TL;DR: In this article, the authors present a review of the changing state of European permafrost within a spatial zone that includes the continuous high latitude arctic permfrost of Svalbard and the discontinuous high altitude mountain permaffrost of Iceland, Fennoscandia and the Alps.

TL;DR: In this article, a review paper examines thermal conditions (active layer and permafrost), internal composition (rock and ice components), kinematics and rheology of creeping perennially frozen slopes in cold mountain areas.

TL;DR: In this article, field data on the rates of solifluction and associated parameters are compiled from the literature, in an attempt to evaluate factors controlling the spatial variability in solificluction processes and landforms.

TL;DR: In this paper, the role of diurnal and annual frost cycles in controlling the timing and magnitude of frost weathering has been discussed in the last five years and several key questions to be answered.

TL;DR: In this paper, the authors investigated rockfall activity during thawing periods by collecting rockfall debris fallen on the snow-covered talus slope in a cirque in the Japanese Alps.
