Arctic permafrost stores nearly 1,700 billion metric tons of frozen and thawing carbon.
Anthropogenic warming threatens to release an unknown quantity of this carbon to the …

Land degradation continues to be an enormous challenge to human societies, reducing
food security, emitting greenhouse gases and aerosols, driving the loss of biodiversity …

While increasing methane emissions from thawing permafrost are anticipated to be a major
climate feedback, no observational evidence for such an increase has previously been …

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 …

We have constructed an atmospheric inversion framework based on TM5-4DVAR to jointly
assimilate measurements of methane and δ 13 C of methane in order to estimate source …

Abstract Purpose of Review The Arctic has experienced the most rapid change in climate of
anywhere on Earth, and these changes are certain to drive changes in the carbon budget of …

Soils form the skin of the Earth's surface, regulating water and biogeochemical cycles and
generating production of food, timber, and textiles around the world. Changes in soil and its …

We estimate the causal contributions of spatiotemporal changes in temperature (T) and
precipitation (Pr) to changes in Earth's atmospheric methane concentration (C CH4) and its …

Methane (CH4) emissions from the boreal and arctic region are globally significant and
highly sensitive to climate change. There is currently a wide range in estimates of high …

Rapid warming in the Arctic has a huge impact on the global environment. Atmospheric
brown carbon (BrC) is one of the least understood and uncertain warming agents due to a …
