Ryan O has produced a very interesting series of Antarctic tiles by calculating Steigian trends under various settings of retained AVHRR principal components and retained Truncated Total Least Squares eigenvectors (Schneider’s “regpar”). The figure below re-arranges various trend tiles provided by Ryan in a previous comment, arranging them more or less in increasing retained AVHRR […]
Ryan O has observed a remarkable property of the Mannian algorithm used in Steig et al’s Antarctic temperature reconstruction described in a lengthy post at Jeff Id’s here and cross-posted at Anthony’s. Source code here (the source code style BTW evidencing engineering tidiness from which we should all take heed). I’m reporting here on one […]
Readers have sometimes proposed that I try to enlist the support of a British MP for efforts to get information from the various stonewalling UK climate institutions, such as Fortress CRU. In fact, it seems that British MPs have had their own personal reasons for not supporting FOI. For the past 5 years, they have […]
A shout out for Bob Tisdale’s blog here. Bob cross-posts at Anthony’s from time to time. At his own blog, he’s done a number of excellent analyses of SST data sets. On many occasions, I’ve observed that critical analysis of the temperature record has spent a disproportionate amount of attention on land data sets relative […]
With the North Atlantic hurricane season officially starting in a couple weeks (June 1), but possibly getting a head start with a developing low-pressure system in the Bahamas, considerable attention will be paid by the media to each and every storm that gets a name. In the North Atlantic, a name is granted to a […]
Rather than spending time archiving information from his various publications, Santer has placed his scientific priorities on introducing a remarkable cartoon (Youtube here), which ends (see 7 minutes on) with a ditty urging its audience to “do something about the power of poop”. The video ends with a close-up of a large odiferous dropping, with […]
As noted in an earlier post, I’ve now managed to synchronize 48 of 49 Santer tropo series with KNMI surface temperature series and have looked at versions of some key figures in CCSP 1-1 and previously inaccessible figures in Santer. First here is an important figure from CCP 1-1 showing a histogram of relative trends […]
Have any of you seen any articles discussing which model runs are archived? It doesn’t appear to me that all model runs are archived. So what criteria are used to decide which model runs are archived by the modelers at PCMDI? (This is a different question than IPCC selections from the PCMDI population.) We’re all […]
Lucia did a recent post on the construction of IPCC Figure 9.5, which I’d also been looking at in light of the Santer model information but I had different issues in mind. IPCC Figure 9.5 says that they extended selected 20th century runs (the “20CEN” models) with A1B models in order to produce the graph […]
The new USHCN was scheduled to come out a couple of years ago. A paper describing it has finally appeared, discussed by Pielke Sr here. I haven’t reviewed the new paper – something that I’ll be looking for is whether they rely on “homemade” changepoint methods to supposedly achieve homogeneity – “homemade” in the sense […]

FOI and the "Unprecedented " Resignation of British Speaker
Readers have sometimes proposed that I try to enlist the support of a British MP for efforts to get information from the various stonewalling UK climate institutions, such as Fortress CRU.
