The Last Glacial Maximum (LGM), also referred to as the Last Glacial Coldest Period, [1] was the most recent time during the Last Glacial Period where ice sheets were at their greatest extent 26,000 and 20,000 years ago. [2] Ice sheets covered much of Northern North America, Northern Europe, and Asia and profoundly affected Earth 's climate by ...
An artist's impression of the last glacial period at glacial maximum [4]. The LGP is often colloquially referred to as the "last ice age", though the term ice age is not strictly defined, and on a longer geological perspective, the last few million years could be termed a single ice age given the continual presence of ice sheets near both poles.
The Pleistocene (/ ˈplaɪstəˌsiːn, - stoʊ -/ PLY-stə-seen, -stoh-; [ 5 ][ 6 ] often referred to colloquially as the Ice Age) is the geological epoch that lasted from c.2.58 million to 11,700 years ago, spanning the Earth's most recent period of repeated glaciations. Before a change was finally confirmed in 2009 by the International ...
The Last Glacial Maximum map with vegetation types. Last Glacial Maximum refugia were places (refugia) in which humans and other species survived during the Last Glacial Period, around 25,000 to 18,000 years ago. [1] Glacial refugia are areas that climate changes were not as severe, and where species could recolonize after deglaciation.
Laurentide ice sheet. The maximum extent of glacial ice in the north polar area during the Pleistocene period included the vast Laurentide ice sheet in eastern North America. The Laurentide ice sheet was a massive sheet of ice that covered millions of square miles, including most of Canada and a large portion of the Northern United States ...
Blue: The extent in earlier ice ages. The Würm glaciation or Würm stage (German: Würm-Kaltzeit or Würm-Glazial, colloquially often also Würmeiszeit or Würmzeit; cf. ice age), usually referred to in the literature as the Würm[1] (often spelled "Wurm"), was the last glacial period in the Alpine region. It is the youngest of the major ...
Map showing the extent of the Patagonian Ice Sheet in the Strait of Magellan area during the last glacial period. Selected modern settlements are shown with yellow dots. Sea level was much lower than shown here. During the last ice age the Patagonian Ice Sheet created the elongated and forested drumlins seen south of Puerto Williams, Chile.
As such, the last time the comet came so close to the sun and Earth was during the last Ice Age, when humans and Neanderthals existed on the planet at the same time. It was reported in the ...
