Slides from the Michael Mann lecture at Cabot Institute in Bristol

| UPDATE: The slide originals have been found and posted. See link below. It’s identical to Mike’s AGU trick| As promised earlier this week, I’ve gotten my phone connected and have offloaded all of the photos of Dr. Mann’s slide presentation that I took from my vantage point in the front row. I’ve created a gallery of images with some notes about each. As you can see, it is heavy on politics and light on science. The final slide of his lecture, which depicts his daughter and a polar bear where he talks about “children and our future”, I pixelated out to make it unrecognizable as I don’t think children should be used as props.

I think I got most every slide in his presentation, but there may be one or two missing, as I had issues trying to operate the camera and keeping my hearing assistance device functional (I had to hold it at arms length to get a signal, and put it down to get a photo). Slides go from upper left to right, and are in order. Click the first one and you’ll get a slide show applet in a  new window.

I’ll have some commentary about the Q&A session and why I didn’t ask a question, along with some additional photos, a bit later in a separate post.

 

UPDATE: A PDF of all the slide originals presented in Mann’s Rutgers presentation was released by Mann on the Penn State web page here: http://www.meteo.psu.edu/holocene/public_html/Misc/HSCW_Rutgers_Sep12.pdf

These were the slides used in a September 2012 presentation at Rutgers, which were the subject of Steve McIntyre’s breakdown of the presentation Mann gave to AGU in December 2012 which he called “Mike’s AGU Trick“. At issue was the staleness of temperature data presented which completely eliminates any hint of “the pause”, as seen below.  Mann’s talk in Bristol was the virtually identical set of slides. He hasn’t updated them with anything of significance in 2 years, except for some news headline articles about severe weather events. The data truncated at 2005 has not changed. (h/t to Jean S.)

Excerpt from “Mike’s AGU Trick“:

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

There were two components to Mann’s AGU trick. First, as in Mann and Kump, Mann compared model projections for land-and-ocean to observations for land-only. In addition, like Santer et al 2008, Mann failed to incorporate up-to-date data for his comparison. The staleness of Mann’s temperature data in his AGU presentation was really quite remarkable: the temperature data in Mann’s presentation (December 2012) ended in 2005! Obviously, in the past (notably MBH98 and MBH99), Mann used the most recent (even monthly data) when it was to his advantage. So the failure to use up-to-date data in his AGU presentation is really quite conspicuous.

Had Mann shown a comparison of Hansen’s Scenario B to up-to-date Land-and-Ocean observational data, the discrepancy would have been evident to the AGU audience, as shown in the loop below.

mann-agu-loop-loti

Update: As reader DGH observed in a comment below, Mann’s presentation at Rutgers also employed Mann’s AGU Trick to hide the divergence between Hansen Scenario B and observed temperature, not showing data after 2005. As noted above, not using up-to-date data in virtually identical circumstances was characterized by Pierrehumbert as “ugly” and “illegitimate”:

As reader ZT pointed out, Mann also used his AGU Trick to hide the divergence in his TEDx talk

Amazing actually! Their boat is swamped with irrefutable observational data which contradicts basically all of their predictions and computer models from the past 20 years. But it seems that Captain Mann plans to go down with the ship.

It looks like his Hansen 1988 prediction to temp charts ised the same trick he used at Rutgers and at AGU 2012. McIntyre called him on it then. Hard to be certain given image quality, but looks just like the Rutgers slide, even the black background. Land only temps from GISS rather than land plus sea, truncated at 2005 to hide the pause. In fall 2012, Hansen had GISS land plus sea temps available through mid 2012.

rabbit, this is not a movie theater.
The first question I would ask is: who pays the freight? It seems that Mann has been riding the taxpayer gravy train for a long time. He doesn’t work for a private corporation.
As a taxpayer, I expect to have access to his work product.
Otherwise, I want a refund.

Just telling you the law. Both a presentation and a film are covered by copyright. Just because someone gives a public showing doesn’t mean they are ceding the right to reproduce.
And your argument about “who pays the freight” doesn’t hold up in law. Both professors and universities are allowed to hold copyright, even when funded on the public dime.

rabbit,
Are you a lawyer? If so, what’s your opinion on fair use? Where is the line drawn? These slides were just a small part of the presentation. Mann’s presentation was not recorded.
Of course, if you’re not a lawyer…

Reproducing 80 or more slides likely goes far beyond fair use.
And no, I’m not a lawyer, but that does not stop someone from knowing something of the law, just as you don’t need a degree in climatology to know something about climate. I was an R&D manager for many years, and it was part of my job to understand the basics of intellectual property law. People have been stopped from photographing my presentations due to copyright violation (don’t blame me, I wasn’t the one doing the stopping).
Nor am I claiming I am definitely right in this matter — only a judge can decide that — but I think it would almost certainly raise concerns with lawyers.
I know why you’re putting up these arguments. You don’t like the idea that Watts may have pulled a no-no. Neither do I.

