Hiding something? BOM throws out Bourke’s hot historic data, changes long cooling trend to warming

Hello Soviet style weather service? On January 3, 1909, an extremely hot 51.7C (125F) was recorded at Bourke.  It’s possibly the hottest ever temperature recorded in a Stephenson Screen in Australia, but the BOM has removed it as a clerical error. There are legitimate questions about the accuracy of records done so long ago — standards were different. But there are very legitimate questions about the BOMs treatment of this historic data. ‘The BOM has also removed the 40 years of weather recorded before 1910, which includes some very hot times. Now we find out the handwritten original notes  from 62 years of the mid 20th Century were supposed to be dumped in 1996 as well. Luckily, these historic documents were saved from the dustbin and quietly kept in private hands instead.

Bourke has one of the longest datasets in Australia — but the BOM, supposedly so concerned about the long term climate trends, appears to have little curiosity in the hot weather of the 1880′s and 1890′s (I talked about the amazing heatwave of 1896 here where hundreds died and people in Bourke escaped on special trains). If it had been a cool spell then, would the BOM feel [...]

EU to change climate with hair dryers, kettles, lawn mowers

You, foolish plebian, thought that a hair dryer was for drying hair. Not so. The purpose of a hair dryer is to change the climate. Let’s stop the storms by slow-mowing the lawn. That sort of thing…

Thus and verily has the EU announced that high-power appliances may now be banned.


EU to ban high-energy hair dryers, smartphones and kettles

European Union to ban dozens of high-wattage household electrical appliances in follow-up to controversial ban on powerful vacuum cleaners

A study ordered by the European Commission, currently in draft form, has identified up to 30 electrical appliances including lawn mowers, smart phones and kettles that could be covered by the EU’s Ecodesign directive outlawing high-wattage devices.

Serfs in the EU will probably spend longer drying their hair, and more time waiting for the kettle to boil  in a quest to produce slightly less CO2. This is in the hope that less CO2 might cool a world that hasn’t really warmed for a decade and a half. It’s a case of not so much blow-drying, and more slow-drying. Likewise, stupid punters may wonder how a lower power kettle can reduce emissions. The laws of [...]

ABC invites BOM and Marohasy to speak — BOM decline, Marohasy accepts, but is cut off?

Bronwen O’Shea, ABC

UPDATED: Correction. The interview was done by a fan of John Cook, not John Cook. Notes in the post and apologies. – Jo

Hm, curious event on the ABC today. Credit to Bronwen O’Shea, host of the ABC morning radio program for the Goulburn Murray, for asking both Jennifer Marohasy and the BOM to discuss the Rutherglen temperature adjustments. Good-o, I say –  public debate and answers! (Note that link is just to their website, I have not found a copy of the interview or transcript).

But everything worked against the ABC. First the BOM chose not to even try to answer. (Hm?)  Then not long after the interview started, the line suddenly went dead and Marohasy was abruptly cut off. She waited for the call back, but it never came. What bad luck eh? Even more unlucky –  when the ABC tried to call her back they got a fan of John Cook on the phone instead*. Then, things got even worse for poor ABC listeners — because the fan of Cook mistakenly thought Rutherglen was different to the surrounding stations, but the BOM raw records say otherwise (see the graph below). UPDATED: Apologies to [...]

Uninformed climate amateurs ask professionals to explain their data revision

David Karoly knew he had to defend the BOM with regard to the hot questions about adjustments to Amberley, Bourke, and Rutherglen data. What he didn’t have were photos of historic equipment, maps of thermometer sites, or quotes from people who took observations. Instead he wielded the magic wand of “peer review” — whereupon questions asked in English are rendered invalid if they are printed in a newspaper instead of a trade-magazine.

Prof David Karoly, Climate Professional called people who ask for explanations poorly informed amateurs. In response, we Poorly Informed Climate Amateurs wonder what it takes to get Climate Professionals to inform us? Instead of hiding behind ‘peer review’, vague complex methods, and the glow of their academic aura, the professionals could act professional and explain exactly what they did to the data?

