Meteorology has never been as precise as it is todaybut how can scientists learn about past weather events?
Researchers in Romania have analyzed historical records to reconstruct 16th-century weather patterns and their effects on society in Transylvania.

The historical sources report that the first half of the sixteenth century was unusually hot and dry in Transylvania.
One compelling passage comes from a historical document describing the summer of 1540, Caciora explained.
The springs dried up, and the rivers dwindled to mere trickles.
This vivid account underscores the emotional and spiritual dimensions of living through climatic extremes.
The challenges might also have spurred technological innovations, such as improved irrigation systems or storage facilities.
Overall, however, the documents testified to more frequent hot weather than cold weather throughout the 16th century.
His teams hypothesis of the delayed cooling period is bolstered by later testimonies of decreasing temperatures.
The researchers did, however, note some limitations to their approach.
Furthermore, first-hand reports only testify to local experiences and could be subjective to the author.
Nevertheless, studying climate records from the societys archive is as crucial as analyzing natural proxies, Caciora concluded.
It provides a human-centric perspective on past climatic events.
