Why Bill Gates Is Funding Solar Geoengineering Research

Bill Gates is backing the first high-altitude experiment of one radical approach called solar geoengineering. It's meant to mimic the effects of a giant volcanic eruption. Thousands of planes would fly at high altitudes, spraying millions of tons of particles around the planet to create a massive chemical cloud that would cool the surface. "Modeling studies have found that it could reduce the intensity of heat waves, for instance, apparently it could reduce the rate of sea level rise. It could reduce the intensity of tropical storms," said Andy Parker, project director at the Solar Radiation Management Governance Initiative.
