Decoupling Hydroclimatic Controls on Displacement of Retrogressive Thaw Slumps in Qinghai‐Tibet Plateau

Geophysical Research Letters, Volume 53, Issue 6, 28 March 2026.
Abstract The retrogressive thaw slumps (RTS), a prevalent form of thermokarst hazard in permafrost regions, are increasing in both number and extent under contemporary changing environments. On the Qinghai‐Tibet Plateau, RTS threaten transportation infrastructure and disrupt ecosystems.

Frozen Soil Hydrological Processes and Their Effects: A Review and Synthesis

Reviews of Geophysics, Volume 64, Issue 1, March 2026.
Abstract Frozen soils, including seasonally frozen ground and permafrost, are rapidly changing under a warming climate, with cascading effects on water, energy, and carbon cycles. We synthesize recent advances in the physics, observation, and modeling of frozen‐soil hydrology, emphasizing freeze–thaw dynamics, infiltration regimes and preferential flow,

Measurement of Gas Fraction and Gas Permeability of Thawing Permafrost Caused by Climate Change

Earth's Future, Volume 14, Issue 3, March 2026.
Abstract Thawing of permafrost due to climate change is known to release gases such as the climate drivers carbon dioxide and methane, as well as the carcinogen radon. Gas permeability is extremely low in fully frozen permafrost and can be considered both to function as a seal preventing subsurface gases being released, and to prevent the creation of ...

Metagenomic Analysis of Thawing Permafrost Highlights Links Between Carbon and Nitrogen Cycling Processes in Abrupt Thaw Simulation

Journal of Geophysical Research: Biogeosciences, Volume 131, Issue 3, March 2026.
Abstract Abrupt permafrost thaw events are projected to contribute up to 40% of permafrost carbon (C) release to the atmosphere. They involve sudden hydrological shifts within the soil column; however, the exact microbial functional pathway shifts induced by these events remain cryptic. To investigate how C and nutrient cycling processes differ in thaw

The Arctic Coastal Erosion Model: Overview, Developments, and Calibration at Drew Point, Alaska

Journal of Advances in Modeling Earth Systems, Volume 18, Issue 3, March 2026.
Abstract Permafrost coastlines are experiencing significant erosion as polar amplification has enhanced the effects of climate change in the Arctic. Warmer temperatures are increasing thermo‐denudation and more energetic oceans are increasing thermo‐abrasion in unlithified, ice‐bonded permafrost coastlines which comprise at least 40% of the circum ...

Improving SAR‐Based Classification of Arctic Lake, Bay and Lagoon Ice by Accounting for Under Ice Water Salinity

Water Resources Research, Volume 62, Issue 3, March 2026.
Abstract Arctic lake, bay and lagoon ice regimes play a crucial role in understanding permafrost stability, hydrology, and carbon cycling in permafrost regions. This study integrates field and Synthetic Aperture Radar (SAR) data from Sentinel‐1 to improve the classification of Arctic lake, bay and lagoon ice regimes, with a particular focus on the ...

Retrogressive Thaw Slumps Produce a Changing Disturbance Regime for Arctic Stream Invertebrates

Global Change Biology, Volume 32, Issue 3, March 2026.
Climate change is causing permafrost to thaw, resulting in the formation of large craters in the ground called thaw slumps, which deposit sediments and nutrients into rivers and continually impact stream ecosystems over time. We returned to slump impacted streams 10 years after an initial sample period and found that slumps permanently change streams ...

Freeze‐Thaw Cycling Accelerated Olivine Weathering and Water Sequestration on Icy Mars

Geophysical Research Letters, Volume 53, Issue 4, 28 February 2026.
Abstract Geological evidence and paleoclimate models suggest that freeze‐thaw (FT) cycling has played a pivotal role in shaping the Martian surface composition throughout geological time. Here we show the experimental investigation of the sulfuric acid weathering of olivine under simulated FT conditions (193–293 K).

Spatial and Temporal Variability of Microbial Nitrogen Cycling Genes in Arctic Streams

Global Biogeochemical Cycles, Volume 40, Issue 2, February 2026.
Abstract The Arctic is undergoing rapid climate change, with thawing permafrost and shifts in vegetation altering nitrogen (N) delivery into streams. These changes can significantly affect microbial biofilm diversity and functional roles, yet knowledge of streambed microbial biofilms remains scarce across the Arctic.
