Study | Safe havens for coral reefs likely to shrink in coming years

In 2015 and 2016, record ocean temperatures triggered coral bleaching events around the world — from Hawai‘i to the Caribbean to Australia — turning once-healthy polyps into ghostly skeletons. But some reefs managed to remain intact due to the cooling effects of upwelling and ocean currents.

According to a new study, these special coral reefs, called “refugia,” could disappear in the very near future as human-induced climate change continues to heat up the world.
