The next ‘Ferrari of shale’ may be hiding in Australia’s outback

by Bloomberg Business,  May 3, 2019, in theJapantimes


In a corner of the Australian Outback, a drilling crew will soon try tapping shale rocks that could hold more than three times the world’s annual consumption of natural gas.

Origin Energy Ltd. plans to drill two wells later this year in the Northern Territory’s Beetaloo Basin, after the local government ended a three-year ban on fracking — the practice of extracting oil and gas from layers of shale rock deep underground. With an estimated 500 trillion cubic feet (14 trillion cubic meters) of gas, Beetaloo has been compared to famed U.S. shale regions such as Marcellus and Barnett.

But its isolated location, lack of infrastructure and the likelihood of tough environmental opposition make Beetaloo a highly speculative investment.

“There are some big numbers being quoted, and people have to realize this is exploration,” said Mark Schubert, Origin’s head of integrated gas, noting that only some of the total reserves would be extractable.

Australia Surface Temperatures Compared to UAH Satellite Data Over the Last 40 Years

by Roy Spencer, April 3, 2019 in GlobalWarming


Summary: The monthly anomalies in Australia-average surface versus satellite deep-layer lower-tropospheric temperatures correlate at 0.70 (with a 0.57 deg. C standard deviation of their difference), increasing to 0.80 correlation (with a 0.48 deg. C standard deviation of their difference) after accounting for precipitation effects on the relationship. The 40-year trends (1979-2019) are similar for the raw anomalies (+0.21 C/decade for Tsfc, +0.18 deg. C for satellite), but if the satellite and rainfall data are used to estimate Tsfc through a regression relationship, the adjusted satellite data then has a reduced trend of +0.15 C/decade. Thus, those who compare the UAH monthly anomalies to the BOM surface temperature anomalies should expect routine disagreements of 0.5 deg. C or more, due to the inherently different nature of surface versus tropospheric temperature measurements.

Conclusions

The UAH tropospheric temperatures and BOM surface temperatures in Australia are correlated, with similar variability (0.70 correlation).
Accounting for anomalous rainfall conditions increases the correlation to 0.80. The Tsfc trends have a slightly greater warming trend than the tropospheric temperatures, but the reasons for this are unclear. Users of the UAH data should expect monthly differences between the UAH and BOM data of 0.6 deg. C or so on a rather routine basis (after correcting for their different 30-year baselines used for anomalies: BOM uses 1961-1990 and UAH uses 1981-2010).

The ‘trick’: How More Cooling Generates Global Warming

by Jennifer Marohasy, March 5, 2019 in WUWT


The Bureau of Meteorology has rewritten Australia’s temperature in this way for the second time in just six years – increasing the rate of warming by 23 percent between Version 1 and the new Version 2 of the official ACORN-SAT temperature record.

Temperatures from the Rutherglen research station in rural Victoria are one of the 112 weather stations that make-up ACORN-SAT. Temperature have been changed here by Blair Trewin, under the supervision of David Jones at the Bureau.

 

Annual average minimum temperatures at Rutherglen (1913 to 2017). Raw temperatures (green) show a mild cooling trend of 0.28 degrees Celsius per 100 years. This cooling trend has been changed to warming of 1.7 degrees Celsius per 100 years in ACORN-SAT Version 1 (orange). These temperatures have been further remodeled in ACORN-SAT Version 1 (red) to give even more dramatic warming, which is now 1.9 degrees Celsius.

CORAL REEFS CAN TAKE THE HEAT, UNLIKE EXPERTS CRYING WOLF

by Peter Ridd, December 26, 2018 in GWPF


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.

 

‘Glimmer Of Hope’ For Great Barrier Reef As Study Shows Tolerance To Climate Change

by Nick Visser, December 10, 2018 in Huffpost


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.

Coral Adaptation and Epigenetics

by Rud Itsvan, November 17, 2018 in WUWT


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).

Evidence of the Medieval Warm Period in Australia, New Zealand and Oceania

by S. Lüning, January 9, 2018 in WUWT


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, …

NT has gas for hundreds of years: Canavan

by Australian Associated Press, September 5, 2018 in DailyMail


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.

King Coal rules Australia again–Booker

by P. Homewood, September 2, 2108 in NotaLofPeopleKnowThat


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.

Drought Proofing a Dry Continent

by Viv Forbes, August 16, 2018 in WUWT


Sensible drought-proofing policies for Australia are simple –

  1. Stop wasting water
  2. Build more dams, pipelines and pumps
  3. Build power stations capable of delivering cheap reliable electricity for pumping water and energising desalination plants.

Remember when they told us coral bleaching was a sure result of recent man-made global warming? Never mind.

by Anthony Watts, August 17, 2018 in WUWT


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.

Marc Hendrickx writes:

New paper shows coral bleaching in GBR extending back 400+ years.

It’s on. Abbott dumps Paris, speaks science and ramps it up against Turnbull

by JoNova, July 4, 2018


Nine years ago the Australian Liberals were on the verge of splitting. Turnbull was about to give the Labor Party a free pass on the Emissions Trading Scheme and sell Australia out to the EU. Climategate broke (thank you FOIA) and the party rebelled and tossed out Turnbull. Now, after three elections where the people voted No to carbon taxes every time they could, we have an emissions trading scheme, a Renewable Energy Target,  and one of the most crippling Paris targets of any nation. This is despite our rapidly growing population, huge distances and massive resources and the failure of almost every other nation to even achieve their Paris goals.  We are The Global Patsy, obediently sacrificing competitive advantage, GDP, and lifestyle – all so Julie Bishop and Malcolm Turnbull get invited to the right parties. Economic carnage in a glorious quest to make the weather nicer.

Coal, a dying industry, just became Australia’s number one export (again)

by JoNova, July 2, 2018


Coal is a dying industry, but luckily for the Australian economy, the rest of the world is not as smart as The Australian Greens and Labor Party and they are still buying it.

Coal is set to regain its spot as the nation’s biggest export earner amid higher prices and surging demand from Asia, sparking fresh calls from the Turnbull government for Labor to end its “war on coal”.

The Department of Industry, Innovation and Science figures show total coal exports are forecast to reach $58.1 billion in 2018-19, overtaking iron ore ($57.7bn) for the first time in almost a decade. (…)

Can Universities Lawfully Bully Academics into Silence?

by Jennifer Marohasy, June 19, 2018


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.
