New Surface Stations Report Released – It’s ‘worse than we thought’

MEDIA ADVISORY: 96% OF U.S. CLIMATE DATA IS CORRUPTED

Official NOAA temperature stations produce corrupted data due to purposeful placement in man-made hot spots

Nationwide study follows up widespread corruption and heat biases found at NOAA stations in 2009, and the heat-bias distortion problem is even worse now

ARLINGTON HEIGHTS, IL (July 27, 2022) – A new study, Corrupted Climate Stations: The Official U.S. Surface Temperature Record Remains Fatally Flawed, finds approximately 96 percent of U.S. temperature stations used to measure climate change fail to meet what the National Oceanic and Atmospheric Administration (NOAA) considers to be “acceptable” and  uncorrupted placement by its own published standards.

The report, published by The Heartland Institute, was compiled via satellite and in-person survey visits to NOAA weather stations that contribute to the “official” land temperature data in the United States. The research shows that 96% of these stations are corrupted by localized effects of urbanization – producing heat-bias because of their close proximity to asphalt, machinery, and other heat-producing, heat-trapping, or heat-accentuating objects. Placing temperature stations in such locations violates NOAA’s own published standards (see section 3.1 at this link), and strongly undermines the legitimacy and the magnitude of the official consensus on long-term climate warming trends in the United States.

“With a 96 percent warm-bias in U.S. temperature measurements, it is impossible to use any statistical methods to derive an accurate climate trend for the U.S.” said Heartland Institute Senior Fellow Anthony Watts, the director of the study. “Data from the stations that have not been corrupted by faulty placement show a rate of warming in the United States reduced by almost half compared to all stations.”

NOAA’s “Requirements and Standards for [National Weather Service] Climate Observations” instructs that temperature data instruments must be “over level terrain (earth or sod) typical of the area around the station and at least 100 feet from any extensive concrete or paved surface.” And that “all attempts will be made to avoid areas where rough terrain or air drainage are proven to result in non-representative temperature data.” This new report shows that instruction is regularly violated.

For more information, or to speak with the authors of this study please contact Vice President and Director of Communications Jim Lakely at jlakely@heartland.org or call/text 312-731-9364.

This new report is a follow up to a March 2009 study, titled “Is the U.S. Surface Temperature Record Reliable? which highlighted a subset of over 1,000 surveyed stations and found 89 percent of stations had heat-bias issues. In April and May 2022, The Heartland Institute’s team of researchers visited many of the same temperature stations as in 2009, plus many not visited before. The new survey sampled 128 NOAA stations, and found the problem of heat-bias has only gotten worse.

“The original 2009 surface stations project demonstrated conclusively that the federal government’s surface temperature monitoring system was broken, with the vast majority of stations not meeting NOAA’s own standards for trustworthiness and quality. Investigations by government watchdogs OIG and GAO confirmed the 2009 report findings,” said H. Sterling Burnett, director of the Arthur B. Robinson Center on Climate and Environment Policy at The Heartland Institute who surveyed NOAA surface stations himself this spring. “This new study is evidence of two things. First, the government is either inept or stubbornly refuses to learn from its mistakes for political reasons. Second, the government’s official temperature record can’t be trusted. It reflects a clear urban heat bias effect, not national temperature trends.”

An example of the bias problem

The chart below, found on page 17 of the report, shows 30 years of data from NOAA temperature stations in the Continental United States (CONUS). The blue lines show recorded temperatures and the trend from stations that comply with NOAA’s published standards. The yellow lines are temperatures taken from stations that are not compliant with those standards (i.e. near artificial hot spots). The red lines are the “official” adjusted temperature released by NOAA.

“If you look at the unperturbed stations that adhere to NOAA’s published standard – ones that are correctly located and free of localized urban heat biases – they display about half the rate of warming compared to perturbed stations that have such biases,” Watts said. “Yet, NOAA continues to use the data from their warm-biased century-old surface temperature networks to produce monthly and yearly reports to the U.S. public on the state of the climate.”

“The issue of localized heat-bias with these stations has been proven in a real-world experiment conducted by NOAA’s laboratory in Oak Ridge, Tennessee and published in a peer reviewed science journal.” Watts added.

