FLASHBACK: Twenty years ago today, the infamous "hockey stick" was published in Nature

Twenty years ago today: The infamous “hockey stick” graph that crystalized global warming and ignited the climate wars was published, and became known as MBH98. The science in it was so bad, it is credited with spawning the modern climate skeptic movement.

Michael E. Mann writes in the formerly Scientific American:

Two decades ago this week a pair of colleagues and I published the original “hockey stick” graph in Nature, which happened to coincide with the Earth Day 1998 observances. The graph showed Earth’s temperature, relatively stable for 500 years, had spiked upward during the 20th century. A year later we would extend the graph back in time to A.D. 1000, demonstrating this rise was unprecedented over at least the past millennium—as far back as we could go with the data we had.

Although I didn’t realize it at the time, publishing the hockey stick would change my life in a fundamental way. I was thrust suddenly into the spotlight. Nearly every major newspaper and television news networkcovered our study. The widespread attention was exhilarating, if not intimidating for a science nerd with little or no experience—or frankly, inclination at the time—in communicating with the public.

Nothing in my training as a scientist could have prepared me for the very public battles I would soon face. The hockey stick told a simple story: There is something unprecedented about the warming we are experiencing today and, by implication, it has something to do with us and our profligate burning of fossil fuels. The story was a threat to companies that profited from fossil fuels, and government officials doing their bidding, all of whom opposed efforts to reduce greenhouse gas emissions. As the vulnerable junior first author of the article (I was a postdoctoral researcher), I found myself in the crosshairs of industry-funded attack dogs looking to discredit the iconic symbol of the human impact on our climate…by discrediting me personally.

In my 2013 book, The Hockey Stick and the Climate Wars: Dispatches from the Front Lines, I gave a name to this modus operandi of science critics: the Serengeti strategy. The term describes how industry special interests and their facilitators single out individual researchers to attack, in much the same way lions of the Serengeti single out an individual zebra from the herd. In numbers there is strength; individuals are far more vulnerable.

The purpose of this strategy, still in force today, is twofold: to undermine the credibility of the science community, thus impairing scientists as messengers and communicators; and to discourage other researchers from raising their heads above the parapet and engaging in public discourse over policy-relevant science. If the aggressors are successful, as I have argued before, we all lose out—in the form of policies that favor special interests over our interests.

In the meantime, Climategate happened in November 2009, along with “Mike’s Nature Trick

by Jean S on November 20th, 2009

So far one of the most circulated e-mails from the CRU hack is the following from Phil Jones to the original hockey stick authors – Michael MannRaymond Bradley, and Malcolm Hughes.

From: Phil Jones

To: ray bradley ,mann@xxxxx.xxx, mhughes@xxxx.xxx

Subject: Diagram for WMO Statement

Date: Tue, 16 Nov 1999 13:31:15 +0000

Cc: k.briffa@xxx.xx.xx,t.osborn@xxxx.xxx

Dear Ray, Mike and Malcolm,

Once Tim’s got a diagram here we’ll send that either later today or

first thing tomorrow.

I’ve just completed Mike’s Nature trick of adding in the real temps

to each series for the last 20 years (ie from 1981 onwards) amd from

1961 for Keith’s to hide the decline. Mike’s series got the annual

land and marine values while the other two got April-Sept for NH land

N of 20N. The latter two are real for 1999, while the estimate for 1999

for NH combined is +0.44C wrt 61-90. The Global estimate for 1999 with

data through Oct is +0.35C cf. 0.57 for 1998.

Thanks for the comments, Ray.

Cheers

The e-mail is about WMO statement on the status of the global climate in 1999 -report, or more specifically, about its cover image.

Back in December 2004 John Finn asked about “the divergence” in Myth vs. Fact Regarding the “Hockey Stick” -thread of RealClimate.org.

Whatever the reason for the divergence, it would seem to suggest that the practice of grafting the thermometer record onto a proxy temperature record – as I believe was done in the case of the ‘hockey stick’ – is dubious to say the least.

Mike’s response speaks for itself.

No researchers in this field have ever, to our knowledge, “grafted the thermometer record onto” any reconstrution. It is somewhat disappointing to find this specious claim (which we usually find originating from industry-funded climate disinformation websites) appearing in this forum.

But there is an interesting twist here: grafting the thermometer onto a reconstruction is not actually the original “Mike’s Nature trick”! Mann did not fully graft the thermometer on a reconstruction, but he stopped the smoothed series in their end years. The trick is more sophisticated, and was uncovered by UC over here.

When smoothing these time series, the Team had a problem: actual reconstructions “diverge” from the instrumental series in the last part of 20th century. For instance, in the original hockey stick (ending 1980) the last 30-40 years of data points slightly downwards. In order to smooth those time series one needs to “pad” the series beyond the end time, and no matter what method one uses, this leads to a smoothed graph pointing downwards in the end whereas the smoothed instrumental series is pointing upwards — a divergence. So Mann’s solution was to use the instrumental record for padding, which changes the smoothed series to point upwards as clearly seen in UC’s figure (violet original, green without “Mike’s Nature trick”).

TGIF-magazine has already asked Jones about the e-mail, and he denied misleading anyone but did remember grafting.

“No, that’s completely wrong. In the sense that they’re talking about two different things here. They’re talking about the instrumental data which is unaltered – but they’re talking about proxy data going further back in time, a thousand years, and it’s just about how you add on the last few years, because when you get proxy data you sample things like tree rings and ice cores, and they don’t always have the last few years. So one way is to add on the instrumental data for the last few years.”

Jones told TGIF he had no idea what me meant by using the words “hide the decline”.

“That was an email from ten years ago. Can you remember the exact context of what you wrote ten years ago?”

Maybe it helps Dr. Jones’s recollection of the exact context, if he inspects UC’s figure carefully. We here at CA are more than pleased to be able to help such nice persons in these matters.

Two decades ago this week a pair of colleagues and I published the original “hockey stick” graph in Nature, which happened to coincide with the Earth Day 1998 observances.

Lucky coincidence that.

Sunsettommy

Coincidence or not, his statement here is B.S. as it contradicted DECADES of research showing that the MWP and LIA is real and significant.
“The graph showed Earth’s temperature, relatively stable for 500 years, had spiked upward during the 20th century. A year later we would extend the graph back in time to A.D. 1000, demonstrating this rise was unprecedented over at least the past millennium—as far back as we could go with the data we had.”

Greg

Shame this WUWT retrospective did not correctly summarise this frawwdulent science.
Mann did not graft, he cropped off the inconvenient end of the Briffa data and hid the cut-off behind another line, so it appeared that all lines were showing the same rise.
Jones DID graft , he went beyond what Mann had done because he cropped and then used the same coloured line to represent two different datasets and display it as a continuous line. That was what the WMO 2000 report used on its cover and was pushed all around the world. It is Jones’ version which is the iconic ‘hockey stick’ which the public knows, not Mann’s original MBH1998 graph.

Greg

comment image
Note the green line , Briffa’s data according to the legend. Except that Briffa’s data was cropped at 1960 and the temp record was GRAFTED on using the same line colour. This is what Jones refers to as “Mike’s Nature Trick” except that it goes way beyond crop and hide and into blatant scientific FRAWWD.

Greg wrote, “Except that Briffa’s data was cropped at 1960 and the temp record was GRAFTED on using the same line colour.”
Not only that, he rounded the splice points to hide the grafts.
 
Greg continued, “This is what Jones refers to as “Mike’s Nature Trick” except that it goes way beyond…”
I would not say that Jones was more dishonest than Mann. After all, Mann was complicit in Jones’ fraud, too. It is true that Jones did the dirty deed for the version on the WMO Report cover, but his email about it was addressed to Bradley, Mann & Hughes, and cc’d to Briffa and Osborn (who replaced Jones as CRU Director in 2016). Jones didn’t go rogue, the other five were obviously in on the scheme, as well.

“Earth Day 1998 observances?” Surely one only “observes” religious holidays.

N. Ominous

Earth Day isn’t a religious holiday?

Greg

Exactly what jumped out at me. The use of the term “Earth Day 1998 observances” even 20y ago, shows their attitude that it was like a religious duty. Part of their crusade for THE CAUSE.

Paul Courtney

My fellow Courtney: Top comment, and a zinger. My compliments.

R Hall

The Mann fraud gift that keeps on giving. Like VD.

Chimp

Lenin’s birthday.

HotScot

Am I correct in believing that Mann’s proxy data was extracted from a single tree?
Or has that become a bit of a sceptical urbane myth?

pameladragon

Pretty sure it was that single, unfortunate, Bristlecone Pine that he based the entire fiction on, but I could be wrong.

M Courtney

Nope.
It was Briffa who found a hockeystick by corrupting his entire dataset with one tree in, the Yamal peninsula.
See this for some of the worst science since Piltdown.
But we mustn’t be too hard on Briffa. If he wasn’t on “sick leave” from the CRU after this scandal came out we may never have had the crime of Climategate.
By which I mean that all the data that was gathered together into a HarryReadMe file would never have been found if he was there to protect it. Obviously he wouldn’t leak it himself so as the CRU had to circle the wagons and not throw him to the wolves.
That would be ludicrous. Although it would explain why the information was gathered in one place.

ralfellis

It was YAD061, the most influential and costly tree in the history of man (or Mann). It was the only tree in that group that showed a warming trend, so the study was heavily biased towards that tree. (How can a scientific study introduce a bias towards a particular component in a study….?).
That tree has cost the world about 4.8 trillion dollars, and counting. You could have encased it in gold and adorned it with diamonds, for much less.
R

MarkW

If they hadn’t found that tree, they would have kept searching till they found another proxy that suited their purposes.

