Modelling Rapid Changes in Ice-Rich Permafrost Landscapes

, 2018
Ice-rich permafrost is estimated to underlie 20% of the Northern hemisphere’s permafrost region. It is particularly vulnerable to thawing processes referred to as “thermokarst”, which manifest in emerging characteristic landforms and rapidly changing landscapes.

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,

Remote sensing of rapid permafrost landscape dynamics

, 2017
The global climate is warming and the northern high latitudes are affected particularly rapidly. Large areas of this region, or 24% of the northern hemisphere, are influenced by perennially frozen ground or permafrost. As permafrost is predominantly dependent on cold mean annual air temperatures, climate warming threatens the stability of permafrost ...

Glacier‐Atmosphere Interactions and Feedbacks in High‐Mountain Regions ‐ A Review

Reviews of Geophysics, Volume 64, Issue 1, March 2026.
Abstract Mountain glaciers are among the natural systems most vulnerable to climate change. However, their interactions with the atmosphere are complex and not fully understood. These interactions can trigger rapid adjustments and climate feedbacks that either amplify or attenuate atmospheric signals, influencing both glacier response and large‐scale ...

North American Circum-Arctic Permafrost Degradation Observation Using Sentinel-1 InSAR Data

Remote Sensing
In the context of global warming, the accelerated degradation of circum-Arctic permafrost is releasing a significant amount of carbon. InSAR can indirectly reflect the degradation of permafrost by monitoring its deformation.

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 ...

From mammoth to miniature: ‘Model of a summer encampment of the Yakuts’ as a narrative object Du mammouth à la miniature : La maquette de camp d’été des Yakoutes comme objet de narration

Journal of the Royal Anthropological Institute, Volume 32, Issue 1, Page 111-131, March 2026.
Classic anthropological accounts of miniature objects have focused on their spatial and aesthetic dimensions, with more recent work addressing their communicative potential, connections with play, and role in protecting threatened cultural knowledge. This article analyses responses to a miniature landscape model of yhyakh, a festival celebrated in the ...
