About Greenleigh's Climate Risk Profile

Greenleigh, NSW, is a suburb that is increasingly vulnerable to the impacts of climate change. The primary risks include flooding from increased rainfall intensity, bushfires due to hotter and drier conditions, and heatwaves that can impact vulnerable populations.

The risk of flooding is driven by more intense rainfall events and potential overflow from local waterways. Climate change is expected to exacerbate these conditions, leading to more frequent and severe flooding.

Bushfire risk is significant due to the suburb's proximity to bushland areas. Hotter, drier conditions and strong winds increase the likelihood of bushfires. Climate change is projected to worsen bushfire seasons, posing a greater threat to properties and lives.

Heatwaves are becoming more frequent and intense, posing a risk to the elderly, children, and those with pre-existing health conditions. The urban heat island effect can further amplify these risks.

While coastal risks are low due to Greenleigh's inland location, the suburb is still indirectly affected by broader climate change impacts. Residents should take proactive measures to adapt to these changing conditions and mitigate potential risks.
