  • 10 World Cities That Will Completely Disappear by 2100

  • 10. San Francisco, USA

  • Most people realize the earthquake danger in San Francisco, yet the enormity of the

  • potential devastation is almost beyond comprehension. According to the University of California,

  • research forecasts a 75% probability that an earthquake of a 7 or greater magnitude

  • will occur by 2086. Will the survivors elect to re-build the majestic city? Will they be

  • able to? Prior to Katrina, the population of New Orleans was close to 500,000. Afterwards,

  • the population shrunk by about half. It’s rising again, but the demographics are still

  • far lower than they were pre-Katrina. The population of San Francisco is about 900,000.

  • Tall structures abound and there’s no such thing as a completely earthquake proof structure.

  • In fact, the population of San Francisco is shrinking. Not only is the city pricey, but

  • many are wondering where they or their relatives may end up with the city’s hazardous coastline

  • and predicted disasters!

  • 9. Venice, Italy

  • One of the world’s most romantic cities has been sinking for about a millennium. The

  • pace has increased rapidly over the last 100 years, with the soil level sinking about 24

  • centimeters. Venice’s vulnerability to sea and groundwater level change is extremely

  • serious. For example, 100 years ago St. Mark’s Square flooded around nine time per year,

  • and now it’s inundated with water 100 times per year. The government has been working

  • on plans to protect Venice, but will they work? No one knows.

  • Preserving Venice has been a priority of the Italian Government for about 30 years. Several

  • billion euros have been dedicated to a major flood defense system, called the MOSE Project.

  • Proposed since the 1970s, it’s basically a series of floodgates to stretch across three

  • openings that connect the Venetian Lagoon with the Adriatic Sea. However, the progress

  • of the project has been checkered with stops and starts, new completion dates and now possible

  • illegality. In June the Mayor and other top officials were arrested on corruption charges

  • involving MOSE. It’s been suggested that the City be moved to higher land altogether

  • to protect its population and precious art and frescoes.

  • 8. Detroit, USA

  • Motor Citymay becomeAbandoned Cityas the population of Detroit continues to

  • decline. If these trends keep up, Detroit will be changed beyond recognition by 2100.

  • The culprits include major economic and demographic decline, including moves to the suburbs. At

  • its peak in 1950 the population was 1,850,000, compared with its present 701,000. Global

  • competition in the automobile industry, significant unemployment, crime rates and severe urban

  • decay have rocked the city. In 2013, Detroit filed the largest municipal bankruptcy case

  • in American history. The unemployment rate is 23.1%, and one-third are living below the

  • poverty level. Parts of the city are already ghost towns as urban decay has set into once

  • thriving communities. Some areas look completely wild. Detroit also has some of the highest

  • crime rates in the United Statesin 2012 their murder rate was 53 per 100,000, ten

  • times that of New York City. A 2012 Forbes report named Detroit the most dangerous city

  • in the United States for the fourth year in a row.

  • In 2010, Mayor Bing put forth a plan to bulldoze one fourth of the city and concentrate the

  • population into certain areas to improve the delivery of essential city services. In February

  • 2013 the Detroit Free Press reported the Mayor’s plan to accelerate the program and desire

  • for federal funding to tackle Detroit’s problems in order toright size the city’s

  • resources to reflect its smaller population.”

  • 7. Ivanovo, Russia

  • This district capital and administrative center of Ivanovo Oblast is in serious decline. Once

  • a major textile center, the city attracted women seeking work. This created a significant

  • gender imbalance that gave it the nicknameThe City of Brides.”

  • Since the breakup of the Soviet Union, 60% of the population had to live on food they

  • grew, a survival strategy known as thedachma movement.” Growing textile competition from

  • China and other emerging economies also eroded the economy. The combination of a low birthrate,

  • high poverty, crime, drug and alcohol abuse, high mortality rates, poor quality of dwellings,

  • andgreybusinesses have all but destroyed the once thriving city as its youth are leaving

  • to seek an education and re-settle somewhere with modern industry.

