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 Mann, Raymond 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

Phil

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. (Note: Try not to click this link now, CA is overloaded. Can’t even get to it myself to mirror it. -A)

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.

Breaking News! Anthony Watts found to have surreptitiously softened criticism of bad reporting by sympathetic news source!
Critique 1: Daily Tech is unresponsive and slow:
“Note from Anthony: When the DailyTech first posted this story and referenced my blog as the source of th compilation, without ever interviewing me or asking me a single question, I told them immediately they had it wrong. Shortly after that I published this ”Update and Caveat” (below) on the original post since they were slow to react. All told it took over 8 hours for Dailytech to make a change to the wording, but by then the genie was out of the bottle.”

Shortly after posting the note about Daily Tech’s reporting, Mr. Watts apparently decided that his criticism was too harsh.
Critique 2: Daily Tech is gracious and cooperative:

BBC have been awful over the last two days – we had a Red “Take Action” severe weather warning for north-west England and south-west England for heavy rain. When the inevitable happened and we had a fatality (a heroic policeman diverting traffic off a busy bridge, which then collapsed with him on it), they had less than 5 minutes on it in their morning broadcast compared to Sky News which devoted practically all their coverage to the dreadful flooding.
Of course they are now talking about it as a 1-in-1000 year event which all their usual connotations, wry looks to the camera.

Insurgent, good, but how about this one:

I presume congratulations are in order – so congrats etc ! 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 sendto anyone. … We also have a data protection act, which I will hide behind. Tom Wigley has sent me a worried email when he heard about it – thought people could ask him for his model code. He has retired officially from UEA so he can hide behind that.

” Ric Werme (14:35:30) :
I have no problem with the word “trick” – I use many “Tricks of the Trade” to diagnose problems, find workarounds for recalcitrant computers, etc. I have lots of problems with the word “hide” and can’t think of many places in a professional position where hide is good other than military and similar fields.
Congrats to John Finn and others who worked on this years ago. Good job!”
Reminds me of the other usage of “hide”

Tan me hide when I’m dead
So we tanned his hide when he died Clyde
And that’s it hanging on the shed.”

“no mention of the leak on the home page of CNN.com, MSNBC.com, ABCnews”
Last time I looked at the ratings Fox draws more audience in most time slots than all the others combined. So it doesn’t really matter if the other nets aren’t carrying it. Nobody is listening to them preach anyway except the chior.

Very very difficult to get any messages through to our Gav. Hope you are reading lovely boy.
The whole stinking lie is now shown to be a smell. I always thought it was peculier that scientists’ would you use the word denier but now understand that none of you are scientists and your attacks were to hide the fraud.
Not only do you promote a falsehood you conspired together to do so.

geo (14:21:09) asks “If Jones had written ‘address the divergence problem’ instead of ‘hide the decline’ would we be talking about that email at al?”
Yes we would! We would be asking why the tree ring data diverged from the insterment data. We would ask where the insterments where located in relation to the trees. We would question whether the reconstruction was valid through its entirety. We would talk about this e-mail!

geo (15:15:37) :

Btw, since one (unproven) theory is that warming causes “the divergence problem”, has any of the dendros (or Steve McI, should “somehow” the warmists not find it a worthy exercise) taken the observed post-1960s divergence and applied it to the MWP in the reconstructions covering that period? Could, in fact, this be a reason why the warmists have consistently underestimated the MWP?

Um, no, you misunderstand the divergence problem. I shall explain…
The tree-rings are being used, after a sort of weighted average, to determine temperature. The divergence problem is simply the fact that post 1960 or so, many of the tree-rings no longer correlate well to temperature. This implies that tree-rings do not actually respond well to temperature, or at least, temperature is not adequately reflected in their measurement. This cannot be “applied to the MWP” as it signifies the two things (temperature and growth) are uncorrelated (or weakly correlated at best, with a non-linear relationship).
What makes this devastating is that they cannot use reconstructions based on tree-rings to “make the MWP go away.” True, the likes of Mann and others continue to use tree-rings in their reconstructions unabashed, but no amount of screaming can overcome the fact that such reconstructions are worthless.

