Mass Coral Bleaching Event at Australia’s Great Barrier Reef
Australia’s Great Barrier Reef is experiencing its fifth mass coral bleaching event since 2016 due to heat stress, a major threat to coral reefs worldwide. Climate change is elevating ocean temperatures, making bleaching events more frequent. El Niño conditions in 2023 compounded the issue, and protecting the reef requires global emissions reduction and local management.
