Paris will be inundated during the shift, to the horror of anyone clinging to their romantic city, intending to ride out the shift. The flood tide coming in from the Atlantic, as it first is stretched so that land bordering the Atlantic drops by over 100 feet in sea level and then as it sloshing back and forth during the shift itself, will be beyond the imagination of most, who tend to think in terms of storms driving waves inland and not global catastrophes with a shifting crust. The flood tide during the shift will curl quietly around buildings and along roads and streets, flooding basements and foundations until the ground under them becomes soft so that tipping sideways or sinking can occur, breaking windows as it rises to flood lower levels and prevent escape in any direction except by boat, and ultimately rising over rooftops so that frantic residents are padding for their lives. Then the flood tide recedes, back out to sea, dragging all it has captured with it. Those in France who would survive the coming shift must plan not only to be above 650-700 above the current sea level within two years, after the polar melt, but to be at more than that level during the shift. Escape to the Alps, or to the mountains of northern Spain, and be watchful for tidal bore even then.
