Paleoscientist: Mann’s recent work was a ‘crock of xxxx’

From the soon to be a Climate Crock of the Week department, Barry Woods writes to me in an email:

One of the insights in the climategate emails was perhaps how poisonous Michael Mann’s involvement was, for the niche area of the paleo science community (ego due to IPCC and Hockey Stick)?

This tweet from earlier this morning (now deleted, only a text version survives -Anthony) shows the immediate labeling of “denier” for another scientist who disagrees with his paleo work.

Michael E. Mann ‏@MichaelEMann

Closet #climatechange #denier Rob Wilson, comes out of the closet big time: http://www.bishop-hill.net/blog/2013/10/21/wilson-on-millennial-temperature-reconstructions.html … #BadScience #DisingenuousBehavior

Shortly afterwards, Mann got into a long and somewhat huffy discussion with Tamsin Edwards over that labeling, here’s the opening salvo: 

mann_tweet_RobWilson_denier

Also in the feed earlier this morning, (though I can’t find it now) was a Tweet from Mann backing down saying he’d withhold judgment on Rob Wilson until he confirmed those words, suggesting that Andrew Montford (Bishop Hill) had misinterpreted Wilson’s words..

That Tweet apparently has disappeared too. (A WUWT commenter found it, see below, but the original “denier” tweet is still missing -A) I wasn’t going to bother with this article until Dr. Mann started disappearing his own words.

 

Woods continues:

[About the same time] Rob Wilson, had just publicly confirmed (in comments at Bishop Hill) that he thought and had publicly told students, public, etc  Mann’s recent work was a ‘crock of shit’… (his words)

“Lastly, the “crock of xxxx” statement was focussed entirely on recent work By Michael Mann w.r.t. hypothesised missing rings in tree-ring records (a whole bunch of papers listed below).

Although a rather flippant statement, I stand by it and Mann is well aware of my criticisms (privately and through the peer reviewed literature) of his recent work.

==================================================================

Greetings.

Although I vetted Andrew’s post, I want to clarify that my 2 hour lecture was, I hope, a critical look at all of the northern hemispheric reconstructions of past temperature to date. It was not focussed entirely on Michael Mann’s work. I described each of the major studies and tried to highlight both their strengths and weaknesses – they all have some useful information but it is important to understand the limitations of the studies as well. Of course Mann’s work was mentioned as several of his papers have been so prominent over the last 15 years but I actually spent substantially more time taking apart the D’Arrigo et al. (2006) study on which I did much of the analysis.

This was a session where I wanted the students to critically look at the different studies and specifically address what we can learn from them and how the science can move on over the next decade. Such large scale reconstructions are critically important for understanding the controls on large climate variability, but as yet, due to great uncertainties and large differences in reconstructed amplitude, they are not yet very useful at constraining modelled estimates of future temperature change.

Bar some personal comments, much of what I said is published (see papers below) and is in the public domain.

Lastly, the “crock of xxxx” statement was focussed entirely on recent work By Michael Mann w.r.t. hypothesised missing rings in tree-ring records (a whole bunch of papers listed below). Although a rather flippant statement, I stand by it and Mann is well aware of my criticisms (privately and through the peer reviewed literature) of his recent work.

==================================================================

It seems that Rob Wilson has some serious basis for the claim, and he’s sticking by it.

Ross McKitrick sums it up pretty well in a comment:

==================================================================

Mann’s tweet just reveals openly what has long been his working assumption. To Mann, a “skeptic” is anyone who doesn’t accept his work uncritically, and a “denier” is anyone who actually disagrees with him.

It seems he is well qualified to spot paleo-crocks:

=====================================================================

Update: In case anyone doubts the “poisonous” nature of the rhetoric Dr. Mann uses, I’ll point out what he has begun labeling an Virginia Attorney General Ken Cuccinelli, who wanted to look at Mann’s UVA emails under FOIA.

The definition of the slang word “cooch” is:

cooch_def

Source: http://onlineslangdictionary.com/meaning-definition-of/cooch

What a terrible misogynistic label to apply to somebody. You’d think with the recent sexual harassment scandal over Scientific American’s Bora Zivkovic and his actions, Dr. Mann would be a bit more reserved in such nasty labeling.

My advice to Dr. Mann: When you’ve tweeted yourself into a hole, stop tweeting.

Prior to this I’d always thought that being on pot was a lifestyle choice.
I now realise that it’s a fair, albeit scatalogical thumbs-down to post-normal BS!

