Doomsday Glacier and sea level rise

An Antarctic glacier, the size of Great Britain, is melting at an alarming rate, according to new research. Nick-named the Doomsday glacier, Thwaites glacier flows off the west of the Antarctic and is dumping billions of tonnes of ice into the ocean, pushing up global sea-levels. The melt has increased from 10 billion tonnes of ice a year in the 1990s, to 80 billion tonnes a year today. The British Antarctic Survey (BAS) has been mapping warm seawater cavities which are eroding the glacier, some of which are half the size of the Grand Canyon. Dr Kelly Hogan from the British Antarctic Survey is one of the team surveying Thwaites, whose research has been published in the Cryosphere journal.
