Climate Change causes record coral cover — What if we get too many reefs?

The new AIMS annual survey is in with the shocking result that not only was last year a record, but this year is even better. There is more coral cover on the Great Barrier Reef than ever recorded. We’ve had four bleaching events in the last seven years, and record hottest ever heat, the highest CO2 levels recorded since we invented ways to record CO2, and yet, despite all that, the reef is thriving.

In 36 years of measuring coral cover on the reef, it’s never been better.

Record coral cover for Great Barrier Reef: Australian Institute of Marine Science

Graham Lloyd, The Australian

The Great Barrier Reef has set a new record for hard coral cover over two-thirds of its 2300km length, results of the Australian Institute of Marine Science official long-term monitoring program show.

AIMS program leader Mike Emslie said the results were “good news” and showed that the Reef had “dodged a bullet” in bleaching this year.

“But the fact we have had four bleaching events in seven years is a major concern and highlights the impact of climate change here and now,” he said. “We are in uncharted territory and still trying to understand what this means.”

Or rather it highlights how irrelevant climate change is. If it had been a lowest ever year, they would have blamed climate change, yet when it’s a highest ever year, we still blame climate change as if great coral cover is a … bad thing?

Peter Ridd, of course, fearlessly speaks the truth and says the bleeding obvious — that we should have “a national celebration”:

“This brilliant result is proof that many science institutions have been misleading the public about the state of the Reef,” he said.

Bleaching happened in 2016, 2017, 2020 and 2022. The World Heritage Committee is still deciding if it should be listed as officially  endangered. Possibly we should worry that rampant coral growth might deprive us of bare ocean spaces in between.

Peter Ridd congratulates AIMS on its data collection, and they really do look like they are doing a good job. They monitor 87 reefs, do 3,888 mantra ray tows (as the technique is called) which covers 881 kilometers of reef. (See this video). They tow people along behind a boat over the same reefs each year and record the amount of hard coral cover. As long as the technique appears so comprehensive and honest, it appears to be public money well spent.

The worst recent bleaching was in the northern Great Barrier Reef, yet this section has the most spectacular recovery.

AIMS, Coral Reef Survey, 2022.

Yet defying all the odds, the Northern Reef has recovered so well.

AIMS, Coral Reef Survey, 2022.

And which marine biologists predicted this kind of recovery? How well do we understand coral growth if we cannot explain why these natural cycles appear to dominate and describe which factors are driving it?

AIMS, Coral Reef Survey, 2022.

AIMS, Coral Reef Survey, 2022.

Coral reef cover is not “everything” and as the AIMS spokeswoman suggests, diversity matters too. We know some kinds of corals (like Acropora corals) can grow rapidly, while others (like Pocillopora) are slower growing but survive bleaching better and replace the spaces left vacant by the death of others*. Perhaps the shifting species patterns are a problem, or maybe this is just the way it has always been. We do know that  corals already have the genes to survive another 250 years of climate change, that they can use epigenetic tricks to adapt to warmer and “more acidic” water and that the Great Barrier Reef has 112 protected tough spots that survive and replenish the rest after the bleaching. After millions of years of asteroids, volcanoes, wild temperature changes and dramatic shifts in atmospheric gases, (plus sea level swings of 125m!) we ought be shocked if corals did not have a full toolkit to cope with rapid changes. We know one vulnerable coral type adapted to ocean acidification in just 6 months, and that fish prefer to live in tanks which also have large daily CO2 swings in carbon dioxide.

We know that corals bleached all the way back in 1862, and probably have for millions of years, there were just not many scuba divers to record it.

This study is an absolute blockbuster in terms of busting the myth that corals are on the verge of extinction. Spread the word.

    And I understand the annual whale count of migrating whales moving north along the NSW coast and rounding Tacking Point has been very positive this year. The whales are counted on the same day each year and are making their way to the waters of the Reef. Steady growth over time of a healthy and growing population.

    So where is all the proof that the waters of the Reef are in a disastrous state?

      OK the big whales eat the littlest fish, they can’t catch mackerel, but you get my drift.

      There are two distinct areas of climate change evidence. Remarkable similarity of these events are easily seen when you realise there is one driving force behind them.

