Gergis2K and the Oroko “Disturbance-Corrected” Blade

Only two Gergis proxies (both tree ring) go back to the medieval period: Oroko Swamp, New Zealand and Mt Read, Tasmania, both from Ed Cook.  Although claims of novelty have been made for the Gergis reconstruction, neither of these proxies is “new”, with both illustrated in AR4 and Mt Read being used as early as Mann et al 1998 and Jones et al 1998.

Cook’s Fake Ethics Approval

For over a year, John Cook and the University of Queensland have repeatedly refused Richard Tol’s requests for information on rater ID and timestamps for the SKS ratings for Cook et al 2013. Recently there have been two events that shed new light on the dispute. First, in mid-May Brandon Shollenberger located the requested information online without password protection, which he placed online a few days ago.

Behind the SKS Curtain

As a preamble and reprise, I think that it is reasonable for Cowtan and Way to take exception with HadCRU’s failure to estimate temperature in Arctic gridcells and to propose methods for estimating this temperature. At a time when the climate community argued that differences between the major indices and accessibility to CRU data didn’t “matter”, I thought that both mattered. One of the reasons for transparency in CRU data and methods was so that interested parties could carry out their own assessments, as Cowtan and Way have done.
