increasing

Flood

85/100

Collarenebri faces a high risk of flooding due to its proximity to the Barwon River and flat terrain. Climate change is expected to increase the frequency and intensity of heavy rainfall events, exacerbating flood risk.

Key drivers:

  • ·Increased rainfall intensity
  • ·Riverine flooding
increasing

Bushfire

60/100

The area surrounding Collarenebri has a moderate bushfire risk due to the presence of grasslands and sparse woodland. Hot, dry conditions during summer increase the likelihood of bushfires.

Key drivers:

  • ·Increased temperatures
  • ·Drier conditions
increasing

Heat

80/100

Collarenebri experiences very hot summers, and climate change is projected to increase the frequency and intensity of heatwaves, posing a significant risk to vulnerable populations.

About Collarenebri's Climate Risk Profile

Collarenebri, located in inland New South Wales, is particularly vulnerable to the impacts of climate change. The primary risks include increased flooding due to its proximity to the Barwon River, more frequent and intense heatwaves, and a moderate risk of bushfires.

The risk of flooding is expected to increase as climate change leads to more intense rainfall events. The flat terrain around Collarenebri exacerbates this risk, as water can spread quickly and inundate properties. Residents should be aware of flood warnings and have a plan in place to evacuate if necessary.

Heatwaves are already a common occurrence in Collarenebri, and climate change is projected to make them even more frequent and severe. This poses a significant risk to vulnerable populations, such as the elderly and those with chronic health conditions. It is important to stay hydrated, seek shelter in air-conditioned environments, and check on neighbors during heatwaves.

While not as significant as flooding and heatwaves, bushfires also pose a risk to Collarenebri. The surrounding grasslands and sparse woodland can provide fuel for fires, particularly during hot, dry conditions. Residents should maintain their properties to reduce the risk of fire spread and be aware of bushfire warnings.

Adapting to climate change will require a concerted effort from individuals, businesses, and the local government. This includes investing in flood mitigation measures, improving building design to withstand extreme heat, and implementing strategies to reduce greenhouse gas emissions.
