The Marcott gong show – before in the unquestioning press and after the blogosphere review as told by Ross McKitrick

Just last month, these were the claims:

We’re screwed: 11,000 years’ worth of ­climate data prove it.  It’s among the most compelling bits of proof out there that human beings are behind global warming, and as such has become a target on Mann’s back for climate denialists looking to draw a bead on scientists. — The Atlantic, March 9th

Global Temperatures Highest in 4,000 Years The modern rise that has recreated the temperatures of 5,000 years ago is occurring at an exceedingly rapid clip on a geological time scale, appearing in graphs in the new paper as a sharp vertical spike. — Justin Gillis, New York Times, March 7th

Study: Recent heat spike unlike anything in 11,000 years  “Rapid” head spike unlike anything in 11,000 years. Research released Thursday in the journal Science uses fossils of tiny marine organisms to reconstruct global temperatures …. It shows how the globe for several thousands of years was cooling until an unprecedented reversal in the 20th century. — Seth Borenstein, The Associated Press, March 7th

True face of climate’s hockey stick graph revealed The rate of warming in the last 150 years is unlike anything that happened in at least 11,000 years, says Michael Mann of the Pennsylvania State University in University Park, who was not involved in Marcott’s study. — Michael Marshall, New Scientist magazine, March 7th

Now, Ross McKitrick, building on the work of Steve McIntyre and others in the blogosphere, shows how easily these media outlets were duped into believing this study was the end-all for proof of man-made climate change.

We’re not screwed?

11,000-year study’s 20th-century claim is groundless

On March 8, a paper appeared in the prestigious journal Science under the title A reconstruction of regional and global temperature for the past 11,300 years. Temperature reconstructions are nothing new, but papers claiming to be able to go back so far in time are rare, especially ones that promise global and regional coverage.

The new study, by Shaun Marcott, Jeremy Shakun, Peter Clark and Alan Mix, was based on an analysis of 73 long-term proxies, and offered a few interesting results: one familiar (and unremarkable), one odd but probably unimportant, and one new and stunning. The latter was an apparent discovery that 20th-century warming was a wild departure from anything seen in over 11,000 years. News of this finding flew around the world and the authors suddenly became the latest in a long line of celebrity climate scientists.

The trouble is, as they quietly admitted over the weekend, their new and stunning claim is groundless. The real story is only just emerging, and it isn’t pretty.

news flash for anyone who can try to run down estimates of insolation over the period of the Marcott et al. (2013) study!
Posted at CA, and I looked at the linked reference, it definitely only shows years 1500 – 2000 in Figure 4, so there may be some mystery about where the claim for 11,500 years of decreasing insolation comes from, is it accurate claim but simply wrong reference given, etc. Or what is going on and what does it mean for the science of the Marcott study?
seriously mistaken reference and claim about insolation over 11,500 years
[emphasis added]

Nicolas Nierenberg Posted Apr 2, 2013 at 12:23 AM
Nick, so this is pretty funny to me. They reference Huang 2004 as their source for decreasing insolation over an 11,500 year period to the present. I found the paper from S Huang 2004 GRL. It only covers 1500 to the present and claims increasing temperatures and insolation during that period. See figure 4.
This has all the correct page numbers etc. I have no idea how this could be a reference for an 11,500 year period.

“Rapid” head spike unlike anything in 11,000 years.
An egregious example of cherry picking by starting just after the end of the Younger Dryas, when temperatures warmed perhaps 10 times faster than the late 20th century over a similar period.

How do we stop this Grab-a-Headline-with-Lies trick? I suppose we can’t, but people are waking up to the lies anyway. I tell you, it’s going to get violent unless these fraudsters are pulled into line. The alarmists are making it ever more clear that they are coniving manipulators, not honest scientists making a mistake. Mistakes, people can forgive. Continuing and deliberate misconduct, they will not – especially when lives and money are on the line. Their crimes are against each and every one of us.

Supposedly, Marcott’s thesis is OK, lacking the hockey stick figure. But I’m wondering what sort of employment this newly minted PhD will be able to get after this episode. Oh! That’s right. There’s a position at NASA opening up soon.

April 2, 2013 12:05 am

Excellent account. I like the way he discusses the missing Medieval Warming as perhaps a consequence of low res and smoothing in the proxy recon. However, I also see internal contradiction in using Mann08 proxy-instrument composite alignment for their argument because the 1950 Marcott uptick climbs out of the Mann uncertainty and visa versa. So they can’t have it both ways by claiming alignment and high res by Mann08 and then contradict it where it matters, ie when the uptick starts. There is a prima facie contradiction in the comparison of change rates — even if by an external comparison with Mann08 (as now seems to be the claim) a contradiction that should have been picked up in peer review.

