This is the first “city” study I put online in 2000. There is nothing isolated about Jones using a city with such obvious UHI contamination as Atlanta, they used hundreds of cities.
In the face of this methodology, the AMS journal in 1986 published not ONE comment and I am not aware anybody tried to comment. I look forward to hearing some justifications from IPCC supporters for the use of Atlanta and similar data to contribute to an accurate measure of global temperature trends.
The Oldham Skeptic has sent in more information for Coolwire 16 based on the latitude where Nansen moored his ship the Fram to pack ice north of Siberia in September 1893. Maps of the median sea ice edge for 1979 to 2000 suggest that Nansen may not have been able to drive the Fram as far north in modern times.

A scientist wonders
In your September issue Pete Hodgson wrote about “The Kyoto Question”: “The scientific argument is over and the world, with the Kyoto Protocol as a starting point, is beginning to act”.
One wonders where Hodgson got his scientific advice. The scientific argument is far from over.
I am a geologist and paleoclimatologist belonging to an international discussion group where about 250 well-qualified scientists discuss the science behind Kyoto in great depth. Most of these scientists are highly critical of the politicisation of the climate change discussion, as highlighted by the actions of the UN International Panel on Climate Change (IPCC).

Interesting commentary on 6 Dec 2005 from the Canadian Broadcasting Corporation’s journalist Rex Murphy who says, “Perhaps Kyoto is Japanese for hypocrisy.”:
REX MURPHY (Commentator): It’s been a strange week. I’ve been wondering why the global warming conference in Montreal is getting relatively little attention. Probably because of the cold weather. It’s odd for another reason. Ten thousand people have come to Montreal, ten thousand. For a conference on reducing energy consumption. Now, ten thousand is a large number, elephantine, in fact. I don’t suppose many delegates walked. As conferences go, this one is a real Leviathan. Just think of the Montreal summit’s ecological footprint.

Perth uses approximately 300GL of water PA.
The Govt. is constructing a ~$400Mill seawater desalination plant to produce 45GL PA.
In 2005 May to October (the runoff season) Perth dam catchments which total 3500 squ. kms had circa 958mm of rain. This equates to about 3353GL water falling free into catchments of which approx. 115GL flowed into dams, meaning that catchment efficiency (yield) was 3.4%.
My graphic at the Perth Water Users web site shows that up until the mid 1990’s catchment efficiency was 5.5 to 6%. Let’s just assume for a minute that our Governments had been sensible and maintained catchment management work, keeping yields this year at say 5.7%. An increase of 2.3% (5.7-3.4) in this years yield would have put an extra 75+ GL (2.3% of 3353 GL) into our dams, which is 160% of the projected production from the Kwinana Desalination Plant (KDP), where costs have already blown out to over $387Million.
There seems to have been little net change in Antarctic sea ice extent over a century in the South Atlantic, according to US Navy satellite maps which show the ice edge in the South Sandwich Islands group on the 4th December. This is close to where Sir Ernest Shackleton encountered sea ice in his ship Endurance in early December 1914.

Station temperature records are examined in nine five-by-five degree grid cells in the former USSR claimed by Karl 1998 to have warmed by circa 2 degrees over the period 1901-1996. Karl’s results, derived from updated Jones 1994 grid point data, are compared with temperature records from the Jones 1994 global update, the V2 GHCN and the NASA GISS website. In no grid cells are rural station records found to justify the warming claimed in Karl 1998. In three grid cells, stations with warming trends close to the Karl 1998 anomaly magnitudes are found, but in all three cases cities are the source of the apparent warming, which is not apparent at nearby small town or rural stations. The other six grid boxes contain either stations not warming at the rate suggested in Karl 1998, or very incomplete data for the 1901-1996 period. Station-by-station comparisons in all grid boxes show significant trend differences between Jones 1994 and GHCN/GISS data. In recent years it has become apparent that a sizeable share of century-long "global warming" is in the region of the former USSR. This paper examines at the level of individual weather station records the evidence for the claim in Karl 1998 of circa 2 degrees warming during 1901-1996 in nine grid boxes in Siberia and eastern Kazahkstan. Karl’s 1998 paper contributed to the IPCC publication "The Regional Impacts of Climate Change". Similar global maps of grid box anomalies are seen in the IPCC 2001 Third Assessment Report (TAR) Figure 2.9
Jones et al trends in South Africa are even more dominated by cities than their Australian data.
In 1991 I started hunting down temperature data that was not used by Jones et al 1986 and this lead to me contacting the South African ‘Weeburo” late in 1991 by mail. Despite considerable turmoil in that country I had the luck to encounter a helpful official who mailed me back a couple of diskettes with rural and small town data from 1960-1990.
This lead to the 1996 paper with Professor Robert C. Balling Jr., of Arizona State University which was posted online years ago by the late John Daly.

The paper demonstrates large differences between rural trends and the Jones et al trends dominated by cities.
Of course hugely ignored in IPCC circles. After 1991 I tried to obtain longer term S.A. data but co-operation stopped after they were contacted by BoM people. We know how it works.
In 1991 the writer (WSH) reviewed the Jones et al temperature data for Australia along with a wider selection of Australian data while associated with the Tasman Institute in Melbourne. The Executive Summary of that unpublished report which was circulated to interested parties, has survived in digital form and is presented here for the first time.
[Note, the Tasman Institute was a free market think tank in Melbourne for about a decade, closing in the late 1990’s.]
