Regional and global sea level change – Causes:
Sea level variability and changes are part of past and ongoing climate variability and change that affect a large part of the civilization living near coastal areas. Past changes, after the last glacial maximum, point at a large potential for sea level change.
Different mechanisms connected to long term changes in the past associated with postglacial melting and ongoing climate change involve different factors contributing to changes in sea level. On regional scale, sea level changes related to decadal climate variability are likely to be of the same order as the predicted global change for the current century.
