Science scandal: What follows is an excellent overview of how the Medieval Warm Period was once again disappeared from the latest IPCC climate report.
===========================================
Who Erased The Medieval Warm Period?
Written by: a Die kalte Sonne scientist/IPCC 6th report reviewer
(Translation, edited and subheadings by P. Gosselin)
The latest UN report distorts climate history. The tracks lead to Bern, Switzerland.
In the Middle Ages, it was similarly warm in Switzerland and other parts of Central Europe as it is today. The so-called Medieval Warm Period (MWP) is scientifically well documented in the region: Between 800 and 1300 A.D., many Alpine glaciers shrank dramatically and some were even shorter than today. The tree line shifted upward. Permafrost thawed in high alpine regions that are still firmly in the grip of ice today. Warm temperatures are also clearly evidenced by tree rings, pollen, chironomid fossils, and other geological reconstruction methods.
Controversial temperature curve
It had long been assumed that the medieval warmth might be a regional, North Atlantic phenomenon. However, this has not been confirmed, because the warm phase also occurred in many other regions of the world, for example, on the Antarctic Peninsula, in the Andes, in North America, in the Arctic, in the Mediterranean, in East Africa, China and New Zealand.
Peer-reviewed: Medieval Warm Period global
Together with professional colleagues, we at Die kalte Sonne have evaluated many hundreds of case studies from around the world in recent years and published the syntheses continent by continent in peer-reviewed journals.
Three of the publications have been cited by the Intergovernmental Panel on Climate Change (IPCC) in its recently published 6th Assessment of the Climate report. The medieval warmth was then followed globally by a precipitous drop in temperature. During the Little Ice Age, 1450-1850, the climate cooled to the coldest temperature level of the entire last ten thousand years.
Taping the hockey stick back together
In the new IPCC report, one will unfortunately look for this information in vain. In it one elevates one’s own view of the climate history of the last thousand years. In the summary intended for politicians, a controversial temperature curve is prominently displayed right at the beginning, giving the impression that there were only minimal pre-industrial climate changes in the last two millennia. With the onset of industrialization around 1850, the curve then rockets upward by more than one degree. This mode of representation is also known as the “hockey stick”: The climatically supposedly uneventful pre-industrial period forms the straight shaft of the stick, and at its end, with rapid modern warming, comes the upward blade of the hockey stick. It is therefore a déjà vu, an unnecessary one. The 3rd Assessment of the Climate Report of 2001 already contained a similar field hockey stick pattern, intended to fool politicians into thinking that today’s warming was unprecedented and therefore entirely man-made.
Recent paleoclimatological research confirms Medieval Warm Period
In the last two decades, however, paleoclimatology has made great progress, and data have been diligently collected. From this, more realistic temperature developments were created, with a pronounced Medieval Warm Period and a later Little Ice Age.
All the more bitter now is the relapse into old hockey stick times. How could this happen? What were possible motivations behind the renewed distortion of climate history?
Why back to the hockey stick? PAGES 2k
The questionable new hockey stick temperature curve comes from the international paleoclimatology group PAGES 2k, whose coordinating office is based at the University of Bern in Switzerland. Climate scientist Thomas Stocker, who has contributed to IPCC reports since 1998, also teaches and conducts research at that university. In 2015, Stocker even ran for the overall IPCC chairmanship, but lost to South Korean Hoesung Lee, who just presented the 6th Working Group 1 report. Stocker co-authored the Summary for Policymakers of the IPCC’s 3rd Assessment of the Climate report in which the hockey stick played a prominent role.
Dissent among the PAGES-2k group
A good twenty years later, the resurfaced field hockey stick now comes from Stocker’s university, where he heads the Department of Climate and Environmental Physics. Just a dumb coincidence? There are many indications that the new climate curve may have been a commissioned paper for the 6th IPCC report. Five of the nineteen authors of the papers on the new hockey stick curve are from Bern.
But a significant portion of the PAGES-2k researchers could not technically support the new hockey-stick version and walked out of the group in dispute.
