Hello Dale,

Worse case estimate: If all the ice on Antartica and Greenland melts, the 
average sea level rises by 67 meters.

Mind you: "average". It would not rise by the same amount everywhere on earth. 
Near Geenland and Antarctica, it may even fall a bit. That is because of 
gravitational attraction on the ocean water by the ice masses, sea level is 
presently higher thers that it would be without the ice. When the ice goes, 
that extra water flows away fom the region.

The Neterhelands is a bit better off than the 67 meters average. It is in the 
region near enough to Greenland for the gravitational effect to be in favour. 
Still, a 50 meter sea rise would be disastrous. All of The Netherlands would be 
flooded, except for a small part in the South East. Same for Belgium, Denmark 
the Northern part of Germany and the Baltic States.


Cheers, Michiel
