Malcolm K. Hughes is a meso-climatologist and Regents' Professor of Dendrochronology in the Laboratory for Tree-Ring Research[1] at the University of Arizona .[3] [4] [5] [6]
Education and early life
[ edit ]
Hughes was born in Matlock, Derbyshire, England, and earned a Ph.D in ecology from the University of Durham .[7]
Career and research
[ edit ]
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 .[8] [9] [10] [11] [12]
Hughes has studied geographical areas including Europe, Asia, and the Sierra Nevada. In addition to tree rings, Hughes uses ice cores , laminated sediments , and the historical temperature record to help understand past climates.[13] [14] [15] [16] [17] In 1998, he was a co-author with Michael E. Mann and Raymond S. Bradley on a paper which produced the first eigenvector -based climate field reconstruction (CFR) incorporating multiple climate proxy data sets of different types and lengths into a high-resolution reconstruction of northern hemisphere temperatures. In 1999 the same team extended the method to cover 1,000 years, producing what was dubbed the hockey stick graph .[2]
