Overall Risk Score

Address-level

Hazard Breakdown

Flood, bushfire, heat, coastal and storm exposure are all assessed in this area. The score that matters is the property's own: a ClimateNest report scores the address across eight hazards, with insurance and value projections to 2050.

Climate Hazard Breakdown for Greenwich

Flood

Greenwich has a moderate risk of flooding due to its proximity to the Lane Cove River and Sydney Harbour. Several properties are located in low-lying areas that are susceptible to inundation during heavy rainfall events.

Key drivers:

  • ·Increased rainfall intensity
  • ·Sea level rise

Bushfire

Greenwich has a relatively low risk of bushfire due to its location and urban density. However, some properties bordering parks and reserves may face a slightly elevated risk.

Key drivers:

  • ·Proximity to bushland
  • ·Dry vegetation

Heat

Greenwich experiences moderate heat risk, with increasing average temperatures and more frequent heatwaves projected. This can impact vulnerable populations and increase energy demand for cooling.

Key drivers:

  • ·Rising global temperatures
  • ·Urban heat island effect

Coastal

Greenwich faces a moderate risk from coastal hazards due to its location on Sydney Harbour. Sea level rise and storm surges could lead to increased erosion and inundation of waterfront properties.

Key drivers:

  • ·Sea level rise
  • ·Increased storm intensity

How the region's climate is projected to change

Regional projections, not a forecast for this street. Figures are from the WA Department of Water and Environmental Regulation's climate projections for the South Western Flatlands region, which draws on CSIRO and Bureau of Meteorology modelling.

Temperature

+0.5 to 1.1°C by 2030

Above the 1986–2005 climate, on all emissions scenarios. By 2090, 1.2 to 2.0°C under intermediate emissions or 2.6 to 4.0°C under high emissions.

Rainfall

Winter rain down up to 15% by 2030

The South West has been drying since 1970, and the decline has been larger than anywhere else in Australia. Heavy rainfall events are projected to become more intense even as totals fall.

Fire weather

Harsher, magnitude uncertain

High confidence that fire weather becomes harsher, low confidence in the size of the change, because it depends heavily on summer rainfall.

Sea level

+0.12 m by 2030

At the Fremantle gauge, range 0.07 to 0.16 m. Very high confidence that sea levels continue to rise through the century.

About Greenwich's Climate Risk Profile

Greenwich, located on the lower North Shore of Sydney, faces several climate change-related challenges. Its proximity to the Lane Cove River and Sydney Harbour makes it vulnerable to flooding from heavy rainfall and rising sea levels. Climate change is expected to increase the intensity of rainfall events, exacerbating flood risk in low-lying areas.

Bushfire risk is relatively low in Greenwich due to its urban environment, but properties near parks and reserves should remain vigilant. Rising temperatures and prolonged dry periods could increase the risk of bushfires in surrounding areas, potentially impacting the suburb.

Heatwaves are becoming more frequent and intense in Sydney, posing a health risk to vulnerable populations in Greenwich. The urban heat island effect can further amplify temperatures in built-up areas. Residents should take precautions during heatwaves, such as staying hydrated and seeking air-conditioned environments.

Sea level rise is a significant concern for Greenwich, with potential impacts on waterfront properties and infrastructure. Coastal erosion and inundation could become more frequent and severe, requiring adaptation measures to protect coastal assets. Planning for future climate scenarios is crucial to ensure the long-term resilience of Greenwich.