Crispin in Waterloo but really in Potchefstroom

There was a data set weighting used, so that those trees with a ‘temperature’ profile that matched the desired shape more closely were given added ‘weight’. One of the trees was given a weight of more than 400 compared with trees that did not have the ‘right profile’.

JP

True. I remember, Steve McIntyre devoting quite a bit of time on the Yamal series

Gerald Machnee

It was not one tree, but the way his program worked, it was the dominant one. Read the left side of Climateaudit.org.

Dr Deanster

Yep …. Mann had his tree, and Briffa had a different tree. Both used Mann’s PC analysis or some such that weighted the data to the one tree. (Kudos to Steve McIntyre for successfully reverse engineering the beast and figuring out what was going on …. cause Mann and Jones weren’t about to give up the methods and codes). This whole debacle is what got me really interested in this whole Global Warming crap. I had just graduated grad school in environmental risk assessment, and to say the least …. I only thought the professors at my institution were corrupt … these guys took the cake …. and ate it too!

Chimp

They’d have to be scientists to give up methods and code.
But neither they nor consensus “climate science” in general practice the scientific method, in which results must be repeatable by others.

Bruce Cobb

Mickey employs the Big Fat Liars’ Strategy of; lie big, because a big lie is more believable, and when called on your lie, double down and pretend you are the “victim”, and a martyr for “the greater good”. It’s the passive-aggressive way. Because that’s how he rolls.

pameladragon

Mikey never met a split infinitive he didn’t love….

Bruce Cobb

I in all my days as a climate skeptic have never liked him.
But I do like an occasional split infinitive!

Gunga Din

Mann: I found myself in the crosshairs of industry-funded attack dogs looking to discredit the iconic symbol of the human impact on our climate…by discrediting me personally.

No, you discredited yourself. And continue to do so.
Who still promotes your “iconic symbol”?
How many filed an amicus brief in your support?
Why are you hiding your UVa emails?
Why do you file lawsuits instead of engaging in open debate if you are really a scientist?
Who pays your legal fees for you?
You are the attack dog.
Who’s holding your leash?

MarkW

The first lie is the claim that those who disagreed with him were industry funded.
The second lie is the belief that being industry funded proves that they are being dishonest.
The third lie is the belief that there is something nefarious in trying to shoot holes in other people’s work.

Gunga Din

Recycle time!
Stopping by Yamal One Snowy Evening
What tree this is, I think I know.
It grew in Yamal some time ago.
Yamal 06 I’m placing here
In hopes a hockey stick will grow.
But McIntyre did think it queer
No tree, the stick did disappear!
Desparate measures I did take
To make that stick reappear.
There were some corings from a lake.
And other data I could bake.
I’ll tweek my model more until
Another hockey stick I’ll make!
I changed a line into a hill!
I can’t say how I was thrilled!
Then Climategate. I’m feeling ill.
Then Climategate. I’m feeling ill.

Another Scott

The left always accuses the other side of doing the very thing they are guilty of.

Simon

And the right does the same thing.

Chimp

Simon,
Example, please.
Thanks!

HotScot

Simon
Agreed.
A bit like the UK Conservative party (Right) accusing the Labour party (left, and the opposition) of anti Semitism, only to find it to be true. The UK Labour party has admitted it’s anti Semitic.
But wait……..No such accusations against the Conservative party.
How strange.

MarkW

And along comes Simple Simon to demonstrate for us the art of projection.

Bruce Rouleau

And the world has been suffering the cost for that ever since.

Chris Norman

I always thought the context of Jones remarks were of little consequence. Someone who uses tricks to hide as a scientific method is obviously not to be taken seriously.

M Courtney

The argument is that “trick” meant ‘clever thing’ not a sleight of hand.
Of course that misses the point. There may be no intent to deceive others. But only because they have already deceived themselves and are now looking for self-assurance.

jon

“M Courtney April 23, 2018 at 1:36 pm

Yet “hide the decline” surely shows intent? “Hide” assumes an active process, not passive or incidental. Even without the “trick” it shows intent to install a false understanding in others.
This gives “trick” the aura of deception and sleight of hand.
What do you think?

Chris Norman,
“I always thought the context of Jones remarks were of little consequence.”
Judging by the willingness of so many to believe the superficial, erroneous interpretations of the emails, this seems to be a common idea among skeptics. It is an indication of how far some will go to find the truth – not very far. It’s more comfortable to make assumptions and listen to those who support one’s beliefs, allowing no other explanation.

Reg Nelson

They conspired to dodge FOIA requests, delete emails and data, black ball scientists who disagreed with them, and corrupt the peer review process.
It’s all there, in their own words. To paraphrase you: “Have you read the Climategate emails, Kristi?” LOL!

They were doing a LOT of bad things in those e-mails.

I suspect that most of us agree with what you call the “superficial, erroneous” interpretations of the emails because we have read them in context, and we have seen for ourselves that context makes no difference.
Many warmists have claimed that the emails have been taken out of context, but none, as far as I know, has been able to produce an example of a Climategate email whose context provides mitigation.

Kristi, you truly seem to have no clue here. Rather than mention a single instance that might support your laughable claims, you are simply throwing mud at the wall and hoping something sticks.
I submitted the first FOIA request to CRU, the one that set the whole madness in motion, and I’m one of the people mentioned by name in the Climategate emails. As such, I am much more aware than you and most folks here of the context because I LIVED IT.
If you’d like some context, you should read my post about what went on. It’s here.
My advice? Stop beclowning yourself regarding subjects about which you know virtually nothing. It just makes people point and laugh, and I assure you, they are not laughing with you …

Would you care to put forth an alternative, and in your mind, more proper interpretation of those remarks?
Or are you going to pull your standard stunt and just whine that other people aren’t being nice to you and demand that they stop it?

Joel Snider

‘It is an indication of how far some will go to find the truth – not very far.’
Just checking – this was the troll-flake who criticized posters for ‘not knowing what they’re talking about’.
This is also the same troll-flake who had the sheer, unadulterated gall to come to Watts Up With That, for God’s sake, and explain to all of us – complete with links to professional smears – where our movement came from – and why – and of course, who financed it all.
I mean, my God, this is arrogance to the point of farce – it’s a Far Side cartoon – ‘you may be a kangaroo, but I know a little about marsupials myself.’
All apparently under the impression she’s not being insulting.
But it does illustrate how far some will go to rationalize away the truth – pretty far.

Sporran

Many thanks to Willis.
I have just spent hours reading your excellent 2009 post and responses just agog with horror.
Trying to look up what happened afterwards to the CRU yields words like “exonerated”.
What happened please?

Kristi Silber

If you all would simply take my post literally, you would see that I’m commenting on a particular idea: thinking one knows enough from cherry-picked excerpts without looking at the context. I think this is wrong. I think it leads to misconceptions. The exact same thing applies to CAGW supporters.
I’m not defending Mann, Jones, or anyone. I’m urging reason. I’m battling bias, prop’ganda, hate and anger. I am trying in my teeny tiny, probably ill-conceived and certainly inept way to heal the deep divide in America today. I’m doing it all wrong, though. I thought maybe awareness of the way bias is spread (on both side) could slowly in some minds make a difference, but it’s the wrong tack.
I have genuine respect and admiration for the abilities of many people here. Their knowledge and experience goes far beyond mine. But we all have different knowledge and must make decisions for ourselves. I decide to limit my judgement of Mann and cohort not because I support them, but because I don’t know the whole story.
Limited judgement isn’t blindness, though. It seems pretty clear that they did not handle their data or data requests well and didn’t behave very professionally. The code issue is a little different, especially 20 years ago. It sounds like the FOIA wasn’t too clear when it came to computer code and intellectual property rights. (Imagine finally publishing research it took years to finish, and the next week having a dozen people asking for all data used, a list you don’t have, and the code for a computer program you spent weeks on – and knowing they want it so they can try to discredit your research, even if it means misrepresenting it.)
As for the rest, I don’t know. Jones seems more at fault to me than Mann. It comes down to whom one chooses to believe: the official committees that investigated, or the investigation by the contrarians (including the investigation of 4 of the investigations). My money is on the officials, partly because none of them knew how many more investigations there would be, and what subsequent groups might find. They wouldn’t stick their necks out to save these guys, especially if the emails were as clearly damning as the cherry-picking makes them out to be. Besides, I still have some faith in humanity and the integrity of scientific oversight. I believe people realize scientific misconduct cannot be tolerated in the profession, especially in such a controversial field.
None of us here has read them AND talked to the scientists involved and other scientists in the field about this. How many here know the story behind the peer review concerns, the apparent stifling of alternate views? What do you think it was about?
……………………………………………..
People here insult me. They may laugh at me. I’m sure plenty dislike and despise me, and they sure hate what they think I represent. It’s not easy. I didn’t come to make enemies, but neither did I come to make friends or have my ideas confirmed. I’m here because I love the beauty and wonder of life on our planet. I care about the potential effects of rapid climate change on humanity. And I’m here because I care about America and Americans.

Thanks, Sporran. The best source about anything Climategate related is Steve McIntyre’s blog. There is a “Categories” dropdown on the left, and it has a link to the “investigations“, better called “whitewashes”. In most cases they never asked the right questions, they were done by friends of the miscreants, and they often didn’t even talk to the principals.

