Most temperate trees put on a single ring each year, a fact known since the Middle Ages. These rings help tell us how old the tree is, but did you know that these rings encode information about climate, fire, insects and other influences? Dr. Malcolm Cleaveland specializes in the use of tree rings to reconstruct paleoclimate. He will discuss how the variability forms unique patterns that can be used to date historic timbers and environmental events. Learn how the dating is done and explore the many applications.
