About Glenbrook's Climate Risk Profile

Glenbrook, nestled in the Blue Mountains, is increasingly vulnerable to climate change impacts. The primary concerns are heightened bushfire risk due to dry vegetation and rising temperatures, and increased flood risk from more intense rainfall events.

The suburb's location near extensive bushland makes it susceptible to bushfires, particularly during the hotter months. Climate change is expected to exacerbate these conditions, leading to more frequent and severe fire seasons.

Additionally, Glenbrook's proximity to Glenbrook Creek and other waterways means it is prone to flooding during heavy rainfall. The intensity of these rainfall events is projected to increase with climate change, further elevating flood risk.

While coastal risks are minimal, the increasing heatwaves pose a threat to vulnerable residents, especially the elderly and those with pre-existing health conditions. Adaptation measures are crucial to protect the community and mitigate the impacts of these climate hazards.