Seems with the spike now gone and warming at a standstill, we have a definite trend of cooling going on for the past 5000 years or so from the Marcott paper. Does that make the science community concerned about cooling, and less about the warming. You would think the paper would be embracing the warming they think we are causing, not condemning it.

Would it now be worth having an auditing process for top journals. In all other branches of life which claim authority to advise policy makers you get this (in most branches of finance and education).
Things seem to have got so bad that peer review – possibly because of the demands on reviewers – has lost its value.

I don’t know what happened to the guy. I think, assuming he’s young, he was influenced by others with the promise of fame and fortune to play loose with the data. It does raise questions about his integrity though and the usefulness of peer review.
Normally, you try to assess the situation and give the guy the benefit of the doubt (we may have all failed the same test); he is probably young – and foolish – and may have been swayed by others so I hope his life isn’t ruined by this. But still, I don’t think these mount to mitigating circumstances. His paper could’ve been used to push policies that will hurt the poorest in our society and for that reason folly shouldn’t let him off the hook. If he comes clean then may be he deserves a second chance but I think he does need to come clean.

Don’t laugh… That’s exactly what they will do. They claimed global cooling in the early 70s so why not now? A recent paper by them that WUWT addresses just last week is claiming coal soot is mitigating the warming, shifting of gears have started already, they ‘ll just flip the hockey stick over so the blade points down.

I grew up in a wealthy town where people, and especially the wives, were quite smart but knew nothing about engines, and the local auto mechanic took advantage. He would replace things that didn’t need replacing, (if he really replaced them at all.) For example he might replace a car’s ball joints after 2000 miles.
Then my mother took an auto mechanics course, (creating quite a stir as she was a prim and proper and tweedy lady among grimy guys.) Soon the local auto mechanic hated her, because she was advising all the other Moms that it was unnecessary to replace ball joints every 2000 miles. He was never actually arrested, but when he lost a lot of business he had to shape up his act.
Climate Scientists remind me of that auto mechanic. They spoke a lot of gobbledygook thinking no one had the brains to double check. Now they are losing business.
When I look through the Climategate emails, I honestly feel the Climate Scientists were even fooling each other. When one questions the other, the other replies with a bunch of gobbledygook, and the first is afraid of looking ignorant, and doesn’t dare ask, “What the heck are you going on about?”
The media has no clue about what they are going on about either, but they should have asked and probed. People like Ross McKitrick simply asked the questions which reporters should have asked, with enough knowledge to see when the complexity was truly science, and when it was mere gobbledygook and a sham.

I think that you are correct as they did this when the global cooling scare of the 70s seamlessly switched to the global warming scare. However, they are now a lot more visible, the internet does not allow things to be lost or deleted as easily as was the case in the 70s and 80s, and thanks to political funding there has been an explosion of papers all towing the political line. Hansen et al have been trying to back out – the latest meme being warming causes cooling, now the Chinese are to blame and soot has suddenly changed from being a huge positive forcing to a negative.. etc., but from the negative comments to the faithful MSM articles, it does not appear to be working and I don’t think that the population is as ready to believe as before. It will also be a difficult sell to some of the AGW apostates in Universities who are suddenly asked to volte face and start teaching the opposite to their hard fought ideas. The cognitive dissonance should cause a lot of thought.

“How do we stop this Grab-a-Headline-with-Lies trick? I suppose we can’t, but people are waking up to the lies anyway.”
It’s basically a multi-headed Pravda run by the Bilderbergers and the CFR. Murdoch for instance is a CFR member. The editor of the German Die Zeit, for instance, is a Bilderberger. So no, we won’t stop that. Liberal foundations like The Ford Foundation give cash to outlets like WaPo to stop them from going bust, calling it an award for outstanding journalism.
All channels of the traditional media are occupied by them. Well I didn’t find a link to the Daily Mail for the moment, doesn’t mean there isn’t one.
They will carefully control message AND counter-message to arrive at the synthesis they target. One could call it a pretense of haggling or a dialectic.
Blogs are not exempt; but must censor to play their role in the dialectic. Komment Macht Frei and SkepticalScience come to mind.