We discussed the mysterious transformation of Amberley and Rutherglen — where cooling trends became warming trends due to unrecorded site movements that were detected by thermometers hundreds of kilometers away. I also discussed how skeptical scientists have been asking for details for years but the BOM would not provide them. What we still don’t know is why thermometers in 1941 were recording temperatures nearly 2 degrees [...]

Big adjustments? BOM says Rutherglen site shifted, former workers there say “No”

The hot questions for the Australian Bureau of Meteorology (BOM) mount up. Rutherglen was one of the temperature recording stations that was subject to large somewhat mysterious adjustments which turned a slight cooling trend into a strongly warming one. Yet the official notes showed that the site did not move and was a continuous record. On paper, Rutherglen appeared to be ideal — a rare long rural temperature record where measurements had come from the same place since 1913.

The original cooling trend of  – 0.35C was transformed into a +1.73C warming after “homogenisation” by the BOM. To justify that the BOM claims that there may have been an unrecorded shift, and it was “consistent” with the old station starting  further up the slope before it moved down to the hollow.

Today retired scientist Bill Johnston got in touch with Jennifer Marohasy, with me and with Graham Lloyd of The Australian to say that he worked at times at Rutherglen and the official thermometer had not moved. It was always placed where it is now at the bottom of the hollow. That information has already made it into print in The Australian.

The original thermometer records suggest a [...]

BOM finally explains! Cooling changed to warming trends because stations “might” have moved!

It’s the news you’ve been waiting years to hear! Finally we find out the exact details of why the BOM changed two of their best long term sites from cooling trends to warming trends. The massive inexplicable adjustments like these have been discussed on blogs for years. But it was only when Graham Lloyd advised the BOM he would be reporting on this that they finally found time to write three paragraphs on specific stations.

Who knew it would be so hard to get answers. We put in a Senate request for an audit of the BOM datasets in 2011. Ken Stewart, Geoff Sherrington, Des Moore, Bill Johnston, and Jennifer Marohasy have also separately been asking the BOM for details about adjustments on specific BOM sites. (I bet Warwick Hughes has too). The BOM has ignored or circumvented all these, refusing to explain why individual stations were adjusted in detail.

The two provocative articles Lloyd put together last week were  Heat is on over weather bureau  and  Bureau of Meteorology ‘altering climate figures, which I covered here. This is the power of the press at its best. The absence of articles like these, is why I have said the media [...]

Global sea level rise a bit more than 1mm a year for last 50 years, no acceleration

Here’s a novel approach. Beenstock et al  wondered if tide gauges were placed in any old spot around the world or were biased toward area where sea-level did more rising. They compared the location of tide gauges in the year 2000 to sea level rises and falls as measured by satellite altimetry. It turns out the placement seems to be independent (meaning anywhere). This is pretty important because the infernally tough thing about measuring sea levels is whether the land is subsiding or rising at the same time, and how to correct for that. If tide gauges are spread evenly (or quasi-randomly), it means we could average the lot instead of trying to correct and reconstruct each one individually. So that’s what they did – average (they did not reconstruct).

The consensus estimate is that sea-levels are rising by 2mm a year (and 3mm lately, with adjusted satellite data). Beenstock et al used 1,000 tide gauges and found global sea level rise was  more like 1mm a year (very similar to the rise Nils Axel Morner found on that stable spot in Denmark). The conclusion is that sea level is rising slowly at 1mm a year, and that it hasn’t [...]

Man to live on melting iceberg for one year to urge climate change action (An unthreaded thread)

Adrift 2015: The official trailer From Treehugger (where else?)  h/t Climate Depot

 The man pictured above is Alex Bellini, a professional adventurer and motivational speaker who plans to live alone on a melting iceberg off the coast of Greenland for one year, to emphasize the urgent need for climate change action.

Starting in spring of 2015, Bellini plans to find a suitable iceberg in the northwest region of Greenland, where he will remain for up to a year as it slowly melts. Provisioned with with 300 kilograms (661 pounds) of dried food, Bellini will shelter in a survival capsule, the Kevlar-reinforced kind used for ocean oil rigs, until it becomes too risky — at which point he will take to the sea in the capsule, floating adrift until he is rescued.

Treehugger asked:

“Crazy publicity stunt or stroke of daring genius? We’re not sure…

Jo says:

It’s neither and both –  it’s a genius publicity stunt and a stroke of crazy.

