LIVE – Corrupted Climate Stations

Watch Anthony Watts discuss his latest report at NOON CDT

A new bombshell report found that 96% of the National Oceanic and Atmospheric Administration (NOAA) temperature stations produce corrupted data due to purposeful placement in man-made hot spots. These stations fail to meet the published standards deemed “acceptable” by NOAA itself.This 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.This report eviscerates the media’s narrative that the Earth is seeing runaway global warming.

Has the Earth warmed over the last 20 years? Yes. Has it warmed to the degree the media claims? No.

And most importantly, is it catastrophic? Absolutely not.

Anthony Watts, director of the study, takes the reins for today’s Climate Change Roundtable to provide definitive evidence that the temperature record is flawed. You don’t want to miss this. We go live with the findings at 12pm CT today.

I suppose it shouldn’t be surprising to hear people in cities complaining it feels hotter, because it IS hotter in cites from the Urban Heat Island (UHI). Since a healthy majority of people in the world now live in very large cities, it is easier to convince them the whole planet is warming more, when their urban/city surroundings are actually a whole lot warmer than the rural countryside. So it is true for the people in the cities that their world is warming. But the city urban interface is only a tiny fraction of the percentage of the global land surface.

Undoubtedly a lot of the temperature record has suffered a similar fate over many years of official temperature measurements. And then the adjustments. Not only corrupted data collection from poorly cited and urban placed measuring, but then someone fiddling with the data to say what they think it should have been, so it shouldn’t be surprising that we get ‘warming’ in the data.

Getting an honest temperature measurement has to be the goal of every meteorologist and especially for real scientists that then use that data to advise politicians on national and global policy to now try and ‘change the weather’. All this IS the crux of the matter.

It was hot during the summer in large cities in 1960m 1980, 2000 and 2020.
It is always hot in the summer in big cities.
But people live the anyway.

Warming from UHO is most likely to have much effect on an inner city weather station from let’s say 1970 to 2020. But a rural station in 1970, that is now surrounded by a small town in 2020, may have a large UHI effect

Of course 70% of the world is oceans, where UHI does not apply.

Economic growth in the vicinity of any weather station could cause some UHI.
Even formerly rural weather stations.

Perhaps what’s needed is a graphic of how original recorded temp measurements are “treated” to arrive at the derived published numbers that bureaucracies and media serve up to the public –

  • Infilling
  • Spacial Area Weighting
  • Pairing
  • Homogenizing
  • Averaging

And all the time we’re being warned about the evils & dangers of “misinformation” and “disinformation”.

Adjustments change actual raw data into a judgement of what the data would have been if measured correctly in the first place. Data no longer exist after adjustments,

Weather statin siting is external evidence of
scientific integrity. The evidence clearly shows
that siting does not matter to NOAA, has not been improved since 2009, and no organization that cares about accuracy would allow so many poorly sited weather stations. Such an organization can not be trusted.

You REDUCE bias by using properly sited weather stations whose data is compiled by people with no bias.

Not improperly sited weather stations whose data is compiled by people who all believe in a coming global warming crisis, have predicted rapid global warming for many decades, and want the temperature numbers they report to the public to verify the climate predictions they have been making for decades.

If NOAA had integrity, they would never predict medium or long-term climate. Humans have never demonstrated any ability to correctly predict medium or lomg-term climate or weather trends. Any weather prediction beyond a week or two is likely to be wrong. NOAA’s Atlantic Hurricane forecasts are usually wrong. I consider them to be a medium-term prediction.

Nobody is saying the ClimDiv data aren’t adjusted, we’re saying the adjustments bring it perfectly into line with the perfect reference data, so it would appear that the adjustments are performing exactly as they’re supposed to perform.

And there is no need for trust – the raw data are available, the methodology is meticulously described in the literature. If you don’t trust the NOAA to perform the adjustments as they claim then go do them yourself. Produce your own surface temp analysis, describe your methods, and post it for all of us to see.