      Coral reefs are near extinction when Universities & other political & “study groups” can smell government “aid” in the form of $$$ by the millions or when some politicians need to boost their virtue signalling prowess.
      Then comes sea levels in the Pacific Ocean, which rise in direct proportion to the amount of $$$ of Australian tax payer funds on offer to “nations about to do a Titanic type sinking”.

      Another phenomenon is that of our politicians doing their best to destroy their own country.
      One must assume therefore that there is someone or something offering great rewards for perpetuating falsities OR that they are quite simply devious, immoral liars in search of credible virtues.

      There is a 3rd guilty party in this fiasco. The Media, the vast majority of which back the virtue signallers & the money grubs with their scientific ignorance aided & abetted by there obvious lack of grammar & even spelling abilities.

        “One must assume therefore that there is someone or something offering great rewards for perpetuating falsities”. Correct. The ever-greedy billionaires behind the renewable energy scam are the ones perpetuating falsities. They don’t care how many lives they ruin, or even how many countries they ruin. All they care about is more and more and more dollars flowing into their coffers. The source of this money is of course government subsidies and mandates for renewable energy, and the total is already well over a trillion dollars. That’s around $3,000 for every American person. And still the greedy bustards want more. Jail is too good for them.

      …the government(s) will take the credit for this recovery, which they will then claim is temporary.

      ABC Radio yesterday broadcast comments by one of the JCU researchers, who claimed that the variety of coral that was damaged is particularly susceptible but recovers rapidly and the concern was that the regrowth will be just as likely to be severely damaged by future extreme weather events (and just as likely to subsequently recover).

    They tow people along behind a boat over the same reefs each year and record the amount of hard coral cover. As long as the technique appears so comprehensive and honest, it appears to be public money well spent.

    I cannot believe this technique has been consistent over the long period that it has been used (starting in 1985 ?).
    Each divers assessments would be subject to their overall philosophical bias and that would be different under different narratives of climate change alarmism.
    And I expect that in more recent times there has been an influx of willing climate activists offering to be towed at minimal or no cost.
    Surely we are in for some “homogenisation” of the earlier manta tow data because the accuracy of recording will be questioned just like early temperature recording has been.
    Some type of coral-recognition software will be developed and they will quickly stop any manual recording in parallel to the “automated” procedure.
    This is the same as the changeover to automated temperature recording and we know that BOM have not overlapped those procedures like most serious scientists would.
    Now tell me this is not going to happen.

      “On page 9 of Peter Ridd’s new book ‘Reef Heresy’ it is explained that while the Australian Institute of Marine Science (AIMS) reports on coral cover, there are no direct counts of anything. Rather ‘observers’ are towed behind a boat from which they ‘estimate’ coral cover every few hundred metres.

      Peter makes the analogy of someone estimating people’s weight after standing on a street corner for some minutes and looking at everyone who walks past. There is no set of scales and no recording the identity of each person, and then calculating an average. What AIMS does is more analogous to observing everyone who walks past for 2 minutes and then writing down an overall guesstimate weight.”

          They are looking at the same set of reefs for 36 years. 844 kilometers. Yes, I would prefer some more objective technique, but it sure beats a few random photos, or shots from a plane. Repeat recordings for 36 years in the same spots makes it better than most BOM thermometer sites, where both the instruments, box, location, and raw data have changed in the last 36 years.

            With all of the money being spent and I wonder where that 444 million dollars that Malcolm Turnbull apparently authorised to be ‘granted’ to a GBR mob went? There could be underwater drones fitted with cameras to patrol the GBR with all images collected at a Central Control Centre and recorded for posterity. How come the ‘Clever Country’ is not on the case here?

            There seems to me to be a serious lack of use of technology here vis a vis all of the Taxpayer dollars being allocated (and likely being misused).

            At the very least, there needs to be an Auditor General review of how that 444 million dollars was allocated and eventually wasted – Err, I mean spent.

    OK, It’s all good, but a reef is a precious thing and can’t just grow out of nothing so the header is crap.

    I put it to you that if a reef which towers out of the depths “collapses” then that reef will NEVER grow again, like the Seven oops Six sisters off Great Ocean Road. Once gone ……

    I am as pleased as anyone that the reef is regenerating but don’t get smug, neither Ridd nor Marohassy are old enough to have seen the GBR in its splendour before the COT invasion. I am now too old [and there are no day trips anyway] to check out its health. I went on the last day trip out of town and thought what I saw was awful.

