In some parts of Australia’s much-loved reef, 70 percent of the coral has been killed by bleaching. Australia is pledging vast amounts of money to mitigate the loss and stop a UNESCO downgrade of its status.
Coral bleaching at Australia’s heritage-listed Great Barrier Reef was worse that first thought, government scientists announced on Monday.
Up to 70 percent of the coral has been killed in some parts of the 2,300-kilometer reef system, due to rising sea temperatures during March and April.
“As has been the case with reefs across the world, the Great Barrier Reef has experienced significant and widespread impacts over the last two years,” the chairman of the Great Barrier Reef Marine Park Authority (GBRMPA), Russel Reichelt, said in a statement.
