A number of major metropolitan areas are at risk of inundation due to global sea level rise. Global warming can be difficult to accurately visualize.
If you’re not directly threatened by sea level rise, water scarcity or wildfires, how do you know it’s really happening?
It may all seem a bit abstract. In this ARTICLE, we are going to look at the top nine cities that will be underwater by 2030 And wait until you see the top three, something you might not have thought of So don’t forget to watch till the end.
NUMBER - 9
Savannah, USA.
The city of Savannah, Georgia sits in a hurricane hotspot, but even without extreme weather events, the historic city can look swallowed up by the surrounding ocean. Both the Savannah Guyana River to the north and the Ogichid River to the south can spill into nearby wetlands, meaning that when hurricanes and flash floods hit the city, and by 2050, the city is predicted to experience once-in-a-century historic flood levels. Each year, the impact can become more severe.
NUMBER - 8
Georgetown, Guyana.
For centuries, Guyana’s capital, Georgetown, relied on the sea wall, or more precisely, a massive 280-mile-long sea wall, for protection from storms. This is because most shorelines are between 0.5 and 1 meter below high tide. About 90% of Guyana’s population lives on the coast. As you can see, the country needs to significantly strengthen its sea wall if the central areas of Georgetown are to avoid massive damage.
NUMBER - 7
 Bangkok, Thailand.
A 2020 study found that Bangkok could be the city most affected by global warming in the short term. The Thai capital sits just 1.5 meters above sea level and, like Venice, is sinking. Much faster, by about 2-3 cm a year.Â
But Bangkok is also built on very dense clay soil, which makes it more prone to flooding. By 2030, most of the coastal Tha Kam and Samut Prakan areas will be underwater, as will its main airport, Suvana Bumi International.
NUMBER - 6
 Kolkata, India.
Much of West Bengal has thrived for centuries due to its fertile landscape. But as the map shows, it has become a cause for concern in and around Kolkata. Like Ho Chi Minh City, the city can struggle during the rainy season because there is less land to catch rainwater. This map of possible scenarios in 2100 is even more alarming.
NUMBER - 5
 Ho Chi Minh City, Vietnam.
Climate Central’s map shows that Ho Chi Minh City’s most vulnerable areas are its eastern districts, particularly the flat, heavily built-up wetlands of Thu Thiam. But it also seems likely that the city will face increasing threats along the MÃ Cong Delta. Although downtown Ho Chi Minh City is unlikely to find itself underwater by 2030, it will almost certainly be more vulnerable to flooding and tropical storms.
NUMBER - 4
 Venice, Italy.
In the near future, Venice faces a twin threat. Sea level is rising and the city is sinking by 2 millimeters per year. The capital city of Venice has already been hit by severe flooding, and climate change is likely to increase the frequency of high tides that submerge it. Like New Orleans, Venice has a flood defense system in place, but as the crisis worsens it will become more difficult and expensive to maintain.
NUMBER - 3
 New Orleans, USA.
Look at those sharp, thick gray borders on the map around the center of New Orleans. It was the life system of the city that protected it from the curse of the Red Building from Lake Maurepas to the north and Lake Salvador and Little Lake to the south. Without these defenses, New Orleans would be seriously threatened by sea level rise, But even with them, the damage looks catastrophic. Biloxi and Jean Lafitte wildlife preserves look particularly vulnerable. On the map, both appear almost completely submerged.
NUMBER - 2
 Basra, Iraq.
Basra, Iraq’s main port city, is located on the Shat al Arab, a large and wide river that flows into the Persian Gulf. Due to the complex network of canals and streams, as well as neighboring wetlands, Basra and its surrounding areas are particularly vulnerable to sea level rise. As if that wasn’t alarming enough, Bossa already suffers significantly from waterborne diseases, so increased flooding poses an even more significant threat.
NUMBER - 1
 Finally, Amsterdam, Netherlands.
One reason they are called the Low Countries. The cities of Amsterdam and Rotterdam and The Hague are low, flat and close to the North Sea. The Dutch are famous for their flood defences. These sea level projections suggest that the country’s system of dikes, dams, barriers, levees and flood gates will become more necessary in the coming years. And there you have nine cities that could be underwater by 2030.
