About Dumaresq's Climate Risk Profile

Dumaresq is a suburb in New South Wales that is exposed to a range of climate-related risks. The most significant risks are flooding, bushfires, and heatwaves. Climate change is expected to exacerbate these risks in the coming decades.

Flooding is a concern due to the suburb's proximity to waterways. Intense rainfall events can cause rivers to overflow and lead to flash flooding in low-lying areas. Bushfires are also a threat, particularly during hot, dry periods. The surrounding bushland provides fuel for fires, and strong winds can quickly spread flames.

Heatwaves are becoming more frequent and intense, posing a risk to vulnerable populations, such as the elderly and those with chronic health conditions. Rising temperatures can also strain infrastructure, such as power grids.

While coastal risks are minimal due to Dumaresq's inland location, the community should still be aware of the potential impacts of climate change and take steps to adapt to these changes. This includes investing in flood mitigation measures, managing bushfire risk, and preparing for heatwaves.

Addressing climate change requires a multi-faceted approach, including reducing greenhouse gas emissions and implementing adaptation strategies to protect communities from the impacts of climate change. By working together, residents, businesses, and government can build a more resilient future for Dumaresq.
