How fast is the sea level rising?

The rising sea level is perhaps the greatest threat to mankind.  The rising sea level is already affecting our lives in may ways - more severe storms, drought, heat wave and floods are just some of the adverse impact. 

In a study published in 2002 in Science, a peer-reviewed journal, scientists estimated that the melting glaciers in Alaska alone contributed around 52 cubic kilometre of fresh water each year (Arendt et al, 2002). It translates into a rise in sea level of 0.14 ± 0.04 mm/year. The study was conducted using airborne laser altimetry to estimate the volume change of 67 glaciers from mid-1950s to mid-1990s.
