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.
Economic impacts are expected to vary regionally. For a medium increase in global mean temperature (2-3 Â°C of warming, relative to the average temperature between 1990â2000), market sectors in low-latitude and less-developed areas might experience net costs due to climate change.rom 1961 to 2003, the global ocean temperature has risen by 0.10 Â°C from the surface to a depth of 700 m. There is variability both year-to-year and over longer time scales, with global ocean heat content observations showing high rates of warming for 1991â2003, but some cooling from 2003 to 2007.
