?
