Hi Phil,
Thanks--we know that. The point is simply that if we want to talk about about a
meaningful "2009" anomaly, every additional month that is available from which to
calculate an annual mean makes the number more credible. We already have this for
GISTEMP, but have been awaiting HadCRU to be able to do a more decisive update of the
status of the disingenuous "globe is cooling" contrarian talking point,

Kevin,
I didn't mean to offend you. But what you said was "we can't account for the lack of warming at the moment". Now you say "we are no where close to knowing where energy is going". In my eyes these are two
different things -- the second relates to our level of understanding,
and I agree that this is still lacking.

I appreciate the responses regarding my concern about the new 'IPCC'
fossil CO2 emissions scenarios. However, no-one seems to be willing to
grasp the nettle and suggest what can be done about it. From what Hugh
says, all scenarios go through the same 2005 value, so this suggests an
obvious 'fix'.
Climate change Deniers hoax themselves … again
November 21, 2009 by greenfyre
I’m going to go out on a short limb here, but frankly more and more it is sounding like the correct response to “Have you seen the emails?” is “Yeah, have you?“
I refer to the uproar about the hacked CRU site which I posted about a few hours ago.
For all the Sturm und Drang and Denier promises of “final coffin nails”, there doesn’t actually seem to be anything to the story. Sure, some impolitic and not nice things got said, and it’s embarrassing for some, but that seems to be about it.
We have all been waiting for the boot, or a shoe, or even a slipper to drop, and so far not even a sock … there’s nothing there. Nada, zilch, gar nichts, mei you. That’s it, there’s no story, go home … get a life.
But read on anyway.
I read the emails as someone who trained as a scientist, but has never had anything to do with climate as a research scientist. Thus I have a sense of the culture of the sciences, but without necessarily having any idea what specifics were being referred to with respect to particular papers and studies. Here is my take on it.
From what I have actually seen it is just “shop talk” taken out of context and nothing more. Very much as if a store clerk said they were going to go “hunt down some customers” and then someone else tried to claim that they were planning a murder. Have you ever said you were going to go “rustle up some grub?” you cattle thief you! Hope you didn’t put it in an email.
Let’s look at a bunch of the “damning” quotes along with climate change Denier Tony Hake’s commentary, and the emphasis he added. Caution, I get frankly rude about the willful convoluted misinterpretations that Hake attempts to impose. It’s dishonest, unethical, and lame.
Dear Phil and Gabi,
I’ve attached a cleaned-up and commented version of the matlab code that I wrote for doing the Mann and Jones (2003) composites. I did this knowing that Phil and I are likely to have to respond to more crap criticisms from the idiots in the near future, so best to clean up the code and provide to some of my close colleagues in case they want to test it, etc. Please feel free to use this code for your own internal purposes, but don’t pass it along where it may get into the hands of the wrong people.
Hake: From Michael E. Mann (witholding of information / data):
1) Computer code is generally proprietary to the institution, NOT information/data;
2) Deniers are notorious for scarfing up drafts etc and releasing them with the claim that they are the final product. Not wanting to release code that is still in testing and potentially flawed (hint “test”) in case some moron doesn’t understand what “in testing” means (the name Hake comes to mind for some reason) is perfectly sensible.
The Korttajarvi record was oriented in the reconstruction in the way that McIntyre said. I took a look at the original reference – the temperature proxy we looked at is x-ray density, which the author interprets to be inversely related to temperature. We had higher values as warmer in the reconstruction, so it looks to me like we got it wrong, unless we decided to reinterpret the record which I don’t remember. Darrell, does this sound right to you?
Hake: From Nick McKay (modifying data):
To “reinterpret” is NOT “modifying data”, it’s analysis (did Hake not even do 1st year college?) Repeating an analysis may be done for any number of reasons and is standard practice. As long as the final result accurately presents the results and describes what was done with them there is no issue whatsoever.
We probably need to say more about this. Land warming since 1980 has been twice the ocean warming — and skeptics might claim that this proves that urban warming is real and important.
Hake: From Tom Wigley (acknowleding the urban effect):
He is NOT acknowleding (sic) the urban effect. He is acknowledging the
fact that land warms twice as much as ocean, and since there are some morons who understand climate science so poorly they might claim it is an urban effect (the name Hake comes to mind for some reason), there is a need to explain it more fully.
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.
Hake: From Phil Jones (modification of data to hide unwanted results):
1) “Nature trick” to me he is referring to a published technique, ie in the Journal Nature (hence capitalized) … or does Hake think they hide data and then publish the fact? Certainly “trick” is a common synonym for “(clever) technique” in the sciences, and everywhere else.
I do not know the literature well enough to suggest exactly which paper and what technique Jones may have been referring to, but maybe someone else does. Unless Hake is suggesting that maybe Jones meant using blades of grass and song birds for his Nature “trick.”
2) Hake wants us to believe that “hide the decline” refers to temperature … “last 20 years (ie from 1981 onwards.” There was no decline in temperature from 1981 onwards, it was a period of steep warming. We know from other data sets! Why would Jones want to hide a non-existent decline?
3) Turns out the “adding in the real temps” refers to as opposed to the estimates. So what was Jones referring to? I don’t know, but there are many possible legitimate things such as various forms of statistical ‘noise.’
The answer is probably to be found when the full email exchange is reconstructed and/or the technique referred to is identified, but as read there is not necessarily anything nefarious here.
If a reconstructed exchange shows intent to falsify data, fine, but as it appears here it is no more telling than overhearing a co-worker say “I’m going to kill him” without knowing anything about the context. Could be a fussball match or a Tetris wager.
As expected: Mann said the “trick” Jones referred to was placing a chart of proxy temperature records, which ended in 1980, next to a line showing the temperature record collected by instruments from that time onward. “It’s hardly anything you would call a trick,” Mann said, adding that both charts were differentiated and clearly marked.