Good to get more of this counter-alarmist stuff in print and a good job R.M. You of course mention the reason for the incorrect graft of the uptick, but I think you have to treat your audience as a high school class – the Marcott et al supporters keep saying, yeah, whatever, but the instrumental record tells us there is a real uptick anyway. This is the straw being clung to. I would suggest mentioning that the only way to add on the instrumental record as roughly apples to apples is to average the 150 years of data- the uptick, of course, disappears. One major thing that has been largely lost in all the flurry (I see a few commenters picking up on it), is that, if the proxies have any legitimacy, the thesis graph is the darkest and scariest thing to appear in climate science! I’d say we are screwed if it is correct in the gross.The hockey team saw this horror of sliding into the next ice age and they pressured this poor fellow Marcott to cook an uptick. They even swallowed all the warm periods that they have been trying to erase in their desperation to try to alter this very unsettling graph of doom.

Gary Pearse
April 2, 2013 4:51 am

I should add, I would like to see a post, by someone in the proxy field to deal with this. If there is support for this in the many proxies this would be the biggest finding so far in climate science, maybe in science itself if we are considering the future of the human and other species. One look at that graph tells me that we are helpless to roll back mother nature as easily as all the cream-puff geoengineering types think.

Same in my town. I know a lot about automobiles and I see a lot of scamming. They love to replace brake rotors around here. Why? Because it’s the simplest job to do while the car is on the lift for inspection, it cost less than $20 a wheel and they can charge $250, and they can scare the owner into all sorts of “safety” concerns if you don’t replace them. 99% if the time it’s total rubbish.
In the book “Freakanomics” they have similar events which are ascribed to the concept of “information assymetry”. It’s essentially the power someone holds over others when there isn’t a balance in knowledge about the subject, like the true state of the brakes, or the value of an object for sale, or what the climate data really says about the climate system.

They are either idiots or biased and the reviewers have no common sense to recognize the disconnect! And why did it take skeptics to find that Marcott’s PhD thesis findings were vastly different? The hypocrisy and hubris abound! Severe penalties are well deserved to all involved in producing, reviewing and publishing this paper, maybe even the withdrawal of Marcott’s PhD.

No, I think that the public will instead be baying for blood. Should cAGW fall down, the MSM will review the effect and costs of policies that were undertaken with a view to mitigation. It will become clear that we have locked ourselves into energy prices at least some 30% higher than they need be, we have lost much industry and lost a lot of jobs. If on top of this we have to endure energy insecurity until new conventional power generators can be built, the public will not be in the mood to cut the greens some slack let alone to go with them on their next suicide mission.

The general public needs to see how the CAGW crowd operates & this shines a light on it like few other articles do.

Even if elements of the public are, the MSM will not give them any publicity. Blogs that report about such an unrest will be smeared by psychologists/sociologists as being run by the insane, as has already happened.
If the public manages to see through the propaganda fog in larger numbers, the repressive measures might get more extreme. Alternatively, if the leaders of the regime are chicken, like e.g. social democrats are, they will retreat and the meme will collapse.

Yes indeed, this is a great read and a cogent summary of the takedown of Marcott et al. Perhaps for legal reasons, Ross chose to call the deliberate re-dating of the core tops “arbitrary”, when clearly nothing could be further from the truth. That is to say, why bother re-dating without a specific purpose in mind. Furthermore, if there was a valid reason for re-dating specific samples, an explanation should have been annotated in the original paper.
One can almost picture Marcott and the team begging those responsible for originally dating the samples in question for a viable cover story. Methinks this is why it took so long for Marcott et al to post their lame FAQ/ semi-retraction. I wonder if Steve or anyone else has reached out to said individuals for a statement?

People like Susan Anderson (who she?) have no interest in going to CA (or coming here) and actually reading the detailed analyses of Marcott et al’ s fudging of the data. Instead, they keep citing and posting links to all the heavily censored alarmist blogs; sadly their appeals to authority and their belittling of people like Steve Mc do not fall on deaf ears.
The title of Revkin’s piece should be amended to “Scientists CREATE an Abrupt Warm Jog After a Very Long Cooling”. But there is more alarmist noise on the thread, than sensible presentation of the mistakes in the paper.

Shaun Marcott is a name that has now appeared in news outlets around the world. The majority of people seeing that name will never know that his ‘science’ is really a deception. They will think he is a very smart young man adding more proof to a settled science!

In some of the blogs there seems to be a misconception that Marcott et al. somehow “spliced” modern thermometer data onto their reconstruction and that the resulting sharp uptick, while misrepresenting the temporal resolution of their reconstruction, is a valid comparison.
Trouble is, that’s not what they did. Their reconstruction is a compilation of many Monte Carlo “realizations” of the actual proxy series. The Monte Carlo realizations created the uptick out of thin air, with no help from the modern instrumental record. The “blade” of the hockey stick is purely an artifact of the reconstruction statistics. People who try to claim that it’s just comparing the thermometer record to the paleo reconstruction are missing the point.

