Even under the best-case scenarios for climate change, much of New York City will be under water in 100 years. The city would be smart to retreat from its waterfront, according to experts quoted in a recent alarming feature article in New York magazine.

But should the city really abandon its coastlines? And, given current political realities, how could it even do so?

The article, written by Andrew Rice, suggests that waterfront areas where new high-rise offices, apartment buildings, and parks are being developed — such as the far west side of Midtown Manhattan, Brooklyn’s Williamsburg, and Queens’ Long Island City — will be inundated and uninhabitable circa 2100.