Kristi, I took your post quite literally. I pointed out that I am not working from “cherry-picked” excerpts. I am not only looking at the context, inter alia I am part of the context. And I pointed you to my clear explanation of what went down, with all the context you could want.
In response, you come back, ignore my explanation, don’t say a word about everything I had in my post regarding what went on, you make the same accusations, and say that:

None of us here has read them AND talked to the scientists involved and other scientists in the field about this. How many here know the story behind the peer review concerns, the apparent stifling of alternate views? What do you think it was about?

I know the story about it, and you are doing your very best to ignore that fact. I wrote the first FOIA to UEA CRU, I’m the one that Phil Jones lied to, I’m the one whose FOIA they were making up stories to avoid, I’m the one that their emailed excuses were sent to, I’m one of the few mentioned in the emails, so your claim is total crap. No other word for it. Absolutely bogus.

People here insult me. They may laugh at me. I’m sure plenty dislike and despise me, and they sure hate what they think I represent.

Oh, please, you give yourself far too much credit. I just think that you are incredibly biased and dense and unwilling to admit when you are wrong, but I don’t “hate what you represent”. Nor would I waste one second disliking or despising you. You’re not worth it. I save those for people that actually make a difference. Seriously, it’s time for you to follow the FIrst Rule of Holes, which says:

When you find yourself in a hole … stop digging.

PS—As I mentioned below, there is an explanation of what you laughably call the “investigations” here. Note also that a UK Parliamentary Committee said that criminal charges would have been brought for their attempts to avoid my FOIA, but the Statute of Limitations had run out by the time they got around to it …

MarkW

Kristi, since you’ve never read any of the CliimateGate emails, you have knowledge regarding how much context is necessary to understand.
As a result your whining is merely more evidence that you will say anything in order to distract from the problems that others have been poking in your favorite gravy train.

The full set of Climategate emails are here:

Willis,
“In response, you come back, ignore my explanation, don’t say a word about everything I had in my post regarding what went on, you make the same accusations, and say that:”
I’m very sorry Willis, I wasn’t replying to you there; for some reason I don’t think I’d even read your post, I was actually thinking of Tim Ball’s article moved from another site, not yours. It was short excerpts with interpretations and no context. Tracking down the full context could be impossible without the conversations behind them. I know how condemning they look.
How do you know you were first, Willis? You sure weren’t the only one.. Was it a coordinated effort at CA? Why would multiple people there want the info? Sounds like McIntyre was even more persistent than you. There may have been others, too, doing the same thing.
Was CA the other to get the emails from the hacker?
I read your exchange at the link you sent. I have a different perspective on it, too long to go into here.
“”Oh, please, you give yourself far too much credit. I just think that you are incredibly biased and dense and unwilling to admit when you are wrong, but I don’t “hate what you represent”.”
I give myself credit for some things, but not much, I can admit when I’m wrong. For instance, I’ve lately come to think that because of my image of the Earth as zillions of interactions, each potentially affected by climate change, I may be overestimating the ecological problems. But who knows? I don’t.
We are all biased.
I am not dense.

That’s why I’m here. Thanks Mike.

Pretty much the same for me, not so much because it was crap work, but because of the large number of people that were defending such blatant statistical silliness. That made me realize how political this was and un-scientific. Had the scientific community correctly pooh-poohed the work things could be quite different now for many of us.

I was trained to be skeptical and when the CO2 CAGW issue was articulated in the late 1970’s I paid attention and came to the conclusion that the analysis of the data was flawed. CO2 Lagging Temperature change, the absorption spectrum inverse log relationship to doubling of concentration and finally the assumptions in the models appeared biased against any other warming mechanism. Including insolation Milankovitch cycles and solar flux. As Darwin said your peers will regal them selves showing you where you have misinterpreted the data. Well the facts surprisingly fell on deaf ears and this was against everything I was taught. Even Kunn would shake his head, Popper would simply dismiss it as “not science any longer”. . With the publishing of the Michael Mann “Hockey Stick” and Steve McIntire’s rebuttal it became clear that there was another horrible beast at work and it was all about poitics and water melons not about science. That was the end of it for me.

OweninGA

That’s what tipped me off that the whole thing was off the rails. It conflicted with too much known history around the world. What’s more it made these extraordinary claims that all that history was wrong, but offered no explanation for what mechanism caused all these historical records to be so far removed from truth. It couldn’t explain the Greenland colony. It couldn’t explain the Roman mines covered by several thousand feet of ice. It was just wrong on all counts.

John Endicott

Indeed, the believe in the CAGW narrative requires one to be ignorant of historical knowledge about the climate.

MarkW

Having just spent a decade fighting the great ozone hole sc@m, I was already a skeptic.
When I heard that the hockey stick had eliminated both the MWP and LIA I was pretty sure that the same people were launching the next sc@m, and I was right.

Matt G

I was skeptical before then (1998) because I believed global warming was caused by ocean cycles hiding solar influence after a few years originally believing in it. I had been researching ocean anomalies since about 1995. That’s when I first claimed global temperature records will only occur from the strongest El Nino’s and the one in 1997/98 only strengthened my ideas. The Mann always trying to change history brought alarm bells ringing with this first infamous hockey stick.
Alarming, just some examples:-
1) Instrumental data added to proxy data.
2) Removing well known periods in history verified before using proxy data.
3) It become clear that data used was cut short after to hide the decline in them.
4) One now well known Biffa proxy showed significant warming where generally none of the others did.
https://climateaudit.org/2009/09/26/briffas-yamal-crack-cocaine-for-paleoclimatologists/
5) Random numbers always returned a hockey stick
6) The graph couldn’t be recreated, just like Mann’s GISS.

Kristi Silber

Dave Burton,
Been reading your links. First one:
“Yes, we’ve learned out lesson about FTP. We’re going to be very careful in the future what gets put there. Scott really screwed up big time when he established that directory so that Tim could access the data. Yeah, there is a freedom of information act in the U.S., and the contrarians are going to try to use it for all its worth. But there are also intellectual property rights issues, so it isn’t clear how these sorts of things will play out ultimately in the U.S.” (Mike)
“Just sent loads of station data to Scott. Make sure he documents everything better this time ! And don’t leave stuff lying around on ftp sites – you never know who is trawling them. The two MMs have been after the CRU station data for years. If they ever hear there is a Freedom of Information Act now in the UK, I think I’ll delete the file rather than send to anyone.” (Phil)
First, this is an unnamed file or files they are talking about. We don’t know what it is, and they don’t know the kind of things they will have to hand over. They certainly aren’t going to delete the whole ground station data set just because of an FOIA request. It might be some work they’ve done that they don’t want to get into the hands of the enemy just because they don’t want to make it easier for them – and there is no scientific standard saying they should. Replication, the excuse for wanting the data, should be from the ground up to avoid repeating the mistakes of the first study. The skeptics wanted CRU’s work to try to find apparent weaknesses and trumpet them. The skeptic scientists ARE enemies of the mainstream – they have made themselves enemies through unprofessional practices, like publishing research on blogs and saying publicly that science as a profession is not trustworthy, or scientists are corrupt/biased.
Then there is an intellectual property rights consideration. The FOIA had just begun in the UK, and the scientists weren’t sure what was covered. It wasn’t the norm in climate science to share computer code or analyses (according to the House of Commons Science and Technology Committee – Eighth Report
The Disclosure of Climate Data From the Climatic Research Unit at the University of East Anglia). This report found the UEA more at fault that CRU because it didn’t provide better support handling the many and sundry requests.
That’s just my argument concerning the first link. I have arguments about the other links I read, too, but I am not going to take the time. The main point is that there is stuff we don’t know, and messages can have very different meanings than they first appear. There are people behind the emails who know each other, may know if someone is kidding without an emoticon, and they are human. They say dumb things, say they will do things that they don’t do. You can’t convict someone on the basis of something he says he will do.
The case of Phil deleting files may have occurred after the FOIA request. Scenario: He gets the request, hands over what he has to, then spends a day deleting all emails with names of skeptics to avoid it happening again. There is nothing illegal about that.
I’m not trying to defend these guys. I’m saying that often there are alternative ways of looking at things. We don’t KNOW what they meant all the time.

That Graph is 100% completely irreproducible independently. Nature Tricks to Hide the Decline are unique to the person making up the dataset. You also have to ignore instrumental data until 1902. What a complete joke.

rgirouard@sbcglobal.net

Your very accurate comment that the Mannian Graph™ is completely irreproducible leads me to think that Mann et al should have published their results here:
http://www.jir.com/ which is the beb site for the Journal of Irreproducible Results.

rgirouard@sbcglobal.net,
One of my all-time favorites. Used to read in college a few decades ago, but have not kept up with for a while. My dad was an engineer, and one Christmas, when I didn’t have a lot of money, I found a JIR book in a book store and bought it for him. My favorite article from way back when was on quantum baseball. If you haven’t seen it, think of the uncertainty of whether a base runner is on base or not.

jir looks like its been well dead for 10 years.

The Deplorable Vlad the Impaler

Two of the best articles I ever saw in JIR were: “Nutrition of Pet Rocks” and the ever-famous Dietz and Holden’s “Fake Tectonics and Continental Drip”. JIR was a gem; it allowed otherwise serious scientists to poke fun at themselves and show that they actually had a sense of humor (h/t, Bill Murray, “Ghostbusters”).

