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.

Melting of a Small Ice Volume On East Antarctica’s Shore Could Trigger Persistent Ice Discharge Into Ocean
The melting of a rather small ice volume on East Antarctica’s shore could trigger a persistent ice discharge into the ocean, resulting in unstoppable sea-level rise for thousands of years to come.
In early November 2013, one of the largest iceberg in existence, named B31, separated from the front of Antarctica’s Pine Island Glacier, and is heading into the open ocean.
While the nation looks for solutions to the problem of rising sea levels, some coastal communities in Florida are taking action to save themselves from sinking into the ocean…
Faced with the prospect of losing miles of beautiful white beaches, and the millions in tourist dollars that come with them, from erosion driven by climate change, Barbados is taking steps to protect its coastline as a matter of economic survival.
The National Trust has suggested that the best strategy in some cases is simply to allow nature to run its course…
A clear national strategy is “urgently needed” to help future-proof coastal areas from rising sea levels and extreme weather, according to a report published by the National Trust, UK’s biggest coastal owners.
Arctic sea ice reached its annual maximum on March 21, 2014. And while the year was not extraordinary—the fifth lowest extent in 36 years of satellite records—the trend continues to be.
The sea has protected Venice since the fifth century, when people moved to the fish-shaped islands of Rialto for safety from mainland invaders. Over the next thirteen centuries, the seafaring city-state grew in power and strength. But the tide has turned, and the sea that once protected Venice now threatens it.
