What Tree Rings Tell Us About History and Climate Change


Did you know trees can talk? They tell us so much about the past, current weather conditions, and what the future might hold. Dedronchonologists use the annual growth rings in a tree to date events, track environmental changes, and tell us about the construction date of buildings. Dr. James Speer from Indiana State University’s Department of Earth and Environmental Systems will share the secrets trees have to share with us.
