But they _shouldn’t._ If two different methodologies applied to exactly the same tree ring density data produce a hockeystick with a flat shaft and a hockystick with a wiggly shaft, then questions need to be asked about the methodologies before you apply them to other tree ring density data. Nobody likes people looking over their shoulder, but you have to let people _check your working_.

As opposed to chopping off the “decline” part and splicing on instrument data, for example.
Ok, with this it is clear that you are completely ignorant about the “decline” issue.
It was already justified, they already explained and were aware of the issues with tree-ring proxies showing declining temperatures in the later 20th century.

As you’ll see, very few commentators who jumped on the conspiracy bandwagon even before reading the e-mails managed to get it right.

Ok, with this it is clear that YOU are completely ignorant about the “decline” issue. See, I can patronise too!
The notorious “hide the decline” email is shown [here.](http://www.eastangliaemails.com/emails.php?eid=154) Note the subject line: “Diagram for WMO Statement”. The relevant WMO statement is here:
[Homepage | World Meteorological Organization WMO](http://www.wmo.ch/pages/prog/wcp/wcdmp/statemnt/wmo913.pdf). The diagram with Keith Briffa’s spliced data is the cover diagram, and it’s a nice scary bit of advertising. And I don’t have a problem with it - it’s cover art, and not meant to be a scientific publication.
Waht I do have a beef with is them doing the same thing in the IPCC Third Assessment Report. The report that went out to governments and policymakers. The report where they chose to show proxy data (Fig. 2.21) spliced with instrumental data, without disclosing anywhere that data had been spliced in that figure, or discussing the divergence problem anywhere. Pointing back to a Nature paper (which doesn’t itself splice the data!) and saying it was fine to leave that little factoid out of IPCC TAR3 is not good enough.

Of course this also shows that you did not look closely at the explanation. It was not a secret, researchers on that field already knew about the problems, as it was explained before, there was no need to mention that once again.

It was good enough for the National Academy of Science that investigated before and the University review/investigation that was made just last month. The issue was disclosed before and it was not a secret. It is a problem only by the denier media that omits lots of information already available. Instead of complaining about misunderstanding the science, it is high time to demand better from your sources.

> No doubt, instances of cherry-picked and poorly-worded “gotcha” phrases will be pulled out of context. One example is worth mentioning quickly. Phil Jones in discussing the presentation of temperature reconstructions stated that “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) and from 1961 for Keith’s to hide the decline.” The paper in question is the Mann, Bradley and Hughes (1998) Nature paper on the original multiproxy temperature reconstruction, and the ‘trick’ is just to plot the instrumental records along with reconstruction so that the context of the recent warming is clear. Scientists often use the term “trick” to refer to a “a good way to deal with a problem”, rather than something that is “secret”, and so there is nothing problematic in this at all. As for the ‘decline’, it is well known that Keith Briffa’s maximum latewood tree ring density proxy diverges from the temperature records after 1960 (this is more commonly known as the “divergence problem”–see e.g. the recent discussion in this paper) and has been discussed in the literature since Briffa et al in Nature in 1998 (Nature, 391, 678-682). Those authors have always recommend not using the post 1960 part of their reconstruction, and so while ‘hiding’ is probably a poor choice of words (since it is ‘hidden’ in plain sight), not using the data in the plot is completely appropriate, as is further research to understand why this happens.

(Skip to 4:00 minutes to get to the explanation)
As the tree ring data was shown to be unreliable after 1960 it was not then used. Published research already in the record mentioned before that it was not a good idea to use tree rings after the 60’s; then the other proxies from corals, ice cores and historical records took precedence. The data from thermometers was added and \*\*mentioned \*\*in the actual graph that appears in the Mann paper that was referenced by the IPCC.
It is only a secret when deniers do not show what the source said.

I should like to ask that such persons who feel compelled to assail the research a question: is the larger argument that if Jone’s research, data, methodology, modeling or web page should prove faulty, then that alone should place the entire intellectual edifice of AGW in grave peril?
Or is the struggle devoid of such sordid political taint, and simply the fervent desire that the scientific method be preserved in its pristine purity?
Either its the former, or somebody here is burning agenda incense. If so, it would appear to be based on a forlorn hope, that if only Jone’s can be nullified, all the other research will shrivel up and die. That would be like hoping to prove that Darwin deliberately fudged his research on Galapagos finches, which would mean that creationism is vindicated.

