With the interdisciplinary Arctic Research Centre and a wide-ranging international collaboration, Aarhus University plays a central role in investigating the major environmental changes taking place in the Arctic.

At the end of September, researchers from institutions in Denmark, the Faroe Islands and Greenland will meet with authorities connected with the Arctic region. The meeting is the start of joint Danish efforts in Arctic research and education initiated by the University of Copenhagen and Aarhus University.

Joint Nordic Initiative on Arctic Research. Responsible Development of the Arctic: Opportunities and Challenges - Pathways to Action

Forholdene omkring Arktis har i de senere år tiltrukket megen opmærksomhed, blandt andet i forhold til klimaforandringer, potentielle råstoffer, nye sejlruter mv. Polarsekretariatet skal være med til at skabe bedre overblik over polarforskningsaktiviteterne

Nogle miljøgifte er mere skadelige i et koldt klima end i et varmt, fordi de påvirker temperaturfølsomheden hos visse organismer. Nu har forskere fra tre danske universiteter sammen påvist hvordan. Det kan give mere præcise risikovurderinger af forurening, navnlig i Arktis.

Havfugle kolonierne i Nordatlanten skrumper. I løbet af de sidste 10 år er ynglesuccesen for bl.a. Lunden og den Arktiske Terne faldet drastisk, og det er især tydeligt på Island, der ellers plejer at være havfuglenes Serengeti.
