Nevertheless and as
with maxima but in a different way, the very rapid alteration in minimum
temperature differences and
averages in 1997 strongly suggests an artificial rather than natural influence corrupting Perth's
temperature record.
The sea level high - stand was associated
with the so - called Climatic Optimum or the Holocene Optimum, during 8000 to 4000 BC when
average global
temperatures reached their
maximum level during the Holocene and were warmer than present day.

average than those measured for a day ending in the early morning,
with the size of the difference varying from place to place.

Analysing the mean summer
maximum temperature differences between Bourke and Charleville, the unadjusted data (Figure 5) indicates that Bourke was, on
average, about 2 °C warmer prior to Stevenson screen installation in 1908 than it was in the years following that,
with wide year - to - year variations.
An Australian example is the comparison between a Stevenson screen and a Glaisher stand carried out between 1887 and 1947 at Adelaide (Nicholls et al., 1996), which found that
maximum temperatures in the Glaisher stand were about 0.6 °C warmer than those in the Stevenson screen as an annual
average,
with differences of about 1 °C in summer.

Menne compares one big
average of a whole bunch of stations
with another, concedes that differences in measuring devices may have introduced an error and that the distortion to the record may have occurred prior to the data series, but that one group shows more warming of the
maximum temperatures and more cooling of the minimum
temperatures, but more work should be done to confirm all this.
