What will happen to the earth if sea levels rise five hundred meters? Can you talk about it?

Due to global warming and the melting of polar glaciers, sea levels have risen by approximately 24 centimeters in the past 100 years. So if the sea level suddenly rises by 500 meters, will the earth be submerged? There is a lot of ice on the earth, but according to calculations, even if all the ice melted overnight, it would only cause sea levels to rise by about 70 meters. This would flood all coastal cities and force more than 3 billion people to leave their homes for higher ground. So the ice on Earth cannot raise sea levels by 500 meters unless the ice increases sevenfold.

Once the sea level rises 500 meters, the disaster caused will be absolutely devastating. Compared with such disasters, the tsunami floods are nothing to mention. So could such a disaster flood the earth? The average altitude of the land on the earth is about 840 meters, so many places will not be submerged, but Australia will be completely sunk and covered by 200 meters of sea water. The same fate is Europe, and most areas will be submerged. There are also many countries whose altitude is less than 500 meters. Countries such as Denmark, the Netherlands, the United States, Japan and Canada will completely sink to the bottom of the sea. Only some higher peaks may be exposed to the sea. The bustling coastal areas Areas will be flooded, so which ones are safe?

At this time, Africa will become the first choice for human immigrants. This continent is located at an altitude of 600 meters and will not be submerged by sea water. Our country, China, also has a very high altitude, especially in the plateau area. At that time, we will become the largest and most prosperous country in the world. But this is not the end, but just the beginning. As coastal flooding engulfs cities and countries, potentially killing billions, a handful of survivors make their way to higher altitudes, but the disaster doesn't end there.

The melting of glaciers and the dilution of seawater will cause some ocean currents to stop flowing. The average temperature on the earth will directly drop, and may even lead to a small ice age. When the seawater rises 500 meters, there will be almost no food to eat. The barren land cannot grow enough food, and all animals on land are drowned. Marine creatures will not be spared, because they are used to living in seawater with high salt concentrations. Once the glaciers melt, both seawater and seawater will be so large. Most marine life will die or even become completely extinct. There are also water resources. Seawater will pollute the groundwater system and a large amount of fresh water. Unless a seawater desalination system is applied on a large scale, you can only look at the seawater and die of thirst. By that time, the earth will be the well-deserved blue planet, almost completely covered by sea water.
