On September 16, 2013, the PBS “NewsHour” aired the first of a three-part series on “unexpected consequences of climate change,” according to the program’s Web site. Part One examined the consequences of increasing ocean acidification (caused by increased atmospheric carbon dioxide that dissolves into ocean waters) on Red King Crab and Snow Crab—two highly valuable commercial species—in Alaska’s Bering Sea. The seven-minute video is available online at http://www.pbs.org/newshour/bb/climate-change/july-dec13/arctic_09-16.html.
