A New Generation of Climate Scientists Warm Up to Solar Geoengineering
Fed up with a lack of action on climate change, some students are researching dimming the sun despite the pushback from other scientists.

Yashas Raj and Jake Chapman are hunkered down in a basement laboratory at the University of Cambridge’s Department of Engineering—tinkering with a handheld nozzle they hope will one day be capable of shooting trillions of microscopic water droplets into the sky every second to brighten clouds over the Arctic Ocean. Boosting cloud reflectivity by adding the mist, they say, would cut the amount of sunlight reaching the water’s surface and slow the melting of Arctic sea ice.
