Event Summary

Scientists warned that Australia's Australia — Great Barrier Reef faces a very high risk of extreme bleaching and ecosystem collapse due to the 2026 El Niño–Southern Oscillation. Morgan Pratchett of James Cook University stated at the International Coral Reef Symposium in Auckland that the next major disturbance could lead to localized species extinctions and widespread ecosystem collapse. The reef, a major tourism draw, avoided UNESCO's endangered list this month despite concerns. Hard coral cover declined substantially in 2024-2025, marking the sixth mass bleaching event since 2016. Ove Høegh-Guldberg of the University of Queensland criticized government inaction, warning of global coral reef threats.
