The Great Barrier Reef has recorded its most significant coral bleaching event to date, largely attributable to climate change-induced heat stress, as confirmed by the Australian Institute of Marine Science. Survey data shows that coral cover in the southern third of the reef fell to 26.9 percent, representing a one-third decline. This loss is the most extensive single-year drop measured in 39 years. Mass bleaching events are intensifying and becoming more frequent, necessitating reductions in greenhouse gas emissions and effective management strategies to aid coral adaptation and recovery.
The Great Barrier Reef has suffered its most widespread coral bleaching on record due to record ocean temperatures in 2024, as reported by the Australian Institute of Marine Science.
Coral cover declined by almost one-third, down to just 26.9 percent, in the southernmost third of the reef, marking the largest drop in a single year since monitoring began.
Mass bleaching events on the Great Barrier Reef are becoming more intense and frequent, underscoring the urgent need for greenhouse gas emissions reduction to protect these ecosystems.
The Great Barrier Reef, a World Heritage Site, is home to the world's largest collection of coral reefs, 1,500 species of fish, and numerous other marine animals.
