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

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:

Climate change is real because we are snowflake couch potatoes, addicted to netflicks 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 proves climate change is real? The reasoning is [...]

Six weeks ago Australian Met Bureau predicted a dry month for Townsville

Warwick Hughes (h/t Dave Brewer) points out that on Dec 20th the Australian Bureau of Meteorology predicted that the Townsville region had only a 1 in 3 chance of exceeding the average rainfall in January.

Australian Bureau of Meteorology, prediction, Jan 2019 rainfall.

How that turned out one month later:

Australian Bureau of Meteorology, January rainfall, 2019.

Or graphed as the rainfall anomaly rather than as the percentage of the mean:

….

Predicting rainfall in Australia is very difficult. The issue is not that the BoM gets it wrong — it’s that they pretend they can do it that matters. Why bother issuing one month forecasts?

Ten days out they were still hopelessly wrong

As Warwick Hughes notes they also predicted on Jan 17th that February in Townsville would only have a 45% chance of exceeding the average rainfall. The downpour started on Jan 27th.

Today, after one whole week in February, the area has already had over four times the normal rainfall for the whole month, but the BoM didn’t see that rain coming ten days in advance.

The fancy-pants detailed graphics are entirely misleading — like advertising that sells an ability the experts simply [...]

Townsville floods again: 1881, 1892, 1946 and 1953. It’d be climate change if it stopped flooding

After epic flooding in Townsville, witchdoctors are blaming climate change.

 Queensland’s recent extreme weather – bushfires, heatwaves, coral bleaching, drought, Cyclone Penny, Townsville’s floods – showed Queensland is clearly experiencing climate change, Professor Ian Lowe said.

 Thus spake the Druid of Runes waving a bunch of multifactor complex processes that have been happening forever, can’t be predicted and only have scary trends if you draw short graphs with no error bars. Verily we see doom, doth payth my grant, or whatever it is that keeps Prof Ian Lowe going. He is allegedly in the  Queensland Climate Advisory Council (QCAC) — an organization so successful its only existence on the internet appears to be a sidebar on page 15 of a government PDF. But whoever they are, they’re experts, trust us, that the media doesn’t need to ask for an alternate opinion.

Wouldn’t you know it though, floods seem to happen quite a lot in Townsville

This is not to say that the current floods are not serious but just that Townsville is a floody kind of place. It’d be climate change if things stopped flooding in Townsville.

In the last ten days Townsville has had 600mm of rain [...]

John Cook, we’ll believe you when you stop doing what you complain we’re doing

John Cook tries to attack skeptics for their savage jokes about cold spells. Go for it John, we’ll believe you when you when you stop publishing stories about single hot days and tell PhD’s they shouldn’t harp on about random noise like heat waves:

Forecast: flurries of shivering climate-change deniers

When a cold spell struck the east coast recently, US President Donald Trump tweeted “Wouldn’t be bad to have a little of that good old fashioned Global Warming right now!”

The argument he is sarcastically implying and often makes—that global warming isn’t happening because it’s cold outside—possesses an obvious logical flaw. [No kidding]. It’s like arguing that the sun no longer exists when it gets dark at night. Of course, Trump didn’t invent this argument—it’s commonly brought up on denier blogs and social media threads whenever the weather turns cold.

This type of fallacious reasoning is not just common on believer blogs, it’s their bread and butter.

Trump was being sarcastic. Skeptics are making jokes — but what excuse can anyone make for paid PhD’s who are serious?

Let’s swap the hot’s and cold’s of Cooks own words (mine bolded):

The argument PhD’s seriously imply and [...]

Melbourne, 200,000 houses blacked out, 10 companies curtailed, as 1-in-3-year hot day hits

***UPDATED: Melbourne has been 42C or more around 50 times since 1855. That’s one in three years. Thanks to Bob Fernley-Jones for the correction.

 They were only 250 million watts short:

Loy Yang, powering Victoria, and soon probably “taking the blame” too.

Rachel Baxendale, The Australian

h/t Des Moore

More than 200,000 Victorian households had their power cut off yesterday in a bid to protect the state’s energy system from shutting down, as the Andrews government was forced to admit there was not enough power to keep up with soaring demand in sweltering summer heat.

Homes were blacked out, traffic lights across Melbourne were switched off and businesses were forced to close for up to two hours after the Australian Energy Market Operator enforced rolling power outages to make up a 250 megawatt shortfall in supply.

The State Energy Minister (Lily D’Ambrosio) said there would “absolutely” be no blackouts this morning and the rolling blackouts started 90 minutes later. Welcome to the USSAustralia where we hope to make your 150th Birthday Party 0.001 degrees cooler but we can’t predict our electricity grid for the next hour and a half.

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).

1,500 private jets fly in to save world at Davos

Where is your carbon footprint when you need it?

This week the same people who advertise their virtue with climate cloaks are advertising their status with a Bombardier 7500.

Don’t call them hypocrites, it’s completely consistent. Both are pretentious attempts to peck up the order.

More And Bigger Private Jets Landing at Davos as Leaders Discuss Climate Change

Erin Corbett, Fortune

Perhaps its all because of jet envy.