“By contrast, NOAA operates a state-of-the-art surface temperature network called the U.S. Climate Reference Network,” Watts said. “It is free of localized heat biases by design, but the data it produces is never mentioned in monthly or yearly climate reports published by NOAA for public consumption.


The Heartland Institute, a free-market think tank founded in 1984, is one of the world’s leading organizations promoting the work of scientists who are skeptical that human activity is causing a climate crisis.

Heartland has hosted 14 International Conferences on Climate Change attended by thousands since 2008, published the six-volume Climate Change Reconsidered series by the Nongovernmental International Panel on Climate Change, and for 21 years has published Environment and Climate News. The Heartland Institute has also published several popular books on the climate, including Why Scientists Disagree About Global Warming (2015), Seven Theories of Climate Change (2010), and Is the U.S. Surface Temperature Record Reliable? (2009).

I would have thought that the surface stations projects in the US would have spawned global weather station auditing by now. I recall there was a group in New Zealand that took the weather felons to court and won. The official “Clime Syndicate” (thnx Mark Steyn) NIWA was ordered to advise that their network is not suitable for climate evaluation.

I’m nor sure what they do now. They voted in one of the stupidest doctrinaire PMs there is who is wiping out their meat farmers industry if Nadern wants an outcome of such policies, UK just slaughtered and burned ⅓ of their hogs (it would have been nice to invite the poor to pick up pork for the price of butchery).

Here is another bit of Clime Syndicate work on Capetown, S.A’s Temperatures (note the the raw temp pattern is identical to that of the US with the 20thC highs in 1930s-40s):

Disgusting, shameful! And now GISS’s Gavin Schmidt has been forced to admit climate models are running a way to hot. And the adjustments to temperature were made to satisfy the CO2 “T Control Knob”. They even have an algorithm that makes hundreds of tiny cumulative adjustments to the aggregate global ‘record) per diem (!) based on this falsified cult science. The Temperature Fiddlers even use ‘station moves and closures to get rid of those not showing warming.

Your memory is very bad:

“In the High Court judgement, released today, Justice Geoffrey Venning ruled that the New Zealand Climate Science Education Trust had not been successful in any of the challenges they brought against NIWA.

Justice Venning also decided that NIWA’s cost should be paid by the trust and he said that if an agreement on the costs could not be reached he would make another ruling at a later stage.”

Well Nick I was wrong on some details but NIWA did fold considerably as a result of the challenge. Here is what happened to NIWA’s iconic ever upwards temp record as a response to the lawsuit:

“But now, para 7(a) of NIWA’s Statement of Defence states that “there is no ‘official’ or formal New Zealand Temperature Record”.

In para 8(b) it says the NZTR is not a public record for the purposes of the Public Records Act, using the exemption of “special collections” defined (in para 4(b)) as non-public records used for “research purposes”.

In para 4, NIWA denies it has any obligation to use the best available data or best scientific techniques, while conceding that it has statutory duties to pursue excellence and to perform its functions efficiently and effectively.

The juxtaposition of these conflicting stances leaves NIWA looking decidedly awkward. Should it go all out to defend its most famous product, or throw the NZTR under a bus?”

The replacement of 7SS doesn’t repeat the Salinger adjustments but it is to include any adjustments agreed between NIWA and BOM, both of whom will supposedly apply state-of-the-art homogenisation technology.

So the old 7SS has already been repudiated. A replacement NZTR is being prepared by NIWA – presumably the best effort they are capable of producing. NZCSC is about to receive what it asked for. On the face of it, there’s nothing much left for the Court to adjudicate.

Big ‘tell’ here: NIWA took out the disputed “Salinger adjustments” and sent the unfinished stuff to the BOM, Australia’s infamous climate fiddlers, to let them adjust it as they see fit!!! Obviously BOM is the big daddy they have to collaborate with (probably had a hand in making NZ temp conforming in the first place). You can’t have New Zealand cooling while big brother next door is approaching meltdown. BOM has mellowed a bit from attacks on their massive adjustments. An eye over the shoulder has that kind of affect.

