My research efforts emphasize environmental change of polar regions, with a focus on glaciologic problems. The choice of polar glaciology reflects the unique and powerful contributions that this subdiscipline makes to environmental change research. Ice core reconstructions of environmental history offer the most comprehensive, varied, and high-resolution view yet achieved of past environments. The ice sheets themselves are a major control on global sea level and albedo, and on high-latitude atmospheric and oceanic circulations, and on physical landscape characteristics. No other topographic features of this size and importance are changeable on such short time scales.
I use a quantitatively rigorous and novel blend of geophysical and geochemical techniques to address questions that are important in this context: How have climatic temperature and atmospheric greenhouse gas concentrations covaried in the past? What is the tempo and magnitude of climate changes in polar regions? What determines the isotopic composition of precipitation? How have the great ice sheets changed in the past, and how will they change in the future? How do they flow? How are microphysical processes in ice manifest at the scale of whole glaciers and ice sheets?
