In the community of Rodanthe on the Outer Banks of North Carolina, residents witnessed on Friday an event that was not new and is unfortunately becoming more frequent: A house on the picturesque shoreline collapsed into the ocean.
Weather experts said that crashing waves produced by Hurricane Ernesto hundreds of miles away, combined with especially high tides, appeared to be the cause, though local officials also said that the house was at risk of collapsing before the storm. For those on the Outer Banks, the destruction was one more stark reminder of the larger force at play — climate change, which is making storms more intense and sea levels higher, accelerating the erosion of beach fronts.
Rodanthe, home to about 200 people, has lost seven homes to the ocean in the past four years. The house that was destroyed on Friday was unoccupied at the time of the collapse. There have been no reports of injuries from any of the seven collapses, according to the National Park Service.
Officials warned that many more homes are at risk for damage or collapse in the coming days as Hurricane Ernesto pummels the East Coast from afar, even as it follows a path that is not expected to hit the mainland United States. Some other homes near Rodanthe have already appeared to sustain damage.

Forecasters predict that the storm could bring dangerous rip currents and a high surf along the East Coast through the weekend. The risks could persist in the Outer Banks through early next week, they said.
In North Carolina, climate change has caused the sea level to rise by about half a foot since 2000, and the level could rise by about another foot by 2050, said William Sweet, an oceanographer with the National Oceanic and Atmospheric Administration.
