The Hockey Stick in Art and Literature

One of Josh’s finest graphic flourishes: (h/t Bishop Hill and WUWT)

UC on Mannian Smoothing

Two comments from UC on smoothing CET using Mannian smoothing, a technique peer reviewed by real climate scientists (though not statisticians). I think these coldish years do matter, maybe now there will be some advance in smoothing methods. mike writes (1062784268.txt) ( I think this is somewhat related to CET smoothing (?) ) The second, […]

More Data Refusal – Nothing Changes

Phil Jones and his coauthors in the recent multiproxy study (Neukom et al 2011, (Climate Dynamics) Multiproxy summer and winter surface air temperature field reconstructions for southern South America covering the past centuries) did not archive proxy data in the Supplementary Information. Many proxy series used in the study are not otherwise publicly archived. I […]

Crowley’s Apology

Tom Crowley has asked that the following apology be published at Climate Audit for his 2005 EOS article, as well as a similar interview on BBC, both of which contained numerous untrue and damaging allegations against me. See the original EOS article is here , my rejected reply here, the underlying correspondence here with some […]

The C.E.T.

December values of the longest instrumental record in the world (CET – Central England) are just in. December 2010 was the second-coldest December in the entire history dating back to 1659 (including the Little Ice Age.) Only Dec 1890 was colder (by a slim 0.1 deg C). [Update” Paul Hudson While 2010 worldwide is nudging […]

NASA GISS – Adjusting the Adjustments

As a simple exercise, I quickly revisited the everchanging Hansen adjustments, a topic commented on acidly by E.M. Smith (Chiefio) in many posts – also see his interesting comments in the thread at a guest post at Anthony‘s, a post which revisited the race between 1934 and 1998 – an issue first raised at Climate […]

Travel

Away to Thailand to visit one of my sons. Will be away for a couple of weeks but will be online most of the time. 24-hour flight tomorrow. We’ll probably be the only people on the leg to Thailand with a snowboard – presumably not usual inbound luggage. For our daughter who’s visiting there for […]

McKitrick and Nierenberg 2010 Rebuts Another Team Article

McKitrick and Nierenberg 2010, rebutting Schmidt 2009 is in press at the Journal of Economic and Social Measurement. Schmidt (Int J of Climatology) 2009, which commented on McKitrick and Michaels 2007, was peer reviewed by Phil Jones (the puffball review is in the Climategate documents); McKitrick was not given a chance to comment. In contrast, […]

New Light on UHI

The “inquiries” into CRU, as is well known, did not examine CRU’s “science”. One of CRU’s main “contributions” is the “proof” by Jones et al 1990 that the development of urban heat islands contributed no more than ~0.05 deg C to measured 20th century land temperatures. This proof is an integral component in justifying CRUTEM […]

McShane and Wyner Discussion

McShane and Wyner, previewed in August, has now been published by Annals of Applied Statistics as a Discussion Paper here with an accompanying editorial by Michael Stein and discussions by 13 different groups (one of which is a short comment by Mc and Mc, with an excellent Rejoinder. BTW using Firefox, I wasn’t able to […]
