Streams and rivers can substantially modify organic carbon (OC) inputs from terrestrial
landscapes, and much of this processing is the result of microbial respiration. While carbon …

The Earth is warming, especially in polar areas in which winter temperatures and
precipitation are expected to increase. Despite a growing research focus on winter climatic …

Arctic wetlands are known methane (CH4) emitters but recent studies suggest that the Arctic
CH4 sink strength may be underestimated. Here we explore the capacity of well-drained …

Methane (CH 4) emissions from the northern high‐latitude region represent potentially
significant biogeochemical feedbacks to the climate system. We compiled a database of …

Quantifying changes in thermokarst lake extent is of importance for understanding the
permafrost‐related carbon budget, including the potential release of carbon via lake …

Climate change and associated Arctic amplification cause a degradation of permafrost
which in turn has major implications for the environment. The potential turnover of frozen …

Landscape drying associated with permafrost thaw is expected to enhance microbial
methane oxidation in arctic soils. Here we show that ice-rich, Yedoma permafrost deposits …

Methane (CH4) emissions from pan-Arctic wetlands provide a potential positive feedback to
global warming. However, the differences in CH4 emissions across wetland types in these …

Permafrost peatlands are biogeochemical hot spots in the Arctic as they store vast amounts
of carbon. Permafrost thaw could release part of these long‐term immobile carbon stocks as …

Arctic tundra soils serve as potentially important but poorly understood sinks of atmospheric
methane (CH4), a powerful greenhouse gas,,,,. Numerical simulations project a net increase …
