Guest essay by Larry Hamlin
The Climate Intelligence Foundation (CLINTEL) has cataloged significant errors in the UN IPCC AR6 Summary for Policy Makers (SPM) and distributed this error listing and analysis to the IPCC Chair and other world leaders to inform them of these errors.
The identified errors result in the SPM failing to meet standards of objective scientific integrity and therefore misleads world leaders regarding appropriate climate policy by erroneously pointing to a “climate crisis” that does not exist in reality. The seriously flawed SPM is “inappropriately being used to justify drastic social, economic and human changes through severe mitigation, while prudent adaptation” would be much more appropriate.
The significant errors are grouped into six key areas noted in the CLINTEL report as follows:
The SPM claim that human influence alone has warmed the planet is “unequivocal” is false with this claim ignoring natural climate influences including impacts of solar variability, natural events such as ENSO, El Niño, La Niña, AMO, PDO, etc. as well as impacts from geomagnetic storms, earthquakes, tsunamis and volcanic eruptions in addition to other areas of evidence addressed in the CLINTEL report that have been systematically ignored by the IPCC as shown in the summary below.
Most significantly flawed statistical schemes (attribution to “unequivocal” based on “major advances in science of attribution” claim) have been relied upon by the IPCC to support the “unequivocal” assertion with these schemes questioned by world renowned statistics experts Dr. Ross McKitrick and Steven McIntyre. These challenges require further evaluation by the IPCC SPM climate alarmist advocates.
This highly questionable “unequivocal” assertion contaminates all SPM claims across the six key areas of review as reflected in the use again and again of the flawed terms “human caused”, ”human-induced” and “human influenced”.
A portion of the CLINTEL summary rejecting the SPM “unequivocal” claim is provided below.
The CLINTEL report provides further examination of the issues noted above related to “human influence” and then addresses the statistical errors used in the “unequivocal” attribution claim as follows:
The CLINTEL report concludes:
“Thus, the opening attribution statement in the SPM “It is unequivocal that human influence has warmed the atmosphere, ocean and land”is not scientifically robust. Additionally, the omission of any serious attempt to investigate any other explanations of climate change reflects a lack of IPCC open thinking and objectivity.”
The AR6 SPM utilizes flawed statistics to reinvent the phony “hockey stick” all over again to hide natural temperature climate variability over the last 2,000 years as identified in the CLINTEL report which notes the complete exclusion of the extensive and well established Medieval Warming Period peer reviewed proven data and studies in addition to ignoring the Minoan and Roman Warming Periods data and studies as well.
An example of one of the numerous peer reviewed temperature reconstructions that document these well-established warming periods in shown below.
Looking at what the IPCC has done with the AR6 SPM “hockey stick” brings back memories of the IPCC “Hide the decline” trick debacle back in the climate science Watergate era that exposed climate alarmist “scientist” data manipulation shenanigans (recognizing that the nature of the “tricks” used in the hide the decline debacle is different than the statistical “tricks” used in the AR6 SPM report) as shown below.
The CLINTEL report addresses the SPM misrepresentation of climate temperature reconstruction data over the period of the last 2,000 years as shown in their summary below.
The CLINTEL report concludes:
“It is concluded that the “hockey-stick” presented in the SPM has no rigorous scientific basis and misrepresents climate variability over the last two millennia. As a corollary, it cannot be asserted that recent climate variations are “unprecedented”.
The UN IPCC AR6 SPM “disappearing” the Medieval Warming Period is such an egregiously flawed climate alarmist propaganda scheme that it deserves a much higher level of scientific scrutiny and public attention.
The Medieval Warming Period is scientifically proven beyond doubt as presented (top photo) in numerous paleoclimate surface temperature reconstructions including by Dr. Judith Curry as shown in the comparison below which clearly displays the huge manipulated distortion in temperature reconstruction data present in the IPCC SPM over the last 2,000 years (bottom photo).
Additionally in an article at JoNova a summary of a just a few of the many global-wide paleoclimate surface temperature reconstructions are provided which clearly establish the idiocy of trying to deny that the Medieval Warming Period existed as done in the IPCC AR6 SPM.
That the IPCC Medieval Warming Period denial is based on absurdly contrived and flawed statistical “tricks” by politically driven climate alarmist authors who arrogantly believe their “tricks” are superior to and trump decades of global data collected and analyzed by dozens of peer-reviewed and published studies is simply astounding as clearly demonstrated by the Medieval Period data and studies from the JoNova article shown below. This article was first written in 2019 but is entirely relevant now considering the AR6 SPM warming period deceptions.
The JoNova article then provides a summary of just a few of the massive number of peered reviewed scientific data and studies that unequivocally supports the extraordinary climate variability of the last two millennia including the Medieval Warming Period which the UN IPCC tries to “disappear” by use of flawed statistical “tricks” addressed by Dr. McKitrick and Steve McIntyre in the CLINTEL report.
