It’s been called climate change’s ‘evil twin.’ As carbon dioxide builds up in the atmosphere, it dissolves in the ocean, creating carbonic acid that is disrupting the pH balance of the ocean. Voila, ocean acidificatoin. It’s estimated that the ocean is now 30% more acidic than it was 150 years ago. That could spell trouble for animals like corals and clams that build skeletons and shells out of calcium carbonate, because acidic conditions limit the amount of calcium carbonate in the water. It’s a problem that the National Academy of Science says has received too little attention.
Scott Doney – an ocean acidification researcher at Woods Hole Oceanographic Institution – has said that New England is the most vulnerable region in the country when it comes to the impacts of ocean acidification. At a conference in early 2009, he said that ocean acidification could start affecting shellfish within 20 years.
