Guardian - New York City is sinking in part due to the extraordinary weight of its vertiginous buildings, worsening the flooding threat posed to the metropolis from the rising seas, new research has found. The Big Apple may be the city that never sleeps but it is a city that certainly sinks, subsiding by approximately 1-2mm each year on average, with some areas of New York City plunging at double this rate, according to researchers. This sinking is exacerbating the impact of sea level rise which is accelerating at around twice the global average as the world’s glaciers melt away and seawater expands due to global heating. The water that flanks New York City has risen by about 9in, or 22cm, since 1950 and major flooding events from storms could be up to four times more frequent than now by the end of the century due to the combination of sea level rise and hurricanes strengthened by climate change.
