Australia's Great Barrier Reef has suffered its most widespread coral bleaching on record, scientists said on April 7, 2020 in a dire warning about the threat posed by climate change to the world's largest living organism. James Cook University professor Terry Hughes said a comprehensive survey last month found record sea temperatures had caused the third mass bleaching of the 2,300-kilometre reef system in just five years.
