- Anything on the scale of a few hundred years is far too fast for plate
- tectonics to have any effect. Global sea level changes seem to be almost
- entirely the result of the presence/absence/changing volume of the glaciers,
- and in particular the continental scale glaciers such as Greenland and
- Antarctica. If my memory serves me, during the late Wisconsin (a time period)
- glacial maximum, the sea level was >100 meters lower than at present due to the
- volume of H2O locked up in the continental ice sheets of North America and
- Europe (the Europeans call this the Wurm period i believe, even though I think
- my spelling is wrong).
