Oceans could slurp up carbon dioxide to fight global warming

Researchers in Massachusetts and Pennsylvania are proposing a new method for reducing global warming that involves building a series of water treatment plants that enhance the ability of the ocean to absorb carbon dioxide from the atmosphere. About 100 such plants — which essentially use the ocean as “a giant carbon dioxide collector” — could cause a 15 percent reduction in emissions over many years, they say. About 700 plants could offset all CO2 emissions. Their study is scheduled to appear in the Dec. 15 issue of ACS’ Environmental Science & Technology.
