Record-breaking coral bleaching affecting 84% of the world's reefs is underway, surpassing previous events in intensity. This fourth global bleaching event since 1998 is attributed to warming oceans, reaching record sea surface temperatures. The damage threatens marine biodiversity, coastal protection, and livelihoods. While conservation efforts are underway, scientists emphasize the urgent need to reduce greenhouse gas emissions as the primary solution to prevent further coral reef destruction.
