NOAA reports that nearly two-thirds of the world’s coral reefs have experienced heat stress triggering bleaching, exacerbated by climate change and El Nino. Coral Reef Watch coordinator Derek Manzello expresses deep concern over the extreme ocean temperatures causing mass bleaching in 62 countries, including India and Sri Lanka. The Atlantic Ocean, with 99.7% of reefs affected, faces significant damage. Huatulco, Mexico, reports coral mortality up to 93%. The Southern Caribbean anticipates worsening bleaching this summer, posing a threat to the Great Barrier Reef and Mesoamerican Barrier Reef.
