Thanks for all your one liners Shot. Although I assume you're just being snarky, I'll try to answer them.

What is immediately interesting about this paper (and what was interesting to me) is that it is independent confirmation/replication of the conclusions that Steve McIntyre came to when auditing Mann, that the proxies used were found to be unreliable indicators of past temperature, confirmed by the authors result that random (red) noise actually gives a better model fit than when using the actual proxies. Really, this is a replication of an already established result, though ignored by climate scientists.

Since all the data and code are provided, there's no issue that this paper can't be replicated. This is already behaviour worlds away from the long drawn out fights over basic data and methods that has extensively been covered in Climategate and elsewhere. As I said, anybody with the chops to do so can do this work. It's certainly not going to be done by me. But cheers for pointing that out again.


PS, the intention of the authors is not in offering up their own version of the hockeystick- which is a point being missed on various pro-climate blogs. They are saying that the proxies are useless for the purpose assigned to them, that of determining historical temperatures with any degree of certainty or skill. The proxies fail.




Quote :My eyes blurred over at the statistics but these guys are professionals in their field

Climatology relies on statistics. (edit: and perhaps in this case, not being climatologists should really work to the benefit of the authors as they would likely be immune to any potential biases and preconceived notions about results).


Quote :What's great about this paper is that all methods and data are laid out for anybody to check.

See above. Also, I did have a go at reading the paper. Did you? Just how many papers have you been able to replicate before you accepted the findings of the authors? Do you not accept anything that you haven't put in the work to replicate personally? Let's see where you show Mann is right and these new authors wrong. Do you not 'like' the new paper? Why?

Apparently there's this maxim in science which goes something like 'trust, but verify'. Which sounds sensible. What I don't accept (and you can see that this has been my basic argument in this whole thread) is this new idea of 'trust, I'm a scientist', and then withholding the means by which to verify. As far as I can tell, anyone can get on board that, you don't need to be a scientist to see there's something wrong with that. Verification is a straight forward process. If you can't verify, then it makes it that much harder to trust.

Explained above. (the author's honesty is relatable to them immediately putting up all material and methods for easy public access). The paper itself may be heavily contested in both climate and statistics journals.

Quote :

From the recent Oxburgh enquiry.
Quote :
“The panel found that the statistical tools that CRU scientists employed were not always the most cutting-edge, or most appropriate. “We cannot help remarking that it is very surprising that research in an area that depends so heavily on statistical methods has not been carried out in close collaboration with professional statisticians. Indeed there would be mutual
benefit if there were closer collaboration and interaction between CRU and a
much wider scientific group outside the relatively small international circle of
temperature specialists.

and

Quote :“The Report points out where things might have been done better. One is to engage more with professional statisticians in the analysis of data. Another, related, point is that more efficacious statistical techniques might have been employed in some instances...

...we do see the sense in engaging more fully with the wider statistics community to ensure that the most effective and up-to-date statistical techniques are adopted and will now consider further how best to achieve this.”

The Wegman report, 2006
Quote :
Conclusion 3. As statisticians, we were struck by the isolation of communities such as
the paleoclimate community that rely heavily on statistical methods, yet do not seem to
be interacting with the mainstream statistical community. The public policy implications
of this debate are financially staggering and yet apparently no independent statistical
expertise was sought or used.

Plus the fact that, they don't.

Who cares what I say. The point is that CRU and others have a history of not providing their data to anyone, scientists included. Unless you're friends with the guy who wrote the paper. Then that's o.k.

Quote from Shotglass :nice way to brush away reality

You lack the proper context for this paper and where it fits into the overall history of the hockeystick controversy and the literature. I forgive you for imagining that this is something which has just come out of left field, but I can assure you that's not the case. Various conclusions and concerns of this paper have already been articulated through previous papers, expert panels and congressional hearings. For the lazy, here's a wiki entry for the history of the hockeystick so far. Of course, this can only begin to scratch the surface.

