Peter Miesler Helps Expose USHCN Homogenization Insanity and Antarctic Illusions.

Guest essay by Jim Steele

I was recently notified, by a colleague familiar with my wildlife and restoration work in the Sierra Nevada, that a “whacko” was portraying my graph of temperature trends at Yosemite and Antarctica’s Dumont D’Durville as fraudulent. The skeptic basher had written, “A little research proved the numbers on this WUWT/Steele graph are wrong for “Yosemite.” Similarly, in an attempt to smear a segment of my IEEE presentation demonstrating the Emperor Penguins were not endangered, he sniped,Then Steele produces a homemade graph. The “real data“? I think not ! In fact, I have reason to believe it’s another one of Steele’s tricks intended to deceive the unskeptical.” Yet like a little bit of knowledge, a “little research” is a dangerous thing.

The “whacko” blogger turns out to be Peter Miesler. Anyone familiar with Miesler understands he is the most unlikely person to uncover global warming deception. Miesler is one of Anthony Watts’ blog spawn, (aka various versions of “CitizenChallenged,” many versions due to being banned from several sites for slanderous comments) and authors a small website from Durango CO called WhatsUpWithThatWatts et al., dedicated to assassinating the character of any and all skeptics. Slandering Sou is one of Miesler’s mentors and ally, and together they comprise the most rabid and dishonest of all bloggers I call the “Purveyors of Pernicious Prattle”. Miesler lacks any scientific training (and apparently lacks any scientific understanding) but is driven by politics writing, “Steele’s only intention seems to be feeding the Republican/Libertarian meme that scientists should not be trusted and that the under-educated should keep the “debate” alive, even though they don’t know or care for learning about the full spectrum of facts at hand.” (In truth my intention is to expose bad science, so we can be better advised by good science.)

Miesler’s helpful role in the climate debates is more analogous to Gollum in Lord of the Rings, whose demented obsessions accidentally turned the tide of evil. Like so many alarmists, any climate scientist who has suggested CO2 warming has been detrimental to wildlife becomes “Precious” to Miesler. Thus by presenting evidence that contradicts their precious gloom and doom, my analyses are uncritically viewed as lies sponsored by some rightwing conspiracy.

Below is the Yosemite graph under attack. I had published this graph in my book in 2013 and noted the data had been downloaded from the US Historical Network (USHCN) in 2012. I have linked to this graph in a few internet articles such as one I posted to Watts-Up-With-That, in which I debunked Camille Parmesan’s seminal paper in which she argued global warming had exterminated several populations of the Edith’s Checkerspot Butterfly. A cooling trend since the 30s in maximum temperatures for California’s montane regions was one of many pieces of evidence contradicting her global warming scenario. Nonetheless she was fast-tracked to be one of just 4 biologists on the IPCC. Since debunking Parmesan, Miesler has been obsessed with slandering me whenever he can.

I do not want to waste too much time on Miesler’s slander. But people searching for links to my work do see his tirades. He often tries to spam any serious debates at other websites. Hopefully for those similarly attacked, posting a link to this post will provide the proper framework and expose his vacuous tactics. Any risk of increasing traffic to his website will likely be more beneficial as his Gollum-esque traits have been readily apparent. For example, Dr. Paul Opler (the first invertebrate specialist for the Endangered Species Act) was included in an email discussing how to deal with “Steele”, sent by Slandering Sou and Miesler to Cook at SkepticalScience, Climate Progress, and Dr. Singer (who hoist Sou by her own petard). Opler forwarded the email to me simply saying, “You must be coming awfully close to the truth!”

clip_image004

I have referred to Yosemite’s temperature trend (in my IEEE presentation that Miesler has become obsessed with slandering) because it represented similar trends recorded in USHCN data throughout montane California, from the north at Mt Shasta in the Cascades, to Lake Tahoe (where my research was focused) and south to Death Valley. Likewise the peak warming in the 20s and 30s supported past analyses of California’s climatologist illustrating California’s rural counties had not experienced any warming that exceeded the 30s.

