This biennial report on climate change finds that the variations Australia is experiencing include increased extreme heat events, warmer oceans, rising sea levels, changes in rainfall patterns, and a long-term increase in extreme fire weather and length of the fire season. These effects are predicted to continue in the decades ahead.

This review, commissioned after equipment at two locations (Thredbo and Goulburn) failed to record the temperature when it dropped below -10.4 degrees Celsius in July 2017, found that the site hardware was unsuitable at very low temperatures.

This fourth, biennial State of the Climate report draws on the latest monitoring, science and projection information to describe variability and changes in Australia’s climate, and how it is likely to change in the future.

Air and ocean temperatures across Australia are now, on average, almost a degree Celsius warmer than they were in 1910, with most of the warming occurring since 1950, according to this report. This warming has seen Australia experiencing more warm weather and extreme heat, and fewer cool extremes. Key points: Australia’s climate has warmed by...

The Australian Government commissioned the Bureau of Meteorology and the Commonwealth Scientific and Industrial Research Organisation (CSIRO) to undertake a climatic assessment of the likely future climate patterns and the current Exceptional Circumstances standard of a one-in-20-to-25-year-event.
