Guest: Valerie TrouetForests can offer us picturesque views, but did you know they also offer us a look at the past? Why is that important? To better understand our climate, we need to study the past, and inspecting tree rings is a great way to do that! We’re ringing in the new year by talking to Valerie Trouet from the University of Arizona. She uses tree rings to study past climates, forest ecosystems, atmospheric circulation patterns and more. We’ll discuss what tree rings can actually tell us about our planet’s history and how we can use that to protect future generations.See Privacy Policy at https://art19.com/privacy and California Privacy Notice at https://art19.com/privacy#do-not-sell-my-info.
