One of the Earth's continents is 'rising'

What happens in Antarctica has global implications

Antarctica is losing weight, allowing the continent to rise from the ocean much like a long-suppressed sponge is freed and returns to its original size.

The weight released is the ice itself.

The process taking place in Antarctica is called post-glacial uplift, and research predicts that what happens there will have huge implications for future global sea level rise.

"With nearly 700 million people living in coastal areas worldwide and the potential cost of sea level rise due to melting ice reaching trillions of dollars by the end of this century, understanding the domino effect of melting ice in Antarctica is extremely important," said glaciologist Natalya Gomez of McGill University (Canada).

To find out what's happening in Antarctica, Gomez and his colleagues used 3D models to simulate sea level rise caused by changes in Antarctic land mass under different scenarios.

The results show that if temperature increases are kept low, the Antarctic scenario could result in an additional 1.7 m of sea level rise by 2500 compared to current data.

However, this figure could increase to 19.5 m if humans continue to allow global warming to develop unchecked.
