The issue of permafrost and glaciers relationship has not yet been resolved. W. Dobiński’s article takes up this issue again, pointing to the basic criterion that differentiates glaciology and permafrost science, which is ice and freezing. Permafrost is the physical state of the lithosphere, while ice has a material expression, it is a rock. Ice, wherever it accumulates for more than two years, fulfills the definition of permafrost because it can be classified as soil or rock that remains at a temperature equal to or lower than 0 ° C for at least two consecutive years. The author bases the inference from the tradition of cryospheric research, showing the occurrence of the above relationships in snow, ice with different thermics and rock glaciers. Indicates the possibility of distinguishing characteristic thermal boundaries (e.g. active layer) in both periglacial and glacial environments.
