I’m finding some benefit to having spent some time on station histories prior to my present re-visit to Mannian proxies. Digging into the handling of station histories gives some interesting perspectives on network handling that are worth considering for tree ring networks. For example, assume for a moment that North American tree ring chronologies used […]
Today I wish to re-visit an issue discussed in one of the very first CA posts: did MBH98 actually use the PC retention rules first published in 2004 at realclimate here and described both there and by Tamino as “standard” selection rules. Much of the rhetorical umbrage in Tamino’s post is derived from our alleged […]
Here is a little present for Jean S and UC. Something new from the gift that keeps on giving. Something that even I never noticed before. What we’re going to see is that in Mann-world, U.S. tree ring series are capable not merely of reconstructing world temperature, but 9 different “climate fields”. In effect, using […]
As noted previously, Tamino did not quote, cite or discuss how our articles reported key issues in his post – an omission that results in our research not being accurately represented in the record at Tamino’s site. I’ll discuss a couple of examples. It’s unfortunate that time has to be spent on such matters prior […]
One of Hansen’s pit bulls, Tamino, has re-visited Mannian principal components. Tamino is a bright person, whose remarks are all too often marred by the pit bull persona that he has unfortunately chosen to adopt. His choice of topic is a curious one, as he ends up re-opening a few old scabs, none of which […]
Anthony reports: Here is a link to the audio and the transcript of the radio interview I did with Glenn Beck on Monday at the International Conference on Climate Change in New York. http://www.glennbeck.com/content/articles/article/196/6727/?ck=1 For those that would like to see my slide show presented at ICCC that day, see this link: http://gallery.surfacestations.org/watts-NYC-2008/index.html UPDATE: The […]
During the past few days, I’ve been assessing the GHCN-Daily dataset, which is a very large data set and plan to do a number of posts on this topic, including a description of the data set. It turns out that literally hundreds of stations that expire around 1989 or 1990 in the NASA data set […]
I’ve been parsing through the NASA data set in order to evaluate the prevalence of NASA using obsolete data versions e.g. a Rurrenabaque version ending in 1989 when data is available to 2008). As I was doing so, I noticed that a surprising number (97) of NASA stations included in their inventory (http://data.giss.nasa.gov/gistemp/station_data/v2.temperature.inv.txt) appear to […]
On Feb 20, 2008, I wrote a post reviewing the provenance of various versions of an individual USHCN station (Lampasas), observing that a much more recent version was available at NOAA than at CDIAC) (the source used by NASA. I made the following recommendation: Regardless of whether these station histories “matter”, surely there’s no harm […]
