According to State of the Climate 2013, global average sea level 2013 was 1.5 inches (38 mm) above the 1993-2010 average, the highest yearly average in the satellite record (since 1993), and sea level continued rising at a rate of one-eighth of an inch (3.2 mm) per year.atellite altimeter data gathered from 1993 to 2003 indicate that the rate of global average sea level rise increased to 3.1 mm per year, or about one and a quarter inches per decade.
For example, over the past 100 years, the rate of sea level rise varied from about an increase of 0.36 inches (9.1 mm) per year along the Louisiana Coast (due to land sinking), to a drop of a few inches per decade in parts of Alaska (due to post-glacial rebound).
