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.

What are the obligations under international law of a State for ensuring that activities under its jurisdiction or control that emit greenhouse gases do not cause, or substantially contribute to, serious damage to another State or States? Vulnerable countries, like Palau, that have not contributed to global warming, pressed this question in front of the ICJ.
Jakobshavn Isbræ (Jakobshavn Glacier) is moving ice from the Greenland ice sheet into the ocean at a speed that appears to be the fastest ever recorded. Researchers measured the dramatic speeds of the fast-flowing glacier in 2012 and 2013.
In a report released last September, the IPCC predicts a sea level rise of 28 to 98 centimetres by 2100. Even by the most conservative estimate, this would destroy 12.5 percent of Egypt’s cultivated areas and displace about eight million people, or nearly 10 percent of the population. But it is not just rising sea levels that threaten Egypt’s northern coast, the delta itself is sinking.
The owners of a five story building built on a coastal dune in the french southwestern town of Soulac-sur-Mer, have been ordered to evacuate. Built 40 years ago, 200 meters away from the shoreline, the building now stands only 20 meters away from the ocean.
Prehistoric shell mounds found on some of Florida’s most pristine beaches are at risk of washing away as the sea level rises, wiping away thousands of years of archaeological evidence.
Grain by grain, West Africa’s coasts are eroding away, the dry land sucked under the water by a destructive mix of natural erosion and human meddling… Nyani Quarmyne has poignantly photographed the impacts of climate change on people living on the Ghana coast.
Most of America’s urban infrastructure is coastal. Of the 25 most densely populated U.S. cities, 23 are along a coast. And two of the biggest threats from climate change are increasingly intense storms and rising sea levels.
For most of Hawaii, the winter means big swells and excellent surfing. But for one neighborhood, the recent waves caught more than just surfers.
Sea levels off the California coast will rise up to 2 feet by 2050 and up to 5.5 feet by 2100, scientific research suggests. Already, sea levels have risen in San Francisco by 8 inches over the past century.
