The Niels Bohr Institute at the University of Copenhagen invites applications for three postdoctoral positions as part of an ambitious EU-funded project to improve climate projections by studying past climate mechanisms. The roles focus on various aspects of paleoclimate research, including the variability of the terrestrial cryosphere using Greenland ice core data, sea ice variability in polar oceans, and transitions in the Atlantic Meridional Overturning Circulation (AMOC). Successful candidates will have a PhD in relevant fields such as Physics, Geophysics, or Climate Science, with experience in ice core analysis techniques (preferred), and a strong interest in climate science. The positions offer a stimulating academic environment with opportunities for independent research, collaboration, and fieldwork.
