“The Great Barrier Reef has experienced its greatest annual loss of live coral across most of its expanse in four decades of record-keeping, Australian authorities say. But due to increasing coral cover since 2017, the coral deaths — caused mainly by bleaching last year associated with climate change — have left the area of living coral across the iconic reef system close to its long-term average, the Australian Institute of Marine Science said in its annual survey on Wednesday. … Because of record global heat in 2023 and 2024, the world is still going through its biggest — and fourth ever recorded — mass coral bleaching event on record, with heat stress hurting nearly 84% of the world’s coral reef area, including the Great Barrier Reef, according to the U.S. National Oceanic and Atmospheric Administration’s coral reef watch.” (08/06/25)
