Mass balance of the Antarctic Ice Sheet from 1992 to 2017

The Antarctic Ice Sheet is an important indicator of climate change and driver of sea-level rise. Here we combine satellite observations of its changing volume, flow and gravitational attraction with modelling of its surface mass balance to show that it lost 2,720± 1,390 billion tonnes of ice betwee...