Proof thanks to tree rings
Meanwhile, these dissenting scientists published a competing temperature curve with clear pre-industrial climate changes. Based on tree rings, the specialists were able to prove that summer temperatures had already reached today’s levels several times in the pre-industrial past. But the work of Ulf Büntgen of the ETH Research Institute WSL and colleagues was not included in the IPCC report, although it was published in time for the editorial deadline. Interestingly, the controversial PAGES-2k curve was already included in the first draft of the 6th climate report, although the associated publication had not even formally appeared yet.
How could this be? In the second draft of the Summary for Policymakers, the curve shrank to postage-stamp size, positioned on the edge of a composite larger figure. This was the last version available for comment by the IPCC reviewers, of which a Die kalte Sonne scientist was one of the reviewers. It was all the more surprising, then, when the field hockey stick image suddenly appeared in full size in the final version.
IPCC conceals PAGES-2k controversy
The IPCC concealed from the public the fact that many experts and reviewers consider the curve to be highly problematic. On the one hand, the new hockey stick contains a whole series of outlier data, the use of which is difficult to justify. For example, PAGES-2k integrates a tree-ring dataset from the French Maritime Alps, even though the creators of the original case study explicitly advise against using it for temperature reconstructions. On the other hand, data are omitted that demonstrate strong pre-industrial natural climate variability. Detailed criticisms of this made in the review process of the report and formally published in publications were ignored by the IPCC authors.
That’s how easy it is to rewrite climate history, and hardly anyone notices. Why is this important? Pre-industrial temperature trends are highly relevant to the attribution of modern climate change to man-made factors on the one hand and natural factors on the other.
Since climate models have assigned only negligible natural climate forcings, they can only generate hockey stick patterns. Any real observed pre-industrial warm or cold phase therefore causes problems for the models because they cannot reproduce it. They are designed not to do so from the outset.
Mortally faulty model calibration
This raises uncomfortable questions about their fitness and usability for projecting the future climate. Ultimately, they are uncalibrated simulations that should not be released for future modeling at all, as long as they are still failing on past climate In other words, if a climate model provides answers to the question of what the past was like that are miles off reality, forecasting the future is likely to be similarly aberrant.
It is particularly peculiar that the climate models of the so-called CMIP6 type that were created specifically for the 6th Climate Report proved to be mostly unusable. Due to cloud modeling errors, they provided temperature histories that were far too hot. Therefore, the IPCC stated that in the current 6th report that it would place more emphasis on the historical temperature development.
Inconvenient issues
However, since this is also – as described – highly controversial, the IPCC is also now virtually flattening its spare tire. In its official press releases, the IPCC largely omits these inconvenient issues. And in most media reports, too, the public hears nothing about them.
Political tactics undermining science
Thus, scientific integrity falls by the wayside. It is only a matter of time before critical climate scientists systematically address the inconsistencies in the filtered IPCC 6th climate report. The incident reveals how political tactics are undermining the IPCC’s scientific integrity and further eroding the trust placed in the institution.

Surprising what a wad of Renminbi will buy you.
Especially if you are an incompetent, venal, Climate “Scientist:.
I would have suspected Michael Mann.
CNN interviewed Mikey Mann this morning, and he was in full doomsday/tipping point splendor. Hurricane Ida was proof of everything, case closed. What a disgusting mixture of greedy and crazy.
Many have noted that Ida struck New Orleans exactly sixteen years after Katrina. Have any mentioned that for twelve of those sixteen years (2005-2017) no major hurricanes made landfall in the U.S.? It is the longest “hurricane drought” on record and flies in the face of the doomster’s predictions of “a Katrina every year”.
Those 12 years of no major land-falling huricanes were very hard on the alarmists. They couldn’t find anything to blame on CO2, other than an occasional wildfire, heatwave or drought. It was slim pickin’s back then.
Climate scientist makes dire prediction about monster stormsMichael Mann, a lead author of the UN Climate Change report, explains the science that directly connects rising temperatures to the increased frequency and severity of major storms.
https://www.cnn.com/videos/weather/2021/09/04/michael-mann-climate-change-severe-weather-sot-nr-vpx.cnn
CNN can’t be trusted as a source of anything since what they revealed after Biden was installed in the White House. CNN admitted to 4+ years of outright lies in a premeditated plan to discredit Trump. They aren’t a “news” medium. They’re the media department of the Democratic party.