At least 1,500 private jets are slated to arrive in Davos. The number is up from last year’s estimated 1,300, according to the Air Charter Service, which also found that this year’s jets are larger and more expensive.

Why more and bigger jets?

“This is at least in part due to some of the long distances traveled, but also possibly due to business rivals not wanting to be seen to be outdone by one another,” Andy Christie, the private jets director at ACS said in a statement.

 Would you like a helicopter with that? [...]

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 [...]

Climate protests cost $91 billion in lost economic activity, chamber study finds

Climate activists fighting to derail pipelines and other energy projects have blocked $91.9 billion in U.S. economic activity and hundreds of thousands of jobs, according to a new report.

See more at: https://www.globalenergyinstitute.org/infrastructure-lost

There is no Economy B. Once we have wrecked this one….

The report analyzed 15 targeted projects, including the hotly contested Keystone XL pipeline, Constitution Pipeline, and Oregon LNG terminal, as well as New York Gov. Andrew Cuomo’s 2014 fracking ban.

In addition to $91.9 billion in lost economic activity, the protests cost nearly 730,000 job opportunities and $20 billion in tax revenue to federal, state and local governments.

Winning: Huge UN Climate junket only attracts four leaders

2018, Poland: When it comes to national leaders, nobody turned up

The second week of the UNFCCC conferences was always the one where the politicians swarm. But this time the only leaders are the ones from tiny pacific atolls who come in hope of increasing their GDP, one grant at a time.

Ministers – but few leaders – arrive for crucial part of climate talks Nina Chestney, Agnieszka BarteczkoKATOWICE, Poland (Reuters) – Brexit turmoil and French riots have kept many government chiefs away from the final and crucial week of U.N. climate talks, with only four national leaders present on Tuesday.

Out of around 134 national representatives delivering speeches over the next two days, only four are heads of government: the president of Kiribati and the prime ministers of Samoa, the Cook Islands and Tuvalu – nations among the most vulnerable to climate change.

No Leonard Di Caprio either.

If there was real money and power going down here, or leaders thought voters loved climate action, they would be in Poland.

Looks like winning.

SA and Vic at high risk of blackouts this summer

Even the AEMO is warning of blackouts coming, because the BoM is forecasting hot, dry conditions. El Nino on the way, and I hear rumours our Snowy Hydro Dam levels are not great.

There’ll be blackouts this summer if nothing is done, AEMO report warns

Stephanie Dalzell, ABC News

Victoria and South Australia are at a high risk of forced blackouts this summer if no action is taken, according to the latest report by the Australian Energy Market Operator (AEMO).

Not enough supply? Put another million bucks on the BBQ:

To stop that from occurring, the AEMO has sourced emergency energy reserves, which are typically not available to the market and are only accessed when supply is not keeping up with demand.

Those emergency reserves — otherwise known as Reliability and Emergency Reserve Trader (RERT) resources — do not come cheap.

It’s only money:

The report stated that last summer emergency energy cost taxpayers in Victoria and South Australia almost $52 million.

That equated to an average of an extra $6 per household bill.

That’s nothing. The two day heatwave last January burnt up $400 m [...]

ABC Climate fiction: Life at 0.5 degrees hotter, dead plants, animals, ghost towns, jellyfish hell

The job of ABC environment reporters is not to serve the public and ask scientists hard questions about whether we can rely on their climate models that fail 98% of the time and on every scale in time and locality.

Instead their job is to be fiction writers, converting failing models into vomiting babies:

Under IPCC forecasts babies born today will be 22 when warming hits 1.5C. What will life be like?

By environment reporter Nick Kilvert

Meet Casey X. She was born in Alice Springs Hospital on October 13, 2018.

She came into the world screaming, before projectile-vomiting over the hospital floor and falling asleep.

For this the ABC gets $3 million dollars every day.

We are talking about a half degree Celsius of warming spread over 22 years. This is double the decadal rate currently shown by satellites. But even if we assume that climate models are right for the first time ever, and this dramatic change in trends occurs, it’s still only half a degree more in a world where humans live from minus 50C to plus 40C and every day temperatures vary by 10 – 20 degrees.

#DataGate! First ever audit of global temperature data finds freezing tropical islands, boiling towns, boats on land

What were they thinking?

The fate of the planet is at stake, but the key temperature data set used by climate models contains more than 70 different sorts of problems.  Trillions of dollars have been spent because of predictions based on this data – yet even the most baby-basic quality control checks have not been done.

Thanks to Dr John McLean, we see how The IPCC demands for cash rest on freak data, empty fields, Fahrenheit temps recorded as Celsius, mistakes in longitude and latitude, brutal adjustments and even spelling errors.

Why. Why. Why wasn’t this done years ago?

So much for that facade. How can people who care about the climate be so sloppy and amateur with the data?

HadCrut4 Global Temperature, 1850 – 2018.

Absurdity everywhere in Hadley Met Centre data

There are cases of tropical islands recording a monthly average of zero degrees — this is the mean of the daily highs and lows for the month. A spot in Romania spent one whole month averaging minus 45 degrees. One site in Colombia recorded three months of over 80 degrees C. That is so incredibly hot that even the minimums there were [...]