If you seek a detailed look at what adjustment can do, here is an Excel page from BOM official data for Alice Springs T max daily, adjusted to give in turne versions 1, 2, 2.1 and 2.2. An earlier High Quality set was withdrawn after protest.
These numbers are not like the score for an orchestra to play sublime music. They are the discordant, non-harmonious ramblings of composers without a clue, resulting in white noise.

It’s great to see your comments. Well researched and picking up on others’ exaggerations and errors. It’s a great service for the accuracy of these comment threads. The helpful confirmation for me is that you say nothing substantive to refute the core assertions made in the main post. You clearly have all the available resources, including time, punctuality and extensive knowledge, and remain unable to effectively argue against the bombshell in the main article.

As usual thanks again for the contribution you do therefore make albeit by highlighting your incapability to put a cogent argument forward in this case.

Nick Stroker presents himself as an expert on temperature data, but when asked questions about those data, specifically about infilling and UHI adjustments, he has no answers.
He is no expert.
He is a science fraud.
A defender of al government bureaucrats
as if he is on the payroll.

The weather station siting is bad news, both in 2009 and 2022. Stroker’s response is that NOAA adjusts the data to fix all the siting problems.
How they adjust the data — concerning the details of these adjustments — he has no idea — just trust them. because he says so!

Then Stroker pulls the ultimate sleight of hand.
He insists the USCRN weather stations are sited properly therefore must provide accurate numbers.
That is false.
The numbers from those weather stations are compiled by NOAA government bureaucrats — the same bureaucrats who could not care less that so many other weather stations are not properly sited.

The same bureaucrats who believe in a coming climate crisis and want to see faster temperature rises, because most of them have predicted just that.

We have evidence that NOAA does not care about good science (poor weather station siting) and their employees are biased -“pro-warming”…

But we must trust USCRN because NOAA says it is accurate. And Nick Stroker repeats that claim like a well trained parrot.

The bottom line is we do not know if USCRN is accurate and we do not trust NOAA.

So when Mr, Stroker claims other NOAA data MUST be accurate, because they are similar to USCRN, he is deceiving us.

Both USCRN and other NOAA data could be similarly WRONG.

Having properly sited weather stations does not mean the resulting temperature average reported to the general public will be accurate.

Having properly sited weather stations and an accurate national average temperature does not mean the climate scaremongering will stop.

How many times must climate realists be lied to and deceived about the coming climate crisis (predicted the past 50 years — where is it?)
and falsely blaming bad weather on “climate change” … until we DO NOT TRUST ANY GOVERNMENT CLIMATE DATA
… think of the global cooling from 1940 to 1975 that has mysteriously “disappeared” from the history books. NASA-GISS did that.
Should we trust them now?

And what I have been saying over and over, which is absolutely central to the post, is, let’s look at the results. In the post we read
“By contrast, NOAA operates a state-of-the-art surface temperature network called the U.S. Climate Reference Network,” Watts said. “It is free of localized heat biases by design, but the data it produces is never mentioned in monthly or yearly climate reports published by NOAA for public consumption.

And so I say, again, let’s compare:

Just the same. What happened to that “purposeful placement in man-made hot spots”?

Nick, that is not proof of anything. It makes your argument worse. Without doubt, as Anthony explained above, some sites are very poorly placed to give accurate readings. Therefore they cannot be included in analysis to improve accuracy. The fact that both sets of data from good and bad sites have been fiddled to match each other is not proof of accuracy. Anthony’s graphs show the doubling of warming caused by poor sitingvusing original data. Again, if this is all you’ve got, it increases my confidence in the primary assertion that NOAA can’t be trusted.

The CRN has not been “fiddled.” It is the reference series. Anthony Watts himself acknowledges that the stations in the CRN are well-sighted and maintained, he even laments that they are not more widely displayed. The fact that this pristine reference series matches the ClimDiv network strongly suggests that there are no significant effects from siting issues in the network.

If you want to claim that there’s fraudulent data tampering happening at NOAA with the CRN you’ve got to provide some evidence for that.

jay willis
Reply to  AlanJ
August 3, 2022 9:23 am

Alan, no, you are wrong. Anthony shows that there are major siting issues. Therefore the raw data do not match – he shows this with his graphs. you say:.”pristine reference series matches the ClimDiv network” What do you mean? Some overall average number for the USA? The global average? Some number for the average of the CRN network? What? What adjustments are made to the ClimDev network to ‘match’ the CRN?. Where are the error bars on all these graphs? What’s the variance?

