Researchers Quietly Planned a Test to Dim Sunlight Over 3,900 Square Miles
California researchers planned a multimillion-dollar test of salt water-spraying equipment that could one day be used to dim the sun's rays — over a 3,900-square mile are off the west coasts of North America, Chile or south-central Africa. E&E News calls it part of a "secretive" initi...
E&E News calls it part of a "secretive" initiative backed by " wealthy philanthropists with ties to Wall Street and Silicon Valley" — and a piece of the "vast scope of research aimed at finding ways to counter the Earth's warming, work that has often occurred outside public view. The university and its partners — a solar geoengineering research advocacy group called SilverLining and the scientific nonprofit SRI International — didn't respond to detailed questions about the status of the larger cloud experiment. But SilverLining's executive director, Kelly Wanser, said in an email that the Marine Cloud Brightening Program aimed to "fill gaps in the information" needed to determine if the technologies are safe and effective.âIn the initial experiment, the researchers appeared to have disregarded past lessons about building community support for studies related to altering the climate, and instead kept their plans from the public and lawmakers until the testing was underway, some solar geoengineering experts told E&E News.
