Australia - Mean Temperature Deciles

Data collected and analysed by the Bureau of Meteorology show that 2014 was Australia’s third-warmest year on record while rainfall was near average nationally.

Nationally, Australian temperatures have warmed approximately one degree since 1950, and the continued warmth in 2014 adds to this long-term warming trend.

Simply the single most pressing and present public policy issue of our time. Yes, that is not the first time I have said that in the last eight years.

  • Another year of persistent warmth; spring was the warmest on record nationally, with autumn the third-warmest on record
  • Overall, 2014 was Australia’s third-warmest year on record: the annual national mean temperature was +0.91 °C above average
  • All States, except the Northern Territory, ranked in the four warmest years on record

Global Averages

The World Meteorological Organization (WMO) produce an estimated global mean temperature based on the average of three global surface climate datasets: those maintained by the UK Met Office Hadley Centre (HadCRUT4), the US National Climatic Data Center (MLOST) and the NASA Goddard Institute of Space Studies (GISTEMP).

Global Temperature Mean

Based on preliminary data (January–November), the estimated global mean temperature for 2014 is 0.57 ± 0.10 °C above the 1961–1990 average. Using this three-dataset method, 2014 is likely to be the warmest year on record (global observations commence in 1880).

No year since 1985 has observed a below-average global mean temperature and all of the ten warmest years have occurred between 1998 and the present.
