Is it normal for the Arctic Circle to measure a high temperature of 38°C?

According to the "Russia Today" TV station, on June 20 local time, the Russian Siberian town of Vrhoyansk located in the Arctic Circle measured a high temperature of 38 degrees Celsius, breaking the highest temperature record in the Arctic Circle since the record.
As soon as the news came out, people were distraught. Was the kind of flooded end of the world scene depicted in the disaster movie "2012" coming?
Local high temperature and abnormal
Dai Yunwei, a senior engineer at the Central Meteorological Observatory of the China Meteorological Administration, responded unequivocally: "The high temperature recorded at 38 degrees Celsius in Verhoyansk is only incidental and is not normal. And because it is not normal, the ecology of the Arctic region will not change suddenly. This is the global climate. Local extreme weather phenomenon against the background of warming."
In other words, climate change is a human issue and an international issue, and its participants can only be national and international organizations.
Global warming has become a topic of daily discussion among the people after decades of heated discussion in the media. But climate change is actually a multi-dimensional, long-term, and large-space super-macro issue, which is not directly related to a certain region or even some countries.
Mankind has generally recognized the globality, importance, and severity of climate problems, but if we want to solve climate problems and their resulting local high temperatures, extreme disasters, and even ecological crises in a short time, low dimension, and small scale, we can only be wishful thinking.
High latitudes are more sensitive to climate change
The town of Vrhoyansk is about 4,700 kilometers northeast of Moscow. There are about 1300 residents here, and it takes about 2 days to transfer from Moscow to the local area. What does the high temperature of 38℃ measured in such a sparsely populated town really mean?
Dai Yunwei believes that this should be combined with history and reality.
He explained: From a historical point of view, the Guinness Book of World Records once certified that the most extreme temperature difference has occurred in the town of Vrhoyansk. The lowest local temperature has been measured as an extreme low temperature of minus 68 degrees Celsius, but the highest temperature is also 37 degrees Celsius, and the relative temperature difference is 105. ℃. In this way, it seems that the maximum temperature from 37 ℃ to 38 ℃ is no big deal; conversely, if the low temperature of minus 69 ℃ is measured again this winter, it does not mean a qualitative change. "Because this 38°C is just an occasional phenomenon, it does not have linear deduction and normal nature. It is safe to say that there is little possibility of progressive evolution of 38°C this year, 39°C next year, and 41°C the following year."
Dai Yunwei also emphasized that under the general trend of global warming, sensitive areas such as high latitudes are significantly affected more than low latitudes. The town of Vrhoyansk, located in the Arctic Circle, is a typical example of the impact.
Urgent need for more comprehensive monitoring and research
Although the local temperature will not rise year after year, other countries in the Arctic Circle have also measured historical extreme high temperatures in recent years. The Arctic area has a lot of sea ice melting, the permafrost is melting, and the frequency of forest fires has increased. These far-reaching effects of natural phenomena on human beings are currently under precise monitoring and research.
Compared with astronomical units calculated in light years, climate change must at least comprehensively compare data over a million years. Dai Yunwei made a vivid analogy: "For example, the security of a certain area has deteriorated, we can only expect that a large number of robberies will occur in this area, but we cannot accurately predict the time and date of a certain year, month, and day, and at a specific address. Was robbed."
The “police” of the Earth’s climate balance is now worsened by “climate warming”, “then at what time and the consequences of this kind of disaster will bring disasters to which countries and regions, it is still an urgent research topic. ."
Dai Yunwei believes that the earth, like the human body, has its own small cycle and a large cycle between the universe, generally following certain rules, and there are also changes in solar energy and cloudy weather at four o'clock. "Considering the global cycle of climate change, the currently established scientific prediction model still needs time to test."
It should be pointed out that not all climate change brings bad things.
For example, the melting of Arctic sea ice has certain appeal to the development of Arctic waterways, and the open development of permafrost regions in Russia, the United States, Canada and other Arctic Circle countries has also been on the agenda.
Dai Yunwei added, "Of course, the development of the Arctic region is also a new issue. It needs the attention and wisdom of the world, including Arctic and near-Arctic countries, to play chess first and to minimize the negative effects."
To adapt to climate change, but can’t wait to die
In the face of global climate change, we can no longer sit still and human beings should take measures to adapt and slow down their changes.
Dai Yunwei gives a few suggestions——
First, we must adapt to the impact of climate change on water resources. With the abnormal change of climate, the uneven distribution of water resources in time and space is further exacerbated, the efficiency of water resources utilization is reduced, and the cost of water resources utilization is rising. Moreover, the problems of floods, droughts and deterioration of the water environment will also become more serious with global warming. Therefore, it is necessary to formulate countermeasures to adapt to the impact of climate change on water resources as soon as possible.
Second, we must adapt to the impact of climate change on the coastal zone. The rise in sea level caused by global warming has severely affected coastal ecosystems, biological resources and coastal environment, and it will also increase flood disasters.
In the face of global warming, all countries and regions in the world need to participate together to continuously strengthen the monitoring and early warning of sea level rise. Build protective engineering facilities such as dams and embankments, and formulate ecological system protection measures. Develop sustainable strategies suitable for global development.
Finally, we must pay attention to the impact of the Earth's tripolar changes. The Arctic, Antarctic, and the Tibetan Plateau in China are all regions with relatively fragile ecological environments that are susceptible to climate change, and changes in these three poles will in turn affect the entire ecological cycle of the planet. The earth does not need human salvation. All human efforts are just to save humanity and seek an environmentally friendly, ecological and sustainable development path for itself.
In the end, Dai Yunwei believed, "The news that Verhoyansk recorded a high temperature of 38 degrees Celsius is very good, which reminds all mankind: pay attention to ecology, protect the environment, and care about climate change. After all, humans have only one earth!"