This is all a load of unscientific claptrap in any case. But you can’t have 1). Clear evidence of siting issues + 2). No evidence of siting issues in some aggregated number for some different area. The whole ClimDiv is unfit for purpose, Anthony clearly shows this, and the ‘it all comes out OK in the end’ argument is complete rubbish, and self evidently is bound to cause major errors in the record.

To look at it another way: the siting issues should turn up in the overall network record, or it is unfit for purpose.

Your points are very cogent and well stated. These folks want to use statistics but only part of them, i.e., the mean. Not one of the CAGW proponents will discuss even the minimal piece of statistics that goes along with a mean, e.g., variance.

Although I received pushback about calling variance the amount of data dispersion surrounding the mean on another thread here, I’ve seen no reference that contradicts that definition.

Quoting a mean without also quoting the variance/standard deviation shows how lackadaisical the people calculating the mean are in handling measurement data and how little they care about accurate statistics.

This doesn’t come close to dealing with the uncertainty in measurements or how Significant Digit rules are totally ignored.

Only the mean providing the answer they want is important.

I showed you just above. The US average, which is the measure of warming. Here again is the monthly comparison.

No, that is just faith-based. Your “proof” of siting issues is just a bunch of amateurs going around saying – “Gee, I don’t like the look of that”. No-one has shown that measurements are affected. That the “issues” didn’t turn up in the record is an observation. An actual result. The speculation about bad effects is undone by measurement.

A common tactic of eco-bleeps is to define words differently than most people do.

That’s a standard method of Marxism, which most eco-bleeps believe at heart, and consistent with related ideological teaching that words create reality.

So for example ‘dialogue’ means agreeing with them, not discussion or debate.

They use ‘science’ to support their anti-human agenda.

SOME COMMENTS ON TEMPERATURES

The average temperature has gone up just over 1 C in 100 years.
Temperatures go up and down 5 to 10 C, or more, every day, so that really is not a big deal!
If you step out from the shade on a sunny day, you experience a 10 C or so increase.
The alarm of an increase of 1-plus/100y cannot be justified as catastrophic!

100-plus years ago:

-There were not many weather stations worldwide. They covered less than 2% of the world land area.
– Above the entire ocean area (71% of the planet’s surface), there were no air temperature measurements at all!
– Thermometers were used only on land. Many were not 1) high quality, 2) properly-calibrated, or 3) cross-checked.
– The only accurate data are 42 years of satellite data since 1979. The graph of the data indicates much lower temperatures than of computer-generated graphs, which are based on agenda-driven, massaged/adjusted data 

Thus, the BASE-POINT of the 100y-old temperature reference from which to judge what has happened during the past 100 years is extremely dubious, to say the least.

  • Carbon dioxide is not dangerous. It is about 0.042% in the atmosphere, 4% in exhaled breath,
  • 0.2% in an auditorium or pub, or 5 times greater than in the atmosphere,
  • 0.4 to 0.5% in a submarine, or more than 10 times greater than in the atmosphere. 
  • Submariners live in that safe CO2 environment for periods of 6 months or so.
  • Sea levels have been measured worldwide for well over a century and the level-increase is only about 2mm/year (or less). Some land areas like in Scandinavia are actually subsiding. There is no sea-level crisis anywhere in the world, and no sudden upsurge has been recorded anywhere at all in the world.
  • Artic and Antarctic sea-ice areas and thickness are on average the same for the last 50 years, and within the normal annual ranges. There are no sudden changes anywhere. Floating-ice shelf areas larger than the size of Australia melt every 6 months, and are reinstated in the next months at both poles.
  • Carbon dioxide is the vital ‘food stock’ for all plants, shrubs, crops, and trees. The small increase in carbon dioxide over the last few decades has marvelously caused ‘global greening’, and crop and vegetable yields have risen 15 to 30 percent.

Carbon dioxide is added in actual Green Houses to increase plant and crop growth rates! Carbon dioxide has been a real boon in all food producing countries in the world.

