Climate change impacts in Sweden
- In several northern hemisphere mountain systems, treelines have markedly shifted to higher elevations during the 20th century such as in the Scandes [18.104.22.168].
- Northward expansion of Tick (Ixodes ricinus) due to increased temperature, between 1982-1996 [22.214.171.124].
- An increase in Tick-born encephalitis since the mid-1980s is consistent with milder climate in this period, but other explanations cannot be ruled [126.96.36.199] English Holly (Ilex aquifolium) poleward shift of northern margin due to increasing winter temperatures [188.8.131.52].
- Disappearance of some types of wetlands (palsa mires) in Lapland; increased species richness and frequency at altitudinal margin of plant life [Table 12.1].
- Arctic and sub-arctic ecosystems (particularly ombrotrophic bog communities; a form of wetland) above permafrost were considered likely to be most vulnerable to climatic changes, since impacts may turn arctic regions from a net carbon sink to a net source [4.4.6].
- Some crops that currently grow mostly in S. Europe (e.g. maize, sunflower and soybeans) will become more suitable further north or at higher altitude areas in the south. Projections for a range of scenarios show a 30 to 50% increase in suitable area for grain maize production in southern Sweden by the end of the 21st century [184.108.40.206].
- WWF Sweden has drafted a vulnerability assessment proposal for the Baltic Sea Ecoregion and is currently working with local stakeholders and governments on integrating adaptation strategies in the region.
