Port Hedland: one man with a keen interest knows more about this site than the Bureau of Met does

If the planet was at stake you’d think the BOM would be doing this research, not unpaid volunteers.

Bill Johnston has shown again, that the BOM is apparently unaware and, perhaps most damningly, not even interested in most of the things that happened to their official thermometer sites.

Port Hedland is supposedly “one of the best” researched sites in Australia — so it is a certified ACORN site (one of the 112). The trends matter, and being remote, it influences a large area. But one man with dedication and no funding at all can find key historical maps and photos that the BOM, with its million dollar-a-day budget, cannot. Instead of doing this hard work the BOM uses the magical homogenization process “to fix” up all the anomalies by hunting for data in sites hundreds of kilometers away that can be used to adjust the records at Port Hedland. This is the secret process that even the BOM admits it cannot describe in full to anyone outside the BOM. As Johnston says, it’s a process so bad it “should be abandoned”. There is no saving the error correction that starts with bad data, missing documents, and barely any historical research […]

Australia: 2019 was not the hottest summer say satellites — it was just as hot in 1991

All that global warming and nothing to show for it?

Headlines rang out telling Australians that last summer was the hottest ever. But, according to the UAH satellite series, the hottest — just barely — was in 1991, when CO2 was a wonderful, safe 356 ppm. Since then, humans have emitted more than half — fully 58% — of all the emissions we have ever emitted since we crawled out of those dank caves. CO2 levels are almost 50 ppm higher now, and temperatures are almost as high.*

Wonder if this summer will get close to the summer of 1991 (and we wonder if Victoria will keep the lights on).

The UAH data comes from NASA satellites, which cover all the Australian land mass every day and night.

The BOM (and NASA) prefers to use Australian ground data which is based on sparse thermometers that keep changing sites and equipment, are located near airport tarmacs, buildings, and cars. When readings are too cold, the BOM sometimes deletes them. Temperatures from thermometers hundreds of kilometers apart are magically homogenized and “corrected” through a secret computer process and two thirds of our warming comes from those adjustments, not from CO2 […]

Who knew? The Australian Bureau of Met just made last summer hotter, and history colder (again)

The cheapest way to prevent man-made global warming is stop the BOM altering the data

First the BoM had “high quality” data. Then, with fanfare, after we asked for an audit they had the miracle of ACORN circa 2011. Then early this year ACORN 2.0 was quietly birthed with major adjustments as expert data became “more expert” but the BOM strangely didn’t want to mention that what was so good is now even better (apparently). The unofficial BOM audit team — especially Bob Fernley-Jones and Chris Gillham — have unearthed just how large the latest rewrite of history is. These men are truly independent, they have no funding, and nothing to gain either way. Please thank them for their unpaid dedication.

In this brazen latest round, even the summer of 2018 just got warmer. After all the headlines, after it was measured on supposedly modern first class equipment, even data just 18 months old is being re-fiddled. The temperatures read out on the news in January 2018? Nevermind what they said then. Those hottest ever records then were even hotter than the BoM thought, thanks to amazing new discoveries that the BOM doesn’t think are important enough to issue as […]

Maitland SA: Another expert thermometer site — and with incinerator “forcing”

Some days in Maitland are hotter than others.

The very non-compliant Maitland, SA, thermometer site #022008 | Imagery ©2019 Google, Oct 2014.

Thanks to Ken Stewart, the tour through the Great sites of the Australian Bureau of Meteorology continues.

Once again, the experts have carefully graphed, diagrammed, checked and ignored all the things that shouldn’t be within 30 meters of a thermometer. See Maitland Site Info. That fence is described as “Galvanised iron”. The ground is bitumen. The incinerator is labeled “incinerator”. And there are two tanks just out of view to the right, not to mention the tin sheds, trees, buildings and wind breaks.

In 1967 the site only had two tin sheds within a 30 meter radius, which was still not compliant, but vastly cooler than present. The incinerator is about 6 or 7 meters from the Stevenson Screen, and only appears on the maps in 2014.

As Ken says “the site is a heat sink”. It’s not an official “ACORN” star site, but records here get mentions in the media. Worse, Maitland is one of the sites used to adjust official ACORN data in Adelaide, Cape Borda, Ceduna, Kyancutta, Port Lincoln, and Snowtown.

Mt Barker — How not to measure the temperature

Thanks to Bill in Oz who sent in this photo of the Mt Barker site in South Australia.

Ken Stewart at Ken’s Kingdom writes: The Wacky World of Weather Stations: No. 1- Mount Barker

Photo: Bill in Oz.

Count the ways this site breaches the Bureau of Meteorology own rules:

Ken Stewart finds the relevant BoM guidelines. Clearly this site is on a slope, too close to buildings, too close to tall foliage, too close to heat sinks, it should not be artificially watered, or near asphalt. It should have a 30 meter buffer zone, and not be shielded from the sun, rain or wind. BillinOz points out that it is totally screened from the southerly cold winds, and the cold air will be drained from the spot down the slope.

How much do the Bureau of Meteorology care about climate change? — About 1m out of 30m or 3% of their advertised “care” factor. That’s a a 97% Junk-Science rate. The future of life on Earth is supposedly at stake and the “experts” can’t even be bothered accurately measuring the climate change they tell us we need to pay billions of dollars to solve.

Earliest recorded snow event in Western Australian history

Remember when climate modelers told us fossil fuels cause longer snow seasons?

