Tree Rings and Climate Change

NPR
Episode 172: Charlotte Pearson, assistant professor in tree ring research at the University of Arizona.

Tree ring research is more than just determining the age of trees. Trees can relay information about climate history that goes beyond simple weather records about rainfall or temperature change. The University of Arizona was a pioneer in the study of tree rings in the 1920s, and tree ring research has since become a field of study worldwide. U of A scientists have studied the historical of record of trees dating back 5,000 years.

Charlotte Pearson spoke to Prof. Tim Swindle of the University of Arizona Lunar and Planetary Laboratory.
