Cities that could get submerged by 2030!

Several major cities are at risk of being flooded as sea levels rise throughout the planet.

It might be tough to visualize global warming accurately. As the world warms and pollution goes unchecked, these big cities throughout the world may find themselves underwater as sea levels rise.

1. Amsterdam, the Netherlands: The cities of Amsterdam, Rotterdam, and The Hague are low, flat, and near to the North Sea. The Dutch are known for their flood defenses, and based on these sea-level estimates, it appears that the country’s dikes, dams, barriers, levees, and floodgates will become even more important in the coming years.

2. Bangkok, Thailand: According to 2020 research, Bangkok might be the city most affected by global warming in the short future. The Thai capital is barely 1.5 metres above sea level and is falling at a rate of approximately two to three centimetres each year. However, Bangkok is constructed on relatively solid clay soil, making it even more vulnerable to flooding. Most of the coastal Tha Kham and Samut Prakan regions, as well as the city’s principal airport, might be submerged.

3. Basrah, Iraq: Iraq’s primary port city, is located on the Shatt al-Arab, a vast and broad river that flows into the Persian Gulf. Basrah and its environs are particularly vulnerable to rising sea levels due to its extensive network of canals and streams, as well as nearby wetlands. As if that wasn’t bad enough, Basrah already has a high rate of waterborne infections, making increasing floods even more dangerous.

4. Georgetown, Guyana: For decades, the capital of Guyana has relied on sea walls or, more precisely, one massive, 280-mile-long sea wall to keep hurricanes at bay because the majority of the shoreline lies between 0.5 and one metres below high tide. Guyana’s coastline is home to 90% of the country’s population and the country’s sea wall will need to be significantly strengthened if Georgetown’s core sections are to avoid major damage.

5. Ho Chi Minh City, Vietnam: The eastern districts of Ho Chi Minh City are the most vulnerable, notably the flat, densely built-up marshland of Th Thiêm. However, it appears that the city would face rising threats near the Mekong Delta. While Ho Chi Minh City’s central business district is unlikely to be flooded, it will almost surely be more vulnerable to floods and tropical storms.

6. Kolkata, India: Because of its lush topography, most of west Bengal has prospered for ages, but this has become a major source of concern in Kolkata and its environs. During the monsoon season, the metropolis, like Ho Chi Minh City, may struggle since precipitation has less ground to flow off onto.

7. New Orleans, USA: The city’s levee system keeps it safe from the swarms of red buildings that come from Lake Maurepas in the north and Lake Salvador and Little Lake in the south. New Orleans would be gravely endangered by increasing water levels if those defenses were not in place, but even with them, the devastation appears to be catastrophic. The Biloxi and Jean Lafitte nature preserves appear to be particularly endangered since they appear to be almost completely submerged.

8. Savannah, USA: Savannah is located in a hurricane hotspot, yet the historic city might be eaten up by the sea on all sides even if no catastrophic weather events occur. The Savannah River to the north and the Ogeechee River to the south might potentially pour into surrounding wetlands, making the effects of storms and flash floods even more severe.

9. Venice, Italy: Venice confronts a double threat in the foreseeable future: increasing sea levels and the city itself sinking by two millimetres every year. Climate change is predicted to increase the frequency of high tides that submerge the Venetian city, which has previously been affected by severe floods. Venice, like New Orleans, has flood-defence systems in place, but they will become more difficult and expensive to maintain as the problem develops.

Of course, there are several factors at play, but what we’re interested in is what may happen if pollution continues on its current path. Between now and 2030, a lot may happen. We might construct flood defenses, modify our cities, and, ideally, take substantial measures to limit global warming if the COP26 negotiations proceed as planned. But if none of that happens, the following are the possible consequences: nine cities might be completely submerged or partially submerged within a decade.
