Climate Hazard Breakdown for Mount Marsh

Flood

Mount Marsh faces a moderate risk of flooding, primarily from heavy rainfall events and potential riverine flooding. The risk is influenced by the local topography and drainage systems.

Key drivers:

  • ·Increased rainfall intensity
  • ·Urban development

Bushfire

The bushfire risk in Mount Marsh is relatively high due to the proximity of bushland areas. Hot, dry conditions during the fire season can exacerbate the risk.

Key drivers:

  • ·Dry vegetation
  • ·High temperatures

Heat

Mount Marsh experiences moderate heat risk, with increasing average temperatures and more frequent heatwave events projected in the future.

Key drivers:

  • ·Climate change
  • ·Urban heat island effect

Coastal

As an inland suburb, Mount Marsh has a very low risk associated with coastal hazards.

What This Means for Property Owners

Insurance Outlook

Insurance premiums are likely to increase due to the elevated flood and bushfire risks.

Price Impact

Property values may be negatively impacted by increasing climate risks.

Buyer Checklist

  • 1.Check flood maps and potential flood risks.
  • 2.Assess bushfire risk and implement mitigation measures.
  • 3.Consider the impact of heatwaves on property comfort and energy costs.
  • 4.Review insurance options and potential premium increases.

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 Mount Marsh's Climate Risk Profile

Mount Marsh, NSW, is a suburb that is increasingly vulnerable to the impacts of climate change. The primary concerns are related to 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 increased rainfall intensity and potential riverine flooding. The local topography and drainage systems play a crucial role in managing this risk. Bushfire risk is elevated due to the proximity of bushland areas, with hot, dry conditions during the fire season increasing the likelihood of fires.

Heatwaves are becoming more frequent and intense, posing a threat to vulnerable populations. The urban heat island effect can further amplify these risks. While coastal risks are minimal due to its inland location, the suburb is still indirectly affected by broader climate change impacts.

Addressing these challenges requires a combination of mitigation and adaptation strategies. Mitigation efforts focus on reducing greenhouse gas emissions, while adaptation strategies aim to build resilience to the impacts of climate change. These strategies include improving infrastructure, implementing early warning systems, and promoting community awareness.

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