Great Barrier Reef Suffers Its Most Widespread Mass Bleaching Event On Record (washingtonpost.com)

Surveys conducted by scientists at Australia's James Cook University and the Great Barrier Reef Marine Park Authority show that a summer of extreme heat has caused the reef to suffer a mass bleaching of unprecedented scale. Corals from the far north to the southern tip of the 1,400 mile-long ecosystem are experiencing severe impacts. It was also one of the reef's worst mass bleaching episodes in terms of intensity, second only to 2016.