The poet William Shenstone wrote, “A liar begins with making falsehood appear like truth, and ends with making truth itself appear like falsehood.” Meisler is now on a mission to transform any and all skeptic truths into a falsehoods. My Yosemite graph was created purely from data downloaded from the US Historical Climate Network (USHCN) in January of 2012. Anyone (scientist or layperson), familiar with the climate data issues knows immediately that the USHCN data is a good place to compare temperature data, but Miesler’s “little research” apparently never looked in the most obvious place. So Miesler emailed the folks at the Western Regional Climate Center and their climatologist replied, “I can tell you this is not our graph nor is the data correct” and that was enough for Miesler to suggest the Yosemite graph was fraudulent. But the data is most definitely correct, if USHCN is to be trusted.

As seen in the Yosemite graph below, and downloaded from the USHCN website January 1, 2015, the trend is nearly identical to my “WUWT/Steele” graph. However because my Sierra Nevada research focused on snow pack and watershed effects, I had downloaded the USHCN data for the hydrological year, which extends from October of one year to September of the next. Thus the “year” in my graph refers to the later months (from January to September). The hydrological year slightly shifts temperature peaks and valleys seen in a January to December trend, which maybe why WRCC mistakenly thought my data was incorrect. Still the trend is very much the same, very accurate, and totally supports my assertion: Maximum temperatures have not risen since the 30s! If maximum temperatures have not exceeded that earlier peak, CO2 has not caused any regional “accumulation of heat” due to the hypothesized radiative imbalance; and Parmesan is still very wrong for suggesting global warming was extirpating butterflies.

clip_image006

The WRCC climatologists correctly noted Yosemite’s raw data was not available until 1907, but USHCN’s adjusted data always starts in the 1890s. Since those earliest temperatures are merely modeled from data presumably collected elsewhere, early temperatures are susceptible to the “modeling whim du jour” and in this case the 2015 model had created a steeper 20th century warming trend in just 2 years. I finally realized the USHCN is perpetually altering temperature trends.

I had naively assumed that after the publication of Menne (2009), that USHCN trends published after 2009 would remain fixed because data had been quality controlled for all known changes in location and instrumentation and further homogenized whenever Menne’s algorithm assumed a changing trend might not be natural. Anthony Watts, myself and many others have questioned the distortions created by homogenization and have warned about resulting warming biases. One reason for questioning Menne’s fsulting bias, is evidenced when his homogenization algorithm minimized/eliminated a well-documented 20th century cooling trend in the south eastern portion of the USA. It is ironic that while Menne’s algorithm slowly eliminates a cooling trend in the original data, simultaneously southern USA is increasingly setting more record lows and more record lows are predicted for 2015. (With freezing temperatures in Jacksonville Florida will mangroves “flee” southward contradicting a previous bogus publication that global warming was moving mangroves northward?)

As an ecologist, I never trusted homogenized USHCN data because it alters trends in local mean temperature and removes local variability in an attempt to extract a presumed “real” climate trend. As Menne writes, “although homogenization generally ensures that climate trends can be more confidently inter-compared between sites, the effect of relative biases will still be reflected in the mean temperatures of homogenized series.” But Menne’s algorithm is definitely not ensuring reliable trends! Historical trends are dramatically reversing from warming to cooling in just over 2 years. After re-reading Menne (2004) I realized that USHCN data is updated monthly and fully reprocessed and adjusted for shifts from the recent past. Although tampering with raw data in other scientific disciplines results in retractions and disciplinary actions, Menne’s brand of science boasts, “Daily adjustments are thus a promising area for future HCN development.”

The bizarre consequences of USHCN’s monthly homogenization adjustments are seen by comparing changes in Death Valley’s maximum temperature trends over the past 2 years (solid black line). Adjustments were inflicted despite the fact the data had been quality controlled and adjusted several years before. The graph below (on the right) was published in may book in 2013 and also used in a post discussing how natural weather dynamics created Death Valley’s world-record high temperature long before CO2 concentrations had any significance. The new graph on the left was downloaded on January 2, 2015. Like so many “pesky” warming-peaks of the past that defy CO2 warming theory, USHCN’s algorithm is slowly whittling away at original temperature data that otherwise would reveal a more cyclical nature to climate change.

