  • Reflections and projections on a decade of climate science

    Open AccessVeronika Eyring, Vimal Mishra et al.ARTICLENature Climate Change2021

  • Mapping and understanding the vulnerability of northern peatlands to permafrost thaw at scales relevant to community adaptation planning

    Open AccessCarolyn Gibson, Carolyn M Gibson et al.ARTICLEEnvironmental Research Letters2021

    Developing spatially explicit permafrost datasets and climate assessments at scales relevant to northern communities is increasingly important as land users and decision makers incorporate changing permafrost conditions in community and adaptation planning. This need is particularly strong within the discontinuous permafrost zone of the Northwest Territories (NWT) Canada where permafrost peatlands are undergoing rapid thaw due to a warming climat…

  • Identifying increasing risks of hazards for northern land-users caused by permafrost thaw

    Open AccessCarolyn Gibson, Carolyn M Gibson et al.ARTICLEEnvironmental Research Letters2021

    Understanding the causes and consequences of environmental change is one of the key challenges facing researchers today as both types of information are required for decision making and adaptation planning. This need is particularly poignant in high latitude regions where permafrost thaw is causing widespread changes to local environments and the land-users who must adapt to changing conditions to sustain their livelihoods. The inextricable link …

  • Focus on changing fire regimes

    Open AccessBrendan M Rogers, Jennifer K Balch et al.ARTICLEEnvironmental Research Letters2020

    Fire is a complex Earth system phenomenon that fundamentally affects vegetation distributions, biogeochemical cycling, climate, and human society across most of Earth’s land surface. Fire regimes are currently changing due to multiple interacting global change drivers, most notably climate change, land use, and direct human influences via ignition and suppression. It is therefore critical to better understand the drivers, patterns, and impacts of…

  • Controls on boreal peat combustion and resulting emissions of carbon and mercury

    Open AccessAndrew J Kohlenberg, Merritt R Turetsky et al.ARTICLEEnvironmental Research Letters2017

    Warming in the boreal forest region has already led to changes in the fire regime. This may result in increasing fire frequency or severity in peatlands, which could cause these ecosystems to shift from a net sink of carbon (C) to a net source of C to the atmosphere. Similar to C cycling, peatlands serve as a net sink for mercury (Hg), which binds strongly to organic matter and accumulates in peat over time. This stored Hg is also susceptible to …

  • Influence of Holocene permafrost aggradation and thaw on the paleoecology and carbon storage of a peatland complex in northwestern Canada

    Open AccessNicolas Pelletier, Julie Talbot et al.ARTICLEThe Holocene2017Citada por: 4Referências: 4

    Permafrost in peatlands strongly influences ecosystem characteristics, including vegetation composition, hydrological functions, and carbon cycling. Large amounts of organic carbon are stored in permafrost peatlands in northwestern Canada. Their possible degradation into permafrost-free wetlands including thermokarst bogs may affect carbon (C) stocks, but the direction and magnitude of change are uncertain. Using peat core reconstructions, we cha…

  • More frequent burning increases vulnerability of Alaskan boreal black spruce forests

    Open AccessElizabeth Hoy, Merritt R Turetsky et al.ARTICLEEnvironmental Research Letters2016

    Much recent research has investigated the effects of burning on mature black spruce ( Picea mariana ) forests in interior Alaska, however little research has focused on how frequent reburning affects soil organic layer (SOL) vulnerability in these ecosystems. We compared organic soil layer characteristics in black spruce stands that burned after two fire-free intervals (FFI), including an intermediate-interval (37–52 years) and a more typical lon…

  • Biomass offsets little or none of permafrost carbon release from soils, streams, and wildfire

    Open AccessBenjamin W Abbott, Jeremy B Jones et al.ARTICLEEnvironmental Research Letters2016

    As the permafrost region warms, its large organic carbon pool will be increasingly vulnerable to decomposition, combustion, and hydrologic export. Models predict that some portion of this release will be offset by increased production of Arctic and boreal biomass; however, the lack of robust estimates of net carbon balance increases the risk of further overshooting international emissions targets. Precise empirical or model-based assessments of t…

  • Global vulnerability of peatlands to fire and carbon loss

  • Influence of the permafrost boundary on dissolved organic matter characteristics in rivers within the Boreal and Taiga plains of western Canada

    Open AccessDavid Olefeldt, Anders Persson et al.ARTICLEEnvironmental Research Letters2014

    Catchment export of terrestrial dissolved organic matter (DOM) and its downstream degradation in aquatic ecosystems are important components of landscape scale carbon balances. In order to assess the influence of peatland permafrost on river DOM characteristics, we sampled 65 rivers along a 900 km transect crossing into the southern discontinuous permafrost zone on the Boreal and Tundra Plains of western Canada. Catchment peatland cover and catch…

  • A database and synthesis of northern peatland soil properties and Holocene carbon and nitrogen accumulation

    Open AccessJulie Loisel, Zicheng Yu et al.ARTICLEThe Holocene2014Citada por: 21Referências: 11

    Here, we present results from the most comprehensive compilation of Holocene peat soil properties with associated carbon and nitrogen accumulation rates for northern peatlands. Our database consists of 268 peat cores from 215 sites located north of 45°N. It encompasses regions within which peat carbon data have only recently become available, such as the West Siberia Lowlands, the Hudson Bay Lowlands, Kamchatka in Far East Russia, and the Tibetan…

  • Controls on ecosystem and root respiration across a permafrost and wetland gradient in interior Alaska

    Open AccessNicole A McConnell, Merritt R Turetsky et al.ARTICLEEnvironmental Research Letters2013

    Permafrost is common to many northern wetlands given the insulation of thick organic soil layers, although soil saturation in wetlands can lead to warmer soils and increased thaw depth. We analyzed five years of soil CO 2 fluxes along a wetland gradient that varied in permafrost and soil moisture conditions. We predicted that communities with permafrost would have reduced ecosystem respiration (ER) but greater temperature sensitivity than communi…

  • Modeling the effects of fire severity and climate warming on active layer thickness and soil carbon storage of black spruce forests across the landscape in interior Alaska

    Open AccessHélène Genet, A D McGuire et al.ARTICLEEnvironmental Research Letters2013

    There is a substantial amount of carbon stored in the permafrost soils of boreal forest ecosystems, where it is currently protected from decomposition. The surface organic horizons insulate the deeper soil from variations in atmospheric temperature. The removal of these insulating horizons through consumption by fire increases the vulnerability of permafrost to thaw, and the carbon stored in permafrost to decomposition. In this study we ask how w…
