Rock‐wall temperatures in the Alps: modelling their topographic distribution and regional differences
Abstract Rising temperatures or the complete thaw of permafrost in rock walls can affect their stability. Present as well as projected future atmospheric warming results in permafrost degradation and, as a consequence, makes knowledge of the spatial distribution and the temporal evolution of rock te...
