The Earth is currently in such an interglacial period of the Quaternary glaciation, with the Last Glacial Period of the Quaternary having ended approximately 11,700 years ago. The current interglacial is known as the Holocene epoch. [1] Based on climate proxies, paleoclimatologists study the different climate states originating from glaciation.
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 ...
The timeline of glaciation covers ice ages specifically, which tend to have their own names for phases, often with different names used for different parts of the world. The names for earlier periods and events come from geology and paleontology. The marine isotope stages (MIS) are often used to express dating within the Quaternary.
In West Asia, especially Mesopotamia, the 8.2-kiloyear event was a 300-year aridification and cooling episode which may have provided the natural force for Mesopotamian irrigation agriculture and surplus production, which were essential for the earliest formation of classes and urban life. [citation needed] However, changes taking place over ...

The Late Pleistocene is an unofficial age in the international geologic timescale in chronostratigraphy , also known as the Upper Pleistocene from a stratigraphic perspective.
The Mid-Pleistocene Transition (MPT), also known as the Mid-Pleistocene Revolution (MPR), [1] is a fundamental change in the behaviour of glacial cycles during the Quaternary glaciations. [2] [3] The transition lasted around 550,000 years, [4] from 1.25 million years ago until 0.7 million years ago approximately, in the Pleistocene epoch. [5]
The Sangamonian Stage (or Sangamon interglacial) is the term used in North America to designate the Last Interglacial (130,000-115,000 years ago) and depending on definition, part of the early Last Glacial Period, corresponding to Marine Isotope Stage 5 (~130-80,000 years ago).
