World Heritage Great Barrier Reef headed for climate change doom – UNESCO

UNESCO warns climate change means time is running out for World Heritage Great Barrier Reef http://www.couriermail.com.au/news/queensland/unesco-warns-climate-change-means-time-is-running-out-for-world-heritage-great-barrier-reef/news-story/4765a338156dd9e5b9b2c1d2b357d655?nk=ba26857f63080120cbd5fc74c94d3959-1498465693, Daryl Passmore, The Courier-Mail June 25, 2017

THE Great Barrier Reef will be dead by the end of this century without a reduction in greenhouse gas emissions, a world-first study warns.

The threat to Australia’s natural wonder is detailed in the first global assessment of climate change impacts on coral, released yesterday by the United Nations Educational, Scientific and Cultural Organisation (UNESCO).

It comes just a month before the World Heritage Committee meets in Poland to consider the condition of the Great Barrier Reef and the effectiveness of a management plan introduced by the Queensland and federal governments to protect it.

“Soaring ocean temperatures in the past three years have subjected 21 of 29 World Heritage reefs to severe and/or repeated heat stress, and caused some of the worst bleaching ever observed at iconic sites like the Great Barrier Reef,’’ it says.

“The analysis predicts that all 29 coral-containing World Heritage sites would cease to exist as functioning coral reef ecosystems by the end of this century under a business-as-usual emissions scenario.”

The report calls on all countries with World Heritage coral reefs to act to reduce net greenhouse emissions to zero in order to save them.

On current trends, the assessment predicts, global warming will increase by 4.3C by 2100.

Under that scenario, the Great Barrier Reef would suffer severe coral bleaching twice a decade by 2035 – “a frequency that will rapidly kill most corals present and prevent successful reproduction necessary for recovery of corals.’’

The diversity of life on reefs has led to them being been dubbed the “rainforests of the sea”. Covering less than 0.1 per cent of the ocean floor, they host more than a quarter of all marine fish species.

Australian Marine Conservation Society spokeswoman Imogen Zethoven said the Great Barrier Reef and other World Heritage reefs were in grave danger from climate change, mainly driven by the burning of coal.

“Yet the Australian government appears hell-bent on making the problem worse by pushing ahead with Adani’s monstrous coal mine (planned for central Queensland), talking up a coal-fired power station next to the Great barrier Reef and failing to do its fair share of global pollution reduction,” she said.

“The Australian government is not only placing our Great Barrier Reef and the 70,000 jobs that depend on it at grave risk, it is endangering the future of World Heritage coral reefs around the world,” Ms Zethoven said.

“The majority of Australians believe the state of our reef is a national emergency, but the Australian government doesn’t care.”
