Mid-to-high latitudes of Asia and its adjacent Arctic area are some of the most sensitive regions to climate warming in Eurasia, but spatio-temporal temperature variation over this region is still limited by a lack of long-term temperature records. Here, June-July temperature reconstructions are developed from a Larix sibirica composite chronology that presents a stable positive linkage with large-scale recorded temperatures and spans 1190–2019 CE for the source area of the Northern Asian great river Basins, northern Mongolian Plateau, Inner Asia. The warmest reconstructed period and low summer sea ice extent in the Arctic Ocean over the past 830 years was estimated to occur in the late twentieth century (1990s–present), with a mean temperature (15.2°C) higher than the long-term mean (13.9°C) of 1190–2019 CE, which is linked with the rapid increase in global temperature. A relationship also exists between the reconstructed temperature and the AMO index, suggesting that the atmospheric patterns over the Arctic and North Atlantic Oceans influence the temperature variations of northern Mongolian Plateau. In addition, we also propose that the warm climate promoted high vegetation productivity and favored the formation of power of the nomadic tribes in the Mongolian Plateau, such as the warm periods 1210s–1250s and 1400s–1430s. Our temperature reconstruction provides us with an opportunity to understand the regional effects of climate warming from multiple perspectives.
