The Wisdom Of Trees

To chart the seasons, look to tree leaves. To understand the past, look inside to the tree’s rings. Valerie Trouet, associate professor in the Laboratory of Tree-Ring Research at the University of Arizona, joins host Krys Boyd to talk about what we can learn by looking inside tree trunks – everything from the science of climate change to momentous occasions in human history. Her book is called “Tree Story: The History of the World Written in Rings.”
