Potential carbon emissions dominated by carbon dioxide from thawed permafrost soils

TL;DR: In this paper, a meta-analysis of soil incubation studies from the permafrost zone suggests that thawing under aerobic conditions, which releases CO2, will strengthen the carbon feedback more than waterlogged systems, which release CO2 and CH4.
Journal ArticleDOI

Expert assessment of vulnerability of permafrost carbon to climate change

TL;DR: In this article, the authors used a survey to quantify variability in the perception of the vulnerability of permafrost C to climate change and found that approximately 1700 Pg of soil carbon (C) are stored in the northern circumpolar permafure zone, more than twice as much C than in the atmosphere.
Journal ArticleDOI

Reorganization of vegetation, hydrology and soil carbon after permafrost degradation across heterogeneous boreal landscapes

TL;DR: In this paper, the authors used a chronosequence approach to assess changes in vegetation composition, water storage and soil organic carbon (SOC) stocks along successional gradients within four landscapes: (1) rocky uplands on ice-poor hillside colluvium, (2) silty uplands with extremely ice-rich loess, (3) gravelly-sandy lowlands on eolian sand and (4) peaty-silty lowlands with thick peat deposits over reworked lowland loess.
