Scientists from James Cook University have just published a paper on the bleaching and death of corals on the Great Barrier Reef 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 careless, but to do it repeatedly looks like unforgivable systemic unreliability by some of our major science organisations.
The very rapid adaptation of corals to high temperatures is a well-known phenomenon; besides, if you heat corals in a given year, they tend to be less susceptible in the future to overheating. This is 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 because of 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 through photosynthesis in exchange for a comfortable home inside the coral. When the water gets hot, these little plants effectively become poisonous to the coral and the coral throws them out, which turns the coral white — that is, it bleaches.

Last year’s oceanic heat wave wasn’t as destructive as one the year before, scientists said.
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.
The report in the journal Nature Climate Change analyzed how corals along the Great Barrier fared in back-to-back mass bleaching events. The reef ― a UNESCO World Heritage Site and the largest living structure on the planet ― was cooked by overheated seawater in 2016 and again in 2017, with images of sickly white coral horrifying people around the globe.

WUWT has posted several excellent articles by Jim Steele on how global warming alarmism uses corals as the poster child for warming and acidifying oceans, none of which is scientifically justified. A brief review follows, calling attention to a recently discovered additional adaptation mechanism not covered AFAIK by Jim Steele’s posts. The motivation for this post was triggered by a recent lunch with newish neighbor Charles the Moderator (CtM), and his sharing many wonderful underwater photographs of the coral reef he now dives frequently off Pompano Beach (same reef system as off Fort Lauderdale, just a few miles further north and more conveniently onshore).

The climate of the pre-industrial past is of greatest importance to the ongoing climate discussion. Current climate can only be understood when interpreting it in the paleoclimatological context of the past few thousand years. Until not too long ago it was thought that the pre-industrial climate was monotonous and constant. This idea was e.g. promoted by Mann et al. whose famous hockey stick curve featured prominently in the IPCC report of 2001. Over the last 15 years, however, a large number of studies changed this view by providing robust evidence for the existence of significant natural climate variability. Of particular interest are the past 1000 years which commenced with the generally warm ‘Medieval Climate Anomaly’ (MCA, aka ‘Medieval Warm Period’, MWP), that eventually passed into the ‘Little Ice Age’ (LIA), before returning to the warm climate of the current ‘Modern Warm Period’ of the 20th and early 21st centuries.
There have been controversial debates about the existence of the MWP, …

The Northern Territory holds enough natural gas to supply Australia for 200 years-plus and is comparable to the shale resources that have revolutionised the US energy sector, Resources and Northern Australia Minister Matt Canavan says.
Such abundant gas should enable Australia to reduce its current high energy prices, which were the fault of southern states preventing development, Senator Canavan told an NT Resources Week conference in Darwin.

Something so extraordinary has lately been going on at the other end of the world that, if it did not run so flatly contrary to the prevailing groupthink of our time, it would surely have made big headlines over here.
We may have gathered that there has been something of an earthquake in the politics of Australia, where the prime minister Malcolm Turnbull faced such a revolt by his Cabinet colleagues over “climate change” that he was eventually forced out of office, to be replaced as leader by Scott Morrison.
But the real significance of this has only now come to light with the unveiling by Australia’s new energy minister, Angus Taylor, of the country’s wholly new energy policy, which completely reverses that of the Turnbull government.

With the growing likelihood of an open party revolt and a leadership challenge, Australian Prime Minister Malcolm Turnbull has been forced into a humiliating backdown over his efforts to enshrine Australia’s Paris Agreement pledges into legislation.

Sensible drought-proofing policies for Australia are simple –
- Stop wasting water
- Build more dams, pipelines and pumps
- Build power stations capable of delivering cheap reliable electricity for pumping water and energising desalination plants.

From the “science eventually self-corrects” department, new science showing coral bleaching of the Great Barrier Reef is a centuries-old problem, well before “climate change” became a buzzword and rising CO2 levels were blamed.

Dr Peter Ridd has taken James Cook University to court protesting his sacking for what he says is, primarily, speaking-out about the lack of quality assurance in Great Barrier Reef science.
Dr Ridd spoke out initially about there being no quality assurance of Great Barrier Reef science – science that is arguably misused to secure billions of dollars of tax-payer funding. When the University tried to stop Dr Ridd doing this, Dr Ridd spoke out against University management – making all the documentation public including on his new website.

Over millennia, the reef has adapted to sudden changes in environment by migrating across the sea floor as the oceans rose and fell.
The study published today in Nature Geoscience, led by University of Sydney’s Associate Professor Jody Webster, is the first of its kind to reconstruct the evolution of the reef over the past 30 millennia in response to major, abrupt environmental change.
The 10-year, multinational effort has shown the reef is more resilient to major environmental changes such as sea-level rise and sea-temperature change than previously thought but also showed a high sensitivity to increased sediment input and poor water quality. (…)

A new study, published in Nature by serial reef alarmist Prof Terry Hughes, Director of the ARC Centre of Excellence for Coral Reef Studies at James Cook University, examines the link between the level of heat exposure from the 2015/16 super El Niño, “resulting in coral bleaching and ultimately coral death.“

h/t Geoff Sherrington – Coal is being rehabilitated as an essential component of the clean energy future.

Coal to hydrogen is not a new idea, the Water-gas shift reaction was discovered in 1780 by Italian Chemist Felice Fontana.
There are still some kinks to be worked out. The process to generate hydrogen from coal produces a monstrous amount of CO2 – far more CO2 per unit of useful energy than simply burning the coal would produce. But with hydrogen production, unlike hydrocarbon combustion, all the CO2 is produced in one place. This creates an opportunity for carbon sequestration, when technologies to sequester carbon on such an impressive scale are developed.
