Australian climate cooling since 2012

Dataset shows no warming for 12 years and three months

Comparing the first and second halves of the time period from March 2012 to May 2024, Australia's climate cooled by 0.049C, according to the Australian Climate Observation Reference Network (ACORN 2.3) for land stations (Bureau of Meteorology data source).

This is a small decrease in Australian mean temperatures from March 2012 to May 2024 and might alternatively be described as a plateau.

The University of Alabama Huntsville satellite dataset for Australian lower troposphere anomalies (UAH 6.0) shows mean temperature warming of 0.071C when comparing the first and second halves of the period from March 2012 to May 2024.

From January 2013 to May 2024, ACORN shows mean temperature cooling of 0.082C and UAH shows Australian lower troposphere warming of 0.040C when averaging the first and second halves of this time period.

The ACORN dataset shows significant land surface warming since June 2023 and the UAH dataset shows significant warming of the lower troposphere since July 2023 - both potentially affected by the emergence of an El Nino in the Pacific Ocean, strong solar activity and abnormally high atmospheric moisture content due to the Hunga Tonga underwater volcanic eruption in December 2021.

The chart below is updated each month to track anomaly trends produced by both datasets.

These trends are worth monitoring as most Australian public policy is now based on the inaccurate premise that Australia's climate is warming rapidly.
