Ice age

Abstract

The (Quaternary) Ice Age was a period of global cooling of the climate with large areas of glaciation that were approximately three times more extended on the continent than the current terrestrial ice areas. Due to the chronological nearness and the modification of older glacier traces during the Last Glacial, the reliable state of knowledge as to the Last Ice Age is the most extensive, so that the findings of the Würmian glacier extent provide a valid example for the Ice Age glaciation on the whole. The geo-morphological and Quaternary-geological method, that is, the decoding of the arrangements of the positions of landforms (topography) and sediments caused by glacier ice and its dynamics, is the scientific basis of Ice Age reconstruction. The Ice Age climate has been primarily deduced from the reconstructed past glaciation. The climate changes associated with synchronous cold ages in the non-glaciated areas of the earth are also understandable by the secondary global cooling that was strengthened by the feedback of the glaciations.
