eavily populated areas of Australia's coastal capitals will slip under the waves along with large swathes of megacities across the world even if an upcoming climate summit limits global warming to 2 degrees Celsius, scientists say.

An increase of 4C — humanity's current trajectory — would cover areas lived on by more than 600 million people, the study said.
