Climatic signatures in early modern European grain harvest yields

2022

Abstract. The association between climate variability and grain harvest yields has been an important component of food security and economy in European history. Yet, inter-regional comparisons of climate–yield relationships have been hampered by locally varying data types and use of different statistical methods. Using a coherent statistical framework, considering the effects of diverse serial correlations on significance, we assess the temperature and hydroclimate (precipitation and drought) signatures in grain harvest yields across varying environmental settings of early modern (c. 1500–1800) Europe. An unprecedentedly large network of yield records from northern (Sweden), central (Switze…
