 Wikipedia: Ice age
An ice age is a period of long-term downturn in the temperature of Earth's climate, resulting in an expansion of the polar ice caps and mountain glaciers ("glaciation").
The idea that, in the past, glaciers had been far more extensive was folk knowledge in some alpine regions of Europe (Imbrie and Imbrie, p25, quote a woodcutter telling de Charpentier of the former extent of the Swiss Grimsel glacier).
The end of the last glaciation also corresponds quite closely to the development of permanent human settlements and agriculture, and it is possible that there is a connection between the two events.

 Devensian Glaciation
During the glacial maximum in Scandinavia, only the western parts of Jutland (a part of Denmark) were ice-free during the glaciation and a large part of what is today the North Sea was dry land connecting Jutland with Britain.
This glaciation is made of three glacial maximums (commonly called ice age s) separated by interglacial periods (such as the one we are living in).
During the height of Würm glaciation, ''ca'' 24,000–10,000 ybp, most of western and central Europe and Eurasia was open steppe-tundra, while the Alps presented solid ice field s and montane glaciers, while Scandinavia and much of Britain were under ice.

In between periods of glaciation, there are multi-million year periods of more temperate climate, but also within these abovementioned periods (or at least within the last one), temperate and severe periods occur.
The Great Lakes were carved out of the Canadian Shield by ice, Long Island was formed from glacial till, and the watersheds of Canada were so severely disrupted that they are still sorting themselves out -- the plethora of lakes in northern Canada can be almost entirely attributed to the action of the ice.
The theory of ice ages was first published by Louis Agassiz in his book Étude sur les glaciers of 1840 and was based on observations made in Switzerland.

As the climate warmed, the glaciers retreated, the ice melted, and the sea-level rose.
At certain times during this glaciation, enough water was locked up in the form of ice sheets to cause a drop in sea level and the creation of a land bridge between Siberia and Alaska.
The Würm glacial stage followed the Riss-Würm interglacial and is correlated with the Weichsel glacial stage of northern Europe and the Wisconsin glacial stage of North America.

The cold phases during the last glacial correspond with the maximum extent of glaciers, the maximum periglacial activity on the slopes, and the accumulation of huge alluvial fans (bajadas) in the foreland of the mountains.
The dust supply in this area was high during the Glacial periods of the Quaternary, although it is the presence of a dust-trapping vegetation cover that controls the development of an aeolian cover at the end of the Glacial period and during the Holocene.

Melt water released from the glacial mass carries loads of material eroded by the ice and this material is deposited in the proglacial area.
The extensive and complex Saale deposits are correlated with the Wolstonian (or Gipping) glacial stage of Britain and the Riss glacial stage of the European Alpine region.
The Drente and Warthe represent periods of glacial advance, or maxima, whereas the Treene represents an interstadial period of glacial retreat between the early Drente and the late Warthe.

There has been some fear of a new glacial starting, but the recent global warming has erased those, and the opposite is more feared now.
The complex pattern of changes in Earth orbit and the change of albedo dictate the occurrence of glacial and interglacial phases - this was first explained by the theory of Milutin Milankovic which is confirmed by the recently discovered details about the last ice age.

Since the typical interglacial lasts ~12,000 years, there has been some fear of a new glacial starting, but the recent global warming has erased those, and the opposite is more feared now.
While Milankovic forcing predicts that cyclic changes in the Earth's orbital parameters can be expressed in the glaciation record, additional explanations are neccesary to explain which cycles are observed to be most important in the timing of glacial periods.
In particular, during the last 800 thousand years the dominant glacial oscillation has been 100 thousand, which corresponds to changes in Earth's eccentrity and inclination, and yet is by far the weakest of the three frequencies predicted by Milankovic.

The North German Lowlands were formed during the Pleistocene period by glaciers from different glaciation periods, just as this was the case in Canada and northern parts of the United States.
Especially the eastern parts of Schleswig-Holstein and the northern parts of Mecklenburg Western-Pomerania were covered by the latest advance of the ice during the Weichsel glaciation period (corrensponds to the Wisconsin ice age in North America).
Another glacial feature is the many lakes of Schleswig-Holstein and of Mecklenburg which represent an important natural resource for the development of tourism in these regions.

The basic contours of the Danish landscape were shaped at the end of the Pleistocene Epoch by the last glaciation of the Ice Age, the so-called Weichsel glaciation.
This great glacial mass withdrew temporarily during several warmer interstadial periods, but it repeatedly returned to cover the land until it retreated to the Arctic north for the last time about 10,000 years ago.
As a result, the barren layers of chalk and limestone that earlier constituted the land surface acquired a covering of soil that built up as the Weichsel retreated, forming low, hilly moraines that diversify the otherwise flat landscape.

The lithostratigraphic position of the track horizon is in the lowermost »periglaziale Lößaue« (periglacial loess floodplain) unit which belongs to the Weichsel glaciation.
Based on the mammal remains from the older and younger »Niederterrasse« (alluvial plain) of the Emscher river, the »Knochenkies« (bone gravel) unit is determined to be of early to middle Weichselian age.
The track horizon at the base of the periglacial loess floodplain therefore is of late middle Weichselian age which is in agreement with the luminescence dating.

 Chronodynamics of the Labe river antecedence
Changing climate-morphogenetical processes, alternating between semiarid very cold glacial and humid, mildly warm interglacial periods led, together with tectonic uplifts, to a progressive deepening of the Labe and of its affluents and to the present-day canyon valleys development.
The sediments of this terrace are assigned both to the second Elster glaciation and to the cold oscillation of the Elster-Saale interglacial (Šibrava 1972).
According to Šibrava's interpretation (1972), the nearly 30 m thick accumulation of the IIIrd terrace was due to the Labe blocking by the continental glacier in the region of Meissen in the Menap and in the first stage of the Elster (Mindel).

During the period of early Weichsel Glaciation "Dansgaard-Oeschger Oscillations" and "Heinrich Events" dominated the climatic variability above all oceans of the northern hemisphere.
According to these the movements of inland glaciers during the Weichsel Glaciation went along with immense neotectonic movements in the upper crust (activated by ice-isostatic forces).
The main focus of the planned examinations is put on the reconstruction of variations which took place during Holocene and Glaciation within the variability of the pacific El Nino.

 Introduction   (Site not responding. Last check: 2007-10-09)
Although geologists have termed the time since the end of the last great ice age the Holocene, it really belongs to the Pleistocene, since there were warmer periods that lasted much longer than the present one even in the middle of the Pleistocene.
Whatever epoch you choose to envision us in, the great warming that ended the Wisconsin/Wurm/Weichsel Glaciation had enormous implications for the development and spread of humanity on this planet.
This assignment will briefly review the physical events of the end of the last great glacial period.

Most paleoecological studies focus on the Quaternary sub-era (the last 2 million years) because older environments are less well represented in the fossil record.
Most concentrate on the Holocene epoch (the last 10,000 years), or the last glacial period of the Pleistocene epoch (the Wisconsin/Weichsel/Devensian/Wurm glaciation of the ice age, from 50,000 to 10,000 years ago).
These studies are useful for understanding the dynamics of ecosystem change and for reconstructing pre-industrialization ecosystems.
