CS3 (2018b).
recent model-based studies, expert
assessments and national assessments
have suggested an upper bound for 21st
century global mean sea level rise in the
range of 1.5-2.5 m. Further increases by
several metres by 2300, and by many
metres by 2500, are possible if the
stabilisation goal of the Paris Agreement
is not met (EEA, 2019e).
All coastal regions in Europe have
experienced an increase in absolute
sea level but with significant regional
variation (Map 7.4). Extreme high
coastal water levels have increased
at most locations along the European
coastline. The rise in sea level relative
to land along most European coasts
is projected to be similar to the
global average, with the exception
of the northern Baltic Sea and the
northern Atlantic coast, which are
experiencing considerable land rise
as a consequence of post-glacial
rebound. The increase in sea level
and coastal flood levels is threatening
coastal ecosystems, water resources,
settlements, infrastructure and human
