Diver with coral. At least 500 million people rely on reefs for food, coastal protection, and their livelihoods. Climate change is the biggest threat to the world's coral reefs, causing mass bleaching, among other things. Studies examining coral communities that already persist under naturally-occurring extreme and marginal physicochemical conditions have therefore become increasingly popular to advance ecosystem scale predictions of future reef form and function, although no single site provides a perfect analog to future reefs. Florida's coral reef extends from Martin County on the Atlantic Coast of Florida through the Keys to the Dry Tortugas in the Gulf of Mexico. NOAA scientists declared the onset of a global coral reef bleaching event impacting coral reefs in every ocean basin, and projected the bleaching will only intensify in 2016.

Coral reefs in the western Atlantic and Caribbean are deteriorating primarily from disease outbreaks, increasing seawater temperatures, and stress due to land-based sources of pollutants including sediments associated with land use and dredging. But corals are also severely threatened by rapidly worsening environmental conditions.
