It hardly seems possible when seen from the air. The lake is so small
compared to the whole state.
Volumes, as oppposed to areas, can be very deceptive to the human eye
and mind.

The volume of ice on greenland would not seem to possibly be enough to
raise the oceans 2-3 feet. And yet it is. Things are quite commonly
not what they seem.

Add: John Coleman owns the weather channel. While this gives him a
forum from which to sound off, it is *hardly "bona fides" for an
informed opinion on climate change.

The USGS says a complete melt of the Greenland ice sheet would raise
sea level 6.5 meters or 21 feet - http://pubs.usgs.gov/fs/fs2-00/ If
that melted, there would be enough ice melt elsewhere to double
that.

Of course, the temperature rise that would do that would cause the
ocean waters to expand enough to raise it another 200 feet or so
putting 80% of the homes in the world underwater.

That much ice melt would expose darker oceans and ground surface so
more of the sun's heat would be absorbed instead of reflected back to
space.

Like most of the climate variables, there's always pesky multiplier
effects which makes exact predictions extremely difficult.
