Climate Hazard Breakdown for Greenwich Park

increasing

Flood

60/100

The area faces a moderate risk of flooding due to its proximity to waterways and low-lying areas. Climate change is expected to increase rainfall intensity, exacerbating flood risk.

Key drivers:

  • ·Increased rainfall intensity
  • ·Sea level rise
increasing

Bushfire

40/100

Greenwich Park has a relatively low bushfire risk due to the distance from dense bushland. However, increased temperatures and drier conditions could elevate the risk.

Key drivers:

  • ·Increased temperatures
  • ·Drier conditions
increasing

Heat

70/100

The suburb is likely to experience more frequent and intense heatwaves. This poses a risk to vulnerable populations, especially during summer.

Key drivers:

  • ·Rising average temperatures
  • ·Urban heat island effect
increasing

Coastal

50/100

While not directly on the coast, Greenwich Park may experience indirect impacts from coastal hazards such as storm surges and sea level rise affecting nearby areas.

About Greenwich Park's Climate Risk Profile

Greenwich Park, NSW, is projected to experience a range of climate change impacts over the coming decades. Rising temperatures will lead to more frequent and intense heatwaves, posing health risks to residents, particularly the elderly and those with pre-existing conditions.

Changes in rainfall patterns are expected to increase the risk of flooding. More intense rainfall events could overwhelm existing drainage infrastructure, leading to property damage and disruption to daily life. The suburb's proximity to waterways further exacerbates this risk.

Bushfire risk is relatively lower compared to other areas in NSW, but hotter and drier conditions could still increase the potential for bushfires, especially during prolonged dry spells. Residents should remain vigilant and prepared for bushfire season.

Indirect impacts from coastal hazards, such as storm surges and sea level rise, could also affect Greenwich Park. While not directly on the coast, the suburb may experience disruptions to transportation and supply chains due to coastal erosion and inundation in nearby areas.
