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 warming and climate change are terms for the observed century-scale rise in the average temperature of the Earth's climate system and its related effects.Multiple lines of scientific evidence show that the climate system is warming.Although the increase of near-surface atmospheric temperature is the measure of global warming often reported in the popular press, most of the additional energy stored in the climate system since 1970 has gone into ocean warming.limate model projections summarized in the report indicated that during the 21st century the global surface temperature is likely to rise a further 0.3 to 1.7 Â°C (0.5 to 3.1 Â°F) for their lowest emissions scenario using stringent mitigation and 2.6 to 4.8 Â°C (4.7 to 8.6 Â°F) for their highest.
