Carnarvon “world’s hottest place yesterday” is barely any hotter than it was in 1896

— (AAP) NZ Herald

By Jo Nova

In Carnarvon yesterday the Bureau tells us that the temperature was “a record” 49.9 degree day (almost 122 Fahrenheit). But in 1896 the Brickhouse Station just 15 kilometers north of Carnarvon hit 121 Fahrenheit in the shade, and there were reports of birds dying and other measurements “in the shade” that were as high as 125F. Somehow man-made emissions have been heating the planet for 128 years but the current freakishly hot days are about the same as the ones when no one in Australia owned a car and CO2 levels in the atmosphere were still under 300 ppm.

Lest we forget, there are hundreds of thermometer records from the pre-1908 era that are apparently worth nothing to the Australian Bureau of Meteorology. Climate change threatens all life on Earth, so you’d think climate scientists would be excited about the longest historical records they can find, but for some inexplicable reason they show little interest in the historical records from 1896 when a heatwave struck and 437 people died across Australia.

Temperatures hit 50C in the shade in many places in January 1896. In locations hundreds of kilometers apart, people were […]

The BOM predicted a hot dry summer right before the flooding rains came…

By Jo Nova

Australians are angry the BOM didn’t see the flooding rains coming

Worse, we’re betting the nation on the BOM’s ability to predict the climate.

The Bureau of Meteorology (BOM) tells Australians that record breaking extremes are getting worse because of our cars and our air-conditioners (that’s “The State of the Climate“). But when the BOM can’t predict record breaking rain a month in advance, or even the day before, we know the BOM doesn’t understand what drives the climate.

Somehow the BOM expect Australians to spend trillions and rearrange their economy based on their fifty year prophesies, but not to mind when “this summer” goes right off the rails.

Back in September the BOM issued its El Nino alert, and Australians were told it would be a hot and dry and to prepare for a summer of bushfires. Farmer sold their lambs, and adjusted harvest accordingly.

This was the BOM solemn prediction in late October, for the very next month of rainfall

Across most of Australia the odds were only 20-40% of getting average rain.

Instead this is what happened:


And in December most of the country was predicted to have a fifty […]

That’s a big climate surprise: Frost season growing longer across Australia (and for years!)

Image by Penny from Pixabay

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 […]

What if the airport radar was generating false record-high temperatures through random electrical noise?

By Jo Nova

Electronic sensors can pick up phantom electrical noise

In the last thirty years the Bureau has installed electronic thermometers all over the country. But unlike the old glass ones, the new sensitive equipment can not only pick up freak gusts of hot air, they can also pick up electrical interference. Theoretically, electronic thermometers could report phantom measurements induced by large electric fields, like perhaps by an airport radar as it sweeps through the electronics.

Indeed as Lance Pidgeon points out, the cable that runs from the platinum resistance probe runs out of the Stevenson screen, down the pole, under the ground and pops up at the electronic data-logger some 6 to 10 meters away. This makes for a nice long aerial ready to pick up “noise” and feed it into the data-logger. Those airport radars produce huge electric fields — all it takes is slight induction of a voltage difference across the 10m cable and voila… the data logger records a “warmer” second.

Here’s the small forgotten airport radar at Heathrow standing about 12 stories high. Imagine the power that puts out?

Electromagnetic interference could also be triggered by mobile phones or radio […]

Why is temperature data a national secret? BOM still hiding data

By Jo Nova

Think of the BOM as an advertising agency for big-government programs, and it all makes sense…

Apparently, after the stinging criticism about them, the Bureau of Meteorology is telling journalists and academics that “they publish all the data”. Jennifer Marohasy has been fielding calls and correcting journalists on air who are fooled by this claim. Clearly this isn’t true, or she wouldn’t have needed to spend three years on FOI applications just to get a tiny part of it, (and in the least helpful form possible , like 1,000 sheets of paper). The Bureau not only don’t publish this data, they actively work to hide it and fight FOI’s.

