Varved Inconsistency

Since AR4, there have been a series of new multiproxy studies, several of which were cited in AR5 (Mann et al 2008; Ljungqvist et al 2010; Christiansen and Ljungqvist 2012; Shi et al 2013). A distinctive feature of these and other recent multiproxy studies is the incorporation of varve thickness and near-equivalent mass accumulation rate […]

Tingley and Huybers: Varve Compaction

Specialist literature on varves e.g. Besonen et al 2008 – coauthor Raymond Bradley -(which is cited by Tingley and Huybers) make the obvious observation that varves are compacted within a core. Besonen et al 2008 allow for compaction by estimating annual mass accumulation as a more appropriate measurement of varve “thickness”, rather than uncompacted varve […]

More from the Junior Birdmen

A new paper in Nature by Tingley and Huybers h/t WUWT. In keeping with the total and complete stubbornness of the paleoclimate community, they use the most famous series of Mann et al 2008: the contaminated Korttajarvi sediments, the problems with which are well known in skeptic blogs and which were reported in a comment […]

Say My Name – February Rerun

Science has published a Correction and Clarification to Kaufman et al (2009), see here. Since they only needed to correct four out of 23 proxies, there is no need to name those who pointed out errors. ;) There is a small improvement over the draft version though; congratulations Hu! We thank H. McCulloch and others […]

Another Correction from Upside Down Mann

After a year of stonewalling, Mann has published an update at his “grey” Supplementary Information (not yet reported at PNAS) in which he acknowledges an “error” in his figure S8a as follows: UPDATE 4 November 2009: Another error was found in the corrected Supplementary figure S8a from December 2008: The previously posted version of the […]

Connolley Endorses Upside Down Mann

Kaufman’s grudging acknowledgement (see their draft Corrigendum) that they used the Tiljander proxies upside down has not convinced the Team that the identical orientation of the Tiljander proxies in Mann et al 2008 was also upside down. There has been an active new round of debate in the blogs, with William Connolley endorsing Upside Down […]

The Kaufman Corrigendum

In a draft Corrigendum dated Oct 10, 2009 (most recently modified Oct 21, 2009), Kaufman gives what is obviously a warm and heartfelt shout-out in which they: thank those who have pointed out errors and have offered suggestions. More later today. [Note: see Sep 15 post here here for a preliminary assessment of Kaufman using […]

Upside-Side Down Mann and the “peerreviewedliterature”

In Andrew Revkin’s recent blog posting, he made the following observation about blogs, referring in particular to Climate Audit: What is novel about all of this is how the blog discussions have sidestepped the traditional process of peer review and publication, then review and publication of critiques, and counter-critiques, by which science normally does that […]

Atte Korhola: political and social playground

There is an interesting, and, in my opinion, very bold,  comment (dated 9/27, here in Finnish; Google Translation) in a Finnish web journal by professor Atte Korhola entitled “Recession in Climate Science”. Korhola: Esitän kärkeen heti teesin, jonka mieluusti alistan julkiseen kritiikkiin: kun myöhemmät polvet tutustuvat ilmastotieteeseen, he luokittelevat 2000-luvun alun tieteen historian noloihin lukuihin. […]

Kaufman and Upside-Down Mann

Kaufman et al (2009), published at 2 pm today, is a multiproxy study involving the following regular Team authors: Bradley, Briffa (the AR4 millennial reconstruction lead author), Overpeck, Caspar Ammann, David Schneider (of Steig et al 2009), Bradley as well as Otto-Bleisner (Ammann’s supervisor and conflicted NAS Panel member) and “JOPL-SI authors” who are various […]
