The Australian Bureau of Meteorology have been struck by the most incredible bad luck. The fickle thermometers of Australia have been ruining climate records for 150 years, and the BOM have done a masterful job of recreating our “correct” climate trends, despite the data. Bob Fernley-Jones decided to help show the world how clever the BOM are. (Call them the Bureau of Magic).
Firstly there were the Horoscope-thermometers — which need adjustments that are different for each calendar month of the year — up in December, down in January, up in February… These thermometers flip on Jan 1 each year from reading nearly 1°C too warm all of December, to being more than 1°C too cold for all of January . Then come February 1, they flip again. Somehow the BOM managed to unravel this bizarre pattern (cue X-files music) and figure out exactly what anti-horoscope-adjustments to use (and they were different in every city). Modestly the BOM did not explain to the public how clever their adjustments were; despite their $300m budget, it took volunteer Bob Fernley-Jones to reverse out the Special Horoscope Cure, and find the square wave algorithm that repaired our damaged climate records. Lucky for the […]
Two out of three Australians live in our capital cities where the longest and best resourced temperature records would be found. These are the places where the weather reports matter to the most people on a daily basis — and where headlines about records and trends will be widely discussed. But these are also the sites which have been affected by the growth of concrete and skyscrapers, and potentially have the largest urban heat island (UHI) effect, so might need the largest adjustments.
Bob Fernley-Jones has been going through the BOM records for six of Australia’s state capitals, looking at the original raw data (at least, as is recorded in the BOM’s climate data online, called CDO). Bob compares the new “corrected” dataset called ACORN for these locations — that’s the all new marvelous adjusted data. He finds many step changes that can’t be explained by known site moves or the UHI effect. Many step changes occur in either minima or maxima, but not in both at the same time, which is also odd. As we already know, the adjustments usually cool the past — especially the minima (see all the blue lines on graphs below […]
Have you wondered what the global raw rural data tells us?
What did those thermometers say before the adjustments, smoothing, selection, and averaging?
This just might be the first time anyone has publicly compared the global raw data to published adjusted data sets in this way.
Frank Lansner has been dedicated in the extreme, and has developed a comprehensive Rural Unadjusted Temperature Index, or RUTI. One of the most interesting points to come out of this extensive work is the striking difference between coastal stations and inland stations. Frank kept noticing that the trend of the inland stations was markedly different from coastal stations and island stations.
Fig1. Red-Blue lines mark regions where there was a different coastal to inland trend. In green areas the two trends were similar.
What he finds is perhaps not so unusual: The coastal areas are heavily influenced by the sea surface temperature. Inland stations record larger rises and falls in temperature, which is hardly surprising. But, the implications are potentially large. When records from some stations are smoothed over vast distances (as in 1200 km smoothing), results can be heavily skewed by allowing coastal trends to be smoothed across inland areas. What Lansner […]
What would you say if you knew our high quality temperature record included sites with 100 year long “records” which were based on just 12 years of data and some undisclosed method was used to construct 90% of the graph?
Wow? I mean, Wow?! Why are these sites with such little actual data being included in a series called “high quality”?
Presumably the “adjusted” trends were recreated (in a sense) by homogenizing data from nearby stations, but why not use just the stations with long records in the first place? Out in the vast outback there are long distances between stations, and while a “splice” might overlap for ten years, who knows whether the dramatic PDO oscillations don’t shift weather patterns during their 30 year cycle and mean that any ten year period is not indicative of the longer time frame.
BOM compensate for the Urban Heat Island effect by making adjustments that essentially result in almost no change in the trend. They remove the “urban” stations, but UHI affects even small populations, and Andrew Barnham speculates that the largest changes in the UHI effect may occur in these smaller rural locations that are still included.
Andrew […]
Ken Stewart has been hard at work again, this time analyzing the Australian urban records. While he expected that the cities and towns would show a larger rise than records in the country due to the Urban Heat Island Effect, what he found was that the raw records showed only a 0.4 degree rise, less than the rural records which went from a raw 0.6 to an adjusted 0.85 (a rise of 40%). What shocked him about the urban records were the adjustments… making the trend a full 70% warmer.
The largest adjustments to the raw records are cooling ones in the middle of last century. So 50 years after the measurements were recorded, officials realized they were artificially too high? Hopefully someone who knows can explain why so many thermometers were overestimating temperatures in the first half of the 1900’s.
50 years later?
The raw Australian urban temperature records are in blue. The adjusted records in red. Note that temperatures in the middle of last century appear to be adjusted downwards. These are the annual average recordings for all 34 sites.
Remember Dr David Jones, Head of Climate Monitoring […]
This is yet another example of things that don’t add up in the world of GISS temperatures in Australia. Previously, we’ve discussed Gladstone and Darwin.
Ken Stewart has been doing some homework, and you can see all the graphs on his blog. Essentially, the Bureau of Met in Australia provides data for Mt. Isa that shows a warming trend of about 0.5 degrees of warming over a century. GISS takes this, adjusts it carefully to “homogenize urban data with rural data”, and gets an answer of 1.1 degrees. (Ironically among other things, “homogenisation” is supposed to compensate for the Urban Heat Island Effect, which would artificially inflate the trend in urban centers.)
To give you an idea of scale, the nearest station is at Cloncurry, 106km east (where a flat trend of 0.05 or so appears in the graph). But, there are other trends that are warmer in other stations. Averaging the five nearest rural stations gives about 0.6 degrees; averaging the nearest ten stations gives between 0.6 and 0.88 degrees.

