Oops Climate Commission graph: Queensland warmed nearly 3 degrees in 50 years?

If Alan Jones needs to get “educated” because he got the level of CO2 wrong once, the Climate Commission surely needs to go back to do high school maths, because anyone who has done junior high can see that the running average in the graph below is an impossibility. The latest Climate Commission report: “The Critical Decade: Queensland climate impact and opportunities” starts with blatantly incorrect figure. Since when do “averages” run outside the extreme highs and lows? Thanks to reader Ian E.

Eyeballing this graph suggests Queensland’s average temperature has risen by 2.7 C since the 1950’s.

The text on the same page says: “The average temperature for Queensland has risen by about 1°C since early last century”. So at least the writing matches the official (if exaggerated) records.

Who proof-read this document?

Three professors (Will Steffen, Lesley Hughes, Veena Sahajwalla) and Mr Gerry Hueston, all Climate Commissioners, signed off on it.

The correct graph should look more like this.

Charles Sturt’s time: so hot that thermometers exploded. Was Australia’s hottest day in 1828? 53.9C!

Australia’s hottest day? Not 2010, but 1828 at a blistering 53.9 °C

Back before man-made climate change was frying Australia, when CO2 was around 300ppm, the continent savoured an ideal preindustrial climate, right? (This is the kind of climate we are spending $10bn per annum to get back too?)

We are told today’s climate has more records and more extremes than times gone by, but the few records we have from the early 1800’s are eye-popping. Things were not just hotter, but so wildly hot it burst thermometers. The earliest temperature records we have show that Australia was a land of shocking heatwaves and droughts, except for when it was bitterly cold or raging in flood.

In other words, nothing has changed, except possibly things might not be quite so hot now.

Has North Victoria cooled, and is that the ghost of a solar cycle signal we see?

UPDATED AGAIN #4 — Now with Vukcevics Hale cycle graph of Echuca. and #3 David Archibalds suggestion of the Hale Cycle at work. #2 with Willis Eschenbach’s graph and my thoughts, (see below)

Ian Bryce sent me a striking graph (or two). Looking at the original raw data from Echuca Victoria shows a dramatic cooling trend of nearly half a degree since 1900, and rather than being a siting anomaly, it’s repeated in two towns about 100km away.

Curiously he also finds peaks in the maximums at Echuca that look for all the world like they match the solar cycle. Is it a fluke, or could it be real? If it’s real, what conditions make the solar sun-spot cycle so apparent in Echuca — where its maximum temperatures seemingly peak with each second solar cycle. Can anyone find this signal in other places? — Jo

 

The area is inland Northern Victoria

Threat of ANAO Audit means Australia’s BOM throws out temperature set, starts again, gets same results

Joanne Nova and Ken Stewart

A team of independent auditors, bloggers and scientists went through the the BOM “High Quality” (HQ) dataset and found significant errors, omissions and inexplicable adjustments. The team and Senator Cory Bernardi put in a Parliamentary request to get our Australian National Audit Office to reassess the BOM records. In response, the BOM, clearly afraid of getting audited, and still not providing all the data, code and explanations that were needed, decided to toss out the old so called High Quality (HQ) record, and start again. The old HQ increased the trends by 40% nationally, and 70% in the cities.

So goodbye “HQ”, hello “ACORN”. End result? Much the same.

That meant the ANAO could avoid an audit, since the BOM had changed data-sets, the point of auditing the old set was moot.

For me, this version is so much worse than the previous one. In the HQ data set the errors could have been inadvertent, but now we’ve pointed out the flaws, there can be no excuses for getting it wrong. Instead of fixing the flaws (and thanking the volunteers), it’s almost as if they’ve gone out of their way […]

Has CO2 warmed the planet at all in the last 50 years? It’s harder to tell than you think.

Joint Post: Jo Nova and Tony Cox

Even most skeptics agree that the world has been warming during the last 50 years, but there is apparently no significant underlying warming trend in 46 out of 47 years of data. Something decidedly unusual happened to the world in 1977 and we don’t know for sure what it was. The world got warmer, and the change “stuck”. But there were no extra emissions of CO2 in that year, so there is no reason to pin this to CO2.

It’s difficult to believe we are not sure – but the last 50 years of warming trend depends on that single stepwise leap in 1977. Look at the graph below. Does it show one strong underlying warming trend, or is it really a trend so insignificant that it wouldn’t exist if there was not a step change that artificially bolstered it?

