Ice does float but the ice these dire predictions are talking about is the 99% of frozen fresh water in two places, Greenland and Antartica. This is all on land masses and if it melted the seas would rise.
It would almost all have to melt for the oceans to rise that much, which is very unlikely.
Anyway the Dutch have handled it and given time we could too.
It’s more likely that space aliens will destroy New York, than rising oceans!
Bloomberg should just create a new city tax to pay for all the dams and dykes he needs to control HIS environment.
It’s not my problem ;-)
