The changing thermal state of permafrost
Permafrost temperatures have increased in polar and high-elevation regions, affecting the
climate system and the integrity of natural and built environments. In this Review, we outline …

Tundra vegetation change and impacts on permafrost
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 …

Arctic tundra shrubification: a review of mechanisms and impacts on ecosystem carbon balance
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 …

Future increases in Arctic lightning and fire risk for permafrost carbon
Lightning is an indicator and a driver of climate change. Here, using satellite observations of
lightning flash rate and ERA5 reanalysis, we find that the spatial pattern of summer lightning …

Lake and drained lake basin systems in lowland permafrost regions
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) …

Fast response of cold ice-rich permafrost in northeast Siberia to a warming climate
The ice-and organic-rich permafrost of the northeast Siberian Arctic lowlands (NESAL) has
been projected to remain stable beyond 2100, even under pessimistic climate warming …

Nitrous oxide emissions from permafrost-affected soils
Soils are sources of the potent greenhouse gas nitrous oxide (N2O) globally, but emissions
from permafrost-affected soils have been considered negligible owing to nitrogen (N) …

[HTML][HTML] Climate change and mercury in the Arctic: Abiotic interactions
Dramatic environmental shifts are occuring throughout the Arctic from climate change, with
consequences for the cycling of mercury (Hg). This review summarizes the latest science on …

Reviews and syntheses: Changing ecosystem influences on soil thermal regimes in northern high-latitude permafrost regions
Soils in Arctic and boreal ecosystems store twice as much carbon as the atmosphere, a
portion of which may be released as high-latitude soils warm. Some of the uncertainty in the …
