Accident Leads to Incredible Discovery, Regrowing Coral Reefs Like Never Before

When you have a task to complete, many times it seems best to hunker down and focus solely on finishing that task until it's done. Whether that's writing a novel, making sales calls or writing lesson plans, putting everything else out of your mind and getting to work is a proven means to accomplish your goals.

When you have blinders or tunnel vision, though, you often forget to stop to smell the roses or see what's going on around you and what valuable lessons or insights you might be missing.

Plenty of scientists have made discoveries by accident, and have found useful inventions or information in their pursuit of something completely different. That's how we've gotten duct tape, super glue and even microwaves.

Now another scientist, Dr. David Vaughan, has made a discovery that could potentially regrow coral reefs in a fraction of the time it would normally take. According to BBC, it started with brokenness.

"Little did I know that one elkhorn coral attached itself to the bottom of the aquarium," Vaughan said. "So when I went to move it, it stuck, and I heard a breaking sound."

"And it had broken into many tiny pieces. They grew back to the same size in just a few weeks that it had taken three years to grow."

Upon realizing what this could mean, he tested it out on more and more species of coral until he confirmed that this fragmentation method worked brilliantly with all of the Florida Keys varieties.

The painstaking process of growing coral has been obliterated by this discovery. Under normal conditions, it can take corals up to seven decades to reach maturity; now, it could take as few as three.

Being able to regrow corals nearly 40 times faster than before means a lot of reefs could be restored.

"Corals the size of a small car could be 200-500 years old, so it might take centuries for it to come back. We now take a coral the size of a golf ball and cut it into 20 to 100 microfragments," Vaughan said.

"Each fragment grows back to that size in as little as a few months, and when they touch each other as they're growing, they recognize each other as themselves and fuse back together."

Vaughan has some big plans for the future and has even stayed on longer so he can see the coral reefs regrown.

"This is now a new discovery that can give real hope for our coral reefs that has never been there before," he told BBC. "So I postponed my retirement until I see a million corals replanted back on the reef."

Coral Reef Island Initiation and Development Under Higher Than Present Sea Levels

Higher sea levels will cause some coral islands to GROW

H. K. East et al.

Abstract

Coral reef islands are considered to be among the most vulnerable environments to future sea level rise. However, emerging data suggest that different island types, in contrasting locations, have formed under different conditions in relation to past sea level. Uniform assumptions about reef island futures under sea level rise may thus be inappropriate. Using chronostratigraphic analysis from atoll rim islands(sand- and gravel-based) in the southern Maldives, we show that while island building initiated at different times around the atoll (~2,800 and~4,200 calibrated years before present at windward and leeward rimsites, respectively), higher than present sea levels and associated high-energy wave events were actually critical to island initiation. Findings thus suggest that projected sea level rise and increases in the magnitude of distal high-energy wave events could reactivate this process regime, which, if there is an appropriate sediment supply, may facilitate further vertical reef island building.

Plain Language Summary

The habitability of reef island nations under climate change is a debatedand controversial subject. Improving understanding of reef island responses to past environmental changeprovides important insights into how islands may respond to future environmental change. It is typically assumed that all reef islands will respond to environmental change in the same manner, but suchassumptions fail to acknowledge that reef islands are diverse landforms that have formed under different sealevel histories and across a range of settings. Here we reconstruct reef island evolution in two contrastingsettings (in terms of exposure to open ocean swell) in the southern Maldives. Important differences in islanddevelopment are evident between these settings in the timings, sedimentology, and modes of islandbuilding, even at local scales. This implies that island responses to climate change may be equally diverse and site-specific. We present evidence that island initiation was associated with higher than present sea levelsand high-energy wave events. Projected increases in sea level and the magnitude of such high-energy waveevents could therefore recreate the environmental conditions under which island formation occurred. If thereis a suitable sediment supply, this could result in vertical island-building, which may enhance reef island future resilience.

Could our reefs be saved after all? Weed-like cauliflower coral has evolved unique immunity genes that means it could survive global warming

So a very vigorous coral is a "weed".  The Green/Left never miss a chance at negativity.  And saying it has developed "immune" responses to survive is a stretch.  Starfish, lowered water levels, and  unexpected heat variations are the big enemies of coral, not viruses and bacteria

A common coral has evolved unique strategies to cope with environmental change. Scientists say the cauliflower coral - which is traditionally thought of as a weed - could be one of the only corals to survive dramatic changes in the climate.

As one of the most abundant and widespread reef-building corals in the world it could be crucial to the future survival of the world's reefs, scientists found.

Researchers from the University of Miami say the common coral species might have evolved unique immune strategies to cope with environmental change.

Roughly 30 per cent of the cauliflower coral's (Pocillopora damicornis) genome was unique compared to several other reef-building corals.

This adaptation could be crucial for the long-term survival of coral reefs as climate change and ocean acidification continue to ravage the oceans.

'This coral is traditionally thought of as a weed, and yet it may be one of the last corals to survive environmental changes such as climate change,' said senior author of the study Nikki Traylor-Knowles, an assistant professor of marine biology and ecology at the University of Miami.

To conduct the research, scientists extracted and sequenced the genomic DNA from two healthy fragments and two bleached fragments of P. damicornis.

Their genome was then compared to publicly available genomes for several other coral species.

'The study shows that this is an important coral with a very complex and unique immune system, which may explain why it is able to survive in so many different locations,' said the paper's lead author Ross Cunning who is now a researcher at Shedd Aquarium.

The results suggest that the evolution of an innate immune system has been a defining feature of the success of hard corals like P. damicornis.

The immune system of corals, like humans, is vital to protect overall health and deal with changes in its surroundings.

If an animal has a stronger immune system then it will be better equipped to deal with environmental changes.

These new findings, published in Scientific Reports, suggest that some corals have many more immunity genes than would be expected.

'This study helps us better understand how corals deal with stress,' said Dr Traylor-Knowles.

'Its complex immune system indicates that it may have the tools to deal with environmental change much more easily than other corals.'

Grim reef bleaching forecast

Prophecies, prophecies. They do this forecast most years.  I come from Australia's Far North, adjoining the reef, and I can in fact remember such earnest forecasts from when I was a kid --60 years ago.  But the reef is still there, much the same as ever.  It has ups and downs but it always bounces back.  It has bounced back recently in fact, something not mentioned below -- which is why they stick to prophecy

Predictions that the Great Barrier Reef could suffer severe coral bleaching by the end of summer is an urgent warning for the Federal Government to take immediate climate action, says the Australian Marine Conservation Society.

The US National Oceanographic and Atmospheric Administration’s (NOAA) tentative forecast, out today, predicts the entire reef has a 60 percent chance of being subject to "bleaching alert level one"—meaning bleaching is likely— by March 2019, with possible coral mortality in some areas.

“How much more of the Great Barrier Reef has to die before the Federal Government acts on climate change?,” said AMCS spokesperson Imogen Zethoven.

“While our Reef is in danger, our politicians continue to ignore the issue of climate change with no credible plan to reduce pollution.

Parts of the southern half of the Reef are on higher alert with coral mortality likely in some areas, according to NOAA. An El NiƱo event could increase the odds of a severe bleaching event.

“The Reef is already suffering heat impacts. Add drought, bushfires and heatwaves into the mix and all Queenslanders, including our marine life, are in for a tough summer,” said Zethoven.

“The government’s claims that it is looking after the Reef—and the millions of taxpayer dollars spent on this—ultimately count for very little if it continues to ignore the greatest threat to the reef.

“By failing to protect the Reef, the Federal Government is also gambling with the 64,000 jobs that are dependent on the Reef, and the $6 billion that it generates every year for the Queensland economy.”

“The Government knows what the solutions to this are all too well: no new coal mines, including Adani’s monstrous Carmichael mine, a rapid transition to renewable energy, a phase out of all coal-fired power stations by 2030 and an immediate end to all fossil fuel subsidies.”

“But instead of acting on these recommendations, the government continues to pander to the demands of the fossil fuel industry instead of delivering a cleaner, safer future for Australia.

“The Government is on notice ahead of the next election. Australians want the Government to protect the Reef and its amazing wildlife. The time to act is now.”

Coral Bleaching Just As Bad Or Worse 400 Years Ago

The Greenie lies about coral bleaching, excerpts:

Large-scale coral bleaching has raised concern about the future of the ecosystems and the impact their loss could have on biodiversity.

The fact that we are seeing an increase in bleaching even in these tough corals highlights just how serious the threat of coral bleaching is. –Dr Sebastian Hennige, researcher

The teams found the frequency of bleaching has increased since the 1800s and, despite corals’ ability to recover, there are fears they could now be approaching a "critical threshold".

