Learn moreAbout Sorell's Climate Risk Profile
Sorell, Tasmania, is a region that is increasingly vulnerable to the impacts of climate change. The primary risks include flooding due to increased rainfall and sea level rise, bushfires exacerbated by hotter and drier conditions, more frequent and intense heatwaves, and coastal hazards such as erosion and storm surges.
The risk of flooding is a significant concern for Sorell, given its proximity to waterways and low-lying coastal areas. Climate change is expected to increase rainfall intensity, leading to more frequent and severe flooding events. Sea level rise will further exacerbate this risk, particularly in coastal areas.
Bushfire risk is also projected to increase in Sorell due to hotter and drier conditions. Changes in temperature and rainfall patterns could lead to longer bushfire seasons and more intense fires. This poses a threat to properties and infrastructure located near bushland.
Heatwaves are expected to become more frequent and intense in Sorell as a result of climate change. This could have significant impacts on human health, particularly for vulnerable populations such as the elderly and those with chronic health conditions.
Coastal hazards, such as erosion and storm surges, are also a concern for Sorell. Sea level rise is expected to increase the frequency and severity of these events, posing a threat to coastal properties and infrastructure.
