The Great Barrier Reef has suffered its most widespread coral bleaching on record, according to a new Australian government report, as ocean temperatures soared in 2024.
The Australian Institute of Marine Science (AIMS) said on Wednesday that it surveyed the health of the reefs between August 2024 and May 2025 and found the “most spatially extensive” bleaching since records began in 1986, which was “predominantly driven by climate change-induced heat stress”.
