Greenies do something positive


Ecological “arks” will be created in the Great Barrier Reef under a new Federal Government funded program that for the first time links island health as critical to saving the coral.

Environment Minister Sussan Ley will today announce $5.5 million for a new island restoration program, starting with Morris Island off Cape York.

She said Lady Elliot Island on the reef’s southern border was the first regeneration project ever attempted at scale and its success could be replicated elsewhere.

“There are 1050 islands along the reef ranging from the pristine to former mine sites, disused tourism destinations and those that have been damaged by introduced pest species,” she said.

“As part of the Reef Islands initiative, Dr Kathy Townsend of Sunshine Coast University is leading new ‘leaf to reef’ research that follows the nutrient trail between islands and its importance to corals and marine life, as well as researching the importance of Lady Elliot’s reefs as a biodiversity ark in the region.”

Reef manager for the marine park authority Mark Read said overseas views particularly under-appreciated the complexity of the issue.

“For context the world heritage area is 348,000 square kilometres; it’s bigger than Italy, bigger than Japan and can sit Victoria and Tasmania within its boundaries. It stretches over 2000km and at its widest point is 250km, it’s 1050 islands, 3000 reefs – so trying to categorise that whole system within a single category, ultimately it fails and doesn’t do the system justice,” he said.

Lady Elliot Island is a genesis of what the Federal Government yesterday branded an “ecological ark” carrying the essential ingredients to rehabilitate the in-crisis reef, critically affected by natural and man-made climate change.

Gash and a dedicated team of scientists, backed by a string of Federal Government funded initiatives, are in part driven by a sketch discovered in archives drawn from a sailor aboard HMS Fly in 1843 of what the island sanctuary looked like then and could again.

“So many people say ‘oh but it’s hopeless, there is nothing we can do and it’s all going to die’ and I hate hearing that, it’s never hopeless,” Island custodian Gash said as he looks out over the turquoise waters on the southern point of the reef, 80km from the Queensland mainland.

In 1973 Lady Elliot Island was a dead 42-hectare coral atoll that after almost a century of mining for guano fertiliser was left barren, with no bird or sea life.

Now it boasts more than 1200 species of marine life including turtles and manta rays, whole forests of native Pisonia trees and grasses and the second highest diversity of breeding birds of any feature in the Great Barrier Reef after Raine Island on the reef’s northernmost tip.

Environment Minister Sussan Ley visited Lady Elliot this week to see first-hand the spectacular restoration result which she now hoped will be replicated elsewhere along the reef island chain starting with Morris Island, under a new $5.5 million investment.

Great Barrier Reef Foundation managing director Anna Marsden said without a doubt there were “dark days” ahead for the climate but Lady Elliot was a shining light in what could be achieved within our life times.

“The idea is these arks, these climate refuges, will carry the reef forward,” she said. “The habitat will be able to be the ones to go, before the dark days, then when the world gets its act together and the balance restores these are the places that will reopen the doors and repopulate.”

World renowned marine biologist Dr Kathy Townsend said the correlation between land life and reef marine life was now only being understood.

“The connection between coral cays and the island has been undervalued,” she said.

“The current dogma is where these coral cays are getting their nutrients but new research is showing these coral cays are creating nutrients for the reef in a balanced way. It’s not a dump but a pumping action … it’s like growing an island. Without healthy islands you wouldn’t have the same level of growth and biodiversity you see around the reef.”

She said there had been a 125 per cent increase in turtle habitat and they again were the primary herbivore about Lady Elliot which was keeping coral killing grasses down.

Scientists Discover Coral Reefs Recovered Quickly After Bleaching


It was a depressing if expected inevitability when Western Australia’s Rowley Shoals showed the first signs of mass coral bleaching earlier this year, but a follow-up survey has found a remarkable recovery looks likely to preserve the reef’s near-pristine health — at least for now.

Tom Holmes, the marine monitoring coordinator at the WA Department of Biodiversity, Conservation, and Attractions, said that while his team was still processing the data, it appeared the coral had pulled off an “amazing” return towards health over the past six months.

“We were expecting to see widespread mortality, and we just didn’t see it … which is a really amazing thing,” Dr. Holmes said.

The survey was a follow-up to one conducted in April that found as much as 60 percent of corals on some Rowley Shoals reefs had bleached after the most widespread marine heatwave since reliable satellite monitoring began in 1993.

It has long been known that high sea temperatures cause coral bleaching which can kill coral — as seen by the devastation of the Great Barrier Reef off the Queensland coast — but what is less well known is that bleached corals do not die immediately.

“So when a coral bleaches, it’s actually just a sign of initial stress,” Dr. Holmes said.

However, corals rely on these microscopic algae as a food source and cannot survive for long without them.

“If that stress continues for a long time and those corals remain white, then it can lead to mortality,” Dr. Holmes said.

“But there are some cases of bleaching around the world where … that stress hasn’t continued for a long time, and the corals have been able to take that alga back in from the water.”

Dr. Holmes believes that the vital time gap between bleaching and dying created a chance for the reefs to recover at the Rowley Shoals, a chain of three coral atolls 300 kilometers off Broome on the edge of Australia’s continental shelf.

In the case of Peter Ridd, we’ll soon learn whether academic freedom matters


<i>Prof. Ridd was critical of alarmist utterances about the Barrier Reef coming from his university colleagues</i>

This week there were whoops of delight from Republicans over the appointment of conservative lawyer Amy Coney Barrett to the US Supreme Court. It will, they say, buttress democracy for decades to come. The Democrats were inconsolable, marking the rushed appointment as the end of democracy. The divide is fundamental: is it the role of America’s highest court to interpret law in humble deference to what the law says, or to change the law to suit social ­engineers who have grown ­impatient with the democratic process?

Everyone agrees on one thing: judges on the US Supreme Court can alter the country in profound ways.

By the way, two new judges were appointed to Australia’s High Court this week, although few will know their names. For the record, Simon Steward from Melbourne and Jacqueline Gleeson from Sydney, both former Federal Court judges and both in their early 50s, will serve long stints on our most influential court until they reach the mandatory retirement age of 70. Steward will join the court in December, and Gleeson, the daughter of former chief justice Murray Gleeson, will take up her seat in March next year.

Both judges will be watched closely by those who understand that the High Court can fundamentally change the direction of our country, too. Eighty per cent of its cases are mundane, having little impact on the country. The other 20 cent are the Big Bang cases. Through the intersection of law, politics and values, they can cause seismic shifts throughout the country.

Will Steward and Gleeson become roaming judicial adventurers making decisions like philo­sopher kings rather than humble judges? There are no guarantees. After all, the court’s most recent appointment, and disappointment, is Justice James Edelman. Part of the recent 4-3 majority decision in Love v The Commonwealth, along with fellow justices Michelle Gordon, Geoffrey Nettle and Virginia Bell, Edelman dreamt up a legally bogus racial privilege to exclude two men from the normal application of our non-citizens laws.

Chief Justice Susan Kiefel’s scathing rebuke of the majority should be inscribed somewhere along the hallowed halls of the High Court for the newcomers.

“Implications are not devised by the judiciary,” Kiefel said, because they are “antithetical to the judicial function since they involve an appeal to the personal philosophy or preferences of judges”.

The departure of Nettle and Bell means that, without the support from the new appointees, Edelman and Gordon might be relegated to minority dissents the next time they choose to cook up propositions to suit their preferred outcomes, and pronounce them as the law of the land.

All eyes will be on the newest judges especially if the High Court decides to hear the case involving physics professor Peter Ridd. In August, Ridd lodged a 13-page ­application for special leave to ­appeal a 2018 Federal Court decision that upheld his sacking by James Cook University. On Thursday, the High Court agreed to hear oral arguments about special leave in February next year. This is interesting. The vast maj­ority of applications are rejected “on the papers” — in other words without an oral hearing.

Next, the High Court will decide if the Ridd case is sufficiently important to warrant judgment from the nation’s highest court. There is, as former High Court judge Michael Kirby once said, no point pretending that it is a logical or scientific process. In other words, it’s down to whether the court finds a matter interesting. The test is subjective, their decision unappealable.

For the punters, the raw odds are about one in 10: last year, of a total of 445 special leave applications, the court granted leave in 52 cases.

Insiders give Ridd a 50-50 chance of making it over the next hurdle. The case, after all, is not just about the “substantial injustice” of JCU’s termination of Ridd’s career, claiming he acted in an uncollegial manner in breach of the university’s vaguely drafted code of conduct when he raised questions about the quality of climate research at JCU.

If the High Court grants Ridd special leave to appeal, the court’s final determination is likely to ­reverberate across the country. Many universities have intellectual freedom clauses in their ­enterprise agreements with academics. And most universities have ambiguously drafted codes of conduct that could be used to restrict these same intellectual freedom clauses. Where does that leave academic freedom in this country?

Ridd’s case is being led by Melbourne QC Stuart Wood, while JCU has Bret Walker SC in its corner. Ridd’s claim for special leave to appeal includes a powerful observation from legal scholar Ron­ald Dworkin that “any invasion of academic freedom is not only harmful in itself, but also makes future invasions more likely”.

There is another harm to ­society. If JCU’s infringement of academic freedom is allowed to stand, it will have a chilling effect on other academics. We will never know what research escapes rigorous testing by academics who do not want to jeopardise their jobs.

The High Court is being asked to rule on the core mission of a university: is it, first and foremost, to defend academic freedom and further research, to seek the truth by challenging orthodoxies that can become dangerously inaccurate over time?