A simple request Nick:

Let’s see that same plot that you posted using the raw datasets from both USCRN and ClimDIV, and how about at the same time we go to a 7-day running average instead of using a camouflaging 12-month running mean.

Why a seven day running mean? That would by the minimum time span to smooth out UHI effects that would vary with urban heat-release activity variation over the five normal workdays versus Saturday/Sunday weekends.

Reply to  Gordon A. Dressler

The plot is based on monthly averages, which is what you get in ClimDiv/GHCN. It uses raw USCRN (there isn’t any other kind) and GHCN_u is the unadjusted GHCN, which is pretty much the ClimDiv set.

Here is the plot without 12-month smoothing:

With the NOAA USCRN as a check and balance, one would assume that NOAA’s other datasets would be similar — they would not want to publicly contradict themselves. But that is a risky assumption.

Of course the first step in data analysis, which Nick Strokes could never even imagine, is to judge the credibility of the people who compile the data.

Do their actions demonstrate a lack of bias and a strong concern for accurate measurements?

For NOAA and NASA-GISS, my answer is “no”

Poor siting of US weather stations

Claiming pre-1900 N.H. numbers are “global”

Claiming false margins of error of +/- 0.1 degree C.
when there is lots of infilling of numbers
that can never be verified.

Hiding the amount of infilling in their numbers,
especially in the 1880 to 1920 period.

Making predictions of rapid dangerous global warming
for decades … that never happens

That adds up to organizations who can’t be trusted.
,
Therefore, no logical reason exists to trust
USCRN data.

Since NOAA can’t be trusted, then USCRN can’t be trusted, and it USCRN can not be a check and balance for other NOAA temperature data compilations.
All could be wrong — similar, but wrong !

Because the organization can’t be trusted.

I’m confident most people here would agree with this argument, except Nick Strokes, who defends government bureaucrat temperature data las if he is in charge of compiling it, or at least on the NOAA payroll.

Yet when asked questions about the data which require numerical answers, Strokes responds with generic word salads. So it seems that people who blindly defend NOAA and NASA-GISS data can’t be trusted either!

USCRN 3.10 °C/century
ClimDiv 1.96 °C/century
These are actually quite high trends, but very uncertain because of the short period. FWIW, USCRN gives the higher trend, even though the point values of the two data averages are very close. Again that reflects the uncertainty of the short interval.

Without infilling, you have just the temperatures inside a few thousand boxes. The only way you can relate this sample to the region they are sampling, is by infilling. ClimDiv and I may do it with different method, but we get the same results.

Correct. That’s all you have. To infill you have to make assumptions and the number of infilled values exceeds the number of datapoints.

Reply to  Nick Stokes

Infilling does not create raw data.

It is a guess of what data would have been if correctly measured in the first place and can never be verified.

The infilled numbers are whatever government bureaucrats want them to be. If the bureaucrats are biased pro- warming, their infilled number may reflect their bias.

(1) More important is knowing how many surface grids have infilled data in a typical month.

(2) And the average number of data points that are infilled in an average month.

You come here implying you are an expert on temperature data collection.

If you are an expert, you will know the answer to my questions (1) and (2) on exactly how much infilling is done.

I’m interested in the right answer.
Not just any “answer”.

(3) And I’d like to know how any margin of error for the global average temperature can be calculated if there are infilled numbers that are never verified for accuracy.

It is my judgement that you do not know the answers, and therefore you are no expert on temperature data.
Without knowing those answers, it is puzzling why you try so hard to defend the surface global average temperature calculations.

No, that is totally unimportant. Grids are an artificial construct. If you make small cells, many will be empty. I repeat, all you have is point readings. Attributing the grid temperature to that of the measures within is already infilling. Every point that you haven’t actually measured is infilled. And the point of proper sampling is that you can do that.

So the answer to (2) is that they are all infilled.

On (3), you can verify, and people do. The justification for infilling is that you can accurately interpolate. So you can take half the readings, say, and see if you can interpolate the other half. If you can, then interpolating from the full set of readings is likely to be effective.

