Strange Happenings In Circleville, Ohio

The temperature record dies by thousands of small cuts.


By Paul Homewood

As a diligent accountant (!), I never trust anything, and like to double check. While I was working on the Ohio exercise, the adjustment for 1934 at Circleville stood out , so I decided to cross check against the USHCN station files.

At the end of each year, CDIAC update all of the USHCN station records, which can provide a variety of data.

The dataset for Circleville provides this list of the monthly temperatures after adjustment for 1934.


Meanwhile, the USHCN Final dataset, the one actually used by NCDC for national temperature calculations, gives us these figures. These are in tenths of a degree centigrade.


If we convert the first lot of temperatures into centigrade, and compare, we get:


The latest USHCN Final data are all about 0.4C higher than the station data. The suggestion is that the former has been altered since the station data…

Extreme Weather in 1759

A diary recording Bath’s weather, written by a clergyman about 250 years ago, has been found by archivists.


The parchment notebook belonged to Reverend Duel Taylor whose tiny writing recorded the city’s weather every day for six years between 1756 and 1761.


An entry in December 1759 shows extreme weather was not unusual with the the river “frozen so hard” people had to “walk across it for three days past”.


It was found among papers of Bath’s town clerks.

The Central England Temperature for December 1759 was 2.5C, about -2.1C below the 1961-1990 average.

Are Polar Bears Really Endangered?


Christina Wu at the Urban Times (July 3, 2014) recently asked this question. She came up with a surprisingly balanced argument but some predictable responses from IUCN Polar Bear Specialist Group (PBSG) biologists. As a consequence, she overlooked some critical facts that make a big difference to the answer.

Figure 1. Are polar bears really endangered? The US Fish and Wildlife Service thinks so, but only because Steven Amstrup, based on a computer model projecting sea ice out to 2050, said so (Amstrup et al. 2007). This information has been used by the Center for Biological Diversity and other NGOs, like WWF and Polar Bears International (where Amstrup is now employed), to solicit donations. Figure 1. Predictions of polar bear population declines by 2050 are being used by the Center for Biological Diversity, WWF and Polar Bears International to solicit donations.

Wu stated that, for the populations for which we have numbers (see my discussion here), polar bear populations have been increasing overall since the 1970s. She then asked:

“So if polar bear populations are increasing, what’s all the fuss about?”

She went to PBSG biologists for answers. She talked to Elizabeth (Lily) Peacock, now a medical student, and Geoff York, who is employed full time for the World Wildlife Fund (WWF). Apparently, they…