If, on the other hand, universities are allowed to sack academics in circumstances similar to Ridd, with obvious impacts for the quality of research and learning, then Australians are entitled to confirmation of this dystopian brave new world at Australian universities from our highest court.

And dystopian it certainly is. Along with making 17 findings against Ridd, two speech directions and five confidentiality directions (even prohibiting him at one stage from speaking with his wife about the matter), JCU also issued a “no satire” direction against Ridd demanding he not make fun of the disciplinary proceedings.

No satire? It’s hard not to make fun of a taxpayer-funded university that censures, then sacks, a respected professor of physics, and employee of 27 years, a man ranked in the top 5 per cent of researchers globally for raising questions about the quality of climate science research at the Great Barrier Reef.

Only this week, this report slipped under the ABC News’s ­Armageddon radar: “Researchers have found a new reef that is as tall as a skyscraper in the waters off Cape York in north Queensland.” As Ridd told Inquirer this week, “we are constantly learning new, and incredible things about the reef”.

The shoddy, disproportionate treatment of the physics professor by JCU has become the centrifugal force to better protect academic freedom at universities, not just via the courts, but by parliament too.

Ridd’s sacking led Education Minister Dan Tehan to initiate a review into free speech and academic freedom at Australian universities in 2019 by Robert French. Nothing had been done prior to Tehan taking the portfolio. This week, Tehan tabled the Higher Education Support Amendment (Freedom of Speech) Bill 2020, which gives effect to legislative changes suggested by the former chief justice. The bill requires that universities commit to “academic freedom” — as defined by French — in return for getting registration, and taxpayer funds.

These are indeed interesting times for academic freedom, with a review under way by Professor Sally Walker into the implementation by universities of the model code on academic freedom also recommended by French.

The model code is intended to operate as an umbrella-like standard to fall over all university policies, codes, pronouncements, etc. If a particular enterprise agreement has a broader definition of academic freedom, that is great for academics at that university. If an EA offers less protection than French’s model code, then that model code will lift the standard of academic freedom protections. That will be a terrific boost for academic freedom across the country because, as experts who have trawled through EAs of Australian universities told Inquirer this week, none of the EAs offer more protection than French’s model code.

When Walker’s review is completed late next month, we will discover which vice-chancellors have dragged the chain, more cowardly corporatist controllers than defenders of robust intellectual excellence.

Their incalcitrant approach to academic freedom should firm up the minister’s resolve to stop the rot. Tehan’s next move might be to legislate that every university implement the full French model code as a requirement of university registration. Even if not legislated, the minister has a backdoor way to secure the same outcome. Under section 136 of Tertiary Education Quality and Standards Agency Act, Tehan can direct the university regulator to use the model code when enforcing the educational standards to Australian universities. With oversight from Senate Estimates, this could well transform TESQA, known as a wet-lettuce regulator, into a genuine guardian of university excellence acting in the best interest of academics, students, taxpayers and the country.

In other words, with the model code in place, either by law or ministerial directive, what happened to Ridd can never happen again. That, of course, will not help the unassuming, but determined, professor. His final appeal for justice, and common sense, rests with the High Court next year, when at least one new judge, maybe two, will be on the bench. No wonder we will be watching closely.

Australia’s gas plan will push the Reef to extinction


<i>A brainless Greenpeace emission below. Give them their assumptions and they would be right.  But all their assumptions are at best dubious.  

For instance, bleaching is mostly caused by sea-level fluctuations: Low level episodes in particular. They make no effort to look at that, They just regurgitate conventional assumptions

And coral is very good at regrowing so bleaching from whatever cause is never permanent.  Even Ove Hoegh Guldberg noted that rapid regrowth</i>


After three mass bleaching events in the last five years, the Great Barrier Reef is not as great as it once was. Now, as Australia attempts to rebuild from the economic fallout of COVID-19, a new threat has emerged which could threaten the world’s largest living organism even further.

Scientists have made it clear that the blame for warmer and more acidic oceans lies on coal, the number one driver of climate change. But now that the Australian Federal government is pushing for a so-called “gas-led recovery” from the COVID-19 pandemic, the role of gas in the Reef’s demise can no longer go unscrutinised.

Rather than heeding the best advice of scientists and switching Australia from polluting coal and gas to clean energy sources like wind and solar, the Australian Federal Government is instead laying the groundwork to replace one destructive fossil fuel with another. If the government’s gas dreams become reality, the implications for the Reef could be cataclysmic.

In its 2019 Production Gap Report, the UN warned that in order to keep global heating at 1.5 degrees, gas production must decline by 20 percent by 2030.

“The continued rapid expansion of gas supplies and systems risks locking in a much higher gas trajectory than is consistent with a 1.5 degree Celsius or 2 degree Celsius future,” the report reads.

“These declines mean that most of the world’s proven fossil-fuel reserves must be left unburned.”

The Intergovernmental Panel on Climate Change (IPCC) special report on the impact of 1.5C of global warming found that coral reefs would likely decline between 70% and 90% if the temperature increased to that level. If global warming reaches 2C, more than 99% of coral reefs could be wiped out.

Climate change expert and researcher at the Australian National University, Professor Will Steffen, was unequivocal that gas has already damaged the Reef and expanding the industry would only make that damage worse.

“There is no doubt that climate change is the primary driver of the bleaching of the Great Barrier Reef,” Professor Steffen said.

“Climate change is caused by the burning of fossil fuels like gas, so there is a direct link between the greenhouse gas emissions from Australia’s gas industry, whether the gas is burned in Australia or elsewhere in the world, and the degradation and destruction of the Great Barrier Reef.”

Scientists all at sea with alarmist barrier reef warning



<i>Fancy theories preferred to the real world</i>

A new scientific paper, received with great fanfare among inter­national media and Australia’s public broadcaster, the ABC, claims half the corals of the Great Barrier Reef are dead.

The paper is by academics at James Cook University’s ARC Centre for Excellence for Coral Reef Studies. It is a scary headline. But is it true?

This finding is not based on any tried and proven method. Rather, the researchers from James Cook University have come up with a new method of statistical analysis based on a complicated “proxy” to estimate “colony size”.

The study itself was undertaken in 2016 and 2017, just after a coral bleaching event at cyclone-damaged reefs. If they had used traditional methods and longer time frames, it would likely be found that there is actually nothing wrong with the Great Barrier Reef.

Great Barrier Reef photographer Julia Summerling wrote recently about how a section known as North Direction Island, saying that the island’s corals were “savaged beyond recognition” due to Cyclone Ita in 2014, cyclone Nathan in 2015, and a coral bleaching event in the summer of 2016. So it was probably not the most representative time to be sampling. But the headlines are based on proxy measures from just a few reefs at that time.

She now says those areas have since recovered. “What I saw — and photographed — I could hardly believe. Young dinner-plate-sized corals were crammed into every available space on the limestone plateau as far as I could see, bristling with iconic fish life, from maori wrasse and coral trout to bumphead parrotfish and sweetlips. I swam a long way on the dive, checking to see how far the coral shelf stretched. The further I swam, the denser the coral fields became.”

For a new Institute of Public Affairs film, in January this year I visited the Ribbon reefs with Emmy award-winning photographer Clint Hempshall to follow the edge of Australia’s continental shelf to find and film coral bleaching. It was meant to be one of the worst-affected regions — 60 per cent dead from bleaching, which the same scientists say is caused by climate change. But we could not find any significant bleaching. We mostly found jewelled curtains of coral, appearing to cascade down underwater cliff faces. So colourful, so beautiful, all in crystal clear and warm waters.

The problem for Professor Terry Hughes, who co-authored the research, is that his study was undertaken in 2016 and 2017 then extrapolated out to cover other years. All of the research and subsequent media attention points to a narrative that the Great Barrier Reef is at risk of imminent collapse from climate change.

It was for questioning this claim, and the quality of science behind it, that Dr Peter Ridd was eventually sacked from James Cook University. Part of those claims by Ridd were that a lot of the science coming out of JCU’s ARC Centre for Excellent in Coral Reef Studies “is not properly checked, tested or replicated, and that 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 anymore.”

Neither James Cook University, nor Hughes, have ever rebutted Ridd’s criticisms of the research.

This is what objective observers need to put into context when examining Hughes’s most recent claims. Ridd also said: “I think that most of the scientists who are pushing out this stuff, I think that they genuinely believe that there are problems with the reef, I just don’t think they are very objective about the science they do. I think they’re emotionally attached to their subject and you can’t blame them the reef is a beautiful thing.”

One quick glance at Hughes’s Twitter account and you will find he is critical of the Morrison government’s gas-led recovery, cheerleading for a royal commission into the Murdoch media and constantly criticises the Adani Coal mine.

The new paper by James Cook University scientists claims both the incidence of coral bleaching and cyclones is increasing, but there is no evidence to support ­either contention. The available data from 1971 to 2017 indicated there has actually been a decrease in both the number and severity of cyclones in the Australian region.

Coral-bleaching events tend to be cyclical and coincide with periods of exceptionally low sea levels. As discussed in a new book, Climate Change: The Facts 2020, there were dramatic falls in sea levels across the western Pacific Ocean in 2016. These were associated with an El Nino event.

Until recently, coral calcification rates were calculated based on coring of the large Porites corals. There are well-established techniques for coring the Porites corals and then measuring growth rates. So why do Hughes and his colleagues stray from these tried and tested methods?

