Full description Coral reef ecosystems are seriously threatened by changing conditions in the ocean. Although many factors are implicated, climate change has emerged as a dominant and rapidly growing threat. Even if the goals of the Paris Climate Agreement are achieved, 70-90% of coral reef areas are likely to cease to be suitable for coral growth by mid-century. Coral communities that survive will play a key role in the regeneration of reefs by mid-to-late century. The purpose of the 50 Reefs Project was to develop a long-term strategic plan for the conservation of coral reefs by identifying 50 large (500 km2) regions that are the least vulnerable to climate change and which are positioned to facilitate natural coral reef regeneration. These locations constitute important opportunities for novel conservation investments to secure less vulnerable yet well-connected coral reefs that may help to repopulate degraded areas after the climate has stabilized. The proposed strategy and actions should strengthen and expand existing conservation efforts for coral reefs as we face the long-term consequences of intensifying climate change.