All I'm conveying to you are the conclusions that I've been able to draw from my reading on the robustness of these constructions. They do not look good. This is pretty much confirmed even by the original authors themselves. They admit a great deal of uncertainty and have recently quietly admitted that sans a number of contentious proxies (bristlecone pines and the contaminated Tiljander series) the reconstructions show no statistical skill prior to 1500. Statisticians have consistently been at pains to point out that the proxies are pretty much useless as indicators of past temperature, and this new paper is further verification of that. I'm just telling you what they told me

So at first we had a worldwide scientific consensus. Now we have a topic still under discussion.

I say we're making some sort of progress. I hope the policymakers have not taken sides yet and will 'wait things out' as it is the smart thing to do from dumb people.

I'm extremely happy to wait things out. Where was I 'flapping my mouth off?' or where did I say this paper was correct beyond reproach? All I offered was that this papers conclusions are consistent with previous papers in the lit, and then I pointed out that you seemed to be unaware of this. You can check that my 'enthusiasm' for this paper lies in the fact that the authors haven't hidden anything away to be second guessed by anyone else. All data and methods are available, and I contrasted this with the prior behaviour of Mann, which I find deplorable in this regard. This 'discussion' as you put it has been ongoing since 1998, in the literature and outside of the literature, and I've tried to follow it all the way along and I've listened to both sides with extreme interest. I am educated on the issue, even if the finer mathematical points elude me. But there is nothing at all 'shocking' about this paper for me to assume that it is a wrong footed approach. Again I point out that these things have been said time and time and time again. I will wait for an official rebuttal from the original authors along with everyone else. That's what you do.

The problem with this approach is that as has been demonstrated in the past (e.g. hockeystick graph) some of the people who are supposedly experts in the field are not being objective in their methods or analyses. When you have people being given research grants and funding from governments (e.g. the CRU) the chances of getting data back that's objective are in question. I'm not saying that "citizen scientists" have the expert knowledge in the field (or even the authority to attempt to invalidate what has already been published). What I'm saying is that one of the foundations of scientific research (namely objectivity) is compromised when governments are funding research when they already have extensive work under-way that relies on a particular outcome from that research.

I would disagree with this. I see the problem as being one where a branch of experts, in this case the statisticans, are not being given their proper dues- and then people are not being objective about their arguments or are made simply unaware of or are willfully unaware of the arguments, for whatever reasons. On blogs and in the media you hear an awful lot of people defending climate scientists from the point of 'when I need my car fixed I don't call a climate scientist. I call the mechanic. But when I need to know about the science of climate change, I listen to and trust the climatologists'. Similarly, in this new paper, the statisticians have made no judgment on the quality of the data being used...

Quote :“We assume that the data selection, collection, and processing performed by climate scientists meets the standards of their discipline. Without taking a position on these data quality issues, we thus take the dataset as given.”

What the statisticians have done is simply attend to the area of their expertise. If you can't accept statements made by the statisticians on the quality of statistics being performed by non statisticians, that their arguments are invalid because they are not climate scientists, but then you are also making arguments on the authority of climate scientists, then you are not being symmetrical in your argument.

This 'citizen scientists' term is misleading here. Both the Wegman panel and the North panel were in sum representative of the top experts in the fields of both paleoclimatology and statistics. They both came to similar conclusions.

Quote :
The Wegman panel was made up of three statisticians from three different universities, none of whom had any professional connection to paleoclimatology or the AGW debate. The North panel was made up of eleven paleoclimatologists and two statisticians, most of whom had been professionally connected to the IPCC or the Hockey Team, some of them closely connected. So this jury was well and truly stacked in Mann’s favour. He acknowledged this to Keith Briffa in an e-mail urging him to appear before it as a witness:


I think you really should do this if you possibly can. The panel is entirely legit[im]ate, and the report was requested by Sherwood Boehlert, who as you probably know has been very supportive of us in the whole Barton affair … The panel is solid. Gerry North should do a good job in chairing this, and the other members are all solid. Christy is the token skeptic, but there are many others to keep him in check.


