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.

The Thai capital, built on swampland, is slowly sinking and the floods currently besieging Bangkok could be merely a foretaste of a grim future as sea level are forecasted to rise by 19 to 29 centimeters by 2050 as a result of global warming, experts say.
Scientists investigated how California’s interconnected San Francisco Bay and Sacramento-San Joaquin Delta (the Bay-Delta system) is expected to change from 2010 to 2099 in response to both fast and moderate climate warming scenarios. Results indicate that this area will feel impacts of global climate change in the next century with shifts in its biological communities, rising sea level, and modified water supplies.
Although climatic factors and sea level rise are influencing hypoxia, efforts to reduce the flow of fertilizers, animal waste and other pollutants into the Chesapeake Bay, appear to be giving a boost to the bay’s health, a new study that analyzed 60 years of water quality data has concluded.
While satellites have tracked the formation of new icebergs, this is the first detailed airborne survey of such an event.
Island states facing rising seas driven by global warming slammed on Thursday suggestions by some rich nations that a comprehensive climate deal can wait until 2018 or later. Such proposals are “both environmentally reckless and politically irresponsible…”
The global output of heat-trapping carbon dioxide jumped by the biggest amount on record, the U.S. Department of Energy calculated, a sign of how feeble the world’s efforts are at slowing man-made global warming.
Tangier Island lies in the middle of the Chesapeake Bay and is 92 miles (148km) southeast of Washington, DC. This small piece of land is barely above sea level and its 500 residents are fighting for its survival.
Residents fled Thailand’s capital, Bangkok, on Thursday after authorities warned the city would soon be flooded and called a special five-day holiday to let people escape.
Pacific islands and other low-lying countries experiencing global warming consequences and rising seas, will use a Commonwealth summit this week to ramp up pressure in the climate change debate, on powerful and majors polluters – the United States and China – that are not doing enough to cut their greenhouse gas emissions.