So long as the Primary Media Outlets control 90% of the message board the Propaganda Ministry controls tone, tenor, volume and frequency of information. With that much power they can run cover for the alarmists and bury the truth while promoting the make believe. 80% of the population are too busy devoting the majority of their bandwidth to living their lives not knowing that Government Funded Science is playing a long game to control those lives. The Government is winning.

Current events and popular opinion suggest otherwise.

Alan Tomalty

Nothing in my training as a scientist could have prepared me

Because being trained as a scientist does not prepare you to defend pseudoscience.

I found myself in the crosshairs of industry-funded attack dogs looking to discredit the iconic symbol…The story was a threat

I agree that the hockey stick graph is nothing but a symbol (a cult symbol) and the paper it originated in merely a fictional story. But it’s a complete lie that any industry first “attacked” the Grimace impersonator; it was first independent statisticians and hundreds of researchers that had studied the LIA and MWP that immediately discredited the fictional story you put together using pseudo proxy data.

I gave a name to this modus operandi of science critics: the Serengeti strategy.

Again, we see the words of an egotistical out of touch mook. First of all, all criticisms of the pseudo science was correct rebuttals based on scientific grounds. Secondly, there is already a name for the purported attacks you describe but it is your MO to completely ignore scientists that have come before you.
But please, keep on with your charlatan ways. You will soon be the face of scientific disgrace and your work used as the example of pseudo-science posing as science for future generations to learn from.

Apparently that training didn’t stick…, or maybe Mikey’s just untrainable.

John Endicott

I think he was out playing hokey when those lessons were being taught. 😉

ralfellis

I still dont buy the tree ring thermometer theory. Tree growth is effected by so many things, like moisture, competition, predation, that it is a leap of faith to say that tree rings are primarily governed by temperature. For instance, a really hot UK summer will produce thin tree rings, because there is often not enough moisture during a hot summer.
Plus I was looking at rings recently in cut pines, and the trunks had wildly different ring thicknesses in different quadrants within the same trunk. One quadrant may have a sudden burst of thick rings, that was not represented elsewhere on the same trunk. So if you took cores from these trees, you would get a different temperature profile for every trunk quadrant that was drilled…! From a dozen trees, you could achieve an infinite variety of temperature profiles.
Ralph

April 23, 2018 at 1:46 pm
Yes, I quite agree. Perhaps by sampling multiple trees you could eliminate quadrant variation and competition issues…but then how do you reliably sort out temperature from moisture changes/availability?
However, I’m not a botanist. I would think they would/should know.

There is no such thing as an undisturbed tree.
https://youtu.be/AihvuZiDhsg

ralfellis

This sort of thing. On this larch trunk there is strong growth in the 7 oclock position at about 22 years, suggesting a warm climate. But if you took the core in the 3 oclock position, the warm years disappear. And I saw some pine trunks with greater discrpancies than this.comment image

Ralfellis, you just don’t understand how to read the treemometer … here’s my diagram explaining the inner secrets.comment image

The same goes for the oak trees I cut for firewood.
There is a rough seven year drought cycle that is often visible.

Urederra

The “funny” part of Mann´s hockey stick is that it is not a temperature vs. time graph but actually a tree ring thickness vs. time. Where thicker rings mean higher temperatures, because trees grow faster at higher temperatures.
I would be worried if the blade of the stick had gone down, but the blade goes up, meaning that the trees grow faster, and that is a good thing.
Mann´s real “genius” is making us believe that trees growing faster is a bad thing.
(Yes, I know Mann´s hockey stick statistical issues)

Sandyb

I so agree with you. I would love to see some articles debunking tree ring data. Ice cores also are just as innaccurate and useless. A list of all factors affecting both would be quite lengthy indeed.

OweninGA

Ice cores aren’t useless, but the temporal and concentration error bars are much larger than usually given if you are trying to represent the “ambient atmosphere” at the time of firn formation. If you are just reporting the concentrations in the bubbles then the error bars are fine, but they are probably off by quite a bit for the atmosphere.
What I am saying is, they, like most proxy data, can give a general impression, but should in no way be considered precise. They are what they are and nothing more. Too many climate press people tend to make outlandish extrapolations about the implications of a paper. Many times the paper does not explicitly (or implicitly) support CAGW, but does throw a sop to it in the conclusion to get the paper past the gate-keepers. Reading the results sections is sometimes an enlightening experience.

Matt G

Ice cores are now where near as bad as tree rings because the latter can’t be distinguished between two main conditions, precipitation and temperature. Tree rings are determined by sunshine levels, CO2 levels, water content, minerals in ground and temperature. Ice cores are only dependent on snowfall pressed down to ice, trapping the atmosphere at the time.
http://www.antarcticglaciers.org/glaciers-and-climate/ice-cores/ice-core-basics/

MarkW

Another point is that trees have a temperature at which they grow best. Going above or below that temperature means less growth. So even if everything else was being held equal (an utter impossibility), you would still need to know whether the temperature was above or below the optimum temperature before you could know if increasing tree ring widths meant the temperature was increasing or decreasing.

M Courtney

That’s a very good point.
It’s less complete than including nitrates and sunshine and moisture but far more pertinent. Even if all else were equal (like a school quiz) it still couldn’t give you the answer.
Let’s just stick to counting the rings and knowing the age.

OweninGA

Yes, but the argument is that the tree has a longer growing season inside the perfect bubble it will have a wider ring. (Do I believe this – not really though there is some truth). If the tree leafs out in April instead of May and doesn’t drop foliage until October instead of September, then theoretically, it would have a wider ring (all other factors being impossibly equal). Of course if it got too hot for a couple of months or there was no rainfall for a couple of months, etc, all things would not be equal.

ralfellis

And if tree rings are not primarily controlled by climate, then how can dendrochronology ever work? How can you compare your wood sample, grown in a micro-climate in East Anglia, to a reference sample grown in a different micro-climate in Ireland ??
The whole thing soulds like voodo-science to me.

It should be referred to “Lenin’s Birthday” which is the true insider Earth Day spirit of the event. Far more to the point.

Andy Pattullo

I believe the Serengeti lions choose their victIm based on several key traits: weak, lame, unfit, inept, incautious, cognitively impaired, diseased and just generally incompetent when it comes to defending their position.

Paul Courtney

Andy: Well, the lions also choose the “victims” chosen by big oil. According to Dr. Mann’s version. And he knows how to pick ’em.

Michael Mann is a lying liar who spends his spare time lying. Among the biggest is a lie of omission. He was found to have committed a grievous mathematical error in the original Hockeystick calculations (failure to center the data before the principle components analysis).
He also neglects to mention that he used post hoc proxy selection. And he doesn’t think it’s worth noting that his method will “mine” hockeysticks out of red-noise data.
He is as far from a scientist as a man could possibly be—opaque, dishonest, and completely without principles … in fact, I’d say he specializes in unprincipled component analysis.
For more of his slimy double-dealing, see here … and for the true story of the hockeystick, see ClimateAudit.
w.

M Courtney

I agree with all that. Which is rare when someone uses the word ‘liar’. In Mann’s case I agree with that.
Except…

he used post hoc proxy selection

That one statement is not proven.
It is not contradicted by the evidence. But it is not proven.

Surely, the post hoc proxy selection is proven. It’s the process he used to “mine” the hockey-stick shape. As w has reminded us, the method even creates a hockey-stick from red noise data. For anyone new to all this: climateaudit is a stunning read (w gave the link, above).
But there was more post hoc activity than that. He truncated the proxy data where the divergence started. Maybe not “post hoc proxy selection” in the usual sense, but nevertheless a form of post hoc proxy selection. A much more egregious one.

M Courtney

Mike Jonas, So he fooled himself and then didn’t discard results that fit his folly?
That’s a whoopsie.
That’s my theory. That’s what I see happened.
But it’s not “post hoc proxy selection” in the usual sense. In the malevolent sense.

It’s just possible that, at the start, he fooled himself. The process he used seemed reasonable: use the proxies that best fitted observations. But as any mathematician can tell you and as Steve McIntyre demonstrated, it’s heavily flawed. What happened next – Michael Mann doubling trebling and quadrupling down on the error in the face of sensible serious and substantiated criticism of his work – showed his ridiculous lack of any kind of scientific rigour, his absurd bias, and hence his absolute unworthiness. Perhaps the saddest part of all is that very few journalists have shown even the slightest understanding of how they have been played as fools for 20 years.

MarkW

Mike, they haven’t been “played”. They are willing, perhaps even eager, participants.

Edwin

Yes Willis but some university gave him a degree (s) in science so he believe he must be one. It does matter that he missed the point of Scientific Method altogether or maybe like some of the advance degree people I once managed he was never taught the subject to begin with.

Crispin in Waterloo but really in Potchefstroom

Willis
“(failure to center the data before the principle components analysis).”
Small correction, I recall. He centered the data, but he chose to center it on the 20th century portion, not the whole data set he was analysing for principal components. That was a major error. When the data is properly centered over the whole data set, the MWP re-appears.
Personally I believe that he made the error deliberately, the alternative being that he was too incompetent to perform the calculation correctly. He knew what he was doing so the misrepresentation of what the data said was deliberate.

