Status of Polar Blue Carbon: Toward Recognition and Integration in Marine Policy. [PDF]

Glob Chang Biol
Carbon‐rich habitats in polar regions are globally important, as uptake of CO2 by marine systems is shifting toward the poles. Changing conditions are exposing these regions to anthropogenic exploitation. Timely policy intervention can protect these habitats to prevent further emissions and further integration of polar blue carbon in management ...

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.

Atmospheric Microbial Transport to Antarctica and Its Ecological Implications: A Systematic Review. [PDF]

Environ Microbiol
Atmospheric transport to Antarctica operates via long‐range advection, marine aerosolization, and local resuspension, acting as a strict ecological filter. This selective barrier could actively shape local ecosystems by seeding them with functionally distinct, stress‐adapted microbial pioneers capable of surviving extreme conditions.

Evaluation of Riming in the P3‐2ice Microphysics Scheme: A Case Study of Cold‐Air Outbreak Snowfall in Eastern China

Journal of Geophysical Research: Atmospheres, Volume 131, Issue 17, 16 September 2026.
Abstract Using the multi‐frequency radar suite, ground‐based observations, and the Weather Research and Forecasting (WRF) model with the Predicted Particle Properties microphysics scheme with the version of two‐ice category (P3‐2ice), we study the characteristics of a cold‐air outbreak (CAO) snowfall event on 6–7 December 2024.

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.

Refining the Simulation of Mixed‐Phase Clouds Over Coastal Antarctica With a Tailored Ice Nucleating Particle Parameterization

Journal of Geophysical Research: Atmospheres, Volume 131, Issue 17, 16 September 2026.
Abstract Climate models have substantial biases in downwelling shortwave radiation over the Southern Ocean (SO) and Antarctica, primarily due to their inability to accurately represent the frequent occurrence of low‐level mixed‐phase clouds. Building on the evaluation of the Unified Model (UM) Regional Atmosphere and Land version 3 (RAL3), this study ...