The BOM are not only hiding national temperature data, now they are trying to hide that they are hiding it too. There is some dynamite secret here. Why is it so important — perhaps because it shows that the BOM installed new thermometers that register artificially higher temperatures than the old glass thermometers do? Thousands of “hottest ever records” have been set by new electronic thermometers that might not have been set if we still used traditional thermometers.

If the Bureau can’t be bothered giving […]

Is Climate Change really caused by electronic thermometers? (The BOM don’t want Australians to see the data)

By Jo Nova Electronic thermometers may read up to 0.7 degrees higher than glass ones.

Sometime in the mid-1990s the Australian Bureau of Meteorology replaced many of their glass thermometers with electronic sensors. They claimed they were carefully verified to match the slow way the old glass thermometers worked — after all, we wouldn’t want to use gizmos that recorded new all-time *Hottest Ever Records* that were actually just one-second gusts of hot air, would we? Our newspapers would be full of meaningless headlines about how Climate Change made us hotter than ever in history, when really it was just a mistaken effect of a new type of thermometer. Imagine that disaster of public policy…

Of course this question is so easily solved. The BoM just needed to keep the two thermometers side by side in the same boxes and record all that data. Then they could release it, showing how well the electronic gadgets mimicked the glass thermometers, and Australians everywhere would feel confident that BoM was the sterling agency they thought it was. Instead Skeptics have been asking for comparison data for nine years and the BoM has refused, hedged, asked exorbitant fees, destroyed data and […]

Expert BoM excuses about a solar panel leaning on bushes near Sydney’s official thermometer

By Jo Nova

Two days in a row, this blog has been quoted in the Daily Telegraph.

Congratulations to Clarissa Bye for shining a torch on the BoM

Craig Kelly found the wandering solar panel leaning on a bush near Sydney’s official thermometer, and I wrote about what a strange spot that was to leave a solar panel. Then Clarissa Bye of the Daily Telegraph picked up the story and on Jan 25th asked the BoM why the panel was there. After a whole week of missed deadlines, with pleas for extra time, The Daily Telegraph gave up waiting and published the story Wednesday:

Questions raised over mystery solar panel at Sydney Observatory

Science blogger Jo Nova has also queried the solar panel’s location, describing the BOM as “lackadaisical” at best in maintaining weather sites. “The solar panel is exactly due south of the Stevenson screen where the thermometer is kept,” she said. “If, hypothetically, someone wanted to leave a reflective object pointed at the box at midday, that’d be the place to do it.”

““There’s only been one day above 30 degrees since February 21st last year in Sydney, and that was a day […]

Just like that: the suspicious solar panel disappears. The Bureau of Met experts at work?

By Jo Nova

Remember the nomadic solar panel that appeared a few meters due south of the Sydney Observatory thermometer at the same week as the city ended it’s coldest streak in 140 years? Well Craig Kelly, who took the original photos, went back and now its gone.

Today there is just grass and shrubs to reflect the midday sun towards the back of the thermometer box.

Photo by Craig Kelly 27th January 2023

As Craig Kelly said: “The fact that it’s disappeared shows that it was never installed – someone at the BOM just happened to grab a random solar panel and place it at such an unexplained position…”

So much for expert rigorous science accurate to a tenth of a degree.

Kelly explains that this site is nearly invisible: “The only way you can see it is by holding a camera above your head – it’s not visible to the eye – even if you were 6’6” and standing on your toes you can’t see over the fence – and the Observatory is closed to the public for some unknown reason.”

Perhaps the BOM just thought no one would notice, and “it’s for a good cause, […]

Jolly Odd what: Sydney Observatory record cold spell broken with help from AWOL solar panel?

By Jo Nova

Golly but, that’s a strange spot to leave a solar panel…

Sydney reached the longest cold streak for 140 years, and it looked like it might become the longest ever. But then a few days ago, after 331 days of cool weather, temperatures reached the magic 30.2C* at Observatory Hill Sydney ending the newsworthy cold run.

Back in 1883 Sydney had 339 days in-a-row where the thermometer didn’t make it up to 30C (86F). Since then, five million people arrived, along with the Cahill Expressway, skyscrapers, and 100,000 cars a day, but even that, apparently, wasn’t enough artificial urban warming to reach temperatures of 140 years ago.

