So what does the "new Arctic climate" mean? What impact will the emergence of a new climate have on the Arctic and the world?
What is the "New Arctic Climate"? Monitoring data show that in the past decade, the level of Arctic sea ice has been decreasing year by year, reaching a record low this year. At the same time, the average temperature in the Arctic is also rising, which has also created a record high. Therefore, scientists at the National Center for Atmospheric Research in the United States want to know whether the climate in the Arctic has changed in a certain mode under such circumstances, and whether it is very different from the climate expected in the past.
So they collected the monitoring data of the Arctic climate in recent twenty years, and then established a mathematical model by computer, which used a lot of statistical principles. In the process of building the model, scientists mainly consider three factors, namely, the sea ice range in late summer, the average temperature in autumn and winter and the change of precipitation days. Finally, through hundreds of computer simulations, it is found that the Arctic climate has deviated from the original forecast range and new climate phenomena have appeared.
Laura Lanzuan, the lead author of this study, said that the current climate change in the Arctic is so rapid that a series of prediction models established by scientists in the past seem to be invalid. Now it is more difficult for us to predict how the Arctic climate will develop in the future. Not only that, the researchers also predicted the changes of Arctic sea ice based on computer simulation. The forecast results show that if the greenhouse effect continues, the Arctic sea ice will probably disappear completely by the end of this century.
What impact will the emergence of a new climate have on the Arctic?
The new climate is a climate phenomenon under the background of greenhouse effect, so its impact on the Arctic is exactly the same as that caused by greenhouse effect. First of all, the new climate will increase the temperature in the Arctic, leading to the accelerated melting of a large number of sea ice. The melting of sea ice will lead to the rise of sea level, which will lead to the inundation of low-altitude land or islands, followed by a series of chain reactions. In addition, the melting of sea ice will also lead to the loss of habitat for Arctic creatures.
Among them, the most affected animal should be the polar bear. Most people think that the polar bear is a bear with snow-white hair, but the photos taken by scientists in the Arctic in recent years are very shocking. Many polar bears have become skinny and their range of activities has been greatly reduced. The reason for these phenomena is that a large amount of sea ice melts, which hinders the hunting of polar bears and reduces the space for activities.
According to the prediction of the National Center for Atmospheric Research, with the disappearance of Arctic sea ice, wild polar bears will be extinct, and humans can only see polar bears in zoos and museums. The occurrence of the new climate will also drive the Arctic region to release a large amount of methane, which will aggravate the greenhouse effect. Scientific research shows that the Arctic is the main methane storage base in the world, and methane is generally stored in ice sheets and frozen soil. If all these ice sheets and frozen soil melt, a lot of methane will be released into the atmosphere.
As we all know, carbon dioxide is the largest greenhouse gas, and methane is the second largest greenhouse gas. The release of methane from the Arctic will further aggravate the greenhouse effect and make it more difficult for human beings to cope with climate warming in the future. In addition, the emergence of a new climate has also led to the rediscovery of many creatures tens of thousands of years ago. What creatures are there?
What does it mean for ancient creatures to see the light of day again?
A few years ago, some scientists dug up the remains of an ice age mammoth on an island called Lyakhovsky in the Arctic Circle. It is understood that they did not actively look for this mammoth at that time, but saw some mammoth remains exposed to the ground during outdoor scientific research. This is because the ice sheet in this area has melted in a large area. In 20 19, researchers found the body of a "direwolf" on the bank of Yakutia.
It is understood that most of the fur and teeth were still preserved on the remains of direwolf at that time. According to chronological analysis, this wolf has a history of 40,000 years. During the same period, researchers also found a 42,000-year-old foal and two extinct cubs near the ice wolf. In March last year, scientists found the remains of birds 46,000 years ago in the permafrost in northeastern Siberia, and in August of the same year, the remains of the Ice Age species "hairy rhinoceros" were found in the permafrost.
Some time ago, foreign media reported that the remains of bears that burrowed10.5 million years ago were found on the islands in the Arctic Circle. Judging from the investigation of the wreckage, it should have been frozen by the frozen soil, and then it was seen after the frozen soil melted. On the one hand, scientists can reveal the biological conditions of the Arctic tens of thousands of years ago by studying these ancient creatures. But on the other hand, the appearance of these ancient creatures is also warning mankind that there has been obvious melting of ice sheets and frozen soil in the Arctic.
If the greenhouse effect problem is not improved, where is the way out for mankind?
If the Arctic climate completely enters a new climate model in the future, it will have a great impact on the global climate environment. First of all, the methane released from the Arctic will further aggravate the deterioration of the greenhouse effect and make the climate problem more difficult. Secondly, the melting of Arctic sea ice will lead to global sea level rise, which will not only push Arctic creatures to the brink of extinction, but also seriously threaten the survival of creatures in other parts of the earth.
