96 percent of global coral reefs are threatened with extinction due to climate change

A study by the IUCN reveals that 96% of tropical and subtropical coral reefs are at risk of extinction due to climate change. These reefs, sensitive to heat, could disappear by 2075 as marine heatwaves increase. Key locations affected include the Great Barrier Reef and the Coral Triangle. Coral reefs support a quarter of marine life and cover 188,362 square kilometers. The research is based on a climate scenario predicting a 2.7°C rise in global temperatures by the century's end, with current projections suggesting a potential 2.8°C increase by 2100.
