Paleoclimate variability and dynamics

In the paleoclimate realm, the EEES Earth system modelling group focuses primarily on problems involving long-timescale Earth system dynamics beyond the reach of high-resolution modelling, but the group also employs higher-resolution models to address specific research questions.  Long-timescale environment, Earth system and ecosystem changes in Earth history are addressed through the development and application of Earth system models of intermediate complexity (EMICs), notably GENIE and PLASIM, and statistical models of Earth system processes. The group works closely with observationalists, and with other modellers, within the School as well as outside the OU and the UK. The primary objective is to use modelling to improve understanding of the mechanisms and processes underlying the palaeoclimate proxy record of past Earth system changes, and the origins and basis of variability and resilience of the Earth system in the past. Ultimately, the aim is to transform this improved knowledge of the past into a deeper understanding of the present and future states of the Earth system. 

 

Particular areas in which the group is working or has worked include the evolution of human society through the Holocene under the influence of climate change and societal development, in connection with the SESHAT historical database project; Pleistocene glacial-interglacial (GIG) cycles and the GIG CO2 problem; ice-sheet dynamics and probabilistic constraints on sealevel rise from ice-sheet melting; the evolution of biodiversity; the climate effects of terrestrial methane emissions in the Eocene and past warm climate states including the Eocene and related ocean deoxygenation events.
