WASHINGTON — The melting of Antarctica is accelerating at an alarming rate, with about 3 trillion tons of ice disappearing since 1992, an international team of ice experts said in a new study.

In the last quarter century, the southern-most 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 meters), scientists calculated. All that water made global oceans rise about three-tenths of an inch (7.6 millimeters).

From 1992 to 2011, Antarctica lost nearly 84 billion tons of ice a year (76 billion metric tons). From 2012 to 2017, the melt rate increased to more than 241 billion tons a year (219 billion metric tons), according to the study Wednesday in the journal Nature .

“I think we should be worried. That doesn’t mean we should be desperate,” said University of California Irvine’s Isabella Velicogna, one of 88 co-authors. “Things are happening. They are happening faster than we expected.”

Part of West Antarctica, where most of the melting occurred, “is in a state of collapse,” said co-author Ian Joughin of the University of Washington.
