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.

Canada’s Arctic Archipelago glaciers will melt faster than ever in the next few centuries.
Antarctica’s topography began changing from flat to fjord-filled starting about 34 million years ago. Knowing when Antarctica’s topography started shifting from a flat landscape to one with glaciers, fjords and mountains is important for modeling how the Antarctic ice sheet affects global climate and sea-level rise.
As each Arctic summer brings less sea ice, two new studies warn of major changes, from devastating storm surges to huge increases in shipping.
Scientists have known for some time that sea level rise around the globe will not be uniform, but in this study researchers show in great detail the global pattern of sea-level rise that would result from two scenarios of ice-loss from glaciers and ice sheets.
The widespread reduction in Arctic sea ice is causing significant changes to the balance of greenhouse gases in the atmosphere. This is shown in a new study conducted by researchers from Lund University in Sweden, among others.
Philippines is having to adapt and adjust to rapidly deteriorating climatic trends at a great cost to its economy
The Marshall Islands and other low-lying island nations appealed to the U.N. Security Council to recognize climate change as an international security threat that jeopardizes their very survival.
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.
