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: Precise date for the Laacher See eruption synchronizes the Younger Dryas.

 

The Laacher See Eruption (LSE) has been re-dated to 13,006 years BP using in-situ tree samples buried by pyroclastic materials. The re-dating was feasible using the substantially improved 14C calibration curve, after including dozens of ancient pine trees from Switzerland in this record. The new LSE date synchronizes the paleoenvironmental records from Europe (blue in the figure) with the ice core records from Greenland (black), and thereby requires a re-interpretation of the Younger Dryas.
