Rapid Arctic environmental change affects the entire Earth system as thawing permafrost
ecosystems release greenhouse gases to the atmosphere. Understanding how much …

Tundra vegetation productivity and composition are responding rapidly to climatic changes
in the Arctic. These changes can, in turn, mitigate or amplify permafrost thaw. In this Review …

The permafrost zone is expected to be a substantial carbon source to the atmosphere, yet
large-scale models currently only simulate gradual changes in seasonally thawed soil …

Permafrost degradation may induce soil carbon (C) loss, critical for global C cycling, and be
mediated by microbes. Despite larger C stored within the active layer of permafrost regions …

Vegetation composition shifts, and in particular, shrub expansion across the Arctic tundra
are some of the most important and widely observed responses of high-latitude ecosystems …

Abstract Vegetation in Northern Hemisphere, being sensitive to climate change, plays an
important role in the carbon cycles between land and the atmosphere. The response of …

Methane (CH4) is produced in many natural systems that are vulnerable to change under a
warming climate, yet current CH4 budgets, as well as future shifts in CH4 emissions, have …

Life on Earth comes in many forms, but all life-forms share a common element in carbon. It is
the basic building block of biology, and by trap** radiation it also plays an important role …

The formation, growth and drainage of lakes in Arctic and boreal lowland permafrost regions
influence landscape and ecosystem processes. These lake and drained lake basin (L-DLB) …

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 …
