In case any of you have been wondering about my radio silence, I’m currently in Erice, Sicily, where I’ll be participating in an Erice seminar, which I was re-working most of last week. We left on Sat night and it takes a while to get here. We stopped in Palermo on the way. My topic […]
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 […]
After I posted GISS Spackle and Caulk, a number of commenters marveled at the symmetry of the histogram (GISS temperature estimate minus actual temperature). Some were dismayed that there was not a clear warming bias in the plot. Others were giddy for the very same reason. A few noted (as I hoped) that the differences […]
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 […]
Earlier this year I did a post on the amount of estimation done to the GHCN temperature record by GISS before generating zonal and global averages. A graphic I posted compared the amount of real temperature data with the amount of estimation over time. To read the graphic, consider 2000 as an example. As of […]
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: […]