Dr Nick Kamenos from Glasgow’s School of Geographical and Earth Sciences said: "It’s clear in the core data we examined that bleaching has been occurring on the Great Barrier Reef for at least 400 years, but the frequency of bleaching events has increased markedly since the early 1800s and those events have affected 10% more corals since the late 1700s.

The facts:

The claim that the frequency of bleaching events has increased markedly since the early 1800s is an utterly dishonest one. Here is the actual graph from the paper itself:



The relevant chart is "B", which shows the number of years in each decade when at least 20% of corals were affected.

As you can see, although there has been a rise since 1800, there is little difference between recent decades and the 18thC. Indeed bleaching was far worse in the 1890s and 1750s.

Worse still for the alarmists, chart "C" shows little change in the percentage of corals bleached per decade.

There is the usual nonsense about how things will get much worse. But the actual facts show a completely different picture.

Coral reef corruption

There are some people who should never do interviews. At the head of that list is the managing director of the Great Barrier Reef Foundation, Anna Marsden.

One of the interviews she did this week gave train wrecks a bad name. This is a woman who has never heard of the phrase "stop digging". This week she was brandishing her shovel and seemed utterly determined to bury the $444 million grant the foundation received from the Turnbull government.

The opposition just couldn’t believe its luck as she poured fuel on a fire already burning out of the government’s control.

In her defence, all I can say is that the decision to grant the foundation this massive sum, which Marsden famously declared was like "winning Lotto", stinks to high heaven and no one is capable of justifying it.

Environment Minister Josh Frydenberg has waffled and struggled to explain how it came about. He is a competent minister whom I fear is covering for the real culprit in all of this — the Prime Minister himself.

Then again, how could you ever justify showering this foundation with such largesse when it didn’t even request it? This was money that simply fell out of the sky and into its grateful lap. Depending upon whom you believe, the foundation employed between eight and 12 people at the time of the grant announcement. Given there could be up to 1000 requests for grants, just how would it be expected to manage the task?

The answer would have to be to hire more people, which begs the question — how much of each dollar given reaches the reef and how much is spent on administration? You would be entitled to believe that this sort of question could be readily answered by the government simply checking its due diligence. Surely you would think that there would have been considerable resources applied to checking on the small charity to which you were considering granting a huge sum like $444m.

If you thought that, again you would be disappointed. Again, from the horse’s mouth, so to speak, Marsden tells us that neither she nor anyone else at the foundation was contacted during any due-diligence investigation.

You just can’t give taxpayers’ funds away in such a cavalier fashion. If the commonwealth auditor-general is reviewing this farce, then he needs to look no further than the pathetic attempt at the due diligence.

Marsden’s attempts to put us at ease with the process are falling on many a deaf ear. Her claim that the "chairman’s panel and our corporate partners have no role in selecting projects" rings hollow.

It must be a very odd set-up if the board is unable to oversee the process of granting money. It must have the power to overrule the process if it finds any aspect of it unsatisfactory. It is not hard to understand how nervous the foundation is about the power of its board. Names such as BHP and Rio Tinto will frighten any friends of the reef given the many attempts over the years to mine this wonder of the world.

To think Malcolm Turnbull wants to hold a parliamentary inquiry into alleged bullying in a backbencher’s office but sees no need for anything like that when he presides over one of the biggest scandals in our history of maladministration says so much about our Prime Minister.

Bleaching of the Great Barrier Reef could happen every two years, report finds

Another Greenie prophecy that is bound to look absurd in the near future!  Greenies never tire of making scary prophecies even though they have yet to get one right.

We read: "The Climate Council is Australia’s leading climate change communications organisation".  That should tell you that they will never find that all is well.  People who believe in climate change never do.  Couple that with dissenting scientists like Peter Ridd getting fired and you can be sure that the "report" below is just propaganda based on cherry-picking and exaggeration.

You can tell it is propaganda by their maniacal insistence that only global temperature control will be of any benefit to the reef. They are in the grip of a reality-denying cult



THE Great Barrier Reef could be hit with catastrophic bleaching every two years unless more is done to limit climate change.

A new report from the Climate Council reveals coral bleaching is now happening on average every six years, compared to once every 27 years back in the 1980s.

Based on current rising greenhouse gas levels, bleaching will happen every two years by 2034.

In the report released today Lethal Consequences: Climate Change Impacts on the Great Barrier Reef, the Climate Council says the current rate of bleaching is not sustainable because it will continuously set back recovery of the reef.

At the same time, the reef will also need to deal with other threats caused by climate change — such as ocean acidification and tropical cyclones.

The report found average coral cover in the northern section of the reef is at its lowest point on record, and coral cover in the central section of the reef declined from 22 per cent in

2016 to 14 per cent in 2018, largely due to the 2017 bleaching event.

It said the damage to the reef may be irreversible and it has already resulted in a drop in the diversity of fish species and in the number of juvenile fish settling on the reef.

"Intensifying marine heatwaves around the world are now occurring more often, lasting longer and are more intense than ever before," Climate Councillor and ecologist Professor Lesley Hughes said.

Professor Hughes said the bleaching events in 2016 and 2017 resulted in mass coral mortality, with the 2016 bleaching event at least 175 times more likely to occur due to intensifying climate change.

"Unless drastic action is taken, extreme coral bleaching will be the new normal by the 2030s. We will see extreme ocean temperatures, similar to those that led to these bleaching events possibly occurring every two years, which will effectively sign the death certificate for the world’s largest natural living wonder that is the Great Barrier Reef," she said.

The report makes clear that doing things like improving water quality are not the solution.

It says that unless "deep cuts in greenhouse gas emissions are made as a matter of urgency — the reef stands little chance no matter what measures are taken to enhance its resilience".

In particular, global warming must be limited to 1.5 degrees above pre-industrial levels.

"A 2C rise in average global temperature will almost certainly mean the collapse of warm water tropical reefs around the world," the report states.

"The decisions and actions that we take today to reduce greenhouse pollution will have a critical effect on the long-term survival of the iconic Great Barrier Reef."

Climate Council acting chief executive officer Dr Martin Rice said the future of coral reefs around the world depended on nations including Australia doing their part to tackle climate change.

No room for differing views

“What happened to me has a massive chilling effect on debate,” says physics professor Peter Ridd, who was sacked by James Cook University last week after saying other scientists, including former colleagues, have exaggerated the dangers to the Great Barrier Reef.

“Any scientist who might agree with me on the reef will just keep their mouth shut, it’s just too risky.”

The well-published professor in coastal oceanography, reef systems and peer review, and a former head of JCU’s school of physics, allegedly has “engaged in serious misconduct, including denigrating the university and its employees, and not acting in the best interests of the university”, according to vice-chancellor Sandra Harding in the letter terminating his employment.

The sacking stems from comments the 29-year JCU veteran made on Sky News that “science is coming out not properly checked, tested or replicated” and those who claim problems with the reef are too “emotionally attached to their subject” — views already aired in his chapter in the book Climate Change: The Facts 2017, produced by the Institute of Public Affairs. Ridd’s academic freedom supposedly has fallen foul of the institution’s code of conduct. A disturbing pattern is emerging on Australia campuses. The JCU experience is typical of the breakdown of free intellectual inquiry at our universities; of debate replaced by dogma.

“I’m a lefty myself, but a monoculture is always a risk, whether you’re part of it or against it,” says Bill von Hippel, acting head of psychology at the University of Queensland. “I’m very worried that the left-leaning ideology of most members of our field might skew the nature of the questions we ask and the way we interpret our findings.”

Ridd has taken his fight to the Federal Circuit Court on the grounds that termination of his employment is a breach of his contractual right to academic freedom. “We need universities to actually encourage different viewpoints so that we get argument,” he says.

Inquirer has spoken to more than a dozen Australian academics across disciplines, universities, and the political spectrum who are concerned about the suffocating monoculture that is gripping our universities, jeopardising research and teaching.

Australian University Professor Sacked for Telling-the-Truth about coral

Jennifer Marohasy

BACK in 2016, when I asked Peter Ridd if he would write a chapter for the book I was editing I could not possibly have envisaged it could contribute to the end of his thirty-year career as a university professor.

Considering that Peter enrolled at James Cook University as an undergraduate back in 1978, he has been associated with that one university for forty years.

Since Peter was fired on 2 May 2018, the university has attempted to remove all trace of this association: scrubbing him completely from their website.

