NATURAMA Lecture: Ancient Trees Tell Climate Stories

Information on past environmental events is stored in the tree rings: The width of these growth rings has been used for many years to reconstruct past climatic conditions from larch, oak or Scots pine. Thanks to new approaches, artificial intelligence and the measurement of several million individual tree cells, a solid climate signal can now also be obtained from the Swiss stone pines – and other previously "spurned" tree species. In his lecture, Markus Stoffel takes us on a journey to gigantic, ancient giant trees and microscopic wooden cells. He shows how cores from trees, such as those from the God da Tamangur, can be used to document the condition of the Silvretta glacier or the climate in the eastern Alpine region since Roman times. | The Schlossstall Auditorium of the Swiss National Park is located right next to the castle. 10 minutes from the train station.