    It will take another 50 years to truly regenerate. Don’t drop your guard, GW is not the only threat. If you think that you are a fool.

      My memories of the Reef go back to the late 60’s and early 70’s – not as long as you Hanrahan but a fair slice. Fringing reefs at Green island, Hook and Daydream further south seem to be stable to me. There are many factors. Perceptions over time can be difficult.

      ONLY reefs that can possibly physically collapse are the atoll-type one perched on top of extinct / dormant mid-ocean volcano “cinder comes” The biggest one i have visited is Kwajalein. Interesting place.

      If my dive experiences on the GBR are any guide, the ‘reef” is well and truly footed on solid substrates of the continental shelf.

      Furthermore, there has CLEARLY been massive vertical movement of both ocean levels AND reef “beds” since the coral polyps decided to settle there.

      There ids NO way for coral to get enough light to survive at the depths of many of these “footings. Not enough of the right sort of light to let the zooxanthellas do their thing. Coral ‘polyps” are tiny beasties related to jellyfish and they contain these algae-like plants within for “mutual benefit”.

      ALL of this action is taking place on the Australasian Plate, which has been steadily trundling North-West-ish” for many millions of years.Three guesses why the huge island of Sumatra is “kinked away from Java at a funny angle? An supplementary guesses as to what that kinking” did to the geomorphology of the Sunda Strait and adjacent land? The whole planetary “rock-show” (literally) is NOT set in Gaia’s home-brew “aspic”; it is a HUGELY dynamic system.

      Australia used to be a hot-bed of vulcanism. Think about the Undara lava tubes, crater lakes Eacham and Barrine, between 10,000 (Pleistocene) and two million (Pliocene) years old, the Glasshouse mountains, the mega-caldera that is the bed of the NSW Norther Rivers district, sites extending this all the way south to Mount Gambier. Never mind the several ACTIVE volcanoes in Antarctica.

      The early explorers in Oz went into the Never-Never seeking the “Inland Sea”. Right idea, just a hundred million years too late.It is the underlying geology that drive so much.

      Hanrahan,

      Very few people have been to the Outer Reef, where the reef meets the wide Pacific Ocean. It is mostly several tens of km offshore. We have tried several times to get there, but weather stopped several planned amphibious flight hires and some fast boat trips. Never did see the full beauty. Not able to comment much on blogs because I lack the observational authority.

    After millions of years of asteroids, volcanoes, wild temperature changes and dramatic shifts in atmospheric gases,…

    I think to this list should be added the very obvious dramatic sea level changes. I don’t remember the exact figure offhand, but sea levels rose something like 120-140 meters since the younger Dryas. Just sayin’…

    70

    • #
      John Hultquist

      The rise of 120-140 m. began about 20,000 ybp while the Younger Dryas was 12,900 to 11,700 ybp. Charts of post-glacial sea level do show the pause of the return to glacial conditions, that being the Younger Dryas, and then another 60 m. rise to the recent slowdown about 7,000 years ago.

        Thanks for the clarification of a minor point that I think was clear in my post that I wasn’t completely sure about the dates, etc. The larger and more important point that I was trying to make was that corals not only survived millions of years of environmental disasters, but also survived/came back from major changes in sea levels in the very recent past.

        It was intended to lend support to the idea that corals “have a full toolkit to cope with rapid changes,” not a scientific treatise on post-glacial sea level changes and timing.

      Phil, If you search on the age of the reef and sea levels at the time I think you’ll find that the sea was far lower then than now, coming out of the ice age. So much so that the GBR where there is 50m of water would have been shallow fringing reef which grew upwards as the sea rose forming bommies. This will can not be repeated so what we have is all we’ll ever have. New reefs can form in the shallows of course but not in 50m.

Some things cannot be repaired when the wicked global warming grafters attacks are so viciously damning and false. But, any restored justice and fairness would be of great help.

    Ohh The Barrier Reef.

