Overall, land masses have different tendencies to go up or down,
sometimes associated with (they think) the fact that old, old glaciers
from the ice ages aren't there anymore to weigh those land masses
down. Scandinavia is one example. One of the scary reasons to pay
attention to ocean warming is that much is really cold (like in the
30's and low 40's in Fahrenheit). If all that ocean water warms just a
few degrees, it will expand, and thus the level will go up. Somebody
ought to have the calculated data how much up that up is.

Start with a calculation of how much energy it would take to warm the
upper 50 feet of ocean by 1 degree F. I would be very surprised if all
the energy released by human activity in the last 50 years, if it all
went directly into heating the oceans, would be enough to accomplish that.
