Rapid atmospheric warming since the mid-twentieth century has increased temperature-
dependent erosion and sediment-transport processes in cold environments, affecting food …

This paper discusses the potential response of fluvial processes and landforms to the
projected permafrost degradation and related hydrological change. Fluvial system structure …

Ice-rich permafrost in the circum-Arctic and sub-Arctic (hereafter pan-Arctic), such as late
Pleistocene Yedoma, are especially prone to degradation due to climate change or human …

Yedoma is a permafrost deposit widely distributed across the Arctic and found exclusively
within the unglaciated regions in northern Siberia, Alaska, and the Yukon, which are the …

One quarter of the Northern hemisphere is underlain by permanently frozen ground, referred
to as permafrost. Due to climate warming, irreversibly thawing permafrost is releasing …

In contrast to the well-recognized permafrost carbon (C) feedback to climate change, the fate
of permafrost nitrogen (N) after thaw is poorly understood. According to mounting evidence …

Arctic warming is causing ancient perennially frozen ground (permafrost) to thaw, resulting
in ground collapse, and reshaping of landscapes. This threatens Arctic peoples' …

Thaw slumps are clear indicators of rapid permafrost degradation. They form preferentially in
near-surface ice-rich permafrost of northern high latitudes after initial thermal disturbance by …

Nitrogen regulates multiple aspects of the permafrost climate feedback, including plant
growth, organic matter decomposition, and the production of the potent greenhouse gas …

The Arctic is nutrient limited, particularly by nitrogen, and is impacted by anthropogenic
global warming which occurs approximately twice as fast compared to the global average …
