The neoglaciation is the Earth’s climatic phase characterized by rebirth and/or growth of glaciers associated with a readvance of ice sheets between the postglacial phase and the present. It basically describes the cooling trend in the Earth’s climate during the Holocene period. It has no well marked beginning but a period of general expansion of glaciers variously defined approximately as spanning from 3,000 to 2,000 years ago or covering the last 4,000–5,000 years.
The neoglaciation period was the return of cool moist condition from the warming of Holocene period. The cooling was accompanied by increased precipitation and moisture which helped in the renovation of the glaciers that had not existed since the last ice age.
Neoglaciation is also said to have started with the fluctuations of ice field in response to the climatic oscillations of the little ice age cycle. The most severe part of the neoglacial period seems to have been at its end, in the Little Ice Age. The neoglacial...
