A new comprehensive analysis finds that 75 percent of the world’s coral reefs are currently threatened by local and global pressures. For the first time, the analysis includes threats from climate change, including warming seas and rising ocean acidification. The report shows that local pressures— such as overfishing, coastal development, and pollution— pose the most immediate and direct risks, threatening more than 60 percent of coral reefs today. “Reefs at Risk Revisited,” the most detailed assessment of threats to coral reefs ever undertaken, is being released by the World Resources Institute, along with the Nature Conservancy, the WorldFish Center, the International Coral Reef Action Network, Global Coral Reef Monitoring Network, and the UNEP-World Conservation Monitoring Center, along with a network of more than 25 organizations. Launch activities are taking place in Washington, D.C., London, Malaysia, Indonesia, the Caribbean, Australia, and other locations around the world.
“This report serves as a wake-up call for policy-makers, business leaders, ocean managers, and others about the urgent need for greater protection for coral reefs,” said Dr. Jane Lubchenco, under secretary of commerce for oceans and atmosphere and NOAA administrator. “As the report makes clear, local and global threats, including climate change, are already having significant impacts on coral reefs, putting the future of these beautiful and valuable ecosystems at risk.” Local pressures – especially overfishing and destructive fishing – are causing many reefs to be degraded. Global pressures are leading to coral bleaching from rising sea temperatures and increasing ocean acidification from carbon dioxide pollution. According to the new analysis, if left unchecked, more than 90 percent of reefs will be threatened by 2030 and nearly all reefs will be at risk by 2050. “Coral reefs are valuable resources for millions of people worldwide. Despite the dire situation for many reefs, there is reason for hope,” said Lauretta Burke, senior associate at WRI and a lead author of the report. “Reefs are resilient, and by reducing the local pressures we can buy time as we find global solutions to preserve reefs for future generations.
