The flight deck of a decommissioned World War II-era aircraft carrier docked at Alameda has recently begun launching something other than airplanes: microscopic droplets of salt water that scientists hope will help counteract the effects of climate change.

A team of atmospheric scientists from the University of Washington has teamed up with Silicon Valley-based Stanford Research Institute, an independent nonprofit research facility, and SilverLining, a nonprofit focused on near-term climate risks, to study whether adding plumes of salt water to a cloud will make it more reflective and stop excess heat from reaching the Earth’s surface.
