Overall, land masses have different tendencies to go up or down,

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.

If the earth absorbs more energy from the sun, whatever the mechanism(s),
those oceans were in 2001 already thought to expand to the tune of a rise
in sealevel by 2100 of between 11 and 43 cm, solely due to water
expansion in the oceans. By that time my teeth won't hurt me anymore,
but still.
