　　At the recent press conference of the joint prevention and control mechanism in the State Council, the spokesperson of the Ministry of Transport predicted the situation of Spring Festival travel rush’s return trip:

　　"Through big data analysis, it is expected that passenger flow will stabilize and pick up around the 16th day of the first lunar month."

　　Although the peak of the Spring Festival return trip this year has been pushed back by the epidemic, with the return to work in various places, at present, large-scale population migration has been restarted.

　　According to big data, the cross-regional population flow in the second half of this year (January 30th to February 18th) in Spring Festival travel rush is about 142 million.

　　At present, in the face of this figure, how is the epidemic prevention and blocking war laid out? How to prevent the epidemic from spreading through public transport? Tan Zhu cooperated with the Big Data Team of Highway Research Institute of the Ministry of Transport and China Unicom Big Data Company, and tried to find some answers by analyzing 5.5 billion original data every day during the whole Spring Festival travel rush period.

　　The return trip this year is unusual.

　　This is the calculation chart of the cross-regional population flow in Spring Festival travel rush in 2020.

　　Generally speaking, the population flow in Spring Festival travel rush should be basically symmetrical, just like a clock.

　　This year, changes have occurred.

　　January 30th to February 18th is the second half of this year in Spring Festival travel rush. During these 20 days, the cross-regional population flow in China was about 142 million people.

　　From February 19th to March 15th, in these 25 days, the cross-regional population flow was about 145 million people.

　　According to big data calculation, compared with the concentration of population movement before the Spring Festival, the return trip was "leveled" and the return trip time was significantly lengthened.

　　What does this trend of population flow mean for the passenger transport system? According to a certain model, we calculated the return passenger volume this year.

　　In the second half of this year (January 30th-February 18th), the passenger traffic in Spring Festival travel rush was around 400 million, down about 70% year-on-year.

　　The peak value of passenger traffic also dropped significantly. Xiao Gaofeng will be formed during the 16th to 23rd of the first month, with an average of 17-23 million person-times per day.

　　According to the forecast, although the return passenger flow is reduced, there will still be about 433 million passengers in China from February 19 to March 15. This also means that in the next month, the return epidemic prevention work cannot be relaxed.

　　Traffic control has achieved initial results.

　　It is undoubtedly good news for epidemic prevention and control that the return passenger traffic has dropped significantly and there is no rush.

　　At present, the railway department has stopped more than 2,900 passenger trains, not only the trains originating from or arriving in Hubei, but also some trains on key lines such as Beijing-Tianjin Intercity, Beijing-Guangzhou, Shanghai-Kunming and Cheng Gui. From January 25 to February 5, the railway department introduced free refund measures five times, and a total of 60.588 million tickets were refunded from January 25 to February 3.

　　Sixteen provinces have completely suspended inter-provincial highway routes.

　　More than 13 million civil aviation refunds have been issued. Except Shennongjia Airport, all airports in Hubei Province have suspended transport flights, and other routes have reduced flights to varying degrees.

　　These measures are coordinated with the policy of extending the Spring Festival holiday and postponing the resumption of work. A set of combination boxing reduces the crowd density and releases more space for the returnees to travel in the wrong peak.

　　This is Tan Zhu’s time distribution based on the information of all trains that COVID-19 patients have taken since January 6th.

　　It can be seen that since January 24, the number of trains and planes with patients has dropped significantly. Especially from February 3rd to 5th, there were 23 passengers, 12 passengers and 7 passengers with fever on the national railway trains, which decreased to single digits in three days. From this point of view, the source of infection that moved some time ago has indeed decreased.

　　However, we are far from taking Spring Festival travel rush’s return trip lightly.

　　Which cities must guard against death?

　　The Standing Committee of the Political Bureau of the Communist Party of China Central Committee meeting of the Communist Party of China held on the 3rd pointed out:

　　"It is necessary to do a good job in the prevention and control of the epidemic situation after the Spring Festival, implement the responsibility of prevention and control of the inflow and outflow of personnel, and strengthen passenger health monitoring and disinfection and ventilation of vehicle stations."

　　Areas where the returning population is concentrated will face greater pressure.

　　According to Ctrip data, Guangzhou-Shenzhen, Harbin-Beijing, Chengdu-Guangzhou and Chengdu-Shanghai are the most popular return routes.

　　This also means that the four cities of North, Guangzhou and Shenzhen will have the most rework crowds and the greatest epidemic prevention pressure. The air ticket data also confirms that the number of passengers sent to four cities in the north, Guangzhou and Shenzhen in the recent stage accounts for more than 36% of the country.

　　In cooperation with the Big Data Team of Highway Research Institute of the Ministry of Transport and China Unicom Big Data Company, we predicted the scale of return population flow in Spring Festival travel rush in 351 cities one by one (until March 15th).

　　The top ten cities are:

　　Guangzhou (11.79 million)

　　Beijing (9.85 million)

　　Zhengzhou (8.36 million)

　　Shanghai (8.17 million)

　　Xi ‘an (7.41 million)　

　　Chengdu (7.37 million)

　　Foshan (6.83 million)　

　　Shenzhen (6.27 million)

　　Suzhou (6.16 million)　

　　Nanjing (6.08 million)

　　In addition, the floating population of Dongguan, Dazhou, Zhoukou, Wuxi, Xuzhou, Bijie, Luzhou, Yibin, Qingdao, Mianyang, Zhongshan, Xiamen and other cities are all above 3 million, which should not be underestimated.

　　CCTV news 1+1 program, National Health Commission expert group member Jiang Rongmeng tip:

　　"There may be an incubation period later. (From January 23rd) 6th is the first incubation period, and then 20th."

　　The new incubation period, coupled with large-scale personnel flow, will become a period of rapid increase of B-type population (people who have contact with patients) and the second-generation B-type population (people infected by B-type) if it is not properly prevented and controlled.

　　Master Tan must remind the above cities here: from now until mid-March, prepare for the worst and do your best.

　　The key lies in implementation

　　In the process of racing against time and fighting against the disease, we must send the returning army safely while resolutely curbing the spread of the epidemic.

　　This is a passenger information registration form that Tan Zhu received on the high-speed train back to Beijing. After arriving in Beijing, this information sheet was collected and kept by the railway department in a unified way, which is convenient for tracking the situation of every passenger.

　　This is just the tip of the joint prevention and control of railways. Master Tan asked the staff of Beijing Bureau, Zhengzhou Bureau and Chengdu Bureau of China Railway to sort out such a schematic diagram of the linkage process of finding suspected cases.

　　From entering and leaving the station for temperature measurement, to setting up observation stations and resident doctors, and then to sending highly suspected patients to the hospital in time, passenger information registration and follow-up investigation … … Such an epidemic prevention process needs the cooperation of railway departments, health and health commission, CDC and other forces, which are interlocking and can’t go wrong.

　　Today, this epidemic prevention process is being strictly implemented by 2775 railway stations across the country. As of 18: 00 on February 5th, there were 403 passenger trains and 489 passengers with fever.

　　Various departments and regions have stepped up measures to try to crack the epidemic pressure brought by the immigrant population.

　　The Ministry of Transport requires that the passenger load factor of national long-distance passenger buses and waterway passenger liners be controlled at 50% during Spring Festival travel rush. The passenger information registration system for road passenger transport has been launched, which is used to track passengers with COVID-19 patients.

　　Multi-class civil aviation has also started the seated mode, simplifying the service procedures, and eating in batches by neighboring seats on long-distance flights.

　　After the transportation system "ensures smooth flow, key points, services and safety", the places where people move in need to take over the baton of epidemic prevention and control.

　　At present, Hangzhou, Harbin, Guangzhou, Shenzhen, Chengdu and other places have begun to implement closed management of communities and units to prevent cross-infection.

　　Beijing and Shanghai have successively issued documents, clarifying that individuals who conceal their contact history will be strictly investigated for legal responsibility according to law and included in the social credit blacklist.

　　"Point-to-point, one-stop" transport of migrant workers back to their posts in all parts of Sichuan, and the government came forward to organize migrant workers to travel by car.

　　It is not easy to return to Spring Festival travel rush, China in 2020. It is a difficult problem for any country in the world to balance the "moving" and "not moving" between cutting off the transmission route of the epidemic and maintaining the normal operation of society.

　　How many points did you get? The key is to look at implementation.

　　A few days ago, I saw a netizen comment, and Tan felt that it was just the atmosphere of returning:

　　Not afraid of ten defenses and nine empty spaces! I hope ten defenses are nine empty!

　　　　　　 CCTV News:Recently, a synthetic brigade of the Army’s 73rd Group moved thousands of miles to the Gobi in the northwest, and organized new and old firepower equipment to conduct live-fire shooting drills around training contents such as command and control, rapid response and precision strike capability, so as to comprehensively test the firepower combat effectiveness of the integration of new and old equipment strike methods.

　　　　　　 In the early morning, the live-fire shooting drill was officially launched in the northwest Gobi. The officers and men quickly maneuvered to the preset position 60 kilometers away by driving the newly distributed firepower equipment. Just after arriving at the position, the fire detachment participating in the drill received the strike instruction, and the command post quickly analyzed and judged the nature of the target returned by the frontier observation, and each fire element completed the shooting preparation at the first time.

　　　　　　 After receiving the shooting instruction, a new anti-tank missile quickly adjusted its shooting angle, and the first missile roared out and hit the target several kilometers away accurately. This type of anti-tank missile is the most advanced anti-tank missile equipment of our army at present. The new equipment can not only strike armored vehicles accurately, but also intercept and damage low-altitude flying targets and fortifications. After the first missile hit the target, a new round of fire attack was launched immediately. The officers and men independently selected the bomb type according to the nature of the target, and all the three missiles launched later hit the target.

　　　　　　 During the drill, the assessment team did not set a plan for the whole process. The guidance and adjustment team took the opportunity to pick up the rockets deployed in another area and transferred the shooting positions, and launched fire suppression on the designated target positions. The rocket launcher used by officers and men is a new type of equipment that has just been installed for less than four months. Compared with the old rocket launcher, the new rocket launcher is more digital, informative and intelligent. The command post only needs to send the shooting data to each artillery terminal, and the gunner can operate the artillery terminal to complete one-button gun adjustment, which saves manpower and greatly improves the shooting speed.

　　　　　　 It is understood that in this exercise, all the newly distributed firepower equipment of this brigade completed the live-fire shooting inspection. In addition, they also assessed the firepower equipment such as howitzers and howitzers. Each fire detachment successively attacked more than ten different targets in four categories at different distances, and launched live-fire shooting drills in a six-hour actual combat environment, effectively testing the operational capabilities such as the integration of new and old equipment, the use of strike means, and the coordination of elements.

1905 movie network news The comedy film starring Chang Yuan, Li Qin, Shen Teng and Qiao Shan will be released nationwide on December 31st, and a national roadshow has been launched. On December 20th, the chief producer Li Yaping, director and starring Chang Yuan, starring Wang Zhi, Miko and other creative artists appeared in Nankai University in Tianjin and several local studios, warmly interacting with fans, sharing wonderful stories behind the scenes, and giving Tianjin special gifts — — Allegro.　

The masters talk about their creative experience　　

Devote oneself to love and tap the inner charm of the role

When he brought Warm Hug home for the first time, Chang Yuan said that he would let the "family" in Tianjin have a look at his first work. When talking about the original intention of creation, Chang Yuan felt a lot. He said: "He (Bao Bao) is an extreme figure, and he is a very happy figure. After digging deep, there are still many things that are empathetic. I want more people to have the opportunity to understand this group of people involved in the film."

Warm Hug is based on the film, but in the eyes of the chief producer Li Yaping, there are great differences between the two works in terms of localized emotions and comedy types, including imaginative pictures in the film. For Chang Yuan, Li Yaping also praised him: "Chang Yuan spent three years rewriting this script. I saw great potential from him and he also gave me great surprises."

Challenging this perfectionist role for the first time, Wang Zhi bluntly said that it was a bit "difficult": "At that time, how to place props should be very neat, including using compasses to wrap jiaozi, what is the diameter of the first layer of leek stuffing, and then what is the diameter of the meat stuffing above, it must be unified." Mike, who plays Bao Bao in the film, is full of milk, which has aroused the audience and won a "warm hug" from small fans.　

The whole process is warm and warm.　

The cinema manager received favorable comments and received enthusiastic response.

After the movie, some viewers said, "This movie has brought me a lot of warmth, a lot of joy and more enlightenment to our lives." The letter written to Xiao Bao Bao in the film moved many viewers, and this is the plot that resonates with Chang Yuan most in the film. Chang Yuan revealed at the scene: "This letter was written at home for three days the day before my son was born. This is a very delicate emotion. Only when you really put yourself in the situation and talk to the protagonist can you know what kind of words and what kind of language can make him grow up and make him bravely love and hug the people around him. "

Previously, at the meeting in Changchun and Shenyang, peers in the industry spoke highly of the film, saying that Warm Hug was "a film with warmth, joy, music, heart, affection and love in 2020". The laughter during the movie was constant, which was comfortable and comforting, and many viewers were moved by the warmth and healing.

Patrol the community, answer questions, report complaints and follow up, help run errands, close windows when it rains, act as a gardener and shovel officer … What does a property manager need to do every day? What can be done to satisfy the owners?

It seems that it is not an easy task to achieve a service that exceeds expectations.

On March 20th, the China Finger Research Institute released the first White Paper on the Development of Property Housekeepers (hereinafter referred to as "White Paper"). This white paper takes Vanke Property Housekeepers as samples, conducts a research on property services, and tells how Vanke Property builds a deeper "spiritual link" with the owners, thus opening the "happiness door" of a beautiful community.

The brand-new transformation of 23 core contacts from "rigid" to "brand-new"

According to the white paper, in order to cover all the living needs of residents in the community, Vanke Property has launched butler service around 23 core contacts in six categories: mobile internet, place service, road to home, leisure stroll, facility landscape and home service, so that the service does not leave any dead ends or blind spots.

For example, in order to ensure that quality supervision does not leave a blind spot, Vanke Property has established a four-guarantee (warranty, security, cleaning and greening) supervision system, which stipulates that the housekeeper should stand on the owner’s point of view when guiding the service quality work, and realize "100% reporting" to ensure rapid response to demands and the processing results meet the owner’s requirements.

Behind the rapid response under high standards, there is also a set of very strict "2341 principles".

That is, respond to the owner within 20 minutes; Solve common problems within 30 minutes and give the owner a reply; Problems that cannot be solved immediately should be solved by coordinating resources within 4 hours; Give a written solution to major problems within 1 working day.

At the same time, Vanke Property has also formed a standardized intelligent work order reporting system by opening up three online platforms: the customer side, the work side and the information management side.

As the core position of property service, the housekeeper will arrange the idle maintenance personnel to take the order at the first time after receiving the maintenance report, from solving the appeal to the later supervision, thus forming a closed loop.

It is worth mentioning that the housekeeper often plays a key role in the work of the four major lines of property. They can not only carry out their work in a planned and decisive way, but also make the messy and complicated work in order. This is inseparable from the talent selection mechanism established by Vanke Property.

It is understood that the White Paper pointed out that Vanke Property established the Butler Studio (formerly known as Butler College) in 2016, and established a step-by-step talent mechanism from selection, training to growth and promotion.

Refine service granularity and inject infinite vitality into the community

How to refine service granularity? Vanke Property has newly formulated internal systems such as "I do something for customers", "Customer Home Temperature Service Manual (1.0)" and "Operation Guide for Business Housekeeper". Through the analysis of the key moments of special people or customers in the space, a series of surprise service lists including empty nest elderly property service guide, vacant house service list, service interruption and extreme weather service list were released.

Nine Personality Traits of "Good Housekeeper" of Vanke Property (Photo courtesy of Vanke Property)

For example, for empty nesters, Vanke Property will record their basic information such as age, gender, and living status, as well as key information such as birthdays, hobbies, and emergency contact information of relatives and friends, and complete customer segmentation. In case of emergency, it can accurately identify the identity of the elderly. They will also teach the elderly one-on-one how to surf the Internet on their mobile phones and hold "sunset red" community activities to help them get out of the loneliness of empty nests.

In addition, Vanke Property also has special services such as escorting children from school and creating a sense of birthday ceremony for the owners, and set up a professional butler team to study a set of surprise service.

Two-way trip behind "something to help the housekeeper" and "little things"

In the white paper, Vanke Property put forward the service slogan of "Help the housekeeper if something happens", and asked the housekeeper to be a smart, eloquent, warm and friendly "Aqingsao", which really solved the life problems of the owners at any time.

