They are trying to understand the climate change at the Arctic

Climate change is the strongest around the North and South poles. When the rest of the world gets a temperature increase of 1 degree, one can expect much greater changes in these areas. What happens at the poles doesn’t stay at the poles. Changes in the weather here will affect the entire planet. Meet the researchers who in different ways try to understand what is happening: Michael Tjernström, Stockholm University, Jan Karlsson, Umeå University and Sebastiaan Swart at the University of Gothenburg.

Fingerprints of change: Abisko plants and phenology citizen science

Abisko Plant and Phenology iNaturalist poster 20180711.jpg

Abisko plants and phenology (fjällkalendern) aims at collecting species distributions and phenology data for the Abisko region (focused in and around Abisko National Park). This project is part of our larger efforts to identify the fingerprints of environmental change in Abisko. We have over 100 years of plant distribution and phenology data, plus weather data (1913 to present), from researchers at the Abisko Scientific Research Station. This provides a unique time machine to allow us to quantify the change to the plant communities of this region perched on the edge of the Arctic.

Temperature change affects temperate mountain ecosystems globally

The warmer climate that is expected over the next 80 years could lead to major disruptions in ecosystems of high mountain landscapes, for example by altered balance between nitrogen and phosphorus in the soil. The results in a new study are presented by an international team of researchers led by SLU in Nature. Maja Sundqvist, active researcher in the Climate Impact Research Centre (CIRC), Umeå University, participated in the study.

Arctic research

Swedish and United States partnerships in science and the polar regions have a long history. This week the United States Ambassador Azita Raji and her team Michael J. Layne and Kristy Plan visited the Abisko Scientific Research Station to experience the Arctic in winter in Sweden first-hand.

Climate is no ubiquitous explanation of fluctuations in reindeer numbers

Exploitation of natural resources, such as forestry or gas and oil extraction, and management practices may have faster and greater impacts on reindeer populations than does climate change, a study finds. However, climate change should not be forgotten or underestimated, since reindeer are adapted to cold temperatures and therefore susceptible to temperature increases.