I would think that the fault lies with the universities that allow those teaching climate science to ignore valid scientific points made by qualified skeptics. You cannot blame the younger climate scientists for being alarmists when they paid good money to be indoctrinated into the CAGW cause. They seem to have been taught a religion posing as a science as well as the true science involved.
Without some sort of potential punitive measures there is no reason any school’s administration will care what is being taught. Perhaps Congress should threaten to prevent taxpayer backed student loans from being used at any university that can be shown to have suppressed or blatantly ignored evidence suggesting they are teaching pure conjecture as fact. I’m not saying something that is conjecture should not be taught, only that it should be made clear to the student that it is not fact and that the student should be both alert and open to any contradictory evidence, as that is what any true scientist should do.

Presumably some got their reference notes mixed up, since the paper referenced does not remotely support the claim, but what is the correct reference?

How did this get past peer review and when will the retraction occur?

I suspect that Marcott got some mentoring for this paper by an established climate scientist. Something along the lines of:
“Son, this thesis of yours, it’s not what we look for in the published literature. If you expect to get published, you’ve got to sex it up. You’ve got to show that it’s worse than we thought. Find a way to spike it up at the end. Mike’s got all sorts if cleaver ways to do this kind of thing. Talk to him. Learn the trade. He’s the best in the business. If you’re going to have a career in climate science you need to learn one thing: serve only what the dogs are eating.”

You correct, Tom (toml says: April 2, 2013 at 8:14 am),
But now that they (and their supporters) have admitted that the uptick is bogus (or ‘not robust’) they are defending including it because it “confirms the instrument record”. Basically, they are trying to have it both ways now that they have been caught out including a statistical artefact.
Furthermore, the uptick is probably more related not to a few Monte Carlo runs, but – as Steve McIntyre has detailed – some seriously dodgy changing of the end points of a couple of their proxies. There has been no response to this in the FAQ the authors have posted and this is most damming point in regard to their actions in writing the paper, even though the post-publication emphasis on the uptick (which they had not placed emphasis on in the paper) is also highly suspect.
Steve is very careful not to attribute motive to the authors of this paper, but it is getting harder and harder to think this is simple scientific error, especially in the way they are obfuscating in their defence.

I searched the BBC news site for recent entries for “Marcott”:
“Sorry, there are no results for ‘marcott’ in the category ‘News’.”
So I tried CNN. Their latest report is the original headline of the now-retracted hockey stick:
“Global warming is epic, long-term study says Updated March 8, 2013
Global warming has propelled Earth’s climate from one of its coldest decades since the last ice age to one of its hottest — in just one century.

How about Al Jazeera?
“Your search – marcott – did not match any documents. No pages were found containing “marcott”.”
The NBC, like CNN, still have as their latest word on Marcott the full lurid original misinformation:
“Warming fastest since dawn of civilization, study shows – Science
Updated 9:07 a.m. ET, Mon., April. 1, 2013
Overall, Marcott and colleagues note Thursday in the journal Science, the planet today is warmer than it has been for about 75 percent of the Holocene.

How about Fox news – at least they should be expected to report the discovery of data manipulation and the Marcott et al retraction?
Did you mean: “marco” ?
Your Search for marcott did not return any results.”

Well its nice to see Fox being sensitive to the possiblity that I might be Mexican. But nothing at all – even from them – about the Marcott retraction.
This is what is so sinister and dangerous about the media. Marcott et al have won and they are laughing. The initial knee-jerk predjudice-driven sensational report of the study – “climate now warmer than 75% of the Holocene, climate-change skepticism demolished” was read by millions and this will never be undone. No amount of retraction will change that fact. AGW activism worldwide has received an irreversible boost. The exposed invalidity of the study and even the marcott retraction will remain unknown to most of the public. This is the modern mass media at its politically twisted worst.

Now, Ross McKitrick, building on the work of Steve McIntyre and others in the blogosphere, shows how easily these media outlets were duped into believing this study was the end-all for proof of man-made climate change.
They weren’t duped, they were complicit in the fraud and deceit. Any of them that were duped are dumb as a bag of hammers. Deborah Feyerick of CNN falls into that category. I’m surprised she has enough brains to remember to breathe. http://www.foxnews.com/science/2013/02/11/cnn-anchor-blames-asteroid-on-global-warming/

In some of the blogs there seems to be a misconception that Marcott et al. somehow “spliced” modern thermometer data onto their reconstruction and that the resulting sharp uptick, while misrepresenting the temporal resolution of their reconstruction, is a valid comparison.
Trouble is, that’s not what they did. Their reconstruction is a compilation of many Monte Carlo “realizations” of the actual proxy series. The Monte Carlo realizations created the uptick out of thin air, with no help from the modern instrumental record. The “blade” of the hockey stick is purely an artifact of the reconstruction statistics. People who try to claim that it’s just comparing the thermometer record to the paleo reconstruction are missing the point.
==============================================
I think you’re being too charitable. I think, but can’t prove, that they intentionally manipulated proxies to show the uptick. Given they had very few proxies to play with and that they had no misgivings about moving them up and down the timeline, it wouldn’t have been very hard to do.

