"The Great Barrier Reef is experiencing another "mass bleaching event," according to the Great Barrier Reef Marine Park Authority. The government agency said that the widespread bleaching was caused by the high temperatures during Australia's record hot summer.
"Australia's lead management agency for the Great Barrier Reef can confirm mass bleaching is occurring on the Great Barrier Reef, with very widespread bleaching detected," the park authority said in a press release Thursday.
Dr. David Wachenfeld, chief scientist at the park authority, said in his weekly reef health update on Thursday that the unique ecosystem, located off Australia's north eastern coast, is now experiencing its third mass coral bleaching event in just five years."