The man is a motivational speaker. Assuming he survives, (I hope he does) this’ll set him up for five years of speeches.

(Unless, of course the world cools and everyone realizes [...]

The heat is on. Bureau of Meteorology ‘altering climate figures’ — The Australian

Congratulations to The Australian again for taking the hard road and reporting controversial, hot, documented problems, that few in the Australian media dare to investigate.

How accurate are our national climate datasets when some adjustments turn entire long stable records from cooling trends to warming ones (or visa versa)? Do the headlines of “hottest ever record” (reported to a tenth of a degree) mean much if thermometer data sometimes needs to be dramatically changed 60 years after being recorded?

One of the most extreme examples is a thermometer station in Amberley, Queensland where a cooling trend in minima of 1C per century has been homogenized and become a warming trend of 2.5C per century. This is a station at an airforce base that has no recorded move since 1941, nor had a change in instrumentation. It is a well-maintained site near a perimeter fence, yet the homogenisation process produces a remarkable transformation of the original records, and rather begs the question of how accurately we know Australian trends at all when the thermometers are seemingly so bad at recording the real temperature of an area. Ken Stewart was the first to notice this anomaly and many others when he compared the raw data to [...]

Once in a life time opportunity to be an honest climate modeller — research scholarships!

This is a first! Announcing three scholarships for research-based higher degrees in Australia. Seeking Australian or New Zealand candidates who are science and engineering grads and interested in using neural nets to build climate models that work. This really is something new. Skeptical minds encouraged to apply. Please pass this on to people you think might be interested… – Jo

Once in a Life Time Opportunity to be an Honest Climate Modeller From Jennifer Marohasy

Most critics of anthropogenic global warming, and there are many, never get the opportunity to actually have a go at contributing to climate science in a practical or tangible and constructive way.  That is, they never get to pull a lever, press a button, build a model or make a forecast.  At best they might throw rotten tomatoes by way of blog posts and comments. This is because the tools of modern climate science are very complex and generally run on super computers with restricted access.

But what if it was possible to build your own climate model on a gaming computer, with some help from artificial neural network (ANN) technology?

Artificial neural networks are a form of artificial intelligence and machine learning, that can [...]

EU bans good vacuum cleaners — next big kettles, hot irons?

The Climate Police are coming.

In order to cool the global climate, the European Commission has decided, with infinite wisdom, that companies shall no longer be allowed to make or import vacuums with motors above 1600 watts — which is more than half of the vacuums on the market. These are climate-dangerous machines. They couldn’t just put a health warning with pics of drowning polar bears on the 2200W ones. They must be Verboten! The new rules start on September 1st. I’m sure if they could, they’d arrange a buy-back and amnesty program for high powered vacuums too.

In EUspeak, vacuums are about to get better! Apparently, they will use less energy, save money and pick up more dust too, all that was needed was regulation. (Why didn’t they think of it before?)

The Telegraph

Consumers warned to “act quickly” before top-rated powerful vacuum cleaners sell out forever

The European Commission claims that its new rules, which are intended to help tackle climate change by cutting Europe’s energy usage, will mean consumers “get better vacuum cleaners than ever before”.

The first vacuum was made in 1860. So after 150 years of fine tuning vacuum motors, at last the gifted bureaucrat [...]

New paper shows solar activity is linked to the Greenland climate even 20,000 years ago

This new paper by Adophi et al uses beryllium, oxygen and carbon isotopes from Greenland ice cores right back as far as the depth of the last ice age, 22,500 years ago, and finds there is a link between solar activity and the climate. It follows these proxies of temperature and solar activity as the planet warmed to the start of the Holocene 10,000 years ago.

It is gaining attention in The Daily Mail, with the headline:

Is the SUN driving climate change? Solar activity – ‘and not just humans’ – could be increasing global warming, study claims

During the last glacial maximum, Sweden was covered in a thick ice sheet that stretched all the way down to northern Germany and sea levels were more than 330ft (100m) lower than they are today, because the water was frozen in the extensive ice caps.

‘The study shows an unexpected link between solar activity and climate change,’ Dr Muscheler said in a press release.

