The report finds that the majority of the world's coral reefs are threatened by human activities and climate change, with projections that nearly all reefs will be threatened by 2050 if current trends continue. While 27% of reefs are in marine protected areas, only 6% are in effectively managed areas. The document emphasizes that reducing local pressures like overfishing and pollution is critical to increasing reef resilience against warming seas and ocean acidification.

The document reports that over 60% of the world's coral reefs are currently threatened by local human activities, with projections suggesting this could rise to nearly 100% by 2050 if left unchecked. It identifies key local stressors as overfishing, destructive fishing, coastal development, and pollution, alongside global threats like coral bleaching and ocean acidification caused by greenhouse gas emissions. The text emphasizes that countries such as the Philippines, Indonesia, Kiribati, Vanuatu, Tanzania, and Haiti are very highly vulnerable to reef loss due to high dependence on reef services and low adaptive capacity.