  • It is so important to see that water vapor is over 20 times higher in concentration than carbon dioxide, and is over 50 times more effective with all radiation [over 5,000 higher in concentration than methane, and over 4,000 more effective too with radiation].
  • THE REAL PROBLEMS: The real problems are not the gases themselves, such as carbon dioxide or methane from farming, or from vehicles or industry, but from incomplete combustion and atmospheric pollution (both chemicals and particles).

Pollutants such as heavy metals, unburned carbon particle, dioxins, organic chemicals like benzene and fluorocarbons, toxins, and many more can come from natural fires, all combustion process, industry, volcanic eruptions, and more.

I finally figured it out, you meant the 19th Century. Jesus Christ, is there some God Damn reason people insist on using undefined acronyms & abbreviations? To answer your question here’s what NASA’s Reudy Rito had to say several years ago:

   “Your main concern seems to be why data from 1880 get
   affected by the addition of 2018 January data and a few
   late reports from the end of 2017. To illustrate that,
   assume that a station moves or gets a new instrument
   that is placed in a different location than the old one,
   so that the measured temperatures are now e.g. about
   half a degree higher than before. To make the temperature
   series for that station consistent, you will either have to
   lower all new readings by that amount or to increase the
   old readings once and for all by half a degree. The second
   option is preferred, because you can use future readings
   as they are, rather than having to remember to change

It is fraud. Adjusting has no scientific basis to it. If a station has changed, it is measuring a new microclimate and probably has a new instrument included.

The ONLY reason for ARTIFICIALLY CREATING a long record is for statistical purposes. It IS NOT for a demonstrable instrument calibration purpose since there is no physical proof that the previous instrument was incorrectly calibrated.

If you’re going to adjust one station based on another, then you are just making the information up. That is what homogenization does. It smears temperature information all over the place.

The little ice age flattened out climate change for 400 years before fossil fuel took off. But no scientists ever ask why or how that happened. That’s because there is no money available for the trough to find out. If there were, you can bet there would be all kinds of papers explaining that cooling.

The 2009 surface station study attracted me to this excellent website and this update is great too.

The number of adjustments to the raw temperature data are important too.

More important is the wild guesses — infilling — that can never be verified.

In the 1800s there had to be a lot more infilling than actual measurements.

Even today there is still too much infilling. I do not have accurate numbers — perhaps someone else does — but I believe at least 20% of surface grids have one or more infilled numbers every month. There are areas of the planet where grids are 100% or nearly 100%, infilled numbers — such as in central Africa. Areas where NASA-GISS claim are making high temperature records (TMAX) based solely on NASA-GISS infilling !

Now let’s imagine that the UAH temperature compilation is perfect, and the surface numbers are very similar. There was global warming since the 1970s.

Now consider if that imaginary perfect global average temperature would make a difference to the coming climate crisis scaremongering.
I say no.

Historical temperature records are NOT used for the prediction of climate doom.
The Climate Howlers call for a rate of future warming at least double the rate of warming in the UAH record since 1979. They are not extrapolating prior temperature trends because those trends are not dangerous, and would nor scare anyone.
They are completely ignoring the global cooling from 1940 to 1975 too.

The Climate Howlers scare people by predicting rapid, dangerous warming. Climate Howlers have made the same predictions for the past 50 years, and will probably be making them for the next 50 years too. They program their computers to make the same predictions. And the accuracy of temperature history records will make no difference. The climate predictions of doom will continue to generate fear … while actual global warming since the 1970s has been very pleasant.

It seems to me that most of the world outside of Western Europe and north America is all infill all the time? It seems reasonable that most of the readings we have from the rest of the world back to 1900 are all from cities and likely mostly part of European empires and therefore are far more corrupted by UHI?
I always thought it suspicious the two graphs Hansen had side by side in his 1998 paper, the “world” graph showed far more linear warming?

NASA has deleted the webpage that had this graphic but the Wayback Machine still has it.

And here’s the text of that webpage via the Wayback Machine. Below is Hansen’s lame excuse for why the U.S. temperature profile differs so dramatically from the global temperature profile. Hansen says the U.S. has been following a different course than the rest of the world! No, James, the temperature profile of the world looks just like the U.S. temperature profile with the Early Twentieth Century showing to be as warm or warmer than the present day. Your Hockey Stick Fraud is exposed with your own words.

