One of the main Hockey Team studies is Esper et al 2002, which is published in Science and, naturally, no data is archived. Esper has not deigned to reply to any emails by me requesting data. Esper and coauthors have just published an article in QSR leading with a discussion of the Mann controversy. I’m […]
As a result of refusals by Moberg, Sonchkin and Lauritzen, I’ve filed a Materials Complaint with Nature, which will hopefully result in the delivery of the data in less than geological time. In an email to me concerning a possible one year misdating of U.S. bristlecones, Moberg said that their "reconstruction does not contain any […]
Dmitry Sonechkin, the #2 author of Moberg, Sonechkin et al [2005], has replied that he cannot send the Indigirka series used in Moberg et al [2005] because the "series developers do not want to disseminate it. They say this series will be re-calculated soon to reject some errors in it (a general trend etc.)."
Anders Moberg sent a courteous response on the Lauritzen issue mentioned in More Moberg and Brandon Whitcher sent some comments on end effects in waveslim. Update Sep 7-8: I’ve been blown off totally so far by Moberg and Lauritzen in trying to obtain the digital data underlying the discrepant graphs.
Many of you read Moberg. Some of you probably saw the following diagram showing the re-combination from wavelets to yield the final reconstruction. It looks like an even more complicated method than MBH98 – "science moves on". Moberg Figure 2. So if I offered to show you plots of the wavelet decompositions of all 11 […]
When Moberg [2005] first came out, I posted up some first comments on it. I haven’t done anything on it since then, partly because of the amount of time responding to comment on our MBH articles, partly because I got stuck on some missing data sets. Hans Erren has a really neat method for digitizing […]
Although Science has nice policies on paper requiring data archiving, in practice, its climate authors are singularly poor about doing so. Esper et al [2002] has enough missing data to make it very difficult to get traction on it. Here’s a letter that I sent today to Science requesting that they take steps to get […]
Sometimes the Hockey Team baffles me. I was at Esper’s website and noticed Esper J, Neuwirth B, Treydte K (2001) A new parameter to evaluate temporal signal strength of tree ring chronologies. Dendrochronologia 19, 93-102. Something that looked pertinent. As a component of his estimate of signal strength, Esper applied a statistical procedure Gleichlàƒ⣵figkeit G […]
Carl Wunsch has an interesting new preprint entitled: Abrupt climate change. An alternate view at his website.
realclimate has posted up a discussion of a recent Brief Communications Arising in Nature by Muscheler et al., commenting on Solanki et al. [2004]. They haven’t posted up the Solanki et al. reply, which argues that Muschelerr et al. have screwed up their normalization. However here it is . There are two points of interest […]
