A terrifying study reveals entire cities are sliding towards the sea.

Climate change poses an increasing threat to all of humanity and causes many phenomena and disasters, but a new study has issued a terrifying warning that entire cities and coastal urban areas are gradually sinking towards sea level, which means that their millions of inhabitants will be threatened with drowning at any moment.

According to a report published by the British newspaper "Daily Mail" and reviewed by "Al-Arabiya.net", experts from the "Technical University of Munich" warned that the sunken cities on Earth are sliding towards sea level at an alarming rate.
In a new study, scientists found that land subsidence is doubling the rate of sea level rise in some coastal areas.

Researchers say what makes matters worse is that this affects the largest and most densely populated cities more than anywhere else.
Between rising sea levels and land subsidence, densely populated coastal areas experience a relative sea-level rise of about six millimeters per year on average. This is more than three times the global average relative sea-level rise of 2.1 millimeters per year.

Similarly, land subsidence nearly doubles the absolute rise in sea level of 3.15 millimeters per year, which measures the actual increase in ocean volume and height.
Dr. Julius Olsmann, the lead researcher from the Technical University of Munich, says this could "significantly amplify the effects of sea-level rise caused by climate change."
As the climate warms, the melting of glaciers and the gradual expansion of warm waters lead to a rise in the level of the world's oceans.

However, Dr. Olsman and his colleagues warn that the sea surface only shows half the truth.
Dr. Olsman says, "If we want to understand and respond effectively to rising sea levels along coastlines, we must monitor not only the ocean, but the land itself as well."
This is due to the combined effects of human activity and natural forces in submerging some of the world's largest cities in the ocean.

Dr. Olsman points out that the "enormous weight of cities" also contributes to urban areas sinking below sea level. As cities grow larger and skyscrapers rise, heavier buildings are constructed, compressing the soil beneath them and causing the city to gradually sink relative to its surroundings.

In addition to the rise in sea level caused by climate change, urban areas are experiencing a much faster rise in sea level than the rest of the world.
The countries experiencing the fastest relative rise in sea level include Thailand, Bangladesh, Nigeria, Egypt, China, and Indonesia, where sea level rises by 7 to 10 millimeters per year.

The United States, the Netherlands, and Italy are also experiencing exceptionally rapid rises, with sea levels rising by about 4 to 5 millimeters per year.
Because of the large impact of city size, many countries have experienced areas of severe land subsidence.

Jakarta, the capital of Indonesia, with its 42 million inhabitants and status as the world's most populous city, is considered the most vulnerable, as the sprawling metropolis is sinking towards the ocean at a rate of 13.7 millimeters per year.

It is closely followed by Tianjin, China, with a population of 13.8 million, which is experiencing subsidence at a rate of 13.5 millimeters per year.
Similarly, Bangkok, Lagos and Alexandria are experiencing much higher than average rates of land subsidence, at 8.5, 6.7 and 4 millimeters per year respectively.