But facts don’t cease to exist because they are removed from a website. The university has never challenged the veracity of Peter’s legitimate claims about the quality of much of the reef science: science on which billions of dollars of taxpayer-funded research is being squandered. These issues are not going away.

Just yesterday (Friday 18 May), Peter lodged papers in the Federal Court. He is going to fight for his job back!

If you care about the truth, science and academic freedom, please donate to help bring this important case to court.

It doesn’t matter how little or how much you donate. Just make sure you are a part of this important effort by donating to Peter’s GoFundMe campaign.

Peter deliberately choose to frame the book chapter about the replication crisis that is sweeping through science.

In this chapter – The Extraordinary Resilience of Great Barrier Reef Coral and Problems with Policy Science – Peter details the major problems with quality assurance when it comes to claims of the imminent demise of the reef.

Policy science concerning the Great Barrier Reef is almost never checked. Over the next few years, Australian governments will spend more than a billion dollars on the Great Barrier Reef; the costs to industry could far exceed this. Yet the keystone research papers have not been subject to proper scrutiny. Instead, there is a total reliance on the demonstrably inadequate peer-review process.

Ex-professor Peter Ridd has also published extensively in the scientific literature on the Great Barrier Reef, including issues with the methodology used to measure calcification rates. In the book he explains:

Like trees, which produce rings as they grow, corals set down a clearly identifiable layer of calcium carbonate skeleton each year, as they grow. The thicknesses and density of the layers can be used to infer calcification rates and are, effectively, a measure of the growth rate. Dr Glenn De’ath and colleagues from the Australian Institute of Marine Science used cores from more than 300 corals, some of which were hundreds of years old, to measure the changes in calcification during the last few hundred years. They claimed there was a precipitous decline in calcification since 1990

The LHS chart suggests a problem with coral growth rates – but the real problem is with the methodology. When corals of equivalent age are sampled, there has been no decline in growth rates at the Great Barrier Reef

However, I have two issues with their analysis. I published my concerns, and an alternative analysis, in the journal Marine Geology (Ridd et al. 2013). First, there were instrumental errors with the measurements of the coral layers. This was especially the case for the last layer at the surface of the coral, which was often measured as being much smaller than the reality. This forced an apparent drop in the average calcification for the corals that were collected in the early 2000s – falsely implying a recent calcification drop. Second, an ‘age effect’ was not acknowledged. When these two errors are accounted for, the drop in calcification rates disappear, as shown in Figure 1.2.

The problem with the ‘age effect’, mentioned above, arose because in the study De’ath and colleagues included data from corals sampled during two distinct periods and with a different focus; I will refer to these as two campaigns. The first campaign occurred mostly in the 1980s and focused on very large coral specimens, sometimes many metres across. The second campaign occurred in the early 2000s due to the increased interest in the effects of CO2. However, presumably due to cost cutting measures, instead of focusing on the original huge coral colonies, the second campaign measured smaller colonies, many just a few tens of centimetres in diameter.

In summary, the first campaign focused on large old corals, while, in contrast, the second campaign focused on small young corals. The two datasets were then spliced together, and wholly unjustifiable assumptions were implicitly made, but not stated – in particular that there is no age effect on coral growth…

Dr Juan D’Olivo Cordero from the University of Western Australia collected an entirely different dataset of coral cores from the Great Barrier Reef to determine calcification rates. This study determined that there has been a 10% increase in calcification rates since the 1940s for offshore and mid-shelf reefs, which is the location of about 99% of all the coral on the Great Barrier Reef. However, these researchers also measured a 5% decline in calcification rates of inshore corals – the approximately 1% of corals that live very close to the coast. Overall, there was an increase for most of the Great Barrier Reef, and a decrease for a small fraction of the Great Barrier Reef.

While it would seem reasonable to conclude that the results of the study by D’Olivo et al. would be reported as good news for the Great Barrier Reef, their article in the journal Coral Reefs concluded:

Our new findings nevertheless continue to raise concerns, with the inner-shelf reefs continuing to show long-term declines in calcification consistent with increased disturbance from land-based effects. In contrast, the more ‘pristine’ mid- and outer-shelf reefs appear to be undergoing a transition from increasing to decreasing rates of calcification, possibly reflecting the effects of CO2-driven climate change.

Imaginatively, this shift from ‘increasing’ to ‘decreasing’ seems to be based on an insignificant fall in the calcification rate in some of the mid-shelf reefs in the last two years of the 65-year dataset.

Why did the authors concentrate on this when their data shows that the reef is growing about 10% faster than it did in the 1940s?

James Cook university could have used the chapter as an opportunity to start a much-needed discussion about policy, funding and the critical importance of the scientific method. Instead, Peter was first censored by the University – and now he has been fired.

When I first blogged on this back in February, Peter needed to raise A$95,000 to fight the censure.

This was achieved through an extraordinary effort, backed by Anthony Watts, Joanne Nova, John Roskam and so many others.

To be clear, the university is not questioning the veracity of what ex-professor Ridd has written, but rather his right to say this publicly. In particular, the university is claiming that he has not been collegial and continues to speak-out even after he was told to desist.

New allegations have been built on the original misconduct charges that I detailed back in February. The core issue continues to be Peter’s right to keep talking – including so that he can defend himself.

In particular, the university objects to the original GoFundMe campaign (that Peter has just reopened) because it breaches claimed confidentiality provisions in Peter’s employment agreement. The university claims that Peter Ridd was not allowed to talk about their action against him. Peter disputes this.

Of course, if Peter had gone along with all of this, he would have been unable to raise funds to get legal advice – to defend himself! All of the documentation is now being made public – all of this information, and more can be found at Peter’s new website.

Together, let’s fight this! Go fund ex-professor Ridd at:

https://au.gofundme.com/peter-ridd-legal-action-fund.

The Institute of Public Affairs published Climate Change, The Facts 2017, and continues to support Peter’s right to speak the truth. For media and comment contact Evan Mulholland on 0405 140 780, or at emulholland@ipa.org.au.

Buy the book if you haven’t already: this is another way of showing your support.

The most important thing is to not be silenced, shout about this! I received an email last week: “Bought Climate Change, The Facts 2017, as requested, to support Peter Ridd. I’m not making any friends at dinner parties at the moment. Stuff ’em.”

Great Barrier grief: Coral 'cooked to death' in scorching summer heatwave

This is just an academic republication of some claims made in 2016, which were shown at the time to be greatly exaggerated.  And note below that global sea surface temperatures actually FELL during late 2016. 



So if there was a big warming event in North Queensland waters at the time it was a LOCAL event, not a global one.  So any coral damage was not caused by global warming. 

The BOM does record high temperatures in the reef area in 2016 but admits that there were several factors contributing to that.  I quote:

"The 2015–16 El NiƱo suppressed and delayed the monsoon, leading to reduced cloud cover and weakened winds this summer. Additionally, a relatively low number of summer storms occurred over the Reef. These factors led to increased surface heating and reduced mixing, resulting in substantially warmer ocean temperatures around northern Australia from December to March 2016."

And note that the BOM places the warming in early 2016, not late 2016.  Pesky!

Something else that happened in 2016 was a regional sea-level fall --which really is detrimental to coral and could alone explain any damage.

And note the announcement from late last year that bleached corals are already recovering nicely.  So no fear for them is warranted.

It's just propaganda below -- propaganda in a scholarly disguise.  I actually wonder whether they did all the surveys they claim to have done? A little bit of interpolation here and there, perhaps?  JCU has a record of dubious integrity.  Ask Peter Ridd about that



Millions of corals on the Great Barrier Reef were 'cooked' during a scorching summer in the northern region, according to scientists.

The underwater heatwave eliminated a huge number of different species of coral during a process which expelled algae after the polyps were stressed.

'When corals bleach from a heatwave, they can either survive and regain their colour slowly as the temperature drops, or they can die.

'Averaged across the whole Great Barrier Reef, we lost 30 per cent of the corals in the nine-month period between March and November 2016,' said Professor Terry Hughes from James Cook University said.

Prof Hughes who acts as the Director of the ARC Centre of Excellence for Coral Reef Studies at JCU said his team was very surprised to see a quarter of the corals die in just two to three weeks during the March heatwave.

Scientists researched the entire reef by analysing water surveys at various locations along its 2,300-kilometre distance, and combined insight with aerial data and satellite monitoring. 

Results showed 29 per cent of the 3,863 reefs which make up the world's largest reef system lost 'two-thirds or more of their corals', which dramatically impacts the ability of the reefs to maintain full ecological abilities.

'The Great Barrier Reef is certainly threatened by climate change, but it is not doomed if we deal very quickly with greenhouse gas emissions.