Since 2005, the Australian Institute of Marine Science has stopped using this technique to measure how well corals are growing at the Great Barrier Reef. The few studies still using the old technique suggest that, as would be expected, <font color="#ff0000"> as water temperatures have increased marginally, coral growth rates have also increased.</font>

But rather than admit this, key Great Barrier Reef research institutions have moved from such ­direct measures to new and complicated “proxies”. They thus have more flexibility in what they find because the measurement is no longer one that represents coral growth rates or coral cover.

As proxy votes are something delegated, this gives the researchers at JCU the potential to generate what might be considered policy-based evidence. And yet without question, the media reporting of the most recent research is that “there is no time to lose, we must sharply decrease greenhouse gas emissions”.

Far too frequently, climate science has demonstrated noble cause corruption — where the ends justify the means. We will only know exact coral calcification rates, and changing trends in coral cover, when our once esteemed research institutions return to more traditional methods of measuring such important indicators of coral health and growth.

We need a return to real science that is based on real observations and real measurements and then we may find written in journals what we see in the real world when we jump off boats and go under the sea.

The Great Barrier Reef has lost half its corals


The heading above -- from a Warmist outfit -- is most implausible. If it were true,it would have been widely noted by now but it appears to be the first such claim.  And the journal article they rely on contradicts it:  

"The relative abundances of large colonies remained relatively stable"

And the reference to"greenhouse gases" is also not in the original report.  

There has undoubtedly been some loss of coral cover in some places in recent years but the cause is conjectural.  Many things affect coral abundance, not the least of wich is heavy weather in the form of cyclones etc.  

One of the largest declines happened during a fall in the sea level in the general area.  And that exposed corals to unusual dessicatory and other damage

And, finally, even research by doomsayer Hoegh-Guldberg has revealed that bounce-back of damaged coral is very good.  So the mere fears in the article below are unpersuasive

Journal abstract included below



A new study of the Great Barrier Reef shows populations of its small, medium and large corals have all declined in the past three decades.

Lead author Dr Andy Dietzel, from the ARC Centre of Excellence for Coral Reef Studies (CoralCoE), says while there are numerous studies over centuries on the changes in the structure of populations of humans—or, in the natural world, trees—there still isn’t the equivalent information on the changes in coral populations.

“We measured changes in colony sizes because population studies are important for understanding demography and the corals’ capacity to breed,” Dr Dietzel said.

He and his co-authors assessed coral communities and their colony size along the length of the Great Barrier Reef between 1995 and 2017. Their results show a depletion of coral populations.

“We found the number of small, medium and large corals on the Great Barrier Reef has declined by more than 50 percent since the 1990s,” said co-author Professor Terry Hughes, also from CoralCoE.

“The decline occurred in both shallow and deeper water, and across virtually all species—but especially in branching and table-shaped corals. These were the worst affected by record-breaking temperatures that triggered mass bleaching in 2016 and 2017,” Prof Hughes said.

The branching and table-shaped corals provide the structures important for reef inhabitants such as fish. The loss of these corals means a loss of habitat, which in turn diminishes fish abundance and the productivity of coral reef fisheries.

Dr Dietzel says one of the major implications of coral size is its effect on survival and breeding.

“A vibrant coral population has millions of small, baby corals, as well as many large ones— the big mamas who produce most of the larvae,” he said.

“Our results show the ability of the Great Barrier Reef to recover—its resilience—is compromised compared to the past, because there are fewer babies, and fewer large breeding adults.”

The authors of the study say better data on the demographic trends of corals is urgently needed.

“If we want to understand how coral populations are changing and whether or not they can recover between disturbances, we need more detailed demographic data: on recruitment, on reproduction and on colony size structure,” Dr Dietzel said.

“We used to think the Great Barrier Reef is protected by its sheer size—but our results show that even the world’s largest and relatively well-protected reef system is increasingly compromised and in decline,” Prof Hughes said.

Climate change is driving an increase in the frequency of reef disturbances such as marine heatwaves. The study records steeper deteriorations of coral colonies in the Northern and Central Great Barrier Reef after the mass coral bleaching events in 2016 and 2017. And the southern part of the reef was also exposed to record-breaking temperatures in early 2020.

“There is no time to lose—we must sharply decrease greenhouse gas emissions ASAP,” the authors conclude.

Long-term shifts in the colony size structure of coral populations along the Great Barrier Reef

Andreas Dietzel et al.&

Abstract

The age or size structure of a population has a marked influence on its demography and reproductive capacity. While declines in coral cover are well documented, concomitant shifts in the size-frequency distribution of coral colonies are rarely measured at large spatial scales. Here, we document major shifts in the colony size structure of coral populations along the 2300 km length of the Great Barrier Reef relative to historical baselines (1995/1996). Coral colony abundances on reef crests and slopes have declined sharply across all colony size classes and in all coral taxa compared to historical baselines. Declines were particularly pronounced in the northern and central regions of the Great Barrier Reef, following mass coral bleaching in 2016 and 2017. The relative abundances of large colonies remained relatively stable, but this apparent stability masks steep declines in absolute abundance. The potential for recovery of older fecund corals is uncertain given the increasing frequency and intensity of disturbance events. The systematic decline in smaller colonies across regions, habitats and taxa, suggests that a decline in recruitment has further eroded the recovery potential and resilience of coral populations.

Reports of Reef’s demise greatly exaggerated

 

If we are to believe the Queensland Labor Government, sugarcane farmers are evil and are destroying the Reef in their pursuit of greater profits with their use of fertilisers.

To counter this, new regulations are going to be introduced.

These will have the handy effect of allowing the Government to trumpet its environmental credentials while at the same time pandering to the Greens, the latter being an article of faith held dear by Labor governments.

Given this, it was intriguing to hear the head of the Australian Institute of Marine Science, Paul Hardisty, concede under questioning before an ongoing Senate inquiry that only 3 per cent of the Reef, the inshore reef, was affected by farm pesticides and that even that 3 per cent was at “low to negligible risk”.

This in effect means that 97 per cent of the Great Barrier Reef, which lies 50km to 100km off the coast, is completely unaffected.

It is also worth noting that while scientists regularly shriek warnings that the Reef is dying and in so doing damage the tourism industry, no one has bothered to measure coral growth or the lack of it for the past 15 years.

Marine scientist Peter Ridd, who questioned the validity of claims made regarding the imminent death of the Reef by his peers, was sacked by James Cook University for his impertinence.

James Cook has since spent hundreds of thousands of dollars of university funds pursuing him through the courts.

AgForce reef taskforce chairman Alex Stubbs says cane farmers have been persecuted by the Queensland Department of Environment and Science over the issue of water quality and the health of the Reef.

The proposed legislation, he said, had been cooked up by bureaucrats, was fundamentally flawed and would do untold damage to the sugar cane industry. Guess which political party cane farmers will be putting at the bottom of their ballot papers at the October 31 state election.

If sugarcane farmers are the bad guys, then coal miners are the devil incarnate which is why the State Government keeps stalling approval of a planned expansion of the New Acland mine near Oakey.

There is also the small matter of pandering to – you guessed it – the Greens.

Coal is bad, we are told. Coal kills. It causes climate change, bushfires and if it continues to be mined, will lead to the extinction of civilisation.

The world, we are lectured, is abandoning coal and it’s pointless for Australia to keep mining it because nobody wants the stuff.

Companies that do business with coalminers are threatened with consumer boycotts, and cowardly executives acquiesce in the face of the baying of the mob and divorce themselves from coal.

Driven by fear, not reason, they abandon their responsibilities to their shareholders in their desperate efforts to appear to be ”woke.”

The Chinese, who don’t care in the least about being woke, must be more than a little bemused by all this as they continue to build and approve coal-fired power stations at a record rate.

Germany recently commissioned a new coal-fired power plant, Japan has plans to build more than 20, India is increasing its coal-fired electricity generation by more than 20 per cent, while Indonesia, Mozambique, Malawi, Bangladesh, Pakistan, South Africa, Zimbabwe, Philippines, Vietnam and Serbia are all building coal-fired power plants.

The Age of Reason may be dead, but on the evidence it appears that coal is not.

The Reef also stubbornly refuses to fulfil the prophesies of its imminent demise, even when it is forecast by such towering intellectuals as Leonardo Di Caprio, who has never seen the Reef but pronounced it to be near death in 2016, as did then US president Barack Obama when he treated Australians to his ignorance in 2014.

This brings us to politicians. Is it true or false that a person like, let’s say Victorian Premier Andrews, would lie after swearing on the Bible to tell nothing but the truth?

Have a guess.

Much of Queensland's legislation against farmers was 'completely unnecessary'


Marine scientist and physicist Professor Peter Ridd says data showing pesticides bear a a negligible impact on the Great Barrier Reef means much of the Queensland government’s new legislation against farmers were “completely unnecessary”.

Professor Ridd said it was recently revealed by the director of the Australian Institute of Marine Science, that only 3 per cent of the whole Great Barrier Reef, the ‘inshore reefs’, was affected by farm pesticides.

He said it was revealed even for the affected 3 per cent, pesticides were a low to negligible risk.

“It’s only 3 per cent of the whole Great Barrier Reef, and even when you look at the data on that ... even on that 3 per cent, pesticides are a low to negligible risk," Professor Ridd told Sky News host Chris Kenny.

“(Which) basically means a lot of this new legislation the Queensland government is bringing on against farmers is completely unnecessary.”

