Albany robbed of its coldest ever April day, BOM adjusts temp up 15 degrees C?!

Friday April 19th set more records than anyone realized. Not only was it the earliest recorded snowfall at Bluff Knoll and WA, but it was also the coldest ever April day in Albany and many other towns in south-west Western Australia. It may also be the largest single day temperature mystery I’ve ever seen in the official “raw” data.

Days like the 19th are extremely unusual in Western Australia — it’s a state that often doesn’t get any snow all year and when it does, the length of the entire snow season is measured in hours. So you might think the million-dollar-a-day Bureau of Meteorology would be paying extra attention. Instead it appears they have lost that day’s data in Albany, despite having two thermometers there to record it. One station is in the city itself and there’s an official “expert” ACORN station at the airport about 10km away.

Luckily Chris Gillham, unpaid volunteer, was watching the live half hour observations roll in at and saw that thermometers at the airport recorded a maximum of only 10.4°C at 11am that day, which he remarks is the lowest April maximum the BOM has ever recorded there. Strangely, the 10.4°C seems to […]

Australia’s new hottest day just “discovered”, not Albany or Oodnadatta, but Carnarvon (51 degrees in 1953!)

Who knew? With intrepid dedication the Australian BoM has uncovered our hottest ever day, buried under erroneous calculations, hidden from view in High Quality expert data sets that were World Class til they weren’t. Strangely the BOM hasn’t issued a press release, even though their supercomputer-marketing team put out a Hottest Ever January media release within hours of January ending. It appears the BOM hasn’t even issued a press release to tell the world they’ve finished the third complete reanalysis of Australian temperature history.

Luckily for the BOM, which may have run out of bytes or letters of the alphabet, volunteers like Chris Gillham of the unofficial BoM audit team noticed that the BoM ACORN dataset has become ACORN2. So we’d like to tell the world. Once again, the genius at the BOM is able to retrospectively compensate for all the flawed sites and thermometers that kept reading too high. Incredibly, no one noticed for a hundred years.

As we launch ACORN2 let’s remember how proud the BOM were of ACORN1. This is from them back in 2017:

Pied Piper 2018: Australian students skip school for mass protest

By David Evans

The BBC in Sydney reports:

Thousands of Australian school students have urged greater action on climate change in protests across the country.

The students skipped school on Friday to highlight what they say are inadequate climate policies by the Australian government.

On Monday, Australian PM Scott Morrison rebuked their plans for “activism” during school hours and insisted his government was tackling climate change. …

The idea started with Milou Albrect and Harriet O’Shea Carre, both 14, in the state of Victoria. … Milou said: “We want our government to acknowledge publicly that climate change is a crisis. Stop digging coal, stop making new coal mines, switch to renewable energy.” …

Jean Hinchcliffe, 14, saw the idea to protest grow in Victoria and decided to start one in her home city, Sydney. … “Everyone, all young people, we can see that climate change is a real issue and we’re completely sick of politicians’ inaction.

Like with Alexandria Ocasio-Cortez, what would change their minds? How can we convince them they have been misled?

When eventually the carbon dioxide theory is proved to be quite wrong, what will this generation think? Will they […]

Climate Models are a Joke

An update on the graph that is death to climate models

Good people of Earth are spending thousands of billions of dollars to prevent a future predicted by models that we know don’t work. The debate is over, climate spending is an unscientific, pagan, theological quest to change the weather. Just another iteration of what Druids and Witchdoctors have been promising for eons. Don’t expect the vested interests that profit from this Golden Climate Gravy Train to tell you this.

The top 23 global coupled climate models don’t understand the climate and can’t predict it. Our CO2 emissions are accelerating, the effect should be amplifying, but millions of weather balloons and satellites that circle the Earth 24 hours a day show unequivocally that the models are wrong.

BOM homogenization errors are so big they can be seen from space

It’s just not cricket. And in so many ways.

Shame to let a perfectly good dataset go to waste… Australian data comes from some of the longest stations running in the Southern Hemisphere; it could be useful. Instead we get more evidence here that the BOM’s magical and secret homogenization adjustments can take poor data and spread false signals into better data. Homogenisation errors are already visible in a site-by-site analysis, but this shows the problems may be so big they affect averages across the whole of Australia, and we can detect them with satellites.

Tom Quirk continues comparing the satellite record of Australia with the BOM surface version. Previously, he (and for the record, Ken Stewart in 2015) showed that some discrepancies are due to the effect of heavy rain or drought. But now he looks further and finds that not-so-coincidentally, the largest gaps and most “inexplicable” differences occur in the mid nineteen-nineties, the same years the BoM shifted from using old large Stevenson screens to electronic thermometers. Around the same time, the large screens were often also swapped for much smaller ones too — like double jeopardy for data. Oddly, spookily, the BOM makes many adjustments to data […]

Mystery solved: Rain means satellite and surface temps are different. Climate models didn’t predict this…

A funny thing happens when you line up satellite and surface temperatures over Australia. A lot of the time they are very close, but some years the surface records from the Australian Bureau of Meteorology (BOM) are cooler by a full half a degree than the UAH satellite readings. Before anyone yells “adjustments”, this appears to be a real difference of instruments, but solving this mystery turns up a rather major flaw in climate models.

