Rising sea levels threatening historical lighthouses



The climate change accelerated by man-made greenhouse gases not only melts polar ice, but also adds sea levels, but warmer waters are expanding and some soil formations are sinking.

According to the National Oceanic and Atmospheric Administration, sea levels are rising globally in recent centuries and this ratio has increased in recent years. Benjamin Horton, a professor at Rutgers University and an expert on climate change and sea level rise, said that in New Jersey, over the last 100 years it has grown to 1.3 feet (0.4 meters). He said, dedi It's been a speed over 2000 years.

Horton and other Rutgers researchers estimate that by 2050 the seas of New Jersey will rise 1.4 meters further.


Tim Harrison is the editor of Lighthouse Digest, a Maine-based publication that protects the u Doomsday List etraf of 53 lanterns around the United States, which are thought to be in danger of being lost to storms, erosion, or other reasons.

"The lighthouses were built for a purpose: to save lives," he said. ”Now it's our turn to save these flashlights.“

Rising seas have already forced several lighthouses to move. In 1999, the National Park Service carried the Cape Hatteras Lighthouse in Buxton, North Carolina in North Carolina at a cost of $ 1198 million. In 1993, the Southeast Lighthouse at Block Island, Rhode Island, moved 300 feet inside.

Cape San Blas Lighthouse in Florida, Florida Moved to a park in Joe. A year later, the Gay Head Lighthouse in Martha's Vineyard in Massachusetts moved 129 feet back from an eroded cliff.

Others were not very lucky. The Sabine Bank Lighthouse in Harrison, Galveston Jetty Lighthouse and Louisiana, disappearing into the storm or rising seas, and the Kauhola Point Lighthouse on Hawaii's Big Island is too heavy to save nearby erosion. he said that he was destroyed.

Lighthouses around the country thought to be in danger from the rising seas include Sand Island Lighthouse in Mobile Bay, Alabama, Morris Island Lighthouse near Charleston, South Carolina, and the New Point Comfort Lighthouse in Virginia.

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

There are several easy answers, either financially or scientifically. The East Point Lighthouse has the highest depletion of land only a few inches above sea level, so moving is not an option. It also doesn't continuously collect garbage and more sand in front of it.

Patterson wants some kind of curtain or barrier between the gulf and the lighthouse to reproduce the power of the waves.

Larry Hajna, spokesperson for the New Jersey Environmental Protection Agency, admits that the lighthouse has been "very sensitive to storms due to erosion" for years. And he realizes that sand bags, which allow the state and local authorities to stand on the shoreline, are at best a stop-gap measurement.

But he confirmed the state's interest in saving the lighthouse, adding that moving or guarding stone-filled cages could cost several million dollars.

Because of the high cost of moving or maintaining lanterns, voluntary protection groups often cooperate with governments to protect governments; One of them spent at least $ 5 million in the Morris Island Lighthouse in South Carolina. And cash-strapped governments often don't save money to save flashlights.

New Jersey lighthouse advocate Patterson says a barrier should be built in the immediate vicinity of the East Point Lighthouse.

”This date is important,“ he said. "We have to do something – now – there's still something to hide."