But Craig Kelly (former MP) has some footage from that famous site and asks “What’s going on here?”

Climate change causes roaming solar panels?

That’s a strange spot to leave a panel… | CraigKelly

It’s even more suspicious when looked at from above. The solar panel position (marked in red) is exactly due south of the Stevenson screen where the thermometer is kept (marked with an arrow). If, hypothetically, someone wanted to leave a reflective object pointed at the box at midday, that’d be the place to do […]

The year without a summer? In 2022 Sydney didn’t even reach 32 degrees

By Jo Nova

For the first time in 163 years of records at Sydney Observatory the temperature didn’t even crack 32 degrees C (or 90F) for the whole year of 2022. Despite CO2 being at higher levels than ever, Sydney has never had temperatures that were so un-extreme.

The hottest day all year at this historic site was just 31.9 C. When researcher Chris Gillham first mentioned this, I assumed he must have meant “for the month of December”. I could not believe Sydney would go a whole year without a single hot day, but here it is. Gillham graphed the hottest day of the year at Sydney Observatory every year since 1859 and it really is unprecedented.

So far the total media attention on this point is one tweet by a weatherzone meteorologist and a paragraph in The Sydney Morning Herald. (h/t b.nice and RealClimateScience). Has the BoM even said a word? If it was the hottest year in 163 years, we’d know all about it. The BoM is an advertising agency for government policies.

And this is despite many […]

The Australian Climate is Fine — but the State of the CSIRO and the BOM is a Crisis

By Jo Nova

The latest State of the Climate Report is out to scare everyone with plucked esoteric records based on dubious datasets adjusted with secret algorithms.

The star of the report is the 1.5 degrees of Australian “hockeystick” graph of warming (below). The Herald Sun calls it “Scary”.

The biggest crimes of this report are what they don’t say. The CSIRO and BoM must know, but don’t mention, that satellites don’t show any warming in Australia in the last ten years at all. Satellites track across all seven million square kilometers of Australia, and are calibrated against thousands of weather balloons. The CSIRO and BoM prefer to use thermometers in carparks, near runways, or close to incinerators, then they magically adjust trends at some sites up by as much as 2 degrees (that’s the whole century-long trend right there?!)

They also don’t mention that scientists in Australia were reporting that Australia was cooling from the 1890s to 1952. (Deacon et al) The ghastly heat of 1896, the Federation Drought, and the 50C record temperatures all over Australia all go down the memory hole.

Big Scary Graph according to the Sun Herald. From the State of the […]

Third world Australian Met Bureau cuts back on weather balloons. Scientists say it’s “kind of horrific”.

Giles, Weather balloon

By Jo Nova

Things are far far worse at the Australian Bureau of Meteorology than even we realized.

“If you think your public forecasts have gotten worse, that’s because they have,” one meteorologist says.

While Australia is flooding and lives depend on forecasts, the management of our weather bureau is cutting back on meteorologists and on weather balloons, but they’re making sure they do frivolous exercises in rebranding with a new kindergarten logo and calls to be “The Bureau”, and not the BoM.

It’s hard to believe, but instead of releasing two weather balloons from each site every day like the rest of the modern world, the BoM has decided to cuts costs and reduce many regional sites to just one or even none each day. This is in breach of the World Meteorological Organisation (WMO) standards. Weather balloons are the prize “unrivaled” meteorological instrument. In roughly 900 places all over the world, weather balloons are launched twice a day, every day of the year. These radio back temperature, humidity and wind and pressure data as they rise up as high as 30 kilometers (20 miles) into the atmosphere.

The degradation of […]

Long lost forgotten rain bombs — the BoM yells “unprecedented” while ignoring 120 years of history

If Climate Change was a real threat, the Bureau of Meteorology might even look at their own historic records.

When Jennifer Marohasy and Chris Gillham did just that, they found that as bad as the current situation is, it’s happened before:

The wettest day in Lismore was in February 1954. The wettest year for Lismore was 1893. There was no increase in the intensity or frequency of extreme wet days at Lismore, or the towns around it.

