Thermokarst hazards susceptibility mapping on the Qinghai-Tibet plateau based on a collaborative IV-machine learning architecture

Geocarto International
Accelerating climate change intensifies permafrost degradation and thermokarst hazards on the Qinghai-Tibet Plateau (QTP), threatening ecosystems and infrastructure.

Biogeography of Micro-Eukaryotic Communities in Sediment of Thermokarst Lakes Are Jointly Controlled by Spatial, Climatic, and Physicochemical Factors Across the Qinghai-Tibet Plateau

Frontiers in Ecology and Evolution, 2022
Thermokarst lakes are formed following ice-rich permafrost thaw and widely distribute in the cold regions with high latitude and elevation. However, the micro-eukaryotic communities (MECs) in thermokarst lakes are not well studied.

Diminished Radiative Cooling With Northward Wildfire Advance in the East Siberian Boreal Region

Geophysical Research Letters, Volume 53, Issue 19, 16 October 2026.
Abstract Intensification of the Siberian wildfire regime is characterized by large increases in burned area above the Arctic Circle. Wildfire in boreal forests typically reduces albedo in the decades following fire, resulting in a net cooling effect. Here we quantified changes in albedo and the accompanying radiative forcing associated with a northward

Modeled Subsidence of Permafrost Terrain 2025–2050: North‐Central Alaska

Permafrost and Periglacial Processes, Volume 37, Issue 4, Page 692-712, October/December 2026.
ABSTRACT A large fraction of the Alaska terrain is underlain by regolith that contains excess ice (ice that in volume exceeds the natural pore space). Possible loss of excess ice would lead to ground subsidence, which in turn would disturb and destabilize the ground surface.

Thermokarst sedimentology of the Tuktoyaktuk Coastlands, Northwest Territories.

, 1993
Thermokarst sedimentology is the study of the sedimentary processes and facies associated with thermokarst. Using facies analysis, oxygen isotopes and observations of processes in the Tuktoyaktuk Coastlands, this thesis (1) classifies frozen ground ...

Enhanced response of soil respiration to experimental warming upon thermokarst formation [PDF]

International audienceAbstract As global temperatures continue to rise, a key uncertainty of terrestrial carbon (C)–climate feedback is the rate of C loss upon abrupt permafrost thaw.

Impact Assessment And Stochastic Modeling Of Morphometric Parameters Of Thermokarst Hazard For Unpaved Roads

Geography, Environment, Sustainability, 2020
Active construction of new roads and other linear structures requires new techniques for the natural hazard assessment. These techniques can involve both stochastic modeling and remote sensing data (RSD).

Internal Structure, Kinematics, and Prehistory of Frozen Debris Lobe‐A (FDL‐A), Brooks Range, Alaska

Permafrost and Periglacial Processes, Volume 37, Issue 4, Page 645-667, October/December 2026.
ABSTRACT Frozen Debris Lobe‐A (FDL‐A)—one of hundreds of FDLs in the Brooks Range of northern Alaska—is a slow‐moving landslide in permafrost that has been the subject of research since 2008 due to its close proximity to the Dalton Highway. Here, we synthesize more than a decade's worth of climate and surface measurements of monitored FDLs, and the ...

Internal Permafrost Structure of Geomorphologically Distinct Palsas in Northern Sweden Revealed by Quasi‐3D ERT

Permafrost and Periglacial Processes, Volume 37, Issue 4, Page 668-681, October/December 2026.
ABSTRACT Permafrost in northern peatlands occurs within individual palsas or extensive peat plateaus and controls local carbon storage. These permafrost landforms are complex, and their internal structure remains poorly understood. We used quasi‐3D electrical resistivity tomography (ERT) measurements, supported by UAV‐LiDAR topography, frost probing ...
