  • 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…

  • The biophysical climate mitigation potential of boreal peatlands during the growing season

    Open AccessManuel Helbig, J M Waddington et al.ARTICLEEnvironmental Research Letters2020

    Peatlands and forests cover large areas of the boreal biome and are critical for global climate regulation. They also regulate regional climate through heat and water vapour exchange with the atmosphere. Understanding how land-atmosphere interactions in peatlands differ from forests may therefore be crucial for modelling boreal climate system dynamics and for assessing climate benefits of peatland conservation and restoration. To assess the bioph…

  • Prompt active restoration of peatlands substantially reduces climate impact

    Open AccessKelly A Nugent, Ian B Strachan et al.ARTICLEEnvironmental Research Letters2019

    Restoration of peatlands after peat extraction could be a benefit to the climate system. However a multi-year ecosystem-scale assessment of net carbon (C) sequestration is needed. We investigate the climate impact of active peatland restoration (rewetting and revegetating) using a chronosequence of C gas exchange measurements across post-extraction Canadian peatlands. An atmospheric perturbation model computed the instantaneous change in radiativ…

  • Warmer spring conditions increase annual methane emissions from a boreal peat landscape with sporadic permafrost

    Open AccessManuel Helbig, William L Quinton et al.ARTICLEEnvironmental Research Letters2017

    About a fifth of the global wetland methane emissions originate from boreal peatlands, which represent an important land cover type in boreal landscapes in the sporadic permafrost zone. There, rising air temperatures could lead to warmer spring and longer growing seasons, changing landscape methane emissions. To quantify the effect of warmer spring conditions on methane emissions of a boreal peat landscape in the sporadic permafrost zone of north…
