The work of the Kemp team is focused on unravelling the climate history of the Earth through analysis of the sedimentary record. We use tools like geochemistry, sedimentology and numerical modelling to understand the causes, consequences and timescales of past environmental change, and how these changes are preserved in the geologic record. The team works across multiple disciplines, time intervals and timescales.
