Sea levels will not stop rising: Nasa

The village of Ilulissat, in Greenland, is seen near icebergs that broke off from the Jakobshavn Glacier on July 24, 2013. A sea level rise of 91.44cm has likely been "locked in" by warming that's already happened, but some predict that's just the tip of the problem.

A glacier that has just shed a massive chunk of ice alone holds back enough ice for a significant sea level rise.
