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. They have diagnosed a downward bias in recent HadCRU results. On previous occasions, I’ve observed that the community is more alert to errors that go the “wrong way” than to errors that go the “right way” and this opinion remains unchanged. As noted in my previous post, it doesn’t appear to me that their slight upward revision in temperature estimates has a material impact on the discrepancy between models and observations – a discrepancy which remains, despite efforts to spin otherwise.
In today’s post, I’ve re-examined Robert Way’s contributions to the secret SKS forum, where both he and Cowtan (Kevin C) have been long-time contributors. In my first post, I took exception to Way calling me a “conspiracy wackjob”. However, relative to the tenor of other SKS posts in which their colleagues fantasize about “ripping” out Anthony Watts’ throat and Anthony and I being perp-walked in handcuffs, Way’s language was relatively mild.
In addition, re-reading the relevant threads, other than a couple of occasions (ones to which I had taken exception), Way’s language was mostly temperate and well-removed from the conspiratorial fantasies about the “Denial Machine” that pervade too much of the SKS forum. In addition, this re-reading showed that, on numerous occasions, Way had agreed with Climate Audit critiques, sometimes in very forceful terms and usually against SKS forum opposition. Way typically accompanied these agreements with sideswipes to evidence his disdain for Climate Audit, but seldom, if ever, contradicted things that I had actually said.
I think that readers will be surprised at the degree of Way’s endorsement of the Climate Audit critique of Team paleoclimate practices.