The warmist conspiracy: the emails that most damn Jones
Andrew Bolt
Saturday, November 21, 2009 at 12:19pm
These are the emails that should have Professor Phil Jones most worried about his future.
Jones, head of the CRU unit whose emails were leaked, has been under most fire so far over one email in particular in which he boasted of using a ‘“trick" to “hide the decline” that would have otherwise spoiled his graph showing temperatures soaring ever-upward.
But far more serious - at least in a legal sense - may be his apparent boasting of destroying data to stop sceptics from checking this alarmist work. If, as some emails suggest, he destroyed it to thwart FOI requests from Professor Ross McKitrick and Steve McIntyre, who’d already exposed as fake the Michael Mann “hockey stick”, Jones, one of the most active of the IPCC lead authors, could even face criminal charges.
(Note: in saying that, I should add that these emails may simply be poorly worded, out of context or even altered by the whistleblower who leaked them. Jones may also not knowingly have done anything wrong, and there is no proof that he did anything against the law. UPDATE: Several updates on Jones below, including his “selfish” wish to see global warming “regardless of the consequences” just to be proved right.)
Whether laws were broken or not, the emails prove beyond doubt how resistant Jones and his colleagues were to having their work properly scrutinised by anyone not of their “team”. No wonder, perhaps, when the documents reveal Jones has so far attracted $25 million in grants.)
The most damning emails on this point are the following, starting with 1107454306.txt, in which Jones refers to MM - McIntyre and McKitrick (bold added):
At 09:41 AM 2/2/2005, Phil Jones wrote:
Mike, 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 send to anyone. Does your similar act in the US force you to respond to enquiries within 20 days? - our does ! The UK works on precedents, so the first request will test it.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. IPR should be relevant here, but I can see me getting into an argument with someone at UEA who’ll say we must adhere to it !
Jones admits he was warned by his own university against deleting data subjected to an FOI request from McIntyre - or anyone:

Ben,
Haven’t got a reply from the FOI person here at UEA. So I’m not entirely confident the numbers are correct. One way of checking would be to look on CA, but I’m not doing that. I did get an email from the FOI person here early yesterday to tell me I shouldn’t be deleting emails - unless this was ‘normal’ deleting to keep emails manageable! McIntyre hasn’t paid his £10, so nothing looks likely to happen re his Data Protection Act email.
Anyway requests have been of three types - observational data, paleo data and who made IPCC changes and why. Keith has got all the latter - and there have been at least 4. We made Susan aware of these - all came from David Holland. According to the FOI Commissioner’s Office, IPCC is an international organization, so is above any national FOI. Even if UEA holds anything about IPCC, we are not obliged to pass it on, unless it has anything to do with our core business - and it doesn’t! I’m sounding like Sir Humphrey here!
Makes you wonder very strongly what Jones is trying to hide, doesn’t it? Also makes you laugh all over again at his claim once that the data being sought had, sadly, been ... um, lost.
In1212063122.txtm, Jones urges another colleague, Michael “Hockey Stick”, Mann, to join in the deleting - at least of emails about the IPCC’s controversial ARA report on man-made warming which Jones co-authored, and which claimed warming was “unequivocal” and “most likely” caused by humans:

Can you delete any emails you may have had with Keith re AR4?
Keith will do likewise. He’s not in at the moment - minor family crisis.
Can you also email Gene and get him to do the same? I don’t have his new email address.
We will be getting Caspar to do likewise.
I see that CA claim they discovered the 1945 problem in the Nature paper!!

