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.
Sea surface temperature increased over the 20th century and continues to rise. From 1901 through 2012, temperatures rose at an average rate of 0.13Â°F per decade. Sea surface temperatures have been higher during the past three decades than at any other time since reliable observations began in 1880.he temperature of the ocean at depth lags the Earth's atmosphere temperature by 15 days per 10 metres (33 ft), which means for locations like the Aral Sea, temperatures near its bottom reach a maximum in December and a minimum in May and June.