They’re the propaganda wing of the Communist party. There, fixed it for you!
A mere distinction without a difference, LOL. I’m happy with either 🙂
Democrat, not democratic, they hate democracy.
My irony font seems to have been switched off … but thanks for the correction.
It’s only democracy when they win.
They OWN the democRAT criminal party. It’s one of their created terrorist wings.
They do appear to have a close relationship with terrorist groups, don’t they? Hey … they just provided some of the worst terrorists on Earth with a made to order arsenal worth $85 billion.
Rising temperatures? IS Mikey Mann really living on this planet? Has he been to Iceland yet? It’s cold up there! People going to see the volcano are all bundled up.
And in my AO, while we had one day of “warmth” out of 18, it happened to be a cloudy day. Now it’s back to sunshine and clear skies and the “heat” of summer is gone, and I”m about to turn on the furnace a month early!
I suggest shutting off Mikey Mann’s heat for the fall and winter and find out how he likes the “warm” winters without a warm house or office.
What a dork he is. He’s really turning into a cracked record.
There’s been a pause of 7 years. Current warming 1.3C per century. Trust the science dude.
Ignoring or rewriting history occurs in more than climate studies. It’s the only way to silence dissent and accuracy when referencing a past that doesn’t agree with your narrative. That’s one definition of propaganda. Tell the “story” often and loud enough and the people will accept it.
Read George Santayana Reason in Common Sense.
Progress, far from consisting in change, depends on retentiveness. When change is absolute there remains no being to improve and no direction is set for possible improvement: and when experience is not retained, as among savages, infancy is perpetual. Those who cannot remember the past are condemned to repeat it.
As soon as I first saw the new hockey stick diagram in AR6 my memory immediately reminded me that it wasn’t showing the MWP or LIA. I am condemned to repeat that the evidence they were real is far more compelling than this attempt to stomp on history and reality.
Yes. I put a comment here on the first AR6 post noting that I thought the missing MWP would have been a leading issue. It is nice to see that AR6 hockey stick graph inspired some analyses, and these are getting posted out here for all to see and discuss.
Doug
I was not around for the Soviet purges, or China’s great famine, and was young during Pol Pot.
I have on many occasions reminded marxists, socialists, and communists about these events.
It’s not about remembering, THEY KNOW.
It is also the same with the batch of greenie climate change alarmists. THEY KNOW about pasts heatwaves, storms, floods, droughts and bushfires.
Both groups just @ur momisugly#$&ing lie. It’s that simple.
There isn’t a climate scientist alive who isn’t aware of the fraud and the utter nonsense being exposed daily on this blog. No one but the “True Believers” are taken in buy the “climate change” narrative. It has no basis in science. They’ve been lying for “The Cause” for a generation and more.
They are guilty.
We can always hope for one of those prolonged winters that start early and last long past ‘normal” seasonal change dates, along with several years of that. It might confound the “experts” like Mikey Mann because it really is difficult to ignore such things and be dismissive of them.
Michael Mann has already dismissed any future cooling. He says a decade or two of cooling would not disprove the Human-caused Global Warming hypothesis.
I believe Mann said those things right after it became apparent there was a pause in warming, and people were asking questions about the discrepancy.
Should I maybe send him my gas bill (cooking and heating) to pay? I could use the extra cash, and it seems to me he has plenty of it! 🙂
What I would really like, and sincerely hope that somehow, it happens, is for all these grants grabbers to be snowed in for about six months at a conference of some kind, so that they not only can’t get the doors open, can’t get flights home, and have to forage for food like our distant ancestors were doing.
I still haven’t asked for a DNA test to find out if I have any Heidelbergensis DNA. That would be SO cool!!! I should be doing that….
I believe the next three-month forecast for your area is cooler than normal. You probably already know that, though.
Just curious…
The top chart depicting the Holocene temperature gradient over the last 15,000 years or so would be Low Resolution.
Has anyone created a temperature gradient chart depicting what the Holocene temperature would look like in High Resolution? What would be the highest and lowest temperatures that would still fit the low resolution curve?
Most proxies that go back 15,000 years are low resolution.