    For decades it has been predicted by “experts” of its impending demise.
    I remember an article published by the “The Sun” Newspaper in the early 1980’s That the Crown of thorns was going to decimate the reef within a few years.
    None of the doomsaying reports have resolved to be true.

    In the southern hemisphere, Coral can be found at Lord Howe Island. Water temperature 18-23 degrees Celcius.
    Dive there, I recommend it.

    Indonesia has thousands of coral reefs, I have hit enough of those whilst surfing there for 30 years.
    The coral is fine and healthy, though I report my body was not on several occasions…. as coral inside a human is not pleasant.

    The seawater temp can reach 31 degrees celcius in the Indonesion islands.

    Now our maligned Barrier Reef middles those latitudes.
    The water temperature range sits between those of Lord Howe and Indonesia.

    I have dived on the length of the Barrier reef scores of times over the last 3 decades. It is the same, same beautiful.

    I wonder though, there are coral reefs off the coast of Western Australia… Why are they never mentioned in a scientific report?

    Of all the thousands and and countless thousands of reefs around the world
    Why is it that that The Barrier reef is the one to fearmonger over?

    I think every one needs to chill.. The Barrier Reef is fine. Coral is a living organism. It recovers just like I do.

    Do yourself a favour and dive the reef.

    Important Postcript:
    (I must confess. I only recover from any heavy contact with a foreign coral reef…
    When I have painfully removed said coral from my body using an antiseptic, knife, forceps and a toothbrush to srub and clean the wound. Take my advice, It really hurts.)

    The southern part of the Reef has not done too well. Best keep the GBR in context. Overall, the Reef is thriving. The idiots who state that AGW is the cause of the Reef dying is laughable. The principal factor of the Reef’s future is the PH of the ocean, not a few extra CO2 molecules in the atmosphere.

          Sounds like a British comedy skit comparing the housing conditions of the impoversished class. “You had a cardboard box?”.
          I first dove the Bruce Highway Townsville to Brisbane about 1958. Crashed doing it 1961, lucky to survive.
          Those days perhaps half that length had bitumen.
          Corrugations play hell with the leaf suspension/friction shockers of a 1949 MG TC. Potholes simply snap springs. Kidneys get pain.
          The locals talked of the “Sarina-Marlborough stretch” with fear that was earned. Windscreens can break when rocks hit them.
          Some seasons, you could see a dead wallaby roadkill as frequent as one for every kilometer. We used to make a game to stifle boredom, spot the dead wallaby before the odometer flips to another km or another mile before 1966.
          Memory lane. Some stuff is best to forget. Geoff S

      Whenever I have heard reports of the “acidification” of the ocean,I have looked at the numbers. What they reveal is probably a reduction in alkalinity because sea water is usually the alkaline side of neutral anyway .Seawater pH naturally fluctuates between 7.66 and 8.4 within decades and is buffered. The word “acidification” is used to scare us- people think “oh no, battery acid type conditions”. It’s not.

      Malcolm… gift of… $444 million to Lucy and friends

      (Don’t paint Malcolm as generous please, it was our money he gave away, and without our permission)

      Maybe that began the resurrection of the reef, but remember, “post hoc ergo propter hoc”, It was the ascension of Albo that caused the report of the reef’s resurrection.

    It’s amazing how there is no problem with the Reef now that the Labor regime is in power federally.

    Plus as TdeF mentioned above, Turnbull’s unexpected “gift” of our hard-earned taxes to the twelve members of the GBR Foundation who found about about this massive wealth transfer to themselves via the news, not a formal communication.

    Now there’s no problem, are they going to give the remains of the money back to taxpayers, assuming there’s anything Left? I didn’t think so.

    No matter whether The GBR is in fine fettle a Labor Environmental edict, no doubt to pacify Greens ambitions has cancelled Clive Palmer’s new coal project in the Bowen Basin that is 100’s of km distant from the coast, on the grounds that it might pollute the GBR.

      Why are the Left opposed to that?

      That coal will only benefit the Chicomms, Australians aren’t allowed to use it. So the Left should be fine with that.

      Chicomms, the world’s largest CO2 emitter by far, have no emissions limits and absolutely no complaints from the Left about their “carbon pollution” (sic).

    There are some interesting comments and links here about the tolerance of coral to natural changes in pH, including normal natural daily changes.

