At Quesang on the Tibetan Plateau we report a series of hand and foot impressions that appear to have been intentionally placed surface unit soft travertine. The travertine was deposited by water from hot spring which is now inactive as lithified it preserved traces. On basis sizes traces, suggest two track-makers were involved likely children. We interpret this event deliberate artistic act created work parietal art. traces imprinted dates between ∼169 226 ka BP. This would make site...
Abstract The Yellow River flow has decreased substantially in recent decades, and the river often dried up lower reach failed to sea. Climate change human disruption have been suggested as major causes of reduction, but quantification their relative contribution is challenging due limited instrumental records disturbance by dams. Here we use a basin‐wide tree ring network reconstruct for past 1,200 years show that exhibits marked amplitude variations are closely coupled hydrological mean...
The Yellow River has caused suffering to people with its devastating floods throughout human history. Understanding the occurrence of and their relationship climate change is crucial for sustainable water governance in North China. Here we synthesize historical climatic records basin investigate during past two millennia. Based on archives river levee breaches, developed a decadally resolved flooding frequency record from 221 BCE 1949 CE, which provides rare chance perceive river’s long-term...
Discrete diffusion models have emerged as a flexible and controllable paradigm for structured sequence modeling, yet they still lag behind causal language in expressiveness. To bridge the gap between two paradigms, we introduce CaDDi, discrete model that unifies sequential temporal modeling within non-Markovian framework. Unlike conventional operate step by with no access to prior states, CaDDi integrates trajectory, enabling more expressive generation. Our approach also treats special case,...
Abstract. The ancient Silk Road played a crucial role in cultural exchange and commercial trade between western eastern Eurasia during the historical period. However, exchanges were interrupted early 16th century CE, Ming dynasty. Various causes for decline of have been suggested. Unlike social factors, natural factors not adequately addressed. In this study, we use evidence from sedimentary site (Xishawo, XSW) Dunhuang oasis, together with analysis archives, to demonstrate occurrence...
Abstract. Long-term, high-resolution temperature records which combine an unambiguous proxy and precise dating are rare in China. In addition, the societal implications of past change on a regional scale have not been sufficiently assessed. Here, based modern relationship between chironomids temperature, we use fossil chironomid assemblages precisely dated sediment core from Gonghai Lake to explore variability during 4000 years northern Subsequently, address possible through statistical...
Recently, the desiccation effect of North Atlantic Oscillation (NAO) is found to be positively correlated with violent conflict in pre-industrial Europe, agricultural shrinkage and its subsequent economic shocks their causal link. However, it remains unexplored whether correlation persists if study period extended backward time, a different definition applied, or relationship examined at lower geographic levels. In this study, we based on 835 internal disturbance incidents Europe during...
On the basis of concentrations 21 major and minor elements in a well-dated sediment core from deepwater part Lake Erhai, principal component analysis (PCA) reveals three main factors controlling inorganic chemical composition lake sediments. These are physical erosion watershed (Component 1), autochthonous calcite precipitation water 2) early diagenesis sediments 3). Variations factor scores Component I 3 may reflect fluctuations rainfall temperature, respectively region. High correlate with...
Abstract Studies on the spatiotemporal relationship between historical climate change and patterns of population war are rare. In this research, statistical methods (such as correlation test Granger causality analysis) visualization technique applied to demonstrate how temperature, in terms long-term trend cyclic mode, fundamentally affects temporal-spatial variations center during imperial China (5–1911 CE). Results show that (1) consistent southward migration overall accords with...
Abstract Fluctuations in climatic proxies of the Milanggouwan section Salawusu River valley Ordos Plateau (Inner Mongolia, China) during Marine Isotope stage 3 (MIS 3) coincide well with sedimentary cycles for palaeo‐mobile dune sands alternating fluvial–lacustrine facies and palaeosols. We compared modern mobile (products a cold dry climate dominated by East Asian winter monsoon), whereas palaeosols were controlled wet–warm similar to that summer monsoon. The MIS appears have experienced at...
Recent studies show that wars were more prevalent during colder periods in human history. Nevertheless, the temporal consistency of climate-war correlation Europe over extended period has rarely been examined systematically. In this study, we European violent conflict record Conflict Catalog [Brecke 1999. "Violent conflicts 1400 A.D. to present different regions world." Paper presented at 1999 Meeting Peace Science Society (International), Ann Arbor, MI, 8–10 October 1999] back year AD900,...
Abstract: Studies of lithology, sedimentary facies and the distribution regularity SiO 2 Al O 3 contents /SiO ratio allow us to divide Upper Pleistocene‐Holocene Series represented by Milanggouwan section in China's Salawusu River valley into six segments: MGS1, MGS2, MGS3, MGS4, MGS5 MGS6. The boundary ages for MGS1 (the Dishaogouwan Dagouwan Formations), MGS2 upper Chengchuan Formation), MGS3 middle MGS4 lower (most strata Formation) MGS6 bottom Formation top Lishi correspond those MIS1,...
Abstract The Last Interglacial Period strata in the Milanggouwan section Salawusu River valley on Ordos Plateau, China, have 8.5 sedimentary cycles composed alternately of eolian dune sands, fluvio-lacustrine facies and paleosols. Based comprehensive analyses distribution magnetic susceptibility CaCO3 paleo-ecology indicated by fossils region, it is considered that sedimentation resulted from dry-cold warm-humid climate fluctuations. Magnetic values contents stratigraphic sectors I, III, V...
