About Rennie's Climate Risk Profile

Rennie, NSW, is exposed to several climate-related risks that are projected to intensify in the coming decades. The most significant threats include increased flooding due to more intense rainfall events and rising temperatures leading to more frequent and severe heatwaves.

The risk of flooding is driven by the suburb's proximity to waterways and the potential for heavy rainfall. Climate change models predict an increase in extreme precipitation events, which could overwhelm existing drainage infrastructure and lead to more widespread flooding.

Heatwaves are also a growing concern, with average temperatures expected to rise. This poses a particular risk to vulnerable populations, such as the elderly and those with pre-existing health conditions. The urban heat island effect could further exacerbate the impact of heatwaves in built-up areas.

While Rennie is somewhat inland, bushfire risk remains a consideration, especially during dry periods. Changes in temperature and rainfall patterns could lead to drier vegetation and a longer fire season.

Addressing these climate risks will require a combination of adaptation and mitigation strategies, including investments in flood control infrastructure, heatwave preparedness plans, and bushfire prevention measures.
