Sea Level Rise

Accelerated erosion

View Sea Level Rise Gallery

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.

Worsening Coastal Erosion, Québec

A fierce storm and high tides washed away large sections of the shoreline along the St. Lawrence River, leaving homes perilously close to the water’s edge. A State of alert remains as new high tides are expected around December 22nd and 24th.

Battling Ghana’s Eroding Coastline

For Ghana, the real story of coastal erosion is not about what lies at the water’s edge, but what occurs beneath the waves offshore. In the capital city of Accra, an estimated 70 percent of the beach is eroding at rates exceeding 3 feet per year.

Climate change still a hard sell, especially when it’s freezing out

The climatic consequences of our actions will fall mostly upon others, in other parts of the world and in that distant country, the future.

The world is getting warmer. Whether the cause is human activity or natural variability, thermometer readings all around the world have risen steadily since the beginning of the Industrial Revolution.

If an island state vanishes, is it still a nation?

No country has ever physically disappeared, and it’s a real void in the law. The Marshallese government faced with set of issues unique in the history of the system of nation-states associated with sea level rise impacts that are not adequately addressed in the international legal framework, seeks advice from the Center for Climate Change Law at New York’s Columbia University. Legal scholars worldwide have been asked to assemble at Columbia, next May to begin to piece together answers.

55 Percent of Venice Under Acqua Alta, Italy

Three main factors have worsened the high water in Venice, experts say; the rising floor of the lagoon caused by incoming silt, the subsidence of the city by the extraction of methane gas in the sea off Venice, and the worldwide increase in sea levels caused by global warming.

Many Coastal Wetlands Likely to Disappear this Century

Many coastal wetlands worldwide, including several on the U.S. Atlantic coast, may be more sensitive than previously thought to sea-level rise projections for the 21st century.

The Last house of Sinking Chesapeake Bay Island

The story was strange enough to be a child’s fable: In an isolated section of the Chesapeake Bay, there was a two-story Victorian house that seemed to emerge directly from the water. And, scurrying around it, there was a retiree, trying to keep the house from falling in.
