Last year, I reported on the resurrection of Chucky, with even Mann’s PC1, repudiated by Wegman and the NAS Panel, being illustrated in IPCC AR4. Chucky is back with a vengeance in the U.S. CCSP report, entitled “Unified Synthesis Product Report by the U.S. Climate Change Science Program and the Subcommittee on Global Change Research”, […]
Here’s a first attempt at applying the techniques of Brown and Sundberg 1987 to MBH99. The results shown here are very experimental, as I’m learning the techniques, but the results appear very intriguing and to hold some possibility for linking temperature reconstructions to known statistical methodologies – something that seems more scientifically useful than “PR […]
Introduction If one is to advance in the statistical analysis of temperature reconstructions, let alone climate reconstructions – and let’s take improving the quality of the data as the obvious priority – Task One in my opinion is to place the ad hoc Team procedures used in reconstructions in a statistical framework known off the […]
In 2000, Keith Briffa, lead author of the millennial section of AR4, published his own versions of Yamal, Taymir and Tornetrask, all three of which have been staples of all subsequent supposedly “independent” reconstructions. The Briffa version of Yamal has a very pronounced HS and is critical in the modern-medieval differences in several studies. However, […]
Bernie draws our attention to an article in the Globe and Mail on another break-off of the Ellesmere Island ice shelf: The Globe and Mail has an excellent map of the “collapse” of this ice sheet. Apparently its collapse has been proceeding for about 100 years. Update- The break is said to be unprecedented since […]
As noted by Pat Frank, Demetris Koutsoyiannis’ new paper has been published, evaluating 18 years of climate model predictions of temperature and precipitation at 8 locales distributed worldwide. Demetris notified me of this today as well. The paper is open access and can be downloaded here: http://www.tandfonline.com/doi/pdf/10.1623/hysj.53.4.671 Here’s the citation: D. KOUTSOYIANNIS, A. EFSTRATIADIS, N. […]
No single topic seems to arouse as much blog animosity as any discussion of Hansen’s projections. Although NASA employees are not permitted to do private work for their bosses off-hours (a currying favor prohibition, I suppose) – for example, secretaries are not supposed to do typing, over at realclimate, Gavin Schmidt, in his “private time”, […]
I’ve been trying for nearly a year to get a digital version of the Tornetrask reconstruction of Grudd (2008), also referred to in his thesis. Last week, Hakan Grudd sent me a digital version of the MXD series – hooray! Previously I’ve previewed this new version using clips from the articles or thesis e.g here. […]
First of all, the most important issue in this study is acknowledging Hennessy et al 2008. I had to agree to acknowledge them about 10 separate times to download data and so I do so. Acknowledging Hennessy et al 2008 seems to be more important to the authors than the results themselves. I hereby acknowledge: […]
Speaking of record handling, here’s a particularly amusing defence of scientists failing to maintain proper records over at Connolley’s: they are less lazy than filmmakers. Mosher noted that the irony of the thoroughness of the OFcom examination of Swindle records as compared to the haphazard and obstructive availability of data that we’ve seen too frequently […]
