Researchers report remote sensing data that suggests emissions of dimethylsufide, which promotes aerosol formation, from the Arctic have increased by around 13 gigagrams of sulfur per decade since 1998, a 33% increase per decade, which is explained by decreased Arctic ice cover; the authors suggest that the total loss of ice in the Arctic in the summer may result in a 2.4-fold increase in emissions compared with current rates.
