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, socioeconomic, and demographic catastrophes, leading to… 

Quantitative Analysis of Climate Change and Human Crises in History

The association between climate change and human crises in history was conceived a century ago. Yet, it remained controversial and even questioned in academia for some time because it was usually

Macro-Economic Cycles Related to Climate change in Dynastic China

Climate Change and Macro-Economic Cycles in Pre-Industrial Europe

The scale thinking in the analysis is raised as an essential methodological issue for the first time to interpret the associations between climatic impact and macro-economy in the past agrarian society within different temporal scales.

Demographic Crises of Different Climate Phases in Preindustrial Northern Hemisphere

This research empirically analyzes the association between climate change, population size, and demographic crises as indicated by what we term “population checks,” or major wars, epidemics, and

Climate change and fiscal balance in China over the past two millennia

The relation between climate change and historical rhythms has long been discussed; however, this type of study still faces the lack of high-resolution data of long-term socio-economic processes. In

Temperatures, food riots, and adaptation: A long-term historical analysis of England

A large body of research indicates that environmental conditions can influence the risk of social unrest. However, we know little about how these effects may change in the long run. Are they likely

Bucking the trend: Population resilience in a marginal environment

Evaluating the impact of environmental changes on past societies is frequently confounded by the difficulty of establishing cause-and-effect at relevant scales of analysis. Commonly,

Towards a rigorous understanding of societal responses to climate change.

An interdisciplinary framework for uncovering climate-society interactions that emphasizes the mechanics by which climate change has influenced human history, and the uncertainties inherent in discerning that influence across different spatiotemporal scales is proposed.

A preliminary analysis of economic fluctuations and climate changes in China from BC 220 to AD 1910

Understanding the socioeconomic effects of past climate change is valuable for sustainable social development. However, quantitative analyses of the long-term relationships between climate change and



Climate change and large-scale human population collapses in the pre-industrial era

Aim It has long been assumed that deteriorating climate (cooling and warming above the norm) could shrink the carrying capacity of agrarian lands,depriving the human population of sufficient

Global climate change, war, and population decline in recent human history

It is shown that long-term fluctuations of war frequency and population changes followed the cycles of temperature change, which implies that climate change may have played a more important role and imposed a wider ranging effect on human civilization than has so far been suggested.

Climate change, social unrest and dynastic transition in ancient China

The evident connection between human evolution and climatic changes has been concurred by scientists. Although many people are trying to forecast the impacts of climatic changes on our future

Climatic Change, Wars and Dynastic Cycles in China Over the Last Millennium

In recent years, the phenomenon of global warming and its implications for the future of the human race have been intensively studied. In contrast, few quantitative studies have been attempted on the

Periodic climate cooling enhanced natural disasters and wars in China during AD 10–1900

This study suggests that food production during the last two millennia has been more unstable during cooler periods, resulting in more social conflicts owing to rebellions within the dynasties or/and southward aggressions from northern pastoral nomadic societies in ancient China.

Climatic change and Chinese population growth dynamics over the last millennium

The climate–population relationship has long been conceived. Although the topic has been repeatedly investigated, most of the related works are Eurocentric or qualitative. Consequently, the

Changes in climate and secular population cycles in China, 1000 CE to 1911

Many studies of secular population cycles in historical China conclude that when popula- tion is large — relative to the land's carrying capacity — further population increase can lead to mortal- ity

Temperature, aridity thresholds, and population growth dynamics in China over the last millennium

The relationship between climate and population has long been discussed, but rarely has it been quantitatively measured. Hence, the relationship remains ambiguous. In the present study, we employ

Paleoclimatic studies indicate four epochs of global cooling during the last 4 000 years, i. e. during the few centuries before and after 2000 BC, 800 BC, 400 AD, and 1 600 AD; the quasiperiodicity

Climate change and violent conflict in Europe over the last millennium

We investigate the relationship between a thousand-year history of violent conflict in Europe and various reconstructions of temperature and precipitation. We find that conflict was more intense
