Contrasting Responses of Carbon Dioxide and Methane Fluxes Following Thermokarst Erosion Across Tundra‐Lake Interfaces in the Western Canadian Arctic

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).

Advancing Satellite Solar‐Induced Chlorophyll Fluorescence Data Assimilation in Land Surface Models: An Assessment Over Boreal Evergreen Needleleaf Forests

Journal of Advances in Modeling Earth Systems, Volume 18, Issue 11, November 2026.
Abstract Boreal forests represent about 20% of the global forest carbon sink and contribute to climate change mitigation, yet land surface models (LSMs) struggle to simulate their gross primary production (GPP). Space‐borne observations of solar‐induced fluorescence (SIF) have been used to improve LSM GPP through data assimilation.

Role of Ecosystem-Driven Permafrost in Soil Development and Ecosystem Fragmentation During the Holocene Evolution of a Boreal Lowland Landscape

Geosciences
Abandoned floodplains are complex landscapes in boreal permafrost regions due to diverse biogeomorphic effects that are highly modified by permafrost aggradation and degradation.

Petagram‐Scale Dissolved Organic Carbon Stocks in Alaskan Permafrost Soils

Geophysical Research Letters, Volume 53, Issue 20, 28 October 2026.
Abstract The pan‐Arctic permafrost region hosts vast amounts of soil organic carbon, a pool increasingly susceptible to climate‐driven changes. Dissolved organic carbon (DOC) is a key component of this carbon pool. However, its stocks and fluxes remain poorly understood due to limited measurements and challenges of tracking subsurface fluxes across ...

Permafrost thaw and resulting soil moisture changes regulate projected high-latitude CO2 and CH4 emissions

Environmental Research Letters, 2015
The fate of currently frozen permafrost carbon as high-latitude climate warms remains highly uncertain and existing models give widely varying estimates of the permafrost carbon-climate feedback.
