"MELBOURNE, Australia — For millenniums, ecosystems have withstood fires, floods, heat waves, drought and even disease by adapting and rebuilding their biodiverse communities.
But according to new research, there is a limit to what even the largest and most resilient places can stand, and climate change is testing that limit by repeatedly disturbing one of the earth’s most precious habitats: the Great Barrier Reef.
The study, released Wednesday in the journal Nature by researchers from the ARC Center of Excellence for Coral Reef Studies in Australia, monitored the death and birth of corals following ocean heat waves that caused mass bleaching of the Great Barrier Reef in 2016 and 2017.
Not only did many of the adult corals die off, but for the first time, researchers observed a significant decline in new corals settling on the reef, compromising its capacity to recover."
