surveyed this year was bleached in the fourth such mass event in seven years in the world\u2019s largest coral reef ecosystem, Australian government scientists said.<\/p>\n<p>Bleaching is caused by global warming, but this is the reef\u2019s first bleaching event during a La Ni\u00f1a weather pattern, which is associated with cooler Pacific Ocean temperatures, the Great Barrier Reef Marine Authority said in its annual report released late Tuesday that found 91 percent of the areas surveyed were affected.<\/p>\n<p>Bleaching in 2016, 2017 and 2020 damaged two-thirds of the coral in the famed reef off Australia\u2019s eastern coast.<\/p>\n<p>Coral bleaches as a heat stress response and scientists hope most of the coral will recover from the current event, said David Wachenfeld, chief scientist at the authority, which manages the reef ecosystem.<\/p>\n<p>\u201cThe early indications are that the mortality won\u2019t be very high,\u201d Wachenfeld said on Wednesday.<\/p>\n<p>\u201cWe are hoping that we will see most of the coral that is bleached recover and we will end up with an event rather more like 2020 when, yes, there was mass bleaching, but there was low mortality,\u201d Wachenfeld added.<\/p>\n<figure class=\"wp-block-image size-large\"><img decoding=\"async\" loading=\"lazy\" width=\"1024\" height=\"682\"

the Climate Council, an Australia-based group that tracks climate change, said the report demonstrated the reef\u2019s survival depended on steep global emission cuts within the decade.<\/p>\n<p>\u201cThis is heartbreaking. This is deeply troubling,\u201d Bradshaw said. \u201cIt shows that our Barrier Reef really is in very serious trouble indeed.\u201d<\/p>\n<p>Last December, the first month of the Southern Hemisphere summer, was the hottest December the reef had experienced since 1900.
