Ocean Acidification Could
Amplify Global Warming, Study Says
The increasing acidification of the world’s oceans caused by rising concentrations of atmospheric carbon dioxide not only poses a threat to marine creatures, but also could lead to an intensification of planetary warming,
according to a new study. A team of U.S., British, and German researchers conducted experiments in seawater enclosures, known as mesocosms
, showing that the increasing acidification of the ocean leads to a drop in production of an important sulfur compound, dimethylsulphide, or DMS. Marine emissions of DMS are the largest natural source of atmospheric sulfur,
and those sulfur aerosols play an important role in reflecting the sun’s energy back into space and cooling the planet. Reporting in the journal Nature Climate Change
, the scientists found that when they created acidic conditions in the seawater enclosures that match pH levels expected in 2100, emissions of DMS fell by roughly 18 percent. The scientists said that their study was the first to prove the link between rising ocean acidification and the potential decrease in planet-cooling sulfur dioxide aerosols.
