A UNEP article published on 4 September summarized a new status report from the Global Coral Reef Monitoring Network. The report surveyed nearly 37,000 coral sites in more than 120 countries, comparing cover in 2020–2024 with the 1980–2009 historical average, and estimated that at least 9.5% of hard corals had disappeared.

UNEP described the estimate as conservative and said losses were uneven across regions, with signs of recovery in parts of South Asia and the western Indian Ocean. The report identifies marine heatwaves, pollution, overfishing and coastal development among pressures on reefs.
