More than 300 scientists have witnessed the extinction of the Arctic in 389 days of scientific research

When it comes to the Arctic, many people have the impression that the winter there is long and cold. Surrounded by glaciers and oceans, it is a vast and mysterious pure land without human survival. With the change of ecological environment in recent years and the global warming, unprecedented changes have taken place in the Arctic. The ice sea begins to melt completely until it disappears, and the polar bear is on the verge of extinction. In order to explore the current situation of the Arctic, more than 300 scientists have conducted scientific research in the Arctic for 389 days and witnessed the extinction of the Arctic.

The Arctic is dying out so fast that scientists are terrified

In the eyes of most people, they tend to ignore the existence of polar regions and like to discuss whether it is cold in the north or cold in the south. However, in the eyes of many scientists, they are keen to explore the polar regions. In many news media reports, we often see that scientists often go to Antarctica for scientific research. The reason why they often go to Antarctica for scientific research is that Antarctica is easier to reach than the Arctic.

However, with the increasing global warming, scientists around the world are also restless. Will the Arctic be seriously affected? Did the glacier melt rapidly? Nearly 300 scientists from 19 countries, including Britain, China and France, participated in the Arctic scientific research mission, which raised nearly 153 million pounds. This time, the number of members of the scientific research team was large and the scale was the largest. Starting from Norway on September 20, 2019, scientists are about to spend more than a year on this big ship. During this period, scientists from all over the world have a clear division of labor, mainly studying the climate, ecosystem, soil, ice layer, etc. of the Arctic. This huge ship has only become an Arctic scientific research station temporarily built by scientists.

1. The ecology of polar bears has deteriorated to an extreme degree

In this Arctic expedition, scientists from all over the world felt the serious impact of Arctic climate change on Arctic organisms. Late one night, 20 polar bears, many of them juveniles, gathered near the scientists’ boat. Scientists understand that the main reason why these polar bears approach human areas regardless of danger is that they are too hungry.

Scientists began to feed polar bears continuously. In the long run, these polar bears have become dependent on the sites where they are stationed and refused to leave for a long time. We should know that the main way for polar bears to hunt seals is to wait in ice caves. Now that the area of Arctic ice is decreasing or even disappearing, it is more difficult for polar bears to hunt seals. Scientific research team members have carefully observed these polar bears and found that they have become as thin as wood. If they do not take corresponding measures to intervene in time, these polar bears will face gradual extinction.

2. The thickness of the Arctic ice has been greatly reduced, and it may be completely ice-free in the next few decades

It’s hard for scientists to imagine that the Arctic sea ice area in the summer of 2019 almost broke the record, ranking the second from the bottom in 42 years, the year with the least sea ice. Scientific researchers predict that in the next few decades, the Arctic may be completely ice-free and become a vast sea. In fact, as early as 2012, the Journal of the National Academy of Sciences, an authoritative American Journal, published the findings of a group of scientists. At that time, the view was that the Arctic might be ice free by 2054. Thus, it can be seen that the prediction of scientific research team members is not unreasonable. If we say that the Arctic sea ice will completely melt and disappear in the future, it will have a huge impact on Arctic creatures. Polar bears can not survive. The only way out is to helplessly seek help from human beings!

How will the Arctic disappear in the end?

1. All the ice and snow melted and the sea ice gradually disappeared

The melting of ice and snow in the Arctic and the gradual disappearance of sea ice may be the key factor for the final extinction of the Arctic. Since mankind entered the era of industrial revolution, the rapid development of science and technology, the continuous emission of nitrogen dioxide and other greenhouse gases into the atmosphere, resulting in the rising global temperature, and then the Arctic ice and snow has undergone earth shaking changes, from the thick snow, to melt away, in the next few decades, the Arctic has no ice cover, all melt into sea water Even in winter, there is little ice, and even the ice is only a thin layer. The melting of all this ice and the gradual rise of sea level is the direct cause of the disappearance of the Arctic.

2. Fires occur frequently in the Arctic Circle, and the fires that cannot be put out make the Arctic die out completely

It seems that human and nature are two swordsmen fighting. The closer human forces, the more serious nature’s defense. Nature will keep on fighting back at the same time of defense. For example, in September 2019, a large-scale forest fire broke out in Australia. The fire lasted for five months and lasted more than 150 days. The burning area was more than 10 million hectares, thousands of acres of land were burned, and hundreds of millions of animals were displaced. The large amount of carbon dioxide in the accessories brought by the fire will further accelerate global warming and aggravate global warming greenhouse effect.