    Even if ocean pH was changing as claimed, and those extreme claims seem to be not supported by fact or even possible, corals are not being destroyed by supposed anthropogenic changes in pH.

        <strong, eucalypts are "invasive"; they out-compere fluffy rain-forest types after a fire.

        They also change the soil by te constant shedding of thei leaves and bark. The result is a Podzol type soil that is not so conducive to the growth of other tree types. Furthermore, most eucalyptus species of my acquaintance ere "fire-climax" types; i.e., the scattered seed pods are seriously tough and require a quick once-over from a fire to "crack" the pods for germination.

        Serous players in the great outback.

        As many Australians have long known and Californians are slowly learning, a serious fire in a dense eucalyptus forest is not to be welcomed.

        For those wondering how they got to California; back in the late 19th century some enterprising types identified several species as being ideal for wharf pilings and such. So, they imported a bunch of seeds and went to work. Interestingly, by importing seeds, they planted forests of "exotic" vegetation that had NO predators, parasites or disease that usually take their toll. What took a while to discover was the exciting potential for catastrophic fires. Fires that are such that they create their own "weather"; with self-generated local winds driving crown fires and huge clouds of hot embers before it.

        Given recent events here in Oz, I suspect the tree-huggers and feral bureaucrats have systematically "memory-holed" that information with one hand whilst stretching out their other hand for "grants".

        Peter Fitzroy

        yes David, that concept still exists, but here we are talking about existing communities, comprising both hard and soft corals growing on a substrate that is close to the water surface (1-10 metres depth) The bleaching events affect some species more than others, but there are always some that survive, they are just hard to see. Do not be misled by the photos showing only bleached coral. The GBR is special because of the diversity of coral species contained within it. The change hard coral growth in the northern and central sections is good, but it is at the expense of other species, which is new.

    They are still slaughtering the crown of thorns starfish and have even developed a hunter-killer robot to do this.

    How can they claim it is an introduced species when their larvae float freely on the oceans and can colonise anywhere the ocean currents take them?

    It looks like the predictions in Requiem for the Reef (1976) and Crown of Thorns: The Death of the Barrier Reef? (1972) never came true, eh?

      Yep, and soon someone at the UN will claim they’ve halted climate change/ global warming because the earth’s temperature hasn’t really increased at all over the last 20 years. They’ll be saying if it wasn’t for all those CO2 emissions agreements, the level of CO2 would have already climbed to 600 ppm (or whatever ). Remember they cured the Hole in the Ozone Layer – not, it’s still there, just changes in size depending on seasons and probably some other unknown factor.

    I don’t know whether that claim is true or not. NEVER believe a “scientist” that earns money via the Klimate Kult. But assuming it was true, THEN:

    They don’t teach real biology or science in general anymore but back in the day there was this idea that the species that first colonised a barren or previously devastated biodiverse area were called pioneer species. After they were established, others would follow and the mix would change. That will happen at the GBR as well.

    Never forget that during the warmer Holocene optimum sea levels on our Aussie east coast were about 1.5 metres higher than today.
    See ABC Catalyst “Narabeen man” and many studies quoted and linked by Ken Stewart’s excellent posts.
    The warmer Holocene optimum lasted for thousands of years and co2 levels were about 280 ppm at that time and the GBR had to survive warmer temps compared to the 20th and early 21 st centuries.
    BTW Peter Ridd is a quiet hero and he should be re-hired and compensated ASAP and all the other con merchants and so called scientists should be sacked.

    Could it be that certain people are starting to realise that the lies of anthropogenic global warming are unsustainable, even among a totally dumbed-down population and this “miracle” of reef recovery is a construction to give the promoters of the anthropogenic global warming fraud an easy way out?

    Might further “miracles” and discoveries follow to show that the “climate emergency” is over?

      Hanrahan

      There have been no big floods in Nth. Qld. in the last couple of years.

      If run off was a big problem the reef out from the Burdekin would be suffering badly because it drains so much cattle country and some graziers have allowed too much erosion and cow dung runoff.

      But excess nutrient would promote algae which would choke coral. I am unaware of any algae problem. I suppose that would be “coral greening”.