'Our study shows that coral reefs are already shifting radically in response to unprecedented heatwaves,' said Prof Hughes.

The team warn that if changes are not made to consider climate change it will have a huge effect on tropical reef ecosystems and, therefore, a detrimental impact on the benefits those environments provide to populations of poor nations.

Some recent notes from Lizard Island on the Great Barrier Reef

Nothing like the disaster area that the Greenies predicted

The Great Barrier Reef’s resilience has been mightily challenged and it narrowly escaped being placed on UNESCO’s list of World Heritage Sites in Danger last year. The one-two punch of Cyclone Ita in April 2014 and Cyclone Nathan just one year later left Lizard Island reeling. A coral bleaching event in the summer of 2016, resulting from a number of marine heatwaves on top of an already elevated sea temperature, dealt it a further blow.

Yet the reef displays a remarkable ability to regenerate and flourish. “There are a lot of people here studying recovery from disaster, and things are coming back after the cyclones and the bleaching,” Dr Anne Hoggett tells me during an afternoon tour of the research station.

She and her husband, Dr Lyle Vail, were appointed directors of the facility in 1990 and Anne has been working on the Lizard Island field guide, a constantly evolving resource detailing more than 7000 different ­species. “I think you could multiply that number of species by at least five, and people are discovering new ones here all the time,” she says.

Back at Clam Gardens, the cuttlefish has found a mate. Diaphanous skirts rippling, the pair frills up the side of a sherbet-coloured bommie, a ­stand-alone coral outcrop that’s been split like a watermelon by one of the recent cyclones. It looks like a tragedy, until Penny points out the crack has merely increased the surface area of the bommie and that the polyps, like busy little construction workers, are already starting to build on the ­foundations of their ancestors.

Drifting over the columns and canyons of reef we spy several ­thickets of staghorn coral, their tips a spark of pale, luminescent blue. “It’s nice to see,” Penny says, ­surfacing with a smile. “It’s encouraging.”

The ‘evil twin of global warming’ is melting starfish and other sea creatures, scientists discover

The usual rubbish.  Warming would cause the oceans to OUTGAS CO2, thus making the seas LESS acidic. Below is just an experiment which does not duplicate natural conditions.  It must have been unpleasant for the sea creatures to have acid poured on them.  Are Greenies allowed to do that?  They pretend to be zealous about looking after nature

Sea creatures are literally being eaten away and ‘dissolved’ by pollution, scientists have discovered.

It’s feared that high levels of carbon dioxide in the water could cause irreparable damage to marine ecosystems after tests found acute levels of the gas cause starfish to dissolve.

A team of marine scientists conducted a four-day experiment at Loch Sween on Scotland’s west coast to measure the response to short-term carbon dioxide exposure.

Previously, tests had focused on the effect high levels of the gas had on individual plants or animals, leaving a gap in knowledge about how whole marine ecosystems respond to sudden influxes of carbon dioxide.

When high levels of carbon dioxide enters the oceans it causes them to become more acidic due to a process that’s been described as ‘global warming’s evil twin’.

Researchers from Heriot-Watt University in Edinburgh and Glasgow University pumped water enriched with carbon dioxide into chambers placed over the coralline algal ecosystem and monitored the community’s response before, during and after exposure.

The experiment revealed acute exposure led to net dissolution, meaning calcified organisms such as the coralline algae and starfish were dissolving.

Heidi Burdett, Heriot-Watt University research fellow, said: ‘We found that there was a rapid, community-level shift to net dissolution, meaning that within that community, the skeletons of calcifying organisms like starfish and coralline algae were dissolving.

‘If you think of pulses of carbon dioxide being carried on the tide to a particular site, it’s like a flash flood of carbon dioxide.

‘Our continued monitoring of the site directly after the carbon dioxide exposure found recovery was comparably slow, which raises concern about the ability of these systems to ‘bounce back’ after repeated acute carbon dioxide events.’

World's coral reefs face new peril from beneath within decades (?)

This is just a new variation on an old fraud.  For the ocean to become more acidic it has to absorb more CO2 and thus produce carbonic acid (H2O + CO2 = H2CO3). And as CO2 levels rise, that might happen to some degree.

But according to Warmist theory higher CO2 levels will bring higher temperatures.  But higher ocean temperatures will REDUCE the carrying capacity of the oceans for CO2.  So CO2 will OUTGAS from the oceans under higher temperatures and the oceans will be LESS acidic. 

So if the galoots below really believed in global warming they would welcome it as REDUCING the threat to corals.

So there is a small potential threat to corals from higher CO2 levels but it will only eventuate if there is NO global warming. Fun?



The world's coral reefs, already enduring multiple threats from bleaching to nutrient run-off from farming, also face another challenge - this time from below.

New research, published in the journal Science on Friday, has found the sediments on which many reefs are built are 10 times more sensitive to the acidifying oceans than the living corals themselves. Some reef bases are already dissolving.

The study used underwater chambers at four sites in the Pacific and Atlantic oceans, including Heron Island in the Great Barrier Reef, and applied modelling to extrapolate results for 22 reefs in three ocean basins.

As oceans turn more acidic, the corals themselves produce less of the calcium carbonate that forms their base. Instead of growing, the reef bases start to dissolve.

"The public is less aware of the threat of ocean acidification [than warming waters]," said Brendan Eyre, a professor of biogeochemistry at the Southern Cross University and the paper's lead author.

“Coral reef sediments around the world will trend towards dissolving when seawater reaches a tipping point in acidity - which is likely to occur well before the end of the century,” he said.

At risk will be coral reef ecosystems that support tourism, fisheries and the many other human activities, he said.

The ocean's acidity has increased about 30 per cent since the start of the industrial revolution, as seas absorb about one-third of the build-up of greenhouse gases in the atmosphere.

“It is vital that we put pressure on governments globally to act in concert to lower carbon dioxide emissions as this is the only way we can stop the oceans acidifying and dissolving our reefs,” Professor Eyre said.

Rates of dissolving reef sediment will depend on their starting points, including their exposure to organic sediment. The Hawaiian reef studied is already showing signs of its sediment dissolving, with higher organic nutrient levels likely to be contributing, he said.

"Carbonate sediments in Hawaii are already net dissolving and will be strongly net dissolving by the end of the century," the paper said.

Living corals themselves appear to be able to resist the acidification process, with mechanisms and strategies to resist some of the impacts.

Still, the study said the transition of the dissolution of reef sediment "will result in the loss of material for building shallow reef habitats such as reef flats and lagoons, and associated coral cays". It is unknown if the reefs will face "catastrophic destruction" once the erosion begins, the paper said.

Over time, as coral bases begin to dissolve, they are more likely to become more vulnerable to cyclones and other threats, Professor Eyre said.

He said further study was needed to understand how reefs would be affected by temperatures, rising organic and nutrient levels and more acidic waters in combination, he said.

The impact of bleaching - such as the two mass events in the 2015-16 and 2016-17 summers on the Great Barrier Reef - would most likely accelerate the breakdown of reefs by "making more sediment and organic matter available for dissolution", the paper said.

Science or silence? My battle to question doomsayers about the Great Barrier Reef

By Professor Peter Ridd.  His university is desperate to shut him up as he tells basic scientific truth, which they  see as threatening the funding that they have bought with lies and alarmism. Ridd leads the Marine Geophysical Laboratory, James Cook University, Australia and has authored over 100 scientific papers

Around the world, people have heard about the impending extinction of the Great Barrier Reef: some 133,000 square miles of magnificent coral stretching for 1,400 miles off the northeast coast of Australia.

The reef is supposedly almost dead from the combined effects of a warming climate, nutrient pollution from Australian farms, and smothering sediment from offshore dredging.

Except that, as I have said publicly as a research scientist who has studied the reef for the past 30 years, all this most likely isn’t true.

And just for saying that – and calling into question the kind of published science that has led to the gloomy predictions – I have been served with a gag order by my university. I am now having to sue for my right to have an ordinary scientific opinion.

My emails have been searched. I was not allowed even to speak to my wife about the issue. I have been harangued by lawyers. And now I’m fighting back to assert my right to academic freedom and bring attention to the crisis of scientific truth.

The problems I am facing are part of a “replication crisis” that is sweeping through science and is now a serious topic in major science journals. In major scientific trials that attempt to reproduce the results of scientific observations and measurements, it seems that around 50 percent of recently published science is wrong, because the results can’t be replicated by others.

And if observations and measurements can’t be replicated, it isn’t really science – it is still, at best, hypothesis, or even just opinion. This is not a controversial topic anymore – science, or at least the system of checking the science we are using, is failing us.

