Questions about the BOM spread: “Adjusted Temperatures Need Explaining” by Tony Cox in the Newcastle Herald. Jennifer Marohasy picks it up and draws attention to the situation of Newcastle temperatures, which were recorded at Nobbys Signal Station, near the Lighthouse at Nobby’s Head.
Old Trove archive records show that in the 1939 heatwave there were protests that Nobby’s Head temperatures were too cool to represent the real heat going on in Newcastle because it is exposed to good sea-breezes. (h/t to Siliggy)
The BOM page for Nobby’s links to this graph of the raw data.
The raw data from Nobby’s shows a hot period in the late 1880s. This is Climate Data Online or CDO.
Jen Marohasy points out that the BOM ignore this long record and use Williamston RAAF near Newcastle instead as one of the 112 stations to calculate national trends.
Note the trends…. adjusted of course.
Marohasy argues that the BOM ignore the better long record and use the shorter airport instead:

The sea ice around Antarctica is at a record high since satellites started recording, and snowfall is thumping down on the northern Antarctic Peninsula*, but alas — some glaciers on the same peninsula are continuing to melt, just like they have done for 300 years. Hence, a team of researchers-with-models conclude that this means these glaciers are especially, very, super-sensitive to air temperature changes and will “likely” melt fast, raise sea-levels, and disappear in 200 years time.
Glaciers in northern Antarctic Peninsula melting faster than ever despite increased snowfall
Increased snowfall will not prevent the continued melting of glaciers in the northern Antarctic Peninsula, according to new research. Scientists have discovered that small glaciers that end on land around the Antarctic Peninsula are highly vulnerable to slight changes in air temperature and may be at risk of disappearing within 200 years. – Science Daily
“Faster than ever!” Blame Climate Change TM:
[Prof Glasser]: “This unprecedented glacier recession, in response to climate change, will result in significant contributions to sea level rise from this and similar Antarctic Peninsula mountain glaciers and ice caps.” –Wales.co
Hmm. I note that other warming parts of Antarctica are near a string of volcanoes and (surprize) so is this one. Though some red dots are inactive or dormant.
The red dots on the map are volcanoes (up to 11 million years old). That includes the living and the dead ones.
The proximity doesn’t mean that volcanic or geothermal energy is melting the glaciers. But does anyone know if they aren’t? Dr Davies sweeping publicity suggests they can measure the geothermal heat flux under the ice and water. Call me unconvinced — rather than adding up the kilojoules, I don’t think we can even add up the volcanoes. It’s hard to tell what is going on under a km of ice. We seem to keep discovering new volcanoes — for example: like last May, and before that last November. As one researcher puts it, things are going swimmingly if you are a volcano researcher in Antarctica.
Prof Smilley describes the situation:

I trained in microbiology so I’ve watched the Ebola situation unfold with quiet dread. When my favourite lecturer was asked what was worst of the worst infectious epidemics he could imagine, he responded that the sum of all fears would be a cross between Ebola and Newcastle’s disease. It would be a highly fatal hemorrhagic disease, combined with a highly contagious virus spread by birds. It’s time to talk of the dark dark possibility that one mutation could bring — the aerosolization of Ebola.
As long as this Filovirus stays in its current form, spread only through direct contact with an infected and obviously ill person, we have a chance to limit the spread. Quarantine is effective. If it goes airborne, the task becomes like preventing the flu, but without clinically tested vaccines, in a totally unprotected population, and with a 60% fatality rate. This is the nuclear option.
The Ebola virus has several different forms, and at least in animal studies, it has “gone airborne” before. Theoretically, it’s an odds game. The more times the virus is copied — the better the odds are that the right mutation will occur. To be brutally blunt, every infected person is another incubator, providing more copies, and more chances. For this reason, and for self interest alone, the West ought to be shifting into high gear to help Africans contain this. The humanitarian reasons go without saying. But our compassion for the ghastly suffering spreading through the slums and cities of West Africa could easily save thousands, and possibly many millions of lives, theoretically including our own.
On the plus side, we are not defenceless. There are good news stories and promising avenues. Several vaccines are being developed. Most immediately, the blood of survivors contains antibodies that can help victims. The West has grown monoclonal copies of some antibodies (ie. ZMapp) but they only grow as fast as the tobacco plants they’ve been genetically modified to grow in. Ken Brantly, one of the early US survivors who was given ZMapp is now giving his blood to another afflicted American aid worker. In Africa, a black market has already sprung up trading the blood of survivors. It’s risky and it will spread other diseases, but it is probably a rational response given the dire odds. The WHO is organizing a better cleaner method. It’s one of the few times I think a government — dare I say, even a UN solution — is something to foster and hope for. Go big-government. Except, surprise, the free market beat the government, and now some in the WHO are trying to stamp out the “illicit trade”. (Do they even know the risk-benefit of these trades?) Shouldn’t they be advising consenting adults and carers on the safest way to do this, and the risks, and collecting statistics?
For roving ideas…
Bottom line: The BOM has added a page listing “Adjustments”. It’s two years late, inadequate and incomplete. Skeptics shouldn’t have had to ask for it in the first place, and we still don’t have the algorithms and codes, or rational answers to most questions. No one can replicate the mystery black box homogenisation methods of the BOM — and without replication, it isn’t science. There is still no explanation of why an excellent station like Rutherglen should change from cooling to warming, except for vague “statistics”, or why any station should be adjusted without documentary evidence, based on thermometers that might be 300 km away.
Lo and behold, the pressure from The Australian and independent analysts means the BOM has made a weak belated attempt to do what it has implied it always has done. When Michael Brown provided cover for the BOM he said the notion that scientists were hiding data was “pseudoscience”. The BOM, meanwhile, added a page called “Adjustments”, two years after launching “ACORN”, quietly admitting that the skeptics were right. They did not correct Brown’s baseless namecalling. Other apologists for their inexplicable anomalies, major adjustments or errors – like David Karoly — demand the skeptics publish in the peer reviewed literature before they will even consider their point of view, but neither Karoly nor the BOM can name the peer reviewed document, or any publication or link, with the full homogenization code. How can skeptics discuss a method in the peer review literature which is not publicly available? The BOM homogenization technique remains a black box method that cannot be replicated — only the secret guild of anointed BOM staff are privy to the details.
Let’s open that BOM black box: let’s have a replication of the homogenization process, open to public inspection, so it can be audited. So everyone can see where every homogenized number came from, back to the raw data and the adjustments. No public company could shield its finances from observation like this: they have to produce audited accounts every six months that show all money in the company bank account, all money owed, and all money owing. All of it.
And once we have replication, then we can have an informed discussion of the ramifications of the current homogenization process, and how it might be improved or made more realistic.
Is the BOM a science agency or a PR bureau?
On August 29 2014 the BOM said it had published everything:
BOM said its methods had been published in peer-reviewed scientific journals but did not say where or in what form.
Later on Sept 11, 2014, the BOM says they have finally complied with a recommendation made years ago:
A spokesman for BoM said “publication of this table meets the Bureau of Meteorology response to the recommendations of the Independent Peer Review Panel”.
So which is it? Either they were wrong before that the methods were published, or they are repeating information now and pretending it is new in the hope of getting the critics off their back. The answer is “both”. It was inadequate before. It’s still inadequate now.
The new “adjustments” page doesn’t resolve much at all. There are still blatant errors — The changes to long term trends in minima are not “neutral”, but increase the trend by nearly 50% (See Ken Stewart’s site here and the finished set here). The hottest day in Australia was almost certainly not in Albany in 1933 (which remains uncorrected at 51C). Many maximums have been adjusted and become lower than minimums. Those mistakes did not exist in the raw data. The homogenisation has created them, like the new discontinuity in Deniliquin.
The adjustments page is just a glorified rehash of the same old excuses
