The same modelers were predicting drought and letting their friends nail their reputation to statements about how the dams would never fill, and Perth would be a ghost town. When Australia wasted billions on desal, they said nothing about the “extreme rain” coming. Then the endless drought broke, the rains returned, and now, years later, they’ve rejigged and tweaked their skillless models and put forward ambiguous, vague, yes-no-maybe, scare-scare-scary predictions that could have come from a tarot card reader.
Get ready for the full genius of expert modelling:
“There is no chance that rainfall in Australia will remain the same as the climate warms,” said an author of the paper UNSW Professor Steve Sherwood.
“The only way that this intensification of extreme rainfall falls at the lower end of the scale is if the continent becomes drier overall. The long and the short of it is that with 2°C of global warming Australia is stuck with either more aridity, much heavier extreme rains, or some combination of the two,” said Sherwood, from UNSW’s Climate Change Research Centre.

The Fake Conversation where Bill’s informative, polite comments are removed, but the replies are left there.
Last week Bill Johnston posted a detailed, comprehensive analysis of Sydney Observatory thermometer record here that shows that most of the warming recorded there is due to buildings and freeways. But photo’s and graphs are “denier” stuff, and The Conversation is so afraid some its readers might see those historic photos they ban links to Bill’s work and joannenova.com.au. Apparently when the Bureau of Meteorology discusses “Australia’s hottest decade” it is off topic to discuss the condition of their thermometers.
Bill Johnston was happy to defend his work in comments at The Conversation, but Blair Trewin, who wrote the post itself, was entirely absent. Cory Zanoni had to close the dangerous thread. He removed scores of comments, but left replies to Bill Johnston intact. Some “conversation”.
At least 46 of Bill Johnston’s comments were deleted from Australia’s climate in 2016 – a year of two halves as El Niño unwound and 19 deleted from Australian climate politics in 2017: a guide for the perplexed. As Bill says: They obviously want to stay perplexed; uninformed; scary-cats, without a paddle for their leaky canoe.

Last week the Maroondah Reservoir, near Melbourne, was full. Thanks to Bob Fernley-Jones for a great shot, perfect for a weekend thread:

