Grønland får flere og flere ældre. Ifølge Stig Andersen, leder af Center for Grønlandsforskning på Aalborg Universitetshospital, får sundhedsvæsenet sin sag for med at behandle dem. Af Helene Chéret, Dagens Medicin

For at finde forklaringer på, hvorfor grønlændernes sundhed skranter, sætter et nyt Center for Arktisk Sundhed ved Aarhus Universitet projekter i gang i Grønland. Centeret

undersøger, hvordan miljø, genetik og livsstil spiller ind på udviklingen af kræft og andre sygdomme hos inuitbefolkningen.

The Arctic Science Partnership is in the high Arctic studying polynyas. A polynya is an ice-free site in an otherwise ice-covered area. The particular polynya studied is located outside the Young Sound fjord in NE Greenland and is maintained by high winds blowing the newly formed sea ice away from the area. Not a place you would normally want to be. But for this small team of scientists studying ice and ocean processes, this is heaven.

Klimaforandringer og dermed mere skibstrafik, vil øge risikoen for indførsel af invasive arter i Arktis.

The increased sea temperature expected in 2100 will in itself mean that the potential number of species introduced with ships will increase more than sixfold in Svalbard. These are the findings of a new study with participation from Aarhus University. In consideration of the fact that the number of ships in the Arctic will also increase there is good reason to be on guard - including in Greenland.

Centre for Past Climate Studies, Department of Geoscience, together with the Arctic Research Centre are editors of a volume about the subject in the international journal "Quaternary Science Reviews.

Siden 1996 har danske forskere drevet forskningsstationen Zackenberg i Nordøstgrønland, hvor de udfører målinger på de arktiske økosystemer.

Biolog og fotograf Mads Forchhammer var med til at starte stationen op og er siden kommet der jævnligt. Blandt andet over 2 vintre i 2008 og 2012, hvor han lavede optagelserne til fotobogen "Zackenberg - on the edge of winter" der illustrerer livet blandt forskerne i et meget udfordrende arktisk miljø.

There are huge amounts of organic carbon in the soil beneath the tundra that covers the northernmost woodless areas of the planet. New research findings from Aarhus University show that the tundra may become a source of CO2 as the climate becomes warmer.

Aarhus University plays a central role in understanding the major environmental changes taking place in the Arctic. This forms part of the basis for the decision-making process for future developments of the societies of the Arctic.
