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. The proposal calls for what’s known as “solar geoengineering”: cooling the planet by deflecting sunlight that would otherwise strike the planet. Concentrations of greenhouse gases are at.
