Researchers have discovered that the Little Ice Age may have affected Transylvania later than other parts of Europe, with hot weather persisting through much of the 16th century.
Historical documents describe extreme weather events in Transylvania, including a particularly hot and dry summer in 1540, followed by heavy rainfall and floods in the 1590s.
Climatic variations led to significant catastrophes such as famine, plague, and locust invasions, highlighting how communities adapted to and were impacted by extreme weather.
Romanian researchers are turning to both nature’s and society’s archives to reconstruct the climate of past centuries. While glaciers, sediments, and pollen offer insights into natural history, written documents such as diaries, travel notes, and monastery registers provide a human perspective on climate events and their impact. This research has been published in the journal Frontiers in Climate.
Transylvania’s Unique Climate Pattern
The Little Ice Age, a period of cooler temperatures that intensified in the 16th century, significantly affected the western parts of Europe, with temperatures dropping by 0.5°C during the latter half of the century. However, in Transylvania, hot weather was recorded more frequently than cold weather during the 16th century.
“This makes us believe that the Little Ice Age could have manifested itself later in this part of Europe,” said Tudor Caciora of the University of Oradea who also was one of the lead authors of the study.

Historical sources reveal that the first half of the 16th century was marked by particularly hot and dry conditions. “One compelling passage comes from a historical document describing the summer of 1540. ‘The springs dried up, and the rivers dwindled to mere trickles. Livestock fell in the fields, and the air was thick with despair as the people gathered in processions, praying for rain,’” Caciora noted. “This vivid account underscores the emotional and spiritual dimensions of living through climatic extremes.”
In contrast, the second half of the century was characterized by heavy rainfall and floods, particularly during the 1590s.
Climate Catastrophes and Adaptation
These climatic variations often led to catastrophes, including 30 years of Black Death outbreaks, 23 years of famine, and nine years of locust invasions.
“However tragic, weather extremes and resulting calamities could have driven changes in settlement patterns,” the researchers explained. “Towns might have adopted flood-resistant infrastructure or migrated to more favorable areas. The challenges might also have spurred technological innovations, such as improved irrigation systems or storage facilities,” Caciora added.
The Human Element

“Chronicles and diaries reveal how people perceived, responded to, and were impacted by these events,” said Caciora.
Despite the insights they provide, the study faces limitations. Reports are often subjective or only reflect local conditions, and records are sometimes fragmented or absent. For example, the researchers were unable to find consistent records for 15 years of the 16th century due to a lack of documentation or contradictory accounts.
Nevertheless, these writings not only offer a glimpse into how people in the past experienced climate events but are also relevant for modern climate resilience strategies. “Studying climate records from the society’s archive is as crucial as analyzing natural proxies,” Caciora explained. “It provides a human-centric perspective on past climatic events.”
