Here is this week's station of the week from the Idsos'
cherry picking of the RAW U.S. HCN data. It's the same old
story, the data isn't corrected for known influences.
************************************************** *****
*USHCN Temperature Record of the Week: Cadiz, Ohio
*
* To bolster our claim that "There Has Been No Net Global
* Warming for the Past 70 Years," each week we highlight
* the temperature record of one of the 1221 U.S.
* Historical Climatology Network (USHCN) stations from
* 1930-2000.
*
* This issue's temperature record of the week is from
* Cadiz, Ohio. During the period of most significant
* greenhouse gas buildup over the past century, i.e.,
* 1930 and onward, Cadiz's mean annual temperature has
* cooled by 0.79 degrees Fahrenheit. Not much global
* warming here!

Cadiz, Ohio is another small town surrounded by what were
once farm lands settled at the start of the U.S. expansion
westward. However, Cadiz is now in the center of a coal
mining region and the local hills have been extensively
strip mined. The result is likely to have been major
changes in vegetation cover, first, as the land was cleared
for farming, then stripped to obtain coal, then the stripped
areas allowed to recover in new vegetation.

The station history thru 1995 shows an interesting fact.
From 1903, when the record began to 1995, there were only 2
observers. The first lasted from 1903 until April 1955
(that's 52 years!!!), the second continued after that
(another 40+ years!!). Looking at the Idsos' graph, there
appears to be a step cool bias in 1955, about the data of
the change in observers. The time of observation was in the
evening, first 6 PM, then 8 PM, then 10 PM. The next
observer took data at 5 PM for a number of years until 1987,
after which the data was collected at 8 AM. Also in 1987,
there was a change in instrument type.

Once more, we find data which may (or may not) represent a
cooling trend, given the drastic change in the surroundings
and the time of day shift in 1987. Go figure.....
