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.

From schools at sea to a city that perpetually sails the oceans, is climate change creating a bold new era of floating urban design..?
The last remaining stable portion of the Greenland ice sheet is stable no more, an international team of scientists has discovered. The finding will likely boost estimates of expected global sea level rise in the future.
Last month, coastlines saw extreme high and low tides known as king tides, which are caused by a chance alignment of the moon, Earth, and the sun. Now the tides are back…
Some of the world’s most recognizable and important landmarks could be lost to rising sea-levels if current global warming trends are maintained over the next two millennia.
Each coastal disaster is followed by the inevitable debates about whether rebuilding is the right decision.
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.