A series of two flat lines can appear to be a continuous warming trend if a linear trend line is fitted because it ignores the step change. McKitrick and Voselgang

This step effect was first noted by David Stockwell in 2009

The continuous warming appears to be obvious in the records of […]

Australian temperature records shoddy, inaccurate, unreliable. Surprise!

The BOM say their temperature records are high quality. An independent audit team has just produced a report showing that as many as 85 -95% of all Australian sites in the pre-Celsius era (before 1972) did not comply with the BOM’s own stipulations. The audit shows 20-30% of all the measurements back then were rounded or possibly truncated. Even modern electronic equipment was at times, so faulty and unmonitored that one station rounded all the readings for nearly 10 years! These sloppy errors may have created an artificial warming trend. The BOM are issuing pronouncements of trends to two decimal places like this one in the BOM’s Annual Climate Summary 2011 of “0.52 °C above average” yet relying on patchy data that did not meet its own compliance standards around half the time. It’s doubtful they can justify one decimal place, let alone two?

We need a professional audit.

 

A team of independent engineers, scientists, statisticians and data analysts (brought together by the joannenova blog) has been going through the Australia Bureau of Meteorology records (BOM). They’ve audited some 8.5 million daily observations across 237 High Quality and other close sites in Australia. Shockingly, while […]

THAT famous email explained and the first Volunteer Global Warming Skeptic

Years before Climategate, THAT email, from Phil Jones to Warwick Hughes told us everything we needed to know about the scientific standards at the Climate Research Unit of East Anglia. THAT email was the tip of the iceberg, and below is what lay underneath the surface — the things that were said behind the scenes at the time. Geoff Sherrington has pieced together a sequence of climategate emails, his own emails, and parts of Warwick Hughes work to recreate the sequence.

And for the true skeptic-aficionados, here’s a new layer of history to the skeptical chronology. Where did this volunteer audit movement begin?

Who would have guessed that at least one skeptic, Hughes, was asking for the data Phil Jones worked with, as long ago as 1991? (That was way back in the days where people worked with hard copy print outs, and drew graphs by hand!) Does Hughes rank as volunteer Skeptic Number 1?

UPDATE: I asked Warwick, and he thinks the first unpaid skeptic was Fred Wood in 1988*. — Jo

Messages from the global raw rural data. Warnings, gotcha’s and tree ring divergence explained!

Have you wondered what the global raw rural data tells us?

What did those thermometers say before the adjustments, smoothing, selection, and averaging?

This just might be the first time anyone has publicly compared the global raw data to published adjusted data sets in this way.

Frank Lansner has been dedicated in the extreme, and has developed a comprehensive Rural Unadjusted Temperature Index, or RUTI. One of the most interesting points to come out of this extensive work is the striking difference between coastal stations and inland stations. Frank kept noticing that the trend of the inland stations was markedly different from coastal stations and island stations.

Fig1. Red-Blue lines mark regions where there was a different coastal to inland trend. In green areas the two trends were similar.

What he finds is perhaps not so unusual: The coastal areas are heavily influenced by the sea surface temperature. Inland stations record larger rises and falls in temperature, which is hardly surprising. But, the implications are potentially large. When records from some stations are smoothed over vast distances (as in 1200 km smoothing), results can be heavily skewed by allowing coastal trends to be smoothed across inland areas. What Lansner […]

Was 2010 the hottest ever?

Was 2010 “the hottest year ever” as the PR machine repeats ad nauseum? Yes — but only if you ignore three of the four main global datasets and those awkward questions about why nobody thought to put thermometers in better places.

Run your eyes down this page to see how the GISS temperatures pan out compared to all the other compilations. This is James Hansen’s group, and GISS stands for the Goddard Institute of Space Studies — and in the topsy-turvey world of climate change, that’s apt — the space centre and hot bed of rocketry calculates world temperatures by ignoring … satellites. For GISS, measuring the world temperature, calls for irregularly spaced, unique, non-standardized temperature stations (sometimes near air-conditioning vents and concrete). And no sir, not the satellites that scan the Earth 24 hours a day, over land and sea, and which are usually not too close to exhaust vents, or buildings, or (thank goodness) fermenting vats of sewage either.

So, indeed, the only sane answer to the cherry picking crowd who crow triumphantly about their outlying most favorite result, is that “No” 2010 was not hotter than 1998, not according to the satellites. And even if it had […]

Announcing a formal request for the Auditor General to audit the Australian BOM

A team of skeptical scientists, citizens, and an Australian Senator have lodged a formal request with the Australian National Audit Office (ANAO) to have the BOM and CSIRO audited.

