Abstract Changes are projected for the boreal biome with complex and variable effects on forest vegetation including drought‐induced tree mortality and forest loss. With soil and atmospheric conditions governing drought intensity, specific drivers

Estimates of winter (snow-covered non-growing season) CO2 fluxes across the Arctic region vary by a factor of three and a half, with considerable variation between measured and simulated fluxes. Measurements of snow properties, soil temperatures and

Arctic warming is affecting snow cover and soil hydrology, with consequences for carbon sequestration in tundra ecosystems. The scarcity of observations in the Arctic has limited our understanding of the impact of covarying environmental drivers on t

Effects of Warming and Permafrost Thaw on Carbon Dioxide Fluxes from Boreal Peatlands in northwestern Canada

Autor: Gabriel Hould Gosselin, Laura Chasmer, Oliver Sonnentag, Chris Hopkinson, Manuel Helbig, Natascha Kljun, Christopher Schulze, David Olefeldt

The Taiga Plains ecozone in northwestern Canada is warming rapidly which alters the carbon dioxide (CO2) fluxes of the boreal peat landscape in two ways: 1) directly by increasing temperatures going along with increasing fluxes and 2) indirectly via
