Global Coral Reefs Suffer Mass Bleaching During Three-Year Ocean Heat Wave
A recent study highlights the devastating impact of climate change on marine ecosystems, revealing that a prolonged ocean heat wave from 2014 to 2017 caused moderate or severe bleaching in more than half of the world's coral reefs. The research, led by C. Mark Eakin, former head of Coral Reef Watch at the National Oceanic and Atmospheric Administration (NOAA), indicates that approximately 15% of these reefs experienced moderate or greater mortality. Coral bleaching occurs when rising water temperatures cause corals to expel the symbiotic algae that provide them with food and vibrant colors. While recovery is possible, repeated or extended heat events often lead to permanent death. The report emphasizes that although restoration efforts are underway, they will be futile without addressing the root cause: global climate change. As ocean temperatures continue to rise, intense heat waves pose an existential threat to these diverse ecosystems, which support countless marine species. Experts urge immediate action to mitigate climate change to prevent further irreversible damage to coral reefs worldwide.
