Learn moreAbout Molonglo's Climate Risk Profile
Molonglo, located in the Australian Capital Territory, is projected to experience significant impacts from climate change. The primary risks include increased flooding due to more intense rainfall events, and more frequent and severe heatwaves.
The suburb's proximity to the Molonglo River makes it vulnerable to riverine flooding. Urban development can exacerbate this risk by increasing surface runoff. Climate projections indicate that rainfall intensity will increase, leading to a higher risk of flooding in the future.
Heatwaves are also expected to become more common and intense, posing a threat to public health, particularly for vulnerable populations. The urban heat island effect can further amplify these impacts. Residents should take steps to stay cool during heatwaves and ensure they have access to adequate cooling.
While the risk of bushfire is moderate, it is still a concern, especially in areas bordering bushland. Drier conditions and higher temperatures can increase the likelihood of bushfires. Residents should be aware of bushfire risks and have a plan in place in case of a fire.
Overall, Molonglo needs to adapt to the changing climate by implementing measures to reduce flood risk, mitigate the impacts of heatwaves, and manage bushfire risk. These measures will help to protect the community and ensure its long-term resilience.
