Why is it getting hotter every year? Why the weather is getting hotter every year

Did you turn on the fan today?

Yes, it's getting hotter and hotter now, and this year Hangzhou has become a furnace, and in a few years, there will definitely be furnaces everywhere in China! It's getting so hot right now, it's related to global warming, it's also related to the rapid urbanization of our country, and now we don't see any green belts in the cities, and we don't have access to the "earth" everywhere

The summer of 2022 is really hot, and everyone is very uncomfortable with this hot weather. 2022 is so hot because of the hot weather.

There is an extreme phenomenon, not only in China, but also in many countries around the world have high temperature weather, extreme situations, if you want to make the temperature not so high, then we must protect the environment, to reduce carbon emissions.

The second reason why the weather becomes hot is the hot weather formed by the warm high pressure of the plateau, and the relevant expert table and socks show that in the western plateau of our country. In fact, a relatively strong warm high pressure has been formed, and the emergence of this warm high pressure is also very abnormal, so it has led to a significant rise in temperature in our country. Authorities said that such hot weather may last for another ten days, or half a month.

In addition, as long as the weather changes slightly, the heat will choose to use the air conditioner, which also has a great impact on the air and temperature. Many people who work outdoors have been complaining about the weather, which is so hot that there is no way to carry out the work.

I think that if there is no way to change the status quo of the earth, then the next year may be hotter than the next year, and now the temperature in many parts of our country has soared directly to more than 40 degrees, which is simply unimaginable. This kind of extreme weather.

In fact, the emergence of human beings has a very big relationship with human beings themselves, because we usually overexploit and destroy the ecological balance.

That's why this kind of extreme weather is happening.

Now our country has not yet entered the ambush, and it will be hotter after the ambush, and this year the ambush will last for a long time, about 40 days. The hot weather does affect everyone's life, and we have no way to change this kind of weather, and now when you enter the room, if there is no air conditioning, it is really uncomfortable. Others said it could be because there is now concrete everywhere.

The building, water and soil have been damaged to a certain extent.

In the future, it may get hotter and hotter every year, because the greenhouse effect will get worse every year.

In the future, it may get hotter and hotter every year, the global climate has changed, our environment has been greatly damaged, and global warming has become a trend.

In the future, it will not be hotter and hotter year by year, and if it is hotter, there will be problems for people's survival, and the protection of the ecological environment will start from now on.

1. Now that the global temperature is warming, the ozone layer is beginning to thin out, and the greenhouse effect has made the icebergs begin to melt, not to mention the temperature change. The urban heat island effect, the increase in global carbon dioxide levels, leads to an increase in atmospheric temperatures. So, now that the ozone layer is thinning, it is understandable that the temperature is rising.

2. The change of sea level is a continuous upward trend, according to the relevant experts, by the middle of the next century, the sea level may rise by 50cm. If measures are not taken, it will directly lead to the destruction and pollution of freshwater resources. In addition, a large amount of toxic chemical waste and solid waste generated by land-based activity sites are continuously discharged into the ocean; Major oil spills (leaks) in seawater and the destruction of the ecological environment in coastal areas caused by human activities are the main factors leading to the destruction of the seawater ecological environment.

Many friends are curious about why the temperature has become hotter and hotter in the past two years. According to previous data, greenhouse gases.

Concentrations have been increasing at sea level.

It's also on the rise. Then the change of the global climate will naturally affect our country, so judging from the current situation, it is very likely that the next summer will become hotter year by year.

If we only look at this year, this summer's high temperature is due to the high summer pressure in the east and west of our country. It has an amazing performance in explosiveness and stamina. The Iranian high pressure is abnormally strong in the west, heading eastward to northwest China.

and converging with the continental high, exposing the northern region to a strong and stable warm high pressure and sustained high temperatures.

At 8 o'clock on July 26, Beijing time, the 500hpa isobaric surface altitude field, the three major high pressures have been opened **meteorological station.

In addition, the westward airflow is sinking and heating up in the foothills of the Taihang Mountains, which is the driving force behind the extreme heat in Henan and Hebei. According to the China Meteorological Administration.

According to statistics, in June 2022, the national temperature was higher than the same period of the previous year, the highest since 1961.

But have you ever noticed that "this summer is hotter than before", which we seem to say every year?

What you think is an abnormally high temperature is actually a foreshadowing. From 1951 to 2020, the average annual increase rate of land surface temperature in China reached an annual rate, which was significantly higher than the global level in the same period. Especially in the last 20 years, it has been the warmest period since the beginning of the 20th century.

Nine of the 10 hottest years in China since 1901 occurred in the 21st century.

The reason why China has become a "hot high-quality student" is, first of all, that China has a vast territory. The land warming rate is higher than that of the ocean, and the land area is large, which provides important conditions for the significant increase of regional temperature. Among the top three countries by land area, China's latitude is generally lower than that of Russia and Canada, which means that China has access to relatively more heat.

With the dual blessing of both, China's warming rate is far faster than the global average. In addition, China, as the largest developing country in the world, is at the height of its urbanization process, and carbon dioxide.

Massive emissions of greenhouse gases and the urban heat island effect also contribute to climate warming.

The driving force. But it is undeniable that behind the rise in temperatures in China is global warming.

megatrends. Although scientists have repeatedly attributed the process of high temperatures to specific "abnormal atmospheric conditions", what is certain is that changes in the global climate have caused regional atmospheres to mutate and adjust, leading to extreme heat. In 2020, the average global temperature will be above pre-industrial levels.

From 2011 to 2020, it was the hottest decade since 1850.

If global warming rises to 2°C in the next two decades or so, then there should be a once-in-a-millennium heat wave.

May occur every 5 to 10 years.

The concentration of greenhouse gases has been increasing, and the sea level has been rising, so changes in the global climate will naturally affect our country. Judging from the current situation, it is very likely that the next summer will get hotter and hotter every year.

Extreme weather has been on the rise in recent years, and the coverage is expanding. Most of the reasons are due to the destruction of the environment by human beings. It is estimated that these hot days will be the norm.

It depends on the place, and although it is said that global warming is getting hotter every year, it doesn't get hot all of a sudden, but the average temperature rises by a few tenths of a year every year.

It will get hotter and hotter every year in the future.

The high temperature weather in 2022 can be said to be a record-breaking, and many places have successively said that the current high temperature weather has broken through the highest temperature since the establishment of meteorological observation stations, and the temperature in places like Sichuan, Shaanxi, Henan and other places in 2022 even exceeded Turpan in Xinjiang for a time. Such a hot weather is indeed a little frightening.

Under the continuous hot weather, many office workers are mourning. After all, in such high temperatures, daily commuting becomes a big problem. In fact, if you look at the summer temperature over the years, you will find that such a trend is indeed slowly forming.

Last year, the time of hot weather was advanced, and the high temperature in many places also exceeded 43 degrees.

According to the global climate situation published by the World Meteorological Organization, the concentration of greenhouse gases has increased over the years. Sea levels are also rising. Then the change of the global climate will naturally affect our country, so judging from the current situation, it is very likely that the summer in the future will be hotter and hotter every year.

Measures to address warming temperatures

1. Reduce carbon dioxide emissions: improve energy utilization technology and energy efficiency, thereby reducing the use of coal, oil and natural gas, and reducing carbon dioxide emissions. Adopt new energy sources, such as:

Solar, wind, geothermal, ocean, nuclear, hydrogen, etc.; It can also increase the proportion of water energy in conventional energy and indirectly reduce carbon dioxide emissions.

2. Afforestation: Solutions to protect forestsToday's global forests, which depend on tropical rainforests, are being rapidly and rapidly destroyed by humans. The most effective response is to stop this uncontrolled deforestation and to promote forest regeneration through large-scale reforestation.

It may be influenced by the monsoon climate, geography, and the environment in which we live, all of which may contribute to the increase in global temperatures. ：

One. It is closely related to our lives. The economy is developing very rapidly, and now you can see some products of the world's development everywhere, and you can see high-rise buildings everywhere.

The development of science and technology is very rapid, and the technology products that can be seen everywhere are actually consuming the environment brought by nature, such as the cars that are now full of streets, most of which burn gasoline, and gasoline will produce some gases that are not good for the environment after combustion, which may lead to the production of acid rain and the occurrence of global warming. This is one of the reasons for the increase in temperatures, and the temperature in the cities is generally much higher than in the countryside, because the cities are densely populated, the houses are dense, the cars are also very large, and the vegetation is relatively small, which can lead to the increase in the temperature of the urban disturbance.

Two. There is also a certain connection with geographical location. There may also be a certain relationship between the hot weather and the geographical location, for example, the weather in the south of China is generally much higher than that in the north, and there are some coastal areas, which are particularly hot in summer.

In addition, it is also affected by some monsoon climate, the temperature in Chongqing is generally higher than the surrounding environment, and the humidity in this place is relatively large, and the summer is like living on a steamer, and you have to blow the air conditioner and fan every day, if you blow the fan, it is also a warm wind.

In fact, the increase in global temperature is also related to other factors, and this is only part of it.

The continuous increase in global temperature has only been evident since the beginning of the Industrial Revolution. The main reason is the rapid development of the industrial revolution and the rapid progress of science and technology, which has led to a large increase in the use of chemical fuels, and some technological products such as automobiles and airplanes emit a large amount of carbon dioxide, methane, nitrous oxide and other heat-absorbing greenhouse gases into the atmosphere.

The concentration of these greenhouse gases in the atmosphere is getting higher and higher, so that the atmosphere forms a film of greenhouse gases, thus forming the greenhouse effect, the heat of the sun radiates to the ground, and then reflects to the high altitude, these heat can not be dissipated due to the greenhouse effect, making the temperature of the earth higher and higher, resulting in global warming.

Causes of the heat island effect

Mainly because of the large use of cement, asphalt roads, concrete, etc. in the construction of buildings, roads, etc., these materials account for more than 70% of the construction of the city, and these materials are easier to absorb solar radiation, heating up quickly, for example, the same quality of cement warms up 1 degree Celsius, which is much less than the heat radiation required by the soil.

It is precisely because these urban building materials absorb solar radiation vigorously, and then emit it into the air, making the city stuffy, a city is like a super-large solar water heater, absorbing the heat vigorously, do you say the city can not be hot?

In addition to these building materials, factories, cars, air conditioners and so on in the city will release a lot of heat to the outside world, such as in the summer when the weather is too hot, many people have to turn on the air conditioner at home, the air conditioner is turned on, your home may be cool, but the heat is discharged to the outside through the exhaust vent in large quantities, so the outside temperature is higher.

Studies have shown that the hot air discharged from the air conditioners in Xi'an can heat Weiyang Lake into a hot spring within an hour, and the temperature of the lake water will increase by 10 degrees Celsius. The anthropogenic heat emitted by buildings in the Beijing area can increase the temperature by up to a degree Celsius.

1.The earth revolves around the sun.

The Earth has always revolved around the Sun, and the range of its revolution is within the Tropic of Capricorn. As a result, the northern and southern hemispheres have four seasons of spring, summer, autumn and winter. On the summer solstice (June 20 or 21 or 22 in the Gregorian calendar), the sun shines directly to the northernmost point of the Earth (the Tropic of Capricorn).

Our country is in the Northern Hemisphere, so the weather will start to heat up at this time.

2.Influence of the subtropical high.

In the subtropical region of the northern and southern hemispheres, due to the influence of sea and land, the high-pressure belt is often broken into several high-pressure monomers, forming a discontinuous high-pressure belt distributed along the latitudinal circle, which is collectively referred to as the subtropical high.

1) Under the influence of the subtropical high pressure, the air flow sinks and the sunlight shines directly on the earth. In addition, the radiation warming of the ground will gradually reduce the amount of heat dissipated on the surface, and the weather will become hotter.

2) When the tropical high in the sub-cherry excitation cavity controls a certain area for a long time, it often causes drought in the area. Reduced rainfall is also an important factor in the hot weather.

Hope this helps you with the lead shirt.
