University of New South Wales professor Matthew England has warned of the hidden threat contained in Antarctica if climate change persists.

At an international conference in Sydney yesterday, England said up to 15 metres of ice will melt into the ocean over the next few centuries, making many of the world’s coasts unviable and displacing tens of millions of people.

It comes after a study last year revealed approximately eight islands in the Pacific Ocean have disappeared due to rising sea-levels, with many others being reduced in size due to rising shorelines.
