Bondi beach will shrink to a thin ribbon of sand and extreme storm surges would reach the top of its concrete sea wall, research commissioned by the local council shows.
The latest report from the Intergovernmental Panel on Climate Change, released on Friday, found the sea level would rise and could be expected to be up to 80 centimetres higher by the end of the century.
In the case of an 80-centimetre rise in sea levels, high tides would regularly flood parts of many Sydney suburbs that are close to water, including sections of Annandale, Mosman, Marrickville, Brighton-le-Sands, Sylvania Waters, Five Dock and Narrabeen.
Rob Brander, a senior lecturer at the University of NSW specialising in coastal geomorphology, said Sydney’s coastal regions faced significant impacts from rising sea levels.
“If a beach shifts landward, it hasn’t got many places to go,” Dr Brander said. “Beaches will get narrower and low-lying coastal properties will face damage.”Sydney Morning Herald, 29 Sep 2013
