Victoria’s Point Lonsdale beach – just one example of rising sea levels

Rising sea levels, stronger waves speeding up Victorian coastal erosion, CSIRO says, ABC News 30 Oct 16 By Joanna Crothers Rising sea levels and more frequent storms are increasing the rate of erosion across Australia’s southern coastline, the CSIRO has said, while locals at one Victorian beach are concerned it is not safe for summer holidaymakers.

Kathleen McInnes, a CSIRO sea level and coastal extremes expert, said more powerful waves were also contributing to the problem. “Sea levels have risen some 20 centimetres over the past 100 years, and are currently rising at about three millimetres per year,” she said. “There is also evidence that winds in the southern ocean are intensifying and this is driving a positive trend in wave energy reaching our coastline. “So this is creating a double whammy for coastal impacts.”

Individual storms have also become more frequent and intense, meaning beaches do not have as much time to recover after a harsh winter.”They’re driving higher waves which means a higher wave energy [is] reaching the shore,” Ms McInnes said.

Point Lonsdale beach ‘dangerous’, not ready for holidays The beachfront at Point Lonsdale, on the Bellarine Peninsula, has been badly eroded over the past decade and local residents said there was a risk children could slipping and cracking their heads open near the seawall…….http://www.abc.net.au/news/2016-10-30/rising-sea-levels-speeding-up-coastal-erosion-csiro-says/7972924
