Status of Coral Reefs of the World: 2025

From Science to Action: Securing the Future of Coral Reefs

The most comprehensive assessment to date of the status and trends of coral reefs, from 1980 to 2024, at global and regional scales.

Coral reefs are among the world’s most valuable natural assets — living infrastructure supporting food security, livelihoods, coastal protection, economies, biodiversity and cultural identity for close to one billion people. But they are changing at an unprecedented rate across many regions, and the primary driver is climate change. As ocean temperatures continue to climb and local pressures mount, the window to safeguard these ecosystems is rapidly closing — making timely, evidence-based action more critical than ever.
