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.
- Quantifying cosomogenic production of 14C in glacial ice
- Understanding past changes in the global CH4 budget
- Reconstructing the history of atmospheric CO concentrations and stable isotopic composition
