In response to the high-variability recosntruction of Esper et al. [2002] posted up here , Mann and Hughes [Science 296, 848 (2002)] replied: The basis used by Esper et al. for comparison with previous studies of NH temperature trends over the past millennium is flawed [imagine Mann calling someone else’s work "flawed"] … Some of […]
In August 2005, the new editor-in-chief of GRL, Jay Famiglietti of UC, Irvine, took over control of our file after two comments, including one by Ammann (UCAR) and Wahl had been rejected by the previous editor. This is discussed here . He gave an interview to Environmental Science & Technology here in which he was […]
Update: a new heavily-edited version sent to me this a.m. by Ross, edited somewhat through the day here. Ross to the rescue. Here’s a draft Powerpoint presentation for AGU. As with most first drafts, it’s pretty uneven. The topic of the session is variability, so I’ve spent the first part of the presentation on that. […]
As a mindless activity, I’ve re-visited the Crowley data, which we’re discussing. Among other stereotypes, out of 15 series, Crowley uses 2 bristlecones, Polar Urals, Tornetrask and Dunde. Even so, without any grafting, there’s not much hockey-stick-ness to this dataset. When you parse Crowley, you also see some very odd decisions, which result in lowering […]
I’ve been re-visiting the various multiproxy studies with respect to scale and variability. In addition, as you know, one of my interests in these multiproxy studies is the non-robustness of MWP-modern levels to a very few non-independent proxies, used in multiple studies – in particular: bristlecones, Polar Urals and Thompson’s Himalayan dO18 series – each […]
If any of you have young children and heavy unsecured television sets or the like, proceed immediately to ensure that they are completely secured or remove them. American Thanksgiving weekend has been very black here. On Sunday evening, our 2 year old grandson, a bright, handsome and active child with a mass of curly blond […]
Some of you may have noticed how surprisingly high climateaudit ranks in google searches in topics not obviously connected to us. I did a google on "full true plain disclosure press release" and, lo and behold, there was CA at the top of the list. Here are few other rankings.
Spence has drawn attention to Hans von Storch’s comment at Roger Peilke’s, giving his take on the hockey stick debate here: The debate about the hockeystick is techically not really relevant. We have achived our main goal, namely that the premature claims that the issue of millennial temperature reconstructions was mostly solved have been broadly […]
I never quite got to presenting an attempt to replicate Moberg before. Here’s a try. I’m still a long way off from being able to replicate his results. It is so infuriating to have to try to do such an amount of detective work prior to even atempting any analysis. I presume that has been […]
Yesterday I waded through a demonstration of a fairly egregious splice of the instrumental record into Crowley’s reconstruction as used in Crowley [2000]. Today I consider the use of the Crowley reconstruction in spaghetti graphs and, in particular, Mann’s statement at realclimate that: No researchers in this field have ever, to our knowledge, "grafted the […]
