Returning Climate to Present Day May not Reduce Antarctic Mass Loss

Journal of Geophysical Research: Earth Surface, Volume 131, Issue 10, October 2026.
Abstract Using the BISICLES ice sheet model, we explore the Antarctic Ice Sheet's response over the 22nd century under two climate scenarios. In the return scenario, climate forcing is returned to present‐day levels (2015) in either 2050 or 2100 and then held constant until 2200.

Separating glacial isostatic adjustment and ice-mass change signals in Antarctica using satellite data

, 2017
The main goal of this thesis involves the development of a refined methodology toseparate the mass change signals associated with glacial isostatic adjustment (GIA)from those of surface ice/firn by exploiting the strengths of independent data sets,such ...

Glacial-Isostatic Adjustment-II. The Inverse Problem [PDF]

Geophysical Journal of the Royal Astronomical Society, 2007
Summary The principle of correspondence is invoked to determine Laplace transform domain solutions to the surface mass loading problem for radially stratified visco-elastic (Maxwell) spheroids. These Laplace transform domain solutions are expressed in terms of visco-elastic analogues of the conventional surface load Love numbers of elasticity. These

Ice Sheets Without Dynamic Topography

Geophysical Research Letters
Dynamic topography results in uplift and subsidence events on Earth's surface with amplitudes on the order of a kilometer. These vertical motions are known to have influenced ice sheet evolution, but how dynamic topography has controlled the current ...

A Regional Intercomparison of Ice Sheet Mass Balance Estimates of the Northwest Greenland Ice Sheet

Journal of Geophysical Research: Earth Surface, Volume 131, Issue 10, October 2026.
Abstract Changes in ice sheet mass manifest as changes in ice flow, ice thickness, and gravitational attraction. These parameters can be measured from space and used to track Greenland's contribution to sea level rise independently from each other. While an excellent level of agreement between these satellite techniques has been demonstrated at the ice

Organic Matter Dynamics and Biogeochemical Signatures in Lakes From the Prairies to Tundra in Western Canada

Journal of Geophysical Research: Biogeosciences, Volume 131, Issue 10, October 2026.
Abstract Climate‐driven poleward shifts of terrestrial ecosystems are expected to alter organic matter inputs and biogeochemical processes in northern lakes. In regions lacking long‐term observations, latitudinal gradients provide valuable space‐for‐time substitutions for predicting these changes.

Influence of glacial isostatic adjustment upon current sea level variations in the Mediterranean

, 2009
Present-day sea level variations in the Mediterranean depend on various factors, including recent climatic forcing, tectonic activity, anthropogenic effects, and glacio-isostatic adjustment.

Relationship between glacial isostatic adjustment and gravity perturbations observed by GRACE [PDF]

, 2016
The Gravity Recovery and Climate Experiment space gravity mission provides one of the principal means of estimating present-day mass loss occurring in polar regions.

GNET Derived Mass Balance and Glacial Isostatic Adjustment Constraints for Greenland

Geophysical Research Letters
Monitoring the Greenland mass balance (GMB) is crucial in the context of global sea level rise. Currently, three main methods are used to measure GMB, with the primary source of uncertainty arising from the glacial isostatic adjustment (GIA) contribution.

Satellite data reveal details of glacial isostatic adjustment in the Amundsen Sea Embayment, West Antarctica [PDF]

The Cryosphere
The instability of the West Antarctic Ice Sheet (WAIS) is a tipping element in the climate system, and it is mainly dictated by changes in the ice flow behaviour of the outflow glaciers in the Amundsen Sea Embayment (ASE).