By what possible logic, would 2 years of additional data suddenly reverse a cooling trend since the 30s and create a warming trend? I suggest we need to ask Congress for a full investigation. (Hat tip to Miesler)

clip_image008

I have also posted that the drop in Emperor Penguin numbers at the “March of the Penguin’s” colony (adjacent to the French research station Dumont D’urville and affectionately called DuDu by the locals) was likely due to researcher disturbance and there has been no evidence of “global warming.” I repeated that claim in my IEEE presentation illustrating the data downloaded from the British Arctic Survey in the graph below. But suggesting no climate doom for Emperor Penguins threatened Mielser’s “precious” beliefs and like so many alarmists, Miesler refuses to accept any documented facts that “global warming” is neither global nor harmful. All organisms act locally and the global warming statistic is a chimera of many local dynamics. Like monatne California and much of the eastern USA, there has simply been no warming since the 1930s. Yet in total denial, Mielser seeks refuge in the delusion that DuDu’s temperature trends are just a skeptic’s trick. Seeking solace Mielser queried Dr. Ainley. But like his mentor, he was hoist by his own petard. Ainley’s graphs had falsely suggested warming was killing the Emperors.

clip_image010

Not only is my graph (above) verified by data from the British Arctic Survey, but at my request, the data illustrated in my graph is the reason Dr. Ainley removed his erroneous illustration (below-left) with the fallacious rising temperature arrow (blue) from his website penguinscience.com. (Ainley has now removed that graph from a web page, but unfortunately it still persists in his educational power point.) In what will surely drive Mielser to greater Gollum-esque depravity, Ainley’s earlier publication in 2005 also reveals Ainley knew all along that winter temperatures had been declining since 1970 as seen in his published graph below on the right. Yet desperately trying to parry documented truths , Miesler then uncritically copied and pasted text and graphs to attack me, but only revealed more misrepresentations by Ainley’s “educational” website and further illustrated Mielser’s biological ignorance. (Hat tip to Miesler)

clip_image013

Mielser could not believe that DuDu’s Emperors had stopped declining once flipper banding ended. He seems to also deny satellite data that shows the number of known Emperors has doubled in recent years. Desperate for precious examples of climate doom, Miesler unwisely switched his focus to the Antarctic Peninsula on the other side of the continent. Apparently he was unaware that the declining Adelies on the peninsula are a different species, or that Adelies act very differently than Emperors. But like DuDu’s Emperors, declines in Adelie Penguins are rare local events, restricted to about 5% of Antarctica’s coastline and best explained by changes in the win direction. Furthermore the most recent survey data published in 2014 shows Adelies have thrived under climate change, increasing their abundance in Antarctica by 53% since 1993.

clip_image015

But Mielser will cut and paste anything that has a hint of his precious climate doom. He posted Ainley’s other graph suggesting a correlation with rising peninsula temperatures and Adelie penguin declines. Ignorant of Adelie penguin biology and Antarctic climate change, Mielser didn’t realize that rising western peninsula temperature happen almost completely during the winter. But Adelie Penguins winter on ice floes north of the Antarctic Circle during the winter, and Ainely agrees warming winter trends on land have no biological significance for Adelies. And as discussed in a WUWT post, Paul Homewood posted the data for 2 western peninsula research stations showing no summer warming, the time when Adelies are on land breeding.

clip_image017clip_image019

Miesler further revealed his ignorance by mindlessly copying and pasting Ainley’s text that intimated dangerous warming. “In Antarctica’s far north (Anvers Island) air temperatures have become VERY warm and ice no longer forms on the sea.” Really??!!?? Lots of sea ice forms each year around Anvers Island. Researchers report that due to the changing winds, ice in that region forms a few weeks later and retreats a few weeks earlier, but there is still plenty of ice. So I dashed another email to Ainley requesting he correct that misinformation. Otherwise devotees of gloom and doom will continue to be misled. Although my constant corrections have strained our relationship, Ainley replied “I’m making changes to the penguinscience website to correct the sea ice persistence/prevalence issue along WAP

