GEOMAR is looking for candidates with a strong interest in Earth system modelling and model assessment. The research project will focus on the selection of indicators and development of metrics to assess a number of climate engineering ideas (such as afforestation, ocean alkalinisation, solar radiation management,…) in the context of mitigation. Tools will be developed and tested on the basis of model simulations of various climate engineering scenarios employing new and already existing runs of intermediate complexity (UVic) and complex Earth system (MPI-ESM) models. Metric development will account for model uncertainties (e.g. by analysing perturbed parameter ensembles) and include collaboration with scientists from other disciplines engaged in the Priority Program, such as social sciences, international law and ethics, and some readiness to engage in interdisciplinary work is required.
