High carbon emissions from thermokarst lakes of Western Siberia [PDF]

Nature Communications, 2019
AbstractThe Western Siberia Lowland (WSL), the world’s largest permafrost peatland, is of importance for understanding the high-latitude carbon (C) cycle and its response to climate change. Warming temperatures increase permafrost thaw and production of greenhouse gases.

Elevation‐Dependent Permafrost Thaw on the Tibetan Plateau Delays Seasonal Discharge and Poses a Risk of Reduction in Downstream Water Availability

Earth's Future, Volume 14, Issue 7, July 2026.
Abstract Global warming and permafrost thaw have significantly altered landscapes and hydrological conditions in permafrost regions. While site‐specific process studies have described hydrological changes during thawing, basin‐scale impact assessments and streamflow modeling remain challenging due to landscape heterogeneity and complex interactions ...

Remote sensing of drained thermokarst lake basin successions [PDF]

, 2018
Thermokarst lakes are important factors for permafrost landscape dynamics and carbon cycling. Thermokarst lake cover is particularly high in Arctic lowlands with ice-rich permafrost.

Decadal Shifts Towards Higher Riverine Silicon Relative to Nitrogen and Phosphorus Across High Latitudes

Global Biogeochemical Cycles, Volume 40, Issue 7, July 2026.
Abstract High‐latitude systems are warming faster than the global average, altering the rates of silicon (Si) mobilization from terrestrial to aquatic systems. Dissolved Si (DSi) concentration and its ratio with other nutrients exert strong controls on algae blooms in fresh and marine receiving waters, especially in high‐latitude regions where diatoms ...

Basin evolution and palaeoenvironmental variability of the thermokarst lake El’gene-Kyuele, Arctic Siberia [PDF]

, 2015
Thermokarst lakes are a widespread feature of the Arctic tundra, in which highly dynamic processes are closely connected with current and past climate changes.

Susceptibility Modeling and Potential Risk Analysis of Thermokarst Hazard in Qinghai–Tibet Plateau Permafrost Landscapes Using a New Interpretable Ensemble Learning Method

Atmosphere
Climate change is causing permafrost in the Qinghai–Tibet Plateau to degrade, triggering thermokarst hazards and impacting the environment. Despite their ecological importance, the distribution and risks of thermokarst lakes are not well understood due ...

Research into Cryolithozone Spatial Pattern Changes Based on the Mathematical Morphology of Landscapes

Energies, 2022
Lacustrine thermokarst is receiving great interest as a landscape-forming process. Despite this, research dealing with the quantitative analysis of the changes in the morphological patterns of thermokarst plains under ongoing climate change is lacking ...

Retrogressive Thaw Slump Morphology and Dynamics in Saline Permafrost in Northeast Greenland

Journal of Geophysical Research: Earth Surface, Volume 131, Issue 7, July 2026.
Abstract Saline permafrost occupies a significant portion of permafrost in the Northern Hemisphere and extends several kilometers inland from the present Arctic coastline. However, its thermal conditions, mechanical degradation and geomorphological impacts are poorly understood.
