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 and climate system – the atmosphere, oceans, ice sheets and glaciers, sea ice, and the solid Earth itself – and the interactions between them.

Visit us
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.

Please fill in the form in Danish or write an e-mail to the section secretary at

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.

Frozen Annals

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). It is available for download here (note the file size: ~180 MB) 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 or viewed online here (opens in a new window)
