Palaeo Environments, Ice Sheets and Climate Change team
Our ambition
is to improve understanding of the mechanisms of past change in ice sheets, oceans and global climate. Our aim is to reduce uncertainty in predictions of future climate and sea level change, informing Government strategy for mitigating against the risks of these changes. We specialise in providing detailed past and contemporary records of climate and environmental change from high latitude regions.
Team priorities
Science
To develop our understanding of the past response of polar ice sheets and ice shelves to environmental changes. Our aim is to improve forecasts of global sea levels and ice mass loss by providing data against which ice sheet models can be tested.
To investigate the history of the Southern Hemisphere Westerly Winds and their role in ice sheet dynamics and the global CO2 budget. We aim to detect when human impacts exceed the natural ranges of variability in the Earth system by studying climate signals in marine and terrestrial sediments.
To study changes in the production and export of Antarctic Bottom Water, the circulation of Southern Ocean deep- and bottom-water masses, and the role of sea ice, melt water and biological productivity in controlling past, and future, climate changes.
To improve understanding of the transition between greenhouse and icehouse climate states and the wider impact of global climate changes on the environment. We will study the physical environment, terrestrial and marine palaeobiology and community analysis from the geological past.
