Great Barrier Reef Severe Bleaching

The bleaching is worst in the most pristine and remote parts of the reef north of Cairns, according to Terry Hughes, convenor of the National Coral Taskforce. “It’s the jewel in the crown of the Great Barrier Reef and it’s now getting a quite a serious impact from this bleaching event,” he said. “The northern reefs are bleaching quite badly now.”images

“These massive thousand-kilometer bleaching events didn’t happen thirty years ago,” he said. “No-one ever recorded a mass bleaching event in the 40s, 50s, 60s, 70s, until the middle of the 1980s … and the Great Barrier Reef didn’t bleach until 1998 for the first time.”

Hughes says we are heading towards a future where the Great Barrier Reef might bleach during every El Niño , which will put its existence at risk.
