Last Glacial Maximum
Climate & environment · Paleoclima · Glaciaciones · Nivel del mar
The Last Glacial Maximum is placed approximately 23,000 to 19,000 years ago. Ice, ocean, and vegetation indicators show a colder Earth with extensive ice sheets; local values and consequences differ among reconstructions, so no identical environmental experience is inferred for all populations.
