Study details 17th-century Transylvanian climate via historical records

Researchers from the University of Oradea analyzed 937 historical accounts to document climate extremes in 17th-century Transylvania. The study, published in PLOS Climate, cross-referenced town records, church logs, and diaries with physical evidence like tree rings to confirm 55 exceptionally harsh winters.

The team identified that 36 of these severe winters occurred between 1645 and 1700, a period marked by the Little Ice Age. Beyond cold, records indicate frequent excessive rainfall contributed to crop failures, skyrocketing food prices, and disease outbreaks. These environmental stressors exacerbated the daily struggles of populations already facing war and political instability.
