Spaceborne Far‐Infrared Signal Simulations Over the Antarctic Plateau With Temperature‐Dependent Ice Cloud Optical Properties

Journal of Geophysical Research: Atmospheres, Volume 131, Issue 17, 16 September 2026.
Abstract Longwave cloud radiative effects significantly influence variability in global and regional Earth systems. However, there have been very few, if any, measurements of the far‐infrared (FIR) radiation over the polar regions, where about half of the outgoing longwave radiation is in the FIR spectrum. This motivated the Polar Radiant Energy in the

Glacier‐Climate Feedbacks Modulate Last Glacial Maximum Dust Cycle Over the Third Pole

Geophysical Research Letters, Volume 53, Issue 17, 16 September 2026.
Abstract Geological records indicate only a modest Last Glacial Maximum (LGM) increase in dust deposition over the Third Pole (TP), in contrast to the order‐of‐magnitude rise at high latitudes. Existing climate simulations, which generally prescribe present‐day or no TP glaciers, have struggled to reproduce this muted response.

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

Evaluating the Role of Kernel Choice on Radiative Feedback Estimates

Geophysical Research Letters, Volume 53, Issue 17, 16 September 2026.
Abstract Radiative feedbacks are important for understanding climate sensitivity, yet estimates vary widely across climate models. Feedbacks are often computed using the radiative kernel technique, which uses pre‐calculated radiative sensitivities (kernels) derived from different models and base states. While much attention has been given to intermodel

Permafrost Degradation Drives Shifts in Chemostasis and Stream Geochemistry in the McMurdo Dry Valleys, Antarctica

Geophysical Research Letters, Volume 53, Issue 17, 16 September 2026.
Abstract In the McMurdo Dry Valleys, Antarctica's largest ice‐free area, the stream channels consist of rock and sediment that are underlain by permafrost. Substantial permafrost degradation and channel erosion occurred in January 2012 on the west branch of Crescent Stream, while the east branch remained unaffected.
