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.

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.
Every year millions of school children in Bangladesh miss countless school days when their schools are flooded. But now local NGO have come up with a simple solution, building schools that float.
Sand is becoming New England coastal dwellers’ most coveted and controversial commodity as they try to fortify beaches against rising seas and severe erosion caused by violent storms.
Communities and coastal habitats in the southern Chesapeake Bay region face increased flooding because, as seawater levels are rising in the bay, the land surface is also sinking. A new USGS report concludes that intensive groundwater withdrawals are a major cause of the sinking land, that contributes to flooding risks in the region.
A new NASA-led study has discovered an intriguing link between sea ice conditions and the melting rate of glacier. The discovery adds to our understanding of how ice sheets interact with the ocean, and may improve our ability to forecast and prepare for future sea level rise.
Aerial footage shows the extent of damage caused to properties and coastal landscape after the worst tidal surge in more than 60 years battered the east coast of Britain…
Geoscientists at Rutgers and Tufts universities estimate that the New Jersey shore will likely experience a sea-level rise of about 1.5 feet by 2050 and of about 3.5 feet by 2100 — 11 to 15 inches higher than the average for sea-level rise globally over the century.
Despite the fact that recent studies have focused on climate change impacts on the intensity and frequency of tropical cyclones themselves, sea level rise and shoreline retreat remain the two more certain factors expected to drive an increase in future flood risk from such storms.
A New Zealand judge on Tuesday rejected a Kiribati man’s claim that he should be granted refugee status because of climate change.
