Record 2024 winter carbon emissions coincide with record warmth across boreal forest, tundra, and wetland ecosystems Open
The warming Arctic could accelerate climate change as permafrost soil carbon is released as greenhouse gas emissions from boreal forest, tundra, and wetland ecosystems. Record climate conditions are increasingly common, with the 2023–2024 …

A Review of Abrupt Permafrost Thaw: Definitions, Usage, and a Proposed Conceptual Framework Open
Purpose of Review We review how ‘abrupt thaw’ has been used in published studies, compare these definitions to abrupt processes in other Earth science disciplines, and provide a definitive framework for how abrupt thaw should be used in th…

WetCH <sub>4</sub> : a machine-learning-based upscaling of methane fluxes of northern wetlands during 2016–2022 Open
Wetlands are the largest natural source of methane (CH4) emissions globally. Northern wetlands (>45° N), accounting for 42 % of global wetland area, are increasingly vulnerable to carbon loss, especially as CH4 emissions may accelerate und…

Permafrost, Peatland, and Cropland Regions Are Key to Reconciling North American Carbon Sink Estimates Open
Persistent discrepancies between bottom‐up, terrestrial biosphere models (TBMs), and top‐down, atmospheric inversions, have made it difficult to quantify the magnitude of the North American terrestrial carbon sink. Previous studies have co…
