Paleoceanography and Paleoclimatology, 2021
During the Last Interglacial, approximately 129 to 116 ka (thousand years ago), the Arctic summer climate was warmer than the present, and the Greenland Ice Sheet retreated to a smaller extent than its current state. Previous model‐derived and geological

It is only in exceptional cases that the shape of an ice sheet can be calculated by analytical methods. Some examples of situations in which this is possible will be discussed in chapter 6. In most cases numerical methods have to be used, particularly when we are not only interested in steady states, but also want to compute the transient behaviour of ...

Antarctic ice-sheet hysteresis in a three-dimensional hybrid ice-sheet model
2020<p>Ice sheets, in particular the Antarctic Ice Sheet (AIS), are considered as potential tipping elements (TEs) of the Earth system. The mechanism underlying tipping is the existence of positive feedbacks leading to self-amplification processes that, once triggered, dominate the dynamics of the system.

Glacier mass loss related to ice flow is a quantitative factor that controls sea level rise and global warming. Ice flow is attributed to the complicated interaction between grounding line migration, calving basal friction, and topography. Previous studies using massive geophysical observation, including IPR (Ice Penetrating Radar), InSAR ...

Historic simulations of the Antarctic Ice Sheet with the Parallel Ice Sheet Model
2021<p>Large uncertainties in Antarctic sea level projections are related to ocean-driven melting (Seroussi et al., 2020; Jourdain et al., 2020; Reese et al., 2020; Edwards et al., in press) and the marine ice sheet instability (Robel et al., 2019).

Coupling ice-sheet and climate models for simulation of former ice sheets
2003Publisher Summary This chapter explores the development of coupled climate and ice-sheet models over the past two decades, discusses the current technical and physical capabilities of models, and identifies future work for developing a better understanding of ice-climate events that have punctuated Earth history.

Modelling the dynamics of ice sheets
Progress in Physical Geography: Earth and Environment, 1993Although the mechanics and qualitative dynamics of grounded ice sheets and ice shelves are fairly well understood, this is not true for the transition between the two. In consequence, the existence and nature of any grounding line instability have yet to be established.
