The Pleistocene epoch is the period of geologic time from approximately 1.8 million years ago to 10,000 years ago. The Pleistocene is most noted for the tremendous shifts in climate as a result of periodic glacial (cold) and interglacial (warm) conditions. Of primary interest to environmental science is the latest Pleistocene, which is from 20,000 years before present to the beginning of the Holocene at 10,000 years ago. The latest Pleistocene is of interest because that was a time when the great melting of the Pleistocene ice sheets occurred and sea level rose rapidly. Near the end of the Pleistocene, about 11,000 years before present, a minor cooler period known as the Younger Dryas occurred and this was followed by rapid warming into the ...
