This sub-theme focuses on climatic change and human-environment interactions on a range of temporal scales and using a variety of archival sources and proxies.
Our Environmental Reconstruction staff and PhD students are conducting research in a range of environments from the poles to the equator, from the land to the oceans. We have active research links with the British Geological Survey, where several of our staff are appointed as Visiting Research Associates via the Centre for Environmental Geochemistry.
Reconstructing past climates
We use deposits from terrestrial, lake and ocean environments to reconstruct past climates. We investigate climate changes over late Pleistocene and Holocene timescales using lake sediments (eg from Mexico, Australasia, and Turkey) and over longer timescales back into the Pleistocene from marine cores in high latitudes north and south. We also work on understanding more recent climate patterns from instrumental data to aid our reconstructions of past conditions.

Human impacts and their intersection with climatic change
We investigate human impacts and their intersection with climatic change through collaborations with archaeologists, social scientists, engineers and environmental scientists. This ranges from more recent issue around nitrogen deposition and cultural eutrophication to geoarchaeological investigation into the relationship between people, the environment and the climate over thousands of years.

Calibration, validation and development of novel proxies
The calibration, validation and development of novel proxies for environmental reconstruction is an important strand of our research. Through the Centre for Environmental Geochemistry we are leading research in the development of methodologies for the analysis and interpretation of stable isotopes and the development of models regarding the deposition and incorporation of isotopic and biological proxies into sediments.