Bill Kininmonth wondered if those cooler-BOM years were also wetter years when more rain fell. So Tom Quirk got the rainfall data and discovered that rainfall in Australia has a large effect on the temperatures recorded by the sensors five feet off the ground. This is what Bill Johnston has shown at individual stations. Damp soil around the Stevenson screens takes more heat to evaporate and keeps maximums lower. In this new work Quirk has looked at the effect right across the country and the years when the satellite estimates diverge from the ground thermometers are indeed the wetter years. Furthermore, it can take up to six months to dry out the ground after a major wet period and for the […]

Sydney “hottest ever” mistake generates fake news

The BOM announced it was the hottest ever day in Sydney today, then realized it had it wrong, but not before headlines spread across the country. For a million dollars a day you’d think the BOM would check their own “high quality” database. A scientific agency would take great care before announcing “historic all time records”for a city of five million people. A shameless PR agency might see that sort of mistake as an advantage.

It’s careless, piled on rank neglect

Even if the day had been “a record”, the temperatures are often artificially inflated due to site changes, thermometer changes, and the one-second-record effect thanks to the introduction of electronic thermometers, all of which are a product of careless BOM management and analysis. And even over and above that, past temperatures have been adjusted or homogenised downwards — often years after they are recorded — and by secret methods that the BOM will not disclose. I’ll have more information soon on changes at Sydney Observatory, that the BOM don’t make any allowance for.

Looks like another one second record?

The BOM announced the record after Penrith hit 47.1 at 1:55pm, the BOM tweet wrongly claimed it had “broken the […]

Australian BoM forced to meet skeptics, answer questions, provide a tiny bit of data

The scandals do count. The Australian articles has got Minister Frydenbergs attention. The extensive collection of blog posts and the IPA Climate Change book show there is a deep well of material to fuel more articles. We have barely begun. Congratulations to Jennifer Marohasy. At least we will get a few more answers to questions we shouldn’t even have to ask.

The head of the Bureau of Meteorology, Andrew Johnson, has been asked by Environment Minister Josh Frydenberg to release extensive temperature data from a weather station in Victoria after requests from an independent scientist.

Dr Johnson has also agreed to meet with Jennifer Marohasy, a senior fellow at the Institute of Public Affairs, to discuss the integrity of the bureau’s temper­ature measurements as she pushes ahead with calls for a parliamentary inquiry.

The story of the “one second” records is potent: How many “hottest ever records” have been created thanks to new electronic equipment?

The Australian Bureau of Meteorology appears to have put in place a measurement system guaranteed to provide new rec­ord high and low temperatures,” she said in the letter.

Instead of the older-style mercury thermometers in which temperatures […]

Poor BOM: Dangerous deniers, amateurs, attacking Australian Bureau of Meteorology, debilitating it by asking questions.

Excellent news. Obviously we are getting to the BoM.

This week, Jen Marohasy and I were mentioned by Maurice Newman in The Australian.“Smoking Gun demands Grilling for the BoM”. In response, the Australian Bureau of Meteorology has unleashed a double dummy-popping effort in The Guardian.

The BoM could have answered the questions in The Australian, of course, but it’s so much easier to whine, bluster, raise the conspiracy flag and avoid the questions that matter at the-ask-no-hard-questions-Guardian.

Former weather bureau chief says agency debilitated by climate deniers’ attacks

Michael Slezak

It really is an extraordinary rant as the former head of the BoM admits skeptics are “debilitating” the BoM with these “attacks”. The Guardian is so starved of real news, it runs the one-sided name-calling excuses and another separate story discusses it as if it was actually news. While The Australian asks the BoM for a reply and would publish it, The Guardian didn’t ask a skeptic. One of these newspapers acts like a newspaper…

How debilitating are we skeptics? Jennifer Marohasy tells me she sent the BoM questions in 2015, but hasn’t […]

Too late: Bureau of Met buys time with another “major revision” of data that was already “best quality” five years ago

Breaking news: Bureau of Meteorology to revamp temperature records, Graham Lloyd reports in The Australian.

We’ve seen this all three times before. As soon as skeptics expose enough scandals in The Australian the BOM has to run and hide behind a “major revision”, a panel, or a review. It’s their pass-out-of-class to not answer questions. It’s too late, I have no expectation that this will achieve anything other than being the excuse de jour for the BOM to keep operating as a PR machine rather than a scientific agency.

