Climate Hazard Breakdown for Adelaide CBD

increasing

Flood

65/100

The Adelaide CBD area faces a moderate risk of flooding, primarily from heavy rainfall events and potential stormwater runoff. The risk is exacerbated by the urban environment and limited permeable surfaces.

Key drivers:

  • ·Increased rainfall intensity
  • ·Urbanisation
stable

Bushfire

20/100

Bushfire risk in Adelaide CBD is relatively low due to its highly urbanised nature and lack of significant vegetation. However, ember attack from distant fires remains a potential concern.

Key drivers:

  • ·Urban density
  • ·Limited vegetation
increasing

Heat

70/100

Adelaide CBD experiences significant heat risk, particularly during summer months. Urban heat island effect amplifies temperatures, posing health risks to vulnerable populations.

Key drivers:

  • ·Urban heat island effect
  • ·Increased frequency of heatwaves
increasing

Coastal

10/100

Coastal risk in Adelaide CBD is minimal due to its distance from the immediate coastline. Sea level rise and storm surges pose a very low direct threat.

About Adelaide CBD's Climate Risk Profile

Adelaide CBD, as a highly urbanised area, is particularly vulnerable to the impacts of climate change, especially increased heatwaves and flooding. The urban heat island effect intensifies summer temperatures, posing significant health risks to residents, particularly the elderly and those with pre-existing conditions.

Flooding is another key concern, with heavy rainfall events potentially overwhelming stormwater systems. The lack of permeable surfaces in the CBD contributes to increased runoff and flood risk. Climate change projections indicate an increase in the intensity and frequency of heavy rainfall events, further exacerbating this risk.

While bushfire risk is relatively low due to the urban nature of the CBD, ember attack from distant fires remains a potential threat. Coastal risks are also low due to the distance from the immediate coastline, but sea level rise could indirectly impact infrastructure and services.

Addressing these climate risks requires a multi-faceted approach, including increasing green spaces to mitigate the urban heat island effect, upgrading stormwater infrastructure to manage increased rainfall, and implementing heatwave early warning systems. Community awareness and preparedness are also crucial for building resilience to climate change impacts.