‘It shows both that changes in solar activity are nothing new and that solar activity influences the climate, especially on a regional level.

Coal Miner Clive Palmer to host a climate conference for global leaders

Australian politics is pure side-show cabaret.

For Clive Palmer, it’s a smashing winner all the way ’round.  It’s more photo opportunities,  more Palmer-Party headlines, and a chance for him to hobnob with any international names who feel like turning up for a few days of taxpayer funded R&R to his Coolum Resort.

Thus Clive disarms his opponents, networks with the odd VIP, and unnerves the government all at the same time. He can wave the Green flag in future negotiations with Abbott and co, to try to haggle extra bits and pieces in his favour. Plus he distracts people from a messy legal matter with a Chinese firm, and he could certainly use some guests at his 95% empty resort. Which, by the way, is also a legal headache and in the news for all the wrong reasons.

It is a bet that a few politicians wouldn’t mind a Sunshine Coast junket after the G20 on November 17. They get to relax for a few tax-deductible or tax-funded days while they pretend to talk about the insolvable climate problem. Plus it’s a fun way to look compassionate and caring for the third rock from the sun. Everyone earns greenie points, [...]

The crazy world of Renewable Energy Targets

Nothing makes sense about Renewable Energy Targets, except at a “Bumper-Sticker” level. Today the AFR front page suggests* the federal government is shifting to remove the scheme (by closing it to new entrants) rather than just scaling it back. It can’t come a day too soon. Right now, the Greens who care about CO2 emissions should be cheering too. The scheme was designed to promote an  industry, not to cut CO2.

UPDATE: Mathias Cormann later says “that the government’s position was to “keep the renewable energy target in place” SMH.  Mixed messages indeed.

We’ve been sold the idea that if we subsidize “renewable” energy (which produces less CO2) we’d get a world with lower CO2 emissions. But it ain’t so. The fake “free” market in renewables does not remotely achieve what it was advertised to do — the perverse incentives make the RET good for increasing “renewables” but bad for reducing CO2, and, worse, the more wind power you have, the less CO2 you save. Coal fired electricity is so cheap that doing anything other than making it more efficient is a wildly expensive and inefficient way to reduce CO2. But the Greens hate [...]

Help bring Patrick Moore — a Greenpeace founder turned skeptic — to Australia

Case Smit and John Smeed are working to get Patrick Moore to visit Australia soon. Details on how you can help below.

In the video below Patrick Moore talks about his extensive work with Greenpeace during its first 15 years and the useful contributions they made before he split from them because of their increasingly irrational policies.  He’s a powerful, sensible advocate for compassionate reason. This is his journey from eco-warrior to defender of science, logic and the environment. He is a rare man and obviously sceptical of “catastrophic” global warming.

At the Heartland conference July 2014

From Case Smit:

Australia is hosting a “climate information” visit by Dr. Patrick Moore (co-founder of Greenpeace) in October – November this year.  Rather than lecturing to the “converted”, the principal purpose of this visit is for him to meet with opinion leaders in the media, politics and business to convey a rational environmentalist’s views on why policies instituted because of the “catastrophic climate change” scare need to be realistically addressed.


The mental illness of alarmism – climate depression, climate change delusion

Who would have guessed? A relentless propaganda campaign to generate fear about the climate has generated fear about the climate. It takes billions of dollars to generate delusion on this scale.

After hopes for government-run-climates were dashed in Copenhagen, the price of setting up a fantasy came back to haunt the team.  The fallout was psychological pain. The failure of Copenhagen was a savage set-back for the scare campaign in so many ways. Only now, years later, do we hear just how bad the repercussions were.

The answer to “climate fear” is, of course, to look at data skeptically, and to stay logical. But instead, the big-government-NGO machine diverts more money down the deep well of unreason. Now there are research papers analyzing “The Debilitating Disease of Climate Alarmism”, and counselors are (presumably) paid to counsel people on how to be afraid, but not overly so.

What’s the difference between this and a cult? A 17 year old was hospitalized with dehydration because he believed if he didn’t drink water it would help prevent a water shortage. A PhD grad says ““Every time I talked about environmental issues, I would start crying”.

