The weather forecast in Hunan is one year old.
Here, we should correct a wrong view, that is, we should not blindly think that the geographical location of Northeast China is in the north latitude, and the climate is cold all year round. After global warming, the temperature in Northeast China will be just right. This view seems to be correct, but it is actually wrong.
Global warming, what's the climate like in Northeast China? With global warming, the climate in the northeast of China is also undergoing major changes. This change has not become more pleasant as everyone said. However, extreme weather is also prone to occur in Northeast China, especially this year, with global warming and extremely cold weather, there has been a large-scale cooling in Northeast China, with the lowest reaching MINUS 40 degrees.
Global warming and the appearance of extreme weather in Northeast China indicate whether these places in Northeast China are really suitable for human habitation, drawing a big question mark. "It's hot in summer and cold in winter", which are all caused by global warming. The temperature difference between winter and summer reaches nearly 80 degrees Celsius, which is undoubtedly the biggest test for us.
For people who have lived in the northeast, they have long been accustomed to such climatic conditions. Most of the homes are heated and air-conditioned, and most of them are snowy in winter, so there is no special need to go out. This makes people who are used to living in the south very uncomfortable with the living habits and temperature in the northeast.
Is northeast livable? In the case of global warming, the most obvious feeling is the northeast, where extreme weather, high temperature and extreme cold are vividly reflected. Especially this winter, the extremely cold weather in the northeast makes the northeast people feel that the northeast is back. The main reason is that it hasn't snowed so heavily in the northeast for a long time because of the warming climate.
In recent years, the temperature in Northeast China has become higher year by year, which leads to the cold climate that people in Northeast China are used to, and they feel that the climate has changed and it is no longer cold. For them, this environment is no longer a livable environment.
From another scientific point of view, Northeast China belongs to temperate monsoon climate, with four distinct seasons, warm and rainy summer and cold and dry winter. This is a very livable environment. In the northeast, the four seasons are very obvious, and you can enjoy the charming scenery. In many cities in the south, you can't feel the feeling of spring and autumn.
Through scientific analysis, although Northeast China is livable, there are still times of pollution, for example, when PM2.5 and PM 10 exceed the standard in winter, there are still many. Such an environment is very unsuitable for human habitation.
From an economic point of view, it is very good to maintain the current population in Northeast China. Mainly there are very rich land products in Northeast China, such as Daqing Oilfield and Black Land. The most important agricultural products and most of the land in Northeast China are used for farming. If it is transferred to the northeast on a large scale, the national grain will be greatly reduced and the people's food problem will be difficult to maintain.
Generally speaking, living in the northeast is only suitable for people who have lived in the northeast for a long time. For most of us southerners, we are not necessarily used to such living habits and climatic conditions.
The topic of global warming, the influence of glacier melting, was put forward in the 1990s, but it has not been paid attention to and cared about by all countries. The emission of carbon dioxide is increasing year by year, and the global average temperature is also rising. The most obvious experience is the massive melting of glaciers in the North and South Poles.
Many people don't understand the serious impact of glacier melting. The first impact is sea level rise. Although it will not increase much, it will still affect coastal cities in some countries. Second, the ecological circle of animals and plants in the North and South poles has been destroyed, and the living environment is in jeopardy, facing the danger of extinction.
When the food chain is broken, some species will lose their natural enemies, multiply on a large scale, and there will be population flooding. At the same time, when species are extinct, it will also cause the danger of the disappearance of advanced life species. Animals and plants need to recombine into a brand-new ecosystem, but this process is very slow.
The melting of polar glaciers is the biggest test for human beings, which is an ancient virus that has been frozen for many years. The awakening of ancient viruses buried deep underground is a great test of human scientific research at present.
Through the above case analysis, the melting of Antarctic glaciers caused by global warming is a great test for us. Influenced by COVID-19's global influence this year, many countries in the world have no resistance to this kind of risk, and they also put forward the absurd statement of self-immunity, which has caused many countries to get out of hand.
Looking at the most suitable living environment for global warming from another angle, the livable environment is not suitable for everyone, but only for individuals. For people living in the northeast, they are used to the temperate monsoon climate in the northeast, and for people living in Sichuan, it has reached the monsoon climate. People living in Tibet are accustomed to the plateau climate, so the livability varies from person to person.
China is located in five climatic zones: plateau climate, temperate continental climate, temperate monsoon climate, subtropical monsoon climate and tropical monsoon climate, among which subtropical monsoon climate is most suitable for China.
Located in subtropical monsoon climate, Guizhou, Yunnan, Sichuan and other places. Kunming, Yunnan has the reputation of spring-like seasons, with no heat in summer, no severe cold in winter, mild climate and small temperature difference between morning and evening, making it the city with the smallest annual temperature difference in China. Such a city is the most desirable and comfortable city for most people.
There is another city that is also very livable, and that is Guiyang, Guizhou. The average temperature in summer is 23.2 degrees, the highest temperature is between 25 and 28 degrees, and the lowest temperature is between 17-20 degrees. There are few days when the highest temperature is above 30 degrees Celsius, and the ultraviolet intensity is weak. Even if the temperature is 30 degrees Celsius, it will be cool in the morning and evening, far away from industry, and the city pollution is light.
I am the defender of the beautiful ecological environment, and I am glad to answer your question.
From the historical meteorological data, from the end of 19 to the present 100 years, the global average temperature has indeed shown a gradual increase trend, and the warming range is also gradually accelerating. In the past 100 years, the global average temperature has increased by about 1 degree. At the same time, the melting of glaciers at the two poles of the earth has intensified, with the average annual contraction of glacier line 1 m and the average annual rise of sea level of 3 mm, further confirming that global warming has become an established fact.
If the factors such as economy and location are excluded, simply from the perspective of climate and natural environment, with the influence of global warming, Northeast China will indeed become more and more livable.
In terms of temperature, according to the changes in the past 50 years, the temperature in Northeast China is about 2 degrees, the temperature rise in the north is greater than that in the south, and the temperature rise in winter is greater than that in summer. In summer, the temperature in Northeast China is very cool and comfortable, especially in Heilongjiang, central and eastern Jilin and eastern and northeastern Liaoning. The average temperature usually does not exceed 26 degrees Celsius. When there is a high-temperature barbecue mode in the central and southern regions, in addition to the high temperature of about 10 days per year (reaching 30 degrees), the temperature of 20 to 26 degrees is very common, which is also the most comfortable temperature for human body. Many southerners come to the northeast for the summer.
In winter, except in the north, the temperature is still very low, and other areas are not as cold as before. The average number of days that the warming index reaches the standard increases every 10 year10.5 days. In addition, the heating period in the northeast is relatively long, so you will feel warm in the countryside, in a house surrounded by heating, or sitting on a kang.
In terms of rainfall, due to the temperate continental climate in Northeast China, there is more rainfall in summer and less rainfall in winter. With the warming of the temperature, the biosphere, which is greatly affected by the low temperature, becomes active, the biomass also increases, the regional vegetation coverage also shows an upward trend, and the ecosystem as a whole develops in a virtuous circle, thus playing an important role in promoting the supplement and balance of water vapor. In recent years, the drought and lack of rain in winter in northeast China have gradually decreased; Although the rainfall is heavy and concentrated in summer, there are few large-scale floods, which are not easily affected by typhoons (even if there is a typhoon, it is a tropical cyclone that has subsided), and the rainfall is moderate and stable.
In addition, most areas in Northeast China are not located at the boundary of the earth plate, and earthquakes, volcanoes, tsunamis and other disasters rarely occur. The geological and natural environment here has saved many unnecessary troubles and troubles for residents.
According to whether an area is livable or not, the standard of measurement may vary from person to person, and of course it will also include comprehensive indicators in all aspects. These are just my views from the perspective of climate change. Please pay attention to the comments if you are interested. Thank you!
Don't ask this question, it will definitely become more and more livable. In 2030, it will surpass most southern regions and North China. The conclusive evidence is as follows:
1. According to the United Nations climate report, the livable places in Siberia, Russia will double in 2030, and Russia will be the first country to benefit from global warming, followed by Canada, the United States and parts of China, with Alaska in the United States as the main beneficiary and northern Hebei in China as the main beneficiary. The failure of Russia, the United States and Arctic stakeholders to implement the Paris Climate Contract is proof that the United States has directly withdrawn from the treaty, because warming is beneficial to these countries.
The core of this paragraph: the United States is mercenary and egoistic, and the United States has withdrawn from the Paris Treaty and supported global warming!
2. According to the Swedish government's climate report, the top ten uninhabitable cities in 2030 are basically coastal areas. For example, the first one is actually Singapore, a livable city today. The background for the United States to buy Greenland in Denmark is that Greenland melts 1 10 tons of glaciers every day, and it will be in 2030 at the earliest. Nowadays, the melting of polar glaciers is unstoppable.
This core: the melting of glaciers is unstoppable, the rainfall moves northward, the rainstorm and typhoon become more violent, the north becomes a humid area, and gradually moves to the tropical rain forest area in the humid area of the south.
The temperature rises every year, not to mention the temperature rises in all parts of China. Let's take a look at the high temperature records in Europe and Australia. The evidence is directly based on real money. Western Europe has the lowest air conditioning installation rate in the world. Since the new century, the speed of installing air conditioners in summer in Western Europe has increased by more than 10% annually. Europeans don't like air conditioning, so they have to do something against their will, because air conditioning has been installed in summer when it is hot.
This core: global high temperature record, Europeans crazy air conditioning in summer.
4. Amazon forest fire, Russian forest fire, American forest fire, China northeast Yunnan Sichuan forest fire, African grassland fire, global warming is unstoppable!
5. According to the data of China Meteorological Bureau and China Meteorological Network, the high-temperature weather over 30 in summer in Northeast China and other places is still the least in China. These meteorological monitoring can be found not only in the local weather forecast, but also in China Meteorological Network and various weather apps, and it is still cool in summer in Northeast China and other regions.
6. Here comes the key.
According to the authoritative data of the Japanese Ministry of Health and Welfare (equivalent to the Ministry of Health of China) in the summer of 20 19, from July 29th to August 5th, 20 19, 54 people died of heatstroke in Japan, among which more than 30 people were over 60 years old, and China will be aging in 2026, and the elderly will be more afraid of heat. In 20 18, the winter temperature in Japan is always low. According to authoritative data released by CCRC Sun City, the elderly who died of high temperature in summer are 30% higher than those who died of low temperature in winter. The area with the largest number of high temperature deaths in Japan is within 35 north latitude.
In 2005, more than 200 people died of high temperature in France, while only 50 people died of low temperature in winter in western Europe in 2005. So is China.
Global warming makes heat waves more terrible, and heat waves will kill more people. It has become an established fact that several provinces such as the cool northeast are livable.
