The latest Global Tipping Points Report suggests the world's coral reefs are at risk of mass dieback. More than 80 per cent of coral reefs worldwide have bleached in a marine heatwave in the past two years.
From 1 January 2023 to 20 April 2025, bleaching-level heat stress has impacted 83.7% of the world’s coral reef area.
Parts of the Great Barrier Reef have suffered the highest coral mortality on record, Australian research showed Tuesday, with scientists fearing the rest of it has suffered a similar fate.
The IUCN Red List of Threatened Species is warning that over 44% of reef-building coral species globally are at risk of extinction.
