Dark Land Surfaces Allow for Refugia That Could Support Photosynthetic Life on the Surface of Snowball Earth

Journal of Geophysical Research: Atmospheres, Volume 131, Issue 13, 16 July 2026.
Abstract Photosynthetic eukaryotic algae survived the Neoproterozoic Snowball Earth events, indicating that liquid‐water refugia existed somewhere on the surface. We examine the potential for refugia at the coldest time of a snowball event, before CO2 had risen and with high‐albedo ice on the frozen ocean, before it became darkened by dust deposition ...

A Vast Valley Network Beneath the Greenland Ice Sheet

Geophysical Research Letters, Volume 53, Issue 13, 16 July 2026.
Abstract Mapping subglacial topography along the margin of the Greenland Ice Sheet was revolutionized by reconciling measurements of ice thickness and surface velocity using the principle of mass conservation. Despite evidence that many subglacial valleys resolved by that method extend upstream, it cannot be applied to the ice sheet's slower‐flowing ...

Weak 21st‐Century AMOC Response to Greenland Meltwater in a Strongly Eddying Ocean Model

Geophysical Research Letters, Volume 53, Issue 13, 16 July 2026.
Abstract Climate models project that the Atlantic Meridional Overturning Circulation (AMOC) will weaken in the 21st century, but the magnitude is highly uncertain. Some of this uncertainty is structural, as most climate models neglect increasing meltwater from the Greenland ice sheet and do not explicitly capture mesoscale ocean eddies.

Investigating antarctic ice-sheet vulnerability to internal ice-sheet processes

, 2019
The Weddell Sea sector of West Antarctic Ice Sheet may be increasingly vulnerable to melting specifically close to the grounding line through atmospheric warming and modifications in ocean circulation. This project investigates the complexity of ice-sheet stability at and close to the grounding line in the Institute, Möller and Foundation Ice Streams ...
