Malcolm K. Hughes

Malcolm K. Hughes is a meso-climatologist and Regents' Professor of Dendrochronology in the Laboratory for Tree-Ring Research at the University of Arizona. He was born in Matlock, Derbyshire, England, and earned a Ph.D in ecology from the University of Durham. Since 1998, he is a fellow of the American Geophysical Union. His research is on the nature of climate variability, specifically focusing on the timescales of years to centuries. He uses natural recorded records such as tree rings.^[1]

Hughes has studied geographical areas including Europe, Asia, and the Sierra Nevada. In addition of tree rings, Hughes uses ice cores, laminated sediments, and the historical temperature record to help understand past climates.^[2] In 1998, he was a co-author with Michael E. Mann and Raymond S. Bradley on a paper which later spurred the hockey stick controversy.
