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 […]
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”, […]
