Learn moreAbout Carrum Downs's Climate Risk Profile
Carrum Downs, located in the southeastern suburbs of Melbourne, is increasingly vulnerable to the impacts of climate change. The suburb's flat terrain and proximity to Port Phillip Bay make it susceptible to flooding from heavy rainfall and rising sea levels. Heatwaves are also becoming more frequent and intense, posing a significant risk to vulnerable populations.
The primary climate risks for Carrum Downs include flooding, heatwaves, and coastal inundation. Increased rainfall intensity and urban development contribute to the flood risk, while rising global temperatures exacerbate heatwave conditions. Sea level rise and storm surges threaten low-lying coastal areas.
Climate projections indicate that these risks will intensify in the coming decades. By 2030 and 2050, Carrum Downs is expected to experience more frequent and severe extreme weather events, including floods, heatwaves, and coastal storms. These changes could have significant impacts on property values, infrastructure, and community well-being.
Adapting to climate change is crucial for Carrum Downs. This includes investing in improved drainage infrastructure, implementing heatwave management plans, and protecting coastal areas from erosion and inundation. Community awareness and preparedness are also essential to minimize the impacts of extreme weather events.
