Marine ice sheet experiments with the Community Ice Sheet Model [PDF]

The Cryosphere, 2021
Ice sheet models differ in their numerical treatment of dynamical processes. Simulations of marine-based ice are sensitive to the choice of Stokes flow approximation and basal friction law and to the treatment of stresses and melt rates near the ...

Experimental protocol for sea level projections from ISMIP6 stand-alone ice sheet models [PDF]

The Cryosphere, 2020
Projection of the contribution of ice sheets to sea level change as part of the Coupled Model Intercomparison Project Phase 6 (CMIP6) takes the form of simulations from coupled ice sheet–climate models and stand-alone ice sheet models, overseen by the ...

Simulating the Antarctic ice sheet in the late-Pliocene warm period: PLISMIP-ANT, an ice-sheet model intercomparison project [PDF]

The Cryosphere, 2015
In the context of future climate change, understanding the nature and behaviour of ice sheets during warm intervals in Earth history is of fundamental importance.

An ice sheet model validation framework for the Greenland ice sheet [PDF]

Geoscientific Model Development, 2017
We propose a new ice sheet model validation framework – the Cryospheric Model Comparison Tool (CmCt) – that takes advantage of ice sheet altimetry and gravimetry observations collected over the past several decades and is applied here to modeling of the ...

Antarctic ice sheet response to sudden and sustained ice-shelf collapse (ABUMIP)

Journal of Glaciology, 2020
Antarctica's ice shelves modulate the grounded ice flow, and weakening of ice shelves due to climate forcing will decrease their ‘buttressing’ effect, causing a response in the grounded ice.

Climatic Conditions for modelling the Northern Hemisphere ice sheets throughout the ice age cycle [PDF]

Climate of the Past, 2007
The ice sheet-climate interaction as well as the climatic response to orbital parameters and atmospheric CO₂ concentration are examined in order to drive an ice sheet model throughout an ice age cycle.

The hysteresis of the Antarctic Ice Sheet

Nature, 2020
More than half of Earth's freshwater resources are held by the Antarctic Ice Sheet, which thus represents by far the largest potential source for global sea-level rise under future warming conditions1. Its long-term stability determines the fate of our coastal cities and cultural heritage.

Hysteresis of the Antarctic Ice Sheet With a Coupled Climate‐Ice‐Sheet Model

Geophysical Research Letters
The stability of the Antarctic ice sheet under different fixed CO2 levels and orbital configurations is explored using a coupled climate‐ice sheet model, starting from either a pre‐industrial ice sheet or an ice‐free, isostatically rebounded geometry ...

A Gaussian process emulator for simulating ice sheet–climate interactions on a multi-million-year timescale: CLISEMv1.0 [PDF]

Geoscientific Model Development, 2021
On multi-million-year timescales, fully coupled ice sheet–climate simulations are hampered by computational limitations, even at coarser resolutions and when using asynchronous coupling schemes.

PISM-LakeCC: Implementing an adaptive proglacial lake boundary in an ice sheet model [PDF]

The Cryosphere, 2022
During the Late Pleistocene and Holocene retreat of paleo-ice sheets in North America and Europe, vast proglacial lakes existed along the land terminating margins.
