Antarctic glaciers hide 138 volcanoes. Once the sea level erupts, coastal areas will be submerged.

People are often surprised that there are 138 active volcanoes buried under the Antarctic ice, thereby ignoring the fact that Antarctica is accelerating melting. You must know that global warming is affecting the thickness of Antarctica’s ice. Some scientists have discovered that since 1979 Since 2000, the ice in Antarctica has been melting at an alarming rate. Global warming has caused the melting rate of the Antarctic continent to increase by six times. Some researchers have found that from 1970 to 1990, the European continent has lost an average of 400 tons of ice per year. billion tons of ice. From 2009 to 2017, this number jumped to an average of 252 billion tons per year

Did you know? If all the Antarctic ice caps melt, the earth's sea level will rise 61 meters, and most coastal areas will be submerged. This is also a warning that humans often hear. The reason why people think this warning has little practical significance is because It is almost impossible for all the ice caps in Antarctica to melt in the foreseeable future. In fact, humans should not take this lightly, because scientific research has pointed out that the doomsday glacier, the Thwaites Glacier in Antarctica, is melting at an accelerated rate. , it may cause the earth's sea level to rise by 3 meters, which is enough to submerge most areas of coastal cities such as Shanghai, Tokyo, Bangkok, and Jakarta, thus causing huge disasters and economic losses

This The research comes from the International Thwaites Glacier Collaboration, which is composed of scientists from the United States and the United Kingdom. According to previous research, in the 2000 years before the 19th century, the earth's sea level has been very stable, neither rising nor falling. The fluctuations also appear to be very small. The difference is that starting from the mid-19th century, due to the burning of fossil fuels by humans after the industrial revolution and the emission of greenhouse gases into the atmosphere, the earth's sea level has followed signs such as the melting of ice caps and glaciers and the warming of seawater. It has continued to expand and is now about 20 centimeters higher than before the industrial revolution. Surprisingly, since 1990, the rate of sea level rise has almost doubled.

It can be said that the Thwaites Glacier in Antarctica is the key to this change. You must know that the area of ??Thwaites Glacier reaches 192,000 square kilometers, which is approximately equivalent to the area of ??the United Kingdom. Perhaps you already know that West Antarctica Glaciers are most obviously affected by climate warming, and Thwaites Glacier happens to be the cornerstone of other glaciers in West Antarctica, blocking the ice from other glaciers from flowing into the ocean. This means that once Thwaites Glacier melts, other glaciers in the Southwest Antarctic will have It may cause a chain reaction, causing thousands of horses to fall into silence and fall into the ocean. Looking at the Thwaites Glacier itself, you will find that its ice volume is not much. Even if it melts completely, it will only raise global sea levels by 65 cm

< p> Even so, this is a quite scary number. If other ice bodies rush into the ocean, it is likely to cause a sea level rise of 2 to 3 meters. This will undoubtedly be a disaster for most coastal cities around the world. A huge disaster, Thwaites Glacier has therefore become the most important research object for climate and glacier scientists around the world. Many scientists regard it as the most fragile iceberg in the world, and even received the nickname Doomsday Glacier. , when the United States used a new generation of satellites to conduct a comprehensive and systematic exploration of the Antarctic glaciers, people discovered a surprising event. It turned out that after the satellite penetrated the ice and detected a huge cave hidden under the Antarctic ice, The initial detection height of the cave is 300 meters, which can accommodate at least tens of billions of tons of ice. What is even more amazing is that this mysterious cave is located at the bottom of the Thwaites Glacier in West Antarctica.

The detection results show that this huge The ice inside the cave has basically melted, and it is currently seeping and melting to the upper levels. Some scientists pointed out that the size of the cave plays an important role in the speed of melting the surrounding glaciers. That is to say, as the ice melts around it, As this hole becomes larger and larger, more heat and more water will enter under the glacier, causing the melting rate of the glacier above to continue to accelerate. In fact, this huge hole hidden under the Antarctic glacier, It is just one of the more typical of the many cavities in Antarctica, because there are now many large and small cavities under the Antarctic ice. Obviously, they are all caused by the rising global temperature.

It can be seen that the earth's climate warming has formed a serious situation, and human beings' environmental protection has also reached a situation where it is urgent to delay. If human beings still do not pay attention to climate warming and allow it to develop. , which means that all the glaciers in the North and South Poles may melt. By then, glaciers in other areas of the earth will also be doomed. After all, the North and South Poles are the coldest places on the earth. If global glaciers melt on a large scale, the consequences will be devastating to the earth. The sea level of the world will rise by at least 50 meters. Maybe you are curious, what will be the consequences if the sea level of the earth rises by 50 meters?

This shows that most island countries will disappear, and the low-altitude areas of most coastal countries will be submerged. For example, Bangladesh, a country in Asia with an average altitude of less than 10 meters, may be completely submerged, and life will be More than 100 million people in the country will also be homeless and face serious survival problems. Eastern China, the northern plains of Europe and the coastal areas of Japan will also be flooded. Even the most prosperous cities in the world will be flooded. New York will also disappear due to rising sea levels.

Although Antarctic glaciers are melting at an accelerating rate, surprisingly, scientists have also discovered mysterious things in Antarctica that should not have appeared. Perhaps humans really should wake up. Recently, some scientists pointed out that Antarctic ice is There are 138 volcanoes hidden under the Antarctic. Once they wake up, the consequences will be disastrous. Few people know that the rising temperature in Antarctica will have a more serious and unknown impact on the recovery of the frozen layer. You must know that there are two important volcanoes on the earth. The frozen layer, one is the Siberian frozen soil layer, and the other is the frozen layer under the Antarctic ice. In these frozen soil layers, ancient bacteria and plants are frozen. Once the ancient bacteria and viruses recover, they may It can have a huge impact. It can be said that the melting of the glaciers in the Arctic and Antarctic means that prehistoric viruses are likely to surface.

Nowadays, human beings have clearly understood the importance of protecting the environment, but some people are still desperate for profit. Scientists generally believe that we who destroy the environment will eventually reap the consequences, and the revenge of nature is cruel. Yes, the most serious problem at the moment is the greenhouse effect, the emission of excessive greenhouse gases such as carbon dioxide, which has caused the earth to have a fever. In recent years, extreme climates have become more frequent, and the ecosystems on the earth are also suffering severe tests. Ocean changes Warmth has become a trend, and its harm is self-evident. However, all humans can do is delay its arrival. What do you guys think about this? Welcome to leave a message below in the comment area. Thank you for watching this video. See you in the next one.
