Antarctica’s potential collapse could damage coastal cities across the globe

NYC for example was underwater in a recent storm doing a lot of damage and largely shutting down the city

NYC was not underwater. A small part along the rivers got flooded due to poor drainage and river water water backflooding the sewer system. That is, water went into the sewers from the rivers and then got pushed up. The water then settled into low areas (basements and such), causing lots of damage.

At no time was any part of NYC "underwater".

This [0] is my kids' elementary school and the ballfields they play in, during Superstorm Sandy, and I assure you that it was very much underwater. Interestingly, the water came north up West Street, not east from the Hudson, but it's hard to see how that matters.

The expected sea level rise this century does not (most likely) put NYC underwater at high tide, but it does whenever there is a storm surge associated with high tide [1]. Sandy alone cost NYC at least $19 B [2].
