The white haze that hangs over many major cities could become a familiar sight everywhere if the world decides to try geoengineering to create a cooler planet.
Scientists have long suspected that one oft-discussed geoengineering technique — shooting tiny sulfate particles into the upper atmosphere to deflect sunlight — could turn the blue sky white
Cleaning Up Air Pollution May Strengthen Global Warming
New research is helping quantify just how big that effect might be
