The Institute for Marine and Atmospheric Research invites applications for a Postdoctoral Researcher in the field of climate dynamics and earth system modelling. The successful candidate will be part of the EU-funded H2020 project 'Tipping Points of the Earth System' (TiPES), funded by the European Union’s Horizon 2020 research and innovation programme under grant agreement No 820970, and will work on Earth System Modelling of the paleoclimate.
Several subsystems of the earth may respond abruptly at critical future levels of anthropogenic forcing, which have been associated with tipping points (TPs). It is paramount to identify safe operating spaces in terms of these critical forcing levels, in order to prevent harmful transitions to alternative, undesirable states of the earth and its subsystems. The mechanisms leading to abrupt climate transitions are only partly understood, and reliable warning signals for forthcoming transitions are urgently needed. TiPES addresses these questions in a joint effort of 18 European institutions, combining paleoclimatology, time series analysis, earth system modelling of past and future climates, applied mathematics and dynamical systems theory, as well as decision theory.
The successful candidate will be part of work package WP2 of the TiPES project, which focuses on stability in past warm climates. Specifically, the candidate will be expected to study the interaction of changes in forcing conditions (e.g. CO2, continental geometry) and feedbacks in the climate system responsible for climate conditions and transitions during the Cenozoic period using time-slice modelling with an earth system model (CESM). The candidate is expected to participate in coordinated model intercomparison projects such as DeepMIP. The aim is to characterise the ability of several IPCC type models to simulate the background climate and the variability and stability of these past warm climates.
