The coral reef off southeast Florida is experiencing an unprecedented and potentially deadly level of bleaching this summer because of rising ocean temperatures caused by climate change, federal scientists said Thursday.
Some sites around the Florida Keys are being exposed to twice the amount of heat stress that causes corals to die, and earlier in the year than ever before, scientists from the National Oceanic and Atmospheric Administration said in a telephone news conference. They said the phenomenon is likely to affect the Caribbean very soon and a global bleaching event could be just around the corner.
The Florida Coral Reef is the world's third-largest, extending about 350 miles from the Dry Tortugas in the Gulf of Mexico to St. Lucie Inlet, about 115 miles north of Miami. The coral reef ecosystem sustains thousands of marine life species, protects against erosion and supports tourism based on scuba, snorkelling and fishing.
"Florida is just the tip of the iceberg," said Derek Manzello, coordinator of NOAA's Coral Reef Watch Program. "The scale of this event is very alarming. We are talking about thousands upon thousands of miles of coral reefs undergoing bleaching from severe heat stress." The world's oceans have been record-setting hot since April, with scientists citing climate change from the burning of coal, oil and natural gas along with a boost from El Nino, a natural warming of parts of the Pacific that changes weather worldwide and generally heats the planet. The bleaching happened rapidly as the water temperature rose in July.
