A chronology of climatic events of importance for the Last Glacial Period, about the last 120,000 years The Last Glacial Period caused a much lower global sea level.. The Last Glacial Period (LGP), also known as the Last glacial cycle, occurred from the end of the Last Interglacial to the beginning of the Holocene, c. 115,000 – c. 11,700 years ago, and thus corresponds to most of the ...
During the Last Glacial Maximum, much of the world was cold, dry, and inhospitable, with frequent storms and a dust-laden atmosphere. The dustiness of the atmosphere is a prominent feature in ice cores; dust levels were as much as 20 to 25 times greater than they are in the present.
Lake Tight, named for geologist William G. Tight, was a glacial lake in what is present-day Ohio, Kentucky, and West Virginia, during the Ice Age the early Pleistocene before 700,000 years. [ 1 ] History
Great Famine of 1315–1317 in Europe; Little Ice Age: Various dates between 1250 and 1550 or later are held to mark the start of the Little ice age, ending at equally varied dates around 1850 1460–1550 Spörer Minimum cold; 1656–1715 Maunder Minimum low sunspot activity; 1790–1830 Dalton Minimum low sunspot activity, cold
The colder climate contributed to ice sheet growth in North America, Europe, and Antarctica. At this time there were further major climate shifts around the world. Some areas became too dry to support much life; others housed more vegetation and animals. The northern hemisphere was heavily impacted by ice sheets during the LGM.
A glacial period (alternatively glacial or glaciation) is an interval of time (thousands of years) within an ice age that is marked by colder temperatures and glacier advances. Interglacials, on the other hand, are periods of warmer climate between glacial periods. The Last Glacial Period ended about 15,000 years ago. [1]
A less severe cold period or ice age is shown during the Jurassic-Cretaceous (150 Ma). There have been five or six major ice ages in the history of Earth over the past 3 billion years. The Late Cenozoic Ice Age began 34 million years ago, its latest phase being the Quaternary glaciation, in progress since 2.58 million years ago.
To geologists, an ice age is defined by the presence of large amounts of land-based ice. Prior to the Quaternary glaciation, land-based ice formed during at least four earlier geologic periods: the late Paleozoic (360–260 Ma), Andean-Saharan (450–420 Ma), Cryogenian (720–635 Ma) and Huronian (2,400–2,100 Ma).