Scientific cancel culture exposed



An inquiry into Great Barrier Reef farming yields remarkable confessions as institutions are challenged by evidence.

By PETER RIDD

The Senate committee inquiry into the regulation of farm practices impacting water quality on the Great Barrier Reef has yielded some remarkable confessions by science institutions about the state of the reef. It has been the first time many of the scientists have been asked difficult questions and publicly challenged by hard evidence. They have been forced out of their bubble.

It was revealed by Paul Hardisty, boss of the Australian Institute of Marine Science, that only 3 per cent of the reef, the “inshore reefs”, is affected by farm pesticides and sediment. He also stated that pesticides, are a “low to negligible risk”, even for that 3 per cent.

The other 97 per cent, the true offshore Great Barrier Reef, mostly 50km to 100km from the coast, is effectively totally unharmed by pesticides and sediment.

This has been evident in the data for decades but it is nice to see an honest appraisal of the situation.

Why has this fact not been brought to the public’s attention in major documents such as the GBR Outlook Report produced by the Great Barrier Reef Marine Park Authority? Why has everybody been deceived about the true extent of the problem?

AIMS was also forthcoming on other important points. Records of coral growth rates show no impact from agriculture. Large corals live centuries, and have annual growth rings like trees. They record their own rate of growth. If farming, which started about 100 years ago on the reef coast, was damaging it, there should be a slowing of the growth rate. The records show no slowing when agriculture started a century ago, or when large-scale use of fertiliser and pesticides began in the 1950s.

I have written previously that AIMS has been negligent in not updating the GBR-average coral growth data for the past 15 years. We have the scandalous situation that there is data going back centuries – but nothing since 2005. AIMS claimed coral growth rates collapsed between 1990 and 2005, due to climate change; however, there is considerable doubt about this result because AIMS changed the methodology for the data between 1990 and 2005. At the Senate inquiry, under some duress, AIMS agreed it would be a good idea to update this data if the government will fund the project.

Updating the coral growth rate data will be a major step forward. It will prove or disprove the doubtful decline between 1990 and 2005. It will also give the complete record of how the GBR has fared in the past 15 years, a period when scientists have become more strident in their claims that it is on its last legs.

Hardisty, to his credit, has recently implemented red-blue teams within his organisation to help with quality assurance of the work that AIMS produces. A red team is a group of scientists that takes a deliberately antagonist approach to check, test and replicate scientific evidence. A genuine red team is a far more rigorous quality assurance approach than the present system used in science – peer review – which is often little more than a quick read of the work by the scientist’s mates. What AIMS has done internally is similar to what I have been proposing – an Office of Science Quality Assurance that would check, test, and replicate scientific evidence used for public policy.

Unfortunately, Hardisty’s commitment to quality in science was not reflected by many other important witnesses at the Senate inquiry. Many are in denial and resorted to shooting the messengers. An extract from a letter signed by Professor Ian Chubb, a former Australian chief scientist, was read out by Senator Kim Carr.

Disputing the conventional wisdom on the reef was likened to denying that tobacco causes cancer, or that lead in petrol is a health risk. Worse still, the reason sceptics do this, apparently, is “usually money”. Scientists such as Dr Piers Larcombe, the pre-eminent expert on the movement of sediment on the reef, with decades of experience, is thus written off as a corrupt charlatan.

It is scientific “cancel culture”. It is easier than confronting Larcombe’s evidence that farming has very limited impact on the GBR.

It is customary to be very cynical of our politicians, but it was senators Roberts, Rennick, Canavan and McDonald who forced some truth from our generally untrustworthy science institutions. Only our politicians can save us from them.

The evidence about the reef will not be buried forever. All the data indicates agriculture is having a negligible impact on the reef, and recent draconian Queensland legislation against farmers is unwarranted. And this issue will be influential come the Queensland state election on October 31.

Revealed: how the Great Barrier Reef is really doing


<i>Even the academics are finding it hard to moan about it</i>

Is it dying or thriving? The state of the Great Barrier Reef has become a hot button topic, but a report out today gives the most complete picture of the state of our most valuable national icon.

Reports of the death of the Great Barrier Reef may have been exaggerated, with new research showing “encouraging” signs of coral growth in two-thirds of 86 monitored reefs.

The annual report of the health of the reef by the Australian Institute of Marine Science, published today, has been welcomed by tourism operators who say they are battling widespread perceptions the reef is already dead.

Today’s report shows modest increases in coral coverage in the reef’s central and southern zones, and a stabilisation in the north, after several years of hits from bleaching, cyclones and outbreaks of the crown-of-thorns starfish.

Head researcher Dr Mike Emslie said the survey, which is now in its 35th year, showed “the reef is resilient, but this resilience has limits”.

Dr Emslie’s team conducted their assessment between September 2019 and June 2020 at reefs scattered from below Rockhampton to the very tip of Cape York. The work is done by means of a “manta tow”, in which a marine scientist is pulled along a section of the reef underwater for two minutes, and afterwards calculates the percentage of sea floor covered by coral.

“Out of the 86 reefs we surveyed this year, two thirds were low or moderate, with less than 30 per cent coral cover,” he said. “There were 23 reefs that had high coral cover, which is 30 to 50 per cent, and only five had very high coral cover, over 50 per cent.”

Comparing this year’s results to previous years of coral coverage gives a different perspective on the health of the reef.

In the northern reef, coral coverage in 2020 was just half of what it was at its recorded peak, and in the southern reef it was at 60 per cent of its best-ever result. The peaks in both areas were recorded in 1988.

Coral coverage in the central part of the reef reached its highest level ever recorded in 2016, Dr Emslie said, but this year the coverage had fallen back to 61 per cent of that peak.

“The reef is taking repeated hits from coral bleaching, cyclones and crown-of-thorns outbreaks. While we have seen the Great Barrier Reef’s ability to begin recovery from these pressures, the frequency and intensity of disturbances means less time for full recovery to take place,” Dr Emslie said.

The full effect of last summer’s mass bleaching event – the third in five years – would not be known for several months, he added.

“The 35-year data set we’ve got shows that the long term trajectory of hard coral cover is actually ratcheting down,” Dr Emslie said.

“There are lot of good reefs still out there, but there’s also lots of impacted reefs. People can still go out and see the Great Barrier Reef in all its glory but we really need to be aware of what the long term data is telling is.”

Gareth Phillips, CEO of the Association of Marine Park Tour Operators and himself a reef scientist, said people who worked on the reef were seeing its recovery day to day, but negative publicity about the condition of the reef had been affecting visitor numbers prior to the coronavirus outbreak.

“The overwhelming message is ‘Go now to see what’s left, and what you will probably see is this stark white reef that’s just on it’s last legs’. It’s just completely false,” he said.

“Marine operators do not deny that the reef has gone through some substantial pressures but as this report has shown, the reef has ability to recover,” Mr Phillips said. “It’s exactly in line with what the operators have been trying to say – that the reef is not dead and it is a beautiful place.”

Tourism operations on the reef were currently running at about 10-15 per cent of their pre-COVID capacity, Mr Phillips said, but he rejected popular suggestions this lack of activity could help the reef “heal”.

“Tourism actually has a positive impact on the reef,” he said. “With recent bleaching events, the tourism locations had very little impact because (operators) showed good stewardship. They monitor the reef. They’re a critical part of its management.”

The lack of commercial enterprise on the reef during the lockdown was also leading to an increase in illegal fishing in the area because the tourism boats provide surveillance, Mr Phillips said.

Cairns Tourism Industry Assocition president Kevin Byrne said operators were “continuously fighting against this over-egging of the decline of the Great Barrier Reef”.

The perception that the reef was dying was “fuelled by the contest of academics to try and paint the most gloomy picture,” he said. “The reef needs to be managed, it doesn’t at the moment need to be saved.”

According to the Great Barrier Reef Marine Park Authority, there were 2.1 million “visitor days” to the reef in 2019.

Ridd Case: IPA Welcomes Historic High Court Appeal


<i>Ridd was fired for challenging Greenie lies about the Great Barrier Reef</i>

The Institute of Public Affairs has welcomed the announcement that Dr Peter Ridd will appeal the judgement in the case of James Cook University (JCU) v Peter Ridd to the High Court of Australia. Dr Ridd is seeking to reverse the 2-1 decision of the Federal Court of Australia, which overturned the earlier decision in the Federal Circuit Court, which held that Dr Peter Ridd was unlawfully dismissed by JCU.

“This is an historic appeal. It will be the first time that the High Court has been asked to adjudicate on the meaning of intellectual freedom,” said Gideon Rozner, IPA Director of Policy.

“The fundamental issues of free speech at Australian universities, the future of academic debate and freedom of speech on climate change are all on the line in this historic High Court appeal.”

“This has been Australia’s David vs Goliath battle. Dr Peter Ridd on one side backed by the voluntary donations of thousands of ordinary Australians, and JCU on the other side who with taxpayer funds secured some of the most expensive legal representation in the country in Bret Walker SC to stifle the free speech of one of its own staff.”

Dr Peter Ridd, a professor of physics at JCU, was sacked by the university for misconduct for questioning in the IPA’s publication Climate Change: The Facts 2017 the quality climate change science surrounding the Great Barrier Reef, and for public statements made on the Jones & Co Sky News program.

Dr Peter Ridd today reopened his Go Fund Me page, appealing to thousands of mainstream Australians to once again support his historic fight for free speech on climate change.

