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.

Experts on the sea level rise triggered by climate change have long known that it will proceed faster in some places than others.
During World War II, a German U-boat made its way into New York Harbour. It fired two torpedoes at a British tanker, splitting the hull in three places and igniting it in flames. The captain and 35 members of his crew burned to death. Seventy years later, New York Harbour is Lower Manhattan’s first line of defence against another threat: the rising tides of the sea.
According to a new technical report, the effects of climate change will continue to threaten the health and vitality of U.S. coastal communities’ social, economic and natural systems.
Researchers explored ancient rock formations on South Africa’s coast. They are looking for critical clues from records of past climate change to help predict sea level rise in a warming world.
Professor Andrew Cooper, Professor of Coastal Studies in the School of Environmental Sciences at the university’s Coleraine campus, said a rise in sea level of even a few feet could threaten some of the world’s most iconic resorts.
In recent decades, Pine Island Glacier’s rapid retreat raised fears that the glacier could “collapse,” freeing the ice sheet it buffers to flow even more rapidly into the southern seas. The West Antarctic Ice contributes 0.15 to 0.30 millimeters per year to sea level rise.
As economic activity and populations continue to expand in coastal urban areas, particularly in Asia, hundreds of trillions of dollars of infrastructure, industrial and office buildings, and homes are increasingly at risk from intensifying storms and rising sea levels.
Future sea level rise due to the melting of the Greenland and Antarctic ice sheets could be substantially larger than estimated in Climate Change 2007, the Fourth Assessment Report of the IPCC, according to new research from the University of Bristol.
During some parts of the year, a layer of salt can be seen on the ground in eastern Cuba, which makes it difficult, and sometimes impossible, to farm. Since agronomist Orlando Coto saw this with his own eyes, he has been searching for salt-tolerant fruit trees.
