I’m not sure McIntyre knows what ‘splicing’ is. To me it means cutting and joining two ends together. All Mann did was plot instrumental temperatures on the same axes, but he showed the whole record. Dana Nuccitelli There still seems to be a lot of confusion among Mann’s few remaining supporters as to why Phil […]
Today I will review the timeline of the above WMO 1999 graph in the light of the ClimateGate (CG) letters. The main events took place on Tuesday, November 16th, 1999. Things start rolling 9 AM (UK time), when Tim Osborn sends the new Briffa and recalibrated Jones (1998) time series to Phil Jones along with […]
PCA was also performed on certain proxy sub-networks (spatially dense regional networks of tree-ring data available separately in different continents) as means of dimensional reduction of the predictor network. In this case, the procedure was performed separately for each independent step of the stepwise calibration/reconstruction procedure described in “3” below. A decreasing number of PCs […]
This post is rather technical, and it is intended mainly for the historical completeness. So unless you are very, very interested in the tiny technical details of the HS saga, you can safely skip this. As most readers are aware, and stated in my post few hours after CG broke out, Mike’s Nature trick was […]
Jean S writes (transferred from a comment with the addition of a few headings): A question for the experts: is it known who wrote and who were used as experts in the EPA documents? If not, is that information considered public (i.e., obtainable under FOIA or similar)? The reason I ask is that I get […]
[Update 04/08/13: Josh has once again a brilliant view what’s going on here and in some other cases. Enjoy! ] No researchers in this field have ever, to our knowledge, “grafted the thermometer record onto” any reconstruction. It is somewhat disappointing to find this specious claim (which we usually find originating from industry-funded climate disinformation […]
Michael Kottek writes in the comment section: The results of my FOI request to the University of Melbourne can be seen here: http://tinyurl.com/96ey5dt I requested all correspondence between the authors and the journal regarding the paper. The referees reports were exempted as were documents relating to the resubmitted paper. I also requested correspondence between the […]
(This post is by Jean S.) A few days ago Steve discussed Raymond Bradley’s objection to use of the Yang Chinese composite reconstruction in the Mann et al Eos-response to Soon & Baliunas (2003). Bradley called the series “crap”, and demanded it to be removed from Figure 2 in the Eos article. It is not […]
A year and half ago Steve recalled some encounters with NASA GISS. One could imagine that after all that embarrassment the quality control in GISS temperature products was by now highly improved. One could be also wrong. In the March 2010 GISS temperature anomaly map Finland appears as a “hot spot” surrounded by cold temperatures: […]
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 […]
