Far from bleached, reef’s in the pink
West Australian coral is doing fine while Queensland (Eastern) coral is extensively bleached. So any pretense that the Queensland situation is part of a global phenomenon is at least dubious. There's some very confused thinking about El Nino and La Nina below. The journalist appears to have the two mixed up
Scientists have discovered that the World Heritage-listed Ningaloo Reef off the West Australian coast — the largest fringing reef in Australia — has escaped any recent coral bleaching and that some areas are in the same condition as 30 years ago.
CSIRO ecologist Damian Thomson said yesterday a major study of the reef that ended this month had found that Ningaloo was unaffected by the current bleaching "event" that has hit Queensland’s Great Barrier Reef and other reefs off WA’s northern coast.
He said the research — funded by CSIRO and BHP Billiton through a $5.4 million partnership — showed Ningaloo was more resilient than expected.
"It’s really pleasing that Ningaloo hasn’t undergone any bleaching — it’s fantastic news actually," Mr Thompson said.
The clean bill of health will be welcomed by the tourism industry around Exmouth, a town reliant on thousands of visitors visiting the reef every year between April and July to snorkel with migrating whale sharks. Later this year, tourists will also be able to swim with humpback whales, which is expected to double the length of Exmouth’s $6m tourist season.
Conservationists are worried about the human impact on the reef and have also raised concerns in recent years about increased oil and gas exploration — including by BHP — close to Ningaloo Marine Park.
Mr Thomson said while coral bleaching remained a possible future threat to the reef, the sheer number of people visiting the area was its major challenge.
"It’s a relatively small tract of reef when you look at the extent of the Australian coastline, but the number of people that love holidaying there or going there for other activities, it is very well used. That is probably the main challenge, managing that."
Mr Thomson said bleaching tended to occur on Australia’s west coast during La Nina years, when strong currents from Indonesia pushed warm water south to Ningaloo. But during the recent El Nino, those strong currents had not occurred, resulting in cooler waters.
CSIRO research surveyed 70 sites at Ningaloo and found no coral bleached at locations where bleaching was recorded in 2010. At Osprey, on the western part of Ningaloo, results were as good as those taken in 1987. Ningaloo was declared a UNESCO World Heritage site in 2011 for its biological diversity and conservation significance.
The findings are for the first year of field work undertaken by the Ningaloo Outlook project, which aims to increase the ecological understanding of the reefs.

Warmists just LOVE the Great Barrier Reef
It enables them to tell SO many lies. That coral "bleaching" (expulsion of symbiotic algae) has been happening for millions of years goes unmentioned below -- as is the fact that corals have in the past coped with far greater temperature variations than anything we have seen recently. And corals are still with us, funnily enough.
They do respond to temperature, among other things, but the "bleaching" is mainly in order to recruit different varieties of symbiotic algae. And corals are hardier than they look. In "bleached" form they can survive for quite a while on just their normal filter feeding. "Bleached" corals are NOT dead.
And the present ocean warming is clearly due to El Nino, a temporary warming that is part of a natural cycle. It's actually the La Nina that normally follows El Nino that is the biggest concern. Corals are more likely to "bleach" in response to cooling than they are to warming.
And let me again mention my favourite fact about coral: In 1954 the USA exploded a 15 megaton thermonuclear device over Bikini atoll. And Bikini atoll had lots of coral. So there is no coral there at all now? Far from it. The corals there now are huge, abundant and thriving. So if coral reefs can recover from an H-bomb blast, why is a pissy one degree temperature rise in GBR waters of concern?
Corals at Bikini atoll today
Strange that all that goes unmentioned below, isn't it? You would not suspect any of it from the screeches below. The words below are "an orchestrated litany of lies", to quote a distinguished judge on another matter. The Waremists just want more funding and are prepared to lie and deceive to get it. Global warming is a global racket dreamt up by scientists for the benefit of scientists
The Federal Government’s plan to save the Great Barrier Reef is “totally inadequate,” and if whoever forms government doesn’t commit at least $10 billion this election the natural wonder is likely to be doomed, scientists at James Cook University have said.
