Pitt Researchers Able to Better Pinpoint History of Droughts in American West Through Exploration of Tree Rings, Oxygen Isotopes
Description: Through an exploration of tree rings and oxygen isotopes, researchers are now able to better pinpoint the history of droughts in the arid and semiarid areas of the American West. A new paper explores the Medieval Climate Anomaly, a particularly warm period occurring in the northern hemisphere of the American West around 950 to 1250 C.E. While this time period is known as being a "dry period," researchers have discovered an unexpected complexity to the patterns of drought. [Source: University of Pittsburgh]
