The interchange between permafrost degradation and aggradation shapes sub-Arctic and Arctic lowland landscapes, and therefore contain records of past climate and landscape development. [ 20 ] Pingos are vulnerable to surface disturbance given the considerable amount of ground ice stored within them.

Also known as Arctic bases, polar stations or ice stations, these bases are widely distributed across the northern polar region of Earth. Historically few research stations have been permanent.

[189] However, if the warming continues under RCP8.5, then permafrost emissions of mercury into the atmosphere would match the current global emissions from all human activities by ...
Within the Holarctic realm, there are a variety of ecosystems. The type of ecosystem found in a given area depends on its latitude and the local geography. In the far north, a band of Arctic tundra encircles the shore of the Arctic Ocean. The ground beneath this land is permafrost (frozen year-round). In these difficult growing conditions, few ...
Ice segregation is the geological phenomenon produced by the formation of ice lenses, which induce erosion when moisture, diffused within soil or rock, accumulates in a localized zone. The ice initially accumulates within small collocated pores or pre-existing cracks, and, as long as the conditions remain favorable, continues to collect in the ...