So we’ve moved on from missing heat to missing tree rings? Is the overall new narrative going to be all about missing things?

Nip is short for nipple of course.
>>>>>>>>>>>>>>>
That thought occurred to me. That said, it was 20+ years ago. It was a greasy spoon diner across from the hotel I was in. If memory serves (and it frequently doesn’t) it was Austin. The manager came out and asked me to leave, so I did. I was too embarrassed to ask anyone, and actually forgot all about it until just now.

October 21, 2013 5:50 pm

I think that after Mann sued Mark Steyn et all for comparing him to a sex pervert he damages his case by tweeting sexually abusive language.

MinB says:
“Not sure what Nip means in Texas, but growing up in CA it was a derogatory word for a person of Japanese (i.e., Nippon) descent. Chink was used similarly for Chinese, Gook for Vietnamese.”
I believe gook was used for Koreans originally. The story goes that the Korean word for Americans which is Miguk was heard by the Marines. As they kept hearing Koreans speak the word they took it as a self description.

And what would nonce like M.Mann know about cooch ?

Note the double-double entendre in Mann’s original tweet. We have “out of the closet” and “denier” all in less than 140 characters (not that I consider either attribute to be a negative per se).
Nice guy.

Something tells me that Mann’s nomadic academic career is no accident. I also bet that he is invited to a lot of parties as a first time guest, but very seldom as a repeat guest.

The term “gook” to refer to locals is attested among Marines during & after the Spanish-American War in the Philippines. Its etymology is obscure. It was later applied to Nicaraguans & Haitians during the Banana Wars.
Still, “American” in Korean, transliterated as “Miguk” or “Migug” is a plausible etymology, although the final consonant is almost silent when spoken. One name for Korea in Korean is “Hanguk/g”.

Luke Warmist: “Is the overall new narrative going to be all about missing things?”
Always has been. It started from the absence of an ice age and has progressed to the absence of the absence of ice. They might have found this instructive, but the Wizard of Oz happens to be absent as well.

Let’s see, you berate Mann for calling Wilson a denier, but cheer Wilson for saying Mann’s work is shit. Doesn’t that seem a bit inconsistent? I am not defending Mann’s tweet, but Wilson’s comments are hardly the epitome of professionalism.

Does Mann actually do any real work or does he spend all his time being a raging A-hole on social media? How much are the taxpayers of Pennsylvania spending on a person that seems to do little work & the work that he does do is shoddy at best?

Not from the pov of truth, if Mann’s work is inaccurate, he should be called on it and that’s what is happening afaics.

One attacks the (a) person, the other attacks the quality of work.
A subtle, but distinct difference.

Dr. Edwards doesn’t need to “lecture” Mann about his tone; it is abundantly clear that his tone is more appropriate to an NFL defensive back on amphetamines and steroids.

In Winnipeg, Manitoba, Canada, there is a restaurant chain known as Salisbury House. They serve what are called “Nips”. This is a hamburger. Salisbury House is a 24 hour diner where breakfast is served all day. People in England often go for a “curry” after an evening at the pub. In Winnipeg, after a night in the bar, people would head to “Sals”.
The “Cheese Nip” is quite a good burger, as it is served plain (no condiments), yet has caramelized onions and real aged cheddar cheese, and the bun is warmed on top of the onions, cheese, and patty while they are cooking.
The quality of food from this establishment is hotly debated amongst Winnipegers, but at 3:30am, it is rarely refused.

Sorry, but you are a bit detached from reality here; you need to get more outside and see what the other kids are doing in the non-climate world.
The ‘Cooch’ is widely and casually called that, with no intent to associate him with any female private parts. E.g. I have just seen a The Young Turks clip where the host Cenk calls him Cooch short for his name, obviously in a ‘buddy’-way; that is like calling Bush ‘Dubya’, or calling a Matthew ‘Matt’ – hey, that’s me! Maybe the spelling is a bit unfortunate here, but you got to keep it real and not get your knickers in a twist over everything. Picking something seemingly clever out of a dictionary can still leave you looking stupid if you evidently don’t know what you are talking about 🙂

Dang, looks like someone has borrowed my name!
Re the issue at hand, I think if Wilson had previously discussed it openly with Mann, and had made no headway, it is probably legitimate to bring attention to his view on the work. And yes, he talks about that work, not Mann himself.

“I thought the word was “count”, or is that too upper class?”
The British Peerage was very careful to rename that particular rank (between Duke and Earl) as “Marquess”…….