The crisis started in biomedical areas, where pharmaceutical companies in the past decade found that up to 80 percent of university and institutional science results that they tested were wrong. It is now recognized that the problem is much more widespread than the biomedical sciences. And that is where I got into big trouble.

I have published numerous scientific papers showing that much of the “science” claiming damage to the reef is either plain wrong or greatly exaggerated. As just one example, coral growth rates that have supposedly collapsed along the reef have, if anything, increased slightly.

Reefs that are supposedly smothered by dredging sediment actually contain great coral. And mass bleaching events along the reef that supposedly serve as evidence of permanent human-caused devastation are almost certainly completely natural and even cyclical.

These allegedly major catastrophic effects that recent science says were almost unknown before the 1980s are mainly the result of a simple fact: large-scale marine science did not get started on the reef until the 1970s.

By a decade later, studies of the reef had exploded, along with the number of marine biologists doing them. What all these scientists lacked, however, was historical perspective. There are almost no records of earlier eras to compare with current conditions. Thus, for many scientists studying reef problems, the results are unprecedented, and almost always seen as catastrophic and even world-threatening.

The only problem is that it isn’t so. The Great Barrier Reef is in fact in excellent condition. It certainly goes through periods of destruction where huge areas of coral are killed from hurricanes, starfish plagues and coral bleaching. However, it largely regrows within a decade to its former glory. Some parts of the southern reef, for example, have seen a tripling of coral in six years after they were devastated by a particularly severe cyclone.

Reefs have similarities to Australian forests, which require periodic bushfires. It looks terrible after the bushfire, but the forests always regrow. The ecosystem has evolved with these cycles of death and regrowth.

The conflicting realities of the Great Barrier Reef point to a deeper problem. In science, consensus is not the same thing as truth. But consensus has come to play a controlling role in many areas of modern science. And if you go against the consensus you can suffer unpleasant consequences.

The main system of science quality control is called peer review. Nowadays, it usually takes the form of a couple of anonymous reviewing scientists having a quick check over the work of a colleague in the field.

Peer review is commonly understood as painstaking re-examination by highly qualified experts in academia that acts as a real check on mistaken work. It isn’t.  In the real world, peer review is often cursory and not always even knowledgeable. It might take reviewers only a morning to do.

Scientific results are rarely reanalyzed and experiments are not replicated. The types of checks that would be routine in private industry are just not done.

I have asked the question: Is this good enough quality control to make environmental decisions worth billions of dollars that are now adversely affecting every major industry in northeast Australia?

Our sugar industry has been told to make dramatic reductions in fertilizer application, potentially reducing productivity; our ports have dredging restrictions that threaten their productivity; scientists demand that coal mines be closed; and tourists are scared away because the reef is supposedly almost dead – not worth seeing anymore.

Last August I made this point on Sky News in Australia in promotion of a chapter I wrote in “Climate Change: The Facts 2017,” published by the Australian free market think tank the Institute of Public Affairs.

“The basic problem is that we can no longer trust the scientific organizations like the Australian Institute of Marine Science, even things like the Australian Research Council Centre of Excellence for Coral Reef Studies … the science is coming out not properly checked, tested or replicated and this is a great shame because we really need to be able to trust our scientific institutions and the fact is I do not think we can any more,” I said.

The response to these comments by my employer, James Cook University, was extraordinary. Rather than measured argument, I was hit with a charge of academic serious misconduct for not being “collegial.”

University authorities told me in August I was not allowed to mention the case or the charges to anybody – not even my wife.

Then things got worse. With assistance from the Institute of Public Affairs, I have been pushing back against the charges and the gag order – leading the university to search my official emails for examples of where I had mentioned the case to other scientists, old friends, past students and my wife.

I was then hit with 25 new allegations, mostly for just mentioning the case against me. The email search turned up nothing for which I feel ashamed. You can see for yourself.

We filed in court in November. At that point the university backed away from firing me. But university officials issued a “Final Censure” in my employment file and told me to be silent about the allegations, and not to repeat my comments about the unreliability of institutional research.

But they agreed that I could mention it to my wife, which was nice of them.

I would rather be fired than accept these conditions. We are still pursuing the matter in court.

This case may be about a single instance of alleged misconduct, but underlying it is an issue even bigger than our oceans. Ultimately, I am fighting for academic and scientific freedom, and the responsibility of universities to nurture the debate of difficult subjects without threat or intimidation.

We may indeed have a Great Barrier Reef crisis, but the science is so flawed that it is impossible to tell its actual dimensions. What we do know for certain is that we have an academic freedom crisis that threatens the true life of science and threatens to smother our failing university system.

A Coral's Biological Control of its Calcifying Medium to Favor Skeletal Growth
    
Great news for those concerned about potential future impacts of so-called ocean acidification on corals. A New Study shows they are able to continue skeletal growth under the most pessimistic of ocean acidification scenarios



Paper Reviewed: Raybaud, V., TambuttĆ©, S., Ferrier-PagĆØs, C., Reynaud, S., Venn, A.A., TambuttĆ©, Ɖ., Nival, P. and Allemand, D. 2017. Computing the carbonate chemistry of the coral calcifying medium and its response to ocean acidification. Journal of Theoretical Biology 424: 26-36.

Introducing their very intriguing study, Raybaud et al. (2017) write that "critical to determining vulnerability or resilience of reef corals to ocean acidification (OA) is a clearer understanding of the extent to which corals can control carbonate chemistry in their extracellular calcifying medium (ECM) where the calcium carbonate skeleton is produced." However, information about the coral ECM is sparse due to the difficulty of accessing it (it is located under several overlying cell layers and has a thickness varying from a few nanometers to a few micrometers).

In an effort to overcome this measurement obstacle, the team of eight researchers presented what they describe as "a novel, alternative means of indirectly assessing ECM carbonate chemistry using coral calcification rates, seawater characteristics (temperature, salinity and pH) and pH measurements of the ECM (pH(ECM))." More specifically, this involved (1) calculating coral species-specific relationships between seawater pH and pH(ECM) using pH(ECM) data from six publications on 5 different species that have measured pH(ECM) at several different levels of seawater pH, (2) calculating the aragonite saturation state (Ī©arag.(ECM)) and calcium carbonate ion concentration ([CO32-](ECM)) in the ECM from coral calcification rates previously published in 20 peer-reviewed studies and (3) using pH(ECM) and [CO32-](ECM) to calculate the ionic concentration of the other chemical parameters in the carbonate system of the ECM under current and reduced values of seawater pH. This approach yielded a number of significant findings described in the paragraphs below.

The species-specific relationships between seawater pH and pH(ECM) revealed that all five of the corals analyzed in this stage of the analysis (Desmophyllum dianthus, Cladocora caespitosa, Porites spp., Acropora spp. and Stylophora pistillata) upregulated their pH(ECM) relative to that at normal seawater pH. What is more, the degree of pH(ECM) upregulation increased as seawater pH decreased, indicating, in the words of the authors, "an active biological control of the ECM chemistry by corals."

In the second phase of their work, Raybaud et al. discovered that the Ī©arag.(ECM) values calculated from the 20 coral studies they analyzed ranged from 10.16 to 38.31 (mean of 20.41), which values were "~5 to 6-fold higher than Ī©arag. in seawater (Ī©arag.(SW)), which favors the aragonite precipitation of coral skeleton in the ECM." They also note that "Ī©arag.(ECM) was higher for cold-water corals, which have slower growth rates than for tropical ones," adding that "the greater ability of certain cold-water coral species to raise their Ī©arag.(ECM) may be an adaptive mechanism, as recently suggested by Hendriks and colleagues (Hendriks et al., 2015), enabling these organisms to grow in seawater that is close to under-saturation with respect to aragonite (Ī©arag.(SW) ~1; (Thresher et al., 2011))."

Finally, with respect to the third phase of their study -- assessing other chemical parameters in the carbonate system of the ECM -- the authors report that (1) dissolved inorganic carbon and total alkalinity were approximately 3 times higher in the ECM than in seawater at normal pH, (2) carbonate concentration was 5.9 times higher, (3) bicarbonate ions were 2.1 times more concentrated and (4) hydroxide 2.3 fold higher, which observations clearly indicate the ability of corals to biologically mediate the process of calcification in the ECM under present-day seawater pH conditions. But will they continue to do so in the future under projections of pH decline?

To answer this question, Raybaud et al. utilized data from a long-term laboratory experiment performed on the tropical coral Stylophora pistillata in order to assess how coral ECM chemistry might change due to ocean acidification. The results are presented in the figure below, which illustrate the impact of ocean acidification on calcification rates and various ECM chemical characteristics of S. pistillata coral colonies exposed to normal (8.0) and reduced (7.8, 7.4 and 7.2) seawater pH levels for a period of one year.