      Remember the GBR is 70 km from the coast, plenty of time to get sea sick on the way. 🙂

    Here Ken Stewart lists numerous studies of the much warmer Holocene optimum along our Aussie east coast and he accurately calls this the world’s biggest thermometer.
    Of course our previous Eemian inter-glacial was much warmer than our present Holocene and the Co2 Coalition site claims it was up to 8 c warmer at that time.
    YET our GBR survived that much warmer period as well.
    And AGAIN co2 levels during the much warmer Eemian were about 280 ppm. THINK about it and WAKE UP.

      Not sure about that 8℃ claim as it may have been 2.5-3℃ warmer. Ocean levels seem to have been 6 metres higher than present but there was a claim that massive tectonic uplift in the Caribbean might have had an influence.

        BTW fully evolved modern Humans are now thought to have existed for at least 200,000 years, yet about 10 years ago the estimate was only about 100 to 150 K years.

          Neville:
          I read that as a claim, not that the whole earth became 8℃ warmer. Could that be 8℃ warmer in Greenland? Nothing unusual about that – temperature rise after the Younger Dryas for example.
          The estimate for the existance of modern human is around 210K years in East Africa but 270K for possible types in West Africa (Algeria way). But judging by recent political behaviour I think that some of the population is lagging behind.

          From the website of “Industrial Relations Claims”. A law firm. Affiliated with the “Supportah Network”

          Re the case of Peter Ridd.

          Quote:

          “The confidentiality of all parties involved in the management of Misconduct and Serious Misconduct processes will be respected and all information gathered and recorded will remain confidential…
          However, Ridd failed to keep his mouth shut. Instead, he once again publicly criticised JCU for taking action against him. He even launched a public fundraising campaign to pay for legal fees.”

          End quote.

          Ok, That is a public comment from the law firm mentioned above.

          As someone that investigates and supplies reports to the NSW coroner. I cannot comment on the extract above.
          I provide evidence to the court that cannot be compromised by perceived prejudice.

    Citizen researcher Willis Eschenbach who often reports at WUWT has a skill for producing global graphics from satellite data. The one pertinent to the reef bleaching/recovery cycle is his movie of the 1997/98 Niño/Niña ocean water pumping cycle, showing that satellite-measured sea levels can change by ±0.3m on either side of the Pacific Ocean depending on the state of the Niño/Niña cycle. Eschenbach’s Figure 2 movie is fascinating – sea levels in the Gulf of Carpentaria are particularly susceptible to the Niño/Niña cycle, but stop the movie at about 6 seconds and note the “blue blob” of -0.3m water level sitting on the reef.

    You could dismiss ±0.3m variations as inconsequential, but then have a look at Figure 6 in the paper “Climate Drivers of the 2015 Gulf of Carpentaria mangrove dieback“, where the satellite determined drop of -0.3m (about 16 secs into the movie) matches with a -2m anomaly in figure 6. The rise/fall in sea levels in the reef area may not be as great, but may be enough to affect the corals.

    Wouldn’t it be good if some of those GBR millions in research money were spent on producing sea level graphics similar to Eschenbach’s to help find out why the coral die-back occurred during la Niña years – were the corals actually exposed in places as well as affected by warmer waters?

    Science is built on observations. The science is made better when either the number or period of time increases for those observations. The period of time of intense observations of the GBR is too short. It’s only been happening since about the 1970’s. Hence, there is no reliable context or perspective to compare to. The same is happening at the moment with the CSIRO and their expeditions to the Southern Ocean to observe “climate change”. They have just barely started these expeditions on a regular basis ( annually ), but already they claim to be observing signs of climate change. Its ridiculous, when CSIRO has made at least 50 expeditions – perhaps then, make some careful comments. The other problem is their claims cant really be challenged because they are the sole owners of the data.

    The total recovery of the Great Barrier reef teaches a few absolute lessons

    It was never true. Science does not contradict facts. Facts contradict science.
    The recovery was not man made. The damage was not man made.

    We now know bleaching happens but the reef comes back to full health.
    This is also known to be true for the Crown of Thorns starfish which is celebrated in Tahiti as a welcome event which improves the reef. Like pruning.

    The bleaching was used as absolute proof of culpability, liability, poor management and UNESCO determined that the reef was in real trouble and Australia was the culprit.
    We know this is true because Barack Obama said so.

