Who wrote the EPA documents?

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 […]

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.

Mann 2008 – Replication II

Let’s continue Mann 2008 – Replication with EIV. To run regreclow.m and regrechigh.m you’ll need files climate, eofnumb, and proxyN, where N runs from 1 to 19. I’ve run prepinputforrecon.m with required folder structure (C:\holocene\s1\zuz10\work1\temann\ etc.) in my computer. After that I did run regrechigh.m in folder C:\holocene\s1\zuz10\work1\temann\zzrecon1209\nhnhscrihad\highf and regreclow.m in folder C:\holocene\s1\zuz10\work1\temann\zzrecon1209\nhnhscrihad\lowf The regem […]

Jean S on Rutherford et al 2005

Jean S has sent the following longer contribution on Rutherford et al 2005. I always appreciate Jean S’s thoughtful comments (which is no secret to readers here). So enjoy. JeanS: Now since the review of Burger and Cubash [BC06 here after] put Rutherford (2005) [R05] back on the table, there is an issue to which […]
