Nearly 3 million US homes in places like Charleston, South Carolina; Miami; and New York are at risk of being flooded permanently because of sea-level rise at some point in roughly the next century, according to a recent Richmond Federal Reserve research note.
On Sept. 20, 2024, a four-bedroom, three-bathroom beach house in Buxton, North Carolina, in the heart of the Outer Banks, sold for $580,000. On Oct. 28 this year, the house, known as Mermaid’s Rest, collapsed into the ocean. It was one of five homes swallowed that day by high waves churned up by an offshore storm.
Few things demonstrate how climate change is already upending lives and fortunes quite like watching somebody’s stately vacation home topple into the drink. But Outer Banks houses like Mermaid’s Rest (a striking example first dug up by the New York Times but just one of many such cases), are mere showroom models for the havoc that rising seas are already threatening.
First, let’s get one caveat out of the way: Barrier islands like the Outer Banks are always changing shape, regardless of the climate. Homes built on the shores of such islands have always been at risk of eventually sliding off the edge like a quarter in one of those coin-pusher arcade games.
