Peter Ridd: Crying wolf over The Great Barrier Reef

Dr. Ridd points out that coral bleaching damage ‘looks terrible at first, but it quietly and rapidly grows back ready for the scientists to peddle their story all over again.’ Bad news is headlined, good news ignored.

The scare stories about the Great Barrier Reef started in the 1960’s when scientists first started work on the reef. They have been crying wolf ever since.

Scientists from James Cook University have just published a paper on the bleaching and death of corals on the Great Barrier Reef (GBR) and were surprised that the death rate was less than they expected because of the adaptability of corals to changing temperatures. It appears as though they exaggerated their original claims and are quietly backtracking.

To misquote Oscar Wilde, to exaggerate once is a misfortune, to do it twice looks like carelessness, but to do it repeatedly looks like unforgivable systemic unreliability by some of our major science organisations.

It is a well-known phenomenon that corals can adapt very rapidly to high temperatures and that if you heat corals in one year, they tend to be less susceptible in future years to overheating. It is the reason why corals are one of the least likely species to be affected by climate change, irrespective of whether you believe the climate is changing by natural fluctuations or from human influence.

Corals have a unique way of dealing with changing temperature by changing the microscopic plants that live inside them. These microscopic plants called zooxanthellae give the coral energy from the sun by photosynthesis in exchange for a comfortable home inside the coral. But when the water gets hot, these little plants become effectively poisonous to the coral and the coral throws out the plants turning the coral white – it bleaches.

But most of the time the coral will recover from the bleaching. And here’s their trick- they take in new zooxanthellae, that floats around in the water quite naturally, and can select different species of zooxanthellae to be better suited to hot weather.

Most other organisms have to change their genetic makeup to deal with temperature changes, something that can take many generations. But corals can do it in a few weeks by just changing the plants that live inside them. They have learnt a thing or two in a couple of hundred years of evolution.

The problem here is that the world has been completely mislead by scientists about the affect of bleaching and rarely mention the spectacular regrowth that occurs.

    “Quietly backtracking “ ?
    They should be offering an abject apology ++ to Dr. Ridd.

    And none of this is new knowledge. Back in the ’80s in grad school in south Florida I learned about why corals “bleach” and how they eject their symbiots and later replace them. So how did this nonsense that bleached corals are dead get started? If marine zoologists have been aware of the coral’s lifestyle, why is it now ignored by nearly all of them? This kind of scientific dishonesty is repellent, nothing more than a self-serving lie to try and grab more grant money to study a non-issue.

  3. Graeme No.3 says:

    I went on a school trip to the Great Barrier reef in 1962. The boat didn’t take us to the advertised reef but elsewhere. When I asked the leading hand why? he said “it’s lost colour, they do that. It will come back in 1 to 2 years”.

  4. pameladragon says:

    Snort! Once again, actual field observations put the lie to models!

    The GBR science has been metastasized by the spread of the climate consensus.
    The CC corrupts all aspects of science and society that is exposed to it.

    No Judge Available, Anymore, to Hear Peter Ridd Versus James Cook University
    November 5, 2018

    I’d been told that the case would be heard by Judge Jarrett, who presided over the proceedings earlier in the year. Now I’m told it’s all been cancelled, at least for the moment – and that Peter can wait until next year, that his case against unfair dismissal by James Cook University might be heard next year.
    – – –
    Ridd says in the GWPF report:
    A recent study of 400-year-old corals has found that bleaching has always occurred and is no more common now than in the past.

    Mentioning things like this can and does get your career cut short, it would seem :/

  7. hunter says:

    Climate concern is all about denial of observed measured reality in favor of a catastrophic narrative.

  8. Ve2 says:

    So basically the new report confirms what Peter Ridd said originally.

    The Great Barrier Reef fared better during an oceanic heat wave last year than during sizzling weather a year earlier that caused hundreds of miles of corals to bleach, according to a study published Monday that suggests the massive structure may be growing more tolerant to climate change.
