Evasions and Fantasy at Real Climate

Several readers have asked me to respond to recent comments about me at Real Climate: briefly, Osborn has made one misrepresentation after another and made statements with seemingly complete indifference as to whether he has any basis for making the claims. In respect to Schmidt’s whinge, as Lucia sagely observed a couple of years ago […]

Treeline Changes and Altitude Inhomogeneity

The apparent inconsistency of ring width chronologies with analysis of changes in treeline elevation has long been an issue that I’ve urged specialists to address. Unfortunately Briffa et al 2013 failed to address the inconsistency at Polar Urals, even though they took note of an obsolete Shiyatov article on treeline changes. (More recent work by […]

Shiyatov and the Polar Urals

Nearly all readers agreed with the proposal (of my most recent post) for a comprehensive mapping and crossdating of all dead and living trees within one or more altitudinal transects in the Polar Urals, with the objective of achieving a crossdated dataset of at least 1000 subfossil trees and 500 living trees, each with accurately […]

An RC Question about Briffa et al 2013

A commenter at Real Climate asked the following interesting question about the Urals/Yamal area reported in Briffa et al 2013: So, for this region, what data do you wish you had, that could be plausibly gotten (i.e, not like 1000-year-old measured temperature records), that you don’t have? And why? Jim Bouldin of RC described the […]

Briffa Condemns Mann Reconstructions

Not in so many words, of course. However, Briffa et al 2013 took a position on the use of radially deformed tree ring cores that would prohibit the use of strip bark bristlecones in temperature reconstructions, thereby emasculating Mann’s reconstructions. And not just the Mann reconstructions, but the majority of the IPCC reconstructions used by […]

Briffa 2013

Briffa’s new paper on Yamal is online today here, together with Supplementary Information here. Yamal has been a longstanding issue at Climate Audit. The new article appears to be their long awaited response to criticism from Climate Audit (though this criticism is not referred to anywhere in the aticle.) In resisting FOI requests for their […]

Yamal FOI Sheds New Light on Flawed Data

Phil Jones’ first instinct on learning about Climategate was that it was linked to the Yamal controversy that was in the air in the weeks leading up to Climategate. I had speculated that CRU must have done calculations for Yamal along the lines of the regional chronology for Taimyr published in Briffa et al 2008. […]

Yamal and Hide-the-Decline

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 […]

CRU: “We had never undertaken any reanalysis…”

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 […]

McIntyre Submission with Figures

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 […]
