Fredrik Charpentier Ljungqvist

Fredrik Charpentier Ljungqvist is a Professor of History, especially Historical Geography, at Stockholm University, with a concurrent Associate Professorship in Physical Geography at the same institution. His research bridges climate science and historical analysis through interdisciplinary environmental and climate history studies, focusing on Europe and global regions. He has actively contributed to climate history understanding via dendrochronological methods, paleoclimatic reconstructions, and societal-climate interaction analyses.

Professor Ljungqvist's work includes significant projects on the Integrated History and Future of People on Earth (IHOPE) program’s scientific steering committee, and past roles with the UN Climate Panel IPCC, the PAGES 2k network, and the Swedish Research Council. He has conducted visiting research at the University of Cambridge, University of Bern, Freiburg Institute for Advanced Studies (FRIAS), and the Norwegian Academy of Sciences and Letters.

His research spans climate variability impacts on pre-industrial societies, including grain harvest and price relationships with climate factors, plague history connections to building activity patterns, and comparative legal analysis of Nordic medieval laws. He has published extensively in both scientific and popular science formats, with notable works including Climate and Man for 12,000 Years (2017), The Long Middle Ages (2015, updated 2022), and Europe Today (2024).

Scientific Recognition

• Rettig Prize (2022) from the Royal Swedish Academy of Sciences for interdisciplinary climate-disease research
• Clio Prize (2016) for public science communication

His methodological approach combines proxy records like tree-ring data with documentary sources, statistical modeling, and Earth System climate simulations. Current teaching responsibilities span both history and paleoclimatology courses, including supervision of one primary PhD student in history and two co-supervised students across history and physical geography disciplines.
