RICHMOND, Va. -- Islanders in the middle of the Chesapeake Bay could be among the first "climate change refugees" in the continental United States as rising seas claim their historic fishing village, a report released Thursday concludes.
The research published in the journal Scientific Reports says residents of steadily shrinking Tangier Island will have to abandon their fishing community in approximately 50 years.
As the UN climate talks continue an ocean away in Paris, "Tangier is kind of ground zero," said oceanographer David M. Schulte, lead author of the research.
The peer-reviewed research was funded by the U.S. Army Corps of Engineers, which has said millions in new infrastructure such as breakwaters could shield Tangier Island and extend its life.
Tangier's threatened existence is not news to islanders, who have seen their island and others nearby retreat through the decades. Uppards Island was abandoned nearly a century ago, but the skeletal remains of those who once lived there are occasionally coughed up during storms, such as Hurricane Sandy.
Low-lying Tangier is particularly susceptible to climate change and rising seas and the sinking of the bay -- called subsidence. The sinking is a remnant of the last ice age and glaciers north of the bay. As the ice melted, the land rebounded, while the bay began to sink.
Approximately 700 people live on Tangier, nearly half its peak population. Island watermen are prodigious fishermen, hauling in a disproportionate amount of the bay's signature crabs and oysters.
Islanders get around on golf carts and homes are clustered atop ridges to keep them beyond the reach of rising waters. Graves have had to be interred and remains moved to avoid being swamped.
Because of its isolation, many residents have retained over centuries the linguistic traces of the island's settlers, primarily from Cornwall along England's southwest coast. Jamestown settler Capt. John Smith is believed to be the first white man to set foot on the island more than 400 years ago.
By the researchers' calculations, only one-third of the island's land mass remains from what was there in 1850.
At the current rate, one island near Tangier, called Goose, will be flooded by 2038. As for Tangier, it will be splintered into three low-lying uninhabitable marshes.
The report states the construction of breakwaters and other measures, at a cost of $30 million to $40 million, could extend Tangier's lifespan by perhaps another 50 years. The report adds that "climate change is upon us and that adaption to climate change is 'not optional.' "
