North Atlantic Sea Level Variations

Sea Level trends are often studied as a direct effect of climate change, and considered an indicator of the global warming. Although a global Sea Level rise over the last decades is a well established fact, when we come to study regional variations some effort has to be paid in order to understand whether such trends are part of a longer cycle. In particular, relatively short time-span available from altimetry, combined with regional phenomenon influence, could lead to misleading conclusions. In order to illustrate this idea we have studied the North Atlantic sea level variations and how these are influenced by regional fenomena.
