Paleoclimate and Climate Systems research group of the School of Earth and 
Ocean Sciences at Cardiff University, UK and in association with the Alfred 
Wegener Institute, Germany

‘Assessing the role of millennial-scale variability in glacial-interglacial 
climate change’

During the Pleistocene epoch (or at least the last 800,000 years), Earth’s 
climate has been dominated by variations both on orbital (tens to hundreds of 
thousands of years) and millennial timescales. Each of these modes of 
variability has received significant enquiry and yet each remains enigmatic in 
its underlying mechanisms. Recently however, progress has been made in 
understanding the potential interplay between millennial-scale climate 
variability (involving abrupt changes in ocean circulation and the so-called 
bipolar seesaw) and the mechanism of deglaciation (the transition from glacial 
to interglacial conditions). This project aims to provide quantitative 
information about this link in order to learn more about the mechanism of 
glacial termination. Specifically, we aim to quantitatively differentiate 
between those millennial-scale oscillations that coincide with glacial 
terminations and those that do not and to determine the precise temporal 
relationship between seesaw oscillations, glacial terminations and changes in 
orbital configuration. In so doing we aim to make progress on the following 
outstanding questions: Are bipolar seesaw oscillations a necessary feature of 
glacial terminations or merely a complicating factor? Are seesaw oscillations 
themselves sufficient to drive glacial termination or are there particular 
characteristics of terminal oscillations that promote deglaciation? What are 
the connections between varying boundary conditions (insolation, ice volume, 
atmospheric CO2 concentration) and the nature of seesaw oscillations? Is there 
an underlying orbital parameter that ultimately controls the occurrence of 
glacial terminations? The project will involve a combination of quantitative 
data analysis and the application of state-of-the-art computer models of the 
climate system.

Candidates for the post should have a PhD in natural sciences, experience in 
numerical Earth system modelling and quantitative data analysis and a strong 
interest in climate science. The project is led by Dr Stephen Barker (Cardiff 
University, UK) in close association with Dr Gregor Knorr (Alfred Wegener 
Institute, Germany) and Prof Andy Ridgwell (University of Bristol, UK). The 
post will involve extended visits to Germany for training and interaction with 
Co-I Knorr.

Informal enquires may be made to Dr Stephen Barker,

This is a full-time post and is fixed term for a period of 3 years.
Salary: £30,122 - £35,938 per annum