Robert Austin

I still chuckle at the diagnosis of “Mannchausen Syndrome by Proxy”.
Definition from Wikipedia with select alterations to suit dear Mikie:
Mannchausen syndrome by proxy (MSbP), is a condition wherein a scientist fabricates, exaggerates, or fabricates climate health problems for those who pay their salary (taxpayers), with the primary motive of gaining attention, adulation and grants from said taxpayers.
In case there are those unfamiliar with the satirical reference, there is an actual psychological syndrome called Munchausen Syndrome by Proxy.

Mickey Reno

Mann, Jones and the other hockey team members have committed many egregious assaults on science. They conspired to eliminate the medieval warm period, to flatten out the little ice age, to ignore climate history of the Holocene, to pretend that major climate drivers unknown to them could not be possibly influencing modern temperatures, that science must pick one winner from among competing but uncertain probabilities, and that correlation can equal causation for adequately complex systems.
They began a corrupt regime of nearly instant citations of their own and their friend’s papers to give them i credibility in the IPCC assessment process. They accept and promote pal-reviews of alleged peer-reviewed science. They corruptly conspired to thwart papers and even whole journals they suspected would be critical of them or run counter to the hockey stick message. GCM climate modelers likewise somehow have installed a new corrupt and unscientific paradigm of exempting their own hypotheses (virtual climate models) from falsification testing. They’ve begun to finesse a post-normal message that these toys have become infallible, proven science, guiding data elimination in the ARGO float dispute.
The use of statistical tests not demonstrated (scientifically) as being fit for purpose abound in climate science. The need and desire to make hockey sticks drives tendentious proxy selections in both the Northern and Southern hemispheres (Mann, et al. Pages 2K, Gergis and Karoly, et. al.). And plain faulty analysis like that of Camille Parmisan and her butterfly studies, when married to aforementioned unscientific GCMs, mean that the biological impacts of CAGW are guaranteed to mirror the tendentious conclusions of the hockey team, and thus give false credibility due to cross-discipline matching results. And now social scientists and social and political activists have learned how to pile on and thus guarantee their own funding, needing only to find some temperature stresser to humans, communities, animals or biomes, and then marry a guaranteed upward projection of CO2 based climate models to multiply that stress, in a way that can draw nearly any desired bad conclusion, and thus forever ensconcing this alleged future “damage” into the scientific record.
These men and women have harmed science, and are still doubling down on their corrupt methods. It won’t stop until these methods stop, and people again start to ask honest questions of nature, rather than to presume they already know the answer and then set out to prove it. To get science’s mind right, this “proving” has to stop and the disproving needs to reassert itself. The publication of a paper has once again to be seen as the beginning of its replication and verification, not the conclusion of some objective truth.

Kristi Silber

Willis,
I have read your smooth operator story. First I want to commend you on your work. I wish I had the understanding of math and statistics that you do.
Then I want to comment on the fact that you didn’t get this published. I’m not criticizing you, I’m trying to pose a different way of seeing the experience.
You say, “After the usual long delays, they said I was being too hard on poor Michael Mann, so they wouldn’t even consider it ”
Now, is that really what they said? What was the real comment?
If you think it was rejected because you submitted it to Mann’s friends, that suggests you believe it was critical of Mann. The question is, why did you phrase it in a critical way rather than a purely constructive one? Why use his data rather than a neutral set? And why on Earth would you take out all references but those to Mann, and resubmit to the same journal? That just makes it more like a personal attack. You would have had to know that there was controversy over the “hockey stick” and that the whole community was sensitive about what might be construed as a biased attack from a skeptic layman. (Just trying to think in their shoes here.)
In the intro you say, “[3] He then goes on to say that the best choice among these methods is the one that minimizes the mean square error (MSE) between the smoothed data and the data itself:” As evidence, you follow it with a quote from Mann, “That constraint providing the minimum MSE is arguably the optimal constraint among the three tested.” However, the two statements are not the same, and it’s not a logical step to then go on to say, “[4] However, there is a better and more reliable way to choose among these three constraints.”
Do you see how “better and more reliable” is not appropriate here, when you’ve quoted and said nothing about the actual method they’ve used?
Even strangers to Mann might have rejected this, IMO. Your intro is half quote. You only have one citation. Your graphs are at different scales, making the curves look different. You only use Mann (and Jones, et al., which wasn’t in your references list); you should have used a different data set if you didn’t want to come off as picking on him. It’s odd addressing only Mann’s work and using Mann’s work through the whole thing without actually referring to it in the title. Your discussion section is weak: it’s nothing but a summary of your methods, and this is not professional.
None of this is a comment on your actual work or its value. You have to understand that there are professional standards of presentation, background, the use and criticism of others’ work. By your own admission, you had little experience with scientific publication at the time. And this is a prestigious journal.
I also don’t think it’s correct to assume that someone actually stole your idea. Considering the intervening time, it’s possible that someone vaguely remembered reviewing your piece, thought of the truncation, and brought it up to someone else. I don’t know. It’s also possible you’re right, but the thing is, you don’t KNOW that.
Willis, you give as evidence of Mann’s wrongdoing a bunch of stuff written by contrarians, on a skeptic blog. I have no more reason to believe them than I do Mann. In fact, I have less reason because I’ve seen the way they operate. I’ve seen the bias. I have no reason to trust anyone who ends a treatise trying to prove wrongdoing in someone’s work,
“I suspect that the whole episode has wider social significance as an indicator of a rather defective aspect of early 21st century scientific culture.”
THAT is propaganda. Besides, why is an economist critiquing the work of a climate scientist??? Doesn’t that say something? Aren’t there supposed to be plenty of skeptical climate scientists around?

Joel Snider

Gee, Kristi – Steven Mosher called Mann’s actions ‘pretty close’ to criminal.
And by the way – putting an algorithm in a model to automatically produce a graph is a common trick in industry – something economists are trained to spot, but a climate scientist like Mann thinks he’s real clever, pulling a fast one.
If you take the time to read Mann’s e-mails, you will find him to be a stuck-up, contentious, Progressively bigoted little twerp, who rankled the feathers of even his close associates.
And self-declared ‘climate scientists’ are not specialists – they depend upon a wide variety of disciplines, of which they are not experts in. And then they discredit the criticism of a specialist in the field, by saying ‘they’re not a climatologist.’
See, THAT is propaganda. As is the constant, vague references to ‘possible’ consequences, or exactly what the ‘97% consensus actually means’ – usually a statement most skeptics would agree with – something to the effect of ‘C02 is a greenhouse gas, and humans are contributing.’ or ‘Climate Change is real.’
AND the fact that there are so few academics who will come out as skeptics should tell you something about the culture, and how ‘contrarian’ views are chased off campus like witches.

Chris Wright

Absolutely. The very fact that it’s based on PCA is in a sense fraudulent. Everyone who has not studied the hockey stick will think it’s a graph that shows the average of the proxies, which thus gives an indication of the climate. But it’s actually PCA, which is not an average. If you want an average all you have to do is take the average. Trouble is, that didn’t give the result he wanted i.e. a hockey stick.
The proxies Mann used mostly showed a clear MWP and LIA signal. But Mann’s method efficientyly removed them. It literally got rid of the MWP.
That a scientific fraud still gets scientific awards shows how corrupt the climate establishment is.

Jacob Frank

I could really know nothing about science and just deduce from the way Mann talks and using common sense know everything he is talking about is pure horseshit. If proper science needs an open mind this dude has zero science credibility.

Steve McIntyre explained the Mann/Jones/Hughes/Bradley/Osborn hockey stick very well here:

If you watched that lecture then it will be obvious to you why Jones was so terrified of Steve McIntyre’s analytical powers that, in a 2/2/2005 email entitled “For your eyes only,” Jones told Mann that if Steve McIntyre and Ross Mckitrick file a FOIA request for the CRU station data, he (Jones) planned to delete the data rather than release it to them:
http://archive.is/f2hjr#selection-9.2013-9.2319
Richard Muller’s discussion of the hockey stick was also very good:

Coeur de Lion

The police never found out who did it. I don’t think they tried very hard. It was all too disgraceful. It was clearly an insider with knowledge of UEA servers

M Courtney

Or knowledge of the IT guy who had knowledge of UEA servers.
Anyone in authority – academic staff – are in that group.

Tom in Florida

I seem to recall reading one email, but perhaps incorrectly, that Briffa was upset about how his work was being used. Perhaps it was he, under the guise of being away on leave, that assembled and left open the HarryReadMe file.

Gunga Din

Huh?
I thought it was the Russians. /sarc

M Courtney

Perhaps…
But who asked for all the emails to be gathered together in one place as the HarryReadMe file anyway?
Forget the Russian hacking. The policy believe the Russians had a sleeper in the UEA CRU to arrange this. Which means they sleepers everywhere.
There may be less paranoid explanations.

Tom, you might be thinking of one of these:
Climategate I:
“bullshiting and politiking in various meetings… try to convince myself that this is of use to us as a dendrochronological community…” -Briffa 0846715553.txt
Climategate II:
“I find myself in the strange position of being very skeptical of the quality of all present reconstructions, yet sounding like a pro greenhouse zealot here!” -Briffa 2009.txt
Whoever the brave Climategate whistleblower is, (s)he deserves a knighthood or damehood,

Like Dec 7 1941, another day that will live in infamy.