Meanwhile the sensible types quietly leave, and the [...]

How the media distort the news: Lesson 1 — Lies by omission

The Sydney Morning Herald carefully removed the scientific arguments from an article today. Are they afraid their readers are not smart enough to reach the “right” conclusions if exposed to the wrong information? Hey, but its only national policy and billions of dollars at stake.

Today Maurice Newman warned that we are not prepared for climate change (he’s talking about the cold kind). The Australian published his thoughts citing Archibald, Usoskin, Svensmark, Brekke, Lockwood and Curry. Their readers are apparently clever enough to handle discussions of cosmic rays and large hadron colliders.

In Sydney Morning Herald, Latika Bourke and Lisa Cox write an article about Newman’s views, but carefully omit all of the scientific arguments, as well as the potential problems with one sided science funding and the names and credentials of the scientists he talks about. The pair do, however, find space to repeat the litany of the IPCC’s estimate of 95% “probability” (it’s hard to believe Sydney Morning Herald readers have not heard this before).  They don’t mention that the IPCC estimate is a speculative and unscientific number which gets paradoxically higher as the IPCC’s predictions are proven wrong. Nor did they interview Newman and ask him his [...]

Be afraid! Trapped atmospheric waves on the rise. Extreme heatwaves to come.

There are waves piling on waves in the weather.

A new press release tells us that there have been an “exceptional” number of weather extremes in summer.

Weather extremes in the summer — such as the record heat wave in the United States that hit corn farmers and worsened wildfires in 2012 — have reached an exceptional number in the last ten years. Human-made global warming can explain a gradual increase in periods of severe heat, but the observed change in the magnitude and duration of some events is not so easily explained.

Heatwaves lend themselves to headlines. Not only are they scary, but for climate researchers at a loose end, there are 1,000 flavors of wave to comb through. Is that a 3 day, 4 day or 7 day wave you are interested in? Is the cut-off 40C, 38C, 35C or a flexible percentile anomaly above the monthly average? Is it a statewide average, a national record, or a hot week in Houston? Shall we analyze that in seasons, by months, years, or part thereof? The combinations and permutations can keep a supercomputer up late at night. There’s a whole field of cherry trees ripe for the plucking.

It’s an Unsettling Climate for skeptical scientists like Murry Salby

UPDATED: The full text is now available at City Journal. Rupert Darwall is the author of Age of Global Warming (and earning excellent reviews). Darwall has a gift for converting tricky scientific concepts into a story. This month in the City Journal, he beautifully summarizes and updates the story of Murry Salby. He’s interviewed Richard Lindzen and others, and discusses Salby’s work in the context of the way heretics are marginalized.

I helped Rupert with some of the background. It’s controversial science, a complex situation, with irrelevant baggage to boot. But that’s exactly the place where science communicators — or in the case of Rupert, excellent historians — are most keenly needed. The scientists, who are more the numbers-men are the ones who need their stories told, because they are the ones not so inclined to play the PR and networking games. Bureaucratized science attracts and rewards the network players instead, and so it has become that even academia favors the social-climber scientists and grant-players over the people who are more interested in data. (Like modern bureaucratized art, where the grants go to those who are good at getting grants, and the art looks more and more like fingerpainting.)

It’s buttons for global warming! Hello — Climate Change has a new logo

After 4.5 billion years, finally climate change has a new logo.

But even some fans of the the Big Scare Campaign don’t like it. I can’t think why…

(It is dying – the fear of a carbon crisis.)


It looks to me like an inverse-SEO campaign designed by someone deeply afflicted with ASE (Artistic Status Envy — see also its Literary equivalent). Is the aim here just the banal trickery of ambushing the new skeptics who type “It’s not warming” into their search engines? Will gullible teens type in the phrase and find nothing but links to soft-green propaganda? (This could so easily backfire).

Or is this a new form of mental programming for the inductees into the climate faith? Now, when they hear “it’s not warming”, they’ll be getting confirmation — warming means “bad stuff”, now not warming means “bad stuff too!” It’s a form of deep psychology — so deep it’s done right through the magma and come out the other side.

If it looks upside down, that’s because it is.

Jeremy Porter on Grist is not impressed:
