Scientists say the melting of the massive ice sheet on Greenland --
which has been stable for thousands of years -- could increase sea
levels by as much as 7 metres (23 feet). Such a rise would inundate
vast areas of land, including cities at sea level, such as London.
Some densely populated regions, such as Bangladesh, may disappear.

For the ice sheet to begin melting, ambient temperatures around
Greenland would need to rise more than 3 degrees Celsius, Jonathan
Gregory, a climate scientist with the Met Office Hadley Centre and
the University of Reading, said. The concentrations of man-made
greenhouse gases would probably reach levels that would trigger the
melting by about the middle of the century.
