Global Coral Bleaching Event Threatens Reefs Worldwide
The NOAA warns of a potential fourth mass coral bleaching event, with the Great Barrier Reef and other tropical reefs at risk due to climate change and El Niño.
- The U.S. National Oceanic and Atmospheric Administration (NOAA) indicates the world is on the verge of a fourth mass coral bleaching event, potentially the worst in history.
- Southern Hemisphere reefs, including the Great Barrier Reef, are set to bleach in the coming months, following record ocean heat.
- Previous mass bleaching events occurred in 1998, 2010, and 2014-2017, with the Great Barrier Reef losing nearly a third of its corals during the last event.
- Coral bleaching, triggered by heat stress, can devastate ocean ecosystems, fisheries, and tourism-based economies.
- NOAA awaits final confirmation from Indian Ocean scientists to officially declare the fourth global mass bleaching event.
