Sea Level Rise
There will always be beaches, but sea level rise will ensure that they will not be in the same place in the future. The beaches will still exist throughout this change, but many of the buildings may not. Efforts to save development, however do threaten beaches, such as shoreline armoring structures.
Although relative amounts of rise may seem very small, only a few millimeters per year, the cumulative effect of these small rises each year over a long period of time (100+ years) causes major problems. Accelerated rates of erosion are attributed to sea level rise and erosion causes large economic losses around the world each year due to the close proximity of buildings and critical infrastructure. This includes transportation systems, gas and oil lines as well as electricity lines and power plants.
Most developed coasts and beaches have buildings very close to the ocean leaving little room for the ever-expanding ocean. The future effects of sea level rise on coastal civilization over the entire world are of great concern. Over half of the world’s population lives within 100 km of the coast. Over the next 50 years, damage due to coastal development will be devastating, but if the rate of sea level rise increases, the results could be catastrophic. This issue threatens areas from New York City in the United States to the Pearl River Delta in China to the Maldives.
The world map below allows you to see elevations of coastal areas. Areas in red are the lowest in elevation and are most prone to flooding. Check out Manhattan in New York City. If you think the situation there looks dire, be sure to check out the effects of a 2 m rise in sea level on Pearl River Delta in China, home to more than 40 million people.

In recent decades, Antarctica and Greenland have played minor roles in the world’s rising oceans. But this is changing. Rising sea levels don’t just put places underwater, but every centimetre increases the impacts that storm surges have on people, homes and coastal infrastructure.

Five years ago, the Science Panel of the North Carolina Coastal Resources Commissioner presented a report outlining that sea levels along the coast could rise as much as 39 inches over the next 100 years. The General Assembly passed a law forbidding communities from using this report to pass new rules. Now, almost three years later, the scientists have come back with a new report, but it is hardly complete and universal.

A Dare County building inspector has put up “unsafe structure” notices on six oceanfront houses north of this town on Hatteras Island, NC. Most of the recent erosion seems to be in an area where owners had placed sandbags in front of the houses.

Miami Beach’s condo boom is bubbling hot, with glass towers being built as fast as they can be—even as scientists say rising seas could swamp much of the storied city by the century’s end.

Soft sand shifting south will eventually mean cars will no longer be able to drive along the beaches in Volusia County. According to the study, ocean levels are rising every year, which means Mother Nature may eventually decide if cars should remain on the beach regardless of what the sand does. The report also states cities with limited beach driving have higher real estate values.

The data are in, and the numbers are unequivocal: the coast of North Carolina, and especially the northern part of the Outer Banks, is sinking into the sea.