Hansen: “How can the absence of clear climate change in the United States be reconciled with continued reports of record global temperature? Part of the “answer” is that U.S. climate has been following a different course than global climate, at least so far.”

That’s so lame! He expects people to believe that lie.

Most important is the fact that historic recorded temperatures conform to the temperature profile of the United States where the temperatures in the Early Twentieth Century were just as warm or warmer than today.

When you have the same temperature profile recorded all over the world, then that is the temperature profile of the planet. People can complain that there wasn’t enough coverage of the areas of the Earth, but the areas that *were* covered all show the same temperature profile. All over the world.

And the temperature profile looks nothing like the bogus, bastardized Hockey Stick global temperature lies.

It’s worth considering what may be the most important question:

Do you trust the people compiling the global average temperature number?

Were certain climate beliefs important for getting their jobs?

Do they demonstrate unbiased science and strive for the most accurate measurements possible?

Do they accept new measurement methodologies that could be more accurate, such as satellite data and the USCRN network?

Do they celebrate the Russian INM model that least overpredicts the rate of global warming?

Do they refine their climate models to make more accurate predictions?

Do they publicly predict a coming climate crisis, creating a pro-warming bias with their raw data adjustments and infilling?

Ae there any consequences for wrong climate predictions?

Do they have the freedom to express opinions contrary to the current global warming consensus?

Yeah, the Democrats are carrying out a Soviet-style political show trial.

Of course, they are going to indict Trump. That’s the whole purpose of this political hit job.

They are doing all this in an attempt to prevent Trump from running for president again, because they think he can win and if he wins then they lose their poltical power and their socialist paradise. And Trump has vowed to root the Democrat/Swamp evil doers out, if he gets back in.

The Evil Democrats won’t be successful because Trump has committed no crime. It’s not illegal to question the integrity of an election. It’s not illegal to seek any legal remedy for a corrupt election process. That’s all Trump did.

The Evil Democrats have been trying to nail Trump with something/anything for the last five years, criminally using the power of the federal government to do their dirty work and they *still* haven’t laid a glove on Trump.

Trump is the most vetted, innocent man in American politics. He owes nobody anything and is not obligated to anyone except the American people. The perfect person to clean house in Washington DC.

And Trump is still leading the Republican pack by a substantial margin and he’s not even trying yet.

Trump has to be elected again. Otherwise, the Evil Democrats and their efforts to undermine our government win, and if they win, then the rest of us lose Big Time.

Here I’ll correct that so it is true. Trump is the most vetted, man in American politics. And for good reason. He has numerous charges against him pending. Some of them very serious.

In the graph MoyCRN is my calc from raw CRN data and GHCN_u and GHCN_a are my calc using GHCN unadjusted and adjusted respectively. They all agree to about the same very great extent. This reflects the fact that they are measuring the same thing with very dense station coverage – far more than is needed.

Last time I did it there was a slight warming trend.

This is the best temp monitoring network in the world, and needs wider distribution.
Of course warmists point to its short duration, but it is the best we have got.

I use it often when a warmist says X has become worse in the USA (pine bark beetles, tornadoes, what ever) during the past 10-15 years. Then point them to the USCRN and say, well probably not due to temperature and therefore the hypothetical CO2 caused warming.

The extent of trend is surprising from the graph, but is not apparent by eye because of the shortness of the period. The difference is also surprising, since the curves look very close, but again the short time makes a small difference into a big trend. The difference is probably not statistically significant. I did my own calculation of the spatial averages from station data, with similar results.

The only defect the warmists will point to is the short record length. But is a nice retort to “the past 10-15 years have seen an increase in X in the USA” (pine bark beetles, tornados whatever)
We can point out that any degradation in X must not be due to temperature or the hypothesized influence of the CO2 increase.

A few year ago there was an HURRAY put out by Skeptical Science about a new highest ever temperature. It was at Heathrow. Someone posting on WUWT attempted to get the data for that claim from MET Office, who had reported the claim to the Skeptical Science group. Met office said it was available for a rather large sum of money.

