About calwell's Climate Risk Profile

Calwell, located in the Tuggeranong Valley, is projected to experience more frequent and intense heatwaves, increasing the risk of heatstroke and other heat-related illnesses. The suburb's proximity to grasslands and bushland also makes it vulnerable to bushfires, especially during hot, dry summers. Changes in rainfall patterns could lead to more intense storms and flash flooding, particularly in areas with poor drainage.

The ACT government is working to mitigate these risks through various initiatives, including urban planning strategies to reduce the urban heat island effect, bushfire management programs, and upgrades to stormwater infrastructure. However, individual preparedness is also crucial. Residents should develop emergency plans, maintain their properties to reduce fire hazards, and stay informed about weather warnings.

Climate change projections indicate that these risks will continue to increase in the coming decades. By 2050, Calwell is likely to experience significantly more days above 35°C, and the risk of severe bushfires will be higher. Adapting to these changes will require a concerted effort from individuals, communities, and government agencies.

Homeowners should consider measures such as installing energy-efficient air conditioning, improving insulation, and creating defensible space around their properties. Community-level initiatives, such as neighborhood emergency response teams, can also play a vital role in building resilience. Staying informed about climate change and its potential impacts is the first step towards taking effective action.
