[More crazy talk from Carnegie Institute’s Ken Caldiera… Anthony] Washington, DC– Major volcanic eruptions spew ash particles into the atmosphere, which reflect some of the Sun’s radiation back into space and cool the planet. But could this effect be intentionally recreated to fight climate change? A new paper in Geophysical Research Letters investigates. Solar geoengineering is a…
