Boston faces a daunting future of rising seas
Boston got a wake-up call earlier this year when the first of a string of nor’easter storms hit just as the tide was peaking. The ocean spilled into the subway and into homes up and down the coast.

Boston Harbor is subject to tides that rise as much as 12 feet, and most of its original tidal flats, which helped disperse and soften the effects of those tides, were filled in by the late 1800s. In the US, most tidal ranges are about 3 to 5 feet, so Boston is a bit unusual.
