University of Rochester Ice Core Lab


Our research aims to understand natural and anthropogenic climate change through a lens of atmospheric composition. We use ancient air trapped in glacial ice from Greenland and Antarctica to learn about how the concentrations and isotopic composition of greenhouse gases and reactive gases have varied in the past, and what these changes tell us about Earth’s climate and atmospheric chemistry.
