Anthropogenic climate change is likely to cause continuing global sea level rise, but some processes within the Earth system may mitigate the magnitude of the projected effect. Regional and global climate models simulate enhanced snowfall over Antarctica, which would provide a direct offset of the future contribution to global sea level rise from cryospheric mass loss and ocean expansion. Uncertainties exist in modelled snowfall, but even larger uncertainties exist in the potential changes of… Expand

Effect of prescribed sea surface conditions on the modern and future Antarctic surface climate simulated by the ARPEGE AGCM
Owing to increase in snowfall, the Antarctic Ice Sheet surface mass balance is expected to increase by the end of current century. Assuming no associated response of ice dynamics, this will be a… Expand
Effect of prescribed sea surface conditions on the modern and future Antarctic surface climate simulated by the ARPEGE atmosphere general circulation model

Quantifying the potential future contribution to global mean sea level from the Filchner-Ronne basin, Antarctica
Abstract. The future of the Antarctic Ice Sheet in response to climate warming is one of the largest sources of uncertainty in estimates of future changes in global mean sea level (∆GMSL). Mass loss… Expand
High variability of climate and surface mass balance induced by Antarctic ice rises
Abstract Ice rises play key roles in buttressing the neighbouring ice shelves and potentially provide palaeoclimate proxies from ice cores drilled near their divides. Little is known, however, about… Expand
The Future Sea-Level Contribution from Antarctica: Projections of Solid Ice Discharge
Future sea level change has a strong impact on the livelihood of a large share of the world’s population. Sea-level projections are thus of great importance with respect to an assessment of necessary… Expand
Exploration of Antarctic Ice Sheet 100-year contribution to sea level rise and associated model uncertainties using the ISSM framework
Abstract. Estimating the future evolution of the Antarctic Ice Sheet (AIS) is critical for improving future sea level rise (SLR) projections. Numerical ice sheet models are invaluable tools for… Expand
Projecting Antarctic ice discharge using response functions from SeaRISE ice-sheet models
Abstract. The largest uncertainty in projections of future sea-level change still results from the potentially changing dynamical ice discharge from Antarctica. While ice discharge can alter through… Expand
The multi-millennial Antarctic commitment to future sea-level rise
TLDR
A coupled ice-sheet/ice-shelf model is used to show that if atmospheric warming exceeds 1.5 to 2 degrees Celsius above present, collapse of the major Antarctic ice shelves triggers a centennial- to millennial-scale response of the Antarctic ice sheet in which enhanced viscous flow produces a long-term commitment to sea-level rise.