    However if the reef has returned to full health, there is no Climate Change damage, no industrial or farm runoff damage. And no proof at all that such alleged damage was not cyclical or natural

    And in the long term of no consequence whatsoever. The reef is as good as it was decades ago, if not better.

    This gigantic North South reef is 2500km long and up to 250 km wide and reefs in the Pacific can be kilometers deep.
    This reef, comprised of many reefs stretches from the tropics to the temperate. And has been around in good times and bad
    including a few ice ages.

    Can we now stop fantasising about our alleged and clearly ridiculous duty of care?

    And it would be nice if also we stopped fantasising about how we control CO2 levels in the atmosphere.
    That is scientifically impossible.

    This is shocking, or would be in a sane world: Gina McCarthy, the Biden administration’s National Climate Advisor, is openly calling on tech companies like Facebook and Twitter to censor any dissent from the administration’s “green” fantasies.

      She later attended Tufts University, where she received a Master of Science combining Environmental Health Engineering with Planning and Policy in 1981.

    But now Christmas is Climate Change. And this year it will be a cold Christmas in Germany without Russian gas. What happened to catastropic rapid Global Warming. Surely they should just be grateful for the 1.5C since 1860? After all we have erected hundreds of thousands of giant windmills in honour of the Gods of Climate Change.

    And the Gods have returned the Great Barrier Reef, hale and hearty. It cannot possibly be natural. Like the Fall, it has to be someone’s fault. The Druids of Climate Change say so and forsooth they dress in Green but beware, they are false prophets. And it’s all about the profit.

      True but consider a huge reduction in CO2 ’emissions’ is a dangerous measure, simply because that is not the alleged problem. So a drop in ’emissions’ cannot save anything, if their fantasy science was true and CO2 produced warming which somehow (not explained) produced ocean warming and this produced bleaching. (clearly irrespective of air or water temperature because they vary so much from one end of the reef to the other). So instantaneous Nett zero achieves nothing, zero, zilch, even in the logic of the Greens.

      The alleged problem is total CO2. And if human ’emissions’ were zero, CO2 is still controlled by the planet.

        Out of interest, do they have a lower limit of Co2 which would make the world too cold ? I’m aware of the plant limit for co2 but do greens have a limit in mind ?

        Could we theoretically return to earth at a time when co2 has been so sequestered that green policy is to burn as much coal as possible to heat the world up ?

          What does cold matter? We still have the tropics. But if CO2 fell to zero or even 0.02%, all life on earth would be extinguished quickly. Even humans would strangle, lacking the CO2 levels to trigger breathing. CO2 is so important to life, the gas from which all life on earth is made, that classing it as a toxic industrial byproduct is beyond science. It’s utter lunacy.

            Yes it’s 180 ppm that plants no longer function to my general knowledge. And this is planet of the plants. But back to the original point. It is, or is it an extraordinary stroke of luck that the earth is warming slightly just at the time when they come up with this theory of co2 ? A false correlation is feeding the whole idea.

              It was a theory by James Hansen of NASA as an expert on the climate of Venus. That makes it hard to get a job but he found an enthusiastic supporter in Al Gore who has made it his life’s work.

              The real driver was the World Meteorological Society who wanted to join the UN. But why would an organization to prevent war have an interest in the climate? So in 1988 this wacky theory was needed for all the world’s nations to join together and prevent a climate Catastrophe. The Intergovernmental Panel on Climate Change was born on the basis of this one theory and immediately found that it was correct and that all the nations of the world should wage war on Carbon Dioxide, an enemy greater than all the weapons of the planet.

              And on 28 June 1988, mid summer Al Gore and James Hansen climbed up into the roof of the Congress to open all the windows to defeat the air conditioning and so make a passionate case for rapid Man made Global Warming.

              Except it’s not true.

              But think of the tens of trillions of dollars. Even Al Gore is now a billionaire with many houses private aircraft. James Hansen has had the career he really wanted without having to worry about Venus. And the communist Greens could claim moral superiority over the greatest existential threat to humanity in history.

              Coincidence. No. Just opportunity, if you have no scruples at all. That’s the Inconvenient Truth.

