Future of Antarctica’s Larsen C ice-shelf will have consequences for sea level rise world-wide

 Scientists know the surface of the Larsen C ice shelf in Antarctica is
melting, making it vulnerable to collapse. For the first time, we can rank
the most important causes of melting over the recent past.

In a new two-part paper in Journal of Geophysical Research: Atmospheres, we show how
the amount of energy reaching the ice from the sun is the dominant factor,
followed by warm winds, clouds and weather patterns. These drivers of
melting can interact and overlap to reinforce or counteract each other, so
it is a complex picture.

Understanding what is causing melting over Larsen
C is vital as it will help predict the future of the ice shelf, which will
have knock-on consequences for sea levels worldwide. In 2002, Larsen C’s
neighbouring ice shelf, Larsen B, experienced melting so severe that it
eventually caused the shelf to collapse completely. Larsen C restrains
glaciers that contain enough ice to raise global sea levels by around 22mm.
