That Sinking Feeling: Rising Sea Level Isn’t Cities’ Only Water WorryPublication: NBC News Date: November 1, 2014 View Article
Some of the world’s expanding coastal cities face a two-pronged threat involving water: Sticking giant straws into the ground to suck up freshwater can cause the ground below to sink at the same time that sea levels are rising.
That interplay between subsiding land and rising seas highlights an underappreciated risk in global climate change, according to scientists.
It’s not known how many people live on coastal lands that are sinking due to excessive groundwater pumping, but about 150 million live within 3.3 feet of today’s high-tide mark. And the worst-case scenario for sea level rise by the end of this century is nearly six feet, according to a recent study.
