Coral reefs have been framed as ecosystems in irreversible decline, threatened by rising ocean temperatures, bleaching events, and ecological collapse. If global temperatures rise to 1.5°C above pre-industrial levels, up to 90% of tropical coral reefs may vanish by 2050. According to allafrica.com, the study 50 Reefs Plus identified approximately 165,000 square kilometres of coral reefs with the strongest potential to survive and recover from climate change — if protected. The research drew on more than 45,000 coral surveys and decades of climate and ocean data to produce what its authors described as a global map of coral refugia: the places most likely to persist as the planet warms. According to bluesky, researchers have identified far more climate-resilient reefs than previously recognized. The narrative about coral reefs is more complex and hopeful than the doom narrative.
