World's oceans close to becoming too acidic to sustain marine life, report says

A new report by the Potsdam Institute for Climate Impact Research details how a crucial threshold for ocean acidification could soon become the seventh factor breached – out of of nine – considered critical for the planet's ability to regulate life-sustaining natural systems. The growing acidification of the planet's oceans is due to ever-increasing emissions of carbon dioxide released by burning fossil fuels, which the oceans then absorb.
