Those are things that are already happening ... do you know why the King Tide of early January 2018 was the highest for the next 40 years? ... perihelion is on January 5th, 2020, which is unfortunately first quarter Moon phase ... the two tidal forces are at right angles this year ... 2018 they lined up at perihelion and very close to perigee ...
Waves can get built up with the right fetch ... more common on the Pacific Coast with the more direct line on the Westerlies ... Atlantic not so much, but it can happen ... in fact ... has already happened ...
Storm surge is a matter of probabilities ... that's why there's FEMA maps ... so folks know the probabilities of getting wash away in any given hurricane season ...
People who can afford to build beachfront homes can also afford to hire engineers to figure out all these risks ... and they take into account all these water levels will be two feet higher by year 2100 ... next time you have a King Tide and a storm rolling in from the right direction, take a stick to the beach and shove it into the sand where the highest wave breaks and begins to recede ... break the stick two feet above the sand and level over ... that's where the wave will break and recede in 80 years ... how much closer to the line of homes is it? ...