But, it turned out that the data had already been provided to Skeptical Science and was available ON their web site. It showed that the reading lasted only some number of seconds, well below the official 2.5 minute average calculation for electronic temperature sensor stations that can take a reading every second. Investigation showed that the temperature sensors were very near a major runway.

Suggestions that the reading was induced by aircraft operations were vehemently denied as certainly not true, or even possible, by Skeptical Science and other True Believers.

Investigation found that airport security camera recordings were available on-line and that at the exact time of those exceptionally high readings a large passenger jet, just out of the sky, was going right by the sensor position, all jets at full reverse thrust to slow the behemoth. The security camera time stamps matched the MET Office temperature tie stamps. Quiet prevailed thereafter.

Have another cup of coffee and look again.

The “adjustments” lowered the old temperatures from the 40’s through 1980 (easier to get away with lowering old temps than raising new ones) which raises the “adjusted” trend starting in 1970, the 50 year trend that they often quote.

Not only that, but there are UHI biases built into the newer raw data, as bad or even worse than the old data. The new data should have been adjusted down just as much or more. But it wasn’t.

That’s a CLEAR thumbprint on the scale.

The adjustments have very little (<0.1 degrees) impact on the trend since the 1970s. Most of the impact of the adjustments is on the historical trends, and the adjustments lower them. The amount of warming shown in the raw data is greater than the amount of warming shown in the adjusted data.

Simply not true unless the captions of the two curves on your graph are reversed. The raw data shows about the same temperature rise brom 1880 to 1940 (with little CO2) as from 1940 to 2000 (with more CO2) and doing so, falsifies the idea that modern warming is anything special or “unprecedented”.

Reacher51
Reply to  AlanJ
July 27, 2022 9:32 am

The impact on the trend since the 1970s is entirely irrelevant.

The adjustments very obviously make the natural, “pre-anthropogenic” warming of ~1910-1940 look a lot less sharp than it really was, while at the same time make the supposedly anthropogenic warming of ~1980-2020 look much more remarkable relative to the natural warming period that preceded it.

In other words, Hausfather manufactured data to tell a story in which the few decades of recent warming appear to be noticeably different from the warming periods of the past. This is data mangling in service of a narrative, not science.

The amount of warming shown in the raw data is greater than the amount of warming shown in the adjusted data.

When was the last time you had your eyes checked by an optometrist? The issue, because alarmists are blaming humans for causing rising temperatures, is that the trend line for temperatures since the 1940s is steeper in the ‘corrected’ data than the ‘raw’ data.

GISS handles land (and ocean) temperature measurements derived from orbiting satellite instruments, not land based measuring stations.

The corrections indicated in the graph that you provided may not be a “thumb on the scale” type that you insinuate, but instead necessary corrections to adjust for various satellite measurement-introduce errors and/or calibration factors. Hard to say since you did not provide a reference/link to the source of your graph.

As to the whole point of UHI contamination of land-based temperature measurement stations, one would logically expect this to be a world-wide problem since most such station are—for convenience and security and especially for easy access to power and ease-of-maintenance—located in urban areas, quite often at airports near large areas of concrete and/or asphalt.

GISS handles land (and ocean) temperature measurements derived from orbiting satellite instruments, not land based measuring stations.

That is incorrect, from the GISTEMP website:

“The GISS Surface Temperature Analysis ver. 4 (GISTEMP v4) is an estimate of global surface temperature change. Graphs and tables are updated around the middle of every month using current data files from NOAA GHCN v4 (meteorological stations) and ERSST v5 (ocean areas), combined as described in our publications Hansen et al. (2010) and Lenssen et al. (2019). These updated files incorporate reports for the previous month and also late reports and corrections for earlier months.”

Urbanization is indeed a worldwide phenomenon, and adjustments have been developed to handle trend inhomogeneities resulting from it. The US has a fairly unique problem, though, in that it has an incredibly dense surface station network that has been entirely run by volunteers. The bottom line is that the issues Watts’ new survey outlines are very well understood by scientists already and the literature describes the efforts implemented to deal with them. Watts’ new study does not address how adequate those measures are, it’s just dismissing them en masse with little justification.

