Research on historical dune activity has raised concern among environmental scientists and serves as a foundation for assessing recent and future changes in arid and semi-arid ecosystems. Disagreements related to the causes of historical dune activation persist because of the lack of a more detailed dune activity history for China's east dunefields. Based on stratigraphic evidence, historical documents and archaeological discoveries in the Mu Us and Horqin dunefields, this study presents a detailed dune activity history as well as the forcing mechanisms for China's east dunefields as a whole over the past millennium. The results revealed that two episodes of extensive dune activation (from 800 to 940 <span>ce</span> and from 1300 to 2000 \u0000<span>ce</span>) occurred in China's east dunefields, accounting for 69% of the past millennium. The proportions of extensive dune activation driven by a cold and dry climate (from 800 to 940 \u0000<span>ce</span> and from 1300 to 1730 \u0000<span>ce</span>), strong human activity (from 1900 to 2000 \u0000<span>ce</span>) and their combined impacts (from 1730 to 1900 \u0000<span>ce</span>) were approximately 68%, 12% and 20%, respectively. Thus, China's east dunefields were in a state of extensive dune activation for most of the past millennium, and most extensive dune activation was driven by climate.

The reconstruction of shore displacement was based on diatom analysis of radiocarbon-dated sediment cores from three lake basins combined with previously published lake isolation data. The resulting curve was used to construct palaeogeographical maps for selected time windows. Land-cover changes were inferred from pollen data from three lakes using the Landscape Reconstruction Algorithm with its two models REVEALS and LOVE. Our data suggest that people took advantage of the land gained due to an overall fall in relative sea level from ~35 to ~3 metres above sea level (m a.s.l.) over the last 10 000 years, interrupted by periods of transgression and highstands.

To explore this mechanism, we performed numerical experiments with an atmosphere–ocean–sea ice model. In these experiments, the impact of a large flush of Arctic sea ice was compared to a reference glacial state of the climate. In our results, the sea ice flush produces a major surface freshening of the North Atlantic Ocean and a 17% weakening of the strength of the Atlantic Meridional Overturning Circulation. Together with an increase in surface albedo, this weakening in ocean circulation leads to a cooling over the North Atlantic, extending to the downwind continents. Compared to our reference glacial state, the cooling reaches 5°C and lasts about 80 years. This climate anomaly is similar in magnitude and duration to relatively short cooling events during the last deglaciation, such as the Older Dryas, the Inter-Allerød cold period and the Preboreal Oscillation. We thus conclude that the sea-ice flush mechanism is consistent with the occurrence of such cooling events in the North Atlantic region.

Examining the remnants of past glaciations preserved in isolated alpine environments provides insight into critical palaeoclimatic conditions. Accurate dating techniques, such as terrestrial cosmogenic nuclides, are crucial for understanding the timing of these changes. The Anatolian Peninsula, characterized by diverse topographical and climatic factors, witnessed the presence of glaciers during the Late Pleistocene, shaping its alpine landscape significantly. While mountain ranges such as the Taurus and Pontic favoured glacier development due to their elevation and lower temperatures, isolated mountains such as Mount Soğanlı in the interior hinterland also supported significant palaeoglaciers. Despite previous studies on Anatolia's glaciers, numerical dating of glacial deposits on Mount Soğanlı has remained elusive until now, hindering precise palaeoclimatic interpretations. This study employs cosmogenic ³⁶Cl surface exposure dating and physical-based ice-flow modelling using an open-source framework, Parallel Ice Sheet Model (PISM), to determine the timing of glaciations and to reconstruct past glacier extents on Mount Soğanlı. The results reveal glacier retreat ages of 48.3 ± 13.4 and 18.3 ± 4.4 ka based on two well-preserved moraines. Additionally, palaeoclimate simulations matched with the field observations indicate considerably colder conditions (6.65–8.15°C colder than today) necessary to sustain glaciers on Mount Soğanlı, when precipitation amounts were the same as today.
