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 […]
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 […]
What is the standard deviation (variance) of an autocorrelated series? Sounds like an easy question, but it isn’t. This issue turns out to affect the spurious regression problem, so I’m posting up a short note on the problem. These issues are well-known in econometrics, where they have led to “heteroskedastic-autocorrelation consistent” estimators. There’s an interesting […]
Miller et al. [2004] studied fossil evidence of forest levels in 9 locations in the western U.S. over the past 3500 years, including Whitewing Mountain and San Joaquin Ridge, Inyo Craters Chain in the eastern Sierra Nevadas, near the bristlecones of the White Mountains (about which I’m going to post an interesting graphic on their […]
One of the reasons for my recent focus on Thompson is that he was one of the 20 "wise" [my term] men (and women) who wrote here to the Barton Committee deeply concerned about your approach and expressed their "hope that as a community, we can help your committee shape public policy in the light […]
It has been brought to my attention that Science has formal policies on data archiving. The author of the email, who requested confidentiality, argued that this disproved my statement: Having acknowledged that, the underlying issue is that Science does not seem to either have policies that require authors to archive data or administration practices that […]
