2017 was Australia's third-warmest year on record (the national observational dataset commences in 1910). Australia's area-averaged mean temperature for 2017 was 0.95 °C above the 1961–1990 average. Maximum temperatures were the second-warmest on record at 1.27 °C above average, coming in behind +1.45 °C in 1998. Minimum temperatures were 0.62 °C above average, the 11th-warmest on record.
The 11-year mean temperature for 2007–2017 was the highest on record at 0.61 °C above average. Seven of Australia's ten warmest years have occurred since 2005 and Australia has experienced just one cooler than average year in the last decade (2011). Background warming associated with anthropogenic climate change has seen Australian annual mean temperature increase by approximately 1.1 °C since 1910. Most of this warming has occurred since 1950.
