There has been a rare high temperature in the Arctic for tens of thousands of years. What happened? Is the earth sick?

The year 2020 is already the 20th year for mankind to enter the 2 1 century, and the first 20 years of the last century is the greatest era since mankind entered the era of science and technology. Because at that time, a group of great scientists appeared and put forward great theories that have far-reaching influence on mankind, such as Einstein's theory of relativity.

In the first 20 years of last century, although mankind made great progress in science and technology, people talked more about the ecological environment. Especially in recent years, the deteriorating ecological environment has attracted more and more scientists' attention. In particular, 2020 is an extraordinary year, and the virus epidemic that has continued from the beginning of the year to the present has not stopped.

In addition, since July, China's southern time has ushered in a rainstorm test. I believe many friends know that in recent days, the rainfall in the middle and lower reaches of the Yangtze River in China has generally reached 400-000 mm, and the local area has exceeded 1 0,000 mm. Many netizens have complained that this year is simply a storm nest, and the rainstorm has been nonstop.

Under the violent attack of heavy rain, the water level in many areas in the south has risen sharply, reaching a dangerous warning line. Some landscapes and some ancient buildings along the coast in many places were flooded. The reason why there is such a violent rainstorm is actually due to the continuous deterioration of the earth's ecological environment, especially the rise of global temperature, which has a huge impact.

Speaking of global temperature rise, 2020 will refresh people's cognition again and again. I believe many friends know that there are two coldest places on the earth, the South Pole and the North Pole, which represent the most extreme cold climate areas on the earth. If there is high temperature in other places, such as China, where the temperature is above 38 degrees Celsius, it is very normal in the current global warming background.

But what would you think if this high temperature climate appeared in the north and south poles? Many people may say, how is this possible? If the temperature in the polar regions can reach 38 degrees Celsius, won't the earth be finished? Although we didn't want this to happen, the real situation happened, which happened last month.

If you pay attention to the global climate, I believe everyone knows that there was a terrible high temperature weather in the Arctic Circle in late June that was rare for tens of thousands of years. The weather station located at 73 degrees north latitude along the Arctic Ocean in Russia, the temperature rose to 34.3 degrees on June 30th, setting a new record for the highest temperature along the Arctic Ocean, which was more than 25 degrees warmer than normal! Around June 20, an amazing high temperature of 38 degrees occurred in Yersk, East Siberia, which is also located in the Arctic Circle, breaking the local historical record.

I believe everyone is familiar with East Siberia, which is one of the coldest places in the northern hemisphere. I believe many friends often hear this in the central weather forecast: most parts of China will cool down due to the influence of Siberian cold air. It can be seen that the cold air in Siberia is very strong, which also shows that it is a very cold place.

In such a cold place, a rare high temperature of 38 degrees Celsius appeared in June 2020. Do you feel horrible? Indeed, the appearance of such high temperature in Siberia makes scientists feel incredible. Scientists also know that under the background of global warming, the Arctic region is one of the fastest warming regions in the world at present, but they did not expect that its warming speed would be so fast.

Although this hot weather in Siberia will not last, an important message it sends to mankind is that we are very worried. There was a brief high temperature of 38 degrees Celsius in Siberia this year, so it may happen again next year, or even last longer. If this continues, it will not be good news for the entire Arctic.

Many people may think that the rising temperature in the Arctic is a great influence of melting glaciers, but in fact, the rising temperature in the Arctic and melting glaciers are only a small influence. What really worries scientists is the comprehensive restoration of permafrost. Anyone who knows something about the Arctic should know that the Arctic has the largest permafrost in the world, and Siberia is in the permafrost area.

Permafrost is a very old frozen place on the earth, which may have existed for tens of millions of years. There are many things frozen in it, such as greenhouse gases such as methane and carbon dioxide. In May this year, due to climate change, the permafrost in Siberia melted, leading to the occurrence of greenhouse gas leakage. In recent years, the frequency of such incidents has become higher and higher.
