It’s the fourth global bleaching event since 1998, and has now surpassed bleaching from 2014-17 that hit some two-thirds of reefs, said the ICRI, a mix of more than 100 governments, non-governmental organizations and others. And it’s not clear when the current crisis, which began in 2023 and is blamed on warming oceans, will end.

“We may never see the heat stress that causes bleaching dropping below the threshold that triggers a global event,” said Mark Eakin, corresponding secretary for the International Coral Reef Society and retired chief of the Coral Reef Watch program of the U.S. National Oceanic and Atmospheric Administration. “We’re looking at something that’s completely changing the face of our planet and the ability of our oceans to sustain lives and livelihoods,” Eakin said.

There are heat tolerant coral species but it will result in some very significant biodiversity loss.

Ocean acidification is a harder problem.