The fallacious alarmism surrounding the Emperor Penguins “imminent extinction” can be found in one of Miesler’s link to the Center of Biological Diversity. The CBD is the environmental legal outfit that sued the USA to list the polar bear and Emperor as endangered species due CO2 warming. The CBD wrote, “The Emperor colony at Terre Adelie in East Antarctica ”featured in the Academy Award-winning French documentary, March of the Penguins” plummeted by more than 50% in the late 1970s during a warm period with little sea ice cover, when adults died en masse. Because the sea ice continues to disintegrate, and the prolonged blizzards cause ongoing chick mortality, the colony has yet to recover.” And “When sea ice breaks up before their chicks have matured and grown their waterproof feathers, chicks that are swept into the ocean are likely to die.”

Yet there is absolutely no evidence Emperors “died en masse” or were even stressed. Sea ice is expanding to record extent and satellite pictures show lots of ice along the peninsula. Furthermore there is absolutely no evidence of local ice breakouts sweeping chicks to their death. At DuDu, there is only evidence of beneficial breakouts that allowed the penguins easier access to open waters to feed. When I asked Barbraud for evidence to support his published suggestions that devastating breakouts were killing chicks, he admitted, “evidence is hard to find”. (I posted our full email exchange in the comments section here.) Because there is absolutely no evidence for drowning chicks at DuDu, I suggested to Ainley, he also remove references to such events, but he is holding strong. Ainley’s peer reviewed publications, connecting global warming to the lack of recovering Emperors at DuDu, used drowning chicks as a likely reason. So unless Barbraud publishes a retraction, Ainley is holding strong to that illusion.

Although there is no excuse for the lies, distortions and rudeness posted by Mielser or Slandering Sou, I must sympathize to a limited degree. Their delusions have been supported by bad science from the USHCN and elsewhere, and when skeptics reveal the truth, it surely drives them mad.

Mark Twain astutely recognized, “In religion and politics people’s beliefs and convictions are in almost every case gotten at second-hand, and without examination, from authorities who have not themselves examined the questions at issue but have taken them at second-hand from other.” And while Peter Miesler and Slandering Sou are iconic examples of this failing, Twain’s remarks should be a warning to us all.

But the data is most definitely correct, if USHCN is to be trusted.
No and no.
Unless you are using raw data, the microsite is (damn) clean, and TOBS is reasonably consistent.
If so, then maybe.
Trends are tricky: bad microsite exaggerates warming, but it exaggerates cooling, as well. Bad microsite is a trend amplifier, and it doesn’t matter what kind of trend it is.
But USHCN is the best surface dataset available, so far as I know. At least the metadata for the past 30+ years is pretty good.
So if it’s USHCN, it’s been surveyed and I have no doubt done up the maps and ratings for it, and the 1979-2008 trends. Let me see what I have on record.

Okay, here’s what I have on Yosemite:
— It’s a Class 2 station. Site is pretty cluttered fro a Class 2. It would be class 4, using Leroy (1999), but is a Class 2 using Leroy (2010).
— TOBS was at 7:00 to 1991, then 24:00 to 1997, then 8:00 to 2008. The 24:00 hour period is on the Tmin side, and even if it weren’t, it straddles the middle of the interval, and will therefore not affect trend. And there really isn’t a dime’s worth of difference for a 7:00 to 8:00. So that’s fine.
— Trend is ~0.100C/decade from 1979 to 2008. Higher than most other California Class 2 stations, but a lot lower than the adjusted/homogenized “official” trend. It hasn’t warmed a lot in CA since the late 1970s.
— It converted to MMTS in 1984. (“We can adjust for that” — i.e. bump up the trend very slightly.)
All in all, it’s a good site. Thumbs up.
So be sure to use unflagged raw data only on this one. (You can step-change the datapoints by +0.1C for TMAX and -0.025C for Timin to account for MMTS conversion.)