Scientists at the National Center for Atmospheric Research believe that once the Arctic climate completely enters a new model, human beings will be passively unable to cope with climate warming. In this case, human beings have been unable to stop the influence of the greenhouse effect. What is more serious is that human beings have no future on the earth. Of course, there are still hundreds of years before this possibility happens, so some people think that human beings can take this time to develop interstellar immigration projects.
According to Musk's grand vision, humans will land on Mars in 2030. With the rapid development of commercial aerospace, the follow-up trip to Mars will gradually become popular. By 2050, humans should be able to build the first livable city on Mars. There are still 29 years from Musk's dream of a Mars city. I wonder if his dream will come true then. In contrast, China's goal of building a modern country in 2050 is more likely to be realized.
Far water can't put out a near fire, and human beings have to face the reality.
In fact, apart from SPACE X, it is difficult for other space companies to have the strength to immigrate to Mars, because this project is not only to transport humans to Mars, but also to build a livable city on Mars. It is more difficult for human beings to transform Mars than to ascend to heaven at this stage. NASA, which has the highest level of aerospace science and technology in the world, is not sure to build Mars City in 2050, let alone other newly developed commercial aerospace companies.
So what is the difficulty in building a Martian city? First of all, humans need to establish a safe and stable protected area on the surface of Mars, because Mars has no magnetic field, only a thin atmosphere, the surface temperature is very low, and what is even more terrible is the cosmic radiation outside the chart. So how to build a protective cover that plays an atmospheric role? At present, no scientists have put forward reliable ideas or effective construction plans. Secondly, it is also a big problem for humans to transport materials to Mars.
Mars is not the closest planet to the earth. Even in the recent time, the distance between them is close to 55 million kilometers. However, the construction of Mars cities needs sufficient material support. If you can't use local materials, you can only transport them completely from the earth, which will be a huge expense, equivalent to the funds of several manned landing projects on Mars. There are many problems in transforming the Martian environment. Some problems may be solved in more than ten years, and some problems will be difficult to solve in another hundred years.
It can be seen that the desire of human beings to immigrate to Mars in the future 100 is not bright. We might as well face up to the actual situation of the earth, start making plans and take measures to improve the natural environment and climate of the earth. Scientists are more confident in improving the earth's environment than in transforming Mars. After all, human beings were born and raised in Sri Lanka, and naturally they will give us the greatest support.
Global warming is a fact, and Hawking's prediction has reference significance. Therefore, Hawking called on powerful countries to unite, face the common challenges of mankind hand in hand, continue to explore the universe and find the next planet suitable for human habitation in the next 200 to 500 years.
The one that won the Hugo Award was well received by readers and the media as soon as it was published. It is regarded as a milestone in China's sci-fi literature, attracting and bringing up countless sci-fi fans, and pushing China's sci-fi to the height of the world. And the author Liu has also become a god-like existence in China's science fiction world.
Liu: We must pay attention to these problems on the earth.
With the rapid development of human industry, in recent years, we have discharged a lot of carbon dioxide into the atmosphere, and the earth has begun to have a greenhouse effect.
In fact, in recent years, people's awareness of environmental protection has gradually increased, and environmental protection has become a topic. Liu Ye, a famous science fiction writer in China and the author of the science fiction novel Three-body, warned that we must be alert to the environmental problems on the earth.
In the novel Three-body, the three-body planet is no longer suitable for life. In order to continue their civilization, Sandy decided to move to the universe. Knowing the coordinates of the earth, they wanted to invade and were finally threatened by the "dark forest law" Their fleet had to change course, "wander" in the vast universe, and finally exposed the place, so they ran away.
Although "Three-body" is only a novel, its influence on us can never be compared with that of science fiction movies. Liu won the Hugo Award of the 73rd World Science Fiction Convention Novel Award for his Three-body novel, and won the first prize in Asia.
Now "Three-body" has been translated into 10 languages, with global sales exceeding 210 million, and Liu fans are all over the world.
There are three books in Three-body, namely: Three-body I-The Past of the Earth, Three-body II-The Dark Forest and Three-body III-Death Forever, each of which is extremely wonderful.
Cameron and Obama, FaceBook President Zuckerberg, Xiaomi, 360 Weeks and Tencent Ma are also admirers of "Three-body".
As soon as I contacted Three-body, I was immediately attracted by the compact script and the author's imagination. The "dark forest law" and "reducing dimensional blow" in the book completely monopolize my understanding of the universe and the world.
Liu has brought readers into a brand-new world, a magnificent world that China's writing has never created. In the cosmic black hole, the earth is like an ant, insignificant and precarious. No wonder Obama also lamented that after reading this book, he felt that being president was nothing!
"Three-body" will bring you the shock of reading and thinking. Will enlighten your values and outlook on life.
If you can't drink two cups of coffee, you can experience the most intimate masterpiece in the world.
