Ocean and Climate Systems
The Ocean and Climate Research Group (OCS RG) works on a variety of processes and timescales within the ocean-climate system.
The Ocean and Climate Systems Research Group investigates a variety of climate change processes and consequences within the ocean-climate system.
We use field research, palaeoclimate records, numerical modelling, and policy research to investigate climate change over a range of timescales. We are interested in interactions between different components of the Earth System, and the impacts of climate change on society.
Our expertise in numerical modelling, geochemistry, policy development, and risk analysis is used to address some of the major questions about the dynamics and impacts of our changing climate system.
We aim to understand a range of causes and consequences of change in the climate system, including:
- ice sheet stability
- sea level change and coastal governance
- mechanisms of abrupt climate change
- ocean acidification
- climate risk and resilience
- weather extremes
- water resources
- interactions between climate and social behaviour.
We work on developing and utilizing a variety of numerical models at a range of scales, from modelling lakes on the surface of Antarctica’s ice shelves, to regional climate modelling, investigating climate extremes, and climate projection development. Our developments include a hydrological model for drylands in order to simulate the impact of climate change on regions prone to water scarcity, and dust emission modelling to understand the impact of mineral dust on the atmosphere and carbon cycle. Our work also influences larger Earth System Models so that the processes we are working on are accounted for in larger studies of global processes.
Geochemistry and palaeoclimate records
We generate geochemical records of past climate change to reconstruct past changes in ice sheet stability, ocean acidification and oxygenation, and climate sensitivity. We also use palaeoclimate records to understand the causes of abrupt climate change and ocean-climate interactions on a range of timescales.
Ocean and coastal governance
We develop model institutional and policy frameworks to deliver Integrated Coastal Management (ICM). We are actively involved in the development and day-to-day running of a number of international, national and more local coastal and estuary management projects, including EUROCOAST, CoastNET, Arfordir, and the local Severn Estuary Strategy.
Climate risk and resilience
In a warming climate, we expect to see changes to hazardous weather events, such as windstorms, heatwaves, fire weather, drought and flooding. Understanding how much, where and when such changes are likely to occur is critically important so that we can prepare for changes and become more resilient to climate change. Such understanding is developed by studying climate change information produced by sophisticated climate models, investigating behavioural characteristics and socio-economic factors of communities and individuals that can act to enhance or reduce their exposure to weather hazards.
We are working on the translation of climate information into multilevel decision support for social adaptation, policy development and resilience to water scarcity in drylands of East Africa. We are also studying groundwater recharge processes in global drylands and their quantification and sensitivities to environmental change. We also investigate the intersection of water, ecosystems, society and technologies, focusing on three main themes:
- hydro-socio-ecological systems under change
- resilience and environmental hazard
- innovative data technologies for the environment and development.
Climate and society
Our research embodies the interaction between social-economic activities and natural systems. We are broadly interested in exploring how human behaviour affects the natural environment, and in examining how policy can lead to consumer behaviour change that improves sustainability. Projects include the effect of climate change and air pollution on human activities such as driving and tourism, as well as the effectiveness of environmental and energy policies at the micro-level.
