Antarctic last interglacial isotope peak in response to sea ice retreat not ice-sheet collapse

Nature Communications, 2016
The peak in Antarctic ice core isotope values, 128,000 years before present, was concurrent with a significantly warmer-than-present Antarctic climate.

Changes in ice dynamics and mass balance of the Antarctic ice sheet [PDF]

Philosophical Transactions of the Royal Society A: Mathematical, Physical and Engineering Sciences, 2006
The concept that the Antarctic ice sheet changes with eternal slowness has been challenged by recent observations from satellites. Pronounced regional warming in the Antarctic Peninsula triggered ice shelf collapse, which led to a 10-fold increase in glacier flow and rapid ice sheet retreat.

Does Polar Warming Asymmetry Exist in Bathy‐Planet Experiments?

Geophysical Research Letters, Volume 53, Issue 17, 16 September 2026.
Abstract Ocean bathymetry and continental geometry shape ocean circulation, but whether these geographic constraints can sustain polar warming asymmetry in a fully coupled climate system remains unclear. Here we construct a fully coupled “bathy‐planet” configuration (BATHY), in which continental topography is removed and most land surfaces are replaced

The Source of Arctic Precipitation in HadGEM3‐GC5

Journal of Geophysical Research: Atmospheres, Volume 131, Issue 17, 16 September 2026.
Abstract Snow and rain are increasing in the Arctic. Climate model projections indicate a 50% increase in precipitation by the end of the century. This increase is driven by increased local evaporation following reduced sea ice coverage alongside enhanced global evaporation and transport into the Arctic.

An improved retrieval method for liquid water content of the Antarctic ice sheet using SMOS data

Geocarto International
With global climate warming, Antarctic ice sheet melting has garnered increasing attention, as changes in liquid water content (LWC) significantly affect sea level rise and regional climate.

Measurement of Antarctic ice sheet movements in vicinity of Syowa Station through one year of GPS observations

Antarctic Record, 2010
We conducted GPS observations on the Antarctic ice sheet in the vicinity of Syowa Station, during wintering of the 48th Japanese Antarctic Research Expedition (JARE-48). Continuous GPS data for about one year was obtained for the first time.

Approximating ice sheet – bedrock interaction in Antarctic ice sheet projections

Abstract. The bedrock response to a melting ice sheet provides a negative feedback on ice mass loss. When modelling the future behaviour of the Antarctic Ice Sheet, accounting for the impact of bed deformation on ice dynamics can reduce predictions of future sea level rise by up to 40 % in comparison with scenarios that assume a rigid Earth.
