About Cook's Climate Risk Profile

Cook, located in the Australian Capital Territory, is projected to experience more frequent and intense heatwaves, increasing the risk of heat stress, particularly for vulnerable populations. Changes in rainfall patterns are expected to increase the risk of flooding, especially during intense rainfall events.

The suburb's proximity to bushland areas also contributes to a moderate bushfire risk. Residents should maintain their properties to reduce fuel loads and stay informed about bushfire warnings.

Climate change is expected to exacerbate these risks in the coming decades. Projections indicate a continued increase in average temperatures and more extreme weather events. Adaptation measures are crucial to protect the community and infrastructure.

Homeowners should review their insurance policies and consider implementing property-level adaptations to mitigate climate risks. Staying informed about local emergency plans and heeding warnings from authorities is essential for ensuring safety during extreme weather events.
