World Atlas reports that coastal cities that are located at low altitudes that were prone to flooding in the past might suffer in the near future from the rise of sea levels.


Miami in the USA is one of the potential ill-fated cities that could soon be underwater as a result of human-induced global warming.

Its sea levels are rising at one of the fastest rates in the whole world, experts say, and current floodings are already creating problems for the freshwater system and for various buildings and structures.

In order to increase inhabitability for the residents, Miami officials should raise their buildings further above and strengthen their bases.

Nevertheless, should climate change continue to worsen over time, Miami could be in big trouble by mid-century.

One particular environment expert says that "there's virtually no scenario under which you can imagine [Miami] existing at the end of the century."


Amsterdam is another city, this time in Europe, that confronts itself with issues regarding rising sea levels and the danger of flooding.

This is because the city's various canal systems are linked to the sea, so any rise in sea level will automatically affect the navigation system within the urban settlement.

This is further accentuated by the fact that the Netherlands itself is a country that mostly sits below sea level, which means that it was able to get out of harm's way so far by using dams for cities such as Amsterdam.

Over the course of history, big flooding did serious damage to the country's buildings and killed many thousands of people and animals.

Until climate change is stopped, which may take some good number of years to happen, Dutch authorities have to constantly keep the dams and drainage systems under permanent maintenance and to upgrade them, whenever necessary.


Venice is one of the most well-known cities in the world, thanks to its canal systems that are packed with gondolas and its beautiful Italian architecture.

If you wanted to visit this beautiful city, you should do so soon, because it may be underwater by next century. This is because it is currently sinking at a rate of about two millimeters per year and is constantly threatened by high tides and flooding.

The worst flooding event in the recent history of the urban settlement took place in 2018, when severe storms caused the worst flooding in the last decade and the following year, in 2019, 90% of Venice was flooded.

Back in 2003, authorities started building a barrier that was designed in the 1980s, but it has not been completed to this day and if climate change issues continue to persist, it will likely not matter whether it will be built or not.

Still, protecting the city should be a priority for the officials, who must try to keep Venice afloat with all possible means.

New Orleans

The city of New Orleans in the USA has some of the richest history and culture in the country and was highly influenced by the French.

As some parts of the city sink at a rate of five centimeters per year, NASA experts said in 2016 that the entire city will be underwater by 2100.

When it was first developed at the beginning of the 19th century, the city was entirely above sea level, although by 1935, 30% of it was submerged already. Nowadays half of New Orleans is below sea level with some areas being so low that they can become irrecuperable in the next couple of years.

Biloxi and Jean Lafitte National Parks seem to be the most affected by the situation and authorities must constantly find new ways to keep the city and its surroundings afloat.


The popular touristic attraction located in the Indian Ocean is another place on Earth that is in danger of vanishing under the sea. Its 1.200 islands are home to the population of 540.000 people and the tourists that come here looking for the crystal-clear waters.

Researchers warn that climate change could end Maldives' existence, as 77% of the place could be gone by next-century if sea levels are to rise even by just 1.5 meters.

These are just a few of the many places in the world that are threatened by global warming and rising sea levels and that could be gone soon, unless we act to stop temperatures from climbing further.
