Reconstructing climate history

We work to reconstruct and understand the history of Earth's climate. Through a range of collaborative projects, we examine the ways that rainfall patterns, winds, permafrost and other parts of the Earth system have responded to natural climate changes in the past, and we use these records of past changes to benchmark the models and theories used to project the future. Our work uses careful field observations, precise dating using uranium and its daughter isotopes, geochemical data, and comparisons with climate model experiments.
