By the end of the century, one of the largest cities in the United States could be inundated

There are 33 cities in the world sinking at least 1 cm per year. Houston, Texas, for example, is 1.95 cm closer to sea level every year world economy.

The World Economic Forum (WEF) According to his research, many large cities are sinking faster and faster and are approaching sea level.

Coastal cities such as Miami in the United States and Guangzhou (Canton) in China may face massive flooding in the future due to rising water levels as a result of climate change, while devastating floods are expected in other cities. In addition, some of the world’s major cities are sinking at a rate faster than the sea level around them. The cause of subsidence can be found mainly in sedimentation, when underground changes occur, mainly due to the use of groundwater. In the case of densely populated areas, the massive presence of residential buildings and industrial production only aggravates the situation.

As a result of subsidence, the vast majority of cities sank several millimeters per year.

It is estimated that at least 33 cities fall by more than one inch per year, five times the sea level rise. The The fastest sunken cities They are concentrated in South and Southeast Asia, for which they are therefore forced to constantly adapt. For example, Indonesia is moving its capital from Jakarta, a city of 10.5 million people, to the newly built island city of Borneo, 2,000 kilometers away, in part because Jakarta is sinking heavily. Experts also noted that the process cannot be stopped, only slowed down. In Jakarta, the value of 28 cents per year has been reduced to 3 centimeters per year thanks to the efforts made.

The city of Houston in Texas is the only one among the top 10 cities not to be found in Asia. At worst it is Tianjin, China, where it decreases by 5.22 cm annually.
