The Arctic has begun to accelerate warming, and the speed has increased by 4 times. Experts: worried about the release of "deadly germs"
Arctic warming begins to accelerate, 4 times faster, experts: worried about releasing "deadly germs"
Some time ago, Mika Rantanen, a meteorological researcher from Finland, It is found that in the context of global warming, the Arctic is facing a serious problem - in the past 40 years, the rate of warming in the Arctic has turned out to be four times the global average. In the past, scientists once believed that the rate of warming in the polar regions was only about twice the global average. Obviously, the new research results show that the problem is becoming more and more serious. The same problem will also appear in the Antarctic. For example, in March this year, extreme high temperatures occurred in both the North and South poles. According to the temperature data at that time, the Antarctic Concordia Station, which was located at an altitude of 3.4 kilometers, was on March 18. The temperature on this day was nearly 40 degrees Celsius higher than the same period in history. At the same time, the high temperature records in many places in the Arctic were also broken on the same day, which shows that many unusual things are happening in both the Antarctic and the Arctic, and this is not a good thing for human beings. information. What are the consequences of accelerating warming at the poles?
The direct impact of high temperature is the melting of glaciers and permafrost. Take the Arctic as an example. As early as last year, scientists found that the melting rate of Arctic sea ice has reached more than twice the rate of previous studies. It also shows that the melting rate of Arctic sea ice is far faster than human predictions. Perhaps starting from 2035, the Arctic summer will officially enter a state of "ice-free". The same is true for Antarctica. The study believes that it will only take thousands of years at most for the ice sheet of West Antarctica to disappear. What is the concept? Simply put, the global sea level will rise by at least 3 meters. At the same time, extreme weather on earth will become more and more normal. Of course, in addition to these visible and felt changes, in fact, in the thawing of the permafrost in the Arctic, there are still some invisible crises that are also approaching the human world, and they may bring about in the future. The impact is unpredictable, and it may make human civilization press the pause button without knowing when. Arctic warming could unleash 'deadly germs'
Scientists for the first time in Siberia's thawing permafrost late last century , found a well-preserved remains of a prehistoric creature, a mammoth, which has a history of tens of thousands of years. Although it has been a long time, it has been sealed by ice, which also makes its hair clearly visible. , looks as if he just died. Obviously, this discovery is good news for scientists, because they can no longer study prehistoric creatures through fossils, skeletal remains, etc., and can feel the appearance of prehistoric creatures more intuitively. However, as more and more biological remains are discovered in the permafrost, finally, some scientists realize that this may not be a good thing, because in addition to these visible prehistoric creatures, there may be some Missing prehistoric creatures - ancient microorganisms, various germs, bacteria. As early as a few years ago, scientists discovered the existence of ancient bacteria in the Arctic permafrost. Surprisingly, they can "wake up" again in the laboratory environment, although this shows that the life of microorganisms is It is very tenacious, but it also means that scientists' worries have come true. It is possible that many ancient germs have quietly flowed into nature unknowingly. This is not an alarmist. As early as 2019, some scientists pointed out that changes in the Arctic climate may release a large number of "deadly germs", and in Siberia in 2016, a reindeer died of "anthrax virus". The corpse reappeared in the world as the permafrost thawed, and the virus it carried also caused a large-scale infection of the surrounding residents and reindeer herds, which had a great impact at that time. And in recent years, the number of new germs discovered by scientists has indeed been increasing. On the one hand, it is indeed because of human scientific progress that scientists can better discover new microorganisms. On the other hand, it is also related to global warming. It is related to the melting of glaciers and permafrost, because this will make it easier for unknown germs to be exposed. For example, as early as the 1980s, a new virus appeared in the seal population of the Arctic. It spread very fast, and a large number of spotted seals died as a result. Later, through research, scientists found that this is actually related to The melting of Arctic glaciers is related, so no one can say whether the next new germs exposed will infect humans. Therefore, many researchers believe that in the future human world, there may still be a more serious "infectious disease crisis", and the source of this infectious bacteria may be related to the permafrost in the Arctic. It can be said that these invisible dangers are far more terrifying than the visible dangers, and they are also easier to "knock down" human beings. Therefore, finding ways to prevent the situation from worsening is the most important thing for human beings to do, friends. what do you say?