In the first round back in February 2011, we worked with Cory Bernardi to request a formal audit of the BOM. They had lauded their “High Quality” or HQ dataset, but suddenly it was not good enough and needed revising. In March 2012 the BOM released an entirely new version called ACORN. The formal audit request was thus “neutralized”, but the new set was as bad as the old set. By July 2012, for free, skeptics analyzed and advised the bureau of a string of pathetic flaws, including that the bureau had “created” nearly a thousand days where minimum temperatures were higher than the maxes, the “hottest day ever recorded in […]

Australian Bureau of Met uses 1 second noise, not like WMO, UK and US standards

Cambridge University Press

The Australian Bureau of Meteorology may not be meeting WMO, UK, US standards

Since the Australian BOM allows for one second “records”, it’s not clear it is even meeting guidelines recommended for amateurs.

The key question: How much of the warming trend in Australia is due to the switch in the mid 1990s from older slower thermometers to new electronic zippy ones that could record every waft of hot air? How many records today are just noise?

If the BOM would release its calibration and comparison data instead of deleting it, we might know. Why won’t they?

Here’s an example graph from Maryborough where the daily maximum was 1.5C above every thirty minute reading. Ouch — are we writing outliers and noise into our history books and climate data bases?

Add “sampling method” and averaging to your skeptical vocabulary. There will be a lot more discussion on these.

BOM Review admits skeptics were right, but say “trust us” it doesn’t matter

The BOM’s bad luck never seems to end. Of all the 695 stations in Australia, 693 worked perfectly, but Jen Marohasy and Lance Pidgeon happened to live near, or have a personal random connection to the only two stations that didn’t — Thredbo and Goulburn. Apparently these stations had been flawed (not fit for purpose) for 10 years and 14 years, but the BOM world-class experts hadn’t noticed. I expect they were just about to discover the flaws when (how inconsiderately) Lance and Jen announced the errors to the world and the BOM were forced to do this pointless 77 page report to stop people asking questions they couldn’t answer.

The nub of this fracas is that something called an MSI1 hardware card was installed in cold locations even though it would never report a temperature below minus 10.4C. Awkwardly this doesn’t explain why the 10.4C appeared in the live feed, then was automatically changed to -10C in the long term data sets which are used for climate analysis. Does the BOM think the dumb public don’t know the difference between -10 and -10.4? Implicitly — the BOM installed the wrong type of card, and also accidentally had an error […]

Pause-deniers finally get busted by mainstream media

It’s been a rotten week for Pause denial

David Rose and the Daily Mail let rip, telling the world that retired NOAA insider, John Bates, was blowing the whistle on how global warming was being exaggerated by scientists to score political points. The hallowed pause-buster paper (Karl et al) broke practically every rule: it was based on misleading “unverified” data processed with a highly experimental, unstable program. There were bugs in the software, the results changed with every run, the data wasn’t archived, and no one could repeat it. They tripled the previous rate of warming by using old-bad-data to adjust better but still-not-very-good-data. They ignored the much better data from ARGO buoys and the satellites (see below) which showed they were wrong. (Rose didn’t even mention that the error bars on the magical adjustment were 17 times larger than the adjustment itself. Too many errors….)

It’s hard oo believe it could be worse, but then the one sole computer holding the program broke, and apparently (what bad luck) none of the eight authors had their own copy either. Nor did the reviewers. The Planet is going to hell, but no one thought to back up the data.

It all […]

What they don’t say about “the hottest ever year” — 20 year warming trend is one third of what models predicted

Don’t mention the trend The warming in the last two decades is 0.06C/decade not 0.22C.

The hottest ever year tells us nothing about the cause of global warming, but the 20 year trend does — and the message from the trend is “the models are wrong”.

Despite the Chinese releasing gigatons of coal fired CO2 into the air, the warming that has happened has been tiny compared to what their models predict. It is so low the Global Worriers won’t talk about the trend. Gone are the days when they would discuss degrees per decade. Meh! The same people who scoffed at skeptics for mentioning one freak season are now reduced to picking on one freak El Nino, and pumping annual tiny fractions of “record” after “record”. If the sun caused global warming (the evidence is there) we’d still be getting warm records, especially in El Nino years. What’s amazing is that after a record El Nino the world hit pretty much the same temperature as it did in 1998.

Dr David Evans has just recalculated the warming trend for the last two decades and found that the warming effect is a big six […]

One third of human emissions and no warming, plus the unholy pursuit of a pause busting paper

For most of this year 2016 was expected to break the 1998 record (which was the hottest year in the UAH satellite data set). But a sudden drop in Dec pulled the yearly average down so that statistically they are indistinguishable.

From one big El Nino year to another big El Nino, we’ve put out one third of all human emissions that have ever been put out since hunter gatherers wandered the steppes, but it appears to have made very little difference.

