    Let's talk about the current paper: what do you think of the way Mann calculated error bars and uncertainty?

    LOL, you mean you are not going to let me get away with being "sceptical of any only recently published paper" while the actual experts in the field boot it around for a year or so; you want me to read beyond the abstract?! I really ought not allow you to draw me here ...

    To be frank I lack the expertise to form any reasonable opinion (which is why I defer to the orthodox position). My own science degree (and it was a mere BSc) was in Pharmacology & Psych, where papers were altogether an easier beast methodologically to pull apart. Moreover, there's a lot of water under the bridge and my NY resolution finally to learn 'R' and revivify my stats is yet to come to fruition ...

    Sooooo you'll forgive me if I'm very slow on the uptake here ... but unless you are pointing to the fact that there are no error bars on the graphs per se, the uncertainly expressed (in Table 1) is +/- 1 SD. That would be a fairly common measure of uncertainty. You find that inadequate to the task?

    Why? Mainly because it most clearly demonstrates the issue.

    It's not clear to me, especially in light of the faux pas about CRU, just what issue that is. My intervention, as you will see if you refer to my original post, as well as pointing out that you had the wrong Man(n) (you had Jones) and taking issue with the hyperbolic attack on the statistical failings, such as they were, of the good Professor: was that the original hockey stick paper has long been superseded.

    In any case, it is my (limited) understanding of Mann, Bradley & Hughes 1998, is that it is generally accepted both that better statistical methodology could have been applied; and that the methodology actually used contained identifiable mistakes (however minor they may have been). I believe Dr Mann himself concedes as much. "Really really bad," however, probably tends towards hyperbole.

    If he knew what he was doing, then he was actively trying to deceive people, which is far worse.

    That's a reading the "hide the decline" [of correlation between tree-ring and other proxy data relating to the sub-set of Russian trees after mid C20th, was that it?] comment might naturally lead someone to form. But really isn't it just the that the blow-tourch of criticism on this particular subject matter renders good-enough methodology not nearly good enough? Scepticism, where it is informed, is a great boon to science.

    Tell me about it!

    The only saving grace you can grant Mann here ...

    Are you still talking about that 20 year old paper or the present one? And if the 1998 paper, then why? Have I defended that paper in this thread? Beyond foregrounding the fact that the work which has superseded it has "more or less" confirmed the original findings? I merely noted that calling Dr Mann "really really bad at statistics" was "perhaps" to overstate matters. (No really, look back at what I've written).

    (Off topic, I did hint at the fact that I don't accept the view science can simply ignore data sources which are subject to difficulties of interpretation, which seems a form of the nirvana fallacy). But it being not strictly germane, and this being an old discussion, I'll decline any invitation to go down that line of argument here. Which nicely segues ...

    The only time, I trust, that I am ever willfully ignorant, is in my refusal to "hear" statements clearly irrelevant to the point under discussion ... a perverse outcome of my legal training, you will understand.

    In other words, they weren't able to establish that their measurements were proxies for temperatures.

    Don't be disingenuous. They were not able to make, as you quoted, any "statistically robust" reading based on the both the parcity of data and the fact that the C20th is too shorter a period to make any meaningful statement under their methodology. You know this because, once again, it lies adjacent to the cherry-picked verbiage you misquoted:

    Our global paleotemperature reconstruction includes a so-called “uptick” in temperatures during the 20th-century. However, in the paper we make the point that this particular feature is of shorter duration than the inherent smoothing in our statistical averaging procedure, and that it is based on only a few available paleo-reconstructions of the type we used.

    I've been modded down already

    Well it wasn't one of your more accurate contributions was it? Oooops.

    Beside the confusion between Penn State and the University of East Anglia, to say Dr Mann is "really really bad at statistics" is perhaps to overstate the actual criticism leveled at his now infamous 1998 paper. In any case subsequent reconstructions, --and the last word, I presume, goes to Marcott et al. 2013 --more or less confirm the original conclusions of Mann et al.. I'm would assume you (and I genuinely respect your intelligence and erudition phantom) are already aware of that.

    it's also worth mentioning that this paper is using computer models

    And, invaluable though they may be, we would certainly exercise caution when considering the findings of simulations. In any case, we would naturally be sceptical of any only recently published paper. It's the weight of the extant literature of course, including the examination and perhaps replication by the entire profession of newly published work, that forms the best available science.

The human contribution (established not only by the C12/C13 ratios but also by estimates of rates of fossil fuel consumption) is no longer a matter of serious dispute. The argument has moved on to issues of climate sensitivity; just what the actual effect will be on tropical storm formation &c. If you want to see the original work establishing the human fingerprint you would need to look at papers from last century, when this was still a live issue. You are better off going to the most recent IPCC summation of the science (which will link you through to original papers), which in this case would be Chapter 8 and Chapter 10 of the 2015 WG1 report of AR5.

    So what do you propose instead? Keep in mind that blaming the accused (before evidence or judgement is given) is basically as wrong as blaming the accuser. How do you express skepticism or withhold judgement in a way you see as correct?

    As you say it's "basically as wrong" to go one way or the other. I already answered this above, but to recap: What I propose is nothing more radical than adhering to the ordinary presumptions a court is required to make, for example, in a criminal process. That is to say that a) the accused is entitled to the (rebuttable) presumption of innocence and b) the accuser(s) (and indeed all witnesses) are entitled to the (rebuttable) presumption of honest testimony. As I wrote above, the process can be thought of as a resolution of the contradiction thus set up.

    If there is relevant evidence tending to speak to a client's guilt, one seeks to exclude it on the basis that it is unlawfully obtained; hearsay; tendency or coincidence evidence; &c. Bearing in mind the restrictions due to the credibility rule, one seeks to impugn the reliability or character of the witness; to show the testimony is self-serving; &c. And of course, where possible, to show that the evidence led is demonstrably false. However, the mere fact that evidence that tends to show the guilt of an accused is not a reason to presume that evidence is false (and then have to prove, beyond reasonable doubt, its veracity). The point of the presumption of innocence, after all, is that the state lead evidence to rebut it.

    Now as private citizens reaching mere opinions, we need not, of course, be anywhere near as punctilious as a court, much less need we work to a criminal standard of proof (my opinions are held on the 'balance of probabilities'). However bearing in mind the proper presumptions as we consider the limited evidence available should stop us jumping to hasty conclusions either than an accused is guilty or an accuser a liar.

    What's the right thing to say when one of your friends states that either the accuser or the accused has done Horrible Things?

    How about: "You know I really envy your confidence in coming to quick conclusions with very little direct evidence." ;) Being the contrary bastard that I am, I often begin arguing the opposite of any position put to me. TBH, I'm a bit self-centred, probably you'd get on better with people if you just go along with the tribal prejudices of your friends.

    If you lead with sympathy, you're good. If you lead with accusations, then you're bad.

    A problem, I think, is that too many people assume the presumption of innocence we must extend to an accused, involves a corollary presumption of guilt against the veracity of the accuser. That is not so. Someone making a complaint is entitled to the rebuttable presumption that their accusation is made in good faith, just as the person against whom the complaint is raised is entitled to a presumption of innocence.

    The "process" --and this clearly applies to a curial process, but arguably it ought also apply to an investigative one --might be understood as a process of resolving the contradiction, by reference to the available evidence, between the two presumptions reason (or law) requires us to make.
