"The project is using wind and water to sculpt the sand into gently rising dunes. It has taken nearly four years to restore a modest 3,250-foot stretch of beach and buffer the burial grounds that lie just beyond.
What the Shinnecock are doing on their land represents what climate adaptation experts call nature-based solutions. Several such efforts are underway elsewhere. New York City’s oyster reefs are being restored to protect Manhattan from storm surges. Marsh grasses have been planted to control erosion in parts of the Florida panhandle. Mangroves have been restored in Vietnam to protect coastal communities from sea level rise and storm surges.
To what extent these natural defenses will succeed in slowing down climate hazards remains uncertain. Ultimately, it depends not on nature, but on how quickly the world as a whole reduces the emission of planet-warming gases and stems the rate of sea level rise.
The global outlook for beaches is bleak. One study, published in Nature Climate Change this week, found that more than half of the world’s sandy beaches could disappear by the end of this century."
