In recent years, Australia has experienced unprecedented heat, including heatwaves and record-breaking hot days, months, seasons and years. Australia has a naturally variable climate, but recent attribution studies show that our recent extremes are already being influenced by climate change. In this talk, I will investigate these human influences on past, present and future extreme climate events in Australia. How have recent hot extremes compared to cold extremes? Will future temperatures be more extreme and how so? Are recent extremes a sign of a new normal?
