How much money has the world wasted because of some tree ring studies?
A Chinese group has looked at all the different kinds of 2,000 year long proxies in the PAGES dataset and found that history looks quite different depending on which proxy you pick. Only the tree rings show the HockeyStick shape that matches the climate models. In other proxies, temperatures have fallen for most of the last 2,000 years, especially in the Southern half of the world. And even after the recent warming, we are not yet back to the temperatures the Romans lived through.
So yet again, we see that that current temperatures are not unusual except according to tree rings, which we know are affected by rising levels of CO2. (The paper does not mention CO2 or carbon or fertilizer).
“All the evidence points out that we are still far from a complete understanding of the Common Era temperature variability at hemispheric and global scales,” says Professor Yang.”
“We show that the millennial cooling of annual mean temperatures is likely a global phenomenon.”
The world according to tree-rings is at the top, and other proxies, below:

The “hockey stick” graph as published in IPCC TAR (Figure 2-20, 2001)

Climate deniers must be punished
For newcomers: Michael Mann’s hockeystick graph was wildly different from hundreds of studies of other studies and instantly became the pet graph of the IPCC. It used the wrong proxy, the wrong tree, and the wrong type of averaging. Whole books were written on how bad it was. But when Mark Steyn called it fraudulent Mann sued.
Twelve long years after the case was launched, the six person jury decided that Mark Steyn and Rand Simberg have defamed Michael Mann, but awarded Mann one whole dollar in damages, because he hadn’t been able to prove he suffered any damage at all. Remarkably, though, the jurors felt the skeptics had been so malicious they added punitive damages too. Usually these are limited to a mere four or five times the compensatory damage, but this time it was decided Simberg should pay $1,000 and Mark Steyn $1 million. It sets a new record.
According to Law.com punitive or exemplary damages are saved for truly dreadful acts:
exemplary damages n. often called punitive damages… are damages requested and/or awarded […]
The Wheels Slowly Turn on the Shifting Sands of The Narrative
After years of saying the Little Ice Age was just a European, or Northern Hemisphere event, now apparently it was more global. It’s just that it was caused by volcanoes and white guys.
Climate crisis: what lessons can we learn from the last great cooling-off period?
Michael Marshall, The Guardian
The ‘little ice age’ of the 14th to the 19th centuries brought cold winters to Europe and unusual weather globally. Studying how humans adapted could be valuable.
The story isn’t entirely settled, but researchers are increasingly confident about the initial trigger: volcanoes.
“You have these eruptions that are happening in clusters,” says Degroot. A 2015 study used data from ice cores to identify 25 major eruptions from the past 2,500 years. Between 1200 and 1400, there were huge eruptions of the Samalas volcano in Indonesia, Quilotoa in Ecuador and El Chichón in Mexico.
But the volcanoes reasoning is a bit hand-wavy and vague, so Michael Marshall knows he needs other reasons. He considers the sun as a ball-of-pure-light for a few paragraphs, ignoring that it might have […]
“The IPCC remains addicted to hockeysticks”
In the 6th dimension of Intergovernmental Climate Propaganda, which arrived last week, the long discredited Hockeystick is not just a sidenote, it’s the very first graph the IPCC uses in their Summary for Powerful people (the ones who make policy).
As per usual, hundreds of years of warmth has been retro-extinguished. Thousands of proxies around the world all deviated from the real temperature and non-randomly in the same direction. It’s a conspiracy I tell you! Luckily the IPCC has found scientists who can correct these simultaneous errors of proxiness which mostly they do by just tossing out the results they don’t like. They ignore whole series they don’t like, delete the years that don’t work for them, and flip that data upside down if they need to. And if that’s not enough they use trees that grow larger rings when CO2 is higher.
And when they are not deleteing data, they’re using the wrong trees. No one is even pretending anymore. They’ve done it all before and no one went to jail or even lost a job.
As Steve MacIntyre tells it the PAGES2017 data set winnowed down the thousands of proxies to their […]
The Hockeystick graph rewrote history and was used to justify billions of dollars of expenditure. The people who created it were public servants dedicated to science and writing businesslike emails to each other — which is why they fought tooth and nail and with hundreds of thousands of dollars for 1,763 days to stop you reading them.
Marvel that after 1,000 years of working as thermometers, trees suddenly decalibrated in 1961 just as our national networks of adjistimongered-thermometers were established. See that red line rise…

