About Thornlands's Climate Risk Profile

Thornlands, located in the Redland City region of Queensland, is increasingly vulnerable to the impacts of climate change. The suburb's coastal location and proximity to waterways make it susceptible to flooding and coastal erosion. Rising temperatures are also contributing to more frequent and intense heatwaves, posing risks to public health and infrastructure.

Flooding is a significant concern, with potential for both riverine and stormwater flooding during heavy rainfall events. Sea level rise is exacerbating coastal erosion and increasing the risk of inundation in low-lying areas. Bushfire risk is moderate, requiring ongoing vigilance and mitigation efforts.

The local council is implementing various strategies to address climate change, including improving stormwater drainage, protecting coastal ecosystems, and promoting energy efficiency. Residents can also take individual actions to reduce their vulnerability, such as installing rainwater tanks, improving home insulation, and developing emergency plans.

Climate projections indicate that these risks will continue to intensify in the coming decades. It is crucial for the community to work together to adapt to these changes and build a more resilient future. This includes investing in infrastructure upgrades, implementing stricter building codes, and raising awareness about climate risks.
