Natural environment

Climate change is expected to lead to changes in biodiversity and ecosystems.

Climate change will have an impact on biodiversity both directly through changes to temperature and precipitation and indirectly through changes in terms of land use. Ecosystems with a rich biodiversity are better able to resist disruption. 

When the climate becomes warmer, the climate zones and vegetation zones move northwards. There is an impact on plants' and animals' reproduction, the distribution and size of their populations and the incidence of pests. Uncommon species may disappear, while new species may become established.

Mountainous areas are particularly sensitive to climate change. The size of Sweden's alpine areas is expected to decrease sharply when the tree line rises. 

Changes to the conditions in the Baltic Sea will result in major changes to its biodiversity. The temperature in the Baltic Sea is increasing and the extent of the sea ice is decreasing drastically. An increase in the global sea level will entail a rise in the level of the Baltic Sea. It is also expected that the salinity of the Baltic Sea might change as a result of changes to wind conditions and the flow of fresh water from increases precipitation and drainage from watercourses.