The BOM claim their adjustments are “neutral” yet Ken Stewart showed that the trend in the raw figures for our whole continent has been adjusted up by 40%. The stakes are high. Australians could have to pay something in the order of $870 million dollars thanks to the Kyoto protocol, and the first four years of the Emissions Trading Scheme was expected to cost Australian industry (and hence Australian shareholders and consumers) nearly $50 billion dollars.

Given the stakes, the Australian people deserve to know they are getting transparent, high quality data from the Bureau of Meteorology (BOM). The small cost of the audit is nothing in comparison with the money at stake for all Australians. We need the full explanations of why individual stations have been adjusted repeatedly and non-randomly, and why adjustments were made decades after the measurements were taken. We need an audit of surface stations. (Are Australian stations as badly manipulated and poorly sited as the US stations? Who knows?)

Australia’s High Quality Data: 12-year-sites used for “long term” trends

 

What would you say if you knew our high quality temperature record included sites with 100 year long “records” which were based on just 12 years of data and some undisclosed method was used to construct 90% of the graph?

Wow? I mean, Wow?! Why are these sites with such little actual data being included in a series called “high quality”?

Presumably the “adjusted” trends were recreated (in a sense) by homogenizing data from nearby stations, but why not use just the stations with long records in the first place? Out in the vast outback there are long distances between stations, and while a “splice” might overlap for ten years, who knows whether the dramatic PDO oscillations don’t shift weather patterns during their 30 year cycle and mean that any ten year period is not indicative of the longer time frame.

BOM compensate for the Urban Heat Island effect by making adjustments that essentially result in almost no change in the trend. They remove the “urban” stations, but UHI affects even small populations, and Andrew Barnham speculates that the largest changes in the UHI effect may occur in these smaller rural locations that are still included.

Andrew […]

Australian Temperatures in cities adjusted up by 70%!?

Ken Stewart has been hard at work again, this time analyzing the Australian urban records. While he expected that the cities and towns would show a larger rise than records in the country due to the Urban Heat Island Effect, what he found was that the raw records showed only a 0.4 degree rise, less than the rural records which went from a raw 0.6 to an adjusted 0.85 (a rise of 40%). What shocked him about the urban records were the adjustments… making the trend a full 70% warmer.

The largest adjustments to the raw records are cooling ones in the middle of last century. So 50 years after the measurements were recorded, officials realized they were artificially too high? Hopefully someone who knows can explain why so many thermometers were overestimating temperatures in the first half of the 1900’s.

50 years later?

The raw Australian urban temperature records are in blue. The adjusted records in red. Note that temperatures in the middle of last century appear to be adjusted downwards. These are the annual average recordings for all 34 sites.

Did GISS discover 30% more land in the Northern Hemisphere?

… 😮 UPDATED with GLOBAL values! The questions get bigger. (See below) July 18th.

Frank Lansner has been a busy man, and he’s asking some very thought provoking questions.

The Northern Hemisphere has a ratio of 40% land to 60% oceans, and the Hadley Met Centre seems to use a similar ratio (NH HadCrut Series: 58% ocean, 42% land). But Frank Lansner wondered why, when he graphed the GISS land-data-set alongside the combined-sea-surface-temperatures (CSST), GISS comes up with an “averaged” line that runs much closer to the land data set and not the sea surface set. If it were weighted 60:40 (ocean:land) the combined Northern Hemisphere line ought to run slightly closer to the ocean based temperatures.

So Lansner mixed the land and sea temperatures in different ratios and graphed them and an odd thing occurred. Perhaps there is some good reason for it, but the GISS NH average line is currently running close to a mix that could be almost 70% land, and only 30% ocean. Back in 1985 the NH Average was closer to the sea temps as would be expected. In fact as late as 1995, the NH line still ran at around 40% land area. But […]

The BOM & CSIRO report: It’s what they don’t say that matters

Ken Stewart has scanned the trend maps at BOM (Bureau of Meteorology), and his point is spot on. As soon as I saw the neat joint six page advertising pamphlet for the climate-theory-backed-by-bankers, I wondered what happened to the first 60 years of last century, and Ken found it. Did the BOM forget they have hundreds of data points from back then? Did they forget to use their own Website, where you can pick-a-trend, any-trend, and choose the one with err…more convenient results? Or is it the case that their collective mission is not necessarily to provide Australians with the most complete and appropriate information available, but with what the bureaucracy needs them to know? And what they need them to know, apparently, is the carefully censored version of the truth that will keep government ministers happy (Let us tax them more!), keep department heads smiling (Let the climate cash cow continue!), and last, but not least, help staff feel good (We’re sure we’re helping the environment!).

