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 […]
There have been a couple of recent mentions of Besonen et al 2008 (including Ray Bradley) which discusses varve sediment thickness in Lower Mystic Lake, New England as a hurricane proxy, reported as a “1,000-year, annually-resolved record of hurricane activity from Boston, Massachusetts”. Before discussing the article, I checked to see whether any of the […]
CSIRO has done the right thing in respect to the drought data used in its recent report and an archive is now available. David Stockwell reports here. Update: I’ve now done a quick look at their supposed data archive http://www.bom.gov.au/climate/droughtec/download.shtml and it is far from clear that this is anything like an adequate data archive.
