The latest edition of the Proceedings of the Royal Society of Victoria is now online, featuring a new species of calcareous sponge discovered in Geelong, a spectacular new H5 meteorite in Maryborough, an account of Indigenous meteorological knowledge using stellar scintillation, a reclassification of fossil graptolites from the early Bendigonian, a case for regulated investment in a resilient electricity network, an account of the Bureau of Meteorology’s new extreme heatwave event forecasting service, and a discussion on whether a similar service might be required for cold extremes.
Associate Professor Stephen Gallagher has spent months at sea over the past several years, drilling into the past to obtain a record of Australian geological history. The expedition set out to recover a 5-million-year record of the Australian climate – and surpassed their expectations by uncovering 50 million years. Gallagher was pleasantly surprised at the gems of information discovered on changes to aridity, sea levels, and monsoon cycles that the core samples revealed.
Imagine sweltering through four days of 40°C – 50°C temperatures. Or not being able to get home because flooding has disrupted rail and road networks. With the changing global climate, such scenarios are possible within the next 20 years. The question is: will Victoria be resilient to these challenges? This is the problem senior government officials and researchers gathered together to answer. RSV’s inaugural Future Thinking Forum saw representatives from over 35 agencies, including universities and government, meet to discuss Victoria’s capacity to cope with extreme weather. The proceedings began with the description of two possible extreme weather scenarios: a severe heatwave and an extreme flooding and wind event. These scenarios were not one of a distant future, nor were they from a dystopian, Eco-Disaster novel. They could be Victoria’s reality within the next two decades.