“Peter Ridd’s fight is representative of every Australian who has been censored, cancelled or silenced,” said Mr Rozner. “Alarmingly, the decision of the Federal Court shows that contractual provisions guaranteeing intellectual freedom do not protect academics against censorship by university administrators. This is a point where the IPA and the NTEU are on a unity ticket.”

“James Cook University’s actions prove there is a crisis of free speech at Australian universities. Many academics are censured, but few are prepared to speak out and risk their career, particularly if faced with the prospect of legal battles and possible bankruptcy.

“The case has identified a culture of censorship when it comes to challenging claims surrounding climate change and the Great Barrier Reef. JCU to this date has never attempted to disprove claims made by Dr Ridd about the Great Barrier Reef,” said Mr Rozner.

Academic freedom bows at the altar of social media



<i>The university was too canny to challenge Peter Ridd on his climate skepticism.  Instead they got him on a perverted legal technicality</i>

It’s out with philosophers John Stuart Mill, John Locke and Isaiah Berlin and it’s in with “the internet, social media and trolling”. According to the majority judgment of the Federal Court of Australia in James Cook University v Ridd handed down on Wednesday, that is.

Peter Ridd was employed by James Cook University for 27 years before his employment was terminated in May 2018 for serious misconduct. At the time Ridd was a physics professor. However, he was not dismissed on any academic or teaching grounds.

Rather, Ridd went down because JCU maintained that he had failed to act “in the collegial and academic spirit” required and had denigrated a fellow staff member by failing to act “with respect and courtesy”. Oh yes, Ridd had also denigrated JCU, the Australian Research Council Centre of Excellence for Coral Reef Studies and the Great Barrier Reef Marine Park Authority.

In fact, Ridd disagreed on scientific grounds with the views of some fellow academics and some influential organisations about the long-term viability of the Great Barrier Reef.

He maintains that sections of the Great Barrier Reef are in good shape and that coral dies and is reborn as part of the reef’s life. This is inconsistent with the scientific orthodoxy preached by JCU and like-minded organisations.

Announcing the termination in May 2018, Iain Gordon, then JCU’s deputy vice-chancellor, referred not to the quality of Ridd’s teaching and research but to his “manner” and “disrespect”. You see, he had been charged with having “trivialised, satirised or parodied” JCU’s disciplinary processes. Why, Ridd had even sent a private email to a friend dealing with JCU that was headed “for your amusement”. How shocking is that?

It is a long time since there was genuine academic and intellectual freedom in the groves of academe — if this ever existed. The ideals pronounced by John Henry Newman’s 1875 The Idea of a University are essentially utopian. What’s new about the current JCU case is that the curtailment of academic freedom that once prevailed in the social sciences has extended into the physical sciences.

Take Australia, for example. The two big cases of academic freedom in the past half-century involve philosopher Frank Knopfelmacher (1923-95) and physicist Ridd. In 1965 Knopfelmacher, who was a lecturer at the University of Melbourne, was appointed to the position of senior lecturer in philosophy at the University of Sydney. The appointment was overturned by the university’s professional board.

Knopfelmacher’s appointment was strongly supported by David Armstrong, one of Australia’s finest philosophers.

Like Ridd, Knopfelmacher went down because of his irreverent manner and a tendency to criticise colleagues in addition to his unfashionable views. An articulate and well-informed anti-communist, Knopfelmacher upset the leftist fashions of the time with his vehement criticism of the communist regimes in central and eastern Europe (East Germany, the Soviet Union) and Asia (North Korea, China, North Vietnam), and their supporters in the West.

In 1964 Knopfelmacher wrote an article in Twentieth Century magazine criticising the leftist ideology that prevailed in many of Melbourne University’s social science departments. He claimed that left-wing academics discriminated against non-leftists and exercised significant veto powers “in matters of academic preferments and sinecures”.

This accurate comment was used against Knopfelmacher by his opponents on Sydney University’s professional board.

In the half-century since the Knopfelmacher affair, the attack on academic and intellectual freedom has moved into universities as a whole, including the physical sciences. That is Ridd’s problem. JCU appears to have a view that the Great Barrier Reef is dying fast and anyone who disagrees with this orthodoxy, no matter how well qualified, does not have a right to be heard, especially if they are irreverent and outspoken.

In one sense, the Federal Court’s decision in JCU v Ridd turns on the interpretation of the enterprise agreement under which the respondent was employed.

In September last year the Federal Circuit Court (Judge Angelo Vasta presiding) found that JCU had contravened section 50 of the Fair Work Act by making findings against Ridd, giving him directions with respect to confidentiality and speech along with a “no satire” instruction. All this, the court found, had led to an improper employment termination.

However, the current case is more important than mere industrial relations. The majority — justices John Griffiths and Sarah Derrington — essentially dismissed “historical concepts of academic freedom”.

So the thoughts of Mill, Locke and Berlin are out of date. Griffiths and Derrington instead cited the work of American philosopher Jennifer Lackey concerning the internet and social media. They quoted favourably from the Illinois academic, who has written that the concept of academic freedom has been challenged not only by no-platforming but also by student demands for “content warnings and safe spaces” that “leave us in uncharted territory”.

Newman, originally an Anglican who became a cardinal in the Catholic Church, was a deeply religious man who saw a role for an essentially secular university bestowed with intellectual freedom. But many a modern campus has become an institution that acts in accordance with the notion that “error has no rights”.

This was once the teaching of extreme religious sects. Now it is being put into effect by censorious administrators, academics and students who believe that those with whom they disagree have no right to be heard.

In his dissent, Justice Darryl Rangiah placed much more emphasis on Ridd’s right to intellectual freedom. Rangiah agreed with the majority that the decision of the primary judge contained material errors on industrial law.

However, he said that while the appeal should be allowed, the proceedings should not be dismissed but remitted for a further hearing. Rangiah did not support the majority view that some aspects of Ridd’s conduct cannot be characterised as an exercise in intellectual freedom.

While JCU v Ridd turns primarily on industrial law, it is likely to have the unintended consequence of discouraging academics who are at odds with prevailing fashions in the social and physical sciences from speaking out.

Australian universities need more Knopfelmachers and Ridds — not fewer.

Dr. Ridd: James Cook University wins unlawful sacking decision


The grounds for the university's actions were contemptible.  He was sacked for disagreeing with his colleagues.  If academics cannot disagree with one-another, where does that leave the search for truth?

He was not even abusive in what he said. He just said that their conclusions needed more validation -- a scientific comment if ever there was one.  

This needs to go to appeal but funding may be a barrier to that

The reason for the furore is that the JCU scientists said that the reef was damaged by global warming.  Dr. Ridd demurred



The Federal Court has allowed an appeal of a decision which found James Cook University acted unlawfully in its 2018 sacking of Peter Ridd, after the professor questioned colleagues' research on the impact of global warming on the Great Barrier Reef.

Dr Ridd was awarded $1.2 million in damages by the Federal Circuit Court in September, which had earlier found JCU sacked the physics professor unlawfully.

The case attracted intense focus due to Dr Ridd's scepticism of climate change science and the broader debate about free speech at Australian universities.

The university reiterated last year it would launch the appeal, and has maintained its sacking of the professor was based on his treatment of colleagues rather than the expression of his scientific views.

Dr Ridd had originally sought reinstatement to his position but later abandoned this in favour of compensation.

In a judgment published on Wednesday, the Federal Court set aside that compensation decision and allowed the university to appeal the earlier ruling it had acted unlawfully.

Justices John Griffiths and Roger Derrington found Dr Ridd's enterprise agreement did not give him "untrammelled right" to express his professional opinions beyond the standards imposed by the university's code of conduct.

The termination of his employment did therefore not breach the Fair Work Act, they said.

Outlining his final declarations and penalties last year in September, Federal Circuit Court Judge Salvatore Vasta suggested the university's conduct had bordered on "paranoia and hysteria fuelled by systemic vindictiveness".

"In this case, Professor Ridd has endured over three years of unfair treatment by JCU – an academic institution that failed to respect the rights to intellectual freedom that Professor Ridd had as per [his enterprise agreement]," the judge decided.

Conservative think-tank the Institute of Public Affairs described the new Federal Court judgment on Wednesday as a "devastating blow" to freedom of speech.

"Alarmingly, this decision shows that contractual provisions guaranteeing intellectual freedom do not protect academics against censorship by university administrators," IPA director of policy Gideon Rozner said. "The time has come for the Morrison government to intervene."

He added that Dr Ridd was now considering his legal options around a High Court challenge.

Study: As Sea Levels Rise, Island ‘Drowning’ Is Not Inevitable



Coral reef islands across the world could naturally adapt to survive the impact of rising sea levels, according to new research.

The increased flooding caused by the changing global climate has been predicted to render such communities – where sandy or gravel islands sit on top of coral reef platforms – uninhabitable within decades.

However, an international study led by the University of Plymouth (UK) suggests that perceived fate is far from a foregone conclusion.

The research, published in Science Advances, for the first time uses numerical modeling of island morphology alongside physical model experiments to simulate how reef islands – which provide the only habitable land in atoll nations – can respond when sea levels rise.

The results show that islands composed of gravel material can evolve in the face of overtopping waves, with sediment from the beach face being transferred to the island’s surface.

This means the island’s crest is being raised as sea level rises, with scientists saying such natural adaptation may provide an alternative future that can potentially support near-term habitability, albeit with additional management challenges, possibly involving sediment nourishment, mobile infrastructure, and flood-proof housing.