Effectively the bureau is saying “we need large mysterious transformations of data to make Australian trends look like international trends”. What serious climate scientist thinks Australia is supposed to get hotter, colder, wetter, drier, or cloudier with the exact same timing and patterns to the rest of the world? Even high schoolers know that when it rains on the East Coast with El Ninos, it’s not raining on the other side of the Pacific. Just because other homogenizations have produced the same trends by blending data to the point where it is unrecognisable does not make it “good” science.
Lots of international bankers were marketing the same overrated mortage bundles. Anyone want to buy subprime science — I have a collateralized trend for sale?
Three years ago the independent audit team, with Senator Cory Bernardi, asked for an ANAO audit of the BOM’s “High Quality” HQ data set. The BOM was not enthused. They dumped the HQ set that they had previously lauded and set up a new one called “ACORN”. We listed some of the errors in June 2012. Two years on, nothing much appears to have changed. They still haven’t released the algorithms used in the homogenization process. They are still using stations more than 100km away, some 600 km away, to “adjust” temperatures. The mystery black box adjustments are still producing inexplicable nonsense, and the BOM still can’t explain why — on individual stations like Rutherglen and Bourke — anyone should find their adjustments necessary and scientifically justified. There is no documentation showing Rutherglen has moved. But there is documentation suggesting perhaps Bourke’s deleted “hottest” day really might have been 125F in 1909.
The BOM’s active silence on the long hot records of the late 1880s and 1890s suggests they are more interested in promoting one message — “it’s warming” — rather than being custodians of the real and more complicated history of the Australian climate.
The BOM still hides the “warming” effect of their mysterious adjustment procedure
The official CAWCR Technical Report No. 04 claimed the adjustments were “balanced”:
“There is an approximate balance between positive and negative adjustments for maximum temperature but a weak tendency towards a predominance of negative adjustments (54% compared with 46% positive) for minimum temperature.”
Even in 2014, the BOM still maintains that the adjustments do not affect the national trends:
“And the bureau says an extensive study has found homogeneity adjustments have little impact on national trends and changes in temperature extremes.” — August 23, 2014
But a simple analysis shows this to be a misleading half-truth. The number of adjustments may be balanced, but Ken Stewart shows that the size of the warming adjustments is so much larger than the cooling adjustments that nationally the mimimum trend are warmed by nearly 50%. Given that skeptics pointed out the size of adjustments was larger two years ago, it would appear the Bureau is aware of the problem, but instead of justifying or fixing it, they carefully created ACORN so they could be seen to answer the critics while maintaining the same bias in the results. Seeming, not doing.
Where are the computer codes?
BOM’s 2011 independent panel called for the release of the computer codes:
“recommended a list of adjustments be made publicly available along with the adjusted temperature series including the rationale for each adjustment. It said the computer codes underpinning the national ACORNSAT data-set, including the algorithms and protocols used by BOM for data quality control, should be made publicly available.”
Graham Lloyd’s article in The Australian yesterday shows that the BOM is under pressure, but their lack of transparency continues, and this new page appears to be more like a public relations effort than a big advance scientifically.
What Australia needs is a full working replication of the BOM methods and techniques — only then does a true scientific peer review process begin. If the BOM is so sure it’s doing obvious world’s best practice, why won’t it release the full code? Unpacking and replicating this detailed procedure would take months of analysis. If the Australian government is serious about our climate, they need to fund a proper independent study instead of leaving it to volunteers to do on the weekend, and hoping that someone with the right combination of IT, statistical, climate, and scientific skills will find it entertaining and want to do it for free.
The Greens would surely support more funding for climate research and a better, more rigorous Australian climate database. To oppose independent replication of the BOM procedures is to admit that they prefer the BOM to be a PR agency, not a scientific group.
Bureau of Meteorology warms to transparency over adjusted records
THE Bureau of Meteorology has been forced to publish details of all changes made to historic temperature records as part of its homogenisation process to establish the nation’s climate change trend.
Publication of the reasons for all data adjustments was a key recommendation of the bureau’s independent peer review panel which approved the bureau’s ACORN SAT methodology.
BoM posted a new site on its ACORN SAT website on Monday, two weeks after being questioned by The Australian about the transparency of its homogenisation process.
Independent researchers had been calling for publication of BoM’s methodology for more than two years.
All my posts on the BOM show that there are still more questions than answers.
The page for ACORN-SAT data.
The page for the entire computer code… does not exist.
Once upon a time, Australian climate scientists discussed and published climate trends of the late 1800s. And lo, the long lost hot weather decades were apparent in many places in inland South Eastern Australia. While skeptics are accused of cherry picking data from Bourke, Rutherglen and Deniliquin, there are plenty of other examples. In the last post, the 1953 Argus story described hotter drier summers in Omeo, Bendigo, Hay, Bourke, Alice Springs, Echuca, Albury, and Cooma. Here is a Deacon et al peer reviewed graph of the long term trends at Hay, Narrabri, Bourke and Alice Springs.
Thanks to Chris Gillham for finding the Deacon paper of 1952. [On another point, I'll have a response up to the new BOM "adjustments" page later. In short, their data still has many inexplicable errors like where maxima are lower than minima, and they are still not providing all the details we need to replicate their data and homogenization methods. - Jo]
But just have a look at this graph. Degrees Fahrenheit of course. State of the art, 1952.
These cooling trends cover “only” a couple of million square kilometers of Australia:

