WUOT Interviews Tree Ring Detective Grissino-Mayer

Henri Grissino-Mayer, professor in the Department of Geography and an expert in using tree rings to reconstruct past climates, recently spoke with WUOT‘s Megan Jamerson about his research.

You probably remember from your grade-school science classes the tidbit that the growth of a tree is recorded in concentric rings visible when the tree is cut down. Grissino-Mayer will tell you there’s a lot more information encoded in those rings. The layers record climate change, forest fires, pollution and more.
