That's a good question. It's hard to measure sea level. What do you compare it to in order to measure it?

Different areas of land rise and fall at different rates as well. There can be no definitive measurement from 'one point' of dry land due to natural geologic processes. Not to mention natural erosion which is rather extreme along many parts of worldwide seashores.

Exactly.

However, Al Gore seems to have the definitive answer. Which is enough to convince me it's nonsense.

I live and work here in Beaufort county and spend a lot of time on the water. I have noticed dead trees along the New River and places where the marsh seems to be receding. However, I feel that land and water levels DO rise and fall, sometimes dramatically. The islands around here have been eroding for centuries. Just look at Hunting Island - I've seen inlets opened by "normal" storms and most of the old campground now lies offshore.

The sandbar in the foreground was dry land not long ago;
and the marshy spot halfway down the beach is now open to the sea again.
