NOTE: The melting of the West Antarctic ice
sheet could raise sea level as much as 15 feet. By July,
1998, the stability of the West Antarctic ice sheet was
in question,because the hinge line of the Pine Island
Glacier (the 'tongue' which begins to float) had been
retreating 3/4 mile each year since 1992. Glacier
movements can be erratic, so these changes might not be a
trend. Time will tell.
