Australia's Great Barrier Reef is hundreds of miles of tiny creatures -- corals that are exquisitely sensitive to changes in ocean temperatures. In recent years, seas overheated by less than two degrees have killed an estimated one fourth of this magnificent world wonder. One of the world's great living wonders is dying fast. Can the Great Barrier Reef be revived? We ask Mark Eakin, coordinator of the National Oceanic and Atmospheric Administration's Coral Reef Watch Program.