No neither do I.

Albany, snowboarding, earliest snow, WA, 2019. | ABC Facebook

It is the earliest recorded snow event in a calendar year in the state’s history. Statistically, we can tell how anomalous this is by the behaviour of the local wildlife – seen snowboarding in shorts on the driveway in Albany. (Even going across the road). It’s possible this is the longest snowboard ride in the state’s history too. Though technically it is hail-boarding.

See snowboarding in Albany Western Australia

For foreign readers, WA (Western Aust) doesn’t have a snow season. Last regular snow was probably circa 20,000BC.

The ABC reports:

BOM forecaster Matt Boterhoven said snow was an extremely rare occurrence in April.

“It’s exceptional. We’ve only recorded once, in the last 100 years, snow as early as this on top of the Stirling Ranges,” he said.

“It’s related to a very strong cold air mass moving over the south-west of the state, so when conditions get below freezing and there’s precipitation, snow can form on top of Stirling Ranges.”

Mr Boterhoven predicted further […]

History keeps getting colder — ACORN2 raises Australia’s warming rate by over 20%

More warming adjustments from ACORN2

Once again we find that the oldest thermometers were apparently reading artificially high even though many were newish in 1910 and placed in approved Stevenson screens.) This is also despite the additional urban warming effect of a population that grew 400% since then. What are the odds?!

Fortunately, gifted craftsmen, sorry scientists have uncovered the true readings from the old biased thermometers which they explain carefully in a 67 page impenetrable document.

Chris Gillham has soldiered through the new “ACORN 2” adjustments that the Australian Bureau of Meteorology has o-so-quietly released and Australians are just waking up to find that our coldest mornings back in 1910 were even colder than anyone realized at the time. Graham Lloyd is reporting in The Australian how the second rewrite in six years increases the warming by 23% . (Where was the ABC announcement?)

The ACORN series of the Bureau of Meteorology includes 112 stations. Their report lists the warming trends per decade in Table 9. I converted that into the total warming since 1910 and graphed that below.

About one third of the warming of our mean temperature is due to man-made adjustments

Climate change is real because we are snowflake couch potatoes, addicted to netflix and airconditioners

Welcome to the DroneAge, where people act like robots and share dumb ideas at light speed! Episode #601: Climate change makes you lonely and fat.

Feeling friendless, floppy and like a loser? It’s not your fault. Blame a coal plant. Blame Exxon. Blame anyone but yourself. It’s your bad luck to be born into the most bountiful, benevolent era in human history. Damn!

Lonely, unfit and hooked on air-conditioning – is this the summer of the future?

Nicole Hasham, Sydney Morning Herald, uses new unorthodox indicators of “climate change”. Wait for it… test cricket attendance? It’s a smorgasbord of nonsense:

In Perth, cricket fans avoided an historic Test fixture amid predictions of 38-degree days. Sun melted a coastal highway filled with holidaymakers in northern NSW. Victoria’s coal generators shut down. Tasmania burned. And rotting fish corpses lining the Darling River at Menindee forced anglers to seriously rethink their plans.

Are we kidding? Thirty-eight degrees is just a summer’s day in Perth. It’s something that happens 19 years out of 20. As for coal generators shutting down: we’ve spent 20 years trying to drive them out of business to stop climate change, and now, if they don’t work, that […]

Forgotten history: 50 degrees everywhere, right across Australia in the 1800s

Don’t believe your lying eyes — Australian newspaper archives are full of temperatures recorded higher than 121 in the shade which is 50C. All of these temperatures in the map below are found in historic newspaper archives. Measurements done after 1910 are even done with official Stevenson screens, yet the BOM “throws them away”. It’s true that ones done in the 1800s are often recorded on non-standard equipment, or are just literally “in the shade” under cover. So some of these, perhaps many, are one or two degrees too high. But even if we take two degrees off, how scary is global warming when Australia knew many days of 48C and 49C and some at 50C 120 years ago? The BOM — supposedly so concerned about the State of Our Climate — show little interest in talking about our history or in analyzing it, or even mentioning it.

And modern temperatures are recorded on electronic equipment, sometimes in areas affected by urban heat islands (concrete and cars).

Forget Marble Bar, Oodnadatta, doesn’t the BOM know the hottest day ever was in Albany?

It’s summer, so the BoM and ABC can’t help themselves.

Albany, Hottest Town in Australia

Last week Marble Bar “hit an all time record”. This week, it’s Alice Springs. But the Australian BOM still haven’t used their own fabulous World Class ACORN Temperature data to find the hottest day ever in Australia. They’re still telling people it was in Oodnadatta, on Jan 2nd in 1960, but even dumb deniers know that according to ACORN temperatures hit 51.2C in Albany in far south WA in 1933.

[Marble Bar Dec 28th, 2018] The high temperature occurred at 12:39 pm local time. At that stage, it appeared Marble Bar could crack 50 for the first time — and perhaps even threaten the all-time Australian record of 50.7 in Oodnadatta, South Australia.

Chris Gillham pointed this out the strange anomaly of the cool coastal town that was hotter than a million square kilometers of desert, but four years later the BOM still haven’t resolved the situation. The 51.2C temperature is still there in the data, but the Top Ten Highest Temperature Records remain exactly the same. Is Albany, or is it not, the true record holder? Or is it that the […]
