The uncertain future of the Antarctic Ice Sheet

F Pattyn, M Morlighem - Science, 2020 - science.org
The Antarctic Ice Sheet is losing mass at an accelerating pace, and ice loss will likely
continue over the coming decades and centuries. Some regions of the ice sheet may reach …

Instantaneous Antarctic ice sheet mass loss driven by thinning ice shelves

GH Gudmundsson, FS Paolo… - Geophysical …, 2019 - Wiley Online Library
Recent observations show that the rate at which the Antarctic ice sheet (AIS) is contributing
to sea level rise is increasing. Increases in ice‐ocean heat exchange have the potential to …

Annual mass budget of Antarctic ice shelves from 1997 to 2021

BJ Davison, AE Hogg, N Gourmelen, L Jakob… - Science …, 2023 - science.org
Antarctic ice shelves moderate the contribution of the Antarctic Ice Sheet to global sea level
rise; however, ice shelf health remains poorly constrained. Here, we present the annual …

Meeting user needs for sea level rise information: A decision analysis perspective

J Hinkel, JA Church, JM Gregory, E Lambert… - Earth's …, 2019 - Wiley Online Library
Despite widespread efforts to implement climate services, there is almost no literature that
systematically analyzes users' needs. This paper addresses this gap by applying a decision …

Ice viscosity is more sensitive to stress than commonly assumed

JD Millstein, BM Minchew, SS Pegler - Communications Earth & …, 2022 - nature.com
Accurate representation of the viscous flow of ice is fundamental to understanding glacier
dynamics and projecting sea-level rise. Ice viscosity is often described by a simple but …

Marine ice sheet instability amplifies and skews uncertainty in projections of future sea-level rise

AA Robel, H Seroussi, GH Roe - Proceedings of the …, 2019 - National Acad Sciences
Sea-level rise may accelerate significantly if marine ice sheets become unstable. If such
instability occurs, there would be considerable uncertainty in future sea-level rise projections …
