Dr Gary Sharp, Scientific Director of the Center for Climate/Ocean Resource Study in Monterey Bay, California, makes a few good points regarding global warming and coral bleaching with particular reference to the Florida Keys in a recent article published by Tech Central Station titled, ‘Coral Bleaching: What (or Who) Dunnit?’:
1. Cold winters, not global warming, wiped out large areas of cold-sensitive corals in the Florida Keys in the late 1970s and early 1980s.
2. Coral reefs currently exists along a 6-7 degree temperature gradient so all the corals aren’t likely to die from a projected 2 degree celsius warming.
3. Sea surface temperatures are unlikely to increase by 2 degree celsius because the ocean responses to “excessive heating” through Deep Convection when the sea surface temperture exceeds about 27.5C.
