Deglaciation, describes the transition from full glacial conditions during ice ages, to warm interglacials, characterized by global warming and sea level rise due to change in continental ice volume (IPCC AR5). Thus,it refers to the retreat of a glacier, an ice sheet or frozen surface layer, and the resulting exposure of the Earth's surface. The decline of the cryosphere due to ablation can occur on any scale from global to localized to a particular glacier. After the Last Glacial Maximum (ca. 21k years ago), the last deglaciation begun, which lasted until the early Holocene.

In these restricted environments, if they existed at all, humans would have found it difficult to survive until deglaciation was sufficiently advanced to support adequate resources in the form of plants and animals essential to sustain groups of Hunters and gatherers.
But those final 7000 years of deglaciation, particularly the episodes of very rapid and extensive melting, must have been worse.
The rapidity of the deglaciation suggests that some extraordinary factor was affecting the climate.
Nevertheless, it is accepted that precession does have an impact on both glaciation and deglaciation, at widely separated intervals.