This also shows that you did not read what I wrote. I understand the explanation. I have no problem with the explanation. I think it’s an acceptable practise to splice proxy and instrumental data (IF you can justify your confidence in the older data once you’ve found divergence in the modern data.) The only problem I have is not mentioning this has been done in a scientific publication.
For the record, I will spell it out: I HAVE NO PROBLEM WITH THE “HIDE THE DECLINE” EMAIL. I THINK IT WAS AN INNOCENT REMARK.

Not from paleoclimatologists, no. But that’s not who the IPPC report was aimed at. I’m not sure which NAS investigation you’re referring to. Do you mean the NRC panel that Keith Briffa was actually invited to sit on, and then asked Mann for advice about? The one about which Mann said: “The panel is solid. Gerry North should do a good job in chairing this, and the other members are all solid. Chrisy is the token skeptic, but there are many others to keep him in check”? Because that’s not exactly what I call impartial. [http://junkscience.com/FOIA/mail/1139835663.txt](http://junkscience.com/FOIA/mail/1139835663.txt) Read backwards for chronological order.
I’m not sure that panel even looked at the issue of data splicing in the IPPC report anyway - the issue under discussion was Mann’s hockeystick.
your Deltoid cite is a rah-rah blog comment on another blog, deepclimate, and doesn’t itself say much at all. The deepclimate cite is actually pretty good, although it attributes to malice what could easily have been incompetence. To me, it is not so clear cut which parts of the data series the various comments refer to. The 1999 Briffa Science paper referenced by Deepclimate, where his truncated series is published, is not the Briffa paper referenced in TAR 3, where AFAIK his seried appears untruncated.

The panel of scientists was convened by the National Research Council (NRC) of the United States National Academy of Sciences (NAS)
And you do lose respect for going to Junk Science for evidence. As the cite from Deep Climate shows, they were correct on not trusting McIntyre.

And I would not be surprised that Briffa, that had reported early on the divergence issue, already took that into consideration. I seems that you are assuming here that the IPCC did not check the source, or that that they ignored what they saw in the source.

What is missing here is the fact that the emails are still referring to the reconstructions from 1999 - 2001, later Mann and Briffa came with even more evidence and this time McIntyre had to resort to accusations of cherry picking that he had to backpedal(?) from.

No. It may make the science more open and the record-keeping more rigorous, which is a good thing. It might put a stop to advocacy posing as science, and it’s certainly jolted the media out of their good-vs.-evil take on climate issues, for the moment anyway. The intellectual edifice of AGW is as sound as it ever was. Which is fairly sound, but not sound enough to declare that “the science is settled” or to label any and all skeptics as “deniers.”
I really do recommend Trenberth’s paper as a good summary of where the science is at, and the limits of our measurements and climate understanding.

If you had paid attention to previous discussions you would notice that deniers are not skeptics. BTW using a straw man is still not considered a good tactic.

The WSJ seems to think that the headline is some terribly important pronouncement that in some way undercuts the scientific consensus on climate change but they are simply using an old rhetorical ‘trick’.
>
> The phrase “the science is settled” is associated almost 100% with contrarian comments on climate and is usually a paraphrase of what ’some scientists’ are supposed to have said. The reality is that it depends very much on what you are talking about and I have never heard any scientist say this in any general context – at a recent meeting I was at, someone claimed that this had been said by the participants and he was roundly shouted down by the assembled experts.
>
> The reason why no scientist has said this is because they know full well that knowledge about science is not binary – science isn’t either settled or not settled. This is a false and misleading dichotomy. Instead, we know things with varying degrees of confidence – for instance, conservation of energy is pretty well accepted, as is the theory of gravity (despite continuing interest in what happens at very small scales or very high energies) , while the exact nature of dark matter is still unclear. The forced binary distinction implicit in the phrase is designed to misleadingly relegate anything about which there is still uncertainty to the category of completely unknown. i.e. that since we don’t know everything, we know nothing.
>
> In the climate field, there are a number of issues which are no longer subject to fundamental debate in the community. The existence of the greenhouse effect, the increase in CO2 (and other GHGs) over the last hundred years and its human cause, and the fact the planet warmed significantly over the 20th Century are not much in doubt. IPCC described these factors as ‘virtually certain’ or ‘unequivocal’. The attribution of the warming over the last 50 years to human activity is also pretty well established – that is ‘highly likely’ and the anticipation that further warming will continue as CO2 levels continue to rise is a well supported conclusion. To the extent that anyone has said that the scientific debate is over, this is what they are referring to. In answer to colloquial questions like “Is anthropogenic warming real?”, the answer is yes with high confidence.
>
> But no scientists would be scientists if they thought there was nothing left to find out. Think of the science as a large building, with foundations reaching back to the 19th Century and a whole edifice of knowledge built upon them. The community spends most of its time trying to add a brick here or a brick there and slowly adding to the construction. The idea that the ’science is settled’ is equivalent to stating that the building is complete and that nothing further can be added. Obviously that is false – new bricks (and windows and decoration and interior designs) are being added and argued about all the time. However, while the science may not be settled, we can still tell what kind of building we have and what the overall picture looks like. Arguments over whether a single brick should be blue or yellow don’t change the building from a skyscraper to a mud hut.