Imagine, they even had barometric data from 1880 in small country towns of NSW.

The average maximum temperatures [of SE Australia] during the last 35 years were between two and four degrees (F) lower than the average for the previous 35 years. — CSIRO 1953
Once upon a time — before the Great Politicization of Climate Science — CSIRO was able to analyze trends from 1880 to 1910. In 1953 CSIRO scientists were making a case that large parts of Australia had been hotter in the 1880s and around the turn of last century. They are referring specifically to summer maximums, and presumably the increase in rainfall over the same period played a large role in preventing hot days from becoming hotter. Minimum and mean trends may have been quite different, but these older maximum records are surely relevant when news headlines are drafted today about hot summers and heatwaves.
So what happened to the widespread lost hot decades?
I have a lot more to say on the warm and the work of these scientists. For the moment, the full archived news story is entertaining in its own right. Thanks to Chris Gillham for this link and to Jennifer Marohasy. Graphs tomorrow : – )

MELBOURNE’S WEATHER IS CHANGING!

You won’t believe…
Research shows surprise global warming ‘hiatus’ could have been forecast
[The Guardian] Australian and US climate experts say with new ocean-based modelling tools, the early 2000s warming slowdown was foreseeable.
Australian and US researchers have shown that the slowdown in the rate of global warming in the early 2000s, known as a so-called “global warming hiatus”, could have been predicted if today’s tools for decade-by-decade climate forecasting had been available in the 1990s.
And I’ve got a model that would have predicted the 1987 stock market crash, the GFC, and the winner of the Melbourne Cup. What I would not have predicted is that lame excuses this transparent, would be made by people calling themselves scientists, Gerald Meehl, and repeated by people calling themselves journalists. (That’s you, Melissa Davey). Though I’m not surprised that research this weak had to be published by Nature. (Where else?)
Although global temperatures remain close to record highs, they have shown little warming trend over the past 15 years, a slowdown that earlier climate models had been largely unable to predict.
This has been used by climate change sceptics as evidence that climate change prediction models are flawed.
Imagine that, the stupid skeptics think that “climate change prediction models” ought to be able to predict climate change.
But climate scientistsTM are working with different and special models. These ones are able to travel back through time to make their “predictions” from after the event.

Back when CO2 levels were ideal, and there were 1 billion less cars than today, monsoons always happened in the same place, the rain was the same year after year, and there were no local extinctions of animals.
If we could only return to renewable slave power:
[ScienceDaily] The researchers identified five episodes over the past 6,000 years when dramatic changes occurred in Egypt’s mammalian community, three of which coincided with extreme environmental changes as the climate shifted to more arid conditions. These drying periods also coincided with upheaval in human societies, such as the collapse of the Old Kingdom around 4,000 years ago and the fall of the New Kingdom about 3,000 years ago.
“There were three large pulses of aridification as Egypt went from a wetter to a drier climate, starting with the end of the African Humid Period 5,500 years ago when the monsoons shifted to the south,” Yeakel said. “At the same time, human population densities were increasing, and competition for space along the Nile Valley would have had a large impact on animal populations.”
No climate models were harmed in the production of this paper.

