Learn moreAbout Rossmoyne's Climate Risk Profile
Rossmoyne, a suburb of Perth, Western Australia, is increasingly vulnerable to the impacts of climate change. Rising global temperatures are expected to lead to more frequent and intense heatwaves, posing a significant risk to public health, particularly for vulnerable populations such as the elderly and those with pre-existing medical conditions. The urban heat island effect may further exacerbate these risks.
Located near the Canning River, Rossmoyne is also susceptible to coastal inundation and flooding due to rising sea levels and increased rainfall intensity. These events can damage property, disrupt infrastructure, and pose a threat to human safety. Effective planning and adaptation measures are crucial to mitigate these risks.
While the risk of bushfires in Rossmoyne is relatively low compared to other areas of Western Australia, it is still important to be aware of the potential threat, especially during dry periods. Maintaining vegetation and adhering to fire safety guidelines can help reduce the risk of bushfires.
Addressing climate change in Rossmoyne requires a multi-faceted approach, including reducing greenhouse gas emissions, implementing adaptation measures to protect against the impacts of climate change, and raising awareness among residents about the risks and how to prepare for them. Collaboration between local government, community organizations, and residents is essential to building a climate-resilient community.