As indicated there, Ī©arag.(ECM) and [CO32-](ECM) exhibited only small reductions under increasing levels of ocean acidification compared to corresponding changes that occurred in normal seawater. For instance, although Ī©arag. of the seawater decreased by 78% (from 3.17 to 0.69, as denoted by the blue horizontal lines in Figure 1e), when the pH declined from 8 to 7.2, Ī©arag. and [CO32-] of the ECM each fell by a much smaller 9 percent to values that were 22.4 times higher than those reported in seawater outside the ECM in the most severe ocean acidification treatment (i.e., pH of 7.2). Consequently, the team of researchers write that "the ECM in S. pistillata under ocean acidification has a higher buffer capacity than under current pH," evidenced by the increasing difference between Ī©arag.(ECM) and Ī©arag.(SW) as the seawater pH treatments decline from 8.0 to 7.2 (see the vertical arrows and orange numbers associated with Ī©arag. under the different pH treatments shown in Figure 1e).

In light of all of the above facts, Raybaud et al. conclude their results clearly show that "despite unfavorable Ī©arag.(SW) [down to a seawater pH of 7.2], corals are able to maintain Ī©arag.(ECM) sufficiently high to allow calcification to proceed," as "the biological regulation of ECM chemistry keeps Ī©arag.(ECM) almost constant" under ocean acidification scenarios far beyond those likely to ever occur. And that is incredibly wonderful news for those concerned about potential future impacts of so-called ocean acidification on corals.

Critic of coral reef alarmism Raised $99K To Defend Freedom Of Speech In Just 48 Hours

Last week Professor Peter Ridd launched a GoFundMe to fundraise for his legal costs against James Cook University in the Federal Court.

Amazingly, after a public appeal, he has reached the required $95,000 to cover his defence in just 48 hours.

Institute of Public Affairs Executive Director, John Roskam, spoke to Alan Jones on 2GB this morning about Professor Ridd’s case.

In August last year Professor Ridd was interviewed by Alan Jones on Sky News about his chapter in a book Climate Change: The Facts 2017 published by the Institute of Public Affairs.  In his chapter, The Extraordinary Resilience of Great Barrier Reef Corals, and Problems with Policy Science, Professor Ridd wrote:

"Policy science concerning the Great Barrier Reef is almost never checked. Over the next few years, Australian government will spend more than a billion dollars on the Great Barrier Reef; the costs to industry could far exceed this. Yet the keystone research papers have not been subject to proper scrutiny. Instead, there is a total reliance on the demonstrably inadequate peer review process."

Professor Ridd said on Sky News:

"The basic problem is that we can no longer trust the scientific organisations like the Australian Institute of Marine Science, even things like the ARC Centre of Excellence for Coral Reef Studies – a lot of this is stuff is coming out, the science is coming out not properly checked, tested or replicated and this is a great shame because we really need to be able to trust our scientific institutions and the fact is I do not think we can any more…

…I think that most of the scientists who are pushing out this stuff they genuinely believe that there are problems with the reef, I just don’t think they’re very objective about the science they do, I think they’re emotionally attached to their subject and you know you can’t blame them, the reef is a beautiful thing."

JCU claimed that Professor Ridd’s comments denigrated the university and the university directed him to make no future such comments.

Thanks to the contributions of many IPA members and supporters of Professor Ridd, he is able to defend scientific integrity and academic freedom in the Federal Court.

Great Barrier Reef in 'deep trouble' as climate, other threats mount: official

More lying Greenie propaganda.  Their claims about bleaching in 2015/2016 were not and could not be verified.  When Prof. Ridd pointed that out, what did they do?  Present evidence of verification?  No way.  They sued Peter Ridd for letting the cat out of the bag.  What frauds!  What jerks!  They just love the funding they get for their lies.  They've just got $60 million from the Feds

The Great Barrier Reef is in "deep trouble" as climate change and other threats mount, hindering the ability of corals to rebound from natural events, a senior scientist with the reef's Marine Park Authority said.

Unprecedented back-to-back mass coral bleachings resulted in 29 per cent of the shallow water corals dying in the summer of 2015-16 and a further 20 per cent last summer, David Wachenfeld, director of recovery at the authority, said.

Fortunately, "there's no prediction of substantial mass bleachings at this point" for this summer. Still, February - typically the worst month for heat stress on corals - "is going to be a slightly nervous month" for scientists, Dr Wachenfeld said.

The roughly 50-per cent death rate for the corals excludes damage done last March by Cyclone Debbie, which tore into the northern end of the southern section of the Great Barrier Reef - an area largely spared from the bleaching events.

While corals have a natural ability to bounce back, the increasing frequency and severity of extreme weather made recovery harder.

"[E]very time we get impacts on the reef, they are slightly or a lot worse than previous impacts," Dr Wachenfeld told Fairfax Media. "And the question is, as we keep seeing bigger impacts, will the reef continue to be as resilient as it has been in the past?"

How climate change will affect the Great Barrier Reef and other parts of Australia will feature at a week-long gathering of senior scientists in Sydney for the first Australian/New Zealand Climate Forum held in seven years.

Terry Hughes, Director of the ARC Centre of Excellence for Coral Reef Studies and one of the speakers at the event, said scientists were in "uncharted territory" when it came to predicting how fast the reef can recover.

"Normally, after a cyclone, it takes 10-15 years for the fastest-growing species to bounce back," Professor Hughes said.

"Optimistically, 50 per cent mortality after the two recent heatwaves means the glass is still half full," he said. "The survivors ... are tougher than the corals that died - there is about a billion of them, and they are reproducing."

Dr Wachenfeld said tackling other stressors on corals, including from nutrient run-off from farms and the latest big outbreak of crown-of-thorns starfish, were important local efforts to help corals rebound.

"That's the way to give the reef the best chance to survive the global threat of climate change," he said.

"The reef is still a dynamic, vibrant, awesome place," Dr Wachenfeld said. "But it's in deep trouble, and at the moment, it's not heading in the right direction."

Australia: Greenies trying to gag honest scientist

Marine scientist commented on their "unvalidated" public pronouncements about catastrophic damage to the Great Barrier Reef.  The reef is now back to normal so he was proved right.

Marine scientist Peter Ridd has refused to accept a formal censure and gag order from James Cook University and expanded his Federal Court action to defend academic freedoms and free speech.

A revised statement of claim alleges JCU trawled through private email conversations in a bid to bolster its misconduct case against him.

JCU had found Professor Ridd guilty of “serious misconduct”, ­including denigrating a co-worker, denigrating the university, breaching confidentiality, publishing information outside of the university and disregarding his obligations as an employee. [i.e. He told the truth]

Professor Ridd has asked the Federal Court to overturn the university ruling and confirm his right not to be silenced.

In the revised statement of claim, Professor Ridd has dropped an earlier claim of conflict of interest against JCU vice-chancellor Sandra Harding, but has alleged other senior staff had been biased and had not acted fairly or in good faith.

Professor Ridd’s Federal Court action is seen as a test of academic freedom and free speech, and has been supported by the Institute of Public Affairs.

Professor Ridd said he would seek public donations to continue the fight against JCU. He first took court action in November in a bid to stop a JCU disciplinary process against him for comments he made to Sky News presenter Alan Jones.

The university said by expressing concerns about the quality of some reef science, Professor Ridd had not acted in a “collegiate” manner.

Professor Ridd told Sky News: “The basic problem is that we can no longer trust the scientific ­organisations like the Australian Institute of Marine Science, even things like the ARC Centre of Excellence for Coral Reef Studies.”

He said a lot of the science was not properly checked, tested or replicated and “this is a great shame because we really need to be able to trust our scientific institutions and the fact is I do not think we can any more”.

A JCU spokesman said the university’s lawyers had invited Professor Ridd to discontinue his proceedings. “(He) has amended his proceedings. His decision to do so is a matter for him,” he said.

“The university intends to vigorously defend those proceedings (but) as these matters are before the courts, JCU will not comment further.”

Lawyers for JCU wrote to Professor Ridd on November 28 confirming the university had determined he had engaged in “serious misconduct” and issued him with a “final censure”.

“The disciplinary process and all information gathered and recorded in relation to the disciplinary process (including the allegations, letters, your client’s responses and the outcome of the disciplinary process) is confidential pursuant to clause 54.1.5 of the university enterprise agreement,” the JCU lawyers said.

