Global hard coral cover has been declining due to more frequent marine heatwaves. However, corals in certain regions are showing resilience. Hard coral cover has remained stable in East Asian seas, bucking the global trend.

This stability is notable given the decline in hard coral cover worldwide. The reasons for this variation are not specified here, but further information may be available from the source.

Overall, while the global outlook for coral reefs is concerning, some areas are holding out against the decline.