This extraordinary warning comes from leading water quality expert Jon Brodie and Emeritus Professor Richard Pearson, who are speaking out after they published a paper this week. In an interview this morning, Brodie said the Reef “will never be in its full gory again, we can’t expect that, [but]it’s going to get worse unless we do something”.
The Scientists said the twin threats of poor water quality and climate change could put the Reef in “terminal” decline within five years, unless whoever forms government comes to office with a comprehensive, cohesive, and adequately-funded rescue plan.
The Coalition Government has released a plan, known as Reef 2050, but it scarcely mentions climate change and Brodie said it is “totally inadequate”. “I’m probably the leading water quality expert for the Great Barrier Reef over the last 30 years and I’m saying the water quality [aspect of the plan]is absolutely inadequate,” he said.
“It was meant to be a comprehensive plan, of course, but as has been pointed out by everyone, and particularly the Australian Academy of Science, it’s totally inadequate,” he said.
The James Cook University scientists said catchment and coastal management programs need to be funded in the order of $1 billion per year over the next ten years. “We need a plan to fix up water quality as best we can, to provide some resilience against the oncoming climate change impacts,” Brodie said.
The Great Barrier Reef has made headlines over recent months as 93 per cent of the Reef, which is the only living structure that can be seen from space, has been affected by coral bleaching.
Fuelled by warming waters, the coral bleaching event was the worst in recorded history. The uncompromising heat was a result of an El Nino climate system, superimposed over baseline temperatures already pushed up by climate change.
“Before climate change kicked in we simply never saw bleaching,” Professor Terry Hughes has previously told New Matilda. “It’s quite confronting that we’ve now got to the stage that every El Nino event – and they happen every few years – is a threat to the Great Barrier Reef,” said Hughes, the Director of the Australian Research Council’s Centre of Excellence for Coral Reef Studies.
The threats posed by climate change are exacerbated by plague-like outbreaks of Crown of Thorns Starfish, which are triggered by poor water quality. According to the James Cook University Scientists, the next outbreak is most likely to occur around 2025.
If we don’t make serious inroads at improving water quality by then, the fate of the Reef looks grim.
Brodie and Emeritus Professor Pearson are calling for management of the Reef to be extended beyond the bounds of the World Heritage Area, north to the Torres Strait, south to Hervey Bay, and inland to include the Great Barrier Reef catchment.
This would of course come at a cost. But Brodie points out that while $10 billion over ten years “may seem like a lot of money, we know that amount would be effective and it’s small by comparison to the economic worth of the Reef, which is around $20 billion per year”.
Current Federal funding, he said, “is almost nothing”. And that doesn’t look likely to change. “So far in the election campaign, we’ve seen no major commitments about the Great Barrier Reef at all from anybody really,” Brodie said.
The Great Barrier Reef Campaign Director at the Australian Marine Conservation Society, Imogen Zethoven said “the massive coral bleaching taking place right now on the Reef and the latest science over recent months all point in one direction: The outlook for the Reef is dire and we must act now.
“Things are worse than we thought for the Reef’s future, we are close to the brink of what this fragile ecosystem can tolerate without a credible plan for restoring it to good health,” she said.
“Australia’s current plans to protect the Reef are inadequate, short-sighted, lack appropriate funding and will not prevent its decline.”

Wow! Somebody who knows what he is talking about on coral bleaching
There is a long article on Watts that reviews the science of what is known of the coral reef life-cycle. It has lots of surprises for people who have heard only the cries of disaster from Warmists. The single fact that stood out to me was that coral bleaching is most often a response to COOLING, not warming.
The article gives particular attention to the utterances of Warmists like Hoagy and completely demolishes them. It gives good grounds for regarding Hoagy as nothing but a fraud.
I have previously noted that coral bleaching is not coral death and that corals are very resilient to damage but this article gives chapter and verse of that. Anyone interested in the health of coral reefs needs to read this article. You will laugh at all future Warmist claims if you do.
