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…

Permafrost–wildfire interactions: active layer thickness estimates for paired burned and unburned sites in northern high latitudes Open
As the northern high-latitude permafrost zone experiences accelerated warming, permafrost has become vulnerable to widespread thaw. Simultaneously, wildfire activity across northern boreal forest and Arctic/subarctic tundra regions impacts…

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…

Fusing Regional and Global Datasets to Develop a Composite Land Cover Product Across High Latitudes Open
Rapid warming across the Arctic is the primary driver of widespread permafrost thaw, with far-reaching consequences for local ecosystem resilience, the regional carbon budget, and the global climate system. Because permafrost characteristi…

Modeling Thermal and Biogeochemical Dynamics in Two Ponds Within Alaska's Yukon–Kuskokwim Delta: Impacts of Climatic Variability on Greenhouse Gas Fluxes Open
Fluxes of carbon dioxide (CO 2 ) and methane (CH 4 ) from open water bodies are critical components of carbon‐climate feedbacks in high latitudes. Processes governing the spatial and temporal variability of these aquatic greenhouse gas (GH…

Regional Hotspots of Change in Northern High Latitudes Informed by Observations From Space Open
The high latitudes cover ∼20% of Earth's land surface. This region is facing many shifts in thermal, moisture and vegetation properties, driven by climate warming. Here we leverage remote sensing and climate reanalysis records to improve u…
