There was a high temperature of nearly 47℃ in the middle of this year. Is it because of the greenhouse effect? Is this about the car?

I believe many people have this feeling. This summer is hotter than usual. Obviously, summer comes late, but in August, it is more difficult than any other summer. It is reported that in August and September, there will be a high temperature of 47 degrees in some parts of the world. Why is it so hot this summer?

Some people speculate that the greenhouse effect has reached its peak, so the earth will be as hot as a fireball, which is part of the reason, but this summer's heat is caused by many factors and needs to be considered.

First, the mid-range has a high temperature of nearly 47°C, mainly in Africa.

According to news reports, some areas have reached a high temperature of 47 degrees. These places are mainly in Africa. On the East African Prairie in Africa, it is possible to form a high temperature of 47 degrees in August and September, which is the result predicted by experts. There will be no high temperature of 47 degrees in China.

47 degrees is the highest temperature in the history of grassland in East Africa, and there was an extreme high temperature of 47 degrees in 1990. Experts predict that due to the intensification of the greenhouse effect, the East African grassland will reproduce the extremely high temperature of 1990 this year.

Second, why is this year hotter than previous years? Reason: There are more vehicles in the city.

In China, why is it hotter this year than usual? Part of the reason is that there are more vehicles in the city, which will emit more exhaust gas and form the heat island effect. Urban heat island effect is a geographical term for climate warming. We can feel that the weather in the countryside is relatively cool, but in cities without air conditioning, it will be very uncomfortable and the temperature is very high. This is the heat island effect.

Third, why is this year hotter than previous years? Part of the reason is the greenhouse effect

Some netizens speculate that the reason for this year's heat is the greenhouse effect, but the greenhouse effect is only part of the reason for the earth's heat. In the past two years, there have been many holes in the ozone layer, and ultraviolet rays can reach the surface of the earth directly, so the surface temperature of the earth will be hotter than in the past two years. There are more and more direct ultraviolet rays on the earth, and the surface of the earth has no time to dissipate heat, which has caused the high temperature this year.

4. Why is this year hotter than previous years? Cause: The air pressure in the Pacific Ocean is low.

Our China is very hot this year, partly because we are close to the Pacific Ocean. Being close to the Pacific Ocean has both advantages and disadvantages. The advantage is that the water vapor in the Pacific Ocean can cool China, but there is also a disadvantage this year. The pressure in the Pacific Ocean is relatively low, which will cause the Pacific gas to float into the sky, float to China and deposit on the land of China.

When the local surface puts pressure on China's land, the air pressure will become higher, and China will be hotter, while the air pressure in the Pacific Ocean will become lower, so the transmission of water vapor will not easily spread to China's mainland, so China will be hotter this year.

5. Why is this year hotter than previous years? Reason: Antarctic ice is decreasing.

The reason for the hot weather this year is that the Antarctic ice is decreasing. Antarctic ice is formed all the year round, usually huge icebergs. Penguins can thrive on icebergs. Antarctic ice will also be transported to all parts of the world in summer, and water vapor can play a regulatory role.

In recent two years, the greenhouse effect has become more serious, and the Antarctic ice is melting. We can see the news that Antarctic icebergs often collapse from some news videos. This is that the Antarctic iceberg is gradually melting, and there is not as much ice as in the past.

6. Why is this year hotter than previous years? Reason: Artificial rainfall is cautious.

The reason why the weather is hot this year is that our government is more cautious about artificial rainfall. There was more artificial rainfall in the past two years, which cooled our hot weather. However, in the past two years, the policy given by the Meteorological Bureau specifically stated that artificial rainfall would be used cautiously. Artificial rainfall is a means to force the weather to change, and it will not be used unless it is absolutely necessary.

The best way for people to get along with nature is to conform to nature. If we use some technical means to change the weather, it will destroy the balance of nature. In the long run, we should conform to nature, not confront it.

Summary:

There are many reasons for the hot weather this year, which cannot be simply summarized by the greenhouse effect. Of course, it is not a good thing for the weather to get hot, and the greenhouse effect continues. Some netizens said on the Internet that the weather is getting hot and can be adjusted by artificial rainfall. The staff of China Meteorological Bureau also made a special explanation on the Internet. Abuse of artificial rainfall is not allowed, and the weather is hot. I suggest you protect yourself from heatstroke.
