Weaver Suggests Buddy Review for Mann et al 2005

Coauthors of Rutherford et al (J Climate 2005) (pdf) were Rutherford, Mann, Bradley, Hughes, Jones, Osborn and Briffa.  Its editor was Andrew Weaver.  It was formally submitted on Sept 16, 2003,  received two reviews in January 2004, revised and resubmitted on June 29, 2004, accepted without revision on September 27, 2004 and published in July […]

Weaver on Tortious Sarcasm towards an Academic

In 2005, serial litigant Andrew Weaver, now a politician but then an academic at University of Victoria active in public controversy, threatened Climate Audit about alleged defamatory remarks.  I asked Weaver to explain why the seemingly innocuous remarks (by John A, not myself) were supposedly defamatory. As I understand Weaver’s theory of libel, sarcasm towards an […]

More on the Gridded MXD Data

We’ve noted that Briffa’s gridded MXD has high correlations to temperature, much higher than run-of-mill proxies. We’ve also noted that Mann (like Briffa) truncated this data at 1960 because of divergence. At the time that Mann et al 2008, the gridded MXD data was not available anywhere – Mann cited a webpage as follows: The […]

Mann 2008: the Briffa MXD Network

Those who forget the past are condemned to repeat it. The SI for MBH (and Mann et al 2007) had incorrect geographic locations for numerous proxies. The same error is repeated in Mann et al 2008, a defect encountered by Jeff Id and myself in trying to replicate reported correlations to gridcell temperatures. Nearly 100 […]

Re-Visiting RegEM: Rutherford et al 2005

Mann et al 2007 is a new RegEM version, replacing the RegEM calculations of Rutherford et al 2005. The logic is not entirely self-contained and so I re-visited some of our previous comments on Rutherford et al here here here here . I’m going to reprise two issues today: Collation Errors, a small but amusing […]

Splicing in Rutherford et al 2005

Post Washington, I was browsing through the turgid prose of Rutherford et al 2005 – which actually uses the original MBH98 data set (PC series and all) for nearly half their analysis, they also consider the mystery Briffa et al 2001 sites, which they also do not reveal. The SI says – contact Tim Osborn, […]

Jean S on Rutherford et al 2005

Jean S has sent the following longer contribution on Rutherford et al 2005. I always appreciate Jean S’s thoughtful comments (which is no secret to readers here). So enjoy. JeanS: Now since the review of Burger and Cubash [BC06 here after] put Rutherford (2005) [R05] back on the table, there is an issue to which […]

Rutherford 2005 and the Divergence Problem

Rutherford et al 2005 (the et al being half the Hockey Team: Mann, Bradley, Hughes, Briffa, Jones, Osborn) is a re-statement of the MBH98 network (flawed PCs and all) and the Briffa et al 2001 network using RegEM. I haven’t figured out exactly what the properties of the RegEM method are as compared to other […]

Rutherford et al [2005] Collation Errors

I’ve got something that’s a little bit amusing today. In MM03, we pointed out collation errors in pcproxy.txt (which I’ve recently hypothesized was used in the version of Rutherford, Mann et al [2005] submitted in July 2003 and was laundered after MM03). We pointed out that the PC series all seemed to start one year […]

Rutherford, Mann et al [2005]

Over at Daily Kos, Mann says that the Nomads (this is a new candidate name for the Hockey Team) have moved on and that RegEM, as in Rutherford, Mann et al [2005], is the new sheriff. At the end of the day, it’s hard to see how the RegEM method avoids any of the BàƒÆ’à‚⻲ger […]
