In The Climate Files, Fred Pearce wrote: When I phoned Jones on the day the emails were published online and asked him what he thought was behind it, he said” It’s about Yamal, I think”. Pearce continued (p 53): The word turns up in 100 separate emails, more than ‘hockey stick’ or any other totem […]
At the close of Boulton’s April 9 interview with CRU, the only such interview relevant to the proxy reconstruction controversies that constitute 99% of the Climategate emails, Boulton asked CRU to comment on Ross McKitrick’s National Post op ed last October during Yamal. The response was given to Muir Russell on or after June 16 […]
A news release on a new tree ring study here (h/t Anthony Watts) reported a reconstruction maxing out in the mid-20th century, with the characteristic late 20th century divergence problem. Their results contrast with CRU’s notorious Yamal chronology: Following the summer temperature reconstruction on the Kola Peninsula, the researchers compared their results with similar tree-ring […]
It will take a while to parse Muir Russell. They’ve been working on it for 7 months and I’ve had it for a day. I’m going to place up notes on things as I notice them. At some point, I’ll try to pull together a longer response, but there are lots of interesting things as […]
Just before Climategate, we were reflecting on the apparent non-“robustness” of the Yamal chronology to inclusion of Khadyta data. Briffa’s response was that he could still “get” a HS by adding in Yadoyayakha and Porzayakha ring width data that hadn’t been used in Briffa (2000). As noted in other posts, Khadyta isn’t the only site […]
Here’s a Gazprom aerial photo which illustrates this better than 1000 words. (Yamal is the location of some huge Gazprom natural gas fields.) From the colors, I presume that the picture is taken in fall as the larch have changed color. Spruce do not appear to be in evidence here – they have a more […]
Contrary to a myth believed in by the climate science “community”, most recent multiproxy reconstructions are not “independent” – they merely recycle the same stereotypes with slightly different weighting methods. In an email (1140039406.txt) in which Briffa urges Overpeck not not to “over egg the pudding”, he stated: “Peck, you have to consider that since […]
As a spin-off from looking at Mann of Oak proxies, I did (what I regard) as a pretty bit of decoding of some measurement data in the Climategate documents. The Climategate directory documents/briffa-treering-external/stepan/ contains a large number of tree ring measurement files dated July 1996 (with the characteristic suffix .rwl) with 3-character labels, “ala” “all” […]
My submission to the UK Parliamentary Committee is here – this version excludes figures. Here is a pdf version with illustrations. In my situation – which is a little, shall we say, unique- it’s hard to figure out exactly where to start. So I tried to cover topics that I didn’t think anyone else would […]
In July 2003, Tim Osborn advised Tom Crowley that there were multiple versions of Yamal (and Tornetrask) and that he needed to contact Briffa prior to using: The other files are “tornad.rcs” and “yamal.rcs” which are RCS-standardised tree-ring width series. I would really strongly suggest that you contact Keith Briffa about exactly what these series […]
