What is the extent of the current global coral bleaching event and what are its immediate implications for marine ecosystems?

The severity of global coral bleaching has reached a record high, affecting 84% of the world's coral reefs. This is the fourth global bleaching event since 1998, surpassing the 2014-2017 event which impacted two-thirds of reefs. The current crisis, beginning in 2023, is attributed to ocean warming and its end is uncertain.
