About Greengrove's Climate Risk Profile

Greengrove, located in Western Sydney, is projected to experience significant impacts from climate change. The primary risks are increased flooding due to more intense rainfall events, and more frequent and severe heatwaves. The suburb also faces a moderate risk of bushfires due to surrounding bushland.

Flooding is a major concern, with potential for increased inundation of low-lying areas. Climate change models predict more intense rainfall, which could overwhelm existing drainage infrastructure. Residents should be aware of flood risks and have evacuation plans in place.

Heatwaves are also expected to become more frequent and severe, posing a significant risk to vulnerable populations, such as the elderly and those with chronic health conditions. Urban heat island effects can exacerbate these risks.

Bushfire risk is present due to the proximity of bushland areas. Hotter, drier conditions increase the likelihood of bushfires, and residents should be prepared to take action during bushfire season.

While Greengrove is not directly exposed to coastal risks, the broader impacts of climate change, such as disruptions to supply chains and increased insurance costs, could still affect the suburb. Adaptation measures are needed to mitigate these risks and build resilience.
