The
Late Glacial Maximum (c. 13,000-10,000 years ago), or
Tardiglacial ("Late Glacial"), is defined primarily by the beginning of the modern warm period, in which
climates in the
Northern Hemisphere warmed substantially, causing a process of accelerated
deglaciation following the
Last Glacial Maximum (c. 25,000-13,000 years ago). At this time, human populations, previously forced into
refuge areas as a result of Last Glacial Maximum climatic conditions, gradually begin to repopulate the Northern Hemisphere's
Eurasian landmass and eventually
populate North America via
Beringia for the first time.