Thanks to Roy Spencer and global satellites: 2016 not Statistically Warmer than 1998

The top five years in the 38 year satellite record

Does it mean much? Not a heck of a lot. The pause was already long enough to show the models don’t work, and whether or not 2016 was another record is neither here nor there, except as a PR point.

Australian temperatures unchanged for 20 years: Plus Malcolm Roberts first Senate speech is tomorrow

Malcolm Roberts will give his maiden Senate speech tomorrow (Tuesday) at 5pm at the Australian Parliament House in Canberra. To reserve seating contact Leon Ashby leon.ashby AT or phone (02) 6277 3151. He has asked for updated graphs of the UAH data for Australia. His speech may be available via the APH website. (h/t Jim S)

Luckily for us the UAH satellite database can be filtered to track temperatures in the lower troposphere over the Australian land mass. Thanks to John Christy for providing an Australian specific dataset.

We’ve put out a third of all the CO2 homosapiens has ever made in the last 20 years, and it apparently has made no meaningful difference to temperatures here. We’ve put out 60% of all our CO2 since the satellite record began.

Here is the full Australian monthly data from 1979 – now for all seasons graphed below. There are breathless news articles hyping every hot month, every hot week, for records in every little region, and even for a single record hot nights, but no press release to say that temperatures in Australia have not really changed in a meaningful way since 1995.

McKibben: It’s The Climate World War. Hitler, Nazi’s, panic!

When you can’t persuade people to fight your imaginary enemy, declare a war.

New Republic We’re under attack from climate change—and our only hope is to mobilize like we did in WWII.

BY BILL MCKIBBEN August 15, 2016

Translated: Expect 200 million imminent deaths (equivalent to WWII). Give us your firstborn, and lots of your money.

Not quite a dispassionate scientist at work:

In the North this summer, a devastating offensive is underway. Enemy forces have seized huge swaths of territory; with each passing week, another 22,000 square miles of Arctic ice disappears. Experts dispatched to the battlefield in July saw little cause for hope, especially since this siege is one of the oldest fronts in the war. “In 30 years, the area has shrunk approximately by half,” said a scientist who examined the onslaught. “There doesn’t seem anything able to stop this.”

Panic now? In late 2015, Antarctic sea ice shrank by 13 million square kilometers, and nothing seemed to be able to stop it.

Then autumn came. Sea ice is projected to recover by September (like it does every year). Nature is full of cycles. Nothing about the current batch of climate shifts […]

Brian Cox thinks 17,000 employees at NASA always produce perfect graphs. NASA employees disagree. Who to believe?

The key moment making headlines from the Q&A “Science Weak” episode — Brian Cox shows a temperature graph. Malcolm Roberts said the GISS temperature data has been “manipulated”. The Particle Physics Genius’ reply was argument from incredulity: gushing, gratuitous astonishment spread over six attempts to form a complete sentence:

By who? NASA? The people the… Hang on a minute. No, no, see this is quite serious. But can I just – just one thing. NASA, NASA… The people that landed men on the moon?

In a blink of reductio ad absurbum, Cox sweeps aside a potentially useful discussion about thermometers near car-parks, airports, skyscrapers, and mysterious 1,200 km homogenized smoothing. In its place he gives cheap theatrical tricks. Follow his thought to its logical conclusion — everything that NASA does (or presumably will ever do) must be 100% correct. NASA becomes an apostle of the holy order. He treats the brand name as untouchable, but NASA is not just Neil Armstrong and a Big Step, it’s an agency with 17,000 employees. But hey, none of them have ever produced a manipulated graph.

Since experts matter (so Cox tells us) let’s ask the experts — like say, Buzz Aldrin, […]

Malcolm Roberts on Q & A : 1 skeptic against 6 who believe the consensus

On the Eastern side of the country the new skeptical Senator, Malcolm Roberts is on Q & A.

Monday, 15 August 2016

Greg Hunt – Minister for Industry, Innovation & Science Linda Burney – Shadow Minister for Human Services Brian Cox – Particle Physicist and TV Presenter Lily Serna – Mathematician and TV Presenter Malcolm Roberts – One Nation Senator-elect for Qld

As usual it is 6 against 1 the skeptical views that 54% of Australians share. Glaciers will form in hell before the ratio on the ABC would run 1:6 the other way. For Groupthinkers it’s very important that the group discussing a “controversial” topic agrees with each other. This neutralizes any damaging effects of hearing a lone voice put forward counter arguments.

John Cook has sent in a Question about empirical evidence.

Cook points at “less heat escaping to space” – Jo says –this doesn’t mean anything. We assume he means less heat escapes at certain frequencies (which he should have said). Sections of the outgoing spectrum are missing (e.g. Harries et al), which shows that CO2 is stopping some outgoing radiation and is a greenhouse gas (and we knew that already), […]
