Red Sea corals' heat tolerance offers hope for climate crisis

Reefs from Gulf of Aqaba in the Red Sea survived rise of seven degrees, say marine scientists

The scientists cranked the heat above the lethal threshold, and waited for the corals to die.

We were heating the water one degree above the summer maximum temperature," says Anders Meibom, a researcher with the Institute of Earth Sciences at the University of Lausanne. On the Great Barrier Reef, after a couple of weeks of that they'd start dying."