The research was led by Gerd Masselink, Professor of Coastal Geomorphology in Plymouth, working with colleagues at the University of Auckland (New Zealand) and Simon Fraser University (Canada).

Professor Masselink, who heads Plymouth’s Coastal Processes Research Group, said:

“In the face of climate change and sea-level rise, coral reef islands are among the most vulnerable coastal environments on the planet. Previous research into the future habitability of these islands typically considers them inert structures unable to adjust to rising sea level. Invariably, these studies predict significantly increased risk of coastal flooding and island inundation, and the concept of ‘island loss’ has become entrenched in discourses regarding the future of coral reef island communities. In turn, this has led to attention being focused on either building structural coastal defenses or the exodus of island communities, with limited consideration of alternative adaptation strategies.

“It is important to realize that these coral reef islands have developed over hundreds to thousands of years as a result of energetic wave conditions removing material from the reef structure and depositing the material towards the back of reef platforms, thereby creating islands. The height of their surface is actually determined by the most energetic wave conditions, therefore overtopping, flooding, and island inundation are necessary, albeit inconvenient and sometimes hazardous, processes required for island maintenance.”

Co-author Professor Paul Kench, currently Dean of Science at Simon Fraser University, Canada, said:

“The model provides a step-change in our ability to simulate future island responses to sea-level rise and better resolve what the on-ground transformations will look like for island communities. Importantly, our results suggest that island drowning within the next few decades is not universally inevitable. Understanding how islands will physically change due to sea-level rise provides alternative options for island communities to deal with the consequences of climate change. It is important to stress there is no one-size-fits-all strategy that will be viable for all island communities – but neither are all islands doomed.”

For the research, scientists created a scale model of Fatato Island, part of the Funafuti Atoll in Tuvalu, and placed it in the Coastal Ocean and Sediment Transport (COAST) Lab at the University of Plymouth.

It was then subjected to a series of experiments designed to simulate predicted sea level rises with the results showing that the island’s crest rose with the rising sea level while retreating inland, as a result of water overwashing the island and depositing sediment on the island’s surface.

Peter Ridd’s Fight For Academic Freedom In Climate Science

 
This week the Federal Court appeal hearing took place for the case of Peter Ridd, Australian scientist, who was fired by his university after he had criticized Great Barrier Reef science.

Australian scientist and journalist Jennifer Marohasy is following the case closely and reports about the latest chapter in this sad saga:

To be truly curious we must confess our ignorance. The person who knows everything would have no reason to question, no need to experiment.

If they went in search of evidence, it could only be to confirm what they already knew to be true. Knowledge then would be something that conferred prestige, rather than something to be built upon.

It was because of Peter Ridd that I had to know if all the coral reefs off Bowen were dead, or not. I went looking for mudflats with a Gloucester Island backdrop after the first judgment was handed down, which was back last April 2019.

Of course, Peter was cleared by Judge Vasta in the Federal Court of all the misconduct charges that had resulted in his sacking. Yet the University appealed, and that appeal was heard this last week.

The university appealed because the modern Australian university can’t let a comprehensive win by a dissident professor go unchallenged.

The modern university is all about prestige, and they probably thought that eventually, Peter would run out of money, the money needed to defend himself in the courts. But they don’t know Peter, or the team backing him.

Yesterday Peter thanked both the Union and also the Institute of Public Affairs (IPA) for their support.

Peter also wrote:

    The Federal Court appeal hearing is over, and the lawyers have done their work. We now wait, possibly for some months, for the three judges to make the decision. In essence the appeal was about defining the limits of academic freedom, and what a university scientist can say, and how he or she might be allowed to say it.

    For example, was I allowed to say that due to systemic lack of quality assurance, scientific results from Great Barrier Reef science institutions was untrustworthy?

    JCU said I was not, [not] even if I believed it to be true.
    I am certainly not ashamed of anything I said, how I said it, or of my motivation.

    Irrespective of the outcome of the appeal, I can now focus on other matters.

    First, I will work tirelessly to raise the problem of hopeless quality assurance of the science of the GBR, including the effect of climate change on the reef. I am hoping that the Senate Inquiry will come out of Covid hibernation soon. I will also be pushing AIMS to release their missing 15 years of coral growth data, and JCU to release its buried report on possible fraud at its coral reef centre. It is shameful the contempt with which these institutions treat the people of the region.

    Second, I will work with those agricultural organisations that show a determination to fight, which is sadly far from all of them, to demonstrate that the recent unfair regulations on Queensland farmers are based on shoddy science.

    Third: I will work to encourage governments at both state and federal level to force universities to behave like genuine universities and not the glossy public relations companies that they have become. Governments must mandate the introduction of genuine and enforceable guidelines on academic freedom such as those outlined in the Commonwealth governments (unimplemented) review by ex-High Court judge, Robert French.

My IPA colleague Gideon Rozner has an important article in The Australian newspaper that provides much more context. The piece includes comment that:

    The Ridd case has resonated around Australia — and has attracted significant attention worldwide — for good reason. It confirms what many people have suspected for a long time: Australia’s universities are no longer institutions encouraging the rigorous exercise of intellectual freedom and the scientific method in pursuit of truth. Instead, they are now corporatist bureaucracies that rigidly enforce an unquestioning orthodoxy and are capable of hounding out anyone who strays outside their rigid groupthink.

    JCU is attempting to severely limit the intellectual freedom of a professor working at the university to question the quality of scientific research conducted by other academics at the institution. In other words, JCU is trying to curtail a critical function that goes to the core mission of universities: to engage in free intellectual inquiry via free and open, if often robust, debate. It is an absurd but inevitable consequence of universities seeking taxpayer-funded research grants, not truth.

    Worse still, it is taxpayers who are funding JCU’s court case. Following a Freedom of Information request by the Institute of Public Affairs, the university was forced to reveal that up until July last year, it had already spent $630,000 in legal fees. It would be safe to assume that university’s legal costs would have at least doubled since that time. The barrister who JCU employed in the Federal Court this week was Bret Walker SC, one of Australia’s most eminent lawyers. Barristers of his standing can command fees of $20,000 to $30,000 a day. And all of this is happening at the same time as the vice-chancellor of the university, Sandra Harding — who earns at least $975,000 a year — complains about the impact of government funding cuts.

    While Australian taxpayers are funding the university’s efforts to shut down freedom of speech, Ridd’s legal costs are paid for by him, his wife and voluntary donations from the public. As yet, neither the federal nor the Queensland Education Minister has publicly commented on whether JCU is appropriately spending taxpayers’ money and, so far, both have refused to intervene in the case.

Gideon Rozner is tireless and has also put together a fascinating 3-part podcast providing background into Peter Ridd’s fight for academic freedom. He interviewed me for this series.

The saga will continue for the next few years, whatever the judges decide. As will my interest in all things to do with the Great Barrier Reef.

Push to bring back Australia's lost oyster reefs


<i>This is one environmental progran that makes sense -- if the costs can be curtailed</i>

Australia's southern states had their own version of a Great Barrier Reef until it was erased almost entirely by the middle of last century.

Before European settlement, the flat oyster reef ecosystem that dominated southern waters lay like a wreath around the coastline in bays, inlets and harbours. But with the oyster beds harvested for food or broken up to be used in cement, these reefs were made functionally extinct.

Now scientists, recreational fishers, conservationists and local governments are calling for government funding to bring the reefs back. They say previous public investment in reef restoration has exceeded expectations and expanding it will be a cheap, quick and effective regional jobs stimulus.

What's more, bringing back an ecosystem from extinction to the point where it could regrow itself would be a world-first, James Cook University marine biologist Ian McLeod said.

"The reefs act as a catalyst for a new food chain … [they] support lots of fish and all sorts of marine life, seagrass, worms and crabs," Dr McLeod said.

"It's surprising how well things have been going" with the handful of installations already established, he said. Reefs have been rebuilt over recent years in places such as Victoria's Port Phillip Bay, South Australia's Gulf St Vincent, Western Australia's Oyster Harbour and Port Stephens in NSW.

Oysters, and the mussels that proliferate among them, cannot naturally recolonise without help. Since their natural habitat was removed, bays have silted over and they need a bedrock to cling on. However, it's an easy fix.

The only requirement is some quarried limestone, concrete or compressed old shells harvested from restaurants to serve as a bedrock, seeded with oyster sprat and dropped overboard.

The Nature Conservancy is leading the campaign for funding. With $100 million, 60 reefs – about a third of the natural range of shellfish reefs – could be brought back, generating 850 jobs in construction, fisheries and service industries, it said.

"The reefs come back like a miracle ecosystem and provide a huge environmental benefit," said Nature Conservancy Australia director Rich Gilmore.

"There's huge water quality benefits. Each oyster filters about 150 litres of water a day. And then there's the fish benefits too. One hectare of oyster reef can create 375 kilograms of fish a year."

Mr Gilmore said the pilot reef installations had met with "no community opposition, but have overwhelming community support".

Recreational Fishing Alliance of NSW president Stan Konstantaras said restoring oyster reefs was a "no-brainer".

"More habitat equals more fish," Mr Konstantaras said. "Places like Botany Bay have suffered huge amounts of habitat degradation … everywhere has been modified by development. Every estuary on the coast would benefit from having an oyster reef."

Dr McLeod said the world was at "peak oyster industry" when Australia was settled, with vast oyster industries in New York and London quickly harvesting all their native shellfish beds for food.

