Reuters's Gloria Dickie and Alison Withers are reporting on coral bleeching by climate change. 

Global warming has triggered the fourth global coral bleaching event, affecting reefs across 54 countries and territories since February 2023. This event, confirmed by the U.S. National Oceanic and Atmospheric Administration's Coral Reef Watch and the International Coral Reef Initiative, marks a significant increase in ocean surface temperatures due to climate change and El Niño patterns. The bleaching, a response to abnormal water temperatures, causes corals to expel vital algae, jeopardizing their survival. This year's event, potentially the most extensive yet, has seen unprecedented levels of heat stress on corals, particularly in the Caribbean and the Great Barrier Reef, raising concerns among scientists about the future recovery and sustainability of coral ecosystems globally. The recurring nature of such events challenges previous models and underscores the urgent need to curb carbon emissions to protect these vital marine habitats.