The fact that the UN IPCC would undertake such a colossally underhanded and erroneously flawed scheme as denying the unequivocal scientifically established credibility of the Medieval Warming Period that drove climate variability over the last two millennia reveals their desperate attempt to justify contrived and ludicrous phony “climate crisis” propaganda claims with this action clearly supporting that the SPM fails to meet standards of “objective scientific integrity.”
Additionally, the huge global-wide preponderance of peer reviewed scientific temperature reconstruction studies unequivocally supporting the existence of the Medieval Warming Period (as well as the Minoan and Roman Warming Periods) clearly constitutes proof that the statistical schemes and “tricks” utilized by the IPCC to “disappear” this warming period must be judged as being flawed and false.
This blatant act of “disappearing” the Medieval Warming Period reveals the politically motivated lack of climate science competence and integrity of the entire UN IPCC AR6 report and process and clearly displays that the IPCC promotes the politicalization of climate alarmist propaganda as its goal even if it means falsely rejecting, distorting and manipulating well established and proven peer reviewed scientific data.
The AR6 SPM was deliberately manipulated to meet alarmist political goals that would support the COP26 efforts to falsely mandate global nations to abandon fossil fuels and embrace excessive and costly use of unreliable, nondispatchable and backup power reliant renewable energy.
Fortunately, this scheme completely failed and the developing nations (led by China and India) controlled the outcome of COP26 by refusing to meet these economically destructive, scientifically flawed and purely climate alarmist contrived demands.
The CLINTEL report next addresses the SPM misrepresentations (again note the use of the terms “human-induced” and ”human influence”) regarding extreme weather as summarized below with the CLINTEL criticisms contained in the summary further expanded upon in more detail in their report.
The CLINTEL report notes that the draft AR6 WG1 is inconsistent with the SPM claims regarding flooding noting that “there is low confidence in the human influence on the changes in high river flows on a global scale”, that ”heavier rainfall does not always lead to greater flooding” and “the number of significant trends in major-flood occurrences across North America and Europe was approximately the number expected due to chance alone” as well as “Changes over time in the occurrence of major floods were dominated by multidecadal variability rather than by long-term trends.”
The report notes that “Perhaps the best overview of weather events since the last Ice Age is given in HH Lamb’s classic “Climate, History and the Modern World”, first published in 1982, reprinted many times since then. It also documented extreme weather events in the global cooling period of the 1960s and 1970s. This book alone leaves little doubt that modern-day so-called “extreme weather” events are not at all unprecedented.”
“As a conclusion, the SPM misrepresents the detailed findings on extreme events.”
The CLINTEL report next addresses the SPM misrepresentations (again note the use of the term “human influence”) of developments in Cryosphere as summarized below.
Dr. Curry in her presentation provided data addressing the long-term behavior of Arctic higher temperatures over the last 2,000 years as shown below with even higher Arctic temperatures occurring in the Holocene Thermal Optimum period 4,000 to 8,000 years ago.
The Antarctica, Greenland and Glaciers are summarized in the CLINTEL report sections below.
“In conclusion, the claimed changes in the cryosphere are not borne out by observations.”
The CLINTEL report next addresses SPM misrepresentations (again note the use of the terms “human influence” and “human Influences”) of developments in the Oceans.
Dr. Curry in her presentation specifically addresses the flawed claim that “human influence” is the main driver of acceleration in sea level rise since 1971 as shown in her graph below.
NOAA tide gauge data continues to support the outcome “that the absolute global sea level rise is believed to be between 1.7 to 1.8 mm/yr.” as noted in their document shown below. This level of global sea level rise is consistent with the CLINTEL GMSL rise as discussed above in their report which rejects claims of sea level rising at a faster rate than in the last 3.000 years.
Media hyped claims of Maldives & Pacific-Indian Ocean Island catastrophic sea level rise are unfounded as shown below from the report.
Regarding Ocean Warming and Acidification the CLINTEL reports notes:
“In conclusion, claims concerning rising sea levels, warming and acidity are misrepresented.”
The CLINTEL report next addresses SPM misrepresentations of oversensitivity of climate models.
Concerning satellite-observed tropospheric temperature trends the CLINTEL report notes:
The CLINTEL report includes a brief comment on the importance of adaptation versus mitigation as follows:

I’ve been waiting for something like this. My understanding of the summary report for policy makers is that it is primarily a political document masquerading as a scientific document. That it is not representative of the actual IPCC report. My feeling is that the authors of the summary report need to be fully exposed and taken to the wood shed for well deserved punishment.
Groups of educated and elite policy makers once gathered together to toss virgins into volcanoes to appease angry gods who disrupted harvests by manifesting bad weather. The summary of the results of those policy makers is unclear today and largely ignored.
