In August 2008, in the early days of this blog (rightwinggranny.com), I posted an article about surface stations–the measuring devices used to calculate changes in the earth’s temperature. The article linked to a website called surface stations.org, which posted pictures of various surface stations used to measure global temperatures.
The location of the air conditioning exhaust and the cell tower might have something to do with how the temperature at this particular surface station seems to be increasing.
Well, a few years later, a scientific type (which I am definitely not) has done further research.
A reanalysis of U.S. surface station temperatures has been performed using the recently WMO-approved Siting Classification System devised by METEO-France’s Michel Leroy. The new siting classification more accurately characterizes the quality of the location in terms of monitoring long-term spatially representative surface temperature trends. The new analysis demonstrates that reported 1979-2008 U.S. temperature trends are spuriously doubled, with 92% of that over-estimation resulting from erroneous NOAA adjustments of well-sited stations upward. The paper is the first to use the updated siting system which addresses USHCN siting issues and data adjustments.
The new improved assessment, for the years 1979 to 2008, yields a trend of +0.155C per decade from the high quality sites, a +0.248 C per decade trend for poorly sited locations, and a trend of +0.309 C per decade after NOAA adjusts the data. This issue of station siting quality is expected to be an issue with respect to the monitoring of land surface temperature throughout the Global Historical Climate Network and in the BEST network.
This is the image that appears in the article along with the Press Release:
I am not a scientific type. I do not claim to fully understand what I have read in this article or even what is shown by the pictures. I strongly suggest that you follow the link to WattsUpWithThat and read the article for yourself. I am pretty good at bottom lines, though, and the bottom line here seems to be that global warming is not happening at the frightening rate that we have been told it is happening. We can now all take a deep breath and continue on with life as we know it. I strongly suggest that we do try to be stewards of our beautiful planet, but I also strongly suggest that we don’t overreact to the fear mongering that has been going on in recent years.
In 1975 Newsweek warned us of the “Coming Ice Age.” Now we are warned of the global warming catastrophe. I think we can safely conclude that scientists really don’t know as much as they think they do.
