This photo provided by the University of Miami Coral Reef Futures Lab, shows fire coral and staghorn corals with bleaching, tissue loss, and recent mortality on Thursday, July 20, 2023, in the North Dry Rocks Reef off the coast of Key Largo, Fla. Some Florida Keys corals are losing their color weeks earlier in the summer than has been documented before, meaning they are under stress and their health is potentially endangered, federal scientists said.
