Tropical Troposphere

Apr 26, 2008 – 12:16 PM

Last year, Ross McKitrick proposed the ironic idea of a “T3 Tax” in which carbon tax levels were related to observed temperature increases in the tropical troposphere. Temperature increases in the tropical troposphere are, as I understand it, a distinctive “fingerprint” for carbon dioxide forcing. Apparent discrepancies between a lack of warming in satellite data […]

Wilson in Kyrgyzstan

Apr 23, 2008 – 6:54 AM

Wilson et al 2007 (previously discussed here) considers a Kyrgyzstan series that has numerous issues – the usual provenance problems unfortunately occur once again. But over and above that, it uses multiple inverse regression, a procedure used all too casually by dendros. In this case, the procedure flips over one of the ring width series […]

GISS Adjusts the Heartland

Apr 10, 2008 – 1:10 AM

One of the surfacestations.org intrepid traveling volunteers, Eric Gamberg, has been traveling through Nebraska as of late, picking up stations as he goes. He recently visited the USHCN station of record, COOP # 256040, in North Loup, NE, not to be confused with Loup City, which he also visited. Records describe this station as being […]

L.A. Confidential

Mar 25, 2008 – 11:04 AM

Minus Kim Basinger. http://wattsupwiththat.wordpress.com/2008/03/24/how-not-to-measure-temperature-part-54-los-angeles-the-city/ As a reader at Anthony’s blog notes, there’s an interesting history here. Note that the temperature graphic shown linked at Anthony’s site is the version used by NOAA, rather than the version used by NASA. The differences are shown in the two graphs below. The NASA adjusted version increases past L.A. […]

PCs in a Linear Network with Homogeneous Spatial Autocorrelation

Mar 24, 2008 – 1:13 PM

As I observed a couple of posts ago, the Stahle SWM network can be arranged so that its correlation matrix is closely approximated by a Toeplitz matrix i.e. there is a “natural” linear order. I also noted that results from matrix algebra proving that, under relevant conditions, all the coefficients in the PC1 were of […]
