Carson Fellow Lajos Rácz explains the importance of climate history for the overall history of early modern Hungary. Documented climate data has only been in existence since the nineteenth century; therefore, Rácz reconstructs the pre-nineteenth century Hungarian climate from primary sources like diaries and letters. He uses such historical climate data in order to analyze how climate impacted the manner of everyday life during this era. Lajos Rácz is a professor at Szeged University and a visiting professor at Central European University, Budapest. He has specialized in climate and environmental history research since 1985.
