Victoria's climate is already changing and is likely to change further in the future, posing significant risks to the state.
Many types of climate-related extreme events are expected to increase in frequency and intensity in the future. The heatwaves, drought and bushfires of the past decade provide Victorians with a window into that future.
The number of hot days has increased over the last few decades and is expected to continue increasing into the future. Critical infrastructure, such as roads, railways and power lines, is vulnerable to prolonged exposure to high temperatures. Conditions for large and intense bushfires are likely to become more common in the future. The number of ‘very high’ and ‘extreme’ fire danger days could increase significantly over the next few decades.
Over the last 40 years much of eastern and southern Australia has become drier, with Victoria experiencing a 10-20% reduction in autumn and winter rain over the last 20 years.