The classic paper on sampling uncertainty, the main uncertainty in global temperature, is Brohan et al 2006

More important is knowing how many surface grids have infilled data in a typical month.

To this point, the individual station series are not being infilled for missing data points when anomalies are being used – this is one great benefit of using anomalies.

The “infilling” being done is simply that every square mm of earth’s surface is not blanketed by weather stations, and so we necessarily use the places where we do have measurements to represent all the spaces in between. That this is valid for temperature anomalies is common sense from our every day experience – if it is a hotter than normal day at my house it is almost definitely a hotter than normal day a few miles from me, too.

This approach is common in many geospatial applications – for instance I don’t need to measure elevation at an infinite number of dimensionless points on a hillside to get a very robust estimate of the topography – I can measure a finite number of points and infill between them all. There are limits (two points is probably not enough), but those limits can be systematically assessed and we can perform adequate sampling.

What if there are no weather stations at all in your neighborhood (grid) ?

And would you claim a +/- 0.1 degree C. margin of error when there is infilling that can never be verified for accuracy?

Correct. In Climate Science, most especially in the temperature domain (as opposed to Sea Level Rise or Ocean Acidification), there is a lack of a control group, or rather, the control group (i.e. undisturbed stations) is eliminated by absorption. Instead of trying to explain the difference between the undisturbed stations and the ones that are influenced by human activity in theoretical terms, the difference is presumed to be an artifice that needs correction. I think that may be because theory states that CO2 is well mixed, so it’s difficult to explain why the undisturbed stations aren’t showing much warming. They tend to falsify theory.

Since NOAA publishes USCRN data since 1975 and USHRN data too, it would be very alarming if there was more than a small mismatch. But USCRN does not verify USHCN data from 1880 to 2005.

Even worse is that NASA-GISS claims to publish a global average temperature from 1880, when there were too few land weather station in the Southern Hemisphere before 1920, and not enough of them before 1950.

In addition, sea surface temperatures were mainly measured in Northern Hemisphere sea lanes with buckets and thermometers, with far too few S,H. measurements.

Not that long ago, pre-1900 average temperature data were described as “Northen Hemisphere.
Based on the surface coverage outside the US and Europe pre-1900, the phrase “rough estimate of the Northern Hemisphere average temperature”
would have been more accurate.

Now we have NASA-GISS “global” averages since 1880, and HadCRUT claims an even less believable “global” average since 1850. The “global” claim is science fraud.

Even worse is the claimed tiny margin of error.
+/- 0.1 degree C. the last time I looked.
Whatever margin of error is claimed is science
fraud — no margin of error can be calculated
with so much unverified data infilling.

They are not really global averages before 1900
— they are rough Northern Hemisphere averages.
so official claims that they are “global” averages
are science fraud,

Puerile lies (ably demonstrated on this site already) written by a shill on behalf of fossil fuel interests. Who would touch it with a barge pole. But he could have at least made it 97% for irony’s sake.

This is a big so what. So what if temps increased over recent times. Natural variabilities of the sun’s output is the likely culprit. Better warmer than colder. Trying to imply that CO2 is the culprit with no empirical evidence is a fools errand. Show us the proof or STFU. And btw, the Earth’s atmosphere is not a greenhouse and CO2 can’t retain heat like the fraudsters claim it can.

The only 2006 study I found did not say what you claimed:

FROM THE ABSTRACT:
“Holocene climate proxies suggest substantial correlations between tropical meteorology and solar variations, but these have thus far not been explained…. Using a coupled ocean-atmosphere-composition model …”

The key words are “climate proxies”, “tropics” and
“models”. This may not be the study you were referring to, but it is obvious what the NASA-GOSS position is today — declining solar energy for over the past 50 years.

Abstract is here:

Pubs.GISS: Shindell et al. 2006: Solar and anthropogenic forcing of tropical hydrology (nasa.gov)

NASA-GISS shows lower solar energy since the 1950s.
July 2020 data

They present solar irradiance since 1880, but I can’t imagine any accuracy before the satellite age in the 1970s.

