Question

Why is New York supposed to flood over in twenty years?

Answer 1

not all of new york, probably long island in about 50 years because of global warming. the sea level rises, long island is like literally sea level, not more than a few feet above.. so about 50 years unless we stop global warming. good bye to my house.

Answer 2

Because global warming is  melting the ice caps which raise up the sea levels and the misplaced water has to go somewhere, doesn't it!?

Answer 3

The ice caps and glaciers are melting at a rate unprecedented in human history.  This is causing sea levels to rise.  All low lying coastal cities will be flooded if this continues.  People have laughed at Global warming for years, but the prospect of having our major cities flooded at least gets their attention.

Answer 4

So many people. So much sewerage. It's gotta go somewhere, even at high tide.