AlanJ,

Your are correct, and I was wrong in my posting regarding GISS being involved only with satellite temperature measurements.

I should have stated they are involved predominately with satellite temperature measurements:
“A key objective of Goddard Institute for Space Studies research is prediction of climate change in the 21st century. The research combines paleogeological record, analysis of comprehensive global datasets (derived mainly from spacecraft observations), with global models of atmospheric, land surface, and oceanic processes.”
https://en.wikipedia.org/wiki/Goddard_Institute_for_Space_Studies

That being said, I am curious about this statement in your above post:
“Urbanization is indeed a worldwide phenomenon, and adjustments have been developed to handle trend inhomogeneities resulting from it.”
Can you cite a reference or provide a link that gives the details on such “adjustments” . . . I would greatly like to read about such.

Thanks.

See Menne, et al., 2009 “Homogenization of Temperature Series via Pairwise Comparisons.”

AlanJ,

The reference to Menne and Williams [2009] that you alluded to (downloadable pdf available at https://www.ncei.noaa.gov/pub/data/ushcn/v2/monthly/menne-williams2009.pdf ) is fundamentally flawed in its methodology.

The basic flaw is seen in this statement of their “homogenization” approach given in Section 3(a) of their paper:
“The pairwise algorithm starts by finding the 100 nearest
neighbors for each temperature station within a network
of stations.”

Their proposed approach would only work if most of the temperature measuring stations under consideration were fairly sited with respect to the range of the primary variable in question: in this case, possible UHI effect.

However, as the above article clearly points out, approximately 96% of the temperature monitoring stations being evaluated are incorrectly sited, leading to average temperature reporting on the high side for the overwhelming number of stations.

Thus, all the “homogenization” corrections offered by the Meene and Williams approach serve to do is to incorrectly adjust the “outliers”, in this case the fairly sited temperature reporting stations upward in temperature based on the preponderance of their 100 nearest neighboring station having existing UHI bias.

It is laughable to suggest that NOAA has developed such automated adjustments as those offered by Menne and Williams to “handle trend inhomogeneities” resulting from the UHI effect.

The PHA produces almost the same number of downward trend adjustments as upward trend adjustments for the CONUS:

“The PHA produces almost the same number of downward trend adjustments as upward trend adjustments for the CONUS”

Yeah, but I never asserted or implied that some of the UHI-affected stations would not themselves be biased artificially high compared to other 96% of all stations that are incorrectly sited.

The graphical data that you present only goes to show that the “adjustment” for inhomogeneities in the data sets amounts to little more than driving peaks and lows toward the average. That is a mathematically construct . . . not something rooted in reality.

There have been multiple studies that already show that UHI corrections are inadequate. This is easy to see as the trend from properly sited stations (and the satellite land trend) is substantially lower than the “corrected” GISS trend.

Watts’ study showed this. I suspect that you missed this clear and obvious point because you didn’t want to see it.

On your other point, just note that Dressler has a habit of making stuff up and never acknowledges his error – even if he was caught red handed.

UHI is not an error that needs to be corrected – it is a real phenomen that has real impacts on the surface temperature. UHI is fundamentally an oversampling challenge. The language being thrown around on this website is quite inaccurate.

There is also a difference between an “improperly sited” station and a station that is merely located in an urban area. Watts’ analysis makes no distinction as far as I can tell. The graphic shown in the main post is primarily showing a difference between stations situated in urban areas and stations situated in rural areas rather than a difference between badly sited stations and well-sited stations. We don’t want to remove the stations in urban areas from the record, we just want to ensure that they aren’t being oversampled.

You are deflecting. The purpose of the temperature databases as being used is to show what effects CO2 has. That is a totally different subject than UHI being included. If you want to accurately assess the effects of CO2, then you MUST remove the UHI because UHI has a different cause than rising CO2.

That is completely and utterly incorrect. The purpose of the surface temperature analyses is to understand how the surface temperature is changing over time. Figuring out what has caused the observed changes is an independent endeavor to measuring what the observed changes are.

Alan J,
The number of stations in urban or rural places has to be in proportion to the areas of urban and rural in the nation or on the globe. Geoff S