In 2009 things were dry, the drought was endless, and in a panic, billions were spent on desalination plants for Victoria (not to mention for Sydney, Adelaide, and Brisbane). Then the rains returned, the desal plants were mothballed. In Victoria alone, up to $18 billion will continue to be spent regardless of whether any water is used.
(Amazing what a desal plant can do for water storage. )
Water Storage two weeks into summer, Australia: Melbourne 72% | Sydney 91% | Canberra 98% | Adelaide 89% | Hobart 98% | Darwin 68% | Brisbane 75% | Perth 28% *
There is water overflowing from the full dam below. As Bob says: “Not the greatest overflow it’s ever been but positive, and its only part of an interconnected system that is currently a very healthy collective.”
In evolutionary terms, it’s a blink. Around 1200-1400AD a bunch of people bought a few domestic horses to far east freezing Siberia, where the temperature sometimes falls below -70. Somehow the horses have already become physiologically and genetically well adapted to the extreme climate. The panic-merchants would have us believe that the climate is changing “faster than evolution”, but biology and genes turn out to be amazingly flexible. (Who knows, maybe 4 million years of swinging ice ages has that effect on gene pools?)
DNA studies revealed that these horses were all derived from distant domestic horses, even though wild unrelated horses lived in the region til 5,000 years ago. This is pretty spectacular.
Dr. Ludovic Orlando: “This is truly amazing as it implies that all traits now seen in Yakutian horses are the product of very fast adaptive processes, taking place in about 800 years. This represents about a hundred generations for horses. That shows how fast evolution can go when selective pressures for survival are as strong as in the extreme environment of Yakutia.”
Analyzing the genomes shows that it’s not driven by mutations in genes as much as by changes to the regulatory [...]
The national conversation is all about “seeming” and “confidence”. Greg Hunt (Environment Minister) boasted that he stopped an investigation into the Bureau of Meteorology (BOM), and prevented “due diligence” being a part of a one-day wonder “forum”.
“In doing this, it is important to note that public trust in the Bureau’s data and forecasts, particularly as they relate to bushfires and cyclones, is paramount,” [Greg Hunt] said.
It used to be that public trust occurred when organizations were fully investigated, accountable, and found clean. Now “Public Trust” is apparently increased when there are no investigations, or only weak whitewashes. Either the public has got a lot stupider, or the media and ministers have.
Plenty of the self anointed (those who know more than the dumb punters) thought Hunt’s boast was a big achievement. Anthony Sharwood, News Corp journalist (oh for a “reporter”!), wondered if the government was paranoid for wanting to check the BOM. Perhaps next he’ll be calling for global corporates to figure out their own tax bill; who needs professional auditing, right — it’s just “paranoid”?
But the bad news for Hunt and the Bureau (and Sharwood) is that the Truth will out, the [...]
The book Merchants of Doubt, by Naomi Oreskes, was made into a box office bomb (it crashed). But, darkly, it has an ongoing life in our schools. Tony Thomas uncovers the push to put propaganda in front of children, dressed up as education. The director of the film tells the world that his aim is to stop skeptics from being broadcast on TV. (Because that’s what you do when you can’t win a fair debate eh?)
This film was never about science, but about doing exactly what it claims to “expose”. (It’s projection all the way down.) The real merchants of doubt are those that seed doubts about honest whistleblower scientists, using character assassination, namecalling, tenuous associations, innuendo and allusion instead of scientific arguments. They don’t find a scientific fault in anything skeptics say, but resort to twenty year old false tobacco smears.
What we need are resources for teachers to help students critically analyze propaganda like this. How do children spot what isn’t said? What clues do we see in this movie that reveal its anti-science, political nature? Is it that they don’t let their skeptic targets talk about climate science at all? Readers suggestions are welcome. How do [...]
The danger is in the definition
Ken Stewart has been diligent at trying to understand the Bureau of Meteorology (BOM) method for finding heatwaves. He’d heard BOM head, Rob Vertessy speak on ABC radio, declaring that heatwaves were the “number one cause of death” from natural disaster in Australia. Ken wrote to Vertessy repeatedly but for some reason, despite the deadly risk to Australians, Vertessy was unable to answer the question of how to define and estimate heatwaves. (Perhaps if the BOM had The Internet, he could have sent Ken Stewart this link, which Stewart has now found himself four months later.)
The Excess Heat Factor: A Metric for Heatwave Intensity and Its Use in Classifying Heatwave Severity, John R. Nairn and Robert J. B. Fawcett (2015) 
With these instructions Ken has now replicated the BOM results for the 2014 heatwave in Melbourne. He has also used the same technique on Marble Bar, Western Australia, and Mawson, Antarctica and found that potentially heatwaves are a killer danger to our Antarctic researchers, and if heatwaves kill, they’d be much safer in Marble Bar. For the record, Marble Bar is the place that had 160 days in a row [...]
Humans can adapt to live in locations where the monthly average is over 40°C, and as low as -50°C. That’s a 90°C range. The world has warmed by 0.9°C in 100 years (or less, depending on adjustments). This warming was so dangerous that global population only expanded from 1.7 to 7 billion.
Now, if the IPCC are right, we might heat up by another half a degree by 2100 — shifting those extremes from -49°C up to 41°C.
Prof. Andy Pitman, one of Australia’s leading climate scientists, responds to this risk with all the usual careful analysis we’ve come to expect from mainstream climate experts. Here’s another “children won’t know what snow is” type of Global Panic quote:
“I expect by 2050 … people just don’t go outside,”
– Professor Andy Pitman, director of the ARC Centre of Excellence for Climate System Science at UNSW.
So that’s the end of golf, surfing, and picnics then. Somewhat confusingly, he also said (in the same interview) that we won’t necessarily notice that extra warmth: “… because humans acclimatise to heat quite quickly”. This is what 95% certainty looks like in 2015, ladies and gentlemen — abject panic and [...]
Joy. It’s another profoundly unscientific “consensus” study. At least one person thought that the 97% PR figure was not enough, and that magic 99.9% would sway the crowds. As if there was even one fence-sitter sitting, waiting, saying, “97% was too low…”
For the herding type of human, “consensus” is magnetically convincing. Not so for the independent minds who have seen prediction after prediction fail. If a 97% consensus on a highly complex, immature science is difficult to believe, a 99.99% one is comic. More of the same unconvincing stuff will do nothing except set off the BS meter. This new study will sway no one. The supernatural purity of it will work against “The Cause”.
A consensus is the one and only argument of the unskeptical, and they are doing it to death.
One fan, James Powell, was so enthused he spent nine months reading titles and abstracts of 24,000 papers, and found only four scientists (4!) who didn’t agree with the consensus. Some 69,402 other scientists apparently endorse “the consensus” (whatever it is) because they used the terms “climate change”, or “global warming” and they didn’t also make a clear statement that it was false, or [...]
There is some major messing with data going on.
What would you say if you knew that the official Perth thermometer was accurate at recording minimums for most of time in October in the eighties, but 0.7°C too warm all of December, and 1.2°C too cool in January? Bizarrely that same thermometer was back to being too warm in February! Try to imagine what situation could affect that thermometer, and require post hoc corrections of this “monthly” nature. Then imagine what could make that same pattern happen year after year. All those weather reports we listened to in Perth in 1984 were wrong (apparently). And this bizarre calendar of corrections is turning up all over Australia.
Bob Fernley-Jones has looked closely at all the adjustments done to achieve the wonderful homogenized ACORN data, as compared to the theoretically “raw” records listed in Climate Data Online (CDO) on the BOM website. He can’t know what the BOM did (since they won’t tell anyone), but he knows the outcome of their homogenization. He was shocked when he noticed a strange square-wave pattern repeating year after year; he was astonished that there were corrections calendar month by calendar month, up and down, switching [...]
