Learn moreAbout Kogarah's Climate Risk Profile
Kogarah, located in the southern suburbs of Sydney, is exposed to several climate-related risks. The suburb's proximity to the Georges River makes it vulnerable to flooding, particularly during periods of heavy rainfall. Climate change is expected to increase the intensity and frequency of extreme rainfall events, further exacerbating the flood risk.
Heatwaves are another significant concern for Kogarah residents. The urban environment contributes to the urban heat island effect, resulting in higher temperatures compared to surrounding areas. As global temperatures continue to rise, heatwaves are projected to become more frequent and severe, posing a threat to public health.
Coastal hazards, such as sea level rise and storm surges, also pose a risk to Kogarah. The Georges River estuary is susceptible to inundation during high tides and storm events. Rising sea levels will increase the frequency and extent of coastal flooding, potentially impacting properties and infrastructure.
Addressing these climate risks requires a combination of mitigation and adaptation strategies. Reducing greenhouse gas emissions is crucial to slowing down the rate of climate change. Local adaptation measures, such as improving drainage infrastructure, increasing green space, and implementing coastal protection measures, can help to reduce the impacts of climate change on Kogarah.
