Our planet offers many sources of information on how past climates influenced the environment, such as glaciers, sediments, trees and pollen rings. But to rebuild past climatic events, researchers in the field of historical weather go beyond these natural indicators to examine those of society: the records and reports of the daily life of people who lived in those times.
Together, these ideas of the past help make more precise predictions on how climate change will affect our environment and society today and in the future. A new study published by Romanian researchers in Climate borders It presents such findings of historical documents that date back to Transylvania of the 16th century, shedding light on the socio -economic impacts of extreme climatic events of that time.

A deep immersion in the past
The researchers extracted data related to the newspaper climate and magazine entries, chronicles, travel reports and social records. These meteorological records come from a variety of sources, including records of monasteries, calendars and travel notes of diplomats, missionaries and monks.
These accounts document observations on snowfall, the life cycles of wild and cultivated plants (such as the moment of grape harvests and cherry flowers), fluctuations in gray prices, water level markers in buildings and stones , and artistic representations of frozen or dry rivers. These sources provide not only meteorological data but also information on how societies adapted to climatic changes, offering a more complete understanding of the role of climate in historical events.
After the statistical analysis, the researchers rebuilt a timeline of the climatic patterns in the Transylvania region (now Romania) and identified surprising trends. The first half of the 16th century was marked by extreme climatic events, including hot summers and severe droughts, particularly between 1527 and 1544, which devastated agriculture and took the famine. The second half of the century, on the contrary, saw excessive rains and severe floods, especially in 1590. Both climatic extremes resulted in a generalized food shortage, which caused a greater death due to hunger and disease, including sprouts of the plague.
Great problems in the little ice era
The 16th century marks a critical point in the history of the weather, since it coincided with a significant phase of Little Ice Age, a global cooling event that lasted from the fourteenth to the nineteenth century. During this time, temperatures in Europe fell approximately 0.5 degrees Celsius (0.9 degrees Fahrenheit) after 1560 compared to the previous periods. The cooling led to tougher winters and summers that were cold and rainy or dry, which resulted in bad harvests, famine and epidemics. In particular, in Western Europe, heat waves were less frequent and less intense than in Transylvania, which suggests regional variations in how the small ice age was manifested.
“This makes us believe that the small ice age could have later manifested in this part of Europe,” said study author Tudor Caciora of the Department of Geography, Tourism and Territorial Planning at the University of Orada, Romania, in a Press release.
The value of historical climatic records
According to Caciora, the analysis of social records is as valuable as studying environmental data because it provides a human -centered perspective on past climatic events. He explains that extreme climatic conditions and their consequences, by tragic, often stimulate societies to adapt. These adaptations may include the construction of flood -resistant infrastructure, develop technological innovations or even migrate to more hospital regions.
Understanding historical climate variability is crucial to interpret present and future climatic trends, especially during significant climatic periods such as Little Ice Age, which had deep socio -economic effects. The study highlights the crucial role of the weather in the configuration of the historical and economic panorama of Transylvania of the 16th century, which illustrate the complex interactions between climate and human society.
