Climate change is destroying the Great Barrier Reef. This discovery could save it.
The Great Barrier Reef may not be so doomed after all.
Hundreds of the Australian reef's coral species are blossoming deeper in the ocean than biologists previously thought, a report published by The Royal Society on Tuesday reveals. Growing further from direct sunlight could save these species from coral bleaching caused by climate change and prove essential for their conservation, Science News says.
The world's largest coral reef has been decimated as climate change warms waters and strips corals of their bright colors, killing them. Deeper-growing corals are safer from climate change, but scientists thought only a few species could grow more than 100 feet from the surface. It turns out 195 species can actually grow in the shady, cold depths and not just near the sun, per the study. So when shallow-water corals die off, scientists might be able to "transplant" these "deep ocean corals" and repopulate the surface, Science News writes.

The study was published just two days after another promising reef report. Though bleaching may severely damage of Great Barrier Reef, corals that survived one season tended to tolerate hotter temperatures the following year, a study published Monday in Nature shows. It's not great that any corals are dying, scientists assure, but at least this suggests the strongest ones will live on and repopulate the reef.
