Scientists Find 166,000 Square Kilometers Where Coral Can Survive Climate Warming

Researchers have mapped roughly 166,000 square kilometers of coral reef with the physical conditions needed to survive warming oceans—cooler currents, stable temperatures, zones where coral can recover between heat stress events. The study, published in Conservation Letters, represents the first global count of these climate refugia, offering a clearer picture of where reefs might endure as temperatures rise.
