Learn moreAbout Glenorchy's Climate Risk Profile
Glenorchy, Tasmania, is a suburb that will be increasingly affected by climate change. The primary risks include flooding from the Derwent River and local creeks, bushfires in areas bordering bushland, more frequent and intense heatwaves, and coastal inundation due to sea level rise.
Increased rainfall intensity is expected to worsen flood risks, while drier conditions and higher temperatures will elevate bushfire risks. Heatwaves will pose a threat to vulnerable populations, and sea level rise could impact low-lying areas and infrastructure.
These risks are projected to increase significantly by 2030 and 2050 under high emissions scenarios. It is crucial for residents and local authorities to take proactive measures to adapt to these changes.
Adaptation strategies include improving flood defenses, managing vegetation to reduce bushfire risks, implementing heatwave early warning systems, and planning for coastal inundation. Individual actions, such as preparing emergency kits and staying informed about weather warnings, are also essential.
