Without climate action, nearly all coral reefs risk disappearing

A new report presented by the IUCN at a biodiversity summit in Yerevan, Armenia, warns that nearly all coral reefs could face collapse by 2075 without urgent climate action. Evaluating 127 reef systems spanning over 180,000 square kilometers, the study highlights that approximately one-quarter of these ecosystems are already severely threatened. Rising ocean temperatures are identified as the primary driver behind this projected decline, which puts iconic structures like the Great Barrier Reef and the Coral Triangle at significant risk. The findings underscore the critical role reefs play, as they support over 25 percent of all marine life.

Despite these dire predictions, researchers maintain that coral reefs possess inherent resilience and recovery is possible. Experts emphasize that urgent reductions in greenhouse gas emissions must be paired with local environmental protections. Authorities are urged to prioritize sustainable fishing practices and the maintenance of clean coastal waters to protect reefs, as well as associated mangroves and seagrasses. However, meeting these conservation goals remains a major challenge, particularly as international progress toward global biodiversity targets appears to be falling behind schedule.