But despite its AGW bias, when the North panel presented its report in June 2006 it acknowledged that the Hockey Stick’s depiction of temperatures before 1600 was invalid. It reported that the Hockey Stick depended on bristlecone pine proxies that “should be avoided for temperature reconstructions”. That its reliance on single validation statistics was unacceptable. That its short-centring methodology was biased, towards a hockey stick shape. That it used methodology that was “unconventional” and “problematical” such that it “introduced certain distortions”—that is, was wrong. And more. It concluded that: “Some of these criticisms are more relevant than others, but taken together, they are an important aspect of a more general finding of this committee, which is that uncertainties of the published reconstructions have been underestimated.” This was a highly euphemistic summary of the report’s specific findings. The panel made no criticism of McIntyre or McKitrick or of the papers they presented.

Quote :The Wegman report identified a hard core of seven authors and a “social network” of forty-three authors with direct ties to Mann, and reported that this network had compromised independent research, perverted the peer review process, and so tied researchers to their public positions that they had become incapable of reassessing them. It criticised the team’s isolation from mainstream statisticians in other disciplines, and its grudging and haphazard release of the data required for verification of its findings. Most importantly it found that “the decentered methodology” used to produce the Hockey Stick “is simply incorrect mathematics”, that the Hockey Stick has “a validation skill not significantly different from zero”, and that its obliteration of the Medieval Warm Period and contention that the 1990s was the hottest decade in a millennium were “essentially unverifiable”.
The team attacked the Wegman report on the grounds that it was not peer reviewed, which was ridiculous since it was a peer review—a proper independent one by three of the most distinguished statisticians in the country.

Let's be real here. Critics of Mann are not simple backyard statisticians with delusions of grandeur. They are respected in their field. They have shown to be correct, even by scientists in close personal connection to Mann. Where Mann's supporters generally tend to differ is in their take on whether the criticisms matter... not that they are somehow wrong.
Quote from Electrik Kar :I would disagree with this.

What would you say about practices such as selecting data specifically to fit an ideology (as occurred with the Yamal sampling)? If the raw data you pass on is intentionally filtered to fit a particular ideology then no amount of good, honest work in the future can account for this. Fruit of the poisonous tree.
To put an end to the discussion so to speak, forget what you hear on the news, other people, etc, when you walk outside, do you notice a bloody difference in the climate?

Because climate (whether it's goin tits up or not) affects everyone, everyone can judge for themselves, by going outside, taking their own tempreature readings over a period of time, and they will see that, all the CRU and other organizations do, is manufacture government fueled shite.

To anyone who believes in climate change : do you not think it's strange how this benefit's any government that uses it?

As many dictators have said and will continue to say, fear is the most powerful emotion, if you strike fear into your populous you can get them to do what you want, instead of using religion to control the citizens they are using science, which is effectively a religion as it's manufactured to create the maximum effect.

It's been happening since the beginning of time, the governers would say if you do this, this, this or this, the gods will smite you. Effectively it's the same thing happening now, they are basically saying the world is ending to get you to pay more tax.


Edit : Take F1 for an example (something we can all relate to on here), some of the circuits they have been going to for decades, and have they ever said that the track tempreatures were abnormally high or low? No, they haven't. It's the same each year they go to these places unless there's a weather difference of course.

What you call cherry picking Keith Briffa would probably call a problem arising from a limited sampling of cores. Steve M has recently posted on the issue of the existence of another set of data (an updated Polar Urals chronology) which has been available since 2000. These are valid measurements according to Briffa and should really be used to gain a more reliable result in his reconstruction. So far, Briffa has not done any re-analysis taking into account these other measurements.

http://climateaudit.org/2010/0 ... ndertaken-any-reanalysis/

Remember, this data has been available since 2000. But according to Briffa (in answer to Muir Russel), there has been no time in which to do the work, and alternatively (to Steve Mc) that he hadn't even considered it. This is all very strange. I'd recommend reading through the post linked above. If you come away from it with the feeling that Briffa isn't interested in updating his data, which might then give differing results to those included in IPCC, ie- it's basically a case of cherry picking and ignoring evidence- then I wouldn't hold it against you. I also get the same feeling.

3 out of 4 data sets disagree about the announcement that "So far, this has been the hottest year in recorded history."