PS I’m getting hassled by a couple of people to release the CRU station temperature data.
Don’t any of you three tell anybody that the UK has a Freedom of Information Act !
And when Jones is really forced to the point of handing over his data, he considers ways to may checking it more difficult or annoying:
Options appear to be:
Send them the data
Send them a subset removing station data from some of the countries who made us pay in the normals papers of Hulme et al. (1990s) and also any number that David can remember. This should also omit some other countries like (Australia, NZ, Canada, Antarctica). Also could extract some of the sources that Anders added in (31-38 source codes in J&M 2003). Also should remove many of the early stations that we coded up in the 1980s.
Send them the raw data as is, by reconstructing it from GHCN. How could this be done? Replace all stations where the WMO ID agrees with what is in GHCN. This would be the raw data, but it would annoy them.
But Jones figures a way out:

Climate Depot Reveals Alleged Global Warming Conspiracy
November 21st, 2009 - 6:55 pm ICT by GD
By Ranjan Bhaduri
Nov. 21, (THAINDIAN NEWS) An astonishing article has been posted on a site called Climate Depot, perceived as an anti-global warming website, which states that a bunch of hackers broke into CRU and got away with some emails and documents which can prove, that the whole issue of global warming is just a hoax.
CRU or Climatic research Unit established in East Anglia is among the world’s top research centers. The hacker, reportedly an insider, illegally accessed the Hadley computers at CRU and released around 1079 confidential emails and 72 documents that show the manipulations of the global warming data being master-minded by top-scientists. The emails ultimately claim that “global warming is nothing but an exaggerated hoax”. In response to the whole agenda, there are some reputed experts and scientists who say, that the emails and documents do not in any way point towards a “conspiracy/ hoax/ falsifying data”.
Phil Jones, the director of CRU also reported that, “It was hacked. We were aware of this about three or four days ago that someone had hacked into our system and taken and copied loads of data files and emails.” Jones went on to explain the whole issue when questioned about the email which talks about “hiding the decline”. According to the story posted, the director of the University also says that the e-mails appear as genuine, and several of the emails can be accessed at various sites by netizens.
If proved true, this could be one of the biggest scandal in modern history and would involve the illegal destruction and manipulation of important data. It is also being reported that after the incident, CRU has also canceled all of its existing passwords.
ClimateGate: how the MSM reported the greatest scandal in modern science
By James Delingpole Politics Last updated: November 21st, 2009
Here’s what the Times has had to say on the subject:
(Yep. Nada)
And the Independent:
(Yep. Ditto).
And here’s how The New York Times (aka Pravda) reported it:
Hundreds of private e-mail messages and documents hacked from a computer server at a British university are causing a stir among global warming skeptics, who say they show that climate scientists conspired to overstate the case for a human influence on climate change.
(Yep. That’s right. It has only apparently caused a stir among ’skeptics’. Everyone else can rest easy. Nothing to see here.)
And here’s how the Guardian has reported it:
Hundreds of private emails and documents allegedly exchanged between some of the world’s leading climate scientists during the past 13 years have been stolen by hackers and leaked online, it emerged today.
The computer files were apparently accessed earlier this week from servers at the University of East Anglia’s Climate Research Unit, a world-renowned centre focused on the study of natural and anthropogenic climate change.
(Oh. I get it. It’s just a routine data-theft story, not a scandal. And a chance to remind us of the CRU’s integrity and respectability. And – see below – to get in a snarky, ‘let’s have a dig at the deniers’ quote from Greenpeace).
