Global Study Finds 9.5% Decline in Coral Reef Cover Due to Frequent Bleaching
A global study by the Global Coral Reef Monitoring Network reveals that coral reefs are bleaching more frequently due to rising ocean temperatures, reducing recovery time and causing a 9.5% decline in hard coral cover between 2020 and 2024 compared to 1980-2009. Despite some regional recoveries, such as in the western Indian Ocean and South Asia, overall coral cover is at risk of irreversible decline, threatening marine biodiversity and coastal resilience. The findings highlight climate change's impact on reef ecosystems ahead of the COP31 climate conference.