Press Release from FME Law July 3, 2018
Arizona Appellate Court Decides Hockey Stick Emails Must Be Released Despite the University’s Appeal.
One thousand seven hundred and sixty-three days ago, on behalf of its client, the Free Market Environmental Law Clinic, PLLC (FME Law) asked the University of Arizona to hand over public records that would expose to the world the genesis of what some consider the most influential scientific publication of that decade – the Mann-Bradley-Hughes temperature reconstruction that looks like a hockey stick.
The University refused. …

This week XKCD (a popular Geek comic site) posted an epic cartoon called “A Timeline Of Earth’s Average Temperature”. It was a cutesy long godzilla hockey-stick — “scary” to the unwary.
It’s easy to make a scary historical-looking temperature graph — so easy that the artist probably didn’t even know how. (Thank Shakun, Marcott, Annan, Hadcrut and the IPCC for doing the tricky part.) First, guesstimate temperatures over last 20,000 years with anything at hand: tree-rings, ice bubbles, coral, fossilized tea leaves, whatever. Blend. Then stop the proxies, tack on thermometer data that was recorded in a different way with different errors and a very different response to faster temperature changes. Finally, launch that line into the future with unvalidated, skillless multivariate models that predict a fingerprint which 28 million weather balloons can’t find. Then take the models that didn’t work for the last twenty years, and run with the errors to the next century… Voila!
I took the 14,000 pixel cartoon and squeezed it to one shot that shows the curve that matters. See the error bars? Me neither.
(But who needs an uncertainty range when you have faith?)

The secret to a good hockey-stick […]
Looks like Scientific American has gone a bit “cosmic”: The Little Ice Age was apparently caused by black death, small pox, and slavery. The theory goes that there was a small spikey dip in CO2 levels in 1610, which was man-made. So hold your breath, that means a whole new era should start from then. This small dip of dubious causality, plus the correlation of oddly unclimatic things like slavery, seems to make the spike worthy of an impressive sciencey title, lo, a new era is born — The start of the Anthropocene.
Let’s not mention that temperatures started falling from 1400 AD. That’s 200 years before the CO2 spike down. Cause and effect are so passe in postmodern science.
Mass Deaths in Americas Start New CO2 Epoch
Scientific American:
The atmosphere recorded the mass death, slavery and war that followed 1492. The death by smallpox and warfare of an estimated 50 million native Americans—as well as the enslavement of Africans to work in the newly depopulated Americas—allowed forests to grow in former farmlands. By 1610, the growth of all those trees had sucked enough carbon dioxide out of the sky to cause a drop of at least […]
Two weeks ago on the HockeyStick Update post we discussed the miracle of how the Bristlecones used in HockeyStick graphs had finally (sort of) been updated. I marvelled that 800 year old tree rings were easier to find than ones from 2002. Now 16 years after the MBH98 “seminal” (well, popular) paper was published, Salzer et al had finally found some rare modern trees and updated the temperatures after 1980, but gosh, the tree rings didn’t proxy for the red-hot rising trends of the modern era, instead they recorded a fall. That particular hockeystick collapsed (again).
It took a while, but Greg Laden bravely dropped in here on Thursday to share a link to his post on how skeptics are misunderstanding the update with “mind numbing” arguments. My reply to him on the old thread may have gone unnoticed. So I’ll repeat it here (with slight edits). Perhaps Greg missed my reply?
Steve McIntyre has also taken Laden to task on his blog.

You’ll be shocked that after decades of studying 800 year old tree rings, someone has finally found some trees living as long ago as 2005. These rarest-of-rare tree rings have been difficult to find, compared to the rings circa Richard III. The US government may have spent $30 billion on climate research, but that apparently wasn’t enough to find trees on SheepMountain living between the vast treeless years of 1980 to now.
I’ve always thought it spoke volumes that many tree ring proxies ended in 1980, as if we’d cut down the last tree to launch the satellites in 1979. We all know that if modern tree rings showed that 1998 was warmer than 1278, the papers would have sprung forth from Nature, been copied in double page full-fear features in New Scientist, and would feature in the IPCC logo too.
Ponder that the MBH98 study was so widely cited, repeated, and used ad nauseum. It was instrumental in shaping the views of many policy makers, journalists, and members of the public, most of whom probably still believe it. The real message here is about the slowness of the scientific community to correct the problems in this paper.

