Peter Ridd: It’s the science that’s rotten, not the Great Barrier Reef

by P. Homewood, Dec 7, 2020 in NotaLotofPeopleKnowThat


The International Union for Conservation of Nature has released its latest report on the state of the Great Barrier Reef. It has turned up the volume by one notch, claiming the threat to the reef has gone from “significant concern” to “critical”. It blames climate change, agricultural pollution, coastal development, industry, mining, shipping, overfishing, disease, problematic native species, coal dust — you name it, it is killing the reef.

But the report is just a rehash of old, mostly wrong or misleading information produced by generally untrustworthy scientific institutions with an activist agenda and no commitment to quality assurance.

It is remarkable that the world has been convinced that one of its most pristine ecosystems is on its last legs. Part of the problem is that, being underwater and a long way from the coast, very few people visit the reef. The truth is hidden. Those of us in North Queensland living adjacent to the reef, and tourists from elsewhere, can report the water is iridescent clear blue and totally unpolluted. The fish and coral are fabulous.

Measuring Old Corals & Coral Reefs (Part 1)

Fundamental to science is measurement. It is a way of objectively assessing something, anything, even the state of a coral reef, even of an individual coral. Historically coral growth rates were measured by coring the really old massive Porites.

Like tree rings in temperate forests, the massive old Porites can be cored to see the banding and from this it is possible to calculate coral calcification rates which are a measure of the growth rate of individual corals.

Peter Ridd has been asking for some quality assurance of so many of the measurements relating to Great Barrier Reef health, including coral growth rates. Key Australian institutions have responded by stonewalling, and in the case of James Cook University, actually sacking him. After two rounds in the federal courts his appeal against his dismissal is finally going to the High Court of Australia, with the next hearing probably in February 2021. While the lawyers are preoccupied with Peter’s rights, or otherwise, to academic freedom and freedom of speech, my concern is whether Peter is actually telling the truth when he says that the Great Barrier Reef is resilient and definitely not dying from coral bleaching, though there is a problem with the integrity of the science.

The scare stories about the Great Barrier Reef started in the 1960’s when scientist 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.