The same thing happened to Australia's flat oyster, which once flourished from Sydney to Tasmania and Perth, and the Sydney Rock oyster, which lives from around Noosa to Sydney. Limestone oyster reefs in bays and estuaries were also busted up and hauled ashore once Australia had exhausted its land-based limestone resources to make mortar and cement.

By the time the Second World War rolled around, the flat oyster reefs were gone.

Science and free speech under challenge from Greenie correctness


A court case this week in front of three judges of the Federal Court was a further stage in Peter Ridd’s fight for freedom of speech on climate change. The case, James Cook University v Peter Vincent Ridd, has enormous significance for the future of Australia’s universities and scientific institutions.

Ridd’s case is a dramatic illustration of the free speech crisis in Australian universities, not least around matters as politically and emotionally charged as climate change. It will determine, in effect, whether universities have the ability to censor opinions that threaten their sources of funding. It is one of the most important cases for intellectual freedom in the history of Australian jurisprudence.

The Ridd case has resonated around Australia — and has attracted significant attention worldwide — for good reason. It confirms what many people have suspected for a long time: Australia’s universities are no longer institutions encouraging the rigorous exercise of intellectual freedom and the scientific method in pursuit of truth. Instead, they are now corporatist bureaucracies that rigidly enforce an unquestioning orthodoxy, and are capable of hounding out anyone who strays outside their rigid groupthink.

JCU is attempting to severely limit the intellectual freedom of a professor working at the university to question the quality of scientific research conducted by other academics at the institution. In other words, JCU is trying to curtail a critical function that goes to the core mission of universities: to engage in free intellectual inquiry via free and open, if often robust, debate. It is an absurd but inevitable consequence of universities seeking taxpayer-funded research grants, not truth.

Worse still, it is taxpayers who are funding JCU’s court case. Following a Freedom of Information request by the Institute of Public Affairs, the university was forced to reveal that up until July last year, it had already spent $630,000 in legal fees. It would be safe to assume that university’s legal costs would have at least doubled since that time. The barrister who JCU employed in the Federal Court this week was Bret Walker SC, one of Australia’s most eminent lawyers. Barristers of his standing can command fees of $20,000 to $30,000 a day. And all of this is happening at the same time as the vice-chancellor of the university, Sandra Harding — who earns at least $975,000 a year — complains about the impact of government funding cuts.

While Australian taxpayers are funding the university’s efforts to shut down freedom of speech, Ridd’s legal costs are paid for by him, his wife and voluntary donations from the public. As yet, neither the federal nor the Queensland Education Minister has publicly commented on whether JCU is appropriately spending taxpayers’ money and, so far, both have refused to intervene in the case.

Ridd describes himself as a “luke-warmist”. “I think carbon dioxide will have a small effect on the Earth’s temperature,” he told an IPA podcast recently. “But it won’t be dangerous.” He has been studying the Great Barrier Reef since the early 1980s and was even, at one point, president of his local chapter of the Wildlife Preservation Society.

But Ridd is sceptical about the conventional wisdom that the Great Barrier Reef is dying because of climate change. “I don’t think the reef is in any particular trouble at all,” he says. “In fact, I think it’s probably one of the best protected ecosystems in the world and virtually pristine.”

The problems Ridd’s views cause for JCU are obvious. The university claims to be a leading institution when it comes to reef science, and has several joint ventures with taxpayer-funded bodies such as the Australian Research Council Centre for Excellence in Coral Reef Studies.

Ridd challenged his sacking in the Federal Circuit Court on the basis that the university’s enterprise agreement (which determined his employment conditions) specifically guaranteed his right to “pursue critical and open inquiry”, “express unpopular or controversial views”, and even “express opinions about the operations of JCU and higher education policy more generally”. In September last year, Ridd won his case as the court found he had been unlawfully sacked and he was awarded $1.2m in damages and compensation for lost earnings.

The case in the Federal Court this week was an appeal by JCU against that decision. At issue was whether the intellectual freedom clauses in the enterprise agreement covering JCU staff protected his criticism of quality assurance issues in reef science at the university. The university alleges that in going public with his concerns that organisations such as the ARC Centre “cannot be trusted” on reef science, Ridd committed several breaches of the university’s staff code of conduct, with its vague, faintly Orwellian requirements to act “collegiately”, and to “uphold the integrity and good reputation of the university”.

In other words, even though the enterprise agreement specifically declared that staff had the right to intellectual freedom, it was for the university to determine the limits of what that freedom actually permitted. If it is accepted, it will be the death knell of free intellectual inquiry in Australia’s universities. As Ridd’s barrister, Stuart Wood QC, said to the Federal Court: “If you can’t say that certain science cannot be trusted because it is ‘discourteous’ and ‘not collegial’, then you cannot call out scientific misconduct and fraud. It’s not just the end of academic freedom, it’s the end of the scientific method. At that point, JCU ceases to be a university and becomes a public relations outfit.”

An academic who doesn’t have the ability to challenge the research findings of their colleagues because those questions threaten the university’s funding doesn’t have intellectual freedom. And if academics know they could get sacked, as Ridd was, for asking uncomfortable questions, they will stop asking uncomfortable questions.

Academics should of course be open to criticism — particularly for some of their more outlandish conclusions — but as a matter of public policy it is vital that universities be places where bad ideas can be expressed as well as good ones. The difference between the former and the latter should be resolved by free and open debate, not opaque “disciplinary processes”. We may not like what university professors say, but a strong university sector requires that we defend to the death their right to say it.

It is up to the Federal Court now to decide exactly how far universities can go to censor and sack their staff. But in Ridd, James Cook University has one professor who will not go quietly.

A Queensland university that unlawfully sacked a professor for criticising colleagues for their research on the impact of global warming on the Great Barrier Reef is back in court


James Cook University is appealing the Brisbane Federal Circuit Court's finding that it contravened the Fair Work Act when it dismissed Peter Vincent Ridd in 2018.

Judge Salvatore Vasta made 28 findings in April 2019 against the university, which censured Prof Ridd for remarks against a coral researcher, the Australian Institute of Marine Science and the ARC Centre of Excellence for Coral Reef Studies.

The university was later ordered to pay Prof Ridd more than $1.2m for lost income, lost future income and other costs.

Before sacking the geophysicist, the university alleged Prof Ridd had violated its code of conduct during an August 2017 interview on Sky News when he remarked some of the university's research could "no longer be trusted".

It also alleged Prof Ridd wrote of a researcher in an email to a student: "It is not like he has any clue about the weather. He will give the normal doom science about the (Great Barrier Reef)".

Judge Vasta found the university's actions, including the dismissal, were unlawful.

"Incredibly, the university has not understood the whole concept of intellectual freedom," he wrote in his findings.

"In reality, intellectual freedom is the cornerstone of this core mission of all institutions of higher learning."

Freedom of expression and the interpretation of the university's code of conduct were the focus of the appeal submissions on Tuesday.

The university's lawyer, Bret Walker SC, said the university was responsible for enforcing standards of behaviour to protect intellectual freedom and the code of conduct.

Mr Walker said staff had the right to intellectual freedom and the right to express certain views but not bully, harass or intimidate others.

"Freedom .... is not without limit, restriction or standard," he told the court.

The two-day hearing continues.

Great Barrier Reef: Same old same old scares


Every couple of years we get the whines we read below:  The reef is being destroyed by global warming and farming.  But the reef is still there.  The prophecies of doom don't eventuate.

One should in fact gravely doubt the findings below.  Peter Ridd has shown that the JCU people routinely exaggerate reef damage.  There are always bare spots on the reef and these are attributed to global warming.  

But that is not so. It is the Crown of Thorns starfish that is responsible for most reef damage.  But from an aircraft you can't see starfish so the damage is all put down to global warming.  What you read below is therefore a travesty of science.  No effort was made to exclude competing explanations -- which is utterly basic in science.  They are propagandists, not scientists.



In another sad blow for the Australian environment, it has now been confirmed that once again climate change has taken its toll on one of its greatest natural wonders - the Great Barrier Reef.

The Great Barrier Reef is the world’s largest coral reef system, home to some 600 species of coral.

But a recent aerial study has confirmed scientists' worst fears, concluding that the reef is experiencing its third large-scale bleaching event in five years.

Coral bleaching is the direct result of warming sea temperatures, which causes corals to become stressed. In this situation, coral expels the symbiotic algae which lives within its tissues, which is responsible for its bright colour.

Usually bright and colourful jewels among the reef, bleaching leaves a stripped-bare skeleton of the coral behind.

Professor Terry Hughes, Director of the ARC Centre of Excellence for Coral Reef Studies at James Cook University, led a team of researchers to assess the extent of coral bleaching across the reef.

Professor Hughes said: “We surveyed 1,036 reefs from the air during the last two weeks in March, to measure the extent and severity of coral bleaching throughout the Barrier Reef region.

“For the first time, severe bleaching has struck all three regions of the Great Barrier Reef – the northern, central and now large parts of the southern sectors."

Aerial surveys concluded that while some areas of the reef have remained unscathed, large swathes in other regions have been severely bleached, casting ominous doubt over the reef's future.

The Great Barrier Reef Foundation has described the phenomenon as a “matter of huge concern”.

So in order to preserve and protect the Great Barrier Reef for years to come, what is the solution?

How can the Great Barrier Reef recover?

Dr Mark Eakin, Coordinator of NOAA's Coral Reef Watch program, said while people “continue to spew carbon dioxide” the current phenomenon will become a much more common occurrence.

