Learn moreAbout holder's Climate Risk Profile
Holder, located in the Weston Creek district of Canberra, is increasingly vulnerable to the impacts of climate change. The suburb's proximity to bushland elevates the risk of bushfires, particularly during dry and windy conditions. Climate change is expected to exacerbate these conditions, leading to more frequent and intense bushfire seasons.
Heatwaves are another significant concern for Holder. As temperatures rise, the risk of heat-related illnesses increases, especially for vulnerable populations such as the elderly and those with chronic health conditions. The urban heat island effect can further amplify temperatures in built-up areas.
Flooding is a moderate risk for Holder, with potential for localised flooding during periods of heavy rainfall. Adequate drainage infrastructure is crucial to mitigate this risk.
While coastal hazards are not a direct threat to Holder due to its inland location, the broader impacts of climate change, such as disruptions to supply chains and increased migration, could indirectly affect the suburb. Residents should stay informed about climate risks and take steps to prepare for extreme weather events.