  • 6. Mexico City, Mexico

  • Mexico City began as the home of an ancient empire and grew into one of the world’s

  • largest cities, with more than 20 million people living in this modern metropolis. It’s

  • built on top of the Aztec capital, Tenochtitlan. It was here where, in 1519, Cortes allegedly

  • met Montezuma, the Aztec emperor. After conquering the Aztecs, Cortes, in Spanish tradition,

  • placed the square at the heart of the city, surrounding it by buildings representing the

  • church and the government. Yet the city, home to Diego Rivera murals, cathedrals and palaces,

  • is literally sinking. The problem is its base. A dried lake bed makes a poor foundation.

  • According to government officials, Mexico City is sinking at a rate of four inches a

  • year and has sunk 10 meters in the past sixty years. So be prepared to walk carefully when

  • you visit.

  • 5. Banjul, Gambia

  • The small West African nation of Gambia may lose its capital due to a combination of the

  • rising ocean and erosion. Banjul is at risk of going underwater as sea levels rise by

  • one meter as a result of climate change. Settlements will be eroded, and over half of the country’s

  • mangrove forests and a fifth of its rice fields will be lost. The decrease in rice production

  • would be disastrous, as would other environmental changes including droughts, floods and storms.

  • As tourist attractions and fisheries are located in the coastal zones, the economy would be

  • critically affected. The government is trying to improve coastal defenses, but whether they

  • can save the city and the coast is unknown.

  • 4. Timbuktu, Mali

  • When sand dunes advance on fertile land, desertification is a problem. The city in southern Africa

  • facing the greatest danger was a center of Islamic education during the 15th and 16th

  • centuries. Timbuktu is over over 1,000 years old and is known for its tourist attractions,

  • which include beautiful beaches with turquoise reefs and many historical sights. Sadly, your

  • grandchildren may have to find other exotic locations to go snorkeling, as some parts

  • are already half buried in sand despite several projects to re-green the area.

  • 3. Naples, Italy

  • Naples is the magnificent capital of the Italian region Campania and the third-largest municipality

  • in the country. As of 2012, the population was around 960,000 with an urban area of about

  • 3.5 million, making it one of the largest metropolises on the Mediterranean Sea. One

  • of the oldest continuously inhabited cities in the world, Napleshistoric city center

  • is the largest in Europe and is listed by UNESCO as a World Heritage Site.

  • Naples has long been a major cultural center with a global sphere of influence, particularly

  • during the Renaissance and Enlightenment eras. Visitors are treated to historically significant

  • sites, including the Palace of Caserta and the Roman ruins of Pompeii and Herculaneum.

  • Its nemesis has been the time-bomb, Mount Vesuvius, located in the Bay of Naples. The

  • volcano that destroyed Pompeii in 79 BC erupts about every 100 years, with the last eruption

  • coming in 1944. It’s expected to do its damage once again in the mid-2000s, putting

  • the city and half a million people in thered zoneif theyre not evacuated

  • in time.

  • 2. Bangkok, Thailand

  • Bangkok is in trouble. The city is sinking, while sea levels are rising. Building foundations

  • are being pushed into the muddy soil and underground aquifers are being drained for drinking water.

  • Rising sea levels are the real problem, though, with estimates giving the city no more than

  • a century until the streets become canals. While scientists agree that the problem needs

  • to be addressed they disagree on the best solution, while the government doesn’t appear

  • to be looking for any solution at all. The city won’t flood overnight, but if you want

  • to check out its awesome robot building it may be better to go sooner rather than later.

  • 1. Other American Cities in Jeopardy

  • Rising seas and global warming have put U.S. coastal cities at risk. Residents should consider

  • either seeking higher ground or avoiding any long-term investments. Since 1889, global

  • sea levels have raised about eight inches, and theyre still climbing. Rising seas

  • dramatically increase the odds of damaging floods from storm surges. One analysis found

  • the odds of floods occurring by 2030 are on track to double or worse.

  • Nearly five million Americans live less than four feet above high tide. In decades, New

  • York City, New Orleans, Boston, Washington D.C., and southeast Florida may be overcome

  • by flood conditions made worse by climate changes. Other cities that could be affected

  • include Baltimore, Charleston, Houston, Galveston, Los Angeles, Long Island, Sacramento, Philadelphia,

  • Delaware, Portland, Providence, San Diego, Savannah, Seattle, Tacoma, Virginia Beach

  • and Norfolk. That pretty much just leaves Kansas, but then you run into the tornado

  • problem. And you’d have to live

  • in Kansas.