It’s not honest to use low resolution in one part of a graph and high resolution in another. (Even though climate “scientists” routinely do this.)
Mark
I totally agree, the satellite era should not be strung on the end of the thermometer era as there is no clear understanding of the mechanism that controls heat distribution globally from tropical, AMO etc. Arctic amplification is the best example.
Detailed Holocene reconstructions can be found here with further links.
There isn’t a single proxy reconstruction that uses physics to derive a temperature from the proxy data.
Every single one of them showing a temperature on the ordinate axis is a scientific crock.
Are any of the IPCC reviewers issued a stamp that says –
PROPAGANDA!?
That don’t need to. It’s assumed.
All of them , except it’s spelt proposition .
Richard Muller, emeritus Professor of Physics UC Berkeley had the first comment on the Die Weltwoche article at provided URL. If you are unfamiliar with Dr Muller, his comments on the original hockey stick, and his work with BEST, there is at some factual reporting in his Wikipedia bio.
https://en.wikipedia.org/wiki/Richard_A._Muller
Here’s the Google translated version of Prof Muller’s comment from his posted German language comment:
“The IPCC has nothing to do with the climate. He is merely a vicarious agent and panic driver on behalf of the architects of a new world order. There is a climate all over the world and that is why it has been chosen as a major political factor. The IPCC has to manage this factor and publish horror reports. We shouldn’t get into the IPCC and details like the disappearance of the medieval warm period. That just distracts us from the real motives. We should focus much more on the lying climate politicians and drive them all to hell.”
The problem of course with the IPCC is it was only formed and chartered to investigate “human” causes of climate change/AGW. It was political from the outset, with a goal to produce a pre-determined conclusion, and then call the conclusions it made “science.” It is Pseudoscience to be used a epistemological club against skeptical scientists, a club that would lead to their defunding and eventual loss by attrition. Ask Judith Curry.
”
The pseudoscience got even more so with VP Al Gore using funding and hiring pressures to steer the climate science fraud train towards politcal end goals. First with corrupting pressure on Ben Santer to include attribution language to the 2nd AR, Chapter 8 (where he re-wrote in a human attribution statement without his colleagues consent,) then with the infamous Mann-fraud hockey stick in the 3rd AR, as corruptions of science to produce desired impressions and a climate narrative in the media and politicians unable or unwilling to see the deceptions at work.
The problem are the politicians that this global climate scam has enabled to gain and hold power. And now attempt to consolidate even more power against representative democracies on the road to destroying Western free-market capitalism. That is the hidden driver at work behind the climate scam, a three pronged destructive attack on the West and its power structures that gives most power to the middle class.
Muller does sound like his head is on straight. The Wikipedia article seems to be trying to present him as a CAGW advocate through sloppy syntax.
There is no need to.
He is an advocate of AGW, of the “C” part, I don’t know – as that is a term invented here….
“Call me a converted skeptic. Three years ago I identified problems in previous climate studies that, in my mind, threw doubt on the very existence of global warming. Last year, following an intensive research effort involving a dozen scientists, I concluded that global warming was real and that the prior estimates of the rate of warming were correct. I’m now going a step further: Humans are almost entirely the cause.”
https://www.wbur.org/hereandnow/2012/08/02/climate-change-skeptic
You couldn’t be more wrong about the “mostly” human cause. That is entirely an artifice created to exploit the millennium cycle of warm periods, the one we are now in.
The political climate scammers were depending on now failed “peak oil” predictions for the 2000-2010 range. Predictions that the US fracking boom for tight oil and natural gas reserves completely destroyed by moving them out at least 3-4 decades (probably more). The original environmental part of the climate scam was to stop coal mining and coal burning. That process is underway in the US, not for the climate scam, but because of cheap natural gas made abundant by fracking and associated technologies.There is now abundant recoverable oil and natural gas, no peak oil in sight, much to dismay and detriment to the climate scammers’ plans for corralling the world economic wealth in to tightly controlled centralized governments, governments answerable only to the elitist political ruling class. Not just in the US but around the world. Hence the now political imperative to stop fracking from spreading. The truth of those statements above is evident in their total resistance by the climate scammers to nuclear power.