A spokesman for Greenpeace said: “If you looked through any organisation’s emails from the last 10 years you’d find something that would raise a few eyebrows. Contrary to what the sceptics claim, the Royal Society, the US National Academy of Sciences, Nasa and the world’s leading atmospheric scientists are not the agents of a clandestine global movement against the truth. This stuff might drive some web traffic, but so does David Icke.”
Here’s the Washington Post:
Hackers broke into the electronic files of one of the world’s foremost climate research centers this week and posted an array of e-mails in which prominent scientists engaged in a blunt discussion of global warming research and disparaged climate-change skeptics.
The skeptics have seized upon e-mails stolen from the Climatic Research Unit of the University of East Anglia in Britain as evidence that scientific data have been rigged to make it appear as if humans are causing global warming. The researchers, however, say the e-mails have been taken out of context and merely reflect an honest exchange of ideas.
(Ah, so what the story is really about is ’skeptics’ causing trouble. Note how as high as the second par the researchers are allowed by the reporter to get in their insta-rebuttal, lest we get the impression that the scandal in any way reflects badly on them).
Here is the BBC:
E-mails reportedly from the University of East Anglia’s Climatic Research Unit (CRU), including personal exchanges, appeared on the internet on Thursday.
A university spokesman confirmed the email system had been hacked and that information was taken and published without permission.
An investigation was underway and the police had been informed, he added.
(Ah yes, another routine data-theft story so dully reported – “the police had been informed, he added” – that you can’t even be bothered to reach the end to find out what information was stolen).
Meanwhile, the ClimateGate scandal (and I do apologise for calling it that, but that’s how the internet works: you need obvious, instantly memorable, event-specific search terms) continues to set the Blogosphere ablaze.
For links to all the latest updates on this, I recommend Marc Morano’s invaluable Climate Depot site.
And if you want to read those potentially incriminating emails in full, go to An Elegant Chaos org where they have all been posted in searchable form.
Like the Telegraph’s MPs’ expenses scandal, this is the gift that goes on giving. It won’t, unfortunately, derail Copenhagen (too many vested interests involved) or cause any of our many political parties to start talking sense on “Climate change”. But what it does demonstrate is the growing level of public scepticism towards Al Gore’s Anthropogenic Global Warming theory. That’s why, for example, this story is the single most read item on today’s Telegraph website.
What it also demonstrates – as my dear chum Dan Hannan so frequently and rightly argues – is the growing power of the Blogosphere and the decreasing relevance of the Mainstream Media (MSM).
This is not altogether the MSM’s fault. Partly it is just the way of things that more and more readers prefer their news and opinion served up in snappier, less reverent, more digestible and instant for.
But in the case of “Climate Change”, the MSM has been caught with its trousers down. The reason it has been so ill-equipped to report on this scandal is because almost all of its Environmental Correspondents and Environmental Editors are parti pris members of the Climate-Fear Promotion lobby. Most of their contacts (and information sources) work for biased lobby groups like Greenpeace and the WWF, or conspicuously pro-AGW government departments and Quangos such as the Carbon Trust. How can they bring themselves to report on skullduggery at Hadley Centre when the scientists involved are the very ones whose work they have done most to champion and whose pro-AGW views they share?
As Upton Sinclair once said:
“It is difficult to get a man to understand something when his job depends on not understanding it.”
So don’t expect this scandal to be written up in the MSM any time soon. But why would you want to anyway? It’s all here, where the free spirits and independent thinkers are, on the Blogosphere.