He said: “This is the third widespread, severe coral bleaching in less than five years.

“As long as we continue to spew carbon dioxide and other heat-trapping gases into the atmosphere, corals will continue to bleach and die.

“Local efforts to reduce pollution on the reef and to restore reefs piecemeal help keep corals alive.

“If we want to save the Great Barrier Reef and other reefs around the world, we have to move off fossil fuels as quickly as possible.”

According to Dr Richard K.F. Unsworth, Senior Lecturer in Marine Biology at Swansea University, farming practices needs a significant overhaul in order for the reef to survive.

He said: “Although climate change is the primary cause of bleaching, the capacity of the reef to recover after bleaching events is improved when the water quality is high.

“This means low levels of nutrients, sediments and contaminants such as herbicides.

“The water quality in many areas of the inshore Great Barrier reef remains poor principally because of poor farming practices, reducing the capacity of the reef to recover after bleaching.”

Dr Unsworth added: “For the reef to have any chance of survival in the long-term, the water quality of the Great Barrier Reef region needs to improve through better farming practices, and global carbon dioxide emissions need to reduce rapidly.

Phil North at Dive Worldwide said some divers fear it “is not what it once was”, but all is not lost for the reef yet.

He added: “This having been said, the reef is vast. It is the largest living structure on earth that can be viewed from space.

“Not all of it is destroyed and there are some parts that are still quite beautiful.”

While the current bleaching event is undoubtedly a setback for the reef, Great Barrier Reef Foundation Managing Director Anna Marsden said the reef is a “resilient ecosystem” which can still recover.

She added: “We know that on mildly or moderately bleached reefs, there is a good chance most bleached corals will recover and survive.

“It’s heartening to hear that some of the key tourism reefs in the north and central areas are amongst those likely to bounce back from lesser levels of bleaching.”

NOAA’s Bogus Climate Scare: “Near-Annual” Great Barrier Reef Bleaching


Climate alarmists are back with a new and far-fetched Great Barrier Reef scare, just a few years after their most recent claims of massive coral death in the Reef proved false. No, alarmists, we are not entering a period of “near-annual” widespread bleaching.

Mark Eakin, coordinator of Coral Reef Watch at the U.S. National Oceanic and Atmospheric Administration, told the Australian edition of The Guardian that rising ocean temperatures may have pushed the world’s coral reefs into annual “mass bleaching” events from which corals can’t recover.

However, this year’s bleaching hardly qualifies as the “mass bleaching” Eakin describes. Even The Guardian acknowledged, “Many areas of the Great Barrier Reef are known to have experienced severe bleaching this summer, likely killing many corals, but others, including tourist reefs near Cairns and the Whitsundays, only experienced mild bleaching. Most offshore reefs in the far north escaped bleaching entirely.”

The reefs in the far north, which have “escaped bleaching entirely,” are the ones closest to the equator and thus in the warmest water.

"Climate at a Glance" provides a summary of the scientific evidence regarding coral reefs and climate change. The summary documents that corals have existed continuously for the past 40 million years, surviving and evolving in temperatures and carbon dioxide levels significantly higher than what exists today. Indeed, corals thrive in warm water, not cold water. Among the myriad factors thought to have driven recent coral bleaching episodes are, “oxybenzone (a chemical found in sunscreen), sediment runoff from nearby coastal lands, and cold temperatures like those recorded in 2010 off the Florida coast.”

Australian coral reef expert Dr. Peter Ridd recently debunked claims in 2016 that up to 93 percent of the Great Barrier Reef died during a bleaching event. “At the extreme, 8 percent died,” Ridd reported.

“There’s about the same amount of coral now as there was in 1995,” Ridd added.

“Of all the ecosystems in the world, in fact, the Reef is the one best able to adapt to increasing [temperatures], whether that’s natural or whether that’s anthropogenic. Half a degree temperature change certainly doesn’t cause mass bleaching events.”

Still other peer reviewed studies have indicated modestly warmer oceans cause an expansion of corals’ ranges. For instance, a team of Japanese scientists published a study in the peer-reviewed Geophysical Research Letters indicating corals off the coast of Japan expanded their range as water temperatures increased. The scientists, with access to 80 years of national records from temperate areas of Japan, found corals were expanding poleward as waters warmed, reporting, “[f]our major coral species categories, including two key species for reef formation in tropical areas, showed poleward range expansions since the 1930s, whereas no species demonstrated southward range shrinkage or local extinction.”

Like polar bears, coral reefs are doing fine

 
Corals are animals, actually closely related to jelly fish but of course differing in that they have a limestone skeleton made up of calcium carbonate. Their growth rates can be studied to give us knowledge of the ocean and its sea level over thousands of years.

They have lived throughout the oceans of our planet for many thousand years. Over those many years they have experienced both much warmer and much colder periods of geologic time. The bleaching that they have experienced in the view of many climate alarmists is not a sign of their destruction or in fact ill health. It is not a sign that the end of the world as we know it is in sight,

The simple truth is that when a coral experiences any number of environmental changes which could be the chemistry of its surrounding water or its local temperature, the algae that inhabit and feed a coral are likely to find the environment less suitable and leave for greener pastures.

The change in color of the coral which alarmists call “bleaching “ is a result of one group of bacteria leaving and then another group of bacteria taking its place. When the first resident group is leaving the coral becomes whiter and as a new group moves in the coral takes on a new color. This new color is often mistaken as the corals death knell. The algae that moves in not only provides it a new color but is also the corals source of the food it needs to live.

While the Polar Bear has been the face of the global warming delusion, coral reefs have been close behind as an animal that will eventually go extinct if we do not stop using fossil fuels, emitting carbon dioxide and warming the planet, its atmosphere and its oceans. The reality is anything but that.

The Great Barrier Reef, stretching 1400 miles along the coast of Queensland, Australia is also a prominent “poster child “ for the supposed damage mankind is doing to our Earth. It is actually composed of nearly 3000 separate coral reefs, can be seen from space and is perhaps Australia’s greatest tourist attraction. It’s ultimate destruction by man-caused global warming (now called Climate Change of course), is used regularly to pull at the heartstrings of those who sadly buy into the delusion.

In fact, it is probable that no reef has received greater scrutiny, and been the subject of more research than the Great Barrier Reef (GBR), especially since the clamor to save it hit warp speed.

The late Robert M. Carter, Emeritus Fellow of the Australian Institute of Public Affairs, who was considered the world’s leading expert on the reef, wrote extensively about it in Climate Change Reconsidered II: Biological Impacts. He explained that to quantify the trend in live coral cover of the GBR between 1995 and 2009, which the International Panel on Climate Change contends was the warmest decade and a half experienced by the planet in the past thousand years, annual surveys were performed. Marine biologists surveyed coastal communities each year on 47 reefs in six latitudes across about 700 miles of the GBR. They took samples at varying depths between 20 and 30 feet.

They found that coral cover increased in about half the regions and decreased in the other half as one would expect when nature operates without human intervention. Overall they concluded that coral cover was stable and that there was no evidence of “consistent system-wide decline in coral cover since 1995”.

Other research throughout the world has confirmed that corals are capable of reproductive activities under extreme environmental conditions. There is now a growing body of evidence to support the notion that corals inhabiting more thermally unstable habitats outperform reefs characterized by more stable temperatures.

In sum and a little more erudite: coral bleaching is an adaptive strategy for shuffling symbiont genotypes to create associations better adapted to new environmental conditions, as opposed to a breakdown of stable relationships that serves as a symptom of degenerating environmental conditions.

In the words of the late Robert Carter “the Great Barrier Reef is in fine fettle”.

New wave of coral bleaching raises concerns for Great Barrier Reef

Given the Greenie lies about the last bleaching  -- Peter Ridd won a court case over his criticisms of them --  this report is fit only to be ignored

Perhaps the most amusing part of the previous scare was when the Federal minister visited the reef to see for herself how bad it was.  She found it looked fine.  We read:  "The Great Barrier Reef Marine Park Authority has supported Environment Minister Sussan Ley's appraisal that the reef is "good" and has "a vibrant future"."

They completely walked back their cries of doom.  I guess not all Greenies are crooks but most of them seem to be



Another wave of coral bleaching is hitting the Great Barrier Reef as temperature levels surge above average.

The federal government’s lead reef protection agency on Wednesday discovered significant bleaching on three reefs in the far north of the world’s largest coral reef ecosystem.

“That is the first time we’ve seen significant bleaching so far this summer,” said David Wachenfeld, chief scientist with the Great Barrier Reef Marine Park Authority.

“It is a confirmation of our growing concern about what is happening out on the reef at the moment.” Heat stress that has built up on the far northern, central and southern parts of the reef over the summer has intensified over the last week. “These levels of heat stress are definitely capable of causing coral bleaching and we are now at a heightened level of alertness for what is happening out there in the park,” Dr Wachenfeld said.

A bleaching warning has been issued for large parts of the Torres Strait and far northern management areas of the marine park, where significant bleaching across multiple hot spots is likely.

Most of the area covered by the marine park was 0.5 to 1.5C above average as of February 11, with some central and southern parts being 2 to 3C warmer. “February is the hottest month of the year on the reef so these anomalies are really very concerning,” Dr Wachenfeld said.

The reef authority has been told of bleaching in other areas and is sending staff to survey the damage.

Further heat stress is expected over the next few weeks as temperatures remain high.
