An increase in atmospheric temperature can cause land ice to melt faster than it builds up, and also causes the sea temperature to rise and therefore increase in volume. The consequence is a global rise in sea level.
In Sweden the sea level is affected by land rise. The following figure has been adjusted for land rise to show how much the sea level has actually risen. At many locations in Sweden where the land rise is quite large, such as along the coast of Västerbotten, the sea level rise is not noticeable at all, while the coast of Götaland will experience increasing sea levels.
