evidence: Both adjusted and unadjusted temperatures show that Australia’s climate has warmed since 1910. Since 1955 adjusted and unadjusted data are virtually identical. It is also during this time that most of the warming has occurred in Australia. [...] Australian mean temperature change over the last century is best represented by a bilinear model, with a period of relatively no change from 1910 through to 1950, followed by a period of relatively rapid warming from 1950 to present. When characterised this way, both adjusted and unadjusted data show virtually identical warming over this latter period. [...] While there is no significant trend in Australian temperatures prior to 1950 in either the ACORN-SAT or AWAP dataset, the difference in the adjusted and unadjusted climatologies for this period causes differences in the overall temperature change from 1910 to 2018. Taking a simple linear trend, Australia warmed by around 1.39 °C from 1910 to 2018 in the ACORN-SAT data, compared with a change of 0.89 °C in the AWAP data—a difference of around 0.50 °C in more than 100 years.
