What the data mean
The maps show that annual mean temperatures across Australia have increased over the reporting period, 1910 to 2004. In particular, temperatures have increased on average more than 0.1 degrees per ten years in South Australia, south-east Queensland, parts of the Northern Territory, Western Australia and Queensland. The second map shows the changes including 2005. The minor change since 2004 has not been analysed.
Increases in both maximum and minimum temperatures also indicate a general warming.

Issues for which this is an indicator and why
Atmosphere — Climate variability and change - Weather
Trends in temperatures and their spatial distribution are an indicator of climate variability and change, which in turn have an impact on our human, economic and environmental health.
Other indicators for this issue:
- A-01 Annual variation in the Southern Oscillation Index
- A-02 Rainfall trends - annual mean rainfall
- A-03 Rainfall extremes - inter-annual variations in annual extreme rainfall
- A-04 Temperature trends - annual mean temperature anomalies
- A-05 Temperature extremes - percentage area of extreme annual mean temperatures
- A-06 Extreme weather-related effects - cost of weather-related disasters
- A-36 Rainfall extremes - percentage area experiencing extreme wet and dry conditions
- A-47 Rainfall deficiencies - drought