The ABC Drum Pater Burdon asks: Is democracy hurting our climate change response?
Indeed! Burdon is impressed with Naomi Orsekes’ speculation that China will “weather” the climate change storm because it is an undemocratic (and glorious communist) state. This same country builds the equivalent of a new coal powered plant every 10 days, and suffers from smogifying pollution so crippling that up to 250,000 people may be dying of it. Let’s try that “centralized” government where peaceful activists and people who complain about corruption get jailed or risk torture. And who could forget the “success” of big-government in China last century — no other style of government has successfully killed as many people, ever.
Is it democracy that is blocking progress on climate change or the current limited version of it that pervades Western society? Peter D Burdon writes.
The third possibility is that democracy is working just fine, and the masses of “dumb” voters have it right. What if believers can’t convince the voters that their alarming-tax-plan can stop the storms because the case for a carbon-crisis is pathetically weak? Could it be that people don’t need a degree in the history of feminist art to see that climate scientists got it wrong, there is still snow, and the world is not like the simulations?
This is something Burton and the ABC fans simply can’t imagine:
“The strongest argument against democracy is a five minute discussion with the average voter.”
This glib remark supposedly from Winston Churchill encapsulates a scepticism that many people have about democracies and their ability to respond to a crisis. Democracy, according to this view, is an endless meeting that provides everyone (regardless of their expertise or ignorance) an equal say.
The real failure of democracy
The current failure of democracy is that Western nations are spending so much to solve a problem that most of their citizens don’t want their money spent on.
Badly designed polls with vague motherhood type questions can make it look like half the population wants to “do something”. But better polls show that most people don’t want to spend anything. In the UK 62% of people are skeptics. Globally, 63% don’t want their dollars spent on the environment…. The environment is low on the list of concerns, and only 3% of Americans name “environment” as the top issue. Worse for alarmists, climate change is low on the list of environmental issues — in Australia “climate change” ranked 7th out 8 of environmental concerns.
When big-government fails, the answer is more and bigger government
The inefficiency of democratic governance in responding to crisis is acknowledged in the wartime practice of increasing executive power and suspending debate and ordinary decision-making mechanisms.
Following this example, a number of climate advocates have begun considering the benefits of greater centralisation in decision-making to mitigate the devastating scenarios offered by climate scientists.
For example, in an interview about her new book The Collapse of Western Civilization, Naomi Oreskes argued: “If anyone will weather this storm it seems likely that it will be the Chinese.”
And so collective self reinforcing blindness makes it possible for Peter Burdon to suggest that the nation which produces more greenhouse emissions than any other nation, where democracy doesn’t exist, and where human rights are a real issue, might somehow be a nation we can look up to? A great leap forward indeed.
The largest moneyed interest stays invisible
Burton talks about the effect of “vested interests” on democracy, but completely misses the largest single vested interest by far.
Oh, the conspiracy of it all…

Ninemsn (major network news in Australia) held a small poll on it’s home page on Friday, asking Do you believe global warming is man-made?
The ratio stayed roughly the same from start to finish. (Here, early on, it was 44% skeptical).
Matty in Perth kept track of the tally, and while the poll seems to have disappeared off the home page (can anyone find an archive?) at last count it was 39,899 yes and 33,960 no which was 46% skeptic of a total of 73,859 votes.
Of course, these are unrepresentative, self selecting polls. It underestimates the number of skeptics. The latest CSIRO survey shows 53% of the Australian population don’t agree that “humans are causing climate change”. Nonetheless, we trust Nine news notices the large response of its own audience. There will be some major ratings wins out there for whichever commercial news service notices that almost everything they broadcast on climate change is a bore and a turn-off for half their audience.
And as far as the ABC goes, as I’ve said before, when it gives 50% of its climate budget and time to skeptical arguments we will know it is fulfilling its charter.

