One of the reasons that I’m going to parse through Esper’s Gotland series is the virtual absence of archived RCS chronologies, despite the fact that they are sweeping the field in multiproxy studies. Continuing on with Esper’s Gotland series First (and this is not shown by Esper) is a simple histogram of RWM and MXD […]
An important new proxy series, which is one of only 8 in Mann and Jones [2003] and one of only 11 low-frequency proxies in Moberg et al [2003], is the Chinese composite of Yang et al [2003]. Unlike the Hockey Team, Prof. Yang promptly provided the underlying data set upon request. Here are some early […]
Just as an experiment, I plotted up all the ring widths for the Gaspé and Polar Urals sites, with each core displaced a little. What I was thinking of the type of graph that you see in seismic surveys. The look is interesting, given how much weight is placed downstream on these data sets in […]
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 […]
We get considerable criticism from paleoclimate scientists that complying with requests for data and methods sufficient to permit replication is much too onerous and distracts them from "real work". However, the problem is not our request, but that any request should be necessary in the first place. In my opinion, a replication package should have […]
Last year, I presented a paper at the AGU Fall Meeting (December 2004) which was the core of our GRL paper. I’ve just submitted an abstract for the 2005 Fall Meeting for session PP-19 co-chaired by Hans von Storch.
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 […]
