Clearly distinguished

[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 […]

Gergis et al Correspondence

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 […]

Moderate Low Weight

(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 […]

GISS: Warmest March ever in Finland

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: […]

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 […]

The Hockey Stick and the Milankovitch Theory

The 20th century warming counters a millennial-scale cooling trend which is consistent with long-term astronomical forcing. MBH99 According to the UMass researchers, the 1,000-year reconstruction reveals that temperatures dropped an average of 0.02 degrees Celsius per century prior to the 20th century. This trend is consistent with the “astronomical theory” of climate change, which considers […]

Yet another Upside Down Mann out

Science published today yet-another-Mann-et-al-reconstruction: Michael E. Mann, Zhihua Zhang, Scott Rutherford, Raymond S. Bradley, Malcolm K. Hughes, Drew Shindell, Caspar Ammann, Greg Faluvegi, and Fenbiao N: Global Signatures and Dynamical Origins of the Little Ice Age and Medieval Climate Anomaly, Science 326 (5957), 1256. [DOI: 10.1126/science.1177303]. Seems to me that Mann has re-discovered the Medieval […]

Mike’s Nature trick

So far one of the most circulated e-mails from the CRU hack is the following from Phil Jones to the original hockey stick authors – Michael Mann, Raymond Bradley, and Malcolm Hughes.

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. […]
