The highest surface temperature in Henan is 74℃, and trees in Nanjing are burned and cut off. Why is it so abnormal?

Since June, I have to say that only two words-"fire and heat" can describe this extraordinary summer! Because of the eruption of Tonga volcano, many people are worried about whether it will lead to a repeat of the "year without summer", but never imagined that this is completely a white worry. Although the summer of 2022 came a little late, it was "one second into the summer", which caused many "high temperature" and "abnormal" phenomena in China and even the whole world.

It makes sense that the equator is hot and humid all year round, but the summer in 2022 is very abnormal, especially for the northern hemisphere. Many parts of the world, including the United States, Chicago, French, Indian and even China, have experienced a persistent rare heat wave after a "burn out" and a "high fever". The earth is an organic whole, and any extreme phenomenon will inevitably lead to greater disasters. No, the phenomenon of spontaneous combustion of trees occurred in a section of Nanjing recently, which triggered a heated discussion. Is it natural or artificial? How to alleviate global climate anomalies?

Roadside trees in Nanjing, Jiangsu Province rarely burn their roots! Is it natural or artificial? It is reported that this happened recently. Located in Nanjing, Jiangsu Province, a very rare tree "spontaneously ignited" and burned its roots because of the hot weather. This is a very common tree that grows on the roadside. Unexpectedly, businesses doing business on the roadside unexpectedly found that it was actually smoking. In order to put out the smoke in the first time, I used a water pipe to put out the smoke, but I didn't expect the water pipe to put out nearly 1 hour.

So I asked the fireman for help, and the fireman went all the way to the heart of the tree to put out the fire. Maybe it's because I can't bear the load, and I'm worried that my back will collapse and hurt people. Finally, I called the garden department to cut down the tree and take it away. But many people have questions. On the one hand, they don't believe that it will be so hot, on the other hand, they don't believe that trees will spontaneously ignite. So I think it may be caused by throwing cigarette butts or sparks. So is it natural or man-made?

First of all, it needs to be clear that this spontaneous combustion of trees really happens naturally. The reason for this is that the Rubik's Cube seems to have the following points: First, if it is man-made, the fire will be outside, so when the merchants put out the smoke themselves with water pipes, they should put it out, not pour it out. Secondly, the reason why it must be considered spontaneous combustion is because the way to put out the fire after the firemen come is to dig out the heart of the tree. When the fire in the tree core went out, it really went out, indicating that the fire source was in the tree core.

Third, from the scientific principle of spontaneous combustion of trees, it is not completely impossible as netizens said, and it must rely on very high temperature to happen. First, it may be that the trees are hollow during the aging process, and many dead leaves and rotten leaves gather in the tree holes, forming a flammable environmental foundation. Biogas produced by long-term accumulation and fermentation is more likely to become the best ignition bait.

Finally, on the other hand, the weather in Nanjing is really not low. Judging from the photos and video clips taken at the scene, this tree is really an old tree. So, on the whole, this incident can really be treated as a natural event, and there is no need to make a fuss.

How hot is it in the summer of 2022? What is the "culprit" of rare heat waves in many parts of the world? I once heard a joke that an African brother arrived in China, but he was accidentally fainted by the sun and suffered from heatstroke. Many people will think that there are many funny ingredients in it at first, and they don't understand why Africa is hotter. But in fact, every summer is hot, and there is no national distinction. The heat has been distributed to different countries and regions. Henan has become an accessible place in the south, with the highest surface temperature exceeding 74℃. Isn't this an example of this truth?

After four days of high temperature weather, the highest surface temperature in Henan recently reached 74. 1℃.

How hot is the summer in 2022? Let's take a look at the rare high temperature in the world and its "abnormal" phenomenon!

1. Japanese experts have long said that the eruption of Mount Fuji is not unusual. Last year, a report even pointed out that the crater of Mount Fuji increased nearly six times. At present, in view of the latest detection situation, Mount Fuji may erupt, and the Japanese police agency has begun to make comprehensive preparations.

Because of the high temperature in the United States, the "fire" seems to have never been extinguished since last summer. Recently, due to the high temperature and heat wave, the highest temperature was as high as 42℃, which led to something that would not happen in 10 and 20 years: the cattle suddenly had a stress reaction, and at least 2000 cows were killed by heat.

3. Rare heat waves occurred in many parts of the world, including the United States and Chicago, and 70 provinces in France issued high temperature warnings. The highest temperature in India reaches 50℃. According to preliminary statistics, nearly 100 people have died due to extreme high temperature weather, which not only affects the local crop harvest, but also aggravates the risk of forest fires and power outages.

All the above events are caused by high temperature, but the impact behind them is far simpler than it seems. First of all, the biggest challenge of extreme high temperature to the world is people's production and life. Power failure, oil consumption, work, crop production, etc. Will be limited, and for countries and regions that are already short of water, the extra fires and water cuts that high temperature may bring are more terrible than one, and the consequences are unimaginable.

And the reason, scientists have given the answer-global warming! The latest assessment of IPCC has pointed out that the world must take measures to deal with climate change before 2030, so as to prevent the earth from reaching the critical threshold of 1.5℃ higher than the pre-industrial level and from breaking the critical point of climate.

In a quantitative research report on the impact of global warming on extreme weather events, experts pointed out that global climate change has increased the possibility of severe heat waves sweeping India and Pakistan in March and April by 30 times. But in fact, before man-made climate change, the probability of extreme high temperature weather in South Asia this year was once in 3000 years, but now it has been shortened to once in 100 years. And according to the forecast, if the average temperature of the earth rises by 0.8℃, such a heat wave will become once every five years.

But from the analysis of scientists, we can know that the root of all this may still be human behavior, so the "culprit" also points to human beings. Human society has been developing forward, with advantages and disadvantages. What we can do now is to try our best to control and actively improve.

The desert becomes an oasis! Global Warming China is on the move. As we all know, there is an enemy of global warming, that is, green forests, such as the Mu Us Desert in China, which is a model of global desert greening. From 65438 to 0959, with the Mu Us desert getting bigger and bigger, New China decided to formally start the desert reconstruction project. According to statistics, in order to change it, more than 380 women contributed their blood and hard work to this desert. Some have planted more than 2 million trees by themselves for more than 30 years, and some have accumulated more than 6.5438+million debts by planting trees.

Finally, through unremitting efforts, its greening has now changed from 0.9% to 42.9%, and 75% has become an oasis after decades of painstaking cultivation. As of April 2020, Shaanxi Forestry Bureau announced that the desertification control rate in Yulin has reached 93.24%, which means that the Mu Us Desert will soon "disappear" from Shaanxi territory and become the first "disappeared" desert in China and even the world.

The desert becomes an oasis, and China doesn't stop there! The original theory and complete set of technology of "desertification" developed by the team of Professor Yi Zhijian from Chongqing Jiaotong University have been industrialized this year under different desert conditions, such as Wulanbuhe Desert in Inner Mongolia, Taklimakan Desert in Xinjiang and Zoige Grassland in Sichuan, after five years of large-scale experiments of 6,543,800+0.7 million mu.
