Permafrost Detachment Slides: A Distinct High‐Magnitude Permafrost Mass Wasting Process

Geophysical Research Letters, Volume 53, Issue 18, 28 September 2026.
Abstract Warming permafrost is destabilizing landscapes, intensifying thaw‐driven mass wasting and giving rise to novel landslide forms. We characterize two recent (2017 and 2018), deep‐seated translational failures that we term Permafrost Detachment Slides (PDSs), which rapidly translocated 4.5 and 18 × 106 m3 of frozen material into downstream ...

Evolution of the banks of thermokarst lakes in Central Yakutia (Central Siberia) due to retrogressive thaw slump activity controlled by insolation

, 2015
International audienceAs observed in most regions in the Arctic, the thawing of ice-rich permafrost (thermokarst) has been developing in Central Yakutia.

Proximate Climate Drivers of Beaver Pond Occupancy and Range Expansion in Arctic Alaska

Global Change Biology Communications, Volume 1, Issue 3, September 2026.
To understand why beavers are colonizing the Arctic, we evaluated which climate drivers underpin beaver pond dynamics. Warm Junes, mild winters, green summers, and wet springs facilitate pond establishment. Rapid improvement in these conditions across recent decades provides mechanistic support that climate change is driving beaver colonization of the ...

Role of methanotrophy in a high‐methane emitting thermokarst lake

Limnology and Oceanography, Volume 71, Issue 9, September 2026.
Abstract Thermokarst (thaw) lakes are projected to be an increasing source of atmospheric methane (CH4), a potent greenhouse gas, as climate warms and permafrost thaws. However, the magnitude of CH4 cycling, particularly the role of aerobic CH4 oxidation (methanotrophy), among thermokarst lakes, is not well constrained.

Thermokarst Lakes as a Source of Atmospheric CH4 During the Last Deglaciation

, 2007
Polar ice-core records suggest that an arctic or boreal source was responsible for more than 30% of the large increase in global atmospheric methane (CH4) concentration during deglacial climate warming; however, specific sources of that CH4 are still ...

Shift of thermokarst lakes from methane source to climate-cooling carbon sink

, 2014
Thermokarst lakes formed across vast regions of Siberia and Alaska during the last deglaciation and are thought to be a net source of atmospheric methane and carbon dioxide during the Holocene.

Generalized histogram of lake size-distribution in permafrost of Western Siberia based on satellite images of high resolution

Известия Томского политехнического университета: Инжиниринг георесурсов, 2016
Relevance of the research is caused by the need to clarify the type of law of lakes size-distribution for estimating methane emission from small thermokarst lakes in vast areas of permafrost. Currently, the histograms of the distributions are obtained by

Typical thermokarst alters soil organic carbon fractions controlled by soil water content in the Qinghai–Tibet Plateau

Ecological Indicators
The ongoing climate warming has accelerated permafrost thaw worldwide, resulting in rapid thermokarst development. However, a comprehensive quantification of the responses of soil organic carbon (SOC) fractions to thermokarst development is still lacking.
