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 Old Mill

Flood

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

Bushfire

The suburb has a moderate bushfire risk due to surrounding vegetation. Hotter, drier conditions are expected to increase the frequency and intensity of bushfires.

Key drivers:

  • ·Increased temperatures
  • ·Drier conditions

Heat

The suburb is likely to experience more frequent and intense heatwaves. This poses a risk to vulnerable populations, such as the elderly and those with chronic health conditions.

Key drivers:

  • ·Increased temperatures
  • ·Urban heat island effect

Coastal

Coastal risk is low due to the suburb's distance from the coast. Sea level rise is not expected to have a significant impact.

Key drivers:

  • ·Sea level rise
  • ·Storm surge

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 Old Mill's Climate Risk Profile

Old Mill is a suburb in New South Wales that is increasingly vulnerable to the impacts of climate change. The primary risks include flooding, bushfires, and heatwaves. Changes in rainfall patterns and rising temperatures are expected to exacerbate these risks in the coming decades.

Flooding is a significant concern due to the suburb's proximity to waterways. Increased rainfall intensity and potential sea level rise could lead to more frequent and severe flooding events. Residents should be aware of local flood risks and take appropriate precautions.

Bushfire risk is also a factor, particularly during the dry season. Hotter, drier conditions increase the likelihood of bushfires, which can pose a threat to property and human life. It is important for residents to maintain their properties and be prepared for bushfire emergencies.

Heatwaves are becoming more frequent and intense, posing a risk to vulnerable populations. The elderly, children, and those with chronic health conditions are particularly susceptible to heat-related illnesses. Residents should take steps to stay cool during heatwaves and check on their neighbors.

Overall, Old Mill faces a range of climate-related challenges. By understanding these risks and taking appropriate action, residents can help to protect themselves and their community.