In Chongqing Vanke Splendid Riverside, it was particularly vividly interpreted.

With a plant name, a small yellow shirt and a dedicated mobile phone, Vanke Jinxiu Riverside Butler Xu Tiantian (code name "Youdan") started a day’s housekeeping service.

Ms. Zhou, the owner who lives in Hangzhou, will take a pair of children back to Chongqing Jinxiu Riverside for a while every holiday. At this time, the housekeeper "Youdan" became a tourist expert and made a detailed play strategy for Ms. Zhou’s family.

Butler should not only think what users think, but also have "advanced" thinking and service.

On November 8, 2023, also in Jinxiu Riverside, the housekeeper "Yuanbai" received a thank-you letter from the owner. Between the lines, it was full of true feelings.

It turned out that Mr. Huang, the owner, encountered difficulties in dealing with the protective film of cabinets. In the case that the owner offered to pay for the cleaning, the housekeeper "Yuan Bai" volunteered to take this job and used the off-duty time to help Mr. Huang tear off the protective film on the furniture for two consecutive days, which lasted for six hours.

After a long "standby" cleaner, the housekeeper "Yuan Bai" said: "The housekeeper just needs to put the owner’s demands first at all times, so that the service can be seen, known and felt. Doing things for the owners, big or small, is a challenging process, and it is a harvest to solve the small things of the owners as big things. "

In Chongqing, September-October is the rainy season. The housekeeper will pay attention to the weather at any time, and check with colleagues at the security port one by one whether the owner has closed the window. If not, contact the owner and close the window after obtaining the owner’s permission. And it is a small window, Vanke Jinxiu Riverside Butler "Bai Yu" harvested 16 pennants sent by the owner.

"Small probability" events are no longer "rare"

Extreme events are short for extreme weather and climate events, including extreme weather events and extreme climate events. Extreme weather events refer to events with low probability of occurrence, which usually account for only 10% or less of such weather phenomena. Extreme weather events refer to the average state of a large number of extreme weather events in a certain period, and its average state is also extreme relative to the climate average state of such weather phenomena. Extreme events generally have three characteristics: low frequency, high intensity and great social impact. In addition, some weather and climate states or events that are not extreme observed in a small space-time scale are sometimes called extreme events if they occur continuously in time or simultaneously in space.

But with the global warming, this kind of "rarity" is becoming less and less rare.

In the past 2022, frequent extreme events were like "rolling up and down" in a more unstable climate system, which made this "hot kettle" constantly send out worrying alarm sounds. On February 18th, the Atlantic storm "eunice" hit many countries in western Europe and other places, among which the largest gust was about 196 km/h in Needles, Isle of Wight, England, setting a record for the largest gust in English history. From June to August, continuous heavy precipitation caused about one-third of Pakistan’s land to be flooded; At the end of the year, from December 22 to 24, the "epic cold wave" swept across the United States. On the 23rd, the lowest temperature in some parts of the midwest of the United States dropped below -40℃ …

Extreme weather and climate events have also had a great impact on China’s economic and social operation. From May 21st to June 21st, 2022, the dragon boat water, the second strongest in history since 1961, affected the Pearl River Basin. More than 45 rivers exceeded the warning water level, and waterlogging occurred in urban and rural areas. From June 13th to August 30th, a large-scale continuous high-temperature weather process occurred in central and eastern China, which is the longest regional high-temperature weather process in China since 1961 …

According to the World Meteorological Organization, in 2022, weather, hydrology and climate-related disasters, including severe floods, high temperatures and droughts, have affected millions of people and caused economic losses of billions of yuan. Extreme events are widespread, frequent, strong and concurrent, and the "Pandora’s Box" of climate has been opened. How we should act has become an urgent problem to be solved together. (Zhao Xiaoni)

The food security risk is approaching quietly.

Affected by global warming, extreme drought, floods and other disastrous weather frequently occur again, which aggravates the global water shortage and food crisis. Since the middle of the 20th century, about one-third of the runoff of more than 200 major rivers in the world has obviously decreased, and the average yield of wheat and corn has decreased by 1.9% and 1.2% respectively every decade. In 2021, affected by extreme temperatures and floods, the prices of agricultural products such as Brazilian coffee, Belgian potatoes and Canadian yellow peas rose sharply.

