Antarctic ice loss has doubled: study
Data on change in the height of ice from 2010 - 2013 was compared to that from 2005 - 2010
Antarctica is shedding 160 billion tonnes a year of ice into the ocean, twice the amount of a few years ago, according to new satellite observations. The ice loss is adding to the rising sea levels driven by climate change and even east Antarctica is now losing ice.
The new revelations follow the announcement last week that the collapse of the western Antarctica ice sheet has already begun and is unstoppable, although it may take many centuries to complete.
Global warming is pushing up sea level by melting the world's major ice caps and by warming and expanding oceans. The loss of the entire western Antarctica ice sheet would eventually cause up to 4 metres of sea-level rise, devastating low-lying and coastal areas around the world.
