This map provides an indication of the broad patterns of coral disease around the world. However, many coral reef locations are unexplored and not all observations of coral disease are reported.
The map depicts the frequency of future bleaching events in the 2030s and 2050s, as represented by the percentage of years in each decade where a NOAA Bleaching Alert Level 2 (i.e., severe thermal str
Coral reefs are classified by estimated present threat from local human activities, according to the Reefs at Risk integrated local threat index.
To evaluate change in pressure on coral reefs since 1998 (the year the first Reefs at Risk was published), Reefs at Risk Revisited undertook a separate comparative analysis using the 1998 modeling met
The assessment of the adaptive capacity of countries and territories to reef loss is based on economic resources, education, health, governance, access to markets, and agricultural resources.
Under the Reefs at Risk Revisited project, WRI and its partners have developed a new, detailed assessment of the status of and threats to the world’s coral reefs. This information is intended to raise awareness about the location and severity of threats to coral reefs.
Nine Caribbean sub-regions---Bahamian, Bermuda, Eastern Caribbean, Florida, Greater Antilles, Gulf of Mexico, Southern Caribbean, Southwestern Caribbean, and Western Caribbean.
When the four threats -- coastal development, sedimentation, marine-based pollution, and overfishing -- are integrated into the Reefs at Risk Threat Index, nearly two-thirds of the region's coral reef
Most reported observations of coral disease worldwide have been in the Caribbean.

Observations of coral bleaching in the Caribbean are widespread. Of the over 500 observations in recent decades, 24 were during the 1980s, over 350 during the 1990s, and over 100 since 2000.
