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 Twelve Mile Creek

Flood

The area is susceptible to flooding from heavy rainfall and nearby waterways. Climate change is expected to increase the intensity of rainfall events.

Key drivers:

  • ·Increased rainfall intensity
  • ·Proximity to waterways

Bushfire

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

Key drivers:

  • ·Increased temperatures
  • ·Drier conditions

Heat

The area is likely to experience more frequent and intense heatwaves. This poses a risk to vulnerable populations.

Key drivers:

  • ·Rising average temperatures
  • ·Increased frequency of heatwaves

Coastal

Twelve Mile Creek is not located near the coast, therefore the risk of coastal hazards is very low.

Key drivers:

  • ·Distance from coast

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 Twelve Mile Creek's Climate Risk Profile

Twelve Mile Creek is a rural locality in New South Wales that is increasingly vulnerable to the impacts of climate change. The primary concerns for the area are flooding, heatwaves, and bushfires. 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 potential for heavy rainfall events and the presence of nearby waterways. Climate change is projected to increase the intensity of rainfall, leading to more frequent and severe flooding. This can damage property, disrupt infrastructure, and pose a threat to human safety.

Heatwaves are also a growing concern, with rising average temperatures and more frequent extreme heat events. This can lead to heat stress, particularly for vulnerable populations such as the elderly and those with chronic health conditions. The urban heat island effect may further exacerbate the impacts of heatwaves in built-up areas.

Bushfire risk is moderate, with surrounding vegetation providing fuel for potential fires. Hotter and drier conditions are expected to increase the frequency and intensity of bushfires, posing a threat to property and human life. While Twelve Mile Creek is not located near the coast, coastal hazards are not a significant concern for this inland locality.

Addressing these climate risks will require a combination of adaptation and mitigation measures. This includes investing in flood protection infrastructure, implementing heatwave early warning systems, and managing vegetation to reduce bushfire risk. Reducing greenhouse gas emissions is also essential to limit the long-term impacts of climate change.

Suburb pages describe the local picture. The address-level assessment, with its data sources and its dollar projections, is in the ClimateNest report.