As the saying goes, good fortune comes in two directions, and disaster never comes alone. The rapid melting of glaciers in the Arctic is directly related to the fire. In the Arctic Circle, Siberia once had one of the most serious fires, which accelerated the melting rate of glaciers. If there will be a steady stream of fires in the near future, it will directly make the Arctic die out!

3. The last known ice shelf in the northern hemisphere disappears, and the Arctic enters “advanced cancer”

It is worth mentioning that the ice shelf of Ellesmere Island is the northernmost island in the Canadian Arctic region, which is located to the west of Greenland and to the north of Baffin Island. The original area of 290 square kilometers, with undulating ridges and valleys terrain, with typical characteristics of the Arctic ice shelf. Now the ice shelf on Ellesmere Island has collapsed, which means the disappearance of the last known ice shelf Lake in the northern hemisphere. The geographical feature of this lake is that the fresh water is blocked by the ice shelf and floats on the sea water. What does it mean that the last ice shelf in the northern hemisphere disappears? That is to say, the Arctic has entered the “advanced stage of cancer” and is one step closer to its final demise.

At present, what is the state of the Arctic climate?

According to the relevant data passed by the scientific research team, the Arctic is warming twice as fast as the whole earth, which can be said to be speeding. What are the consequences of speeding? For example, a car speeding in the city has reached 120 mph. When the front side encounters an obstacle, it needs to brake urgently, and the consequences are appalling. So similarly, in this speeding state, the earth’s temperature rises rapidly, and some rare cyclones appear in the Arctic, which leads to this extreme climate phenomenon in the Arctic.

What is the impact of the complete extinction of the Arctic on human beings?

1. The area of ecological environment island is gradually reduced or inundated

At present, the ecosystem of the Arctic circle has undergone obvious changes. If there is a moment of extinction and collapse, the most direct impact on human beings is that the sea level rises, the island area shrinks or is submerged. The problem of sea-level rise can be said to cause concern for future life, because most of the world’s major developed cities are offshore areas, and the height of the coastline is relatively low. However, sea-level rise will impact these areas, causing more and more serious problems. For example, the entire Atlantic coast of the United States will disappear, Florida and the Gulf Coast will disappear, the hills in San Francisco will become islands, and San Diego will disappear forever.

For China, the coastal areas will also be directly affected, or even submerged. Thus it can be seen that the extinction of the Arctic and the rise of sea level make the land area where human beings can survive smaller and smaller, and one third of it is desert. If the land area continues to decrease, it may be an ecological crisis for all mankind.

2. Arctic vanishes, frozen soil melts, virus and bacteria “see the sun again”

In an article published in the journal Current Biology, scientists found a 57000 year old body in the Arctic permafrost. This corpse is the mummy of a wolf cub. This major discovery has also caused great concern for scientists, that is, with the aggravation of global warming and the continuous melting of permafrost, some ancient rare viruses and bacteria may break out of the ground and see the sky again. For example, lethal and disfigurement smallpox will revive again, and seasonal dengue fever or Zika virus may appear in Europe.

Although we will see these situations in many disastrous movies, if the Arctic perishes, the ancient virus will wake up from the frozen soil and become a reality. The panic novel coronavirus pneumonia has claimed more than 1 million 130 thousand lives so far. Some people speculate that this virus may come from frozen soil. With the expansion of human ecological footprint, the Arctic is melting and disappearing faster, and we may cause epidemics in other ways. It is worth mentioning that the number of bacteria and viruses latent in permafrost can not be estimated, but the more important problem is that they are very dangerous. On this issue, scientists are also scared.

3. Arctic species disappear, human beings no longer have them

With the aggravation of global warming, the Arctic has finally disappeared, and the species living in the Arctic will be doomed. For example, the most common polar bear has completely disappeared from the view of human beings. After the ecological balance is broken, it is also a kind of counterattack from nature for human beings. As for the consequences of this counterattack, we do not know.

As the most advanced life on the planet, what we human beings need to do now is to protect the ecological environment, reduce the greenhouse effect, and green and low-carbon travel. Although the current Arctic is not critical, its situation is not optimistic. Paying attention to the change of the Arctic ecological environment means paying attention to the future of human beings. At this critical moment, we should realize that everyone is responsible!
