Climatology Group

Mission: We study high-resolution climate variability through the analysis of tree-rings and other palaeoclimate archives at regional to global scales. Instrumental climate data are evaluated and used for the calibration of these archives to reconstruct climate over the past couple hundred to thousand years. We teach introductory and methodological courses on climatology with emphasis on spatial patterns and long-term changes of climate and ecological variability.


Recent paper: Eastern Mediterranean summer temperatures since 730 CE from Mt. Smolikas tree-ring densities.A millennial-length temperature reconstruction has been published representing the northeastern Mediterranean. The reconstruction is based on measurements of maximum latewood densities from ancient Pinus heldreichii in Northern Greece including the oldest tree in Europe (“Adonis”). The density chronology calibrates exceptionally well against instrumental temperatures (see the figure above). Details on the reconstructed temperature history can be found here:  Esper_2020_CD.pdf
