Peterson 2003 stated: Contrary to generally accepted wisdom, no statistically significant impact of urbanization could be found in annual temperatures. Last week, Peterson sent me a list of the 289 sites used in this study, together with the classification into urban and rural. As I noted previously, there are many puzzles in the allocation of […]
I posted up the list of 289 sites from Peterson 2003 purporting to show that the difference between “urban” and rural sites was negligible. (See related posts here and here.) As noted before, the definition of “urban” includes such metropolises as Wahpeton ND and Hankinson ND. Cottage Grove 1S OR is classified as “urban”, while […]
Eli Rabett and Tamino have both advocated faith-based climate science in respect to USHCN and GISS adjustments. They say that the climate “professionals” know what they’re doing; yes, there are problems with siting and many sites do not meet even minimal compliance standards, but Hansen’s software is able to “fix” the defects in the surface […]
Peterson (2003) online here is an influential study cited by IPCC AR4 purporting to show that the urbanization effect is negligible. It concluded: Using satellite night-lights—derived urban/rural metadata, urban and rural temperatures from 289 stations in 40 clusters were compared using data from 1989 to 1991. Contrary to generally accepted wisdom, no statistically significant impact […]
Obviously the big issue in climate is the impact of 2 times CO2. While my own issues tend to be statistical, this site obviously attracts many readers who want to jump straight to discussion of thermodynamics and theories of atmospheric physics. Articles like G and T obviously inflame such tendencies. For some reason, people who […]
There is some recent discussion of Marysville and Orland at Eli Rabett and Tamino. The gist of their arguments is that the failure of NOAA to implement their promised quality control doesn’t “matter” since the problems get adjusted out in the adjustment software so that trends at Orland end up being similar to trends at […]
Eli (RTFR) Rabett, has a new defence of GISS adjustments, arguing that we should simply trust the clergy at GISS. Eli seems to be particularly prickly when it comes to anything that could be construed as criticism of GISS. (BTW Roger Pielke Jr and others have said that Eli is a pseudonym for Josh (RTFR) […]
On July 17, 2007, Rob Wilson archived British Columbia measurement data obtained in 1997-1998 and used in Wilson and Luckman 2002, 2003 (20 ring width; 7 mxd series). The data is here: ftp://ftp.ncdc.noaa.gov/pub/data/paleo/treering/updates. Wilson et al (JGR 2007), a new article, reports on a new tree ring reconstruction from 1750 on, which Rob claims to […]
Lonnie Thompson’s work is prominently cited by Al Gore, was cited by the NAS panel of Surface Temperature Reconstructions and is used both in temperature reconstructions and in articles arguing that there was no MWP. One of the remarkable aspects of Thomspon’s corpus is both that the original sample data is unarchived – even for […]
A Tucson climate scientist commenting on the location of the University of Arizona weather station in parking lot acknowledged that: It’s true that situating a weather station in a parking lot is not the best location. An understatement to day the least. He argued against locating the weather station on a nearby lawn: The emissivity […]
