2021 Adequate confidence The impacts of extreme events on the Australian environment are mixed: climate change and floods are having a negative impact, but other aspects are good or stable. However, the impacts of all extreme events are getting worse as they become more frequent and severe with climate change. Related to United Nations Sustainable Development Goal targets 1.5, 2.4, 11.5, 13.3 Legend How was this assessment made For more information, go toOutlook and impacts Share on Twitter Share on Facebook Share on Linkedin Share this link Assessment Climate change 2021 Adequate confidence Climate change is increasingly impacting human wellbeing, but currently we can engineer solutions and enhance community resilience to various aspects of climate change. We will increasingly need to see behavioural change rather than technical mitigation. Assessment Cyclones and storms 2021 Adequate confidence Better forecasting means that communities are typically aware of approaching storms in sufficient time to take appropriate action. Loss of life to cyclones has significantly decreased over the past century. Rapid response helps mitigate impacts. Increasing speed of intensification and unpredictable storm behaviour are likely to limit our capacity for planned response. Assessment Floods 2021 Adequate confidence Forecasting means that communities are, with notable exceptions, forewarned of potential flood and inundation events. Increasing frequency of heavy rain may increase unpredictability, limiting our capacity to respond in a timely manner. Assessment Heatwaves 2021 Adequate confidence We are typically able to engineer solutions to manage wellbeing impacts of short-term heatwaves, although marginalised individuals and communities remain at risk. Heatwaves are the single biggest climate-related cause of human mortality in Australia. Longer periods of high temperature are likely to exacerbate impacts. Assessment Bushfires 2021 Adequate confidence Technology to predict bushfire behaviour and enhance infrastructure resilience is improving. Community preference for living in bushland settings is increasing potential exposure. Climate change is likely to increase bushfire risk, but ongoing investment in improving protection of communities could mitigate some risks.
