West Antarctic Ice Sheet Collapse...

An alarming look at the collapse of West Antarctica's Ice Shelves and Glaciers!

Antarctica is the engine room that powers the world's climate.

The collapse of the Western Antarctica ice sheet is already under way and is unstoppable, two separate teams of scientists said on Monday.

The glaciers' retreat is being driven by climate change and is already causing sea-level rise at a much faster rate than scientists had anticipated.

The loss of the entire western Antarctica ice sheet could eventually cause up to 4 metres (13ft) of sea-level rise, devastating low-lying and coastal areas around the world. But the researchers said that even though such a rise could not be stopped, it is still several centuries off, and potentially up to 1,000 years away.

The two studies, by Nasa and the University of Washington, looked at the ice sheets of western Antarctica over different periods of time.

The Nasa researchers focused on melting over the last 20 years, while the scientists at the University of Washington used computer modelling to look into the future of the western Antarctic ice sheet.