I'd suggest an actual check of the data before believing what the papers tell you. But I understand you're a smart guy, you already know that. I agree completely that this is a hot year globally. No complaints there.

Quote from PhilS13 :So at first we had a worldwide scientific consensus. Now we have a topic still under discussion.

the worldwide consensus that the climate is warming still stands and so does the consensus that co2 is a greenhouse gas
how large the spike in warming compared to the past and how much of an effect co2 has are is still subject to ongoing research

Quote :Where did I say that it was?

while you may not have said it as such you certainly did imply that it had any sort of relevance in the ongoing scientific discourse

Quote from amp88 :When you have people being given research grants and funding from governments (e.g. the CRU) the chances of getting data back that's objective are in question.

this may just be a case of you never having seen a university from the inside but research is usually largely state funded
particularly in fields like eg particle physics (lhc) or paleontology where unlike with eg engineering research there is very little chance of getting marketable results and thus no interest from short term oriented businesses in any way that would case them to throw money at the scientists
and even in fields like engineering industry money is an issue as it stops any research into the fundamentals dead in favour of improving already existing technology which amounts to merely scratching the surface of the science
Quote :

Of course I don't ascribe the behaviour of one or a few men to be representative of the behaviour of the entire field. But on the other hand we were not talking about these other men/women- I don't think we have the entire thread, which is probably a great shame. In fairness, the point should be made that the people we have been talking about do enjoy great power and influence within the climate community- they are lead authors of IPCC, head of CRU, etc. My opinion on that is that it is regrettable. As leaders in their field they should acknowledge some kind of responsibility in being better role models for openness and transparency and fairer play with critics. My problem with climatologists is really a problem with these few people, and you are certainly right to point out that not everybody is like this.





Quote :while you may not have said it as such you certainly did imply that it had any sort of relevance in the ongoing scientific discourse

I believe it's relevant. It was made up of scientists who were critiquing and giving recommendations on the current state of science at the time. In my definition that is a scientific discourse (if it wasn't relevant I don't think they would have bothered).
Been out of action for a week or so. I had no idea this thread had re-ignited.

Quote from Shotglass :ok so let me get this straight
the idea of being a citizen scientist is to read papers (i rather doubt you actually read through the 45 pages (especially in one night... i read papers regularly and its completely impossible to understand more than maybe 10 pages of a properly written paper in one night)... i sure havent got the time to read all of that)

Yes, I read the paper in one night. It was pretty easy to do, which you'd see if you read it, and already being familiar with many of the papers cited made fairly light work of it. I get time on an evening to do things like this.
Quote from Shotglass :you dont understand and are completely unable to reproduce the math of yourself due to that lack of understanding and knowledge and then to overstate the importance of that one paper because it fits your view?
is that about correct?

No, not really. I understand a great deal about the science behind proxy reconstruction, I know the basics of principle component analysis. I understand the use and purpose of red noise to test a methodology, I understand holdout blocks and most of the other tests that are applied to the proxy reconstruction data. I'm not a statistician, doesn't mean I'm stupid.
Quote from wsinda :Does that mean that the writing style is good, or that the scientific results are correct?

It means the writing style is good, and it means that many of the results of this paper address issues that I'm already familiar with as being previously identified deficiencies in the work of Mann 98-08.
Quote from wsinda :I guess it's the former, since you continue with
..., which would mean you're not able to verify the correctness. AGW is all about statistics. I have an MSc in math, but in a different specialisation. I'm pretty damn sure I can't tell correct results from shoddy work in this area.

If, by AGW, you mean paleo reconstruction, then I would agree with you that most of the work is based on statistical analysis. And this is actually why the MW10 paper is so significant, because this is the first time that an in-depth analysis of the proxy data has been performed by professional statisticians. If you didn't know already, paleo scientists like Mann, Ammann etc. are not statisticians, and don't pretend to be.
Quote from Shotglass :have you ever actually read a paper? if its the usual type you need a degree and at least a couple of months worth of work on the specific subject the paper is about just to understand half of the abstract

Worthless argument from authority.
