Part of situation: Climate change impacts on marine ecosystems (3 clusters)

IUCN assessment warns 96% of shallow-water coral reefs face critical risk

IUCN Red List coral reef collapse ocean warming climate change marine biodiversity

A new global assessment by the International Union for Conservation of Nature (IUCN) warns that 96% of the world’s shallow-water coral reef ecosystems are classified as “critically endangered.” The report, presented at the COP17 biodiversity summit in Yerevan, Armenia, indicates that these ecosystems face an extremely high risk of collapse by 2075.

The study analyzed 127 tropical and subtropical ecoregions, covering approximately 188,362 square kilometers across more than 80 countries and territories. Key threatened areas include Australia’s Great Barrier Reef, the Coral Triangle in the western Pacific and Southeast Asia, the Mesoamerican Barrier Reef System, and the Red Sea reefs.

Ocean warming and increasingly frequent marine heatwaves are identified as the primary drivers of this decline. The assessment utilized an IPCC intermediate climate scenario projecting 2.7 degrees of warming by the end of the century. While the risk is severe, researchers noted that some reefs have shown a capacity to recover from past bleaching events, suggesting that urgent conservation and climate action could still influence future resilience.
