Climate Hazard Breakdown for Charmhaven

Flood

Charmhaven faces a moderate risk of flooding due to its proximity to Lake Munmorah and low-lying areas. Intense rainfall events can lead to stormwater runoff and riverine flooding.

Key drivers:

  • ·Increased rainfall intensity
  • ·Sea level rise

Bushfire

The risk of bushfire in Charmhaven is moderate, with some areas bordering bushland. Hot, dry conditions and strong winds can increase the likelihood of fire.

Key drivers:

  • ·Increased temperatures
  • ·Drier conditions

Heat

Charmhaven is likely to experience more frequent and intense heatwaves. High temperatures can pose a risk to vulnerable populations.

Key drivers:

  • ·Increased greenhouse gas emissions
  • ·Urban heat island effect

Coastal

Charmhaven faces a moderate risk from coastal hazards due to its proximity to the coast and Lake Munmorah. Sea level rise and storm surges can lead to coastal erosion and inundation.

Key drivers:

  • ·Sea level rise
  • ·Increased storm intensity

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 Charmhaven's Climate Risk Profile

Charmhaven, located on the Central Coast of New South Wales, is increasingly vulnerable to the impacts of climate change. The suburb's proximity to Lake Munmorah and the coast makes it susceptible to flooding and coastal erosion. Rising temperatures and more frequent heatwaves pose a significant risk to public health, especially for vulnerable populations.

Flooding is a major concern for Charmhaven. Intense rainfall events can overwhelm stormwater drainage systems and cause widespread inundation. Sea level rise is exacerbating the risk of coastal flooding, particularly during storm surges. The local council is working to improve drainage infrastructure and implement coastal protection measures, but further action is needed to mitigate the growing threat.

Bushfire risk is also a factor, with some areas of Charmhaven bordering bushland. Hot, dry conditions and strong winds can create a high fire danger. Residents should be aware of bushfire safety precautions and have a plan in place in case of an emergency.

Heatwaves are becoming more frequent and intense in Charmhaven. High temperatures can lead to heatstroke and other health problems. It is important to stay hydrated, seek shade, and avoid strenuous activity during heatwaves. The local council is working to provide cooling centers and other resources to help residents cope with the heat.

Adapting to climate change will require a concerted effort from residents, businesses, and the local council. By taking steps to reduce greenhouse gas emissions and prepare for the impacts of climate change, Charmhaven can build a more resilient future.