The infamous “tree” was from research done by Dr. Ken Briffa wherein he used a fossilized tree ring that was an enormous outlier within a very small sample set form the Yamal Peninsula. No legitimate scientist would do such a thing. Steve McIntyre referred to it as the most influential tree in the world

Joel Snider

I’d like to see a compilation of apologist excuses for it.

michael hart

Nature’s famous “Mann Trick”. The Climate-gate emails revealed that the usual suspects used to joke about it with each other, such was their contempt for Science. Worse still, it encouraged a younger generation to think it was OK to do this sort of thing.

Herbert

Which reminds me. How is Dr. Mann’s litigation against Mark Steyn et al going in The Federal Court in Washington,D.C.?
I must re-read “ Steyn’s “ A Disgrace to the Profession”.
I wonder who will front for Mann to defend the legitimacy of the Hockey Stick in court?

Edwin

My guess is that Mann saw an opportunity to become famous, go down in history. It is one reason why some get into science. They dream of being an Einstein, Darwin, Galileo, etc. They are looking for a form of immortality. UN-IPCC reports were in the second edition but not selling too well if I remember correctly. A “pretty, simple picture” showing how dire AGW is what was needed in Mann’s mind. Something all the news media would run with and plaster all over. I doubt the media that ran it at the time ever even asked what an anomaly was or noticed that even if you believed Mann’s hockey stick that it was only talking about a little more than half a degree. They certainly didn’t ask how one determine temperature of the Earth from a tree ring.

pameladragon

IMO, you are correct. Mann is a small man with a poor grasp of how science works. He will get his fame, however, right up there with the Piltdown hoax, as a total disgrace to his chosen profession. It is ironic that he hails from Penn State….

Sandyb

Here is what is being taught to our kids. Arg!, https://www3.epa.gov/climatechange//kids/documents/tree-rings.pdf

Simon

Seems pretty reasonable.

M Courtney

Tree ring patterns provide information about precipitation and other conditions during the time the tree was alive.
Scientists can learn even more about precipitation and temperature patterns by studying certain chemicals in the wood.

The unreasonable part is disentangling the precipitation and the other conditions.

The hockey stick is the result of multiple mathematical errors that are not well recognized in the social sciences.
The most significant error is “tree ring calibration”. This is better known as “selecting on the dependent variable”.
The problem is that a statistics rely on a sample being random. But when you calibrate tree rings you no longer have a random sample.
As a result your statistical methods return bogus results. this amplified the instrument signal post 1850 and amplified the noise pre 1850, resulting in a hockey stick shape regardless of the proxy data.
It didn’t matter what data you used. Tree rings or any random garbage numbers. If you calibrate you end up with a hockey stick shape.

Mann had to make sure they didn’t ‘dilute the message’, ‘provide fodder for skeptics’, hand over data ‘so they could find something wrong with it’, and if they did it would result in ‘pure scientific fraud’.

Have you read it? Hard to argue with any of it I would have thought.

Earth has warmed twice as fast in the last 50 years as in the 50 years before that.

This is an error.
Have a look at what the real temperatures from the UK MET Office.
Although NASA are correct when tey say that the wotrld has warmed since teh end of the LIA adn thus t s warmer now than then.
But that is not what NASA says here:

Well, after observing and making lots of measurements, using lots of NASA satellites and special instruments, scientists see some alarming changes. These changes are happening fast—much faster than these kinds of changes have happened in Earth’s long past.

Hard to agree with any of that from a reality-based point of view.

EternalOptimist

If you had nothing else to go on, no other evidence, I can see why you might look at tree rings. But there is other evidence, so why oh why was Manns nonsense ever given the weight it was ? why was the more substantial evidence submerged ?

pameladragon

Easy, because he gave the IPCC what they needed to get the pols on board. There is ample evidence that the MWP and LIA happened and were not isolated instances. That was all I needed to spot a bogus graph. But it was reassuring that McIntyre and McKitrick
showed up the maths as being hinky.

Chimp

Because he gave “climate science” what its voodoo practitioners wanted, ie to “get rid of the Medieval Warm Period”, which, with the Roman, Minoan and Holocene Optimum WPs, were all hotter than the Modern WP, without benefit of current CO2 levels.

The NASA kids education page has always made me sick.

And they say science self-corrects.
Only a statistically illiterate reviewer would have ignored the sudden reduction of variability of this signal (sigma/mean) during the hockey stick. Now after spending trillions of dollars, this obvious massaged data will be put to fake cemetery. Yet the instigator, just like Harvey Weinstein, is roaming free, claiming innocence and laughing at our gullibility.
I would dearly love someone expose the names of these now infamous reviewers. May they rot in hell.

It is quite possible climate researchers like Jones were selected to do the review and were simply out of their depth to spot the problems in the math.
I have met many people over the years that cannot for the life of them follow why calibration is a problem mathematically.
Two years ago there was another temperature reconstruction that again used a form of calibration.
People have a very hard time grasping the problem. And even when they do they fail to recognizes that they have managed to create another variation of the problem in their own work.
it would not surprise me at all to find that the reviews were done in good faith. Incompetence is much more common than malice.

pameladragon

“it would not surprise me at all to find that the reviews were done in good faith. Incompetence is much more common than malice.”
Yes, I agree, but when the error is pointed out by so many and in such easily-understood language, the honest incompetent is likely to backpedal and admit his error. This is where the malice creeps in; Mann is totally convinced of his rightness and righteousness. He is unlikely ever to admit he made a boo-boo. When he is cornered he lashes out with a vigor usually reserved for cornered Wolverines or Badgers….

The problem with tree ring calibration is that the error is counter intuitive. It seems like a good idea to give some tree ring greater weighting than others. Based on how reliably they appear to follow temperature.
Similarly it seems like a good idea to give those patients that took the medicine greater weighting than those that didn’t.
The problem is the patients may not be responding to the medicine and the trees may not be responding to temperature.
By excluding the negative cases and only including the positive cases there is no way to know.
Some of the greatest blunders in science have resulted from this error, because it yields false positives/negatives to almost every hypothesis. yet it sees so logical.

Bill Taylor

random numbers fed into that program would yield a hockey stick every time…….

Kristi Silber

I don’t agree with some of the things Mann has said, and he tends to focus on his sob story too much. I don’t think he’s a good representative of scientists. I think if there were errors in the hockey stick graph he should have come out and admit them. He was just a postdoc at the time, so it’s not like his life would have been ruined, but on the other hand the graph was so widely publicized, it would be hard to admit. Errors are one thing, fraud is another. Since the graph has been reproduced with many data sets since, it’s not really a big deal if there were mistakes in the first. Then again, presumably the investigators went through that, too. I’m not fully convinced there errors, even though I’ve read McKitrick (2014). That paper ended,
“I suspect that the whole episode has wider social significance as an indicator of a rather defective aspect of early 21st century scientific culture.”
and to me this makes the whole assessment suspect. Anyone who makes a statement based on one incident is intentionally spreading an opinion that has no basis in fact, but at the end of a scientific paper it has the veneer of authority. This is an abuse of the authority of science no less that it would be for a Jones or a Mann or a Schmitt to say at the end of one of their research papers, “I think my analysis of the Soon research shows that contrarian scientists are all in the pocket of Big Oil.” It is not appropriate, nor is it right, and neither was McKitrick’s comment. It also talked about interviews and testimony, characterizing one excerpt thusly:
“Translation: … Yes. When we removed them the graph collapsed and the statistical scores went to zero.”
Yeah, sure. That’s what he said. This is a “translation” of a short excerpt from a long comment. In English.
……………………………………………
To me it seems as if the skeptic community is so bent on believing the mainstream scientific community is corrupt, they won’t believe the evidence otherwise. The fact that 8 investigations all cleared CRU of scientific misconduct means nothing. Too many believe someone’s interpretation of email excerpts rather than wonder what the full story is. They believe the superficial rather than the deep.
I don’t know the full story. I’m not enough of a statistician to assess that argument. I agree that there was poor handling of data and source code (although things were different then, and part of the problem was evidently about someone else’s intellectual property rights, and i can understand getting frustrated handling endless requests…the whole department wasn’t set up well to deal with requests), but the good thing is that it led to the wide, easy availability of other data.
This happened 20 years ago. One incident. There is no reason to believe it’s indicative of general corruption. Although there have plenty of accusations of fraud and corruption since, there is nothing to support them. They come from outside the mainstream climate science community and are never proved, never published, and in my experience rely on poor understanding of background research and scientific rationale.
It’s one thing to have reservations about model projections, and a whole different issue believing scientists are generally not trustworthy and have little integrity – and that it applies only to scientists who support CAGW theory. That’s just not a reasonable, evidence-based stance.

pameladragon

Kristi, you are an idiot! The Hockey Team is as corrupt as they come and giving any of them the benefit of the doubt is foolish. I fail to understand why you continue to troll this website. If I were in charge, you would have been black-listed a long time ago. You add nothing to the conversation, you insist that the rest of us are in error, and you refuse to back down, no matter how many rebuttals you get. This is two martians talking but I do believe I would say the same without their help!