Now if the BOM looks at this with a supercomputer, they might find an effect from CO2. But if the BOM just used a calendar, like I did, they might find the latest floods started the week after Hunga Tonga volcanic dust rolled across Australia. Maybe that matters?

No one needed a supercomputer to read a rain gauge in 1885, and we have excellent long data. Imagine how handy that might be if the BoM wanted to understand, say, Australian flood cycles? There are 137 years of rainfall records in Lismore from 1885 to now, but the BOM said we set a new record for Lismore based on Lismore airport where records started as long ago as… 2002.

The Bureau of Meteorology finds Australia is still getting colder a century later

Surprisingly, the World War I era temperatures are still changing. Mornings that seemed nippy at the time are now susceptible to frosts.

Someone should warn the farmers — except they’re all dead.

Thanks to Chris Gillham for independently and laboriously going through the new unannounced changes in another cycle of BOM’s hidden revamp of Australia’s history. ACORN 2.2 is the latest version of the Australian Climate Observation Reference Network of “the best” 112 weather stations across Australia.

Bureau of Meteorology ‘cools the past, warms present’

Graham Lloyd, The Australian

“The bureau has now remodelled the national temperature ­dataset three times in just nine years,” Dr Jennifer Marohasy said.

In the last five years the ACORN re-revisions by the BOM have discovered another quarter of a degree of warming that we didn’t know about from the last hundred years. It’s not clear why the BOM doesn’t want to tell the world how good they are at correcting thermometer records from 1913. It seems like a remarkable skill.

The minima just keep getting cooler

Chris Gillham plots the longest running stations from the ACORN 2.2 set against the old raw readings:

Magical seven year record wins the Hottest-ever Bingo of 2021

Why does “seven years” suddenly matter?

“The past 7 years have been the hottest on record

“by a clear margin,” scientists say”

Since when do we do climate analysis on seven year periods? — Since climate scientists get rewarded for scaring taxpayers and “seven” is this years lucky number.

2021 wasn’t THE hottest year so they have to come up with something

In climate “science” there are always a thousand combinations and permutations of climate records to pick from, so it’s a snap to find one that sings. If it wasn’t the hottest year in 2021, it might have been the hottest global summer, warmest winter, driest spring, or stormiest “on record”. And if temperatures stop rising, the hottest year record stretches elastically into the hottest 2-years, 3-years and 5 years-on-record.

Scientifically, the climate interval that matters most is whatever it has to be to stretch out and sing “Bingo” — “The Met Bureau needs more money.”

Naturally all Climate Bingo games are boosted by inexplicable adjustments, badly placed thermometers, shrinking thermometer screens, and the process of constantly rewriting history. If the incinerators near thermometers don’t do it, the homogenization will. They might be Australian […]

Magically correcting Australia’s thermometers from 1,500 kilometers away

The Australian Bureau of Meteorology uses “surrounding” thermometers to adjust for odd shifts in data (caused by things like long grass, cracked screens, or new equipment, some of which is not listed in the site information). The Bureau fishes among many possible sites to find those that happen to match up or , err “correlate” during a particular five year period. Sometimes these are not the nearest site, but ones… further away. So the BOM will ignore the nearby stations, and use further ones to adjust the record.

These correlations, like quantum entanglements, are mysterious and fleeting. A station can be used once in the last hundred years to “correct” another, but for all the other years it doesn’t correlate well — which begs the question of why it had these special telediagnostic powers for a short while, but somehow lost them? Or why a thermometer 300km away might show more accurate trends than one 50km away.

One of the most extreme examples was when Cobar in NSW was used to adjust the records at Alice Springs –almost 1500km away (h/t Bill Johnston). That adjustment was 0.6°C down in 1932 (due to a site move, we’re told). This potentially matters […]

Bureau of Met reads tea leaves and finds warming at Horn Island that no thermometer can see

Ken Stewart has been looking at the mysterious pattern of temperatures on Horn Island –– right at the top of Cape York Australia. It’s almost as far north as things get in Australia. There was no thermometer there before 1995, so the Bureau of Meteorology has rattled the nearest tea-leaves to find out how warm it was.

