There is not much difference in mid- to late-Holocene climate change between in South Korea and in other parts of the northern hemisphere. According to paleoclimate data from South Korea, the Holocene Climate Optimum ended around 7600-6000 BP. Lower latitudinal areas seemingly showed later termination times of the Holocene Climate Optimum. In late-Holocene, the climate was relatively cool between AD 200-AD 800 and AD 1300-AD 1900 and relatively warm between AD 800-AD 1300. In addition, the climate might be relatively cool between 1200 BC-400 BC and relatively warm between 400 BC-AD 200.
