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.
But scientific research is finding that marine ecosystems can be far more sensitive to even the most modest temperature change. Global warming caused by human activities that emit heat-trapping carbon dioxide has raised the average global temperature by about 1Â°F (0.6Â°C) over the past century. In the oceans, this change has only been about 0.18Â°F (0.1Â°C). This warming has occurred from the surface to a depth of about 2,300 feet (700 meters), where most marine life thrives. Perhaps the ocean organism most vulnerable to temperature change is coral.
