Nonlinear Dynamics May Lead to Faster Retreat of Antarctic Ice

by Minghua Zhang 14 April 202514 April 2025

The Antarctic ice sheet behaves like a non-Newtonian fluid and may be more nonlinear than previously thought. This impacts its future stability and requires revisions to predictions of sea level rise.

Glacier Intervention Research Isn’t Just for Glaciologists

by Kenneth D. Mankoff, Christina Hulbe, Sławek Tulaczyk, Francesca Marzatico and Tiffany Morrison 9 January 202524 March 2025

Prospects for mitigating sea level rise by slowing flows of glacial ice into the ocean are worthy of research, but this work must involve all rights holders and stakeholders.

Mantle Motion Matters for Mapping Modern (and Ancient) Ice

by Alka Tripathy-Lang 11 December 202411 December 2024

Mantle motions have major effects on topography and the distribution of ice sheets. The motions are key for researchers trying to properly parse past mantle movement.