Correct—the only solar irradiance measurements that go back that far were ground, using thermopile instruments. The absolute cavity radiometer was not invented until the mid-60s (by a guy from JPL). A model would have to be used to convert the ground irradiance into top-of-the-atmosphere irradiance.

The article was from http://www.space.com. The study was conducted by a team of international scientists in 2006 examining meteorites. The study claims a significant increase in the sun’s output from 1880 through the end of the 20th century. Although it does say that the peak was reached in 1950 but the solar output remained at this higher threshold through the end of the 20th century.

Yes, of course they are different. Those are the old Melbourne site (for which WUWT clamored for replacement) and the new one. They have run them in parallel for 18 months to check for the difference, before switching to the new one. The well-established difference of 0.8°C for Tmax will now become an adjustment. Do you think they should not make that adjustment?

Nick,
That difference between two stations a mile apart might average 0.8 deg C but that is 0.8 +/- 0.5.
How do you merge the 2 records while accounting for this uncertainty?
If you keep them as separate stations, fewer headaches.
If you merge them, you fail to recognise that the older one was rejected because of a rate of change that had become too fast from spurious effects like wind change from buildings, UHI etc. When, in the period of fast change, should you start the new record? Ooops, too late, the fast change started before the new station was set up, so the combined record had a splice at a time that was wrong because it introduced spurious warming in the record and in the trend FAIL.

What is the obsession with moving stations, merging stations, adjusting data? A weather station only measures the micro-climate at that station at that point in time. Currently where I live there is 3c difference between here and about 400m down the hill. If the wind changes it could go to zero difference or even flip the other way. The point is they are 2 completely different micro-climate and no amount statistical analysis is going to be able to merge there records into a single coherent temperature record. You have 2 separate weather stations measuring different climates, they may as well be a 1000 miles apart. Comparing them for 18months is meaningless relative to the past as you have no idea of the new stations micro-climate in the past.

July 29, 2022 7:01 pm

The big picture presented as simply as I can:

96% of current weather stations are sited improperly
We have had 50+ years of always wrong predictions
of a coming climate crisis, that never shows up

Imagine 100% of current weather stations sited perfectly for the past 50 years
We would still have had 50+ years of always wrong predictions
of a coming climate crisis, that never shows up

Predictions of climate doom would still exist.

The predictions are not related to any past climate trends.
Global warming since 1975 was mild and harmless.
The predictions are for future global warming that is rapid and dangerous.

The predictions have been wrong for 50 years.
But they will continue because people believe them.

When people fear the future climate, they demand that their governments do something. That demand is the goal of climate scaremongering. Climate change propaganda has achieved the intended goal of significantly increased government control over the private sector.

“Climate change” is not about science
Always wrong wild guesses
of a coming climate crisis
are not science.

This explains why government bureaucrat scientists could not care less that 96% of weather stations are improperly sited. They were hired to predict a coming climate crisis, unrelated to past global warming, so they do what they are paid for.
Just like scientists hired by cigarette companies
were paid to claim cigarettes were safe.
Governments get the science they pay for.

Even if it was 6% my reaction would have been the same. Yet another example of why the establishment narrative is absurd. Whether it is SLR or historical temperatures or droughts or floods or oscillations or heatwaves or previous warm periods or the LIA, etc etc, there is research contradicting the IPCC. They would have had more credibility had they spent decades asking questions rather than trying to brainwash the public into believing they had all the answers.

And the climate scaremongering would ave been the same
if US weather station data were perfect or not.

But the msm did mention Iraqi weapons of mass destruction
And how Trump colluded with Russians to win in 2016.
And that Covid vaccines are perfectly safe and very effective.
And that the 2020 election was the most honest election in history.
Those were big msm headlines.

How many msm readers would care
about weather station siting when the world
is facing a disaster from climate change
and our children may have to move
to another planet to survive global warming?

I’ve lived in Michigan since the 1970s
and have enjoyed the mild global warming.
But what would I know?
I’m not a climate scientist with a supercomputer

person who has lived in the same home
since 1987, who enjoys our milder winters
