Can Red Sea Corals Save the Worlds Reefs?

The Red Sea contains some of the world’s hottest and saltiest seawater.

Growing heat and acid tolerant corals in the Eritrean Red Sea might be the next big step to save hot water devastated reefs across the planet.


Hot water tolerant Red Sea corals could be the key to saving the worlds reefs. It will take an international effort to create the massive coral nurseries here in the Red Sea needed to begin to bring back to life the enormous areas of bleached dead coral reefs in places like The Great Barrier Reef in Australia, or from the coasts of Florida to the Indian Ocean, but it can be done.

Red Sea corals living in shallow waters here in the historic Zula Bay in Eritrea annually tolerate water temperatures of up to 37℃ (98°F) with only moderate bleaching, with the bleached portions able to recover once water temperatures go down. If all species present tolerate these high temperatures, there will be species that can tolerate even higher levels of temperature stress. Continue reading Can Red Sea Corals Save the Worlds Reefs?