Jean S revisited “Black Tuesday” with a post on Climate Audit. Even though I’ve seen these graphs before. It is still so arresting:
(Click to enlarge) Graphs from a Richard Muller presentation
People can debate the finer details of “splicing” but ultimately the second graph is deceptive. Do tree rings work, or don’t they?
When it comes to “tricks”, this is not like a trick to get the photocopier to work. It’s a trick to hide something (see that famous quote below). We don’t need a committee report to tell us whether it’s OK. It’s not science.
Climate Audit has well written a minute by minute breakdown of the emails at the time. (It was Barry Woods suggestion to add the graphs but they finish up at the end of the post.)

Matt Ridley looks at pharmaceutical research and finds problems of confirmation bias, lack of access to data, and lack of replication of results. He compares it to the hockey stick debacle which is rising in notoriety to become the new benchmark of bad science. Articles like this are especially useful, because people concerned about Tamiflu might not know anything about the HockeyStick, and might not have read an article about the climate.
In Pharmaceutical research companies may do many studies on a drug but only choose to publish the ones with results they feel better about.
The Australian
PERHAPS it should be called Tamiflugate. Yet the doubts reported by Britain’s House of Commons public accounts committee last week go well beyond the possible waste of nearly half a billion pounds ($913 million) on a flu drug that might not be much better than paracetamol. All sorts of science are contaminated with the problem of cherry-picked data.
Science at a breaking point:
The problem seems widespread. A paper in the BMJ in 2012 reported that only one fifth of clinical trials financed by the US National Institutes of Health released summaries of their results within the required one year […]
The message to the world is unequivocal:
“We are heading for somewhere that is far off from anything we have seen in the past 10,000 years – it’s through the roof. In my mind, we are heading for a different planet to the one that we have been used to,” said Jeremy Shakun of Harvard University, a co-author of the study.
Source: The-world-is-hottest-it-has-been-since-the-end-of-the-ice-age–and-the-temperatures-still-rising.
There are two factors in the new Marcott paper that are major red flags. For one, there is hardly any data in the modern end of the graph. Ponder how researchers can find 5,000 year old Foraminifera deposits, but not ones from 1940? Two: they’ve smoothed the heck out of longer periods. Marcott et al clearly say there is “…essentially no variability preserved at periods shorter than 300 years…” So if there were, say, occurrences of a warming rise exactly like the last century, this graph won’t show them.
Some of the data has a resolution as poor as “500 years” and the median is 120 years. If current temperatures were averaged over 120 years (that would be 1890 to now), the last alarming spike would blend right in with the other data. Where would the average […]
The paper might have been scientifically invalid, but it was a box-office success.
The headlines were everywhere
“1000 years of climate data confirms Australia’s warming” said the press release from University of Melbourne. It was picked up by The Guardian: “Australasia has hottest 60 years in a millennium, scientists find”; The Age and The Australian led with “Warming since 1950 ‘unprecedented’. The story was on ABC 24 and ABC news where Gergis proclaimed:” there are no other warm periods in the last 1000 years that match the warming experienced in Australasia since 1950.” It was all over the ABC including ABC Radio National, and they were “95% certain“! On ABC AM, “the last five decades years in Australia have been the warmest. ” Plus there were pages in Science Alert, Campus Daily Eco news, The Conversation, Real Climate* and Think Progress.
Blog review is where the real science gets tested
Skeptics have been looking through the paper, and three weeks after it was published a team at Climate Audit (kudos to Jean S and Nick Stokes) uncovered a problem so significant that the authors announced that this paper is “on hold”. It has been withdrawn from the American Meteorological […]
I know the Hockey Stick is old news to most blog readers here, but it’s easy to forget that the people reading the mainstream news (ie: most of the West) have no idea of the scale of the audacity involved. Up until the 1998 MBH paper came out, it was widely understood that there was a Medieval Warm Period, indeed there were hundreds of papers available at the time. The Hockey Stick Graph completely rewrote everything, yet was accepted and widely promoted without anyone so much as asking for the data… until, of course, McIntyre and McKitrick tried. It will do down in the annuals of science as one of the most egregious examples of “the not-so-scientific” method. — JoNova

