Excerpt: In Alameda [CA], scientists are embarking on a novel attempt to cool the Earth — by spraying salt into clouds. The work, known as marine cloud brightening, is controversial and is just one method of geoengineering — which describes interventions meant to slow Earth’s warming. But proponents say the technology may be needed to mitigate climate change. To brighten clouds, researchers spray microscopic sea salt into the air over the ocean to boost clouds’ reflectivity. This means less sunlight is absorbed, leading to a planetary cooling effect. ...Scientists hypothesize that by manually increasing the number of particles in the atmosphere, clouds will reflect more sunlight back to space, causing Earth to cool. ...Scientists like Russell say that before more drastic solutions are deployed, the focus should be on reining in greenhouse gas emissions and making further investments in solar and wind power. “Emitting particles to offset global warming is not the smartest idea … but it may be better than doing nothing,” Russell said. “Given the point we’re at with warming and climate change, we feel it’s important to know what our options are.”....