By Jo Nova Climate experts wrong on Australian frosts, and media say nothing
The IPCC experts were sure would be less frosts in Australia, but buried in a government funded ABC weather report was the virtually unknown admission that the frost season is actually growing across southern Australia, not shrinking. And in some places by an astonishing 40 extra days a year. What’s more, the researchers have known about this long term trend for years but didn’t think to mention it, and the ABC didn’t have a problem with that either. (It’s not like farmers need to know these things?)
When asked for an explanation for the increase in frosts, the ANU climate expert said “I think this is one of those climate surprises,” as if the IPCC unexpectedly won a game of Bingo, instead of getting a core weather trend 100% wrong.
We note the ABC feigned journalism to cover up for the Bureau of Meteorology and IPCC failures. Where were the headlines: “Climate Change causes more frosts, not less”, or “IPCC models dangerously misleading on frosts?” Did any Australian farmers and investors buy up properties and plant the wrong crops […]
In the Victorian Supreme Court a judge has just ordered that the Bald Hills Wind farm must turn off at night time. After seven years of pain and suffering, two households living nearby will finally get night time relief and some payments of $92,000 and $168,000.
“The wind farm noise has been a common law nuisance at both properties.”

This could change everything. These industrial plants close to homes just became even less profitable because they can’t operate at night. They also need to pay damages to people affected by the noise, and do more maintenance to reduce noise — like repairing gear boxes more often, and they may have to pay to make changes at homes nearby to ameliorate the nuisance, or pay compensation. Many properties near the towers have abandoned plans to build new houses there.
What stands out in this ruling is how entirely inadequate were any of the attempts by the government that approved the wind plants, or the companies that profited from them, to measure and assess the noise, and to respond to complaints. Despite tens of thousands […]
All good environmentalists detest renewables and are appalled at the money wasted on the industrial renewables corporations.
All the rest are unwitting marketing agents who provide free advertising for banks and multinational conglomerate profits. In the process they hurt the poor and scorch the Earth.
In short: The world spent $3.6 trillion dollars over eight years, mostly trying to change the weather. Only a pitiful 5% of this was spent trying to adapt to the inevitable bad weather which is coming one way or another. Both solar and wind power are perversely useless at reducing CO2, which is their only reason for existing in large otherwise efficient grids. Wind farms raise the temperature of the local area around them which causes more CO2 to be released from the soil. Solar and wind farms waste 100 times the wilderness land area compared to fossil fuels, and need ten times as many minerals mined from the earth. Biomass razes forests, but protects underground coal deposits.
The role of large wind and solar power in national grids is to produce redundant surges of electricity at random or low-need times. They are surplus infrastructure designed in a religious quest to generate nicer weather. […]
In the largest city in a country with 300 years of coal left, yesterday the government asked a few million people to pull down the blinds on a midsummers day, to turn off the pool pumps, and not run the dishwasher from 4 – 8pm if they could avoid it. It was 42 degrees C.
Remember the good old days when the nation could afford to run the air con? Here in metropolis Australia, some days it’s better to bunker down in a few dark rooms with the air con at survival mode.
Welcome to Renewable World. What’s wrong with all those solar panels? Between dust storms and bushfires and the hail in Canberra, possibly they are covered in dust or soot, or perhaps, holes.
Imagine how much productive brain power is being consumed. The whole nation (almost) is becoming involved in management of the hypercomplex random generation network. As well as all those poles and wires and control rooms, we now need radio and twitter to send messages to the serfs to open and close windows, change their work schedules, or run out and click the pool pump off.

Tuesday was Australia’s hottest day on record sayth the Bureau of Meteorology.
And perhaps it was. But look at the temperatures reported in newspapers across the country during the month of January in 1896 when people were going mad with axes, dropping dead in coaches and railway stations and birds were falling lifeless from the trees? Emergency trains were ferrying people from the country to the mountains. Panic stricken people fled the outback on special trains and the death toll was in the hundreds.
Fifty years later scientists would publish papers talking about how Australian summers had cooled since then.
How does the BOM know for sure that it was not hotter on any one of these days? Perhaps they don’t. Wouldn’t it be more honest of the BOM to mention that? It’s not like billions of dollars depends upon it…
Seems the only time the ABC or BOM suddenly discover our historic weather records is when we get unseasonal snow or freezing cold.

