  • Record 2024 winter carbon emissions coincide with record warmth across boreal forest, tundra, and wetland ecosystems

    Open AccessGrant Falvo, Edward A G Schuur et al.ARTICLEEnvironmental Research Letters2025

    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 winter (September–April) documented as having the warmest land surface air temperatures on record for the Arctic region. However, corresponding impacts on ecosystem greenhouse gas fluxes typically take several y…

  • Slow post-fire carbon balance recovery despite increased net uptake rates in Alaskan tundra

    Open AccessJacqueline K Y Hung, Kyle A Arndt et al.ARTICLEEnvironmental Research Letters2024

    Increasing wildfire occurrence and intensity have immediate effects on northern ecosystems due to combustion of aboveground vegetation and belowground soil organic matter. These immediate impacts have indirect and longer term effects, including deepening of the active layer, changes in soil decomposition rates, and shifts in plant community composition. Despite the increasing fire impacts across the tundra region, the implications of wildfire on …

  • Soil respiration strongly offsets carbon uptake in Alaska and Northwest Canada

    Open AccessJennifer D Watts, Susan M Natali et al.ARTICLEEnvironmental Research Letters2021

    Soil respiration (i.e. from soils and roots) provides one of the largest global fluxes of carbon dioxide (CO 2 ) to the atmosphere and is likely to increase with warming, yet the magnitude of soil respiration from rapidly thawing Arctic-boreal regions is not well understood. To address this knowledge gap, we first compiled a new CO 2 flux database for permafrost-affected tundra and boreal ecosystems in Alaska and Northwest Canada. We then used th…

  • Seasonality buffers carbon budget variability across heterogeneous landscapes in Alaskan Arctic Tundra

    Open AccessJosh Hashemi, Donatella Zona et al.ARTICLEEnvironmental Research Letters2021

    Arctic tundra exhibits large landscape heterogeneity in microtopography, hydrology, and active layer depth. While many carbon flux measurements and experiments are done at or below the mesoscale (1 km), modern ecosystem carbon modeling is often done at scales of 0.25 -1.0 latitude, creating a mismatch between processes, process input data, and verification data. Here we arrange the naturally complex terrain into mesoscale landscape types of varyi…

  • Arctic greening associated with lengthening growing seasons in Northern Alaska

    Open AccessKyle A Arndt, Maria J Santos et al.ARTICLEEnvironmental Research Letters2019

    Many studies have reported that the Arctic is greening; however, we lack an understanding of the detailed patterns and processes that are leading to this observed greening. The normalized difference vegetation index (NDVI) is used to quantify greening, which has had largely positive trends over the last few decades using low spatial resolution satellite imagery such as AVHRR or MODIS over the pan-Arctic region. However, substantial fine scale spa…
