Climate Hazard Breakdown for Idalia

Flood

Idalia faces a moderate risk of flooding due to its proximity to the Ross River and other waterways. Climate change is expected to increase rainfall intensity, potentially leading to more frequent and severe flood events.

Key drivers:

  • ·Increased rainfall intensity
  • ·Proximity to waterways

Bushfire

The risk of bushfire in Idalia is moderate, with some areas bordering bushland. Hotter and drier conditions due to climate change may increase the frequency and intensity of bushfires.

Key drivers:

  • ·Increased temperatures
  • ·Drier conditions

Heat

Idalia experiences high temperatures, particularly during the summer months. Climate change is projected to increase the frequency and intensity of heatwaves, posing a risk to vulnerable populations.

Key drivers:

  • ·Increased temperatures
  • ·Urban heat island effect

Coastal

Idalia is located inland and has a low risk of coastal hazards such as sea level rise and coastal erosion.

Key drivers:

  • ·Distance from the coast

What This Means for Property Owners

Insurance Outlook

Insurance premiums may increase in the future due to increased flood and heatwave risks.

Price Impact

Properties in flood-prone areas may experience a decrease in value.

Buyer Checklist

  • 1.Check flood maps and insurance costs.
  • 2.Assess the property's vulnerability to heatwaves.
  • 3.Consider the long-term impacts of climate change on property values.

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 Idalia's Climate Risk Profile

Idalia, located in the Townsville region of Queensland, is increasingly vulnerable to the impacts of climate change. The primary risks include flooding due to its proximity to the Ross River, and heatwaves during the summer months. These risks are projected to intensify in the coming decades, potentially affecting property values, infrastructure, and the health of residents.

Flooding is a significant concern for Idalia. Increased rainfall intensity, driven by climate change, could lead to more frequent and severe flood events. This poses a threat to homes, businesses, and critical infrastructure. Residents should be aware of flood risks and take appropriate precautions.

Heatwaves are another major concern. Townsville already experiences high temperatures, and climate change is expected to increase the frequency and intensity of heatwaves. This can lead to heat stress, particularly for vulnerable populations such as the elderly and those with chronic health conditions.

While Idalia is located inland, the potential for indirect impacts from coastal hazards, such as disruptions to supply chains and infrastructure, should also be considered. It is important for residents and businesses to stay informed about climate risks and take steps to adapt to the changing climate.

Addressing these climate risks requires a coordinated effort from all levels of government, as well as the community. This includes investing in infrastructure improvements, implementing adaptation measures, and reducing greenhouse gas emissions.

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