Average sea levels have swelled over 23 cm since 1850. Every year the sea rises on average 3.2 mm.
The change of sea levels is linked to:
Glaciers are a natural resource of fresh water. Storing water in the winter and doling it out in the summer as the ice slowly melts. People all over the world use the meltwater that glaciers produce. A significant part of river flow comes from melting glaciers and provide water during dry spells .