Why censor half their own data?

The trend map page works exquisitely well (I am happy to praise the BOM Web site team). Compare these two trend maps:

Is there any unmassaged data out there?

This is yet another example of things that don’t add up in the world of GISS temperatures in Australia. Previously, we’ve discussed Gladstone and Darwin.

Ken Stewart has been doing some homework, and you can see all the graphs on his blog. Essentially, the Bureau of Met in Australia provides data for Mt. Isa that shows a warming trend of about 0.5 degrees of warming over a century. GISS takes this, adjusts it carefully to “homogenize urban data with rural data”, and gets an answer of 1.1 degrees. (Ironically among other things, “homogenisation” is supposed to compensate for the Urban Heat Island Effect, which would artificially inflate the trend in urban centers.)

To give you an idea of scale, the nearest station is at Cloncurry, 106km east (where a flat trend of 0.05 or so appears in the graph). But, there are other trends that are warmer in other stations. Averaging the five nearest rural stations gives about 0.6 degrees; averaging the nearest ten stations gives between 0.6 and 0.88 degrees.

Horrifying examples of deliberate tampering

Just when you thought it couldn’t get worse for the cult of the carbon scare.

Now we need to ask if the world has even warmed? I’ve always said, “global warming is real”, but the recent exposés of shocking corruption in science have made me start to wonder whether even that is true.

Today a study by Joe D’Aleo and Anthony Watts, was announced by the Science and Public Policy Institute (SPPI).

From their media release:

An extensive survey of the literature and data regarding ground and sea surface temperature records uncovers deception through data manipulation, reports the Science and Public Policy Institute (SPPI).

Authors veteran meteorologists Joe d’Aleo and Anthony Watts analyzed temperature records from all around the world for a major SPPI paper, Surface Temperature Records – Policy-driven Deception? The startling conclusion that we cannot tell whether there was any significant “global warming” at all in the 20th century is based on numerous astonishing examples of manipulation and exaggeration of the true level and rate of “global warming”.

That is to say, leading meteorological institutions in the USA and around the world have so systematically tampered with instrumental temperature data that it […]

Smoking guns across Australia: Where’s the warming? Looking at 16 other locations

If there was enough money, fame and power on the table (think seismic proportions, money that moves the economic landscape), would it be possible to take a small unproven scientific theory as an excuse and, with the best PR teams in the world, promote it, support it, and make it appear unquestionable?

If it were cloaked in the most “innocent” of motives, and shrouded in terminology that veils the truth, would it not run unchecked for years, unless some big vested interest opposed it? And if there was no particular big vested interest to oppose it, isn’t it possible that if the only harm it causes is to the giant disorganized mass known as humankind, there would be no committee of humankind to check its momentum.

On Watts Up tonight, we get some insight into just one specific example of how corrupt science can be. It’s yet another day in the history of the climate-scam where people may say years from now… remember that night we got the news about Darwin? Thanks to Willis Eschenbach’s dedicated analysis.

Goldilocks graphs: not too close, not too far

Have you noticed, the scaremongers are being boxed into reusing the same graph over and over. We sceptics are not afraid of any graph, but alarmists just don’t want to look from too close or too far away…

When skeptics debunk a graph we show the graph we debunk. Not so the carbon-is-a-crisis crowd. The latest trend in graphology-PR is to debunk sceptics graphs by ignoring the graph itself and putting up an entirely different graph.

Ocean temperatures: the new bluff in alarmism

There are 2014 updates on this topic:

Ocean temperatures – Is that warming statistically significant? IPCC in denial. “Just-so” excuses use ocean heat to hide their failure.

There has been a change in direction by the alarmists, as shown by their new “Synthesis Report.” The independent scientists noticed it during the Wong-Fielding meeting.

The alarmists have abandoned air temperatures as a measure of global temperature, because the air temperature graphs are just too hard to argue with (like the second figure below, from the Skeptics Handbook). Instead they’ve switched to ocean temperatures, which they often disguise as ocean heat content (a huge number like 15×10²² Joules sounds much more scary than the warming it implies of 0.003° C/year).

All three pages of the Synthesis Report that deal with ‘evidence’ are about factors or trends that tell us nothing about whether or not the warming is due to carbon emissions. If God put the galaxy in a toaster, sea levels would rise, ocean heat content would increase, and ice would melt.

Notice how the graph above from the Synthesis Report that came out this month doesn’t include the last six years of data? Carrier pigeons from the remote worldwide […]
