Postdoc, climate modeling/paleoclimatology - Stockholm, Sweden

A two-year Postdoctoral Fellow in Climate modeling/paleoclimatology is on offer at the Department of Geological Sciences, Stockholm University, Sweden.

Logistics

This position is part of an interdisciplinary project that involves Agatha de Boer at Stockholm University, Torben Koenigk, climate modeler at the Swedish Meteorological and Hydrological Institiute (SMHI), and Helen Coxall, paleoceanographer at Stockholm University's Department of Geological Sciences.

Description

The successful candidate will work on understanding the Arctic ocean circulation and cryosphere during the Last Interglacial period, using relatively high resolution coupled climate modelling (with EC-Earth).

The Arctic is warming twice as fast as the rest of the world, in large because of the positive feedback of the sea-ice albedo. Adaption to sea-level rise and anticipation of the impacts on Arctic and global ocean circulation is hindered by uncertainty in the contribution from the shrinking Greenland ice-sheet (GIS).

To gain a better understanding of the stability of the GIS and the Arctic sea-ice, scientists have turned to the Last Interglacial (LIG) as the last period significantly warmer than today. While forcing mechanisms for the LIG and modern/future warmth are different, i.e. the LIG was forced by different solar insolation, compared to higher greenhouse gas concentrations in the future, important lessons can be gained from understanding the process and impacts of warming on Arctic systems.

The problem is that, despite significant attention in the past, current data and models paint a conflicting picture of the LIG Arctic cryosphere (both the sea ice and GIS), implying major gaps in our understanding of the physical process at play.

This postdoctoral researcher will work as part of an interdisciplinary team of experts on paleoclimate modeling, paleoclimate data, and future climate modeling. The project’s primary goal is to simulate the LIG in the adapted EC-Earth global climate model at a ¼° ocean resolution, which is state of the art in paleoclimate modeling.

Unlike previous studies, which typically compare the LIG climate to the pre-industrial climate, the LIG mean state and variability will be directly compared to a future greenhouse world of comparable warmth. The postdoctoral researcher will simulate the LIG climate with and without a GIS to evaluate which state fits the proxies best. For this purpose, an up-to-date synthesis of climate proxies for the LIG will be produced, including the generation (by collaborators) of nine new sea-ice records as part of this project.
