The Environmental Change group investigates change in the climate system, cryosphere and marine environment over the recent past, in the present, and into the future. The group employs various methods, covering palaeoecological and palaeoclimatic analytical and dating approaches, remote sensing, field surveys and numerical modelling, in order to:
- document periods of major past climate and environmental change;
- reconstruct and model glacial and ice-sheet dynamics over multiple Quaternary timescales;
- understand the effects of environmental change on contemporary terrestrial and marine environments.
Key research themes include:
- Past climate dynamics
This theme covers a diverse range of techniques to reconstruct past climate dynamics, including developing palaeoclimatic and paleaoecological records across Europe, Asia, South America, Africa, the Antarctic Peninsula and the Arctic, and quantifying global peatland carbon dynamics.
- Ice, sea level & climate change
This theme involves research into the past, present, and future dynamics of the Antarctic & Greenland ice sheets, using numerical modelling, satellite and airborne remote sensing and marine geophysics. The theme also focuses on the reconstruction of the Patagonia Ice Sheet and tropical glaciers using Cosmogenic Nuclide dating.
- Marine carbonate production and cycling
This theme examines the impact of environmental and climatic change on marine carbonate production. Key areas of research focus on: the dynamics of coral reef growth and change, with current projects focused on the Caribbean, in the Great Barrier Reef, the central Indian Ocean, and East Africa; and the sources and the fate of marine carbonates in the context of the global marine carbon cycle.