Professor Ridd has subsequently published his concerns about the quality of reef science in a peer-reviewed journal. He said he was determined to speak freely about his treatment “even though it will go against explicit directions by JCU not to”.

“This is as much a case about free speech as it is about quality of science,” he said.

The Never-ending Battles of the Coral Sea

Viv Forbes

For at least 50 years Australian taxpayers and other innocents have supported a parasitic industry in academia, bureaucracy, law, media and the tax-exempt Green Alarm “Charities”, all studying, regulating, inspecting and writing about yet another “imminent threat to Queensland’s Great Barrier Reef.”

It has become the never-ending battle of the Coral Sea.

The threats change, but there is always a doomsday forecast – Crown-of-Thorns, oil drilling, fishing, cane farming, coastal shipping, global warming, ocean acidity, coral bleaching, port dredging, chemical and fertiliser runoff, coal transport, river sediments, loss of world heritage status etc. Every recycled scare, magnified by the media and parroted by politicians, generates more income for the alarm industry, usually at the expense of taxpayers, consumers or local industries.

The reality is that sea creatures would starve in pure water – all marine life needs nutrients, salts and minerals. These come from other life forms, from decomposing rocks and organic matter carried to the sea by rivers, from dissolving atmospheric gases, or from delta and shelf sediments stirred up by floods, cyclones, dredging or coastal shipping. No one supports over-use of toxic man-made chemicals, but well-run cane, cattle and coal companies can co-exist with corals.

Corals first appeared 500 million years ago and have proven to be one of Earth’s great survivors. They outlasted the Carboniferous Forests, the Permian and Cretaceous extinctions, the dinosaurs, the mammoths, the Neanderthals and the Pleistocene cycles of ice age and warming. They thrive in warm tropical water, cluster around hot volcanic fumaroles and survive massive petroleum spills, natural oil seeps, tidal waves and volcanic dust. They have even recolonised the Montebello Island waters devastated by atomic bomb testing in the 1950’s.

The ENSO oscillation of blobs of warm Pacific water which caused recent coral bleaching can be identified in historical records for at least 400 years. Corals have survived El Nino warmings for thousands of years and they will probably outlast Homo Alarmism as Earth proceeds into the next glacial epoch.

Corals do not rely on computer models of global temperature to advise them – they read the sea level thermometer which falls and rises as the great ice sheets come and go.

In the warming phase like the one just ending, ice melts, sea levels rise and the reef that houses the corals may get drowned. Corals have two choices – build their reef higher or just float south/inshore and build a new reef (like the Great Barrier Reef) in shallower, cooler water. When islands sink beneath rising oceans, corals may build their own coral atolls as fast as the water rises.

Then when the cold era returns, ice sheets grow, sea levels fall, and the warm era coral reefs (like the Great Barrier Reef) get stranded on the new beaches and coastal plains. Usually the process is slow enough to allow the coral polyps to float into deeper warmer water closer to the equator and build another reef.

This eminently sensible policy of “move when you have to” has proved a successful survival policy for the corals for 500 million years.

Humans should copy the corals – “forget the computer climate models but watch real data like actual sea levels and . . . move when you have to.”

Australia: New funding for the Great Barrier Reef

This is in response to Greenie claims that the GBR is "dying".  The reef has been there for millennia but Greenies talked up some recent changes as if they were catastrophic and final.  As is now clear even to a Greenie, the reef "fixes" itself.  It has rebounded from the small but highly exaggerated degree of damage that it suffered.

Dead coral revives when the stressor -- in this case a temporary sea level fall -- goes away.  To Greenies, of course, coral deaths are caused by Global Warming. 

The new money seems to be reasonably allocated even if the need for it was built on false pretences


THE number of crown-of-thorns starfish control vessels will be more than doubled under a new $60 million Great Barrier Reef funding suite.

Prime Minister Malcolm Turnbull will unveil the package in Townsville today as he continues the North Queensland tour that began in Cairns yesterday.

The Federal Government will spend $10.4 million for what Mr Turnbull labelled an “all-out assault on coral-eating crown-of-thorns starfish” to increase the number of culling ships from three to eight.

Another $36.6 million will go towards measures to reduce run-off pollution entering the reef, giving farmers incentives to cut down soil erosion, improve nutrient management, and restoring coastal and riparian vegetation in reef catchments.

“This $60 million funding boost over 18 months will set in motion a major research and development program for coral reef restoration,” Mr Turnbull said.

“For the first time The Commonwealth will bring together key agencies to explore ways the reef can best adapt to the changing environment to protect it for decades to come.

“By supporting the development of innovative new reef technologies we are also helping to cement Australia’s international reputation as a strong innovation-driven economy.”

The Australian Institute of Marine Science and CSIRO will share in $6 million to scope and design the program to develop heat-tolerant coralswith a focus on leveraging private investment.

Mr Turnbull said $4.9 million would be spent to boost the number of field officers protecting the reef and the 64,000 jobs that rely on it.

“It is a vibrant, resilient ecosystem and one of the best-managed coral reef ecosystems in the world,” he said.

“While it is facing increasing threats we intend to remain leaders in reef management.

“The specific science focus of the R & D funding is part of the government’s broader focus on science, innovation and jobs and the central role they will play now and into the future.

“Innovation and science are key to future employment opportunities for Australians.”

Despite global warming, some reefs are flourishing, and you can see it in 3D

Maybe it’s not the end of the world for corals after all.

That’s one of the surprising findings of a new project called the 100 Island Challenge, led by two scientists at the Scripps Institution of Oceanography in San Diego.

Jennifer Smith, Stuart Sandin and their team from Scripps are studying the changes taking place on 100 coral reef systems around the world. What they have found offers a surprising, and hopeful, glimpse of the current state of coral reefs.

“We’ve seen evidence of health pretty much everywhere,” says Sandin. “This isn’t saying that every reef is thriving, and every reef has stayed immune to climate change. But what we’re seeing is that after a reef dies, organisms grow.” Call it the Jurassic Park effect: life finds a way.

While they acknowledge that some reef systems like the Great Barrier Reef in Australia have suffered tremendously from recent warming events, other reefs seem to be thriving.

“We were inspired by some observations that we had about seeing coral reefs in far flung places that showed signs of resilience, that showed bounty, that showed wonder,” says Sandin. “And these observations that we had were somewhat in contrast to some of the news reports of doom and gloom, of loss.”

If you don’t believe it, take a look at the video above, which the team has assembled as part of the 100 Island Challenge. In vivid 3D, corals bulge with life, exhibiting vibrant hues that stand in stark contradiction to the pale skeletons left behind after coral bleaching events that have ravaged other reefs.

The videos themselves are an astonishing and important part of the project. Although the corals look computer generated, the videos represent actual reef systems shot with off the shelf DSLR cameras. They are assembled from as many as 4000 photographs, shot by divers who swim lawnmower patterns over the reef, snapping a picture every second. The images are then run through a software process called photogrammetry, which stitches the images together into a 3-dimensional whole, allowing the viewer to glide across the reef with resolution down to one centimeter.

The team has shot over 70 reefs so far, in places like Hawaii, the Marianas, the Federated States of Micronesia, Palau, Tonga, and French Polynesia. This year, they will visit the Marshall Islands, the Republic of Kiribati and several islands across the Caribbean.

They plan to return to each one after 2-3 years to repeat the process. The idea is to gain a fine-grained understanding of the changes that are taking place over time on the reefs, and to do so without harming the coral. It is the most detailed study of its kind on the planet, and it’s providing data the likes of which has never been collected before.

“Now we’re able to do a single dive on a reef, capture thousands of images, bring them back home, recreate that reef in the lab and then spend hundreds of hours extracting data out of that one dive, whereas normally that would have taken hundreds of hours underwater to collect the same data,” says Smith.

Although they have not yet determined how the reefs are changing over time, perhaps the most surprising results they have seen reveal how well many reef systems are doing, even in places facing human impact. Jamaica, for example, has long been held out as a case study for coral loss. But the team visited last year and came away surprised.

“You can see these little colonies of pretty much every species of Caribbean coral alive, growing slowly,” says Sandin.

The team is already taking the study into other interactive realms, with plans to create virtual reality tours of the reefs, adding sound and expanding into 4D by adding the dimension of time into the experience. They believe that the images will become a valuable baseline for understanding the changes, both good and bad, that are taking place on the planet.

“These models are essentially a living library of reefs that will essentially be an opportunity to take a time machine into the past 20 years from now,” says Sandin.

