The northern summit of Kebnekaise now higher than the southern summit due to a warmer climate

The annual measurements of Kebnekaise southern summit were conducted on the 3rd of September by Tarfala researcher station. The summit measured 2095,6 meter and is thereby 1,2 meters lower than the northern summit.
The highest part of the northern summit consists of solid ground and is thereby stable, whereas the southern summit is a glacier and varies in height during the year. The measurements are done every year when the melting period is over. When it starts snowing again the southern summit will surpass the northern summit again.
The southern summit is becoming lower and lower due to a warmer climate and this year’s measurements are the lowest ever recorded. During the past 50 years the height of this glacier has decreased with 24 meters.

Biodiversity and the role of mycorrhiza is undoubtedly of major significance for ecosystem processes such as carbon sequestration and soil nitrogen and organic matter dynamics. Despite their importance, it is poorly understood how and to what extent certain features of biodiversity are linked to ecosystem processes.
In a study lead by Robert G. Björk at the Univeristy of Gothenburg, they aims to improve our understanding of the coupling between plants and microbial diversity and to what extent changes in plant-soil biodiversity affect carbon and nitrogen dynamics in the ecosystem.
