The city's highest recorded temperature was 43.2 °C (109.8 °F) on Australia Day 1940 at the Brisbane Regional Office, [10] with the highest temperature at the current station being 41.7 °C (107.1 °F) on 22 February 2004; [11] but temperatures above 38 °C (100 °F) are uncommon.
Recent climate events such as extremely high temperatures and widespread drought have focused government and public attention on the effects of climate change in Australia. [8] Rainfall in southwestern Australia has decreased by 10–20% since the 1970s, while southeastern Australia has also experienced a moderate decline since the 1990s. [5]
An economic analysis of climate change uses economic tools and models to calculate the magnitude and distribution of damages caused by climate change. It can also give guidance for the best policies for mitigation and adaptation to climate change from an economic perspective.
Climate change has been a critical issue in Australia since the beginning of the 21st century. Australia is becoming hotter and more prone to extreme heat, bushfires, droughts, floods, and longer fire seasons because of climate change. Climate issues include wildfires, heatwaves, cyclones, rising sea levels, and erosion. [147] [148] [149] [150]
An atmospheric reanalysis (also: meteorological reanalysis and climate reanalysis) is a meteorological and climate data assimilation project which aims to assimilate historical atmospheric observational data spanning an extended period, using a single consistent assimilation (or "analysis") scheme throughout.
A model-based analysis of heat and drought conditions underlying these Australian bushfires found that anthropogenic climate change had caused the probability of extreme heat to increase by at least a factor of two, and the risk of a Fire Weather Index being "severe" or worse to increase by at least 30%.

The Special Report on Emissions Scenarios (SRES) is a report by the Intergovernmental Panel on Climate Change (IPCC) that was published in 2000. The greenhouse gas emissions scenarios described in the Report have been used to make projections of possible future climate change.
The City of Albany has not declared a climate emergency but has signed a climate action declaration with the goal of the City using 100% renewables by 2030. This document is similar to a climate emergency declaration but does not refer to climate change as an emergency. [113] No Armadale, City of: No: N/A: Yes Ashburton, Shire of: No: N/A: Yes
