Oyster hatchery sows pearls of wisdom on climate change

In this photo taken Thursday, March 31, 2016, Jeff Auger inspects young oysters being grown on the Damariscotta River in Walpole, Maine. Mook Sea Farm and the University of New Hampshire are working together to monitor and adapt to changes in water chemistry caused by climate change. Greenhouse gas emissions blamed for global warming also are making the ocean more acidic, which can interfere with the ability of shellfish like oysters to develop their shells. (AP Photo/Holly Ramer)