China’s rise and economic power through use of fossil fuels has been the other fly-in-the ointment to the climate scammers’ plans. China is still rapidly expanding coal burning and so is India. Places the climate scammers can’t touch, where governments can play propagandist lip service to the climate scam, whilst the Western adversaries destroy themselves at the hands of the baizuo.
Wake up man!.
The ‘C’ part was invented here? I assume you mean WUWT.
That’s great! That means that Global Warming isn’t Catastrophic. No need to do anything, then. We can stop all the alarm, there won’t be any catastrophe.
I mean, we (‘here’) knew that anyway, but it’s great to see you admit it.
I too thought that Anthony Banton’s comment was bizarre. I haven’t heard that particular conspiracy theory before.
You really cannot imagine anything between ‘catastophic’ and ‘nothing to worry about’?
https://scienceblogs.com/stoat/2014/06/24/if-it-isnt-catastrophic-weve-got-nothing-to-worry-about-have-we
If it isn’t catastrophic, there’s no need to kill billions of people by forcing wind and solar on the world.
Another true believer who is convinced that whatever caused the warming from 1800 to 1950, stopped abruptly and CO2 took over.
This guy sounds a lot like Mueller, who goes on and on about how he too was once a skeptic.
The problem is, looking at his writings and talks, shows that he’s been a true blue believer in CAGW from the beginning.
BTW, if global warming isn’t catastrophic, then there is no reason to do anything about it. Unless you are one of those who worship in the cult of Gaia who believe that any change, no matter how trivial, that is caused by man is EVIL.
To add to that, this is exactly why the Scientific Null Hypothesis exists. It’s to stop crap scientists, scientific dufuses, snake oil salesmen, and fraudsters and other assorted criminals from claiming exactly that – that the baseline suddenly went flat around 1950.
Can’t do that Anthony, and neither can the voices in your head, and neither can the voice of authority to which appeal.
I’ve been long trying to figure out what the Null Hypothesis is for climate change. Back when it was global warming it should have been easy: it’s getting warmer; whether it was warmer or drier was largely irrelevant.
To be honest, they jumped the shark when they went to climate change as it meant it could be warmer or colder, wetter or drier, all at the same time. This nullified any notion of an Null Hypothesis – you simply cannot prove anything as everything now fits.
It has literally become as legitimate as the Flying Spaghetti Monster.
You want to take away the left’s(cemocRATS) only talking point they have left
Am willing to bet that the commentator is a different Richard Muller. It is possible for two people to have the same name.
So I guess you wrote a parallel version of The Compleat Angler?
So is there another Izaak Walton who is not catastrophist??? lol
If you’re still here mate, look up Izaak Walton Killam. IMO, he’s the best one – he funded really great Graduate and Post-Doctoral Scholarships for all the major Canadian Universities. I know this very well, and you can guess the rest for me.
I rarely agree with anything that Izaak says, but he’s probably right here. Although Richard Muller has been a critic of Mann’s hockey stick, the Richard Muller that commented on the Weltwoche article is a regular German language commenter on that German site on issues other than climate.
“The pseudoscience got even more so with VP Al Gore using funding and hiring pressures to steer the climate science fraud train towards politcal end goals. First with corrupting pressure on Ben Santer to include attribution language to the 2nd AR, Chapter 8 (where he re-wrote in a human attribution statement without his colleagues consent,)”
Great post, Joel.
Ben Santer ought to be prosecuted for scientific fraud. His lie has fooled millions of people, and has cost the world hugh sums of money because of the fear that lie has instilled in those who don’t know any better.
A dispicable lie, Mr. Santer. You, and people like you, are the problem. Liars like you, sow confusion and make things worse, not better.
And now it looks like we have more Ben Santers in this new IPCC report claiming certainty of human involvment in making the Earth’s climate worse than normal. High CONfidence, they say. What a joke!
And none of them can produce one bit of evidence to back up their claims. They are just blatantly lying to the world.
One thing we can do is to continue to call them liars. They can’t prove they are not liars because they don’t have any evidence to back up their lies.
Have they got rid of the Eemian and destroyed the Trafalgar Sq hippo in the Natural History Museum too?
“Who controls the past controls the future: who controls the present controls the past.”
