Scientists from around the world calculate that in the last quarter century, the southern-most continent's ice sheet melted into enough water to cover Texas to a depth of nearly 13 feet.

The study says that from 1992 to 2011, Antarctica lost nearly 84 billion tons of ice a year. From 2012 to 2017, the melt rate increased to more than 241 billion tons a year.

The study in Wednesday's journal Nature is part of an international effort to assess vulnerable ice sheets in Antarctica and Greenland, which are key indicators of climate change.