Kristi Silber

pameladragon,
I am not an idiot. I am trying to use reason. I’m admitting I don’t know some things, which to me makes me the opposite of an idiot – idiots don’t know their limitations.
I don’t insist the rest of you are in error. That’s not what I’m trying to get across at all. My main message is that many here are being influenced toward an extremely biased view of things, and they don’t realize it.
I don’t have to imagine some conspiracy, I see the evidence here every day. I don’t think it’s right.
I care about America. There is a terrible gulf between “us” and “them,” and I don’t think it’s healthy for our nation. Nor is it healthy to lose trust in the scientific community. I want to be able to do something about it, and the only way I can think of is to put a seed of skepticism in people’s minds by urging them to be aware l of the ideas they are exposed to, the assumptions and misinterpretations. I don’t do it very well, I guess.
You would have blacklisted me.
Anthony hasn’t, and I appreciate that. It’s a good value. I’m trying to talk to him, too. I would like him to make the site more welcoming to alternative views; the main writers tend to nurture fanaticism through their annotations and comments. But it’s his site, so I don’t really expect to have an influence.
I come here to learn. I follow up, explore the evidence – I read McKitrick, and Willis’s article he submitted. Almost all my knowledge of climate and the debate has been through participating here and at Breitbart…and that has only made me more cognizant of the influences at work, on both sides.
I’m not diplomatic, I know. But I’m not a troll.
And I’m certainly no idiot, pameladragon.

Simon

pameladragon
I thought her response (unlike yours) was quite thoughtful and respectful. Kristi is quite correct I think. Many have tried to disprove the hockey stick all have failed. Yes there were errors, but the basic premise was right. Recent warming is significant. And as you will know Mann’s work has been reproduced many times. Probably the most famous was the work done by BEST. You will remember that was the study skeptics were going to accept irrespective of what it threw up. Up popped another hockey stick and suddenly the BEST team were the enemy.
Anyway all this is kind of irrelevant (although historically interesting) given the earth has shown a steep warming lately, the ice is still melting and the sea is rising.

Good luck with that. What sort of nation puts a guy like Scott Pruitt in charge of the EPA (Environmental Pollution Agency). Probably the most corrupt politician around at the moment.

“Nor is it healthy to lose trust in the scientific community. I want to be able to do something about it”
if that is true, what you can do about it is to stop ignoring and/or defending the malfeasance in the scientific community that has lead to that distrust and start holding those in the scientific community accountable for their actions and insist that pal reviews, gatekeeping, hiding declines, refusing to release data and methods, etc is not acceptable.

Tim F

Kristi; if you do not know the full story then you should stop commenting. Many, many people over the last 20 years have dug deeply into the processes and procedures used by Mann and others. This was not some post-doc mistake. This was deliberate fraud that continue to be propagated and defended by naive and uninformed people such as yourself. These people have hoisted themselves on their petards. The actions over the last 30 years and their words define them as fraudsters who should be prosecuted by their Universities and government funders.

Kristi Silber

Tim F,
You don’t know the full story, either, and you are naive to think you do.
Sure, many have said they’ve found terrible misconduct. But do they also tell you that Mann and co. were trying to address a problem of ethics in the scientific community that involved skeptic scientists? One that ended in the resignation of two journal editors? Or is that an incident that was twisted around to make it look like Mann was silencing skeptics? Have you really looked into it?
I’m not here to defend Mann. I’m sick of people using this incident as an excuse to say science is full of fraud.
[???? .mod]

MarkW

Kristi, there you go again.
Nobody uses this one incident as proof that the science is a fraud.
We have hundreds of examples that prove that.

John Endicott

“this incident”, while certainly the most (in)famous, is merely the tip of the corrupt iceberg.

Kristi Silber wrote, “Mann and co. were trying to address a problem of ethics in the scientific community that involved skeptic scientists? One that ended in the resignation of two journal editors?”
The problem wasn’t ethics, the problem was apostasy.
In 2003, after Soon and Baliunas published a skeptical paper, Mann sought retribution against them, and against the journal editors who allowed their paper to be published.
Then, in 2005, McIntyre & McKitrick published “the paper that busted Mann’s Hockey Stick,” Hockey Sticks, Principal Components and Spurious Significance, Geophysical Research Letters, Vol. 32, No. 3, L03710. doi:10.1029/2004GL021750.
Here Wigley says if GRL Editor James Saiers is a skeptic they should get him ousted:
http://www.sealevel.info/FOIA/1106322460.txt
After Saiers stepped down, Mann says the GRL “leak” is “plugged.”
http://www.sealevel.info/FOIA/1132094873.txt

Michael Mann also demonstrated his concern for ethics with his praise for Fakegate forger Dr. Peter Gleick, whom Mann recently called “one of the most respected scientists in the country.” Here’s Mann’s tweet:

Note: if you can’t view Mann’s tweet because he’s blocked you on Twitter, then right-click the link and “open link in incognito window” or “open link in new private window” or “open in new InPrivate window,” or similar.

Kristi, as usual you are long on accusations and short on links, facts, names, support, or anything to back up your accusations.
I assume you are talking about the case of Chris de Freitas. For those who are interested in facts rather than your puerile claims, you can read about it here.
Of course, given the typically fact-free nature of your vapid attack, you may be talking about something else entirely …
w.

Kristi Silber

Willis, I’ve tried to be civil to you. At one point I even enjoyed exchanges with you. But your continued “puerile” insults of me are wearing thin. You are a bully.
I’ve been reading the climategate emails.
Then I go to the link you give me. There’s an excerpt, then, “The first point to note is their concern is as much about the impact upon policy as it is about the science.”
THIS is the reason I have so little respect for your movement. You people can’t keep politics out of science, and you attribute political motives to scientists in order to cast doubt on the integrity of their research. It’s reprehensible.
As I said, I have been reading the emails. I find this group of scientists talking about the purity of science, the quality of science. They believe it’s their professional duty to be whistleblowers. It’s not something they wanted to do. It’s interesting seeing these others on the same subject, but a different subset. They are interpreted in ways that are simply irresponsible, biased, imaginative, and meaningless. Read the emails, not the interpretations. Read them as typed, without the stress added. You probably have, and you want to see in them evil designs. Reason will get me nowhere because you are so filled with anger, or whatever it is, I don’t know.
I read your whole email interaction about the FOIAs, too. I want to find out if skeptic complaints are justified. Still looking.
I don’t give a d— what you think about me, so you can insult me all you want – it just shows me the kind of person you are.

DaleC

Kristi, you keep deferring to the eight enquiries. As Judith Curry said (as best I recall) the enquiries were like calling the fire brigade because your house is on fire, but they look only in the basement, assert ‘no fire here’ and leave you to it. The various enquiries were Yes Minister parodies – seems impossible, I know, but that’s what we have. For a complete forensic deconstruction, see
https://www.thegwpf.org/images/stories/gwpf-reports/Climategate-Inquiries.pdf

Kristi Silber

DaleC,
Do you really believe that report is going to give an accurate assessment of the depth of the investigations? See, that’s a problem right there. If you can’t identify the sources of bias and learn to be SKEPTICAL of THEM, you will never find the truth.

John Endicott

” If you can’t identify the sources of bias and learn to be SKEPTICAL of THEM, you will never find the truth”
Says the person showing a complete lack of skepticism over the entire issue. Try practicing what you preach sister

John Endicott

And another thing, being skeptical of a source of bias does not require dismissing the message as you do – that’s attacking the messenger because you can’t handle the message. Everyone has biases, even Mr Mann whom you are rushing to defend like a white knight. Having a bias does not necessarily mean ones message is wrong. One should evaluate the message based on its merits or lack thereof something you clearly have shown you don’t do.

MarkW

Kristi, once again you make the assumption that those who disagree with you are either incompetent or evil.
Those of us who graduated more than a year or two ago, have actually read the entire report of the investigations and have reached our conclusions based on all the data.
And yes, the Dale’s summation is accurate.
In one investigation, they interviewed the accused, and when he declared his innocence, they wrapped up the investigation.
They were white washes designed to quickly clear the name of someone who was bringing lots of money into the university.

Reg Nelson

Kristi,
The main British inquiry was asked, by a reporter, about the deleted emails and the the lead investigator admitted that they never asked Jones et al about them. You seem incredibly ignorant on this topic.

Who’s Jones again?

John Endicott

That you are ignorant of who Phil Jones is, speaks volumes of your ignorance on this subject.

Of course I know who Jones is. I was playing the part of the ignorance of which I was accused.
“” If you can’t identify the sources of bias and learn to be SKEPTICAL of THEM, you will never find the truth”
“Says the person showing a complete lack of skepticism over the entire issue. Try practicing what you preach sister”
Baloney. You have no idea what I think. And you aren’t getting it. I’m saying, be aware of the influences on you that are biased, and be skeptical of their message. I’m not hanging out in a playground of bias confirmation. I am challenged by the ideas and evidence of others, and I do not ignore them, I explore them. I know them far better and more thoroughly than I do CAGW arguments.
>>>Most of what I’ve learned about the debate and about skeptics and the skeptic movement has come through interacting with skeptics themselves.<<<
But that has also led me to sites that address influences on skeptics. I can see why emotionally people are reluctant to dig too deep, but from the standpoint of reason and truth-seeking people should know how others tried to manipulate them. It may not be a coincidence that the messages industry chose to instill 20 years ago are the same ones used by the skeptic community today, despite the advances in science.
Skepticism is good, but if non-experts are going to make a choice, at some point he will have to trust someone on authority. Laymen like me don't have the ability to personally evaluate all the science involved. I trust in the mainstream scientific community partly because I seen no proof that I shouldn't, even after reading plenty of articles saying I should. Whenever I dig deeper, I find that people have twisted words, perverted meanings, and that is reason not to trust the skeptic side. Also, the science of the skeptics is weak. I have reasons as well as bias.
daveburton
Thanks, I'd been reading the emails already.

