ITL dating resolves chronology of Quesang travertine hand- and footprints, Tibetan plateau
New evidence of prehistoric human activity on the central Tibetan plateau during the early to middle Holocene
The cold and hypoxic environment of the Tibetan Plateau was a major challenge for its prehistoric human occupants. The earliest known hominin occupation (or visitation) of the Tibetan Plateau was at ~200 ka, in the middle Pleistocene, and these hominins must have had survival strategies for this harsh environment. We report the discovery of 5 handprints and 17 footprints on the travertine near the outlet of the Quesang hot spring, a well-document…
Climate change, state capacity and nomad–agriculturalist conflicts in Chinese history
Proxy-based temperature reconstruction in China for the Holocene
Optical dating of Holocene paleosol development and climate changes in the Yili Basin, arid central Asia
Optically stimulated luminescence (OSL) dating was conducted on the K-feldspar and quartz fractions of a Holocene loess-paleosol sequence in the Yili Basin, in the core area of arid central Asia (ACA). Age overestimation using the post-IR IR (pIR 50 IR 170 ) signals from feldspar was observed for paleosols, because of poor bleaching prior to deposition. Therefore, a reliable age framework for the studied section was established using OSL dating o…
Population collapses in the pre-modern period
Long-term association between climate change and agriculturalists’ migration in historical China
Based on 1686 records of agriculturalists’ migration and 4417 events of social crisis (wars, famines, and epidemics) together with various statistical methods, we constructed a conceptual model that includes both climatic and social factors to explain the long-term dynamics of agriculturalists’ migration in historical China over the last two millennia. Also, we framed our research under the paradigm of environmental humanities to help reinterpret…
Temperature and precipitation effects on agrarian economy in late imperial China
Climate change has been statistically proven to substantially influence the economy of early modern Europe, particularly in the long term. However, a detailed analysis of climate change and the economy of historical China remains lacking, particularly from a large-scale and quantitative perspective. This study quantitatively analyzes the relationship between climate change and the economy in late imperial China (AD 1600-1840) at the national leve…
Demographic impact of climate change on northwestern China in the late imperial era
Contextualizing human migration in different agro-ecological zones in ancient China
Evaluating the effectiveness of agricultural adaptation to climate change in preindustrial society
The effectiveness of agricultural adaptation determines the vulnerability of this sector to climate change, particularly during the preindustrial era. However, this effectiveness has rarely been quantitatively evaluated, specifically at a large spatial and long-term scale. The present study covers this case of preindustrial society in AD 1500–1800. Given the absence of technological innovations in this time frame, agricultural production was chie…
Reconstruction of the geographic extent of drought anomalies in northwestern China over the last 539 years and its teleconnection with the Pacific Ocean
Recent paleo-climatic/environmental studies have resulted in several high-resolution paleo-precipitation/moisture reconstructions in Northwestern (NW) China over extended periods. Nevertheless, those reconstructions are mostly about the climatic history of individual sites, while fine-grained portrayal and analysis of the geographic extent of drought anomalies across the entire NW China are still missing. We based our study on the dryness/wetness…
Epidemics in Ming and Qing China
Long-term relationship between climate change and nomadic migration in historical China
We investigated the relationship between a 2000-year history of nomadic migration and climate change in historical China. By using updated data and statistical methods, the study solved several unanswered questions from past research about the relationship between climate change and the nomadic migration, especially over the long term and on a large spatial scale. The study used correlation analysis, multiple regression analysis, and Granger caus…
Carbon emission right as a new property right
Clean development mechanism (CDM) is encountering many uncertainties due to the coming end of the commitment period and critically suggested reformation. As the largest participant in the CDM market, China shoulders the biggest proportion of market risk. Among the studies on CDM in China, few have focused upon the legal aspect of CDM, which is crucial in defending developers’ interests. To fill this research gap in making the transition from poli…
Extreme dust storm disaster in northern China in AD 1523
The dust storm disaster in northern China in AD 1523 was extremely severe. In the present study, the history of the disaster was reconstructed by using historical Chinese documents. Our results show that during the dust storms, the horizontal visibility dropped below 0.05 km, while the wind speed surpassed Scale 10 of the Beaufort Wind Force Scale (i.e., 88–103 km/h). The dust storms severely affected agriculture, resulting in crop failures and f…
Temperature change and natural disasters in northwestern China
It is projected that global warming will result in more natural disasters in the world. However, the global projection about the temperature-disaster association is based on instrumental records (<100 yr), which may be too short to account for the very long-term dynamics between temperature change and natural disasters. Besides, the temperature-disaster association may vary in different regions because of the influence of regional meteorology and…
The causality analysis of climate change and large-scale human crisis
Recent studies have shown strong temporal correlations between past climate changes and societal crises. However, the specific causal mechanisms underlying this relation have not been addressed. We explored quantitative responses of 14 fine-grained agro-ecological, socioeconomic, and demographic variables to climate fluctuations from A.D. 1500–1800 in Europe. Results show that cooling from A.D. 1560–1660 caused successive agro-ecological, socioec…
Time Lag in the Climate Change, War, and Population Relationship
Wars became more frequent in a cold climate at the macro-historical scale. However, war peaks and their associated population collapses appeared 20–30 years after the commencement of a cold climate. Following Zhang et al.'s (2007a) conceptual model, this paper sought to further examine the climate-war-population time lag by using mathematical means. Result was: the relatively slow natural population adjustment to the climate-induced fluctuations …
Global climate change, war, and population decline in recent human history
Although scientists have warned of possible social perils resulting from climate change, the impacts of long-term climate change on social unrest and population collapse have not been quantitatively investigated. In this study, high-resolution paleo-climatic data have been used to explore at a macroscale the effects of climate change on the outbreak of war and population decline in the preindustrial era. We show that long-term fluctuations of war…
