Before geoengineering, some fundamental chemistry

Research led by Joseph S. Francisco of the School of Arts & Sciences examines the chemistry of a proposal to curb climate change’s effects—creating a sunshade in the upper atmosphere made of sulfuric acid—and finds that there’s more work to do to successfully pull off such a feat.
