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.

For sentimental as well as environmental reasons, some homeowners will spend millions of dollars to move a coastal house to a new, better location.
In the Senegalese town of Saint Louis, rising sea levels means that every year the sea gets closer to peoples homes and it is now just a matter of when, not if, their houses are swept away.
The world’s glaciers lost 260 gigatons of water each year between 2003 and 2009, making these rivers of ice responsible for almost a third of sea-level rise in that time, new research finds.
Scientists have to be careful when looking at Earth for evidence of past sea level changes from the planet’s cycles of glacial advance and retreat.
These dramatic photos show the changing face of a popular beach that has had an astonishing 6,000 truckloads of sands washed away in just three years.
A team of researchers led by Associate Professor Edward L. Webb of the National University of Singapore (NUS) is calling for the global adoption of a method to identify areas that are vulnerable to sea-level rise.
On the surface, it looks like America is a place where scientists and scientific achievements are held in high regard. However, just below the surface, there is another America. This America is populated by people who, on economic, political or religious grounds, have chosen to reject the consensus of the global scientific community on various topics. By Alexander Glass and Orrin Pilkey.
In the aftermath of Superstorm Sandy, local governments are rethinking how to best protect the U.S. coastline from storms and flooding, which appear likely to exert a larger toll as the result of sea level rise and climate change.
With coastal areas bracing for rising sea levels, new research indicates that cutting emissions of certain pollutants can greatly slow sea level rise this century.
