Since 1979, the Arctic has warmed nearly four times faster than the global mean . Recent mass loss from Arctic glaciers has contributed to sea level rise at a comparable rate to the vast Greenland Ice Sheet . The loss of glaciers is also expected to have numerous local impacts on hydrological, ecological, and human systems. Although it is virtually certain that glaciers will continue to lose mass over coming decades, large uncertainties remain in twenty-first century projections of ice loss from glaciers. These uncertainties have wide–ranging global and local scale implications including on projections of sea level rise and coastal flood risk, and for projections of the duration of freshwater supplies coming from glaciers. To address these limitations, my research program takes a cross-disciplinary approach and has drawn on tools from climate science, paleolimnology, glaciology, glacial geomorphology, remote sensing, and spatial analysis to provide a longer–term framework for anticipating the consequences of ongoing warming on the Arctic cryosphere.
