Learn moreAbout Green Hills's Climate Risk Profile
Green Hills is a suburb in New South Wales that is increasingly vulnerable to the impacts of climate change. The primary risks include flooding from heavy rainfall, more frequent and intense heatwaves, and a moderate risk of bushfires.
The risk of flooding is driven by increased rainfall intensity and inadequate drainage infrastructure. Climate change is expected to exacerbate these issues, leading to more frequent and severe flooding events. Residents should be aware of flood risks and take steps to protect their properties.
Heatwaves are becoming more common and intense, posing a significant threat to vulnerable populations. The urban heat island effect can further amplify temperatures in built-up areas. It is important to stay hydrated, seek shelter in cool places, and check on elderly or vulnerable neighbors during heatwaves.
The bushfire risk is moderate due to the presence of surrounding bushland. Hot, dry conditions during summer increase the likelihood of bushfires. Residents should maintain their properties to reduce fire hazards and be prepared to evacuate if necessary.
While coastal risks are low due to the suburb's inland location, the broader impacts of climate change, such as disruptions to supply chains and infrastructure, can still affect Green Hills.
