Great Barrier Reef 'not dying', Australia insists

The Great Barrier Reef is "not dying", Australia insisted Friday as it updated UNESCO on efforts to protect the natural wonder while scientists blasted a lack of urgency in dealing with climate change.

Canberra last year narrowly avoided the UN body putting the site on its endangered list and was ordered to report to the World Heritage committee by December 1 on its "Reef 2050" rescue plan.

The giant ecosystem—a major tourist attraction—is under pressure from farming run-off, development, the crown-of-thorns starfish and , which led to its worst-ever bleaching event this year that devastated swathes of coral.

In the report, the government said 32 of the plan's 151 actions to improve the reef had been achieved. Another 103 were under way, four were delayed, and 12 were not yet due.

"When we came to government we inherited a reef on UNESCO's endangered watch list," Environment Minister Josh Frydenberg told Sky News.

"We've done everything possible since that time to put in place a plan, to invest huge amounts of resources to improve , to work with the farming community to tackle the crown-of-thorns starfish and to preserve this natural wonder of the world.

"We have to put the facts on the table," he added. "The reef is not dead, it's not dying, it's resilient, it's healthy and we've made great strides forward in the last few years."

The government has committed more than Aus$2.0 billion (US$1.5 billion) to protect the reef over the next decade with the update highlighting progress on to prevent sediment run off, which helps spawn the coral-eating starfish.

It also pointed to a ban on sea-based disposal of dredge material in the area and restrictions on new port developments.

But the rescue plan included no new funding or commitments to tackle climate change despite acknowledging this was the reef's biggest threat.

This year's bleaching, due to warming sea temperatures, killed two-thirds of shallow-water corals in the north of the 2,300-kilometre (1,400-mile) long reef, although central and southern areas escaped with less damage.

'Not credible'

The update said Canberra was acting on global warming through the United Nations talks that led to the recent Paris climate deal, but scientists said it was not enough to rein in Australia's carbon pollution.

"Funding water quality efforts on the reef while failing to do anything about climate change is a bit like fixing a window while the house is on fire," said Tim Flannery from the independent Climate Council.

"I'm not even sure you can call a plan that includes no new funding and no new actions on climate change a plan—it's simply a re-announcement of old commitments."

Greenpeace Australia was equally scathing, saying it was unacceptable that while recognising the impact of global warming on the reef the government "then completely fails to do anything about it".

"This plan does not even consider a significant reduction in carbon emissions so is simply not credible," said reef campaigner Shani Tager.

"If the government was serious about protecting the Great Barrier Reef, a ban on new coal mines would have been the first point in its report to UNESCO."

Frydenberg said the government was committed to tackling and recently ratified the Paris agreement, the world's first universal climate pact, which came into force in early November.

"We've adopted targets that are 26 to 28 percent reduction of our emissions by 2030 on our 2005 levels. On a per capita basis, that's more than 50 percent," he said.

"We are doing a lot of things in a lot of areas and the is strong."

With heavy use of coal-fired power and a relatively small population of 24 million, Australia is considered one of the world's worst per capita greenhouse gas polluters.

"Once they expel all the algae, they die." ... and states, "There's nothing at all from stopping one event, one El Niño from wiping out the Great Barrier Reef in a month."; "El Niño exacerbates Great Barrier Reef bleaching; Financial Times - World"; 3:39; https://www.youtu...mp;t=16s

The issue is 30C/86F water being the limit for most of the oceans coral which thrive at 28.5C/83.3F so not much room before the algae are expelled at 30C, considering an El Niño is about decadal and recent reports finding die-off continuing where corals were damaged it's early to call off the alarm bells.

Labs have shown it takes about a week above 30C to cause a bleaching, the oceans are absorbing 93% of the excess heat most of which is above 300m and to top it off acidification is some 10-times above an extinction event to add to the wonder at nothing being done, as if this isn't going on.

Isn't that insanity?