The inconvenient truth is that catastrophists are wrong

In a hurried piece in Fairfax publications, the Climate Council of Australia’s Will Steffen throws hot water on any misconceptions that may have been drawn from abnormal snowfalls in Britain, Switzerland and Japan, the record-breaking cold snap in Canada and the US, and the expansion of the East Antarctic Ice Sheet.

He says: “Terms like ‘global warming’ and the mental images they trigger can be misleading when people attempt to understand what is happening to the climate. A far better term is ‘climate disruption’, which captures the real nature of the vast array of changes, many of them abrupt and unexpected, that are occurring.”

So fire and ice, it’s to be expected.

Of course you won’t be surprised to learn Steffen claims “the climate disruption we are increasingly experiencing is not natural. It is caused by the heat-trapping gases we humans are pouring into the atmosphere primarily by the burning of coal, oil and gas.”

On the day Steffen’s opinion piece appeared, this newspaper republished Matt Ridley’s article in The Times claiming “the Earth is very slowly slipping back into a proper ice age”. This confirms research by Henrik Svensmark, Australia’s David Evans and others, who correlated low solar activity (fewer sunspots) and increased cloud cover (as modulated by cosmic rays), with a cooling climate.

Indeed, last year scientists submitted 120 papers linking historical and modern climate change to variations in solar activity.

Steffen wasn’t among them. He says: “Whole ecosystems are succumbing to (human-induced) climate disruption. In 2016 unusually dry and hot conditions triggered massive fires in Tasmania’s World Heritage forests, while ocean circulation patterns have moved ­unprecedented underwater heatwaves around the world, driving the tragic coral bleaching of the Great Barrier Reef.’’

Yet the chairman of the Great Barrier Reef Marine Park Authority, Russell Reichelt, dismisses many of the claims that he says “misrepresent the extent and impact of coral bleaching on the Great Barrier Reef.”

Peter Ridd from James Cook University goes further, saying: “We can no longer trust the scientific organisations like the ARC (Australian Research Council) Centre of Excellence for Coral Reef Studies. The science is coming out not properly checked, tested or replicated, and this is a great shame.”

Steffen’s work could fit this description. He spends much time pushing eco-catastrophism. “Climate disruption” he says “brings growing risks of large-scale migration and conflict as people, particularly the most vulnerable, are forced to deal with increasingly difficult conditions where they live. Some security analysts warn that climate disruption will dwarf terrorism and other conventional threats if present trends continue or worsen.

“Had enough of climate disruption? Then let’s leave our 20th-century thinking behind and get on with the job of rapidly building innovative, clever, carbon-neutral 21st-century societies.”

But Ridley questions the influence of carbon dioxide. He reminds us that: “In 1895 the Swede, Svante Arrhenius, one of the scientists who first championed the greenhouse theory, suggested that the ice retreated because carbon dioxide levels rose, and advanced because they fell. If this was true, then industrial emissions could head off the next ice age. There is indeed a correlation in the ice cores between temperature and carbon dioxide, but inconveniently it is the wrong way round: carbon dioxide follows rather than leads temperature downward when the ice returns.”

But where would manmade global warming “science” be if it relied on just facts? For decades, climate science has been plagued by scandals, deceit and the confessions of whistleblowers.

Penrith’s hyped recording is not new. Scientist and long-time BOM critic Jennifer Marohasy has been calling for an audit and urging Energy and Environment Minister Josh Frydenberg “to inform the World Meteorological Organisation that the temperatures recorded by our bureau are not consistent with calibration, nor any international standard”, and, to “direct the bureau to desist from announcing new record hot days”.

Still, institutionalised data bias is a handy default for radical-left eco-catastrophists who have a tendency to extract worst-case scenarios from every weather event.

But despite their best efforts, in the public’s eyes their story is wearing thin. There have been too many false predictions and unwarranted alarmism. People are wising up to the reality that climate science has become an unfalsifiable ideology and resent having their moral conscience questioned should they disagree.

If Ridley is right and the earth is slowly slipping back into a proper ice age, it will be literally cold comfort, not to mention lethal, to keep passing it off as climate disruption.

To survive such an event, our successors will need a plentiful supply of cheap, reliable energy, impossible given today’s intelligentsia’s religious objection to low-cost fossil and nuclear fuels.

It’s not carbon dioxide that threatens us with extinction but blind ideology dressed up as science.

The End of the Ocean Acidification Scare for Corals
    
Paper Reviewed: McCulloch, M.T., D'Olivo, J.P., Falter, J., Holcomb, M. and Trotter, J.A. 2017. Coral calcification in a changing world and the interactive dynamics of pH and DIC upregulation. Nature Communications 8: 15686, DOI:10.1038/ncomms15686.

The global increase in the atmosphere's CO2 content has been hypothesized to possess the potential to harm coral reefs directly. By inducing changes in ocean water chemistry that can lead to reductions in the calcium carbonate saturation state of seawater (Ųø), it has been predicted that elevated levels of atmospheric CO2 may reduce rates of coral calcification, possibly leading to slower-growing -- and, therefore, weaker -- coral skeletons, and in some cases even death. Such projections, however, often fail to account for the fact that coral calcification is a biologically mediated process, and that out in the real world, living organisms tend to find a way to meet and overcome the many challenges they face, and coral calcification in response to ocean acidification is no exception, as evidenced by findings published in the recent analysis of McCulloch et al. (2017).

Writing in the journal Nature Communications, this team of five researchers developed geochemical proxies (Ł†11B and B/Ca) from Porites corals located on (1) Davis Reef, a mid-shelf reef located east-northeast of Townsville, Queensland, Australia in the central Great Barrier Reef, and (2) Coral Bay, which is part of the Ningaloo Reef coastal fringing system of Western Australia, in order to obtain seasonal records of dissolved inorganic carbon (DIC) and pH of the corals' calcifying fluid (cf) at these locations for the period 2007-2012. And what did those records reveal?

As shown in the figure below, coral colonies from both reef locations "exhibit strong seasonal changes in pHcf, from ~8.3 during summer to ~8.5 during winter," which "represents an elevation in pHcf relative to ambient seawater of ~0.4 pH units together with a relatively large seasonal range in pHcf of ~0.2 units." These observations, in the words of McCulloch et al., "are in stark contrast to the far more muted changes based on laboratory-controlled experiments" (as shown in the dashed black line on the figure), which laboratory-based values are "an order of magnitude smaller than those actually observed in reef environments."

With respect to DICcf (also depicted in Figure 1), McCulloch et al. report that the "highest DICcf (~ x 3.2 seawater) is found during summer, consistent with thermal/light enhancement of metabolically (zooxanthellae) derived carbon, while the highest pHcf (~8.5) occurs in winter during periods of low DICcf (~ x 2 seawater)."

The proxy records also revealed that coral DICcf was inversely related (r2 ~ 0.9) to pHcf. Commenting on this relationship, the marine scientists say it "indicate[s] that the coral is actively maintaining both high (~x 4 to x 6 seawater) and relatively stable (within ± 10% of mean) levels of elevated Ųøcf year-round." Or, as they explain it another way, "we have now identified the key functional characteristics of chemically controlled calcification in reef-building coral. The seasonally varying supply of summer-enhanced metabolic DICcf is accompanied by dynamic out-of-phase upregulation of coral pHcf. These parameters acting together maintain elevated but near-constant levels of carbonate saturation state (Ųøcf) of the coral's calcifying fluid, the key driver of calcification."

The implications of the above findings are enormous, for they reveal that "pHcf upregulation occurs largely independent of changes in seawater carbonate chemistry, and hence ocean acidification," demonstrating "the ability of the coral to 'control' what is arguably one of its most fundamental physiological processes, the growth of its skeleton within which it lives." Furthermore, McCulloch et al. say their work presents "major ramifications for the interpretation of the large number of experiments that have reported a strong sensitivity of coral calcification to increasing ocean acidification," explaining that "an inherent limitation of many of these experiments is that they were generally conducted under conditions of fixed seawater pHsw and/or temperature, light, nutrients, and little water motion, hence conditions that are not conducive to reproducing the natural interactive effects between pHcf and DICcf that we have documented here." Given as much, they conclude that "since the interactive dynamics of pHcf and DICcf upregulation do not appear to be properly simulated under the short-term conditions generally imposed by such artificial experiments, the relevance of their commonly reported finding of reduced coral calcification with reduced seawater pH must now be questioned."

And so it appears that alarmist claims of near-future coral reef dissolution, courtesy of the ever-hyped ocean acidification hypothesis, have themselves dissolved away thanks to the seminal work of McCulloch et al. Clearly, the world's corals are much more resilient to changes in their environment than acidification alarmists have claimed them to be.