Am not sure how to interpret your “no and no” comment. I use the graph from Yosemite precisely because it is a relatively good site as you also suggest. I have no quibble with the maximum temperature trend as now presented. I also have referred to Yosemite’s maximum trend in posts because it presented a trend that was seen throughout montane California. It was Mielser who trie to suggest the Yosemite trend was a fraud because current temperatures have never exceeded the 20s and 30s peak and thus no global warming.
The more salient point is just 2 years ago Death Valley exhibited a very similar trend to Yosemite with a maximum peak in the 20s and 30s. After 2 years of monthly homogenization the trend was completely reversed.

Barry
January 8, 2015 5:36 pm

Actually, the steady rise in minimum temperatures in Yosemite and Death Valley is indicative of greenhouse gas-induced global warming — more “insulation” to prevent cooling at night. And as for all the cold records, that’s because of Arctic amplification putting the Jet Stream on a wild meandering course. Whenever you think the world might be cooling because it’s cold where you live, just take a look at the record heat in the Arctic (where all the cold air should be) – http://cci-reanalyzer.org/DailySummary/#

January 8, 2015 6:07 pm

Barry, rising minimums maybe consistent with CO2 warming but not declining maximums. Rising minimums are also consistent with more traffic and waste heat. Rising minimums were most consistent with more El Ninos from 1970s to 2000. After 2000, both the minimum temps and frequencies of El Nino decline which is quite inconsistent with rising CO2.
Some people do claim that Arctic Amplification has caused the Jet Stream to meander more than usual, but that is pure speculation. I suspect most climate scientists agree the greater meander is a function of the increased high pressure in the eastern Pacific during the current La NIna/-PDO cycle. Trenberth himself suggests the meander is increased by those cooler Pacific Ocean temperatures. Furthermore the topography of the western USA has always caused the jet stream to meander northward and then flow southward on the eastern side of the Rocky Mountains . There are two typical winter storm systems that occur centered around Colorado and Alberta Canada because the Rockies create that jet stream meander which causes upper level divergence and enhanced cyclonic activity. I suggest you read about the formation of Alberta Clippers and Great Plains winter storms. The Alberta Clipper headed right now towards the Great Lakes is a pattern that has occurred for at least 100 years.
Finally you are right to point out that global warming average is driven by warmer temperatures in the Arctic. But that is due to heat ventilating from the Arctic Ocean – not heat accumulating. So not only is it colder than usual throughout 90% of the USA, the Arctic Ocean is also cooling as illustrated by Wunsch 2014

jim Steele,

… rising minimums maybe consistent with CO2 warming but not declining maximums.

Oh? By what physical mechanisms?

Rising minimums are also consistent with more traffic and waste heat.

In a microclimate setting I agree. However, by what physics would I not also see maximums rising at a similar rate if waste heat were the primary driver? All else being equal that is. Which it never is, but it keeps the discussion of the physics from going off on too many tangents.

Brandon ask “However, by what physics would I not also see maximums rising at a similar rate if waste heat were the primary driver”
During the winter and at night when the rising trends have predominated, there is an inversion layer that traps a thin layer of waste heat and that thin layer is more easily heated by surfaces like asphalt. During the day when insolation breaks that inversion layer, surface layer is more representative a well mixed column of air. In most of east Antarctica where there is a near permanent inversion layer and very little waste heat we do no see a rising temperature trend. To be clear, I do not suggest this mechanism is the only one operating to explain the myriad of microclimates.

jim Steele,

I absolutely agree with that. I personally don’t look at a temperature time series from any one single station and say, “That’s (not) compatible with AGW theory”. In the case of this one Yosemite station it’s seductively close: the annual average daily mins are rising steadily. Same calc for daily max is dead flat. So the strongest statement I’d make is that it’s not inconsistent with AGW. By my eyes, saying any more than that requires some pretty heavy duty analysis. By default I’m skeptical of being able to do such a thing.

