Bess Koffman, assistant professor of geology, studies past changes in Earth’s climate system using a combination of field and laboratory approaches. She is interested primarily in understanding how and why the atmospheric circulation has changed through time and the impacts these changes have had on terrestrial and marine environments. Earth’s atmospheric circulation influences large-scale climate variability in several important ways: it affects the transport and delivery of oceanic heat; it exerts a strong influence on the exchange of carbon dioxide (CO2) between the ocean and atmosphere, and it plays a large role in determining global rainfall distribution. Further, because the atmosphere can respond rapidly to climate perturbations, it is central to understanding the mechanisms driving changes in Earth’s climate on a range of timescales.
