Global Coral Bleaching Event Affects Majority of World's Reefs
A recent study published in 2026 reveals that 84% of the world's coral reefs have been affected by a mass bleaching event that began in 2023, making it the most extensive coral bleaching event on record. This surpasses previous findings from a 2014–2017 global marine heatwave, during which over 50% of coral reefs experienced significant bleaching. The ongoing bleaching events continue to pose serious threats to coral ecosystems worldwide.
The study highlights the impact of warming ocean temperatures on coral health and marine ecosystems. Dr. Mark Eakin and the organization Corals and Climate have been involved in analyzing and reporting these developments. The research underscores the increasing risks to coral reefs from climate-related stressors and emphasizes the critical need for global monitoring and conservation efforts.
