Natural environment and ecosystems

Changes in temperature, precipitation, snow and ice conditions have a direct impact on the natural environment and ecosystems. Swedish glaciers may disappear as well as the small areas of permafrost. The Baltic Sea, Skagerrak Sea and Kattegat Sea environment is also closely linked to the climate. 

Among the tangible effects on climate are changing climate zones, lengthening growing season, improved conditions for invasive species and potential elimination of current species, shrinking kalfjäll areas (Swedish alpine region), changing ice conditions as well as changes in salinity and oxygen concentrations in the Baltic Sea.

Increasing precipitation is expected to increase discharge, leading to higher levels of humus, nutrients and pollutants into lakes and streams. Pollution and eutrophication of the Baltic Sea is primarily due to human activities, but is also affected by runoff from land. The Baltic Sea environment is also affected by changing water temperatures as well as by changes in salinity due partly to reduced recovery of salt water through Öresund and the Strait and partly to increased rainfall.
