If all the glaciers on the earth melt, there will be 20 million cubic kilometers of water in the ocean. What concept?

When it comes to global warming, this issue is a cliche. Everyone has heard of it. Everyone knows what it is, but only a few people are taking measures to prevent this huge problem from happening. What most people don't know is that this unsolved problem is getting bigger and bigger. If the greenhouse effect continues to develop, all glaciers will melt. What will happen if all the glaciers melt? In the near future, what kind of situation, what kind of life and what kind of new map are waiting for us? Today we will talk about this problem.

Due to global warming, the melting rate of glaciers has increased dramatically. According to some scientists' predictions, in 80 years, the world will undergo great changes and the world map will be rewritten. If mankind continues to use all the current coal, oil and natural gas reserves, the increase of carbon dioxide emissions is inevitable. The increase of carbon dioxide in the atmosphere will cause the average temperature to rise to 27 degrees Celsius, and the current value is about 14 degrees Celsius. In many areas, the temperature will become terrible and many territories will be banned from living.

At that time, the shape of the mainland will be greatly changed, many big cities will be submerged, North America will flood the east coast of new york, Washington, Boston and all cities along Florida and the Gulf of Mexico, the California hills in San Francisco will become islands, and Cuba will almost disappear, while in South America, the Amazon River basin in the north and the Paraguay River in the south will become bays, destroying the Buenos Aires coast of Argentina and most parts of Paraguay.

The mountainous areas will become coastal areas. Compared with other continents, Alexandria and Cairo in Africa will be completely submerged. However, due to the high temperature, most parts of the continent will be uninhabited. China and Cambodia may suffer the most, because most of their populations are concentrated in coastal cities, and half of our territory may be swallowed up by the sea. As predicted by the data, scientists have been calculating for a long time that the water stored by glaciers will raise the water level of the world's oceans by 65 meters. In order to prevent tragedy, we should understand the complexity of the whole process and explore ways that may affect the situation.

According to the data, the volume of all ice on the earth can be melted into about 20 million cubic kilometers of water. If we add it to the volume of the world's oceans, then this amount of water can flood most islands and significantly reduce the land on the earth, and the whole world will change. The most serious problems await small islands, coastal areas, cities and countries below sea level. Due to the flooding of seawater, most of Asia, China, Japanese, Bangladeshi, Indian and British will be submerged. In Europe, parts of Holland, Venice and Denmark will completely disappear under water. The territories of North and South America, as well as the places where most people in Australia live, will be submerged.

Water will wipe Uruguay and Paraguay from the earth, and astrakhan, Kaliningrad, Vladivostok, Sochi, Arkhangelsk and St. Petersburg will be the first Russian cities to be submerged. The whole coastal area will also be flooded. Africa suffered the least. But rising temperatures will make these areas uninhabitable. As for the North Pole, it will basically disappear without the shackles of ice. At present, the topography of the continent where the ice sheet is located is lower than the sea level, and the deepest point is 2780 meters. Even the Arctic mountains hidden under a kilometer and a half of ice can only stay underwater.

But there is also a more pessimistic view about the melting of glaciers. British mathematicians predict that the North Pole will melt in 80 years. They believe that human attempts to simulate the climate by reducing greenhouse gas emissions to prevent warming will not produce the expected results. Mathematicians have calculated that the allowable heating rate stipulated in the Paris Agreement is 1.5 degrees. Even if all countries abide by the regulations that allow carbon dioxide to be discharged into the atmosphere, the ice will completely melt in a few decades!

Of course, the calculations of the above-mentioned British scientists are mainly based on the greenhouse gas theory, without considering other important factors that may affect the global warming process. However, not only the territory and agricultural land are threatened by complete immersion, but also the salt concentration in the world's oceans will decrease and the pH level will change, which will lead to the extinction of most animals and plants in the underwater world. Therefore, a large number of deaths of birds and animals will begin, which will lead to the interruption of the relevant food chain. This situation will lead to a food crisis, and famine will mainly occur in countries and regions that traditionally rely on the sea for their livelihood.

In addition to hunger, human beings also face other social problems, such as the loss of shelter and the massive migration caused by the deterioration of physical and mental health. In fact, this is not only related to people's well-being, but also to the existence of the whole human civilization. The existence of human civilization itself is a problem. China's most densely populated and developed Shanghai, Singapore and Beijing will be submerged, leaving only a few sparsely populated mountainous areas, most Indian coastal cities will also sink, Cambodia will sink, leaving some island cities, Sydney and Melbourne will sink, London will disappear from the earth's surface, and the Gulf of Finland will reach Novgorod and Pskov.

The water levels of the Black Sea and Caspian Sea will rise sharply with the Aral Sea, the Caucasus will be separated from Asia and Crimea, it will no longer exist as a peninsula, it will become a real island, everything will be submerged, and astrakhan will go deep into the water. The melting of Antarctic glaciers will bring a series of adverse effects, which will eventually leave an archipelago composed of large and small islands. Before all the ice melts, the Atlantic ocean current may also change due to the gradual desalination of the ocean. In fact, the climate zone of the earth will also change, because ocean currents will bring cold water to the equator, while warm water will flock to the poles. In other words, due to the continuous inflow of fresh water into the ocean, the Atlantic ocean current will gradually change, and the melting of glaciers will make traditionally cold countries and regions in a tropical climate.

With the melting of ice caused by global warming, everything will change, and natural disasters such as droughts and hurricanes will become more frequent. Fortunately, all this is the future decades later. I believe that everything will change as long as human beings put it into practice. what do you think? Welcome to leave your opinion!
