CNN Tomorrow

John Roberts’ show at 6:20 am to talk about the Parliamentary Committee. Roberts visited CRU in the heat of Climategate. They said that I would be appearing with Michael Mann – anyone heard of him? In the re-confirm, they said that I’d be appearing with Mike MacCracken.

    One day, it will happen.

    Like Mann wants to go Head-to-Head. My guess is that they probably didn’t tell him you would be on till you confirmed, at which time he cancelled!!

    Ask MacCracken about Professor Hansen’s thermometer.

    I agree with Oliver Manuel. 🙂 The very idea of Michael Mann agreeing to appear on the same show with you is entirely suitable for an April Fools joke.

    Next thing you know, Phil Jones will have jocular fun on Good Morning America with Warwick Hughes, and Gavin Schmidt will be featured on Dancing with the Stars sashaying around with Sallie Baliunas.

    On day 2, pigs will fly.

    You sure that’s not Phil McCracken?

    I agree with KuhnKat about the likely order of play. The courage of the main protagonists in this shambles never fails to inspire. Don’t mention the war – or even the name of the person who has single-handedly taken you down, in everything but name (and juicy government grants). What heroes we’ve created for the next generation of scientists to look up and aspire to. What a shower.

    Never happen, Steve.

    To quote William F. Buckley, Jr on why Robert Kennedy refused to appear on “Firing Line”. . . . . . . . “Why does the bologna reject the grinder?”

    I am having great difficuty in posting new information on
    your web
    My research to date shows that the 1 sigma data error in the monthy data set
    from Hadcrtut3 and the UAH are
    0.098 degree
    0.086 degree

    If this is true then the error bars placed on yearly graphs,taking Hadcrut3, should be

    0.098/sqrt 12 = 0.0263 degrees.

    I must be wrong

      Quantifying uncertainty in cases like this can be difficult for many reasons: The “sampled” population is not the same as the “target” population (potentially introducing bias and, where adjustments are made, errors associated with the adjustments); observations are correlated in time and space (reducing effective sample size); there may be substantial systematic bias in the data; etc. As a result, one should be cautious about assuming that mean square error is inversely proportional to sample size.

        Yes I am very aware that there are considerable computational steps between the mercury, and microwave readings, and the published monthly data.Because the data deals with differences from a set time I am assuming that these algorithms ,instrument corrections etc do not change otherwise tracking global temperature changes will be extremely difficult and any conclusions could easily be refuted.
        What is interesting is that the Hadcrut3 and UAH monthly variance are very close.I assume that the two datasets are independant and this encourages me to press on with my analysis.

    General, off-topic question:

    What is the current state of play regarding data and code requests that have not been satisfied?
    Has there been any improvement?

      Re: Punksta (Apr 2 05:59),

      A good question. And what’s the status of the RC data links/site/whatever it is? Someone linked to it yesterday I think. I believe when it first came out someone, maybe even Steve, mentioned that there was still lots missing, though it was an improvement. Has anyone actually searched through it to see if needed stuff is hiding in there?

    This is a link to the CNN interview. I hope I get it right. If not, the video can be found on the video tab, “Tech” category, titled “Mixed messages from climate review panel”

      Re: per (Apr 2 09:35),

      At least that version isn’t very helpful. And the McCracken character made an incorrect statement (I believe)when he claimed that NASA and NOAA went to the original sources for data, as had CRU. In any case, the important thing is knowing exactly what data was used and it’s been like pulling teeth to get that information.

      You have to applaud CNN for hosting some kind of a discussion about the UK
      committe, even if the feed was too short and I would have liked Steve to get
      a chance to rebut Mr. McCracken’s last comments.

    With all the Steve McIntyre fans around the world this event should substantially boost CNN’s sagging ratings.

    I see a pattern here. A while back, Roger Pielke Jr. was to appear on NPR along with Mann and a couple of others sympathetic to Mann. But Pielke explained, within hours of the program, “NPR called back to let me know they won’t be able to have me on.” Is there any doubt that Mann refuses to face anyone who is willing and able to challenge him?

    Mann also wrote an op-ed for the Washington Post back in December to defend himself. He could have tried to refute statements from McIntyre or other experts, but instead, he took on Sarah Palin. He’s clearly afraid of anyone armed with the facts.

    Well done. It was a pity that Roberts gave McCracken the last word which he used to misrepresent the situation on how the data sets are actually constructed.

    Too bad Steve wasn’t able to speak directly to the “hide the decline” issue. I may be projecting, but I got the impression that Roberts was steering him away from that.

    Well done – Steve got his points across well.

    Strange that an able and committed scientist such as Mann should shy away from open discussion.

    Thank you Steve, well-said as ever.

    I do wish, though, that Roberts had asked for you to respond to McCracken’s statement about ‘hide the decline’. Roberts said (my rough transcript) :

    “Datasets have to examined very carefuly. They are valid over certain date ranges and certain conditions.
    What was found with the tree-rings .. they were valuable over a certain period, they were set-up to look at a particular period. They didn’t seem to work in more recent decades. That needs to be looked at, there’s no question about that. But that’s true of all data-sets, and the adjustments that have to be made to figure out what they’re really telling us.”

    We still know little of what these ‘certain conditions’ are, and we don’t know if these unknown conditions applied for the period under consideration. The divergence problem, while acknowledged, is unresolved – at least it lets us know that sometimes the growth of tree-rings doesn’t reflect the temperature.

    Steve, you are truly a hero to many that believe in apolitical science. You have said on several occasions that you believe in global warming and that your only interest is getting the data correct. Given all the problems with the hockey stick, integrity of temp. data sets, UHI, etc., what exactly is the basis for your belief?

    As for “Climategate”, Jones has been fully exonerated, so I don’t know whey everybody isn’t just moving on.

    Steve, you seemed a little off your game on CNN, and appeared to lack conviction. I get the feeling that this isn’t your favorite topic.

    steve: there’s a difference between official institutions deciding not to do anything and institutions carefully investigating and exonerating someone. The Committee did not receive any evidence that discarding tree ring data, for example, was a valid statistical procedure – the Jones resolution was simply a vote of three MPs against one.

      So if someone is wrongly exonerated, one should just “move on” and forget about justice?

    Nicely focused talking points. To bad McCracken was able to get that cheap shot about all the data being out there at the end.

    I really have to wonder about Steve’s answer regarding the filing of the FOI requests, “I haven’t personally, I haven’t filed many, many FOI requests – I filed some…”

    Isn’t it a bit disingenuous to ignore Steve’s coordination of the FOI request filing from last July?
    [snip – unfounded allegation]

    Good job Steve, while these types of things are hardly ever as in depth as we would like, I took away from it McCracken admitting the data diverged and should be looked into. I also noticed he did not say it had been.

    Slightly different subject:
    One of the emails I had read spoke about smoothing out the “bump” in Ocean temps to get the desired results. I wish this email could get more light shone on it as it is long and can not be construed as being taken out of context. The author explained exactly why he was doing it and went to explain he did not want to remove it entirely then someone might notice the miscorrelation between ocean and land temps.
