While ongoing climate change affects a number of meteorological drivers relevant to plant functioning, an increase in the frequency and severity of drought events may ultimately have the largest impact on ecosystem carbon cycling. Much of what we know about tree response to drought comes from the relatively dry western U.S., where droughts are prolonged and often lead to tree mortality. Less attention has been focused on the humid eastern US, where drought-induced mortality is rarer but drought-related declines in carbon uptake and growth are nonetheless profound. Using a well replicated network of tree rings, I will present work that better examines how climate, particularly drought can impact tree growth and how that relates to carbon uptake.
