The Last Interglacial was the interglacial period that began about 130,000 years ago at the end of the Penultimate Glacial Period, and ended about 115,000 years ago at the beginning of the Last Glacial Period. It corresponds to Marine Isotope Stage 5e. It was the second-to-latest interglacial of the current Ice Age, the most recent being the Holocene which extends to the present day (having followed the Last Glacial Period). During the Last Interglacial, the proportion of CO2 in the atmosphere was about 280 parts per million. The Last Interglacial was one of the warmest periods of the last 800,000 years, with temperatures comparable to and at times warmer (by up to on average 2 degrees Celsius) than the contemporary Holocene interglacial, with the maximum sea level being up to 6 to 9 metres higher than at present, with global ice volume likely also being smaller than the Holocene interglacial.
The Last Interglacial is known as the Eemian in northern Europe (sometimes used to describe the global interglacial), Ipswichian in Britain, the Mikulino (also spelled Milukin) interglacial in Russia, the Kaydaky in Ukraine, the Valdivia interglacial in Chile, and the Riss-Würm interglacial in the Alps. Depending on how a specific publication defines the Sangamonian of North America, the Last Interglacial is equivalent to either all or part of it.