Just when you think it’s too dead to kill: along comes a new paper in a top ranking statistics journal by McShane and Wyner. It’s worth taking stock. It’s a damning paper:
…we conclude unequivocally that the evidence for a ”long-handled” hockey stick (where the shaft of the hockey stick extends to the year 1000 AD) is lacking in the data.
…
But in the big scheme of things the Hockey Stick Graph was already dead.
Each one of these points is enough to cast grave doubts on the Hockey Stick. The Hockey Stick uses the wrong type of proxy – tree rings. Trees grow faster when it’s warmer, and when it’s wetter, or when the tree next-door falls down and a herd of manure-making cows move in. Almost all other types of proxies disagree (like ice cores, ocean sediments, corals, and stalagmites). Over 6000 boreholes, hundreds of studies, as well as recorded history show the world was warmer 1,000 years ago. (See here for the refs.) Even among tree rings, the Hockey Stick uses the wrong type of tree – Bristlecone pines – which appear to grow faster as CO2 […]
UPDATED Part IV: Andrew Glikson replies below.
I am impressed that Glikson replied politely, rose above any ad hominem or authority based arguments, and focused on the science and the evidence. This kind of exchange is exceedingly rare, and it made it well worth continuing. Links to Part I and II are at the end. Round 4 was copied from comments up to the post.
Depending on flawed models
by Joanne Nova
May 11, 2010
For a sentence, I almost think Dr Glikson gets it. Yes, it’s a quantitative question: Will we warm by half a measly degree or 3.5 degrees? It’s not about the direct CO2 effect (all of one paltry degree by itself), it’s the feedbacks—the humidity, clouds, lapse rates and other factors that amplify (or not) the initial minor effect of carbon.
Decades ago, the catastrophe-crowd made guesses about the feedbacks—but they were wrong. Instead of amplifying carbon’s effect two-fold (or more!) the feedbacks dampen it.
Dr Glikson has no reply. He makes no comment at all about Lindzen [1], Spencer[2] or Douglass[3] and their three peer reviewed, independent, empirical papers showing that the climate models are exaggerating the warming by […]
These maps and graphs make it clear just how brazenly unscientific the Hockey Stick is.
It’s clear that the world was warmer during medieval times. Marked on the map are study after study (all peer-reviewed) from all around the world with results of temperatures from the medieval time compared to today. These use ice cores, stalagmites, sediments, and isotopes. They agree with 6,144 boreholes around the world which found that temperatures were about 0.5°C warmer world wide.

A big news day. It appears Steve McIntyre (volunteer unpaid auditor of Big-Government-Science) has killed the Hockey Stick a second time…
The details are on the last three days of Steve McIntyre’s site Climate Audit, and summed up beautifully on Watts Up.
The sheer effrontery and gall appears to be breathtaking.
The Briffa temperature graphs have been widely cited as evidence by the IPCC, yet it appears they were based on a very carefully selected set of data, so select, that the shape of the graph would have been totally transformed if the rest of the data had been included.
Kieth Briffa used 12 samples to arrive at his version of the hockey stick and refused to provide his data for years. When McIntyre finally got hold of it, and looked at the 34 samples that Briffa left out of his graphs, a stark message was displayed. McIntyre describes it today as one of the most disquieting images he’s ever presented.

Billions for “the climate” but nothing left for audits?
It’s the most “important crisis” on Earth today, and we must rely on the science, yet it’s not quite important enough for anyone to independently double check those results. And just in case you think that the peer review process does that double checking, think again. Most papers are reviewed by only two or three colleagues who may be hoping to prove the same “theory” as the authors (so not especially keen to find holes in it), and who are unpaid and anonymous. (The saying “you get what you pay for” comes to mind. We pay to find a crisis, and we don’t pay to check the results.)
The best examples of unpaid auditing are the work of independent scientists Steve McIntyre, and Anthony Watts. The irony is that skilled workers are providing a pro bono service, normally a service to help those who can’t afford it, but in this case, to assist the largest single financial entity on the planet.