How difficult would it be for experts to perform an end-to-end parallel implementation of the Marcott et al reconstruction, doing so according to Marcott et al’s nominally stated methods, but instead using data which has not been arbitrarily modified and which is directly traceable back to the original data sources?

Phlogiston…ABSOLUTELY spot on.
What I was indicating earlier (and surely others before me had in mind).
I do think very many commenters here assume that simply proving a thing wrong will change perceptions. It wont. it would be good to see sceptics wake up to this reality: culture and policy is not determined bY realities but perceptions.

Wow, this is what should be called the marcottisation of a diagram.
The procedure is simple and should be added in the handbook of the small climastrologist: one takes a diagram that looks like it looks and through marcottisation one may change it to look like you want it to.
The marcottisation process works through redating the various proxies inside for the period of your interest. One can take any spaghetti graph and redating some component parts inside it, cutting off some inconvenient values obtain the graph of your desire from their average.

Was already done by several in the search of how the hockey stick was achieved – you can see here some examples:

This is what the data without being changed shows.

Thanks, Steve McIntyre, for your scrupulous attention to details. Thanks Ross McKitrick, for your clear voice. Thanks, both, for bringing the truth to light.

There is probably no hope until we literally freeze over and people notice there ain’t no warming. The Steig et al paper was debunked by SM and others showing that they artificially spread the heat from one point of the Peninsula to the whole of Antarctica if I recall correctly. The paper has not been withdrawn or retracted. I would not be surprised that the owners of the journals like Nature and Science really don’t care anymore about the science as long as the journal sells. Basically like a newspaper does with sensational stories. The fact is their income is going to keep drying up if they keep this up because no one serious will be able to believe any of the work that is published on their journals.In other words the “Name” or “prestige” of these journals is being eroded by this tomfoolery

Climate Scientists remind me of that auto mechanic. They spoke a lot of gobbledygook thinking no one had the brains to double check. Now they are losing business.
When I look through the Climategate emails, I honestly feel the Climate Scientists were even fooling each other. When one questions the other, the other replies with a bunch of gobbledygook, and the first is afraid of looking ignorant, and doesn’t dare ask, “What the heck are you going on about?”

1) They don’t need to get away with the lies, they just need to get away with it for a little while. Headline page A1, correction page A23. It’s not science, it’s propaganda.
2) I *already* view scientists like used car salesmen. Suspect until proven. It kind of boggles me that scientists in general (of all people) defend the club first and correct the problem never. Scientists need to start policing their profession on a volunteer basis, it’s pretty clear no one else is going to do it. I know that scientists claim that’s what they do, but step back and look. It’s really, really not what you do.

What a well written review by Dr. McKitrick. I think it is time to start rolling past the circled wagons. I believe the media is starting to come around. With this nonsense, corrections from every publication who published that graph should be demanded.
I call on all WUWT readers to demand retractions/corrections from any publication that put that graph in their content.
I feel sorry for Marcott. Poor bloke unknowingly fell on his sword for the team and will never work again if we regain control of grants to study real science.

What’s the story here? ‘Before’ seems to be in the real world, in national media – often under Science/Technology sections. ‘After’ refers to an online Opinion piece in a Canadian financial outlet. Result? No change. Hardly surprising when you compare the reach of real-world science to that of provincial opinion, but it’s interesting how much the need to believe can lead to the creation of a bubble-world ‘reality’.

My God people. The scariest part of all this is that Climate Change is being taught as FACT at my children’s elementary school here in Arizona – AND, the school is REQUIRED to teach it! Try undoing that disaster each and every night around the dinner table to confused 10 and 11 year olds. Those of us who are truly informed about the issue can sit around and discuss the absurd lack of data credibility all we want on forums…meanwhile they are quietly drilling it into our children’s heads, and shooting out never-ending headlines of lies that never get retracted. Sick, sick stuff. And very frustrating.

It’s more about vanity than selling magazines. That and an amazing degree of insularity. There really is an illuminati vs. the great unwashed masses aspect to this business that is quite important is keeping the AGW train rolling down the tracks.

So you use a record that smooths and suppresses all short-term variation, and then announce, “Looky! the short-term variation (upward) is unprecedented in our record!” Uh, yeah.
