-
- There is today, locked up in the ice caps of Antarctica and
- Greenland sufficient ice, should it melt, to raise the sea
- level by 200 feet (approx) above current levels. The average
- thickness of these ice caps is about 5000 feet and they cover
- about 4% of the Earths surface.
-
- The North Polar cap, being floating ice, wouldn't affect sea
- levels at all.

- >>> villages submerged
- On the other hand, Pevensey in England, where William of Normandy
- landed in 1066, was a coastal fortress originally built by the
- Romans. When William landed he tied his ships at the foot of the
- castle and camped prior to moving north to fight the Battle of
- Hastings (which was neither called Battle of Hastings - forget real
- name - nor was at Hastings, today the place is called Battle).
-
- Pevensey is, today, 7 miles inland. This has little to do with
- rising sea levels, however, as it is due to the tilting of the
- island (Great Britain). It is not enough to paint a line on a
- cliff to see if the sea level rises or falls (over a few centuries),
- it is also necessary to determine that the cliff itself is not
- rising or falling.
