Presented by: Dr. Adina Paytan (UCSC Institute of Marine Sciences) November 21, 2013 Rising carbon dioxide in our atmosphere is changing the way the oceans work in ways never before seen in Earth's history. Scientists struggle to predict how our coral seas will change with the ocean's altered chemistry. How will these vital animals that provide a tropical home for thousands of other species, respond to new ocean conditions? Join Dr. Adina Paytan as she takes us to the natural laboratories of underwater springs called "ojos," in Caribbean Mexico's coral reef ecosystems, where several species of coral have already been living with acidic waters for thousands of years. Find out how the beautiful corals of the Mesoamerican Barrier Reef might respond to a transformed climate, and what we can do to protect them.
