article: mass coral bleaching now affecting half of great barrier reef

Two weeks ago, the Great Barrier Reef Marine Park Authority reported half the coral in the northern parts of the reef were dead. Hughes said that was consistent with reports from divers north of Port Douglas. Hughes said this was by far the worst bleaching event to have hit the Great Barrier Reef. He said it was three to four times worse than in 1998 or the second great bleaching in 2002. Last year, the Great Barrier Reef narrowly escaped being listed as “in danger” by Unesco, even though environmental groups said it clearly met the criteria. Hughes said the “outstanding universal value” of the reef was now “severely compromised”. Ariane Wilkinson, a lawyer at Environmental Justice Australia, said the bleaching might cause Unesco to reconsider its decision. “[Unesco] weren’t scheduled to examine the reef this year but in light of the terrible bleaching it is entirely possible that they may decide to look at the reef,” she said. “If the World Heritage system is to have any value, it must address the most serious threats to the most iconic examples of world heritage,” she said. “If any site falls into this category, it is the ... Great Barrier Reef.”