The towns listed on the map are its nearest neighbours. “Near”, in the Australian sense, meaning loosely within 500 kilometers.

Horn Island and it’s nearest neighbours

This, below, is the way 70 years of temperature dregs roll at all those sites.

This is what the Bureau of Meteorology sees (note the scale has changed on the temp axis). That’s two degrees of warming in far north Queensland.

So the average minimum temperature now looks half a degree cooler in 1960 than what your lying eyeballs suggest.

Ken goes into much more detail and deserves our thanks for bothering to try to unpack the mysterious merging of thermometer records in at the BoM department of Tasseomancy.

Hottest Day recorded and deleted in Australia was 51.7 C in Bourke in 1909

Do the BOM even care about Australia’s climate?

Craig Kelly in our National Archives yesterday

The hottest day ever recorded in Australia with modern official equipment was Jan 3rd, 1909 in Bourke where the temperature blistered at 51.7C (125F).

Yesterday the Honorable Craig Kelly MP trawled through historic archives looking for temperature records from a century ago to see if he could confirm that it really was 125F in Bourke that day, and whether it was almost that hot in Brewarrina too. Craig Kelly wants the record restored.

The site at Bourke is one of the oldest in Australia, starting in 1871. It’s also very influential because it was used to estimate the temperatures of vast remote areas around it. By 1909 there was already nearly 40 years of data at Bourke, and the Stevenson Screen had just been replaced so it was almost brand new. There was no airport tarmac either, so in 1909 the site was probably better than most modern sites are today. But the 1909 “hottest ever record” was deleted after an investigation in 1997 by Blair Trewin. It was written off as an error partly because it was recorded on a Sunday and […]

Announcing BomWatch: Auditing the fake warming created by site changes near the Great Barrier Reef

Fake Warming in Queensland: The BOM says the sites didn’t move, but photos show they did.

The warming at these four sites alongside the Great Barrier Reef is due to site changes, incompetence, poor record keeping and “adjustments”. Map: Terrametrics, Map data Google 2020

All along the coast near the Great Barrier Reef, the BOM has claimed temperatures have warmed in the last 50 years, and they’ve calculated it to a tenth of a degree. To get that kind of accuracy the thermometers need to be carefully placed, and the BOM needs to know exactly where they were, but they don’t.

The BOM keeps long pages of site descriptions and exact dates of moves and equipment changes, but historic photos show the records are wrong. The BOM will solemnly swear a site was in the same place for decades but photographs and archives show the sites were often moved as developments sprang up around them. The BOM didn’t keep the records and didn’t bother to check. If the thermometer moved to a warmer location or it warmed because they replaced the standard 230-litre Stevenson screen with a 60-litre toy one, or no longer cleaned it […]

ACORN adjustments robbed Marble Bar of its legendary world record. Death Valley now longest hottest place

UPDATE: The Hon. Craig Kelly MP was so appalled by this story he has taken this to the Australian Parliament already where The Labor Party was so afraid they interrupted his allocated 15 minute speech just to stop him finishing. They even called a formal Division which means the bell is rung and all the missing MPs have to return to the Chamber to vote. See that on Kelly’s Facebook page. Who cares about our climate and who covers up for incompetent bureaucrats?!

For generations it was a Guinness Book of Records type thing. Now it’s gone. In 1924 Marble Bar set a world record of the most consecutive days of 100 °F (37.8 °C) or above, during an incredible period of 160 days starting in 1923. It was legend — but thanks to the genius homogenized adjustments, we now find out all along it was wrong. It’s another ACORN triumph, rewriting history, extinguishing the hot days of days long gone. The experts at the Australian Bureau of Meteorology (BoM) have reanalyzed the temperatures from 4000 km away and nine decades in the future and apparently it wasn’t that hot.

Chris Gillham wonders how the bureau figured out the Marble […]
