Yes.
If global warming would be the case, all the seas would rise the same.
Since it is a localized effect, then it must be caused by sinking the land in those areas!
There is considerable beach erosion in some areas because rivers have been dammed for flood control, reservoirs, and siphoned off for use by cities and for agriculture. The rivers no longer spew sand and sediment when they empty into the sea to be carried by longshore currents and deposited on the beaches as they once did. Instead, the longshore currents scour the beaches of sand once deposited there, with precious little to replace e it.
Dredging of shipping lanes adds to beach erosion. In addition, the removal of dunes, sea oats, etc. took away the “natural defenses” of beaches against storms, etc. The problem is manmade, but it isn’t global warming.
Right - absurd! When one of my children raised the point about seas rising somewhere around the world, I asked them how much they rose near us - because we are near a river connected to the ocean (with salt water at high tide). Of course, the answer is 0 - not one or two inches over the past decades, but 0.
sinking land or ask them when was the last time they shelled out the money for beach recovery projects that many other beach strand communities shell out for.
