What causes glaciers to melt from below?

Today’s Video of the Day from NASA Earth Observatory explains why many of Greenland’s glaciers are melting from below.
Scientists with the Oceans Melting Greenland (OMG) mission have been surveying more than 200 glaciers over the past five years.
The researchers found that glaciers in deep fjords come into contact with more warm water, which causes undercutting. During this process, warm seawater melts the base of the glacier and causes the ice to break apart.
