Great Barrier Reef can no longer be saved

The Great Barrier Reef can no longer be saved in its present form partly because of the “extraordinary rapidity” of climate change, experts have conceded.

Like coral across the world, the reef has been severely damaged by the warming of the oceans with up to 95 per cent of areas surveyed in 2016 found to have been bleached.

Bleaching is not always fatal but a study last year found the “largest die-off of corals ever recorded” with about 67 per cent of shallow water coral found dead in a survey of a 700km stretch.

Now experts on a committee set up by the Australian government to improve the health of the reef have revealed that they believe the lesser target of maintaining its “ecological function” is more realistic.

The concept of ‘maintaining ecological function’ refers to the balance of ecological processes necessary for the reef ecosystem as a whole to persist, but perhaps in a different form, noting the composition and structure may differ from what is currently seen today.