This was also explained and remarked in the video posted before, Tremberg knows that global warming is unequivocally happening. The problem has been calculating properly where the heat is going to, so then we can be better prepared for the changes that will take place.
Of course other researchers are reporting where the heat is going and that is why those that say that global warming stopped in 1995 or 1998 are not correct.

Good grief. Do you ever ENGAGE WITH THE MATERIAL PRESENTED TO YOU instead of attacking the source? The ONLY information in my link are hacked/leaked email exchanges between Mann and Briffa. I Googled Mann, Briffa, NAS and North and the junkscience link was the first hit that showed what I was looking for. I invite you to look at it, albeit on the oh-so-terrible junkscience site, and actually read the 3 or 4 emails between Briffa and Mann. Then comment on how impartial the NAS panel was, if you care to. “Lose respect” indeed.

Again, as far as know the IPCC source does not show truncated data, although I’m willing to be corrected on that. I have no access to Briffa’s 1998 paper. I think the IPCC authors of that figure took data from the source, truncated the diverging data and didn’t mention the truncation.

??? Your own Deepclimate cite shows that McIntyre was talking about the 1999-2001 period. McIntyre may have associated the wrong comments with the wrong parts of the graphs, possibly deliberately, but I don’t understand the point you’re making here.

As McIntyre said:
“I’m assuming that CA readers are aware that, once the Yamal series got on the street in 2000, it got used like crack cocaine by paleoclimatologists.”
The problem with deniers like McIntyre has been that they assume the same tactic will work today just as it was used “successfully” before. The point here is that just as he was wrong regarding the early reconstructions, he was wrong also when criticizing the latest one.

Ooh, did I miss a meeting? AFAIK, what you call “deniers” ARE skeptics, but skeptics aren’t necesarily deniers. And the strawman comment is pretty rich considering you appear to be debating someone in your own head rather than me.
I’m not a denier at all, and I’m a fairly mild skeptic. I think too much confidence is expressed in our understanding of climate change, and that’s it. I recommend Trenberth’s paper because it’s a good summary, not because it supports a skeptical position (it most certainly does not).

Now I understand. You want to argue with Steve McIntyre, but I don’t believe he posts here.

I will let others figure out if claiming that scientists are saying that “the science is settled” was not a straw man argument.

And it is a summary that I also agree with, adapting to the **climate change** is an imperative if nothing is done to control global warming gases.

Good, the less he is referred to the better. It just so happens that early you mention that McIntyre was not fairly treated when he was trying to get information. What it is clear is that McIntyre can not be trusted with that information as he is really not telling the whole story:

The videos already are a good comment on the emails, cherry picked and missing a lot of the context, useless to make any judgments in almost all the cases mentioned in the CRU hack, except for the usefulness of allowing deniers to mislead others.

So \*\*who \*\*is saying that “the science is settled” then? As I did not said that, I had to assume it was your take on what scientists had said. And if you still want to weasel out of that one, who is labeling all skeptics as “deniers”?
It was a straw man argument.

IIRC, previous FOI requests had been turned down on the grounds of confidentiality agreements, so that FOI does in fact make sense and is not necessary “vexatious”. And I DO think Jones would have been much better off giving out his data, or better yet, putting the non-confidential data into a public database as I believe Judith Curry has suggested.

The media, politicians, bloggers, probably some SDMB posters… one member whose name I won’t mention has stated explicitly on these boards that AGW deniers are equivalent to holocaust deniers. But anyway, a strawman argument implies an attack. Where in my reply to **elucidator** am I attacking anyone? I made a statement of my belief - "the intellectual edifice of AGW is as sound as it ever was. Which is fairly sound, but not sound enough to declare that “the science is settled”. Where’s the strawman?
