2 PhD Fellow Positions (3-year) available in the field of Climate Theory at the Niels Bohr Institute

PhD Fellow Positions:

The positions are part of the CriticalEarth project – a Horizon 2020 Marie Skłodowska-Curie Actions, Innovative Training Network (ITN).

Niels Bohr Institute

We would like to encourage applications from candidates worldwide wishing to pursue a PhD degree in the field of Climate Theory with an interest in the following research areas; Earth System Modelling, complex mathematics, climate simulation, ocean-atmosphere-land-sea ice processes and tipping point behaviour.

Niels Bohr Institute's (NBI) section for the Physics of Ice, Climate and Earth (PICE), Faculty of Science at University of Copenhagen is offering two PhD Fellowships, referred to as early-stage researchers (ESR) in Climate Theory, starting between 01.03.2021 and 31.09.2021. PICE studies the elements of the Earth and climate system – the atmosphere, oceans, ice sheets, sea ice, solid Earth, and the interactions between them.

The positions are posted as part of the exciting CriticalEarth project - “Multiscale Critical Transitions in the Earth System - funded through the Horizon 2020 Marie Skłodowska-Curie Actions programme under Grant number 956170.

You will join a network of 15 PhD Fellows (ESRs), trained to research new methods for assessing the mechanisms and associated risks of critical transitions in the climate. The focus will be on investigating how complex mathematics can be used to predict and avoid irreversible climate change. The position will offer you an excellent background, working within a strong, cross-disciplinary network among leading Universities and research institutions across Europe and with contacts to industry, governmental- and non-governmental institutions.

Project Descriptions

ESR1: Project Title: Tipping in the past and future climate

Principal supervisor: Associate Professor Peter Ditlevsen,based at PICE, NBI in Denmark.

This PhD project will simulate climate change during the past glacial cycle. The project will use a hierarchy of models to investigate different types of possible climate transitions that the Earth system has experienced during the last glacial cycle. The project will use a suite of Earth System Model (ESM) complexity, as well as a theoretical based dynamical systems approach to determining the nature of the transitional behaviour present in the full range of model complexity.

Secondments for at least 6 months at Complutense University of Madrid (Spain) and University of Exeter (UK) will provide training in ice sheet model interpretation and theoretical development of b-, n- and r-tipping exhibited in the climate model simulations.  

ESR2: Project Title: Climate response to greenhouse gas forcing

Principal supervisor: Associate Professor Peter Ditlevsen,based at PICE, NBI in Denmark.

The aim of this PhD project is to identify accelerated climate response to greenhouse gas forcing in observations and climate models. The relationship between forcing and response will be investigated. In the paleoclimate the forcing is taken to be determined by the astronomically driven changes in insolation, while the response is the climatic record. In present days’ climate and future projections, the forcing is the measured and prescribed greenhouse gas concentrations, while the response is the observed climate and the climate model projections. The CMIP5 and CMIP6 will be analysed and compared with observations in order to detect accelerated (non-linear) climate response to the greenhouse gas forcing.

A Secondment with Danish Meteorological Institute (Denmark) will provide observational - and CMIP6 archive data. FUB will provide methodology to quantify the response to forcing using dynamical systems.

Application deadline: February 18, 2021
