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 …

Anthropogenic mercury (Hg) emissions have driven marked increases in Arctic Hg levels,
which are now being impacted by regional warming, with uncertain ecological …

It is unequivocal that the increases in atmospheric carbon dioxide (CO2), methane (CH4)
and nitrous oxide (N2O) since the pre-industrial period are caused by human activities. The …

Northern peatlands have accumulated large stocks of organic carbon (C) and nitrogen (N),
but their spatial distribution and vulnerability to climate warming remain uncertain. Here, we …

The Arctic cryosphere is collapsing, posing overlap** environmental risks. In particular,
thawing permafrost threatens to release biological, chemical and radioactive materials that …

Abstract Based on the Baltic Earth Assessment Reports of this thematic issue in Earth
System Dynamics and recent peer-reviewed literature, current knowledge of the effects of …

Where present, permafrost exerts a primary control on water fluxes, flowpaths, and
distribution. Climate warming and related drivers of soil thermal change are expected to …

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) …

Degradation of near-surface permafrost can pose a serious threat to the utilization of natural
resources, and to the sustainable development of Arctic communities. Here we identify at …

Climate warming in regions of ice‐rich permafrost can result in widespread thermokarst
development, which reconfigures the landscape and damages infrastructure. We present …