For otherwise homeless thoughts…
He’s the new President of the British Science Association (I bet they are loving this media coverage) and has decided to move on from the old technique of debating scientific points on their merits. It’s too slow (especially if you don’t have… evidence). Instead he’s going with retro-science — Do you believe, sinner? It’s so retro, it’s retro-the-renaissance.
The Daily Mail UK
Politicians who do not believe in climate change should be ‘crushed and buried’, according to the new president of the British Science Association.
How much belief is enough, I wonder, to avoid the crushing? If a politician believed in the greenhouse theory but not the catastrophe, is that half crushed, or do we skip the squishing and go straight for the burying?
Sir Paul Nurse, who starts his presidency next week, pledged to ‘take on’ the ‘serial offenders’ who he accused of cherry picking scientific facts to suit their arguments.
In an extraordinary outburst, Sir Paul accused those who refuse to accept scientific orthodoxy on global warming of ‘distorting’ the facts.
Sir Paul singled out GWPF — as “pretending to talk about science” — and he whipped them mercilessly with ad hominem fallacies, generic infringements, petty insults, and argument by association.
He chanted the liturgical sacrament:
“‘Today we have those who mix science up with ideology and politics, where opinion, rhetoric and tradition hold more sway than adherence to evidence and logical argument.”
Lo, behold, it’s a form of confessional projection. If Sir Paul “swayed some evidence” he wouldn’t need to preach adherence to his ideology with violent threats, baseless opinions, and logical errors.
Time to write letters to the British Science Association.
Amazing what they can discover with data from just the last 130 years. Hey but it must be right. It’s bootstrapped!
Finally, the study you’ve been waiting for. Now we can be absolutely certain — it’s practically proven beyond all doubt – your SUV changes the climate.
We just need to assume the climate models understand the climate and that there are no longer natural cycles at work AND that there are no effects from the sun from the solar wind, solar magnetic fields, or spectral changes. Easy. (Don’t look at the evidence, the pause or all the model failures.)
The new headline:
99.999% certainty humans are driving global warming: new study
It’s at The Conversation - -the government funded site where government funded scientists discuss their bestest ideas.
WARNING – Modern global temperatures (red) were homogenized with imaginary Vostok data for entertainment purposes only. See footnote*
Obviously being 95% certain is not enough. Desperate believers are upping the ante. I guess all those people who were not convinced by 95% certainty will now switch over, blown away by the last 4.999% certainty that was missing before. It’s the third decimal place that does it.
PS: There’s a vote going on at NineMSM. See the poll in the middle of the page – Do you believe?
*The graph contains satirical-risk. The blue line is Vostok. The red line is
Vodka, “the globe” with polar-exaggeration. Don’t compare them under any circumstances.
The list goes on, and there is more to come.
In Deniliquin NSW, the homogenisation has lifted both the maxima and minima trends — again converting cooling to warming.
Graham Lloyd continues to increase the pressure on the Australian Bureau of Meteorology. In answers to Lloyd the BOM could only defend their work with the extraordinary statement that while some trends at individual stations look anomalous, overall the results “showed a similar warming trend to that of other international climate organisations. ”
So they inadvertently admit that they expect Australian trends to look like trends in other parts of the world. Despite the fact that Australia is drier, flatter and surrounded on every edge by oceans, the Bureau would consider it a fail if our trends were different to others? We’re in the opposite hemisphere to many international climate organizations, which may or may not matter, but we’ll never find out if we are trying to fit our data to theirs. And El Nino’s and La Nina’s mean very different things to countries on opposite sides of the Pacific. We’re blurring the resolution from thousands of data-points. The raw data is blended not just on regional scales but thanks to mindsets, on international scales too. It’s Groupthink, or should we call that Climate Freud at work?

Bureau of Meteorology ‘adding mistakes’ with data modelling
Both Maxima and Minima trends have changed after BOM homogenization.
SOME of Australia’s long-term temperature records may contain faults introduced by the Bureau of Meteorology’s computer modelling, according to a widely published expert.
David Stockwell said a full audit of the BoM national data set was needed after the bureau confirmed that statistical tests, rather than direct evidence, were the “primary” justification for making changes.

People who have no cheap electricity burn wood or coal inside their homes to make dinner and stay warm. The smoke produces real pollution (as opposed to the fake kind which feeds plants). In India, some homes have pollution levels “three times higher than a typical London street”. Not surprisingly, living in smoke does not work out well for lungs and hearts. “Estimates suggest that household air pollution killed 3·5 to 4 million people in 2010. “
We can argue about the numbers and whether they are exaggerated, but there’s no doubt that millions of people would lead better lives if they had access to cheap electricity, which in practical terms means coal-fired power. In Niger, Africa, 17 million people use less electricity than Dubbo, NSW, a town of 40,000.
Where are the Greens? Children in poverty are suffering from lung damage now. The Greens priority is to spend billions to stop them dying in 2100 from seas rising at 1mm a year. How many people does expensive electricity kill? — Jo

