Coral bleaching now too frequent for reefs to recover, scientists say
Bleaching events now occur every five or six years instead of gaps that once stretched for decades, leaving reefs insufficient time to recover. Data spanning more than four decades from nearly 37,000 sites across 120 countries and territories show global coral cover running 9.5 per cent below historical norms in 2020-2024, according to the Global Coral Reef Monitoring Network.
