Readers may recall my investigation over the weekend of an announcement by the Danish Meteorological Institute (DMI) about a new all-time high temperature record set in Greenland that was subsequently picked up by the Capital Weather Gang at the Washington Post.
How not to measure temperature – Part 94 – Maniitsoq, Greenland all time high temperature rescinded?
Over the weekend, I had advised Jason Samenow of the WaPoCWG that he should probably issue some sort of retraction. Not getting any response to my initial email and tweet, I followed up with additional tweet yesterday and today. I’m happy to say that he responded with an update on the original article, and to his credit has written a new article on the subject:
Update, August 12, 12:15 p.m.: This record may not be legitimate and is under review. See related post: Greenland may not have recorded its highest summer temperature
What I find most interesting is this communication from DMI to Samenow:
[Samenow] “…according to a response from John Cappelen, data management specialist and senior climatologist.
Here’s Cappelen’s response, in full:”
Dear Jason,
The reading was valid….but the temperature sensor at the airport station Maniitsoq is not placed according to the WMO [World Meteorological Organization] standards…
It is generally very hard to follow the WMO standards in all details in arctic areas, but this sensor is placed so influence from the surroundings can have affected the reading in a way, so the reading maybe will have to be rejected.
Quality control procedures is ongoing like all ways, where we among other procedures used station data from another station in the area and look into the weather situation in more details.
Whether or not the temperature reading will be rejected and for that reason not included in the extreme records will be announced later.
Best regards,
John
So, the event is still under review.
The takeaway here is:
- They think station siting is an issue here
- Station siting quality seems to be a common problem in the Arctic
- The Maniitsoq station is not WMO compliant and thus likely not suitable for climate monitoring, but fine for aviation monitoring as I pointed out.
The other takeaway is that when there is a rush to judgement (and announcement) of significant new temperature records, the devil is always in the details, and reporting of such events should have appropriate caveats in place.
I don’t blame Samenow for this, he was reporting what DMI said, and one could generally assume their reporting can be taken as solid. But, as we see, that may not be the case.
In the current mindset of warmer world, it is easy to brush aside such concerns, only to find later they come back as legitimate concerns that may make the report a non-event.
It should be noted that any new temperature record is subject to review, all-time high ones, even more so. A rush to trumpet a new temperature record before it is certified doesn’t help the credibility of climate science.

Anthony,
Remember Death Valley too- you did a great article in the new temp station sited in what looks like the focus of a parabolic cliff at the end of an airless waddy. They will be out with that one like a shot when it happens.

Anthony, you found a bad high temperature record a few years ago in Hawaii but were told it would stand at least the Danes are looking into this.

Oh don’t worry. They will correct it when the time comes to lower temps in the past so as to make current temps seem higher.
“A rush to trumpet a new temperature record before it is certified doesn’t help the credibility of climate science.”
Neither does the hockey schtick, the attempted abolition of the medieval warm period or the plethora of convenient ‘adjustments’ to the temperature record, the irretrievable loss of temperature data, the inability to surrender method, and on and on….
No sir.
To the stampeding herd of sycophantic bureaucrats, MSM, climate ‘scientistas’, policy makers, carbon racketeers, banksters, Uncle Tom Cobbly ‘n all, the credibility of climate science is COMPLETELY irrelevant.
A very positive sign: The DMI acknowledged they have siting problems.
They bent over backwards to deny the Illinois record LOW temp a few winters ago, not understanding that temps can vary greatly, more quickly, when they are very low. 2 mornings in a row it hit -38. The first morning then claimed something was wrong, then “fixed” the problem. the second morning… you do the math
The Maine record low was done is a much more professional way and was verified as I believe the OK state record.
I am sensitive to this issue because a) the Altantic City record high of 106 in 1969 was a joke.. no temp within 100 miles of the airport was above 100 and a strong south wind was blowing. My father went out there and with 5 thermometers, showed there was a warm bias that would increase the warmer it got ( in other words at 0C it might be fine, but as it rose, the difference from the other thermometers rose.. A reproduction indicated that at a mean of 5 thermometers at 96, the airport reading was 106! It was likely a 10 degree error..DC was the closest station to reach 100 degrees) The second is the course I took at PSU, meteo 461 which showed how the buiding, siting and upkeep of thermometers, if not done properly almost always results in WARMER readings than what actually is occurring Since that course had labs that
kept me up all night ( it wasnt just reading the instrument, but building and calibrating) I still have the scars of what it takes to maintain a proper thermometer
The real takeaway Anthony is YOUR INFLUENCE. As others have said or intimated, if it weren’t for you & other Warmist sites & bloggers, there’s no telling how swamped we’d be in CO2 taxes, environmental restrictions, etc, etc.