I think the scientists are talking about a "trick" but this isn't reliable.
The whole matter comes from these measurements.

I would immediately delete anything you receive from this fraud.
You've probably seen now the paper by Wahl and Ammann which independently exposes
McIntyre and McKitrick for what it is--pure crap. Of course, we've already done this on
"RealClimate", but Wahl and Ammann is peer-reviewed and independent of us. I've attached
it in case you haven't seen (please don't pass it along to others yet). It should be in

Mike,
FYI. Just in for an hour or so today as still off until Jan 4.
Not replied to this - too much else with IPCC etc. Not read this
in detail - just printed it off.
Have a good New Year's Eve.
Cheers
Phil

Dear Phil,
I have noticed the following statements in Rutherford et al [2004], in which you are a
co-author. As compared with some of your co-authors, I get the impression that, while
you feel very strongly about your views, you are also concerned with getting to the
bottom of matters and are less concerned with scoring meaningless debating points. In
this spirit, I draw your attention to some incorrect statements in Rutherford et al.
[2004] concerning our material. There is really a quite serious problem with the PC
methods in MBH98 and the comments made in Rutherford et al [2004] are really quite
misleading. For the reasons set out below, I request that these comments be removed from
the manuscript.
Regards, Steve McIntyre

Dear Dr. Randall,
Recently, at the website [7]www.realclimate.org, Michael Mann publicized a submission by
Rutherford et al. to Journal of Climate, entitled Proxy-based Northern Hemisphere
Surface Temperature Reconstructions: Sensitivity to Method, Predictor Network, Target
Season, and Target Domain. This paper contains some untrue statements and
mischaracterizations regarding criticisms we (McIntyre and McKitrick) made of Mann et
al. (1998) [MBH98] in a 2003 paper and subsequent exchanges under the auspices of
Nature. We are writing to request that these untrue statements be removed from the paper
before any further processing of the document by Journal of Climate takes place.
First, Rutherford et al. states that McIntyre and McKitrick [2003] used an incorrect
version of the Mann et al. (1998) proxy indicator dataset. The history of this matter is
summarized below (all relevant emails and other documentation are available at
[8]http://www.climate2003.com/file.issues.htm .
In April 2003, we requested from Mann the FTP location of the dataset used in MBH98.
Mann advised me that he was unable to recall the location of this dataset and referred
the request to Rutherford. Rutherford eventually directed us to a file (pcproxy.txt)
located at a URL at Manns FTP site. In using this data file, we noticed numerous
problems with it, not least with the principal component series. We sought specific
confirmation from Mann that this dataset was the one used in MBH98; Mann said that he
was too busy to respond to this or any other inquiry. Because of the many problems in
this data set, we undertook a complete new re-collation of the data, using the list of
data sources in the SI to MBH98 and using original archived versions wherever possible.
After publication of McIntyre and McKitrick [2003], Mann said that dataset at his FTP
site to which we had been referred was an incorrect version of the data and that this
version had been prepared especially for me; through a blog, he provided a new URL which
he now claimed to contain the correct data set. The file creation date of the incorrect
version was in 2002, long prior to my first request for data, clearly disproving his
assertion that it was prepared in response to my request. Mann and/or Rutherford then
deleted this incorrect version with its date evidence from his FTP site.
It is false and misleading for Rutherford et al. to now allege that we used the wrong
dataset. We used the dataset they directed us to at their FTP site. More importantly,
for our analysis, to avoid the problems with the principal component series, we
re-collated the tree ring data identified in MBH98 from ITRDB archives, calculated fresh
principal component series; in addition, we re-collated other proxy data from archived
versions wherever possible. Thus, our own calculations were not affected by the errors
in the supplied file as we did NOT use the incorrect version in our calculations. To
suggest otherwise, as is done in Rutherford et al [2004], is highly misleading. To date,
no source code or other evidence has been provided to fully demonstrate that the
incorrect version (now deleted) did not infect some of Manns and Rutherfords other work.
In this respect, we note that the now deleted file pcproxy.txt occurs in a legend in a
graphic at Rutherfords website, indicating possible use elsewhere by Rutherford of the
incorrect version.
Accordingly, we request that the above claim be removed from the manuscript.
Secondly, Rutherford et al. [2004] argues that the difference between MBH98 results and
MM03 results occurs because of our misunderstanding of a stepwise procedure in MBH98 for
the calculation of principal component series for tree ring networks. Again, this claim
is misleading on its face. While our 2003 paper did not implement the (then undisclosed)
stepwise procedure, as soon as this matter was raised in subsequent correspondence in
November 2003, we implemented it and we continued to observe the discrepancies in
principal component series and final results. The current manuscript ignores a refereed
exchange at Nature in which we specifically clarified (in response to a reviewers
question) that we had obtained such results while using the exact stepwise procedure
described in MBH98. Mann is aware of this refereed exchange.
The reason for the difference between our results and MBH98 results is primarily due to
the fact that the tree ring principal component series in MBH98 cannot be replicated
using a conventional principal components method. The MBH98 principal component series
can only be replicated by standardizing on a short segment a procedure nowhere mentioned
in MBH98 and only recently acknowledged in the SI to the Corrigendum of Mann et al.
[Nature 2004] in response to our concerns on the subject expressed to Nature. In
effect, MBH98 did not use a conventional centered PC calculation, but used an uncentered
PC calculation on de-centered data. The impact of this method is the subject of ongoing
controversy, which is well-known to the authors, but the existence of the method in
MBH98 is no longer in doubt. In discussions of PC calculations in 2004 exchanged with
the authors through Nature, we implemented the stepwise procedures of MBH98 referred to
in the present manuscript and demonstrated that important differences remain even with
stepwise procedures, as long as the uncentered and decentered methods of MBH98 are
used. The differences in PC series resulting from using centered and uncentered series
has been fully agreed to by all parties in the Nature exchange, although the parties
continue to disagree on the ultimate effect on final NH temperature calculations.
Accordingly, the discussion in Rutherford et al. [2004] is very in

Accordingly, the discussion in Rutherford et al. [2004] is very incomplete and
misleading in this respect. While we recognize that Mann et al. have argued that they can salvage MBH98-type results using alternative methodologies (e.g. increasing the
number of PC series used in the 1400-1450 period), these salvage efforts are themselves
a matter of controversy and do not validate the claims being put forward in the
Rutherford et al. paper.
Accordingly we ask that this claim also be deleted from the manuscript.

Stephen McIntyre and Ross McKitrick
