In fact, urban subsidence is an important crisis faced by coastal cities in many countries. Because the city sinks, the sea rises and the sea level rises. Eventually, some buildings or some transportation facilities will be built, so a large number of people will move to this area. So the sinking of the city is a terrible thing, because if the city continues to sink, it means that the city may be eroded by seawater and gradually sink to the bottom of the sea.

Seeing this, you may have questions. What caused the city to sink? In fact, this kind of reason is varied, and it is the result of the comprehensive action of many factors, and not one factor can work alone.

Influencing factor one: global warming.

Global warming is an important reason for the sinking of some coastal cities, because the current carbon emissions are gradually increasing. And the greenhouse effect of wild boar is gradually emerging, so in some. The temperature in cold areas is also rising gradually, especially the glaciers in the Antarctic and Arctic are gradually melting.

If glaciers melt, it will bring a problem, that is, sea level rise. If the sea level continues to rise, some islands may be submerged. And some coastal cities may sink to the bottom of the sea, which is possible, so it is still terrible to think about it carefully. This is why some residents in coastal cities began to move, because they are now willing to start rising, and their housing problems have emerged.

This is an important reason for the sinking of the city. In fact, the sinking of the city is relative, because the sea level has risen, so the city feels sinking. In fact, the main reason is the sea level rise caused by global warming.

Influencing factor 2: sea level rise

In fact, sea level rise and global warming are the same thing. It is because of global warming that the glaciers in Antarctica and the Arctic are gradually melting. After melting, the sea water increases, and the sea level rises after the sea water increases, and some coastal areas may be submerged. This is a complementary thing, and the two are positively related.

It is the rise of dolphins that has created some coastal areas. There is this phenomenon of being submerged. In fact, if you look closely, it is mainly because the rising sea level has led to the illusion that the city is submerged.

Seeing this, you may still have questions, why are all American cities flooded, and why are urban collapses mainly concentrated in the United States?

In fact, this is also easy to understand, because the land elevation in the United States is not too high, and the average elevation is no more than two kilometers. This means that in some coastal cities in the United States, their residents live in some relatively low-lying areas. So if the sea level rises, the place where they live may be flooded. So in this case, these coastal residents have to be forced to move out of their hometown. Go to some high places.
