Great Barrier Reef Was Considered "Too Big To Fail" By Oz Scientists. It Wasn't. Oops.
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 earths 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.
There are so many corals, and its been disturbed many times in the past, said Andrew Baird, chief investigator at the research center and one of the papers lead authors. We never thought wed see this happen, he said.
The study is the first to show the collapse of fundamental ecosystem processes in a marine environment, Professor Baird said. We thought the Barrier Reef was too big to fail, he said, but its not.