“And don’t those temperatures wind up going into at least one or more of the official global temperature data sets?”
Not only that but GISS extrapolates the arctic ones over 1600km. I wonder if much of the “red hot” colour-coding in the arctic arises from this?

Now that the “record temperature” has been rescinded, will you be offering the same number of column inches to why it wasn’t a record breaker?

I wish I could go back in time and hand Leif Ericson a thermometer and have him send me its readings for the summer of AD 1000 when he lived in Greenland. It would be nice to have some relevant temperature readings to beat in this modern day….

Apparently there are more people who discovered the problems with what she writes …
There are a couple of obvious things mentioned in one of the comments and strange enough the comment is not deleted, which usually is a tradition at pro-AGW sites …
So it’s a valid reading…….of course. The reading is spot on for the local airport temperature but what does it tell me about the surrounding areas? Jason should do a read up on albedo. I understand that the airport is rather dark in color. Jason, start here:
PS, don’t any warmist tell me that it is not soot at the airport. I KNOW. My comment concerns albedo.
A completely bogus practice, unless the other station is VERY close to the first.
I live in Oak Harbor, WA and work in Mt Vernon, WA, a straight-line distance of 10-12 miles. On a sunny day, the summer temps between the two locations can differ by as much as 15f at the same time of day. I live it every day. Last week in Mt Vernon it was about 84f almost every day when I left work. By the time I got home it was about 70f. This is also reflected in the temperature stations used by the local news network.
You just can’t average temperatures from different locations and come up with anything meaningful.
“The reading was valid …”
If I was a pilot flying into that air strip, that’s exactly the reading I would want – not some local climatalogically valid vaue, but the actual local temperature. I want to know if there is likely to be ice on the runway or not, and don’t really care whether the same location would have ice without the runway.
So the problem here is not “bad” citing, but that there is no existing world-wide set of climate recording stations designed for that purpose. This one (and most others) was designed for a different purpose, and it performs that purpose just fine.

Conclusion, Antarctica is not warming, therefore the global warming claims are rejected.
=============
Global warming is almost exclusively a warming of the northern hemisphere polar region. Somehow this regional warming is taken to be evidence of global warming, while the cooling of Europe during the LIA is taken to be evidence of regional cooling.
It appears that all warming is global if it happens anywhere, but all cooling is regional unless it happens everywhere.
What I find interesting is the continued belief that CO2 can heat the north pole and not the south. While at the same time we are seeing the largest change in earth’s magnetic field in recorded history. Is it co-incidence that the north pole is warming while the north magnetic pole mores northward. Is it co-incidence that the south pole is not warming, while the south magnetic pole also moves northward?
Is it co-incidence that the IPCC and solar science in general makes no allowance for the solar wind influencing the earth’s climate? That the IPCC and solar science consider only solar radiation, while ignoring the effects of charged particles from the solar wind on the earth’s atmosphere?
While all the while the regional warming at the north pole is screaming. It is magnetism. It is the solar wind. This is what is driving the warming at the north pole. It cannot be CO2 because if it was it would also affect the south pole. The solar wind is not warming the south pole because the south magnetic pole is not at the south pole, it is not even located in Antarctica, and it is not moving towards the south pole.

MODERATOR – my apologies, I missed a closing blockquote in the post I just made. Would you please delete it, and post the following instead (Or just add the closing blockquote after “temperature data sets?”): Thanks so much, and sorry for the hassle.
Exactly my thought. I don’t know how far the Greenland ones wind up being extrapolated to cover other areas, but at one point seem to recall that one of the data sets extended some as far as 2500km.
The downside, of course, is that the error was a headline. The upside is that the source for the headline was willing to take another look at it.
Perhaps the pressure to tow the “consensus” AGW line is relenting as reality set in?