The sixth assessment report of IPCC pointed out that more frequent heat waves, droughts and floods have exceeded the tolerance limits of some animals and plants, resulting in a large number of deaths of some trees and corals, especially in Africa, Asia, Central and South America, small islands and the Arctic. Africa is one of the most vulnerable regions in global food security. Since October 2022, the rainfall in the Horn of Africa has been less than 60% of the average level in the same period, and the famine caused by drought has seriously affected the region. In sub-Saharan Africa, drought has greatly reduced food production and triggered a serious food crisis. The decrease in precipitation and the increase in temperature have also aggravated the problem of pests and diseases. Since the beginning of 2020, affected by drought, desert locusts have invaded many parts of the world from Africa to South Asia, and caused irreparable losses to agricultural production in many countries. At the same time, climate change has also led to the expansion of agricultural pests and diseases to higher latitudes and higher altitudes, and the instability of agricultural production has increased. Because of the influence of climate change, the risks faced by the whole production links such as global grain planting, storage, processing and transportation are further increased.

Although global warming may bring some short-term benefits to agricultural production and grain output in some regions, in the long run, extreme weather and climate events caused by climate warming and their impact on agricultural production are more unfavorable and lasting. Therefore, it has become an important issue for all countries to take effective measures on a global scale and actively respond to the food crisis caused by climate warming. (Jane Jufang)

The "number one killer" of biodiversity

Global climate change is one of the main reasons for the damage of biodiversity, including the impact on the geographical distribution pattern of species, genetic diversity, species diversity and ecosystem diversity.

The loss of ecological environment on which biological species or species groups depend is one of the biggest threats to biodiversity, while climate change intensifies the loss, fragmentation and degradation of biological habitats, and even moves to high latitudes and high altitudes, resulting in the narrowing or fragmentation of the distribution areas of some species. For example, the habitat of polar bears has shrunk due to the melting of glaciers, and their predation range has shrunk greatly. The lack of food makes it impossible for female polar bears to accumulate enough fat to produce milk, which seriously threatens their breeding.

At the same time, the population characteristics are also changing, resulting in the decrease of population and the disappearance of endemic species. Under the background of global warming, some turtles and crocodiles may face the risk of extinction. In addition, the diseases caused by climate change have intensified, which once made the amphibian species in North America tend to extinction.

Climate change will lead to changes in the structure, function, development and diversity of ecosystems. The once colorful underwater world is rapidly fading, and the uncontrollable "whitening" is eroding the Great Barrier Reef. On May 10, 2022, the survey results of Australian government agencies showed that 91% of coral reefs in the Great Barrier Reef were albino due to climate warming. The Great Barrier Reef is the largest tropical coral reef system in the world, and the rising sea temperature caused by global warming is accelerating the frequency and scale of coral bleaching. According to a special report of the World Meteorological Organization, 99% of coral reefs in the world are likely to disappear before the end of this century because of climate change.

In addition, climate change also causes the frequency of extreme weather and climate events to increase, such as snowstorms, floods, droughts and other weather, which damages animals and plants and destroys ecosystems. Changes in biodiversity will also adversely affect the climate system, thus further damaging biodiversity. (Liu Qian)

The water cycle is intensifying, and extreme droughts and floods are "double-sided"

Water is closely related to all life on earth. The first Report on the State of Global Water Resources released by the World Meteorological Organization in 2022 shows that there are currently 3.6 billion people in the world who face water shortage for at least one month every year. It is estimated that by 2050, more than 5 billion people in the world will face water shortage.

Under the background of global warming, people can often feel the impact of climate change through hydrological changes, such as more intense droughts, more extreme floods and more irregular seasonal rainfall. The sixth assessment report of IPCC pointed out that with the further global warming, the global water cycle will be further intensified, the seasonal difference of water cycle will increase, the global daily precipitation intensity will increase, and the frequency of extreme precipitation events will increase. Extreme precipitation will increase in almost all areas, and strong precipitation events related to tropical and temperate cyclones will be further enhanced. Generally speaking, global warming will make the wet season wetter and the heavy precipitation events stronger.

