Sea-level rise and extremes in Norway

This report describes how the sea is expected to rise along the Norwegian coast towards the middle and end of this century, and further towards the year 2300. Glaciers and the Greenland and Antarctic ice sheets are losing mass and the oceans are warming, causing global sea-level rise. This represents a growing risk that coastal countries, including Norway.

Owing to vertical land uplift, Norway has long had falling or stable relative sea levels. However, results from this report show that sea-level rise is starting to push up water levels in some parts of the coast, most notably in Western and Southern Norway. Owing to global warming, Norway is transitioning from a country with on average falling or stable relative sea level, to one with rising relative sea levels.
