Physics of Ice, Climate and Earth
The section for the Physics of Ice, Climate and Earth at the Niels Bohr Institute studies the elements of the Earth system – the atmosphere, oceans, ice sheets and glaciers, sea ice, and the solid Earth itself – and the interactions between them.
We have a world-leading role in the drilling of ice cores from the Greenland and Antarctic ice sheets, analyse the ice samples in our laboratories, and interpret the data together with results from computer models of all parts of the climate system, including general circulation models and models of ice flow.
We also work with theoretical aspects of meteorology, oceanography and complex system dynamics to understand both gradual and abrupt climatic changes of the past, present, and future. We study the physics of the solid Earth with seismic data, gravity and magnetic observations from satellites, inverse method theory and numerical modelling.
The Niels Bohr Institute’s section for the Physics of Ice, Climate and Earth (PICE) was created in 2019 by merging the former sections for Ice and Climate and Climate and Computational Geophysics.
It includes the Ice and Climat Research Group which in 2007-2017 was a centre of excellence funded by the Danish National Research Foundation, and which was also a focal point for a large number of independently funded research projects. The Centre for Ice and Climate builds on a long tradition that goes back to the birth of ice-core palaeoclimatology and the centre home page contains extensive data and publication collections that are still maintained.
The Niels Bohr institute has many M.Sc. and PhD students. The students are closely attached to the research groups and supervisor, and have many social activities for International and Danish students.

The research in the section for Ice, Climate and Earth deals with all elements of the climate system and the processes and feedbacks that connect them.
We perform field work to obtain samples and data and employ a combination of state-of-the-art measurements, computational methods, and novel theoretical approaches to improve our knowledge of past, present, and future climate. Choose a topic below to learn more.
Climate change: past, present & future
Climate models and ice core data improves our ability to predict future climate change.
Drilling and analysing ice cores
A significant part of the processing and analysing of the ice cores takes place in the field.
Flow of ice
Ice flow models are important tools for dating and for understanding ice dynamics.
Ice on other planets and moons
Life as we know it on Earth is closely linked to the presence of water. How is the presence of water in the Solar System?
Meteorology: The dynamical atmosphere
We study and develop models of the physical processes of the atmosphere, e.g. for numerical weather prediction. Other topics are air quality and pollution.
The research is focused on ocean processes that contribute to water mass transformations and the large climate fluctuations observed in the last million years.
Reconstructing past atmospheres
Water molecules, air bubbles, and tiny amounts of impurities in ice cores help us to reconstruct ancient climate conditions.
Solid Earth Physics and geostatistics
We study the solid Earth using field experiments, theory and numerical modelling based on seismic data and satellite measurements of gravity and magnetism.
Stratigraphy and dating
Ice cores are dated by annual layer counting and by applying computer models.
Computing at Danish Center for Climate Computing
The DC3 (Danish Center for Climate Computing) provides High Performance Computing (HPC) resources to scientists and students at the Physics of Ice, Climate, and Earth section.DC3 web-page.
The group uses methods from theoretical physics to describe and model atmospheric processes. The aim is to capture emergent aspects, e.g. self-organization, that originate from small scales but can impact on larger scales.
Centre for Ice and Climate was a Danish National Research Foundation centre of excellence from April 1st, 2007, to March 31st, 2017, and is now a part of the section for the Physics of Ice, Climate and Earth.
The diverse research in the Ice, Climate and Geophysics section is funded by the Niels Bohr Institute and a number of grants from both public and private foundations in Denmark and abroad.
TiPES aims to understand the tipping points of the climate system 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 system theory, as well as decision theory.
The project, which is supported by the Carlsberg Foundation, provides new knowledge about the mechanisms of the abrupt climate changes of the past based on ice-core data and new climate model results.
Master thesis projects at PICE
Do your Master Thesis Project at the section of Ice Climate and Earth. We work on analyzing past climate variability by means of ice core analysis.
As a Master student at the section, you will work in active and dynamic groups on a real research project. We offer both 6-month and 12-month projects. Below you can find thesis project suggestions. You are also very welcome to come by the centre and ask the researchers for further options or present your own idea that we can develop together.
High school classes and other groups can request a visit at the section. The most common topic is climate change with focus on ice-core science, but other topics are possible.
Web pages, movies, popular science papers about our research
Under Research you will find A lot of the section’s ice-core-based climate research described for non-specialists. You can also find information about our available high-school projects “studieretningsprojekter”. Finally, we provide a list of popular science texts in Danish.
Willi Dansgaard founded the world’s first research group focused on climate research based on ice-core analysis (read a short version of the background story here).
After his retirement in 1992, Willi Dansgaard wrote an autobiograhic book in Danish, Grønland i Istid og Nutid (Rhodos, 2000, ISBN 8772457996). Later, he compiled an English version, Frozen Annals, which focuses more on the scientific part of the story. The book can be downloaded here as a pdf file.
The personal profile page of each scientists in the section (find the staff list below) features a personal list of published scientific papers.
