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.

Antarctic Ice Sheet paleo-constraint database [PDF]

Earth System Science Data, 2023
We present a database of observational constraints on past Antarctic Ice Sheet changes during the last glacial cycle intended to consolidate the observations that represent our understanding of past Antarctic changes and for state-space estimation and ...

Future Antarctic bed topography and its implications for ice sheet dynamics [PDF]

Solid Earth, 2014
The Antarctic bedrock is evolving as the solid Earth responds to the past and ongoing evolution of the ice sheet. A recently improved ice loading history suggests that the Antarctic Ice Sheet (AIS) has generally been losing its mass since the Last ...

From short-term uncertainties to long-term certainties in the future evolution of the Antarctic Ice Sheet [PDF]

Nature Communications
Robust projections of future sea-level rise are essential for coastal adaptation, yet they remain hampered by uncertainties in Antarctic ice-sheet projections–the largest potential contributor to sea-level change under global warming.

Solid Earth change and the evolution of the Antarctic Ice Sheet [PDF]

Nature Communications, 2019
The evolution of the Antarctic Ice Sheet is driven by a combination of climate forcing and non-climatic feedbacks. In this review, the authors focus on feedbacks between the Antarctic Ice Sheet and the solid Earth, and the role of these feedbacks in ...

Geologically constrained 2-million-year-long simulations of Antarctic Ice Sheet retreat and expansion through the Pliocene [PDF]

Nature Communications
Pliocene global temperatures periodically exceeded modern levels, offering insights into ice sheet sensitivity to warm climates. Ice-proximal geologic records from this period provide crucial but limited glimpses of Antarctic Ice Sheet behavior.

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 ...

Sensitivity of the Antarctic ice sheets to the warming of marine isotope substage 11c [PDF]

The Cryosphere, 2021
Studying the response of the Antarctic ice sheets during periods when climate conditions were similar to the present can provide important insights into current observed changes and help identify natural drivers of ice sheet retreat. In this context, the