    I had a look at the report and read that in a 200m tow, the diver has to record 7 parameters:
    1. Percentage hard coral cover
    2. Percentage soft coral cover
    3. Percentage hard coral bleached
    4. Number and size of crown-of-thorns starfish
    5. Number of coral trout and sharks
    And from the images, the diver has no obvious device to make any records on the spot.

    How does the diver record this information?
    Do we know if the diver emerges from the water after each 200m tow and correctly transmit the data to the scientist in the boat?
    Is there a recording device with the diver?
    People can be trained to memorize effectively, but I’d really be interested in the error bars around these observations.

    Also, these percentages would be estimates or guesses. Do we know how precise these estimates are?

    Some observations, some pedantry for future correctness.
    The ray is a Manta Ray, not a Mantra Ray.

    Dr Bill Johnston has calculated that temperatures along the Great Barrier Reef in a scientific survey in 1871 are quite similar to the temperatures that AIMS measures now. That is, there might not have been any detected warming of the waters over the last 140 years.
    See his blog at Bomwatch.org

    This month, August 2022, marks 10 ears of no global warming over Australia as indicated by the well-known satellite data from UAH, University of Alabama at Huntsville, working with bodies like NASA. Geoff S

      Geoff, you are right about the name of the fish, but consider:
      “a mantra is a sacred utterance… believed by practitioners to have religious, magical or spiritual powers” (Wikipedia)

      Thus I picture a “mantra tow” as being a greenie fanatic being towed along over the reef while chanting ” — climate change — carbon pollution — global warming — “

    Well if it was me charged with tackling the COT “problem”, I’d train dolphins in the task.
    Being such intelligent creatures they could be trained to target COTs with a custom designed fixed-dose syringe vinegar set-up.
    A back mounted reservoir and a quick jab…
    They could do it all day long and cover a sizeable territory. Distributed tank replenishment points to maximise efficiency.
    A free feed of fish at the end of the day and they’re happy. Sounds good to me…

    Now about that $400 odd million that Malcolm Turnbull sent to some inauspicious GBR Research Group.
    Certainly seems to have worked. Maybe they could return the unspent money now that everything is OK.

    ‘more acidic water’

    These liars can’t help themselves can they. The water is not acidic in the first place and can’t get more acidic.

      It’s a word game. Decreasing pH is heading in the direction of acid, which is called therefore ‘acidification‘ as in ‘ocean acidification’. To make the ocean acidic would require the dissolution of all shells, limestone around the world, like the white cliffs of Dover. All the reefs. In fact the land under England and Paris and Odessa and more. So it’s all a game of words.

    The reef recovery is extremely significant from a political perspective as largely neuters the politics of the”dying reef.
    From a reef scientists point of view it is disastrous as it threatens their gravy train. I am sure 98% of reef scientists have just been proven wrong?
    From a biological perspective it is even more interesting as the rapid recovery demonstrates the power of Mother Nature. In this respect it also challenges the assumption that “all bleaching /reef damage is bad. In fact it could be argued that regular removal of a percentage of reef biomass permits and encourages new growth which responds in the context of the modified (if that is the case) environment . After all isn’t that how nature works?
    Perhaps Crown of thorns infestations , cyclones and bleaching events are intrinsic to a healthy sustainable reef
    As in Climate Science we need to ‘reboot’ and start looking at these issues from a broader perspective.

    @Jo Nova
    Has this been mentioned yet?

    Three lessons from a massive research misconduct case in marine science. Yesterday, Science magazine reported that the University of Delaware “found one of its star scientists guilty of research misconduct.”

    Professor Dixson and her collaborators, including her PhD supervisor Philip Munday of James Cook University (now retired) in Townsville, Australia, have published dozens of papers suggesting very large and ecologically harmful effects of increasing carbon dioxide on fish behavior.

    Several years ago, a separate group of researchers led by Timothy Clark, of Deakin University in Australia, expressed concerns about the integrity of this research.

    An interesting side note here is that the allegations of fish research misconduct reach to James Cook University (where Prof. Dixson’s PhD supervisor recently retired from). You may have heard of James Cook University in another controversy — that involving marine researcher Peter Ridd, who lost his university job as a consequence of questioning the scientific merit of research suggesting that the Great Barrier Reef was in terminal decline
