As the sea rises, the very foundations of American history are at risk of being washed away. This is not a metaphorical threat, but a very real and present danger, as evidenced by the ongoing archaeological work at Jamestown, Virginia. This small island along the James River holds a disproportionate amount of historical significance for the United States.
Jamestown, founded in 1607, was the site of the first permanent English settlement in North America. It witnessed the convening of America's first representative assembly in 1619, the marriage of Pocahontas to John Rolfe, and the arrival of the first enslaved Africans, marking the beginning of a system of slavery that would have a profound and lasting impact on the nation. Sean Romo, director of archaeology for Jamestown Rediscovery, emphasizes the importance of this place, stating, 'For American history, it's hard to have more of an impact than Jamestown. It all starts here. Without Jamestown, there is no modern United States.'
The archaeological work at Jamestown has been remarkable, uncovering over 5 million artifacts, including glass bottles, pottery, tools, beads, and human remains. These discoveries have significantly enhanced our understanding of England's first successful colony and the diverse group of people who lived and interacted there: English settlers, the Powhatan people, and the first enslaved Africans brought to English America. However, this rich historical site is now under threat from rising waters.
Sea levels have risen approximately 1.6 feet over the last century, and this trend is accelerating. Scientists project that another three feet or more will be added by 2075. The James River is steadily eroding one side of the island, while expanding wetlands encroach from the other. Excavation pits frequently flood after heavy rain or unusually high tides, posing a significant challenge to the archaeological work.
The situation at Jamestown is a stark reminder of a broader problem affecting all along America's coastlines. The burning of fossil fuels is warming the planet and melting its ice sheets, causing seawater to expand and contribute to rising sea levels worldwide. By 2050, an estimated 2.5 million Americans, along with many of the nation's most treasured historic sites, could face severe coastal flooding, according to Climate Central.
The consequences of rising sea levels extend far beyond archaeological sites. Flooded roads and parking lots restrict visitor access to national parks, historic forts experience more frequent inundation, and barrier islands along the southeast are eroding rapidly, making some landscapes almost unrecognizable. The Outer Banks of North Carolina provide a stark example, where homes continue to collapse into the Atlantic as the shoreline retreats. Engineers had to move the Cape Hatteras Lighthouse nearly a quarter mile inland in 1999 to protect it from the encroaching sea.
However, not all landmarks can be relocated. Rob Young, a coastal geologist, points out that some places, like Fort Sumter, cannot be moved. The country will have to make difficult decisions about which places can be realistically defended and which may ultimately have to be surrendered to the changing coastline. Young emphasizes the need for a national conversation about what can be saved and what cannot.
At Jamestown, efforts to protect the site include reinforcing the sea wall with giant boulders, which may provide temporary relief but is not a permanent solution. Romo urges immediate action to protect Jamestown and ensure that future generations can continue to learn about and experience the place where American history was made. He states, 'If we do nothing, we're gonna go from Jamestown Island to Jamestown Islands in the next 50 years. The time to act is now.'
The threat of rising sea levels to American history is a stark reminder of the urgent need for climate action. As the sea rises, the very foundations of our past are at risk, and it is up to us to take the necessary steps to protect them.
