QUOTE: In Deniliquin and Bathurst, there has actually been a fall in
temperatures over the last 100 years; but in many other regional places
there was just no trend, up or down.
Weather observatories in Australia, dating back 100 years or more, show
cities getting hotter as they get bigger; but country towns have generally
not been warming up.
Some have actually been cooling down.
Most scientists recognise that temperature measurements in cities are
influenced by non-climate things such as air-conditioners.
The cities in Australia also show the same trend as cities in the northern
hemisphere with the rate of warming here being less 1°C per century.
So the countryside has not been warming up, whereas cities are getting
hotter.
Substantial increases in carbon dioxide levels have been observed over this
period, so if CO2 really was driving temperature upwards, we would expect a
general rise in temperature in the bush and an even bigger rise in cities
due to the combined effect of CO2 and non-climatic heating.
In many parts of the world, it's hard to separate these two effects, so we
are lucky here in Australia to have records from isolated country locations
that are "un-contaminated" by the big city "heat island" effect.
The Australian Bureau of Meteorology (BOM) provides historical weather data
on the internet (URL: www.bom.gov.au/climate/data/weather-data.shtml ).
The average of the peak temperatures for each month is available and this
has been plotted in the attached graphs.
Graphs for the mean daily peak temperatures in January are shown for Echuca,
Deniliquin and Bathurst - as examples of country sites.
The last graph is for Sydney and shows evidence of the "big city warming
effect".
In Deniliquin and Bathurst, there has actually been a fall in temperatures
over the last 100 years; but in many other regional places there was just no
trend, up or down.
E M Smith reports a similar pattern of "no warming" based on a large number
of world-wide locations used by the IPCC.

"It is a remarkable fact that despite the worldwide expenditure of perhaps
US$50 billion since 1990, and the efforts of tens of thousands of scientists
worldwide, no human climate signal has yet been detected that is distinct
from natural variation."
