I guess there is a reason why coral grows in the tropics.
SUMMIT COUNTY — Amid all the concern over the impacts of rising sea temperatures to coral reefs, University of Georgia researchers have found that cold water is just as bad.
An extended cold snap in Florida in January and February 2010 killed nearly all the coral in a 200- to 300-year-old reef that had survived other extreme events, including the 1998 El Niño bleaching that damaged coral reefs across widespread regions of the world’s oceans.
During the 2010 cold snap, water temperatures at inshore reefs in the upper Florida Keys dropped below 54 degrees and remained below 64 for two weeks. The University of Georgia team had planned to sample corals at Admiral Reef, an inshore reef off Key Largo. When they arrived, they discovered that the reef, once abundant in hard and soft corals, was essentially dead.