With Alarmism off the dial, it’s nice to see some pushback coming from the near end of the science-scare. If journalists had asked questions like this back in 1988, it would have been all over by 1989.
Why Climate Alarmism Hurts Us All Michael Shellenberger, Forbes, does some research on the wilder climate claims. What a novel experiment! He gets answers (at least for now) by taking the line, as he says in his twitter account, “Climate change is real but there’s NO SCIENCE for apocalyptic claims”. So he’s a believer that is concerned about the needless rising anxiety and panic.
When the media says “billions will die” Shellenberger wanted to know why. He just pulled on that string and it all unravelled…
It takes a layers of incompetence to wind up an atmospheric spectral change into Death To Billions. Mass delusion and catastrophic hyperbole just doesn’t come from nowhere — it’s starts with incompetent scientists who never ask each other hard questions, not even in the tea rooms. They tell journalists ambiguously phrased, cherry picked lines which are then amped up by the media, who also ask no hard questions and go on to misquote and exaggerate. By then […]

The biggest changes in temperature (“divergence” in dark red brown Fig 6) occurred where the most people lived (blue dots). In the 60 years to 2010 China was reported to have warmed by 0.79 ± 0.10 °C. However Scafetta et al calculate at most, China could have experienced a real warming of only 0.46 ± 0.13 °C.
Somehow the combined might and supercomputers at NOAA, NASA, Hadley and the Bureau of Met experts all missed this.
It’s another third of a degree gone from the Glorious CO2 Narrative. Just like that.

Tim Flannery, 2004, The West Australian.
Flannery will be on Q&A tonight (bet you can’t wait, copy your questions and tweets below please!). Let’s check the exact wording of his original 2004 prediction that Perth would become a ghost town. It tells us something, not just about Flannery and a messiah complex (he really does talk of himself as an old testament prophet), but about journalism. Back then journalists interviewed critics too. Flannery was even called “alarmist” in 2004.
The original story had the calm headline: “Perth Will Die, says Top Scientist”. That article has gone beyond the space time continuum, but thankfully, it was preserved by the Wayback Machine.
Perth will become a ghost city within decades as rising global temperatures turn the Wheatbelt into a desert and drive species to the brink of extinction, a leading Australian scientist warns.
–Carmelo Amalfi, The West Australian
Perth in 2018, is wet, cool and productive and 30% larger:
Dams are at their equal highest level at the end of summer since 2002, and Perth has 67 billion litres more than any year of the last seven. The desert seems to be shrinking, arid regions […]
It’s another month of BOM Bingo. The ABC and BOM are trumpeting a “hottest” ever headline yet again, and Warwick Hughes is onto them already.
Conveniently the ABC forgets to mention that March Maximum Temps have been hotter before many times and with a pattern that has nothing to do with CO2. How many in the ABC audience would know that?
March temperatures sets record as hottest ever, Bureau of Meteorology says
“You could be forgiven for not noticing the end of summer — March was a hot one.” says Sara Phillips. But actually, if you are human, you could be forgiven for thinking this was just another hot March like so many before. For SE Australia where most humans live, the hottest March, and wildly so, was in 1940. Across the whole of Australia these kinds of maximum temperatures in March have been occurring for decades and 1986 was much much hotter. See the BOM graph below.
Hands up who can spot the horrid effect of CO2 in this graph?
Stick with the logic. Must be CO2 that caused the cold spike in 2011 (and 1967, 1942 and 1913). This is witchcraft.
You could be forgiven […]
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 […]
The ambit claims know no bounds. Who else would ask for $89,000,000,000,000? If the evil “more developed” nations pay for their carbon sins, the bill for those 1.3 billion people works out at $70,000 per person by 2030 (babies included).* When the target is 89,000 billion dollars, anything the Global Saviours get, can be painted as “not enough”. (It’s never enough). A trillion in funds is a “tiny”, “insufficient” amount that is “barely adequate”. Compliant journalists will print those headlines. The crowd will pay the money and feel guilty they are not paying more.
Speaking of the loot, the world’s GDP is currently $70 trillion, so asking for $89 trillion is a claim on 8% of all the money turned over in the world economy for a decade and a half. Handsome!
There is a grand array of climate junkets for Global Worriers this year. A gala of red-carpet events culminating in Paris, from November 30 to December 11. The wheeling and dealing is on right now, months ahead — and though they talk about the importance of Paris, I expect that Paris is mostly the cabaret show (like UNFCCC event in Bali that I went to), and it’s the […]
UPDATE: *Chris has been over the entire dataset again, and makes a correction that adjustments account for 30-40% of the rise. A bit less than half. Headline updated. See his site for the newer stats. March 9, 2015
Adjustments that cool historic temperatures have almost doubled Australia’s rate of warming.
CSIR published “Meteorological Data” 1855 – 1931
There was a time back in 1933 when the CSIRO was called CSIR and meteorologists figured that with 74 years of weather data on Australia, they really ought to publish a serious document collating all the monthly averages at hundreds of weather stations around Australia. Little did they know that years later, despite their best efforts, much of the same data would be forgotten and unused or would be adjusted, decades after the fact, and sometimes by as much as one or two degrees. Twenty years later The Commonwealth Bureau of Census and Statistics would publish an Official Year Book of Australia which included the mean temperature readings from 1911 to 1940 at 44 locations.
Chris Gillham has spent months poring over both these historic datasets, as well as the BoM’s Climate Data Online (CDO) which has the recent temperatures […]
