Satellite observations over the past two decades have revealed increasing loss of grounded
ice in West Antarctica, associated with floating ice shelves that have been thinning. Thinning
reduces an ice shelf's ability to restrain grounded-ice discharge, yet our understanding of the
climate processes that drive mass changes is limited. Here, we use ice-shelf height data
from four satellite altimeter missions (1994–2017) to show a direct link between ice-shelf
height variability in the Antarctic Pacific sector and changes in regional atmospheric …
