Reviews and syntheses: Changing ecosystem influences on soil thermal regimes in northern high-latitude permafrost regions
Abstract. Permafrost soils in arctic and boreal ecosystems store twice the amount of current atmospheric carbon that may be mobilized and released to the atmosphere as greenhouse gases when soils thaw under a warming climate. This permafrost carbon climate feedback is among the most globally importa...
