From Wikipedia, the free encyclopedia
Quaternary glaciation also known as the Pleistocene glaciation or the current ice age, refers to a series of glacial events separated by interglacial events during the Quaternary period from 2.58 Ma (million years ago) to present.[1] During this period, ice sheets were established in Antarctica and perhaps Greenland, and fluctuating ice sheets occurred elsewhere (for example, the Laurentide ice sheet). The major effects of the ice age are erosion and deposition of material over large parts of the continents, modification of river systems, creation of millions of lakes, changes in sea level, development of pluvial lakes far from the ice margins, isostatic adjustment of the crust, and abnormal winds. It affects oceans, flooding, and biological communities. The ice sheets themselves, by raising the albedo, effect a major feedback on climate cooling.

- "Last ice age" redirects here. The term "Last ice age" can be confused with the last glacial period of the Quaternary glaciation. The "last glacial period" is the most recent of many advances and retreats of glaciation. Quaternary glaciation deals with many topics, one of which is current climate conditions based on non-human long term glacial causes and effects. For human activities related to climate see Global warming.
