A stunning new study delves into the depths of the increase in rainfall seen in Greenland the global implications it has sheets for melting the massive ice sheets especially during winter time. An ice sheet is also known as a continental glacier. The current ice age define known as the Pliocene- Quaternary glaciation started about 2. 58 million years ago during the late Pliocene, when the spread of ice sheets in the Northern Hemisphere began. During the last glacial period the Laurentide ice sheet covered define much of Canada the Weichselian ice sheet covered Northern Europe, North America, the Patagonian ice sheet covered much of Southern South define America. In the last report by the IPCC ( Intergovernmental define Panel on Climate Change), the development of the ice sheets was regarded as the major unknown factor with regard to predicting future sea level rises.

Ice motion is dominated by the movement of glaciers, whose gravity - driven activity is controlled by two main variable factors: the temperature and strength of their bases.
