Learn moreAbout chisholm's Climate Risk Profile
Chisholm, located in the Australian Capital Territory, is subject to a range of climate-related risks. The suburb's proximity to bushland increases its vulnerability to bushfires, especially during the hot, dry summer months. Changes in rainfall patterns and increased storm intensity also contribute to flood risk, particularly in low-lying areas.
Rising average temperatures and more frequent heatwaves pose a significant threat to vulnerable populations, including the elderly and those with pre-existing health conditions. The urban environment can amplify these effects, creating urban heat islands that exacerbate heat stress.
Climate change projections indicate that these risks are likely to intensify in the coming decades. Increased rainfall intensity could lead to more frequent and severe flooding events, while hotter and drier conditions could increase the risk and severity of bushfires. Adapting to these changes will require a combination of individual preparedness, community resilience, and government action.
Mitigation efforts, such as reducing greenhouse gas emissions, are also crucial to slowing the pace of climate change and reducing the long-term risks to Chisholm. Residents can contribute by adopting sustainable practices, such as reducing energy consumption, using public transport, and supporting policies that promote a low-carbon economy.
