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.

A new Union of Concerned Scientists study evaluated the risks of climate-induced inundation at a sample of 18 military bases on the East and Gulf of Mexico coasts. Flooding and storm surge at Langley and other coastal military installations will only get worse — maybe a lot worse.

Sea-level rise is upon us, and in the near future we will be forced to retreat from the shoreline. North Carolina has chosen the impossible path of holding the shoreline in place, locking the next generation into a future filled with catastrophic loss of property and human lives…

Climate change has barely registered as a 2016 campaign issue, but in Florida, the state which usually decides the presidential election, the waters are lapping at the doors of Donald Trump’s real estate empire.

In the face of climate change impact and inevitable sea level rise, scientists studying New York’s Hudson River estuary have forecast new tidal wetlands, comprising perhaps 33 percent more wetland area by the year 2100.

A number of Alaska Native villages have been impacted so severely by these climate-induced threats, they have decided to relocate. Yet there is no agency designated to pay for and help implement an entire community’s move.

“Rising Tides” explores the topic of coastline erosion, showing what has been done in the past, what is being done now, what worked, what didn’t and what the coastal areas can expect in the future.

For most people seeing is believing. Sea levels are rising, and the number of coastal flood days has increased dramatically. Unlike the drought, it is difficult to understand what future sea level rise will look like for our coastline.

In the U.S., North Carolina stands alone in doing basically nothing of consequence in sea level rise planning and even discourages state employees from mentioning global climate change. Instead, the response of North Carolina has been to hold the shoreline in place at great cost and even encourage further development…
