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]
Last glacial maximum (LGM), the most recent geologic interval, which spanned 29,000 to 19,000 years ago, in which the geographic extent of ice sheet and glacier coverage on Earth’s surface peaked. Some 8 percent of the planet’s total surface was covered in ice, and sea levels were approximately 125.
The Last Glacial Maximum (LGM), colloquially called the last ice age, was a period in Earth’s history that occurred roughly 26,000 to 19,000 years ago.
The Last Glacial Maximum (LGM) refers to a cold climatic period around 23,000 to 19,000 years ago, characterized by extensive ice-sheets, colder sea surface temperatures, and lower atmospheric CO2 concentration.
The Last Glacial Maximum (LGM) is conventionally defined from sea-level records as the most recent interval in Earth history when global ice sheets reached their maximum integrated volume (1).
The Last Glacial Maximum began when global mean sea level (GMSL) abruptly dropped by about 40 metres around 31,000 years ago 4 and was followed by about 10,000 years of rapid deglaciation...
During the last glacial maximum, the Patagonian ice sheet extended over the Andes from about 35°S to Tierra del Fuego at 55°S. The western part appears to have been very active, with wet basal conditions, while the eastern part was cold-based.
The term “Last Glacial Maximum” is relatively recent and refers to the time of maximum global ice volume inferred from the oxygen isotope stratigraphy (δ 18 O) of ocean sediments (CLIMAP, 1976, 1981).
The Last Glacial Maximum (LGM), one of the best studied palaeoclimatic intervals, offers an excellent opportunity to investigate how the climate system responds to changes in greenhouse gases...
One example is the missing ice problem during the Last Glacial Maximum (LGM, 26 000-19 000 years before present) – an apparent 8-28 m discrepancy between far-field sea level indicators and...
