|Antarctica's Ice Sheet is Melting Three Times Faster Than Before|
The melting of Antarctica is accelerating at an alarming rate, with about 3 trillion tonnes of ice disappearing since 1992, an international team of ice experts said in a new study by a team of scientists working with NASA and the European Space Agency. In the last quarter century, the southernmost continent's ice sheet—a key indicator of climate change—melted into enough water to cover Texas to a depth of nearly 13 feet (4 m), scientists calculated. All that water made global oceans rise about three-tenths of an inch (7.6 mm). From 1992 to 2011, Antarctica lost nearly 84 billion tonnes of ice a year (76 billion metric tonnes). From 2012 to 2017, the melt rate increased to more than 241 billion tonnes a year (219 billion metric tonnes), according to the study published in the journal Nature.