The leak will only help if it is widely reported. If the MSM refuses to report the leak, the general uninformed population will never hear about it and will still follow Gore.

Trust me Doug, the sheeple, as we are sometimes rather cutely described, are quite capable of seeking out the information they need in order to inform their opinions. Over the last year or so, I’ve seen the comment sections of MSN pro-AGW arguments full to overflowing with sceptic opinions. This isn’t some coordinated attack; it’s ordinary people like you and I proactively informing themselves, raising eyebrows, expressing their views. The days of media mind control over the general population are long gone.

I saw it on FoxNews.com. I e-mailed my Senetors and Congressman because they’re going to see some nutty climate bill and need to be prepared to fight me off when I storm Washington.

This all excellent work.
Here’s what I see as especially ugly and of very low ethical standard:
The emails show very clear how the peer-review process was manipulated, a closed shop for insiders only, and having this neatly organized then arrogantly tell the world that the work of Steve McIntyre a.o. has no value, because not “peer-reviewed”. What a misuse.
What kind of personality must one have to arrange such, proceed and “refine” over years?
And all this fraud is done with taxpayers money? And those people influence politician, media and scare the rest of the world?
Isn’t it about time tha a lot of members in these circles draw a line and get back on track before it’s too late? Come on guys, we’ve got you.

What is the correct solution to this scandal? If the institutes of higher learning are honest, they should fire all those who are involved. Jones, Mann etal. Wanna bet they keep their jobs? This makes these institutes co-conspirators.

Thanks for the comments _________/________. Just wanted to let you know that I’ve dropped the uncertainty ranges to be consistent with the other records and also cut the borehole series at the median sampling dates.

Nevertheless, we had the chance to cross paths today and discuss the figure and caption. We hope it is not too late to add our two cents. We agree that the uncertainties on the borehole curves should be removed to make the
display more consistent. We have also decided that it would be best to truncate the borehole curves at their median logging dates. For Australia and Africa those years are 1972 and 1986, respectively. If you wish to discuss the sampling densities, the total number of boreholes in Australia and Africa are 57 and 92, respectively. The SH has a total of 165 holes, compared to 695 in the NH. Let us know if you need anything else. I hope this has not arrived too late and good luck with everything.

I posted the following at RC as they don’t seem to be censoring everything just at the moment (it’s a credibility thing . . . )
I think the defence of the use of the word ‘trick’ looks a bit like this ploy:
“When I use a word,” Humpty Dumpty said, in rather a scornful tone, “it means just what I choose it to mean—neither more nor less.”
“The question is, ” said Alice, “whether you can make words mean so many different things.”

Re getting this to the mass media, I posted the following on the enormous ‘Breaking News’ thread last night. Since it doubtless got buried, I’m taking the liberty of reposting:

It’s nice that someone has dropped a big comb of honey onto this ants’ nest. But all of the inside chatter in these emails, revealing though it may be to those lapping it up, won’t mean a thing to the average news reporter, media outlet, and the public in general.
What’s needed is a panel of unimpeachable individuals (i.e. no one named in this data drop) who can go through the file, vouch for its authenticity, and issue a quick white paper explaining its implications.
The media are clueless. They need to be helped to understand the significance of—

The “Nature trick” is not near as damning as some of the things about a deliberate attempt to hinder FOI requests. I am sorry, but, if your data and method cannot be reproduced it is not science. Therefore anything that somes from that supposed data and method is meaningless garbage. It is hard to believe those at the Hadley Centre and elsewhere who have blocked these attempts could pass a high school science class with so poor an understanding of scientific method.
Meanwhile the Guardian has published a ridiculous and embarassing article.
http://www.guardian.co.uk/environment/2009/nov/20/climate-sceptics-hackers-leaked-emails
It is obviously nothing but a spin control piece calling for the punishment of the leakers, reminding us of the supposed “evidence for global warming” and deliberately avoiding or oblivious to the entire actual issues. Such as the fact that the evidence they point to is shown by these very documents to have been largely fake.
I still can’t believe these emails can be real.
