Kirk Allen Maasch is Professor in the School of Earth and Climate Sciences and the Climate Change Institute at the University of Maine. He has over 20 years of experience using climate models and statistical methods to investigate the causes of climate change across time scales ranging from years to millions of years. The models range in complexity from simple low-order dynamical systems to complex three-dimensional models of the atmosphere. He has worked toward developing a theory for long-time scale climate change (ice ages and millennial scales). His most recent interests include inter-annual to decadal scale climate variability in the Holocene and the relationship between climate change and human activities, as well as model projections of climate change over the next century.