— George Orwell.
It is nothing short of disgusting watching the IPCC taking is cues from Orwell’s novel.
Animal Farm is in there too.
SOS = Same old Sh*t
Although WSJ thinks the new report isn’t quite so bad as the last….
Editorially, they’ve been pretty shaky lately, on following actual, ‘real’ climate science. Perhaps this marks the start of an improvement in their policy?
“The incident reveals how political tactics are undermining the IPCC’s scientific integrity….”
Did the IPCC ever have scientific integrity?🤔
Yes, AR1. Then the scammers got to work when it didn’t deliver the narrative they were hoping for. Too many stodgy, old-school ethical scientists wrote the FAR, and Republicans still controlled the US government political structures. The USSR bogeyman had evaporated post-92, and the elitists needed a new bogeyman to scare the public. Clinton-Gore and climate scam came to the rescue.
I’m inclined to agree. I had a copy of the original draft, printed, where the executive summary had a different conclusion to the finalized version. But that’s late 1990s and it’s long gone now. Once that summary for policy makers was changed it was all down hill.
What is the ideal temp and CO2 content? Can anyone reveal these numbers?….must be some kind of secret?
I’ve been asking those questions for years and still haven’t gotten an answer.
The answers are closely held secrets, need-to-know and all…
A William Tell Overturn, perhaps?
Yeahbut…. These are all regional places, see. It kinda like just happened in one place only, except, like, a few one places. But sort of only in one region, except all over the world. Sort of. Like…
I can assure you, every part of this world that was not covered by these proxies never warmed.
How do I know this, the sacred proxies have so proclaimed.
There’s this resource showing papers covering the MWP and what they show.

People who achieve degrees in the sciences, then start altering or hiding data, are NOT scientists! They may be ideologues or religious fanatics, but a REAL scientist must maintain a skeptical outlook to truly pursue the scientific method!
In the same manner, doctors who withhold effective treatments from their patients are NOT doctors! They may be murderers or just quacks, but the last year and a half has revealed that far too many are primarily just street level dealers for the pharmaceutical companies; as supposed “climate scientists” are just shills for the UN IPCC and the rich elites behind the curtain!
“doctors who withhold effective treatments from their patients are NOT doctors!” Having suffered from serious allergies most of my life, and had my symptoms mis-diagnosed time after time, my observation is that they are all too often ignorant and unwilling to learn! I see many “warmists” the same way.
Good doctors are like good automotive mechanics. They are worth their weight in gold! However, if you get a poor mechanic, you are free to find another. In fact, you would be a fool not to do so. The same is true of doctors. If you don’t like your doctor, find another one! Unless, of course, you signed up for Obamacare.
It’s the left’s religion….period
It is still amazing to me that neolithic people crawled under European glaciers with their artifacts to die.
They must have done this as the impossibility of any climate warming exposing them under shrinking glaciers until modern humans released CO2 in the 20th century (as shown by IPCC reports) precludes any other explanation.
Yeah, that’s the ticket…. crawled under the glaciers.
Our ancestors were tough! No soy boys in that bunch.
😜
10X10^42
They were actually hunting the now extinct ice tunnelling caribou, which died out leaving no trace about 8k years ago.
Yea, they must have also carved out big caves for them trees to grow in as well. You know, the trees that left all them stumps under the glaciers.
Actually, they were logging the trees growing under those glaciers to build churches and other structures under the glaciers because that’s just how they rolled
At this point, I am loathe to accept anything put forward by the IPCC. Their past “shenanigans” regarding past temperatures make me suspicious of anything they publish… Nullus in Verba .
Creative accounting, change the figures and remove unwanted record data to produce modelling that appears to reveal a warming trend.
See hacked IPCC emails released in two batches just before the IPCC Copenhagen Conference containing exchanges between the manipulators.
And check Christopher Monckton’s audit of the modelling that also exposed the deliberate errors and omissions.
Is this a new version of Cluedo?
Dr Mann in the University of East Anglia with a hockey stick?
They couldn’t put Dr. Mann in real Cluedo, even though the pieces do have shiny heads. It would make it too easy having to guess just the room and weapon, and the weapon, as you allude to would be a cinch too. BTW, it’s called Clue over here.