Chimp

Kristi,
As Feynman famously said, “Science is the belief in the ignorance of experts”. In the case of CACA, it’s actually easy for a layman to know that the Team has got it all wrong. To cite but one readily understood instance, where is their evidence that positive water vapor feedback triples the greenhouse effect of CO2? Without that unphysical, evidence-free assumption, ECS is only around one degree C per doubling of CO2, hence nothing at all about which to be concerned, but welcomed, with the obvious benefits from more plant food in the air.
Had you trusted the experts in 1540, you’d believe that the sun goes around the earth. In 1780 that combustion owes to phlogiston. In 1850 that God made every species and that humors cause disease. In 1900 that earth is only tens of millions of years old and that space and time are absolute and gravity instantaneous. In 1950, that continents don’t drift. In 1980, that bacteria don’t cause ulcers. To name but a few such instances. The consensus is always wrong.

His career has prospered, but posterity will remember him as far more felonious than the perpetrator of the Piltdown Man ho@x.

It really is funny how Kristi can dish it out, but gets so daintily offended when it’s dished back at those she worships.

Louis Hooffstetter

Kristi, please take the time to watch the videos of Steve McIntyre and Richard Mueller, and to review the comments above: The IPCC ‘researchers’ were corrupt. The Climategate emails show they were on a mission to document catastrophic anthropogenic global warming (CAGW). To that end, they conspired to get rid of well documented periods that didn’t support CAGW (the Medieval Warm Period, the Little Ice Age, and the ‘1940’s warm blip’), and to get rid accomplish this they used a questionable proxy (tree growth in response to climate), discarded unsupporting data, and tortured the remaining data using an unreliable variant of PCA to produce the desired result (the now infamous ‘Hockey Stick’ graph). When the original graph wasn’t dramatic enough, they deleted a part of it (that showed an apparent decline in temperatures after ~1960) and spliced historical temperature readings into that section of the PCA. When questioned about their work, they refused to share their data and methods, conspired to their delete data and methods, and additionally conspired to delete their emails if necessary to prevent people from finding out the truth.
These people are NOT scientists in any way, shape, or form. They are corrupt liars who conspired to twist science in an effort to create a false narrative for politicians. That is the definition of a witch doctor.

It’s really funny how MarkW has a fantasy Kristi he likes to talk about who shares so few similarities with me besides a name.
Louis,
I know about the things you mention. I have a different view. The evidence you cite is the same I’ve seen, but without the “skeptic” spin. I’ve read some of the “science” posted at ClimateAudit refuting Mann’s work as well as the work itself.
I don’t claim to be able to assess the science itself, but I find the skeptic work so riddled with policy, advocacy, opinion, and insult that it doesn’t have even the veneer of professionalism.
There is more than enough evidence of incidents of wrongdoing among skeptic scientists to balance those alleged among mainstream scientists. I don’t back up my claims with evidence simply because it takes time and I don’t think it would make any difference. Not to those who are certain their ideas are right.
Don’t make the mistake of thinking I’m ignorant of skeptics’ claims, though.
“Kristi, please take the time to watch the videos of Steve McIntyre and Richard Mueller, WHY? DO THEY HAVE NEW EVIDENCE? and to review the comments above: The IPCC ‘researchers’ were corrupt. SO SOME SAY. IF TRUE, THE WORLD WOULD HAVE RESPONDED. TOO MUCH RIDING ON THIS. The Climategate emails show they were on a mission to document catastrophic anthropogenic global warming (CAGW). To that end, they conspired to get rid of well documented periods that didn’t support CAGW (the Medieval Warm Period, the Little Ice Age, and the ‘1940’s warm blip’), THOSE ARE ACKNOWLEDGED; THEY MAKE NO DIFFERENCE TO CAGW. DO YOU MEAN MANN’S COMMENT ABOUT “CONTAIN”? CITE THE EMAILS and to get rid accomplish this they used a questionable proxy (tree growth in response to climate), TREE RING, ICE CORES, ICE MELT, EXTENDED RECORD discarded unsupporting data, ??? and tortured the remaining data using an unreliable variant of PCA to produce the desired result (the now infamous ‘Hockey Stick’ graph) I’M NOT CONVINCED EITHER WAY ABOUT THIS . When the original graph wasn’t dramatic enough, they deleted a part of it (that showed an apparent decline in temperatures after ~1960) THIS WAS LEGITIMATE. THE DECLINE HAD ALREADY BEEN DOCUMENTED ELSEWHERE AS A WIDESPREAD ARTIFACT, AND WASN’T PRESENT IN THE INSTRUMENTAL RECORD. THE PROBLEMS WERE, AS I UNDERSTAND IT, IN THE IPCC GRAPH, NOT THE ORIGINAL PUBLICATION and spliced historical temperature readings into that section of the PCA. When questioned about their work, they refused to share their data and methods, conspired to their delete data and methods, and additionally conspired to delete their emails if necessary to prevent people from finding out the truth.” THE FOIA RESPONSES WERE UNPROFESSIONAL, TRUE, AND IT DOESN’T EXONERATE CRU TO NOTE THAT THE REQUESTS WERE SOMETIMES UNPROFESSIONAL AS WELL. FOR EXAMPLE, MULTIPLE PEOPLE FROM CLIMATEAUDIT WERE MAKING FOIA REQUESTS AT THE SAME TIME, AND THERE IS NO JUSTIFICATION FOR THAT. CRU FELT IT WAS HARASSMENT.
STILL, I’M NOT DEFENDING CRU, MANN OR ANYONE ELSE, I’M JUST TRYING TO SEE THIS RATIONALLY AND SHOW ANOTHER SIDE TO THE STORY. People started saying I was defending Mann before I said anything about him! I don’t even really like the guy.
NorwegianSkeptic,
I know the scientific method. I also know there are plenty of variations on the standard scientific method that are valid. The methodology – the philosophy and reasoning behind the methods – is more important than the method per se.
Experimental design and use of the correct statistics are vital.
Models have long been standard, accepted scientific tools. Tree ring interpretation is not straightforward, but it, too, is an accepted tool.
What’s your point?

Chimp

Kristi,
Yes, it is reasonable to blame the mendacious, rent-seeking, nest-feathering, trough-feeding, cr!minal CACA Team of charlatans for the squandering of trillions in treasure and millions, if not tens of millions, of lives. Not to mention the massacre of billions of birds and bats.

[in reply to Louis Hooffstetter pleading, “Kristi, please take the time to watch the videos of Steve McIntyre and Richard Mueller”] Kristi wrote, “WHY? DO THEY HAVE NEW EVIDENCE?”
Yes, some of what they explain will almost certainly be “new evidence” to you.

Chimp – what will you say if it does get warmer? They broke the rules of collaboration and cross checking in science so I guess it doesn’t matter.

Chimp

Meteorologist,
The gatekeepers will make sure that it keeps warming in their cooked books for as long as possible. But eventually Mama Gaia will have her say.
If in objective physical reality, however, it does indeed keep (or start) warming relentlessly for the rest of the century, as in the GIGO models, then I’ll have to say I was wrong. But I’m unlikely to make it past 2050, when I would turn 100.
If I’m still alive in 20 years however, and Earth in reality has warmed since now until then, I’d say that I was wrong.

As I recall when Mc &Mc broke the scandal, they had an approximation of Mann’s “model”. Also recall, that even random numbers entered would produce a “Hockey Stick”, which is mentioned in an above post.
The chuckle I get when describing the offense to science is that “Even if you put in baseball scores the ‘model’ would print a ‘Hockey Stick'”.

Too bad the climate crowd didn’t heed this sign twenty years ago when Mann published his hockey stick! “Mann Road – Dead End” (sarc – spotted sign in southern Oregon).

Hoax,
Some people fall for a hoax.
Some people like a hoax if they can make money off of it. The hoax was not only Michael Mann’s hockey stick but the whole climate change CO2 global warming theory.
When the hoax allows people to keep making money, decades later, they continue to propaganize it in as many ways as possible to keep the income going.
Eventually, human nature results in “believers” and the hoax gets bigger and bigger and becomes a following that includes lots of people and involves lots of money.
One day, as much as centuries later, the hoax eventually dies or the worst result happens, in that it continues to grow into a religion.
The final story is still not told yet. Your grandchildren may be altar servants in the new following.

Bill,
The difference is that this ho@x is falsifiable, in ways that the Second Coming and other millenarian cults aren’t.
Maybe I’m too optimistic about human nature, but IMO there will come an ignominious end to this ho@x as to eugenics, which wasn’t so much a ho@x as an impaired understanding of natural selection, crossed with various unwarranted prejudices.
But you’re right that it’s a ho@x which has been seized upon by Leftists intent on signalling their virtue.

Still missing comments from two people here………

I have given several skeptical man made climate change presentations to fellow engineers. I show the hockey stick graph early in the presentation and ask if my fellow engineers see something strange in the graph. Runaway man made global warming is well under way by the year 2000. Look at the graph again. We are in the year 2018 and there are no runaway temperatures. That usually convinces engineers that something is not right about the theory. If we engineers had conducted a study and missed a prediction by this much we would hang our heads in shame, not try to make excuses and justify what we had done.

But to be clear, the first anti-science shot across the bow was Ben Santer’s human finger-print attribution fraud he committed in 1995 on the Second AR WG 1 report. He committed his act of scinetific malfeasance after his colleagues had departed the Madrid coordination meeting. That Mr Santer is still drawing government paycheck as a climate modeller is a travesty on all science.
