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.

Prepared as part of the High Water Line | Miami project/movement, this video depicts sea level rise in greater metropolitan Miami at one-foot intervals, ranging from one foot to ten feet.
Threatened by rising seas, some of the world’s small island developing states (SIDS) are demanding that the U.N.’s new set of Sustainable Development Goals place a high priority on the protection of oceans and marine resources.
Narrow ribs of dirt and rock beneath Antarctic glaciers help slow the glaciers’ flow into the sea, according to new research from scientists at Princeton University and the British Antarctic Survey. Understanding the factors that control the glaciers’ flow to the sea is important because their melting contributes significantly to sea level rise.
A scheme to combat flooding by surrendering land to the sea will be completed on Monday on the south coast.
A recent slowdown in global warming has led some skeptics to renew their claims that industrial carbon emissions are not causing a century-long rise in Earth’s surface temperatures. But rather than letting humans off the hook, a new study adds support to the idea that the oceans are taking up some of the excess heat, at least for the moment.
A team of scientists, led by the University of Southampton, has developed a new method to help the world’s coasts adapt to global sea-level rises over the next 100 years.
Some islands in the Pacific could be getting larger, but this doesn’t not necessarily mean sea level rise is not a threat.
No nuclear power plant in Sandy’s path was in imminent danger of a meltdown, but the force and size of the storm surge served as a warning that rising seas and higher storm surges, could eventually have a devastating effect on the seven low-lying nuclear power generating sites on the Northeast Coast in future hurricanes…
Satellite imagery over the southeastern Everglades confirms long-term trends of mangrove expansion and sawgrass habitat loss near the shore. The trend is related to salt water intrusion caused by sea-level rise and water management practices, according to a new study.