Paranoia mixed with delusions of adequacy.
One paragraph from your own blog, completely over throws hundreds of years of scientific advancement.
I’m pretty sure you don’t know what “redundant” means but I could point you in a slightly better direction as far as the profitability of free markets.
Compare the wealth and prosperity of, for instance, the United States in 1750 to 2000 or any similar date one might choose.
The poorest people today have a standard of living and access to innovations even the richest people 250 years ago couldn’t even dream of.
Socialism meanwhile can barely keep its head above water and only then by piggybacking on free markets. Left to its own devices it consumes whatever wealth it inherited and eventually implodes. Every time.
Perhaps the mods delete that tripe because it’s the gruel of fools.
Rhetorical question….Can someone explain to me, again, how we know tree ring data is “reliable” prior to the invention of the thermometer in 1714, thus giving the highly accurate climate average temps quoted by the IPCC for the last couple of millennia, but somehow is unreliable in the 20th Century until present….Of course after 1714, (actually about a 100 years later) we have many highly accurate climate records and forestry records which we can assess growth rings with increased confidence….
Instead we have “the divergence problem”….
Likely tree rings are a poor proxy for temperature and a better one for rainfall….or a combination thereof.
Beyond that, trees can only record the quality of the growing season. They record nothing for any time period where they are dormant.
Agree although the radiocarbon dating of physical remains of past tree-lines at latitudes and altitudes can give clues.
Breathtaking economic ignorance.
The mods on here don’t delete stuff like that. Look at the gibberish they allow from griff and loydo. I think you’re making that up, but willing to be proved wrong.
I remember seeing that drivel posted here a week or two ago.
This post shows how Pages 2K global mean flattens the past and how the mean compares to Arctic and Antarctic temperature reconstructions over the past 2000 years. https://andymaypetrophysicist.com/2020/05/02/global-mean-temperature-flattens-the-past/
The data used by Pages 2K to calculate the global means is based on 7000 proxy records. The majority (59%) of the records are tree rings located primarily in the Northern Hemisphere. Nuekom, 2019, acknowledges that tree ring records are detrended and therefore, do not capture centennial and multi-centennial trends. Furthermore, he confirms this problem compounds backwards in time and results in underestimation of low-frequency variability especially during the first millennium of the Common Era. This would be during warm period analogs such as the MWP and RWP. The Pages 2K global mean calculations are driven by NH proxy data with an overemphasis on tree ring proxies which is the primary reason for the flattening in the past.
Christainsen et. al, 2017, has an excellent analysis and discussion on the lack of preservation of low-frequency or longer-term variability in proxy records and large-scale temperature reconstructions. He states that tree ring records have absolute annual dating control and can be cross dated with other chronologies. He confirms tree ring data has problems related to preserving the very low frequencies and longer-term trends. Additionally, he states that averaging proxies acts as a low-pass filter resulting in the signal being “flattened out,” thus preventing the true magnitude of cold and warm periods in temperature reconstructions from being captured. Both issues apply to Pages 2K global mean across the RWP and MWP and therefore, should not be directly compared to the Present centennial warming in absolute temperature terms.
Anyone who attempts to use tree rings as a temperature proxy has merely demonstrated that they know nothing about biology.
Tree rings need to be placed in perspective and should not dominate or flatten the past 2000 years. There are other proxies and historical data that document centennial temperature fluctuations like the current uptick we are currently experiencing.
Since tree rings are not temperature proxies, they should not be used in a temperature reconstruction. Period.
You make the claim that Exxon issued billions in new stock and this destroyed shareholder value. If you have actual evidence of Exxon doing this, I suggest you talk to any number of Attorneys General, as such activity is completely illegal.
I’m not up on what Exxon did or did not do financially in 1999, but what companies do is declare stock splits. For example if the do a two for one split, everyone who has one share of stock will have that one cancelled and two new shares issued in it’s place. The stock holder loses nothing in value.
Is there anything you know, that is actually true?
He also seems to be blissfully unaware, as are most jealous nitwits, that the industry has created wealth, prosperity and associated taxation for tens of thousands of individuals who make a product, or products that people want to buy.
