About us

The research group explores environmental- and climate change. It focuses on ameliorating the interpretation of paleoclimatological information using quasi continuous (e.g. physical and chemical parameters of tree rings and ice cores) and event based (e.g. moraine) environmental archives. Moreover, our group searches for new sites and similar archives for further research.

These aims fall in line with the internationally accepted idea, that nowadays instead of the graph describing the global average temperature change, regional climate reconstructions with highly precise chronology, calibrated via instrumental records and with well defined uncertainties became the main cornerstones. These can help in understanding the climate variability originated in natural and anthropogenic factors.
