Dozens of cities around the world are sinking?

Earlier this week, Indonesia officially announced that it would “move the capital” in 2024. One of the important reasons for the implementation of this grand project is that the country’s current capital, Jakarta, is already a “dangerous city” with an average annual settlement of 25 centimeters. Ranked first in the world. However, Jakarta is not the only city in the world that is sinking. As the climate changes, the academic community warns that in the next few decades, dozens of major cities or parts of the world will sink or “disappear as a whole”, and thousands of coastal communities will be unable to live. Protecting the environment is an urgent task.

At the end of the 21st century, many cities in the United States will be flooded

According to the US Business Insider magazine, global sea level will rise by about 2.43 meters by 2100 according to the current melting rate of polar glaciers. By then, many cities in the United States will pay a heavy price for this – most of them have suffered from floods in the past, and the future development trend is even less optimistic.

The city of New Orleans, located on the Gulf Coast, is low-lying and built in the estuary of the Mississippi River. The city is particularly passive in the face of floods. In fact, the city has not recovered from the hurricane disaster in 2005.

According to a study by the National Aeronautics and Space Administration (NASA), New Orleans has seen a significant sinking trend in recent years, with a settling rate of about 5 centimeters per year. It is understood that some areas of the city are below 4.5 meters below sea level. According to this development, large areas of the city will be submerged in 2100.

Similar to New Orleans, Atlantic City, New Jersey was also devastated by hurricanes: 70% to 80% of the city’s area was swallowed by floods when Hurricane Sandy transited in 2012, and nearly 250 meters of water in some areas . Experts speculate that the natural disasters facing the city in the coming decades will be even more fierce. More worrying than the fate of Atlantic City is Charleston, a port city on the southeast coast of the United States: local media asserted more than 10 years ago that the city will become a “half-inundated ghost town” in 2050.

Compared with these “difficult brothers and sisters” located along the coast, the settlement of the US space city Houston is more due to human factors. According to the Houston Chronicle, some parts of Houston have an average annual subsidence of about 5 centimeters. The main cause is the excessive extraction of groundwater, which has led to the depletion of underground aquifers. In addition, the US capital does not guarantee absolute safety: According to the US Geological Survey, Washington will settle 15 centimeters in the next 100 years.

According to the report, the United States Union of Concerned Scientists has reached a more pessimistic conclusion about the major issue of “the United States sinking”: the organization believes that it is not necessary to wait until the end of the century, the country will have 30 cities in 2060 or so. Under water, 300,000 households will be directly affected, and direct economic losses will exceed $117 billion.

The global warming is 3°C, and the Asian metropolis is “the most injured”

At the UN climate conference held in recent years, “heating 3°C” is one of the key words of related issues. The academic community expects that global temperatures will rise by about 3 degrees Celsius by the end of the century, and the rate of increase and speed far exceeds previous expectations, making important international agreements to curb climate change seem particularly weak in the face of this indicator. The Climate Center of the US non-profit meteorological science information agency once predicted that a global warming of 3 °C will directly affect 275 million people, and the loss of densely populated Asian metropolises will be particularly prominent.

According to the mathematical calculations of scientists, in the future “3 °C era”, Osaka, the economic center of the Kansai region in Japan, will be inundated by the sea, and 5.2 million residents will be directly affected, with economic losses of up to 1 trillion US dollars. China’s “Pearl of the Orient” Shanghai also has huge flood hazards: foreign media said that the Shanghai center will suffer a “large area” in the “3 °C era”, the affected population will reach 17.5 million, even some landmark high-rise The building is also not immune. The British “Guardian” said that in fact, since 2012, the Shanghai government has begun to deal with flood hazards, not only built the country’s largest deep drainage system, but also invested more than 40 billion yuan for the Wuhu River flood discharge project in Taihu Lake. The Dhaka, the capital of Bangladesh, is no less dangerous than Jakarta: the water level in the Bay of Bengal is 10 times the global average.

In fact, from Latin America to Africa, to developed Europe, there are hidden dangers of “land subsidence” all over the world. Some media said that in the face of “the anger of nature”, no region on the planet can be immune to it.

Global warming is a conspiracy theory?

Although the dangers of climate change have received global attention, some people think it is a bit exaggerated. As early as the beginning of the 21st century, Republicans in the US Congress considered global warming to be “pseudoscience.” At that time, Senator Inhoff claimed that the politicians who supported the “Kyoto Protocol” were guilty of ghosts, and the ultimate goal was to achieve “global governance.” There is also a widely spread view that scientists deliberately create this kind of argument in order to obtain “research funding.”

In addition, there are also public opinion that the academic circles have exaggerated the depiction of the future “end-of-world scene”. After all, many countries are also actively responding, and the ruling class is not allowed to let the “land sinking.”
