A worldwide assessment warns that almost all of the planet’s coral reef ecosystems face a high risk of collapse within the next 50 years. The main threats are warming oceans and marine heat waves, which place reefs under growing stress. Researchers say the outlook is serious, but local action can improve reefs’ chances of survival. Reducing pollution, limiting overfishing and managing coastal development could all help protect these ecosystems. Those measures are important alongside efforts to cut global emissions, which drive the broader warming threat. Coral reefs support rich marine life and are vulnerable to changes in ocean conditions, making the assessment a stark warning about their future. The findings point to a need for both local conservation and action on climate change to lower the risks reefs face.
