“…Such climatic events were especially important in influencing man-land relationships in ACA (Yin et al, 1992). The climatic and environmental evolution of ACA has been reconstructed from various geological archives, such as lake sediments Chen et al, 2008;Ding et al, 2002;Mathis et al, 2014;Mischke & Wünnemann, 2006;Rhodes et al, 1996;Ricketts et al, 2001;Rudaya et al, 2009), loess (Chen et al, 2016;Li et al, 2016), peats (Hong et al, 2014), and sand dunes (Long et al, 2017(Long et al, , 2014. Most of these studies have addressed long-term climatic and environmental changes (e.g., Chen et al, 2008;Ding et al, 2002), and in addition the proxy records typically have relatively large age uncertainties and low temporal resolution.…”

Numerous studies have been conducted on the Holocene climatic evolution of arid central Asia (ACA) using various geological proxies. However, the quality of the age control and the temporal resolution of the proxy records used make it difficult to characterize hydroclimatic changes on centennial to multidecadal timescales. Here we present a stalagmite δ18O record from Baluk cave in Xinjiang, NW China, in ACA, which has an average 22.8‐year resolution and provides a record of inferred hydroclimatic changes from 8.4 to 2.7 ka. Abrupt hydroclimatic shifts are evident during the following intervals: 2.75–2.90, 3.25–3.35, 3.75–3.85, 4.45–4.55, 4.75–4.90, 5.05–5.15, 5.2–5.3, 5.4–5.5, 5.9–6.0, 6.2–6.3, 6.4–6.5, 6.8–6.9, 7.1–7.6, 7.85–7.95, and 8.05–8.25 ka. Notably, an overall in‐phase relationship is observed between the hydroclimatic variations and change in solar activity, and the results of spectral analysis suggest the presence of the Eddy (~1,080 years), de Vries (~205 years), and Gleissberg (~88–102 years) cycles. This indicates a linkage between solar activity and hydroclimatic changes in ACA on centennial to multidecadal scales during the Holocene. We suggest that the influence of solar activity on hydroclimatic changes in ACA occurs via its effects on North Atlantic sea surface temperature, North Atlantic Oscillation, northern high‐latitude regional temperatures, and via direct heating. The relationship suggests that solar activity may play an important role in determining future hydroclimatic changes in ACA.

Changes in East Asian summer and winter monsoon intensity have played a pivotal role in the prosperity and decline of society in the past, and will be important for future climate scenarios. However, the phasing of changes in the intensity of East Asian summer and winter monsoons on millennial and centennial timescales during the Holocene is unclear, limiting our ability to understand the factors driving past and future changes in the monsoon system. Here, we present a high resolution (up to multidecadal) loess record for the last 3.3 ka from the southern Chinese Loess Plateau that clearly demonstrates the relationship between changes in the intensity of the East Asian summer and winter monsoons, particularly at multicentennial scales. At multimillennial scales, the East Asian summer monsoon shows a steady weakening, while the East Asian winter monsoon intensifies continuously. At multicentennial scales, a prominent ~700-800 yr cycle in the East Asian summer and winter monsoon intensity is observed, and here too the two monsoons are anti-phase. We conclude that multimillennial changes are driven by Northern Hemisphere summer insolation, while multicentennial changes can be correlated with solar activity and changing strength of the Atlantic meridional overturning circulation.

“…Mingsha Shan Sand Dunes are composed of these different types of dunes, with downwind evolution of dune geomorphology that consists of the youngest protodunes to the northwest and the highest dunes to the southeast (Figure 2a,b Pollen analysis of sedimentary cores from Balikun Lake indicated that the local climate was extremely dry, with basin-wide desert and/or desert steppe vegetation present at~30-8.6 ka (An et al, 2012;Zhao et al, 2015). Aeolian sand dune records in the Bayanbulak Basin,~700 km to the west of the Balikun Basin, revealed a very dry climate and highly intensified aeolian activities during the early Holocene (12-7.5 ka; Long et al, 2017). The synthesized research also revealed that the lakes in ACA had very low water levels and even dried up before 8 ka (Chen et al, 2008).…”

Westerlies-dominated arid central Asia (ACA) has a very fragile ecological environment that highly depends on the available moisture sources. However, the moisture history of this region during the Holocene has been a controversial topic for several decades. Here, we performed optically stimulated luminescence (OSL) dating and grain-size analysis of aeolian sediments from the eastern Balikun Basin. Our results demonstrated that the early Holocene climate in the Balikun Basin was dry (beforẽ 6.5 ka) and then became wetter during the mid-late Holocene. This Holocene climate pattern correlates well with other climatic inferences from various proxies acquired at various ACA locations, further supporting an earlier view that the Holocene climate in ACA was out of phase with that of the East Asia summer monsoon. Furthermore, an extremely dry event at 4.3-2.6 ka correlated well with pollen records and a decrease of~4°C in temperature in the western Balikun Lake, but this event was not evident in other ACA regions. Finally, Mingsha Shan Sand Dunes in the eastern Balikun Basin initially accumulated in the earliest Holocene. We suggest that the early Holocene dry climate in the ACA region and the local geomorphology are responsible for the formation of the Mingsha Shan Sand Dunes.
