Science Needs for a Terrestrial Biosphere Tipping Point Early Warning System
Reviews of Geophysics, Volume 64, Issue 4, December 2026.Abstract Tipping points in the Earth system have the potential to cause major detrimental impacts to the biosphere and societies. Their inherent nonlinearity implies that even relatively small additional increases in external forcing might result in disproportionately large adjustments to components of the Earth system.

Biogeochemical Distinctiveness of Peatland Ponds, Thermokarst Waterbodies, and Lakes [PDF]
, 2022 Small lentic freshwater ecosystems play a disproportionate role in global biogeochemical cycles by processing large amounts of carbon (C), nitrogen (N), and phosphorus (P), but it is unlikely that they behave as one homogenous group for the purpose of ...

Thermokarst lakes disturb the permafrost structure and stimulate through-talik formation in the Qinghai–Tibet Plateau, China: a hydrogeophysical investigation [PDF]
The CryosphereThermokarst lakes are widely distributed in the Qinghai–Tibet Plateau (QTP) and continuously disturb the permafrost structure. Investigating the permafrost and sublake talik structures is crucial to assessing and predicting the fate of the ecosystem and ...

Terrestrial inputs and in‐lake processes shape dissolved organic matter along a permafrost gradient
Limnology and Oceanography, Volume 71, Issue 11, November 2026.Abstract Northern permafrost landscapes store large amounts of organic carbon that can enter lakes as dissolved organic matter (DOM), but links among shoreline terrestrial sources, lake‐water DOM composition, and catchment configuration remain uncertain in low‐precipitation Shield landscapes. We combined shoreline soil‐porewater and lake‐water sampling

Active thermokarst zones on permafrost territory and their deteсting on space images
Известия Томского политехнического университета: Инжиниринг георесурсов, 2019 The relevance of the paper is caused by the need to develop methods of identifying and mapping the areas of active thermokarst processes on the permafrost territory, based on satellite images and geoinformation technologies in the context of assessing ...

Journal of Geophysical Research: Biogeosciences, Volume 131, Issue 11, November 2026.Abstract Erosion from ice‐rich permafrost thaw (“thermokarst”) alters tundra vegetation cover and soil moisture, and laterally transports organic material into lakes, altering net fluxes of carbon dioxide (FCO2), methane (FCH4), and nitrous oxide (FN2O).

Thermokarst lake changes over the past 40 years in the Qinghai–Tibet Plateau, China
Frontiers in Environmental Science, 2022 A thermokarst lake is generally defined as a lake that occupies a closed basin and is created by the massive melting of ground ice in ice-rich permafrost regions, which has a great impact on regional hydro-ecological equilibrium and permafrost ...

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