Was January 3rd 1909 in Bourke one of Australia’s hottest days ever?
The historic records say “125F” — or 51.7C.
The BOM say it was an observer error.
Bourke and neighboring stations in NSW and QLD Australia
Blair Trewin wrote a paper looking at the extreme highs in 1997. The Bourke record was made on a Sunday and in that particular year there are no records on other Sundays. On the other hand, I wonder what station observer would not notice a day that was 125F and head in to work to see exactly how high it was. The number 125F was handwritten in and underlined. You’d think observers would know it was a special figure, and pay attention.
The town of Bourke got a Stephenson Screen only a few months beforehand in August 1908, so it had good modern equipment. But Trewin thinks the record is an observer error, and points out that it was a lot warmer in Bourke than in other surrounding towns like Thargomindah, Walgett, and Coonable, and by about 6.9C degrees, which is an unusual gap. During the rest of the month Bourke was “not exceptionally hot compared to other stations”. Fair point. But Jen Marohasy responds that “newspaper reports show the nearest station, Brewarrina, had recorded 123F (50.6C) on the same day (January 3, 1909).“ Official Brewarrina records don’t start until 1911.
For scale. Bourke and neighbors.
I can understand why there is some debate about this record, but I don’t understand how it’s scientifically accurate to issue press releases declaring that we know Australian temperature trends, or understand how our extremes have changed. The statement “hotter than any time since 1910″ might be technically accurate in a way, but is very misleading when it relies on guesses about which high numbers were accidents, and avoids any mention at all of the hot weather before 1910.
It is great to see Graham Lloyd is fearless in following the data and arguments.
The Australian “Heat off Bourke after Bureau of Meteorology revision”
THE removal of a longstanding temperature record at Bourke of 125 degrees Fahrenheit (51.7C) set in 1909 was the result of a critical 1997 paper that revised a string of records and brought Australia’s hottest recorded temperature into the second half of the 20th century.
Until the paper by Blair Trewin, who is now a leading climate scientist at the Bureau of Meteorology, Australia’s hottest recorded temperature was 53.1C at Cloncurry on January 16, 1889.

We’ve seen the remarkable change of the Rutherglen record as it got homogenized. This long running rural record that looks ideal apparently had “unrecorded” station moves found by thermometers miles away. Already we have found Bill Johnston who did some work at Rutherglen who confirmed that the station did not move. The mystery grows?
Since early 2012 Ken Stewart has been asking the BOM which neighbouring stations were used. Finally, after pressure from The Australian, the BOM has provided the 17 names, and Ken has graphed them.
Follow the chart below. Rutherglen temperatures start off in blue. The yellow line is the average of the 17 “neighbours” which are used to homogenize that blue line and transform it into the red one which somehow ends up being colder than its neighbours in 1952 and warmer than its neighbours in all the last 30 years.
See if you can figure it out?
Rutherglen starts off blue. Then the yellow line is used to homogenize that blue line into the red one.
Presumably the BOM technique would be a lot more complicated that what Ken has done, but clearly replicating that ACORN final trend is not going to be easy.
The 17 neighbouring places stretch from Beechworth in the foothills of the Victorian Alps, to Hillston on the flat plains of hot New South Wales. Hillston is about 370km by road from the wine growing district of Rutherglen. It’s 300km direct according to this estimate. Hey but maybe their climate trends are more similar than they appear…
Hillston is the top left red dot on the map below.

Blades being chopped for transport. | Global Cement Magazine
It’s the new alternative fuel — decommissioned turbines. There are 21,000 wind turbines in Germany alone at the moment. With 15,000 tons a year of old blades expected to be dumped by 2019, it’s a real problem to get rid of them. The EU says they can’t be dumped in landfill. Here’s the perfect solution. Chop them, shred them, then deliver the fibreglass reinforced plastic to the local cement plant. The resins hold 15MJ per kilo. “One tonne of resin saves 600 kg of coal at the cement plant!”
It’s a win-win all round. Residents get rid of the bird chopping towers, the cement plant gets energy, and the windmills may, possibly for the first time, save some CO2 for the Greens. What’s not to like?
Indeed this is recycling you can like. The raw materials in old blades can even be used in the cement too.
Wind Turbines make good alternative fuels for cement production.
