Rising seas may put $300b of property at risk: scientists
""If the climate science is right - and that's that we can expect a sea-level rise of somewhere between 80 centimetres and 1.1 metres by the year 2100 - that lifestyle is under threat," he said.
"Also under threat are the properties that are going to be developed in vulnerable areas along the coast which are being approved at the moment in states all around Australia."
Rising sea levels are a direct result of melting glaciers, and according to some of the most recent peer-reviewed reports, the melt is accelerating.
John Church is from the CSIRO's atmospheric research section and a lead author on sea-level rise for the UN's chief science body, the Intergovernmental Panel on Climate Change.
"The Greenland ice sheet is increasing its surface melt ... if we are to avoid some of the extreme scenarios, to avoid the complete melting of the Greenland ice sheet, it's urgent that we start mitigating or reducing emissions significantly and in a sustained way into the future," Dr Church said.
Australia's Climate Commission has done modelling on a rise above one metre, which it says could be devastating for all Australian coastal cities, as well as the 6 million people outside the main population centres.
For example, in Sydney it forecasts that runways at the main domestic airport could be inundated and terminals flooded."
