Melbourne experienced a hail storm March 6th that has done hundreds of millions if not billions of dollars of damage. The storm has been labelled a "once in a century" event. What's not been mentioned is that the storm fits the predicted pattern of the impact of Climate Change on South East Australia.
Whilst the sceptics bellow their crap in the media and on the internet, the recent storm fits into a pattern of weather in Melbourne and Victoria that supports the growing impact of climate change on our region. The predicted impacts of climate change on South East Australia include changes to rain patterns and more extreme weather events.
Victoria is in the midst of a long term drought. This fits the predicted changes of more extended dry periods for Melbourne interspersed with major rain events. In addition to the lemon sized hail on Saturday was a major rain event which caused flash flooding across the city.
Only about 12 months ago Victoria was experiencing one of the worse heat waves and droughts on record culminating in Melbourne's hottest day ever of 46 degrees on Black Saturday 2009, a day when 173 people perished.
Even though neither event can be 100% attributed to climate change, they fit the pattern of freak "once a century" events happening more and more often in South East Australia as the global temperature rises. Interesting there has not been one mention of climate change in all of the mainstream coverage of the event as even a possible contributing factor to the storm even though one reads in the Herald Sun that experts say the storm is more typical of tropical weather patterns. eanwhile down in the Latrobe Valley we continue to burn brown coal as politicians of both major parties adopt a business as usual approach. If events like this become more common the "economic costs" of doing nothing start to be put in perspective.
