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 Reuters analysis finds that flooding is increasing along much of the nation’s coastline, forcing many communities into costly, controversial struggles with a relentless foe.
Geologists suggest that an intermediate amount of vegetation is most effective at stabilizing freshwater river deltas. Vegetation on marsh surfaces in river deltas can slow the flow of water and cause more sediment to be deposited, helping prevent sea-level rise from drowning sensitive marshlands.
Walking along the waterfront in Fort Lauderdale and admiring the 60-foot yachts docked alongside impressive homes, it’s hard to imagine that this city could suffer the same financial fate as Detroit.
Observations show that the heat absent from the Earth’s surface for more than a decade is plunging deep in the north and south Atlantic Ocean, and is part of a naturally occurring cycle.
Satellite data shows ice sheets of Greenland and Antarctica are declining at record speed. The annual loss of ice has doubled in the case of Greenland and tripled in the West Antarctic compared to figures from 2009.
The world’s 52 small island developing states (SIDS), some in danger of being wiped off the face of the earth because of sea-level rise triggered by climate change, will be the focus of an international conference in the South Pacific island nation of Samoa next month.
Rapid warming of the Atlantic Ocean, likely caused by global warming, has turbocharged Pacific Equatorial trade winds. This has caused eastern tropical Pacific cooling, amplified the Californian drought, accelerated sea level rise three times faster than the global average in the Western Pacific…
From above, Arctic ice looks quite different in summer than it does in winter. As temperatures rise in the summer, turquoise splotches of color begin to speckle the ice surfaces. The splashes of blue are melt ponds, areas where snow has melted and pooled in low spots on glaciers and sea ice.
A NC state-appointed science panel began work last week on an update to a controversial sea-level rise report, members of the panel said Thursday at a meeting of the Coastal Resources Commission.
