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.
During the last 3 Ma, ice sheets have also developed on the northern hemisphere. That phase is known as the Quaternary glaciation , and was marked by more or less extensive glaciation. They first appeared with a dominant frequency of 41,000 years, but after the Mid-Pleistocene Transition that changed to high-amplitude cycles, with an average ...
However, there is debate as to whether it is actually a separate epoch or merely an interglacial period within the Pleistocene epoch. [2] [3] Between 9,000 and 5,000 years ago there was a warm period called the Holocene climatic optimum. Being in an interglacial, there is less ice than there was during the last glacial period.

The Meltwater pulse 1A event coincides with or closely follows the abrupt onset of the Bølling–Allerød (BA), when global sea level rose about 16 m during this event at rates of 26–53 mm/yr. [26] In the Great Barrier Reef, the Bølling–Allerød period is associated with a substantial accumulation of calcium carbonate, which is consistent ...

The Holocene Epoch began approximately 11,700 calendar years before present [10] and continues to the present. During the Holocene , continental motions have been less than a kilometer. The last glacial period of the current ice age ended about 10,000 years ago. [ 54 ]
