How would a comet strike sink cities world wide? Raising sea levels due to loss of ice on land explains the evidence of world wide sunken cities.
Thanks.
A comet striking the north america ice sheet at the end of the last ice age, around 10,200 - 9,500 bc. If the comet struck the ice sheet, there would be very minimal to no evidence left of the impact. I wonder where all of that water would have done? That along with the warm up of the earth's atmosphere would have caused massive melting even for the ice that wasn't directly impacted.

It was due to an Ice Dam breaking and all the water rushing out from behind it.

Comet strikes the arctic. Ice melts. Sea level rises. Cities drown. Pretty straightforward.

One comet did all this? How much energy does that require to melt that much ice covering half a continent?
I don't even want to think of doing that equation. Maybe someone in a high school physics class wants to make this a project?

They will find all the plastic waste we made.
Ohh and Fukushima... Chernobyl etc

No. Not the grand canyon.
The Carolina Bays are ellipses although some lack bilateral symmetry along either the major or minor axis. The southeast portion of many bays is more pointed than the northwest end and the northeast side bulges slightly more than the southwest side. Known major axis dimensions vary from approximately 60 meters to 11 kilometers. The Carolina Bays display a northwest-southeast orientation. Deviations from this orientation appear to be systematic by latitude (Prouty, 1952).
1. Introduction
The Carolina Bays are shallow elliptical depressions with raised rims
that occur on the Atlantic Coastal Plain along the east coast of the United
States. The geometrical elliptical shape of the bays and their particular
orientation first became apparent from aerial photographic surveys. Because
the bays have very regular shapes that are very different from
other geological structures, Melton and Schriever (1933) suggested
that they had been created by a swarm of oblique meteorite impacts.
However, meteorite fragments are not common in the region where
the bays are located, and the alignment of the bays varies by latitude instead
of being parallel as would have been expected for impacts by extraterrestrial
objects. The lack of impact evidence led to hypotheses of
geological mechanisms that could have produced the bays, such as the
modification of karst-like depressions by the action of water and wind
(Johnson, 1942). In 1975, Eyton and Parkhurst proposed that the
Carolina Bays could have formed by air blasts from explosions of fragments
of a disintegrating comet. Dating studies of the bays have concluded
that the bays were formed over an extended period of time
during the Late Pleistocene starting approximately 140,000 years ago
(Brooks et al., 2010), thus precluding the possibility that all the bays
formed at the same time.
