Coral reefs are facing significant losses. A decline of nearly 10 percent has occurred since 2020. This downturn is attributed to global warming, which causes warm water to harm the algae that corals rely on.

The Global Coral Reef Monitoring Network has tracked four major coral bleaching events since 1998, each resulting in substantial losses.

Further information on the report's findings, including the impact on hard coral cover, is available from the source, which also provides details on the extent of the damage to reefs worldwide.
