1. Mexico City, Mexico
Mexico City sits atop a fickle lake bed in the Valley of Mexico and has been facing the risk of getting submerged. Parts of the city are sinking at the rate of eight inches every year. According to AZCentral.com, Mexico City’s drainage capacity has decreased by 30 percent since 1975.
- There are several projects underway to keep this sinking city afloat, including a 23-foot-wide ($1.1 billion) Eastern Drainage Tunnel that will deposit waste water about 40 miles north of the city.
- The tunnel should be completed by 2012. Work is also being done to help save the architectural gems — like the popular Metropolitan Cathedral.
2. Venice, Italy
The Venetians chose to construct canals instead of roads and built buildings atop submerged wooden planks hundreds of years ago. This dig for fresh water has taken its toll on the city which has sunk no less than a foot in the last hundred years. Acqua alta (high water) has plagued this ornate tourist hotspot for centuries.
- Water levels in the Mediterranean Sea are also rising.
- Preserving Venice has been a priority of the Italian Government for about 30 years.
4. New Orleans, Louisiana
It may come as a surprise that half of New Orleans is at or even below sea level. This makes the city even more prone to tropical storms. In 2006, National Geographic noted that while the city sank at about a quarter of an inch per year, (after Hurricane Katrina struck) and the levees designed to safeguard the city sunk at an astonishing at four or five times the rate.
- Experts say that not much can be done to save the Big Easy.
- “an alternative would be to elevate the first floor of buildings to at least the 100-year flood level.”
5. Shanghai, China
Shanghai was originally a small fishing village and this coastal city was built on swamplands surrounding the mouth of the Yangze River. The city is known for its awe inspiring skyscrapers and also for some of the best shopping venues in the continent. PBS, Shanghai sank roughly eight feet between 1921 and 1965, which equals two inches per year. The city still continues to drop at a rate of about half an inch per year.
- The Chinese government has put many regulations in place to curb this menace.
- Every new building has to strictly conform to the government’s measures.
7. Houston, Texas
Arguably Texas’ most cosmopolitan is struggling to stay above ground. It’s a major energy hub and the taking-off point for U.S. space exploration. America’s fourth-largest city was built on a foundation of sand (And quite literally so). Houston has depended on underground water for it’s needs and that kind of extraction has taken its toll on the city’s foothold. Most parts of the city are sinking consistently at the rate of two inches every year.
- There are areas where they’ve stopped extracting ground water and those areas have experienced a decline in the sinking.
- If Houston is on your list of cities to see, you best prepare soon for take-off.
8. New York City, New York
America’s most densely populated city under great threat from global warming. New York is situated at the mouth of the Hudson river where it flows into the Atlantic ocean. There’s going to be fierce sea levels and bigger and deadlier tropical storms. Science Daily reports that the sea levels in the New York City area are expected to rise about twice as quickly as sea levels around the world.
- Flooding is only going to be a single issue that’d affect the Big Apple.
- Not only will the Empire City be transformed into a wading pool, but it will slowly be washed out to sea.
10. Bangkok, Thailand
The capital of Thailand is going under water at a tremendous pace. And a shoddy foundation isn’t to blame this time. Bangkok is resting on the Chao Phraya River which 30 miles south of the city centre into the Bay of Bangkok. This big city is actually probably under risk of going water completely. It may not take even around seven years for such a mishap to occur.
- According to Thai scientist Dr. Ajong Chumsai na Ayudhya, the fate of Bangkok can best be explained by global warming.
- Scientists have warned against bigger and more severe Tsunamis.
The Atlantic may swallow most of Miami along with its famous beach culture well within the next century. Levees and sea walls have been effective in New York but they won’t work in Miami. A porous limestone bedrock exists beneath Miami which could allow rising ocean levels to seep beneath the city. The aquifiers are already in trouble over contamination with salt water.
- The National Oceanic and Atmospheric Administration created a sea rise simulation that allows users to map how much of Miami may be submerged.
- The American government will have to take Miami seriously!
13. The Netherlands
It isn’t just small islands that are threatened by rising water levels; entire countries like The Netherlands are under a great threat too! The story of the little Dutch Boy illustrates how the country is heavily dependent upon technology like flood gates etc. to keep the sea out. It’s going to be very difficult indeed for Rotterdam and other Dutch cities to keep their heads above water because of rising sea levels and intense storms warns the same research that warned of floods in Shanghai.
- A catastrophic nine-meter(30-foot) increase would obliterate most of the Netherlands.
- An interactive map on Geology.com shows that a one-meter (3-feet) increase in could demolish much of Brugge, the Hague, and Amsterdam.
It is under great threat by the rising oceans. According to the United Nations Environmental Programme a five-foot (1.5 meter) increase in sea level could submerge 22,000 square kilometers of the country. This flooding is sure to affect no less than eighteen million people. Much of the Sunderbans is going under water if and when any of Bangladesh’s coastline does.
- Sunderbans is a mangrove ecosystem and is the natural habitat for Bengal tigers, mugger crocodiles and their prey, including chital deer and rhesus macaques.
- The forest is a major tourist attraction and helps attract Forex for the dwindling economy of Bangladesh.
It has been at a terrible risk of disappearing for quite some time now. The highest point in the Maldives is no higher than a meager seven feet ten inches above sea level or 2.4 meters. It’s an average of five feet approximately. Tourism makes for a major portion of the Maldivian economy. The maldives have been going under water and it is a known fact that sooner rather than later the island will submerge.
- The income from tourism will then come to the aid of the citizens and they’d be able to relocate well.
- The Guardian reported that the Maldivian government began diverting a portion of tourism revenues to purchase land for its 300,000 residents.
