Our Warming Oceans: Biosphere to Bahamas

In the Arizona desert, scientists study a small ocean at Biosphere II facility, where researchers measure sea changes under controlled conditions. But the real ocean is uncontrolled and vast. David journeys to the Bahamas to join researchers in caves and in reefs who are making startling findings about changes in climate and their effects on our oceans.