Barry,
Yes, your friends’ scary graphic–the big dark red blob at the North Pole–is scary, scary, scary!
The Arctic must be burning up, with all that red ink spilled all over it! That big hot spot is pushing all the Arctic air into Florida! Nasty CO2!
Oh, wait. Could this be an attempt to misinform? Is the Arctic really red-hot? Let’s look at the legend. This is showing “temperature anomalies.” That is the difference between today’s temperature and some “normal value.”
The shade of red in the Arctic hot spot means that today’s temperature is 35 degrees F “hotter” than that normal average.
Wow! That’s really hot!
But wait, let’s click to see today’s temperature in that RED-HOT-burning-spot-that’s-forcing-all-the-Arctic-cold-to-Florida.
Oh, well, that spot’s temperature is actually MINUS 20F to MINUS 40F.
So, the “RED HOT” spot (-20F) that’s forcing Arctic air into St Louis is 35 degrees F “hotter” than it’s “normal” temperature of minus 55F?
If that’s the best you’ve got, you may want to work on some more scary graphics!

I replied to Steve Mosher recently about problems with BEST. I can’t seem to access it any more
Anyway, I pointed out that Warburton in WA, Australia has a very poor temperature record, its only neighbour is 200 km away (Giles) and the QC wasn’t correct (no months with 10 days or more missing was not even close). A break point was still identified and the inhomogeneity corrected to show more warming. Such a correction for a remote station has a large effect on the average for Australia.
After hitting send, I noticed something more important. The raw data for Warburton was the raw data for Giles. Their algorithm found an inhomogeneity in data from differences with its neighbor which was the same data.
Now I am utterly convinced that the homogenization is coded to increase the warming trend.

Trafamadore says ” Do you know who funded the BEST study? Why oh why of all people would they “increase the warming trend”?”
Unless there are obvious misleading sins of omission, the issue is only obscured when we venture into “who done it and why “. The issue with data homogenization is about the statistical slicing and splicing of data that represents a myriad of natural and contradictory microclimate responses. The resulting “assembling process” gets biased by “regional expectations” that are created by a majority wins method that amplifies a assumed trend. As weather stations are increasingly affected by population effects, the more resulting curve fits what we witness from urbanization, and speculate for CO2. Again that’s why tree ring data diverges from instrumental during the baby boom era. BEST used even more fragments from more lower quality stations and less constrained due to smaller fragments that do not show the local long term trend and are more susceptible to such assembling bias. There is also a lack of incorporating natural cycles into “regional expectations. http://landscapesandcycles.net/why-unwarranted-temperature-adjustments-.html

Robert, I wonder how many other stations in Australia suffer the same “problem”? As indicated by comments in the “Harry Read Me.Txt” file that came out during Climate Gate, the Australian record is shonky at best.

Indeed as Anthony reported in Australian scientist calls for ‘heads to roll’ over adjusted temperature data http://wattsupwiththat.com/2014/08/26/australian-scientist-calls-for-heads-to-roll-over-adjusted-temperature-data/

Speaking of USHCN.
I thought that USHCN and USCRN were very different systems. using totally different climate stations.
How can it be that on this page…(link below) they match so closely ?
Thanks for any explanations.

It is not just in Yellowstone where temperatures of the 1930’s have not been exceeded. Dr. Keen put together bar graphs illustrating the point.

Thanks Don B, Dr. Keen’s graphs and analyses are well worth viewing by all. Meehl and NCAR skewed the sense of growing ration maximum temperatures to minimum temperatures by starting in 1950. From 1950 -1970s there was a trend towards more minimum record as would be expected during the negative PDO. But Meehl’s work doesnt show the 20s-30s that were known for records highs. It seems now the course is cycling again towards an increasing number of record lows relative to highs.

Thanks, Dr. Steele. A very interesting article.
Data homogenization, of course distorts the data, that’s its purpose, to reduce the differences. Just keep raw data separately and use homogenized data for statistical purposes.

Is original (not tampered with ) data available ??? if so where from ??
WUWT should be hosting unimpeachable original / historical data.
…..or have they redacted/adjusted/destroyed every thing already.
