Ocean acidification

A video from testimony given by Jane Lubchenco, Administrator of the National Oceanic and Atmospheric Administration, at a hearing on 2 December on the State of Climate Science. Total time for the two videos is 15 minutes. Not only does Lubchenco explain the concepts very well, she demonstrates them with two simple experiments. In addition, a video showing the increase in acidification projected through 2100 under a "business as usual scenario" is very, very sobering.