Groups of educated and elite policy makers once gathered together to discuss the number of angels that could dance on the head of a pin. The summary of the results of those policy makers is unclear today and largely ignored.
Groups of educated and elite policy makers once gathered together to discuss the subject of “weather cooking” performed by known witches which ruined crop yields. The summary of the results of those policy makers is unclear today and largely ignored.
Groups of educated and elite policy makers are gathered together today to discuss world plans of weather modification by geoengineering to “save the world from climate armageddon”. The summary of the results of those policy makers is unclear today but what is clear is that they are all psychic, because it has never happened before.
Why wouldn’t they deceive when it’s all they’ve ever done? AGW is the monster of big lies.
“If you tell a lie big enough and keep repeating it, people will eventually come to believe it. The lie can be maintained only for such time as the State can shield the people from the truth. It thus becomes vitally important for the State to use all of its powers to repress dissent, for the truth is the mortal enemy of the lie, and thus by extension, the truth is the greatest enemy of the State.” – Joseph Goebbels
“[I]n the big lie there is always a certain force of credibility; because the broad masses of a nation are always more easily corrupted in the deeper strata of their emotional nature than consciously or voluntarily; and thus in the primitive simplicity of their minds they more readily fall victims to the big lie than the small lie, since they themselves often tell small lies in little matters but would be ashamed to resort to large-scale falsehoods. It would never come into their heads to fabricate colossal untruths, and they would not believe that others could have the impudence to distort the truth so infamously. Even though the facts which prove this to be so may be brought clearly to their minds, they will still doubt and waver and will continue to think that there may be some other explanation. For the grossly impudent lie always leaves traces behind it, even after it has been nailed down, a fact which is known to all expert liars in this world and to all who conspire together in the art of lying.” – Adolph Hitler
60 years later the infiltration is complete, from local school boards to the military industrial complex. But it’s a house of cards built by tyrants and threatened by the winds of truth; censorship is their ONLY shield from collapse.
“For we are opposed around the world, by a monolithic and ruthless conspiracy that relies primarily on covert means for expanding its sphere of influence; on infiltration instead of invasion, on subversion instead of elections; on intimidation instead of free choice, on guerrillas by night instead of armies by day. It is a system which has conscripted vast human and material resources into the building of a tightly knit, highly efficient machine that combines military, diplomatic, intelligence, economic, scientific and political operations. Its preparations are concealed, not published; it’s mistakes are buried, not headlined; its dissenters are silenced, not praised. No expenditure is questioned, no rumor is printed, no secret is revealed. It conducts the Cold War, in short, with a war-time discipline no democracy would ever hope or wish to match.”

Manipulating humans using human psychology. That’s what Hitler and Goebbels were doing deliberately, and that’s what the leaders of our age are also doing.
I would say that the Propaganda Wing of the radical Leftists in the Western Democracies have far surpassed the propaganda abilities of the Nazis. They operate the same way, by repeating leftwing lies over and over and over again, but they have so much more reach than the Nazis ever had.
It’s amazing anyone can think straight after listening to all the lies put out by the Leftwing Media.
Happily, there are some who *can* think straight, and know BS for what it is when they hear and see it.
From the article: “The seriously flawed SPM is “inappropriately being used to justify drastic social, economic and human changes through severe mitigation, while prudent adaptation” would be much more appropriate.”
Adaption to what? A fake CO2/climate crisis? Why would we need to adapt to that?
From the article:
1. There’s no evidence humans are causing the warming of the atmosphere.
2. Clintel criticizes the IPCC for not including the Roman and Medieval warm periods in their temperature graph. But there’s no mention of the written, historic temperature record from Clintel, which is much more definitive than the Roman or Medieval warm periods.
The written, historic temperature record does not show that CO2 is a major player in warming the atmosphere. Instead, the written, historic temperature record shows it was just as warm in the Early Twentieth Century as it is today, so why doesn’t Clintel point these facts out? This is the equivalent of acceptance of the bastardization of the instrument-era temperature record by Clintel. Why would Clintel accept this blatant lie?
I would have copied and pasted Clintel’s remarks but the way the page is formatted prevents copy and paste. I think this way of formatting should not be done at WUWT. Text. Give us text. So we can copy and paste and expose the misinformation.
From the article: “The UN IPCC AR6 SPM “disappearing” the Medieval Warming Period is such an egregiously flawed climate alarmist propaganda scheme that it deserves a much higher level of scientific scrutiny and public attention.”
So why doesn’t the disappearing of the Early Twentieth Century warming by dishonest alarmists get Clintel equally exercised?
The Early Twnetieth Century warming proves the same thing the Medieval warming proves: That it was just as warm in the past as it is today, and CO2 had not added to that warmth, since we are no warmer today than then, and are actually cooler today than then.
Why is Clintel afraid to take on Phil Jones?
A good book to read about the corruption of the UN IPCC is:
