What causes ultra high temperatures in summer? Why do people still die of heat in the summer?

Especially in the north now, it is rare to see dozens of degrees below zero in winter, when the down jacket was still worn more than ten years ago, and now the north in April has been replaced with short sleeves, the main reason behind this is because in recent years human beings have wantonly destroyed nature, resulting in a series of chain reactions of the greenhouse effect, human industrial development has polluted the earth's natural environment, although our human civilization continues to progress, but in the process of progress has also caused us great drawbacks.

However, the greenhouse effect only appeared in the last century, and since the Industrial Revolution, it has only been more than 200 years old, but such a strange thing happened in ancient times, a summer was unusually hot, according to the records at that time, the temperature in North China at that time, the summer directly reached 44 degrees Celsius, and more than 10,000 people lost their lives in this summer, what is the reason behind this?

Now the summer is hot, we can eat ice watermelon, turn on the air conditioner, blow the fan, etc., and in ancient times, people can only use fans to relieve the heat, July 1943 should be the hottest summer in Chinese history, when the weather is much hotter than in previous years, summer comes earlier than before, many rivers and lakes are close to drying up because of the high temperature, for some rich and noble families can spend money to buy water, some poor people can only suffer silently, and even lost their lives.

Many people are curious about why the greenhouse effect only appeared in the last century, so why there was such a high temperature in 1943. Scientists speculate that perhaps because of the circulation in the middle and high latitudes of the European continent, North China is just in the low pressure trough and the air pressure can not flow, can only be under the high temperature, and finally there is extreme weather, but in 1999 there was a similar situation, the temperature in North China directly reached 42 degrees Celsius, so that many people complained.

We can eat watermelon in an air-conditioned room when it's hot, but for some ancient people, they will also dress tightly in summer, and they will not wear cool like modern people, for some rich people, how do they face the heat? Although there were no refrigerators in ancient times, the wisdom of the ancients was also powerful, and they invented the unplugged refrigerator for storing ice.

Although today's cooling tools are relatively complete, we cannot give up our vigilance, after all, the greenhouse effect has brought us more trouble, if we do not refrain from continuing to wantonly destroy the earth, perhaps only human beings themselves will be harmed.

There are many reasons for the high summer temperatures, such as industrial emissions and carbon dioxide, which can also contribute to global warming. Because some people have poor physique, they will die of heat when the temperature is too high.

It is mainly because of human greed and wanton destruction of nature for profit, resulting in a series of reactions caused by the greenhouse effect, which will make the earth warm and the summer hotter and hotter. Nowadays, people have air conditioners to blow fans and eat cold food, but in history, people wore too much and could not use effective methods from the outside world to cool down, so they would have high body temperature and even die of heat stroke.

Drought and lack of rain, slow atmospheric flow, and heat emitted by human industry all contribute to extremely high summer temperatures. Because the temperature is too high, some people with poor physique will not be able to withstand it, resulting in heat death.

The heat event has affected more than 900 million people in our country, covering an area of up to 10,000 square kilometers. "High temperature" has become a hot topic from June to the present. In my personal opinion, the climate is complex and changeable, and the hot summer this year does not mean that it will be so hot every year in the future, and it will tend to get hotter and hotter.

We live on the same earth, the climate and environment will affect each other, and we also belong to the "grasshopper" on a rope. Global warming will affect all human beings, and no one will be immune. As for whether the summer will get hotter and hotter in the future, I personally have an objection because of the following two reasons.

The Earth is vast and has an area of 3 4 waters. It is precisely because of such a unique structure that the earth's climate is complex and changeable, and the hot and cold climate may not be staged every year.

This year's hot summer has been mainly affected by the ongoing La Niña event. This is not the case every year, with some summers being hot and some being cool. Just because it's hot one year doesn't mean that the temperature will be like this every summer.

In addition to the global climate change, all countries in the world are also actively paying attention to climate and environmental changes. The early warning and extraordinary signals issued by Mother Earth have attracted people's attention and attention, and in order to prevent the climate and environment from continuing to deteriorate, many countries have worked together to start protecting the climate and environment.

I believe that with the joint efforts of the people of the world, the deterioration of the climate and environment will be alleviated. Although it is difficult to restore the climate to the situation of hundreds of years ago in a short period of time, it can stop the deterioration and allow the climate and environment to recover little by little.

In response to high temperature weather, we must pay attention to the weather forecast in time, and at the same time pay attention to heatstroke prevention and cooling, and put physical health and life safety in the first place.

Yes. The high temperature event has affected more than 900 million people in China, and this summer is very sad, the hot weather covers a wide range of areas, and the duration is also very long. According to the data, since June 2022, the average number of high temperature days in China has been as long as days, which is more than in the past.

**The Meteorological Observatory has issued many orange warnings for high temperatures, and many regions in China have long duration, wide range of influence, and strong extreme high temperature weather, and even the temperature in some areas of Hebei has been as high as 44, which is a very rare temperature.

Later summers will get hotter and hotter, because as the greenhouse effect becomes more and more severe, the later summers will get hotter and hotter.

In the future, it will get hotter and hotter every summer, and now there are more and more greenhouse gases, which is the reason for this.

In fact, there are three reasons for this situation, one is that extreme weather is relatively common, which may be related to global warming. Second, the subtropical high has not disappeared, and an unusually strong warm high has formed over the Northwest Plateau, which may be integrated with the subtropical high. Third, there have been major changes in ecosystems, such as rising greenhouse gas concentrations and rising sea levels.

Experts** Summer temperatures are likely to rise continuously, with extreme weather like this occurring every 5 years.

The ultra-hot weather in the summer of 2022 has continued, which has affected people's lives a lot and people have complained about birth. In fact, it is very normal to have high temperature weather in summer, but this year's high temperature weather is very strong and lasts for a long time, which is more extreme. Pee also explained some reasons above, which is also the response of experts, we can also take a look at the weather forecast, and we will find that the rainy days are relatively rare, even if there is no sun, the cloudy days are particularly stuffy, making people feel like they are in a steamer.

In addition, under the influence of the continental high pressure and the warm high pressure of the northwest plateau, the high temperature weather may last for a long time. And it's much hotter in the city than in the countryside, because the exhaust fumes from the cars also raise the temperature around them.

Experts also ** hot weather may further expand, for example, most parts of the south will have persistent high temperatures, and parts of the northwest and southwest will also have the highest temperatures, which may break through historical extremes. This wave of weather may last for 10 days or more, in fact, now the weather forecast can already see the weather within 15 days, and people will find that the temperature after that is above 37 degrees, and even 40 degrees Celsius. People are moving to cities all the time, and there are more and more high-rise buildings, and the heat island effect is also very strong, so the temperature will become higher and higher.

High temperature weather will have some extreme effects on the human body, so it is still necessary to turn on the air conditioner when it is particularly hot.

It may be because the influence of the Arctic has affected our Central Plains, and I think it will continue, mainly because the current environment is still unstable.

Because since this year, our carbon dioxide content has been out of control, and now the greenhouse effect is more serious, if we do not protect the environment well in the future, it will continue**.

It is because this year's production environment has been damaged to a certain extent, and the cold air is far away from our life circle, so it will be **, I think it will be ** in the future.

<> because the earth has been closed around the sun, when it turns to the northern hemisphere, it will be directly exposed to the sun, resulting in the phenomenon of continuous high temperature in summer, and secondly, because of the high energy consumption now, resulting in global warming, so in the summer, it will cause the situation that it gets hotter and hotter every year.

The reason why the high temperature is so hot is global warming.

Global warming: Although there have been periodic changes in the global climate due to high temperatures and droughts this year, local special weather systems such as tropical high-pressure climates, and the heat island effect, the main reason is global warming. According to the World Meteorological Organization, the global high temperature phenomenon that occurred this summer is the result of global climate change.

In the context of a global warming climate, extreme heat is expected to become more frequent and intense in the future, and if greenhouse gas emissions continue to increase, the greenhouse effect will increase even more dramatically.

The reasons for this rare high temperature can be summarized in three points:

First of all, the rainy season in the middle and lower reaches of the Yangtze River is shorter than in previous years, and the plum season is early, and the subtropical high has continued to control the middle and lower reaches of the Yangtze River since the beginning of July.

Secondly, the intensity of the subtropical high is significantly stronger than that of the same period in history. In previous years, the middle and lower reaches of the Yangtze River were still in the rainy season in early to mid-July, but this year, due to the early emergence of the plum season, the number of high temperature days is obviously more, and the subtropical high pressure is relatively strong, resulting in the temperature continuing to rise.

Third, there is the anomaly of atmospheric circulation, and so far there are few typhoons that have moved north and deep inland. In previous years, because of the landfall of typhoons, the subtropical high will retreat and break under the influence of typhoons, and the weather will also show a hot burst, and a typhoon will come and cool down, which is called intermittent high temperature.

This year, the typhoon has a southerly impact, mainly in the Taiwan Strait and the South China Sea, causing the subtropical high to control the inland for a long time, so it is reasonable that the high temperature will suffer the middle and lower reaches of the Yangtze River for a long time.

Because the solar altitude angle moves to the Tropic of Cancer after the summer solstice, the days are long and the nights are short, resulting in high temperature and rain, strong atmospheric inverse radiation, and good thermal insulation effect, so it is hot both day and night in summer. The three dog days, which are the collective name for the first, middle and last volts, are the hottest times of the year. "Fu" means that the yin energy is forced by the yang energy to hide in the ground of the land skin.

The dog days occur from mid-July to mid-August of the Gregorian calendar, and their climate is characterized by high temperature, low air pressure, high humidity, and low wind speed. The so-called "heat in the three dogs", the three dogs are divided into the beginning, the middle and the end, and its date is determined by the date of the solar term and the date of the dry branch.

China's traditional calculation method stipulates that the third Geng day after the summer solstice is the beginning of the first volcane, the fourth Geng day is the beginning of the middle volcane, and the first Geng day after the beginning of autumn is the beginning of the last volcane. Because there are 10 days between each Geng day, the prescribed time for the first and last days is 10 days. The number of days in the middle of the volt is long or short, it may be 10 days, or it may be 20 days, depending on the date of the appearance of the third Geng day (the first volt) after the summer solstice every year.
