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.
Global mean sea level has been rising at an average rate of approximately 1.7 mm/year over the past 100 years (measured from tide gauge observations), which is significantly larger than the rate averaged over the last several thousand years.lobal average temperature is one of the most-cited indicators of global climate change, and shows an increase of approximately 1.4Â°F since the early 20 th Century. The global surface temperature is based on air temperature data over land and sea-surface temperatures observed from ships, buoys and satellites.
