I'm not too sure what scientific conclusions may be drawn from a single data point. Staying in the Mediterranean area, I recall the plain between the site of Troy and the beach where the Greeks landed is a mile or more wider then in ancient times. Further the area around Alexandria that held the palace of Cleopatra is totally submerged now, and has been for centuries. The Mediterranean seems to have been active for a long longer then just 100 years.
Has anyone noticed the Tidal Basin in DC rearing up to swallow the national monuments in the last century ?
Not since Wilbur Mills and Fanne Foxe were fished out.
Troy was located on the hill of Hisarlik, which in the Bronze Age overlooked a substantial bay. This provided an excellent anchorage at the mouth of the Dardennelles and was thus a natural site for a substantial town. The bay, however, silted up in late antiquity, which is the primary reason the site of Troy became problematic. With modern mapping techniques to identify the Bronze Age shoreline, the site jumps right out at you.
Has anyone noticed the Tidal Basin in DC rearing up to swallow the national monuments in the last century ?Well said. There are those who believe that when erosion (from the waves which hit the beach continuously) bring down a seaside home, or a lighthouse, that it's a sign of sealevel rise due to global warming. Those who believe that are stone-cold stupid.
National Geographic published an interesting series of maps a few months ago that showed how there has actually been a lot of filling in since the Civil War and water originally came much closer to the White House.
I have seen the Washington Monument and Jefferson and Lincoln Memorials surrounded by water, but those were hurricane related Potomac floods.
"...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.
