About Ascot's Climate Risk Profile

Ascot, a suburb of Brisbane, Queensland, is increasingly exposed to climate-related risks. The primary concerns are flooding, heatwaves, and coastal hazards. Rising global temperatures and changing weather patterns are expected to exacerbate these risks in the coming decades.

Flooding is a significant threat due to Ascot's proximity to the Brisbane River and low-lying areas. Increased rainfall intensity and potential sea level rise could lead to more frequent and severe flooding events. Properties in flood-prone zones are particularly vulnerable.

Heatwaves are another major concern, with rising temperatures posing health risks to residents, especially the elderly and vulnerable. The urban heat island effect further amplifies the impact of heatwaves in Ascot. Reduced green cover and increased paved surfaces contribute to this effect.

Coastal hazards, including sea level rise and storm surge, also pose a threat to Ascot. Low-lying areas near the Brisbane River are susceptible to inundation during extreme weather events. Erosion and coastal degradation could further exacerbate these risks.

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 cover, and implementing heatwave early warning systems, are also essential to protect the community.
