The International Union for Conservation of Nature (IUCN) released a global assessment warning that 96% of shallow-water coral reefs face an extremely high risk of collapse by 2075. The report, announced during the U.N. biodiversity conference in Albania, identifies climate change as the primary threat to these ecosystems.
Key Takeaways
The International Union for Conservation of Nature (IUCN) warns that 96% of shallow-water coral reefs face collapse risk by 2075 due to climate change and human activities. The assessment highlights the critical threat to ecosystems like the Great Barrier Reef, Coral Triangle, Mesoamerican Barrier Reef System, and Red Sea coral reefs.
- IUCN classifies 96% of global coral reef systems as critically endangered
- Climate change is identified as the primary driver of coral reef decline worldwide
- Famous reef systems like Great Barrier Reef are at highest threat level
- Coral collapse would impact marine biodiversity, coastal protection, and tourism

The assessment examined 127 tropical and subtropical ecoregions covering 72,726 square miles (188,362 square kilometers) of coral reefs globally. It found that most famous reef systems - including Australia's Great Barrier Reef, the Coral Triangle in Southeast Asia, the Mesoamerican Barrier Reef System, and Red Sea coral reefs - are critically endangered.
Mishal Gudka, scientific lead of the IUCN assessment, emphasized that while the prognosis is dire, it should serve as a wake-up call. 'Coral reefs have shown a remarkable ability to bounce back from devastating bleaching events,' he said. The report suggests that pockets of resilient coral reefs could survive with immediate and sustained conservation efforts.
The IUCN assessment follows other recent studies highlighting the severe threats to coral ecosystems. A study published in Nature found that nearly 44% of reef-building coral species face elevated extinction risk due to climate change, while a survey from last year revealed that harmful bleaching has affected 84% of ocean's reefs - the most intense recorded.
