    Greenland's ice faces melting 'death sentence'

    Greenland's massive ice sheet may have melted by a record amount this year, scientists have warned.
    During this year alone, it lost enough ice to raise the average global sea level by more than a millimetre.
    Researchers say they're "astounded" by the acceleration in melting and fear for the future of cities on coasts around the world.
    One glacier in southern Greenland has thinned by as much as 100 metres since I last filmed on it back in 2004.

    Why does Greenland matter?

    Essentially because its ice sheet is seven times the area of the UK and up to 2-3km thick in places. It stores so much frozen water that if the whole thing melted, it would raise sea levels worldwide by up to 7m.
    No one is suggesting that could happen for hundreds or even thousands of years but even a small increase in the rate of melting in coming decades could threaten millions of people living in low-lying areas.
    Bangladesh, Florida, and eastern England are among many areas known to be particularly vulnerable to rises in sea level over the course of the century.
    And although the island of Greenland is remote, stretching from the north of the Atlantic high into the Arctic, its fate could have major implications for the severity of future flooding and may even alter coastlines and force communities to move inland.
