Climate change in Australia has been a critical issue 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.
Since the beginning of the 20th century, Australia has experienced an increase of over 1.4 °C in average annual temperatures, with warming occurring at twice the rate over the past 50 years compared with the previous 50 years. 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. Rainfall in southwestern Australia has decreased by 10–20% since the 1970s, while southeastern Australia has also experienced a moderate decline since the 1990s. Rainfall is expected to become heavier and more infrequent, as well as more common in summer rather than in winter. Australia's annual average temperatures are projected to increase 0.4–2.0 °C above 1990 levels by the year 2030, and 1–6 °C by 2070. Average precipitation in the southwest and southeast Australia is projected to decline during this time, while regions such as the northwest may experience increases in rainfall.
Climate change is affecting the continent's environment and ecosystems. Australia is vulnerable to the effects of global warming projected for the next 50 to 100 years because of its extensive arid and semi-arid areas, and already warm climate, high annual rainfall variability. The continent's high fire risk increases this susceptibility to changes in temperature and climate. Meanwhile, Australia's coastlines will experience erosion and inundation from an estimated 8–88 cm increase in global sea level. Australia's unique ecosystems such as the Great Barrier Reef and many animal species are also at risk.
Climate change also has diverse implications for Australia's economy, agriculture and public health.

Les controverses sur le réchauffement climatique concernent le débat public sur l'existence, les causes et les conséquences du réchauffement climatique. Les polémiques portant sur l'existence et les causes du réchauffement climatique furent particulièrement virulentes entre 2004 et 2010 environ, période pendant laquelle le grand public prend largement connaissance du problème posé.
