Sea level rise enough by just 1 meter to disappear from the face of the earth the legendary Venice. The city, with its intricate network of canals is in danger as a result of increasing water level and its impact on local soil. In 2008 the city was struck by catastrophic floods which have caused severe damage. This cataclysm was repeated in January this year, as heavy rains coincided with high tides. The cost of restoring the buildings already damaged by these floods is estimated at tens of millions of dollars.
Global sea level to rise just enough for 2 meters to sink Amsterdam. The Netherlands is located in the lowland, and a quarter of the country is actually below sea level! Large dams to protect the land from flooding and allow you to master the Dutch territory that has long been to be swallowed by the sea. The problem is that when the sea levels rise, these dams are heavily loaded, and with the tides and storms are at risk of destruction. According to preliminary estimates, Amsterdam has around 150 years before he would become the New Atlantis.
In the case of the Hamburg water should rise by 2 to 5 meters. The city, which is the second largest in Germany, located in the floodplain of the River Elbe, a little more than 100 kilometers from the North Sea coast. The city is regularly exposed to flooding due to heavy rains, and from sea level rise, this process will only intensify. Hamburg has a modern defense system against floods, but as in the case of the Netherlands, it may not be effective when the water level rises.
St. Petersburg is also threatened by rising water at 2.5 meters. Located at the mouth of the mighty Neva River, the city is built on islands connected by numerous bridges. The city's population is accustomed to regular flooding and sea level rise, but in recent years they have become more frequent and dangerous. Barriers to protect the city from the Gulf of Finland, works as Flood Alert System. These defense systems cost a huge amount, but without them, the city will almost certainly captured water. St. Petersburg, protective systems that were completed in 2010, now serves as a model for several other low-lying cities.
For Los Angeles becomes critical water rise by three meters. Los Angeles, California as well as all - rather the area that we often associate with drought rather than flood. But this coastal city is also at risk of flooding. This is the first of two California cities on our list. According to preliminary calculations, he has at least 200 years before the sea starts to approach him. University of Southern California conducted a multilevel study in the Pacific Ocean and the predicted increase of 5 to 25 inches on the West Coast. This means that the coastline will be gradually eaten by sea, destroying buildings and entire cities in the coastal zone.
Since San Francisco is located near Los Angeles, then the permitted height of the water level here also is 3 meters. The city was founded on the peninsula is bent near the mainland. Because of the mountainous terrain to protect the area from the water is extremely difficult.
If the ocean rises 3 meters, will also be flooded coastal part of New York. The devastation caused by Hurricane Sandy and severe storms before him have already demonstrated that New York needs a new system of flood protection. Tragic tropical cyclone in 2012 killed 117 people in the United States and another 69 in Canada and the Caribbean. He set new records for the lines of the flooding in New York.
New Orleans - American city, the most tragic way related to losses from floods. Devastation along the Mississippi Delta in recent years have shown how vulnerable is actually a man who is faced with the elements. Hurricane Katrina virtually destroyed most of the city. Lowest levees of New Orleans are about 350 years before the ocean swallow them.
To destroy the South London require growth in global sea level by 5.5 meters. Myth of London, swallows the sea stirs the public for a long time. In fact, in this myth has a considerable share of reality. Why? The city itself is built around the mouth of the Thames, and the landscape, which is a big part of the city, especially in the south and east - a swamp. Currently, there are extensive defense system - Thames Barrier - protects against surges. London has about 375 years before going through Atlantis.
In Shanghai in stock is as much as 6.5 meters, which can occur after a disaster. Much like Los Angeles and San Francisco, Shanghai - only one of a number of Chinese cities, which threatens global sea level rise; Among other cities of Guangzhou, Hong Kong and Shenzhen. 6.5-meter rise could take about 400 years old and completely flood the city. It is worth noting that this is the worst case scenario, but even a small increase in a shorter period of time greatly harm the city. For example, if a half-meter rise by 2070 is a danger to 5.5 million residents. It is very poorly developed system of flood protection, and power are just beginning to think about it.
