June 11 , 2026 15 hrs 0 min 60 0

Scientists have reported that the fourth global coral bleaching event, the fastest and most widespread on record, likely ended in mid-2025.
The event was confirmed by the National Oceanic and Atmospheric Administration (NOAA) on 15 April 2024.
It caused bleaching-level heat stress across 84% of the world's coral reef areas.
Coral reefs in 83 countries and territories across the Pacific, Atlantic, and Indian Oceans were affected.
The event likely concluded after the Western Australia coral bleaching episode in early 2025.
Scientists warn that rising ocean temperatures could lead to more frequent coral bleaching events in the future.
