Roger Pielke Jr has written a gracious post , following up on Bishop Hill’s post and considering the issues as they pertain to science policy, and, in particular, the processes of peer review and due diligence, which have informed many of my posts. He refers to and reconsiders a post that I wrote for Prometheus […]
Reader Perry writes in reporting an interesting narrative of the Caspar Ammann affair at Bishop Hill’s blog here. IT is a detailed narrative written in a lively style of a story that’s been followed here for a few years and re-visited last week with the release of the Ammann SI. The article is very flattering […]
When Wahl and Ammann’s script first came out, I was able to immediately reconcile our results to theirs – see here. As Wegman later said: when using the same proxies as and the same methodology as MM, Wahl and Ammann essentially reproduce the MM curves. Thus, far from disproving the MM work, they reinforce the […]
The Texas Sharpshooter fallacy is a logical fallacy where a man shoots a barn thirty times then circles the bullet holes nearest each other after the fact calling that his target. It’s of particular concern in epidemiology. Folks, you are never going to see a better example of the Texas Sharpshooter work itself out in […]
John A writes: I’ve installed the “unfancy quotes” plug-in which now means that code published on this blog can now be cut/pasted into R without any further messing about (try the code below, for example). For previous R codes, the plug-in does not change the fancy quotes, unless Steve just opens the post for edit […]
July monthly seaice data from NSICD is shown below. I have no idea how this reconciles to the JAXA versions that we’ve been following or to the daily binaries. Both extent and area are shown. The SH anomaly has declined markedly with SH winter and the GLB anomaly is slightly negative.
Briffa 2000 is one of the canonical “independent” reconstructions in the IPCC AR4 spaghetti graph, the Wikipedia spaghetti graph and similars. I’ve discussed it in the past, but I’m going to revisit this in light of the new information on Tornetrask and I’m going to run Brown’s inconsistency statistic on it. Briffa used 7 series: […]
We seem to be having occasional success in getting things archived. CSIRO was shamed into providing the data for their Drought Report and David Stockwell has now reported on this. Earlier this year, we reported a form of academic check kiting by Ammann and Wahl, where they had referred to Supplementary Information for key results, […]
David Stockwell has posted up an analysis of the CSIRO Drought Report, using the data grudgingly made public by CSIRO after public pressure. Key claims of the CSIRO report do not pass obvious statistical test for “significance”. Please visit David at his blog.
We keeping hearing the incantation from the Team that all the reconstructions on the Jesuit Index show a warmer modern than medieval period. I reported that I recently obtained a digital version of Grudd’s revised Tornetrask reconstruction and I’ve been anxious to test out its impact on the Jones et al 1998 reconstruction (together with […]
