How come you have such a dinky little profile?
BTTT for later reading.
He was so precise in his anaysis of the plate tectonics and ice age effects that he could be accurate to a millimeter? Suuuure.
I learned a very important scientific technique in high school physics and chemistry classes. If you know the results you need, you can adjust the data just enough to give you those results. In my school days, this technique served to get a me better grade. For this "scientist", it is to get the respect of his peers (i.e. publish or perish), and continued research grants (i.e. free research expeditions to Italy).
You nailed it.
Venice is built on deep alluvial sediments (i.e., not bedrock). It is sinking because the sediments are naturally compacting under their own weight. The same thing is happening to our Mississippi delta.
There's something wrong with this. The land would have had to have FALLEN by 1.22 meters, not risen, for his figures to be correct.
"...Has anyone noticed the Tidal Basin in DC rearing up to swallow the national monuments in the last century ?..."
I live downstream from DC along the Chesapeake. Broomes Island IS being swallowed by the Patuxent River (as are some other low islands and terraces), as sea level rises. Locally, we calculate that net rise (sea level rise plus terrestrial subsidence) to be about an inch per century.
All around this area one can see the remains of old waterfront homes, built 100 years ago or more, that are now lapped by high tides.
btt
The world experts on this are the Dutch and the people of Venice.
They have noticed a slight rise in sea level over the past 200 years. A few inches.
And the seas have been rising every since the end of the ice age 18,000 and 12,000 years ago. They will continue to rise slowly until the next ice age starts, (then beachfront property will be worth nothing.)
Good for another bump.
