Previously, proponents of geoengineering solutions to global warming have suggested that reflective aerosol particles could be sprayed into the upper atmosphere to achieve the same sunlight-reflecting effect as aerosol pollution. Opponents argue that this idea seems risky. I would have thought that what has been observed in the Pacific and Indian oceans as a result of pollution shows, to the contrary, how effective upper-atmosphere aerosols can be in reducing incoming radiation. Surely this is an idea worth pursuing.