Who said I think it was a ‘no-no’? I don’t. I’m fine with it. If showing slides that were a small part of a presentation isn’t fair use, what is? Mann didn’t complain, and clearly he expected it. He never said not to post anything, he even said he expected pics of his daughter to be used.
You don’t like it. I get that. The tone of your comments is hard to miss.

@rabbit:
Here’s the advice from the UK Intellectual Property Office. This article is non-commercial research, it was necessary to use the amount that was taken, and the work reproduced is supported by a sufficient acknowledgment.
Although the extract seems quite long, a shorter extract would not have achieved the objective of demonstrating the content of this lecture fairly. And the slides are only a small part of Dr Mann’s performance. So I don’t see the problem.
“You are allowed to take short extracts of works when the use is for research that you do not make any money from or for private study, for educational courses or even for use in connection with a hobby. Such use is only permitted when it is ‘fair dealing’ (discussed below).
The purpose of this exception is to provide students and non-commercial researchers more access to copyright works. In assessing whether your use of the work is permitted or not you must assess if there is any financial impact on the copyright owner because of your use. Where the impact is not significant, the use may be acceptable.
If your use is for non-commercial research you must ensure that the work you reproduce is supported by a sufficient acknowledgment.”
http://www.ipo.gov.uk/types/copy/c-other/c-exception/c-exception-research.htm
“Factors that have been identified by the courts as relevant in determining whether a particular dealing with a work is fair include:
* Does using the work affect the market for the original work? If a use of a work acts as a substitute for it, causing the owner to lose revenue, then it is not likely to be fair.
* Is the amount of the work taken reasonable and appropriate? Was it necessary to use the amount that was taken? Usually only part of a work may be used.”

If the slides and presentation were developed and assembled using government money, it is highly unlikely that the individual could claim copyright. It becomes public property, and public knowledge. If anyone should be interested in charging a fee, it is the US government, not Mann.

Nice theory, but it doesn’t work that way. Here’s a link…

Mann’s last slide -picture of his daughter and a polar bear at the zoo. I’ve pixelated it because I don’t think children should be used as props.
If Mann is using his daughter as a prop then the issue is settled no? I too agree with the sentiment but rather than downplay the correct thing is to throw a spotlight on the practice of cute polar bears and “for the children.”
I wish it would not come to this but letting it slide is only going to encourage more.

Exactly. A talk should be pitched at the audience and this was a public lecture. Most members of the public will not have seen the curve. It is arrogant of Watts to think the talk has been tailored for him.

it would appear mann is stuck in the last century and is unaware of the observations of the climate in the last 14 years. i have an ongoing debate with an earth scientist that contributes to sks on another forum,he takes umbrage when i bring up mann as he is apparently no longer relevant in the debate , “that was a long time ago” is the phrase used.
all well and good apart from the fact mann and the cabot institute are still promoting last centuries propaganda.

Hansen maintains his own chart of the 1988 predictions against observations on his personal webpages.
The relevant comparison here is the Blue line (most relevant prediction) against the Black line (GISS land-ocean temps).

I find it interesting that scenario C is actually quite close to observations. I’m assuming that scenario is one in which CO2 emissions cease and there is no additional forcing? If so, it seems we have a model prediction of what would happen if additional CO2 forcing was zero (or very low) that has been started well on its way to being validated by observation.
I tried to find the answer as to what scenario C represents, but his web-site gave me a headache.

IIRC, it was a low end projection through the year 2000, after which temperatures became de-coupled from CO2 (its forcing ceased to be factored in).

Does anyone besides me have a real gripe about “greenhouse effect”? A greenhouse becomes warm and remains warm because convection of heated air is inhibited. Nothing more, nothing less. In the free atmosphere, atmosphere that is heated for whatever reason rises and cools at approximately the adiabatic lapse rate.

Thanks for that! It’s quite interesting that you provided a link to physicist. Yesterday I offered a “Tip/Note” for Anthony here:
http://wattsupwiththat.com/tips-and-notes-2/#comment-1747788

Aside from an article by Willis Eschenbach in 2013, in which he discussed Wood’s experiment and found it inconclusive, I can’t find any articles in WUWT that discuss and follow the timeline of Arrhenius’s GHG hypothesis, its rejection and subsequent acceptance by climate scientists. Many scientists, I presume geologists and physicists still consider it refuted.

I found the geologist and you provided the physicist. I think we’re on a roll.
