Climate Hazard Breakdown for Mullion Creek

Flood

Mullion Creek faces a moderate risk of flooding, primarily from heavy rainfall events and local creek overflows. The risk is expected to increase due to climate change.

Key drivers:

  • ·Increased rainfall intensity
  • ·Local creek overflow

Bushfire

The area around Mullion Creek is prone to bushfires, particularly during dry periods and heatwaves. The risk is exacerbated by surrounding bushland and potential for strong winds.

Key drivers:

  • ·Dry vegetation
  • ·High temperatures

Heat

Mullion Creek is likely to experience more frequent and intense heatwaves in the future. This poses a risk to vulnerable populations and infrastructure.

Key drivers:

  • ·Rising global temperatures
  • ·Urban heat island effect

Coastal

As Mullion Creek is not located near the coast, the risk of coastal hazards such as sea level rise and coastal erosion 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 Mullion Creek's Climate Risk Profile

Mullion Creek, located in New South Wales, is exposed to a range of climate-related risks. The primary concerns are bushfires, flooding, and heatwaves, which are projected to become more frequent and intense due to climate change.

Bushfire risk is significant due to the surrounding bushland. Hot, dry conditions combined with strong winds can create ideal conditions for bushfires to spread rapidly, threatening homes and livelihoods. Residents should be prepared for potential evacuations and property protection measures.

Flooding is another concern, particularly during periods of heavy rainfall. Local creeks and waterways can overflow, inundating low-lying areas and disrupting transportation. Climate change is expected to increase rainfall intensity, exacerbating flood risk.

Heatwaves are also becoming more frequent and intense, posing a risk to vulnerable populations such as the elderly and those with chronic health conditions. Extreme heat can also strain infrastructure, such as power grids and transportation systems.

While coastal risks are minimal due to the suburb's inland location, the community should still be aware of the broader impacts of climate change and take steps to adapt to a changing environment.

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