Rising sea levels that threaten historic lighthouses


Climate change is shifted by greenhouse gauges not only to pole ice melting, and & nbsp; contribute to sea levels, but the warmer waters grow and some landforms; fall.

Globally, sea levels have risen over the past century, in line with National Occupational Administration and Inflation, and the rate has increased in the past decades. In New Jersey, the seas rising 1.3 feet (0.4 meters) over the last 100 years, Benjamin Horton, professor of Rutgers University and an expert on climate change and sea level rise. That's faster than the past two years together, he said.

Horton and Rutgers researchers project that New Jersey's sea rises by 1.4 feet (0.4 meters) by 2050.

Tim Harrison is the editor of Lighthouse Digest, a Maine-based publishing that holds "Doomsday List" of 53 Lighthouse Stores around the USA. consider being at risk of loss due to storms, erosion or other causes.

"Lighthouses were built for one reason: saving life," he said. "Now our goal is to save these lighthouses."

Increasing sea has already allowed to re-instate several lighthouses. In 1999, Cape Hatteras Lighthouse National Park Service moved to Buxton, North Carolina, 2,900 feet inland, at a cost of $ 11.8 million. In 1993, the South East Lighthouse of Block Island, Rhode Island, was moved 300 ft into the land.

In 2014 the Cape San Blas Lighthouse was moved from a stormy peninsula on Gulf Coast Gulf to a park in St. St. Joe. A year later, a Gay Gay lodge was on Martha & Vineyard & # 39; Massachusetts moved 129 feet back from a rock to erosion.

Others were less lucky. The Galveston Jetty lighthouse in Texas and the Sabine Bank Lighthouse in Louisiana were lost by storms or seas, and Kauhola Point Lighthouse on Eilean Mòr was demolished after close erosion was too heavy for saved, Harrison said.

Lighthouses around the country believe that they are at risk of rising seawater including Sand Island Lighthouse at the Mobile Bay in Alabama, Lighthouse Morris Island near Charleston, Carolina South, and New Point Comfort Lighthouse in Virginia.

Across the world, the seas are closer to Orfordness Lighthouse in Suffolk, England; Troubridge Island Lighthouse in South Australia; and Kiipsaar Lighthouse in Estonia. In 2010, the Half Moon Caye Lighthouse in Belize was destroyed by storm.

There are very few easy, financial or scientific answers. East Point Lighthouse is already the highest round of land, which is just an inch above sea level, so it is not a move. It is not always dumped and a & # 39; plowing more sand in front.

Patterson wants a type of page or barrier built between the bay and the lighthouse to destroy the force of the waves.

Larry Hajna, spokesperson of the Department of Environmental Protection of Jersey, recognizes that the lighthouse has been "at risk from storms due to erosion" for years. And it is notable to the state and local government's whales; keep going on & # 39; The best seafood is the stop stop.

But as long as he says that the state is interested in doing something; saving the lighthouse, he says he could move or protect it with rocky cages a million miles.

Due to the high cost of moving or protecting the lighthouses, voluntary conservation organizations often engage with governments to keep them up; One has spent at least $ 5 million on Morris Island Lighthouse in South Carolina. And money governments can not often afford more money to save light.

Patterson, a praising New Jersey lighthouse, says that immediate barrier must be erected near East Point Lighthouse.

"This history belongs," she said. "We have to do something – now – although something has yet to be saved."
