Since June, it must be said that only two words - "fire, hot" can describe this extraordinary summer! Because the eruption of the Tonga volcano began, many people are worried about whether it will lead to "no summer year" repeat, but never thought this is completely white worry. 2022 summer although a little late, but is "a second into the summer", and in our country and even the world! The company's website has been updated with the latest information on the company's website, which is available on the website.

The equator is hot and humid all year round, but the summer of 2022, especially for the northern hemisphere, is very unusual. Many places around the world, including the United States, Chicago, France, India and even our country, one "burned out" and another "high fever", there is a continuous rare heat wave. Earth is an organic whole, any extreme phenomenon inevitably may lead to greater trouble. This is not, Nanjing recently a section of the trees on the spontaneous combustion phenomenon triggered heated debate, whether it is natural or man-made? Global climate anomaly and how to mitigate?

Jiangsu Nanjing roadside trees rare spontaneous combustion broken roots! In fact, natural or man-made?

It is reported that this incident occurred in recent days. The location is located in Nanjing, Jiangsu Province, because of the hot weather, the roadside occurred a very rare tree "spontaneous combustion" burned off the root of the incident. This is growing in the roadside very common trees, but did not expect the roadside businessmen but accidentally found it actually in the smoke. In order to extinguish the first time, so with a hose to extinguish the smoke, but did not expect the hose poured nearly 1 hour did not extinguish.

So turn to firefighters, firefighters have been hollowed out to the heart of the tree position to put out the fire. Perhaps because it is indeed load-bearing can not, worried about the back of the collapse injury, so finally called the gardening department will be cut down the tree to take away. But many people have doubts, on the one hand, do not believe that it will be so hot, on the other hand, do not believe that the trees will spontaneously combust. So think it may be man-made littering cigarette butts, or threw what sparks to cause. So is it natural or man-made?

First of all, we need to make it clear that the spontaneous combustion of trees is indeed a natural occurrence. The reason why the magic formula seems to have the following main points: First, if it is man-made, then the fire point will be outside, so when the merchants themselves with a hose to extinguish the smoke should be extinguished, rather than the more poured the bigger and bigger, but also can not be extinguished. Secondly, there is another reason why the fire was definitely thought to be spontaneous combustion, and that is because the firefighters came and extinguished the fire by pulling out the heart of the tree. When the fire in the heart of the tree was put out it was really put out, indicating that it was the inside of the heart of the tree that was the source of the fire.

Third, from the scientific principle of spontaneous combustion of trees, is not as netizens say is completely impossible, must rely on very high temperatures to happen. For one thing, it may be that the tree aging process formed a hollow, and the tree holes gathered many dead and decaying leaves, forming the basis of a flammable environment, a long time of accumulation and fermentation of methane gas is more likely to become the best ignition bait.

Finally, on the contrary, the weather in Nanjing, indeed not low ah. From the photos taken at the scene as well as video footage, the tree is also really old. So all in all, this incident can indeed be viewed as a naturally occurring event, and there's no need to make too much of a fuss about it.

How hot will the summer of 2022 be? Many parts of the world with a rare heat wave "culprit" is what

Have heard a paragraph, an African brother to China but accidentally sunstroke, but also heat stroke. Many people will start to think that this is a funny component of the majority, do not understand obviously Africa will be hotter why it will be so. But in fact, every summer high temperature, there has long been no distinction between countries. Hot has no country and region, Henan become "can" South, the surface of the hottest temperature is also more than 74 ℃, is not an example of this truth?

The hot weather lasted four days, Henan recently reached a maximum surface temperature of 74.1 ℃.

How hot is the summer of 2022? Let's take a look at the rare global high temperatures and the resulting "anomalies"!

1. Japanese experts have long said that it's not unusual for Mount Fuji to erupt. A report last year even pointed out that Mount Fuji's crater increased nearly six times, and now, in view of the latest detection of Mount Fuji or eruption, the Japanese police department has begun to make comprehensive preparations.

2. The U.S. has been experiencing high temperatures since last summer, and the "fires" don't seem to be going out. And recently because of the ushered in a heat wave, the highest temperature up to 42 ° C led to the emergence of 10 years, 20 years are unlikely to happen: cattle suddenly stress reaction, at least 2,000 head of cattle were heat death.

3. The United States, Chicago, including many parts of the world, a rare heat wave, the whole of France is 70 provinces issued a heat alert. India's high temperatures reached 50 degrees Celsius, preliminary statistics have nearly 100 people died due to extreme heat, affecting the local crop harvest at the same time, but also exacerbated the risk of forest fires and power outages.

These incidents are all due to high temperatures, but there's more to it than meets the eye. First of all, the first major challenge that extreme heat poses globally is people's productive lives. Power outages, oil, work, crop production and so on will be limited, and for countries and regions that are already short of water, the heat may additionally cause fires, disconnections, water cuts, one more than one terrible, the consequences are unimaginable.

And the reason, scientists have long given the answer - global warming! The latest assessment by the Intergovernmental Panel on Climate, IPCC, has already pointed out that the world must make moves to combat climate change by 2030 if the planet is to avoid reaching a critical threshold of 1.5 degrees Celsius above pre-industrial levels, preventing a breach of the climate tipping point.

In a report quantifying the impact of global warming on extreme weather events, experts said global climate change has made it 30 times more likely that a severe heat wave will sweep through India and Pakistan in March and April. But the fact is that before human-caused climate change, the probability of an extreme heat wave in South Asia, like this year's, was once every 3,000 years, but that has now been reduced to once every 100 years. And as predicted, if the Earth's average temperature rises by another 0.8 degrees Celsius, such heat waves will become once every five years.

But scientists' analysis shows that the root cause of all this may still be human behavior, so the "culprits" are also pointing to humans. Human society has been moving forward, there are advantages and disadvantages, and all we can do now is to try to control and improve.

Desert to oasis! Global warming China in action

It is well known that global warming has a major enemy, that is, green forests, such as the global desert greening model - China's Mao Wusu Desert. In 1959, with the Mao Wusu Desert getting bigger and bigger, New China decided to officially launch the project of transforming the desert. According to statistics, in order to change it, *** more than 380 women contributed their blood and hard work to this desert. Some of them planted more than 2 million trees in 30 years by their own strength, and some of them went into debt for planting as much as 10 million dollars.

Finally, after unremitting efforts, it is now green from 0.9%-42.9%, after decades of painstaking cultivation has been 75% into an oasis. As of April 2020, Shaanxi Forestry Bureau announced Yulin sandy land management rate has reached 93.24%, which means that the Mao Wusu Desert will soon be "disappeared" from the map of Shaanxi, China and the world's first "disappeared" desert.

The desert into an oasis in China is not the only thing! Chongqing Jiaotong University, Professor Yi Zhijian team research and development of "desert soil" original theory and complete sets of technology after five years, in Inner Mongolia Ulanbuh Desert, Xinjiang Taklamakan Desert, Sichuan Ruoergai grasslands and other different desert conditions up to 17,000 acres of large-scale testing, this year officially began industrialization and promotion.
