In yesterday’s New York Times:
Scientists have understood ocean acidification for a long time. But what they are learning now is how quickly it is increasing, in step with increases in atmospheric carbon dioxide. New studies show that if carbon dioxide emissions continue at current rates, shells and corals could begin to dissolve — especially in the southern oceans — within 30 years. Observations from many places, including the Caribbean Sea and the Pacific Ocean, suggest that ocean acidification is proceeding much faster than anyone had thought.
