In the discussion of the Tucson weather station, Ben Herman of the U of Arizona observed that there were serious biases with the HO-83 hygrothermometer – introduced in the early 1990s – which was said to be a contributor to the uptick to Tucson values. Although USHCN has implemented adjustments to U.S. data to deal […]
Here’s a discussion of replication policy posted up in the relatively early days of the blog, which I’ve re-posted in light of NASA spokesman Gavin Schmidt’s attempts to justify Hansen’s refusal to provide the source code used in his temperature calculations. It seems that these calculations are important enough to prompt a concern over the […]
Well before the current debate over the value of the near surface temperature record and its many possible biases, and well before Parker’s UHI studies sought to minimize the effect based on windy -vs- non windy days, J. Murray Mitchell published a paper in 1952 titled: On the Causes of Instrumentally Observed Secular Temperature Trends […]
Hansen has followed up his “Lights Out Upstairs” outburst with another outburst dismissing critics as “court jesters” with whom he will have no truck. (Lights Out is now cited on the NASA website.) His new jeremiad re-iterated the position of NASA spokesman Gavin Schmidt that U.S. errors “didn’t matter” because the U.S. was only 2% […]
NASA spokesmen Gavin Schmidt and James Hansen have observed that the US accounts for only 2% of the earth’s surface and conclude that problems in the US network don’t matter. There are only 6 Brazil stations in GHCN which have records extending through the 1930s and as late as 2004, which is an indication of […]
The NOAA website http://mi3.ncdc.noaa.gov/mi3qry/search.cfm? has a Map tab linking to local maps and Google Earth. I don’t recall seeing it before. Maybe someone can comment on this and also check the accuracy of the maps for stations shown there. I was looking to see if their equipment reporting included whether stations had aspirated or unaspirated […]
During the past 2 months, there has been an active discussion in the blogosphere about the quality of the Tucson U of Arizona weather station. While I have never claimed that the blogosphere is a substitute for academic journals, the thread of Tucson discussions seems to me to be a good example of internet discussion […]

The interview is here starting at 17:40 (just move the scrollbar to around 17:30, you don’t have to wait!). The interview is obviously edited, but Steve manages to make some clear points.
The new server hardware I built for Climate Audit was deployed in the co-location center today in California, I hand delivered it myself. This new server has much over the old one from a tech spec point of view, including faster CPU, dual core, error corrected memory, and hi speed SATA2 drives. It’s biggest advantage […]
