Global warming and climate change will pose a significant challenge to all levels of government and the City of Casey is working with other councils in the region through the South East Councils Climate Change Alliance (SECCCA) to understand the impacts of global warming and climate change, and prepare for them.
The impacts of climate change are as follows:
Average temperatures are expected to increase, as is the number of extreme heat days and heat waves. Higher summer temperatures could impact on cooling systems, the longevity of buildings and infrastructure. The health of the community is also a consideration, particularly those vulnerable to the effects of heat such as children, the elderly, and the sick and infirm.
Rising sea levels
Sea level has already risen and this is projected to continue. The Victorian Coastal Strategy requires Council to plan for an 80cm (0.8 metre) increase in the average sea level by 2100. The effects of sea level rise will be most pronounced during extreme tides and storm events when the effects of wind amplify the height and force of waves.
More extreme rainfall and droughts
Casey, like most of south-east Australia, is expected to experience significant reductions in average rainfall resulting in decreased flows in rivers and streams. Climate models also project an increase in the frequency and severity of drought periods.
Fire risk weather
The combination of higher temperatures and increased evaporation, as well as reductions in annual rainfall and increase in drought means Casey is expected to be hotter and the landscape drier. This means the overall risk of bushfire is expected to increase.
Storms and floods
Although the period between rains is predicted to extend, when it does rain, storm events are likely to be more extreme. Increased rainfall intensity may cause flash flooding and the strength and frequency of wind is also expected to increase.
Western Port Local Coastal Hazards Assessment
Casey participated in this project to examine coastal processes and hazards that might result from climate change impacts. The reports from the project are available at the website of project partner the South East Councils Climate Change Alliance. For more information and for the reports visit the Western Port Local Coastal Hazard Assessment webpage on the SECCCA website.
More information about the projected impacts of climate change can be found in the Climate Change booklet (1mb).
