| One of the climate changes is an
increase in the sea level, which will increase shore erosion.
During the past century, the sea level globally has risen on
average by 15-20 cm, of which 2-5 cm is due to melting of glaciers.
A further 2-7 cm is due to expansion of ocean water, since an
increase in ocean water temperature causes an increase in water
volume. The water level in the Baltic Sea at the Daugavgrīva
Observation Station has risen during the past 100 years by 22 cm.
