Southern Cross Station, Melbourne MELBOURNE’S Greater Melbourne climate projections CLIMATE JOURNEY Overview Over the past summer, people across Greater Melbourne have experienced first-hand the impacts of extreme hot weather and bushfires. We have experienced dust storms, hailstorms CONTINUING RISING MORE FREQUENT AND RISING SEA LEVELS WITH and heavy rainfall events resulting in flash-flooding. DAILY TEMPERATURES LONGER HEATWAVES INCREASED RISK OF COASTAL EROSION AND INUNDATION These are climate change impacts that will affect all aspects of our economy, our society and our environment. The consequence of extreme weather is particularly severe for the most vulnerable members of our community. Finding ways to cope with extreme weather impacts and other consequences of climate change is generally referred to as ‘Adaptation’. EXTREME RAINFALL EVENTS RAINFALL EXPECTED TO THE FIRE SEASON IS LONGER EXPECTED TO BECOME CONTINUE TO DECLINE IN AND NUMBER OF VERY HIGH ‘Mitigation’ refers to finding ways to reduce our MORE INTENSE WINTER AND SPRING FIRE DANGER DAYS IN SPRING IS INCREASING emissions. Both approaches are important. Preparing a Regional Climate Change Adaptation Strategy for Greater Melbourne Back to contents Page 3
Melbourne city and the Yarra river Preparing our industries, communities and environments to be able to cope with climate shocks makes good sense. It supports our most vulnerable groups and could reduce future costs. The Victorian Government has provided funding for the local development of six regional Climate Change Adaptation Strategies across Victoria. These strategies will provide an opportunity to identify and prioritise actions for the next five years. The strategies will be regional because our communities know best what the main issues and concerns are at a local level. These regional strategies will align with seven key sector adaptation plans that are also being delivered in Victoria. We all have views of what can and should be done to support our communities and businesses to cope better before, during and after extreme weather events. Preparing an adaptation strategy for our region will be an opportunity to explore and prioritise these ideas.