The cryosphere is the most sensitive layer to global warming, and the temperature continues to rise, which makes the cryosphere in a state of melting and shrinking. Since the mid-1980s, glaciers have been melting rapidly, and the Arctic sea ice range has been shrinking continuously. Studies show that by 2100, if the global temperature rises by 1.5℃, nearly half of the glaciers will disappear; If calculated according to the relative extreme conditions of 4℃ rise, about 83% of the glaciers in the world will no longer exist by 2100.

At the same time, the melting of glaciers and the expansion of ocean warming will accelerate the rate of sea level rise. In 2021, the global average sea level reached the highest level since satellite observation records. By the year 2100, even if greenhouse gas emissions are greatly reduced and global warming is controlled far below 2℃, the sea level will rise by 30 ~ 60 cm. Sea level rise not only threatens people living in low-lying coastal areas, but also is closely related to ocean acidification, reduced oxygen content in seawater, glacier retreat, shrinking Antarctic sea ice and Greenland ice sheet, which will seriously damage the ecology of the ocean and cryosphere.

Energy system suffers from "indiscriminate attack"

Under the background of climate change, the frequency and intensity of global extreme weather and climate events are increasing, and the energy infrastructure has the characteristics of wide coverage, strong environmental dependence and high exposure. When extreme weather strikes, they will inevitably be affected, and the risk of being threatened by climate is also increasing.

For traditional fossil energy, although its power supply is relatively stable, coal transportation, natural gas pipeline transportation and power station operation will also be affected by extreme weather.

Extreme weather such as torrential rain, tropical cyclone and hail and related secondary disasters often cause direct damage to various energy infrastructures. Rainstorm and the flood disaster caused by it can easily lead to accidents such as pole-down disconnection and transformer short circuit in power grid system. Hurricanes, typhoons and other weather are the main threats to coastal energy infrastructure such as offshore oil and gas platforms and offshore wind turbines.

Photovoltaic power generation and wind power generation, which play the main role in energy transformation, are sensitive to abnormal temperatures. In photovoltaic power generation, extreme low temperature will easily lead to frost heaving of the equipment foundation, while extreme high temperature will reduce the power generation efficiency and service life of the panel. In terms of wind power, water vapor (rain, snow, frost and sea fog, etc.) in low temperature is easy to freeze on turbine blades, which affects the rotation of the wind wheel, while high temperature weather is easy to form a wide range of static wind environment, resulting in windless driving of wind turbines.

In February 2021, the energy supply system in Texas, USA, was completely hit by cold wave and low temperature weather. The low temperature caused the natural gas wellhead to freeze and the gas pipeline to freeze, and the natural gas output once dropped by 50%, resulting in gas-free power generation in the power plant; Insufficient power generation has caused natural gas mining to stop, further aggravating the power shortage. At the same time, wind turbines, which are responsible for 20% of the state’s power generation, are generally covered with ice and forced to stop, and a large number of photovoltaic panels cannot generate electricity due to snow cover …

It can be seen that whether it is fossil energy or renewable energy, the impact of climate change is often an "indiscriminate blow". Therefore, under global warming, human beings need to constantly improve the tolerance, operation and resilience of different energy facilities under extreme conditions in order to keep the bottom line of energy security.

The health impact of underestimated population

The sixth assessment report of the United Nations Intergovernmental Panel on Climate Change (IPCC) points out that in the last 50 years, global warming is happening at an unprecedented speed since 2000, and the threat brought by climate change is intensifying. Studies show that climate change can directly or indirectly have many adverse effects on people’s health through various complicated paths, and no country can be immune to the health effects caused by climate change.

An editorial published by The Lancet in 2022 pointed out that the impact of climate change on health was greatly underestimated. It is understood that more than 5 million deaths every year can be attributed to abnormal high and low temperatures. Among the deaths related to high temperature, 37% can be attributed to climate change caused by human activities. High temperature weather will overload the human body’s own temperature regulation system, which will not only lead to heat-related diseases such as heatstroke and heatstroke, but also increase the risk of morbidity and mortality of cardiovascular and cerebrovascular diseases, respiratory diseases and urinary system diseases.

Climate change leads to a significant increase in the frequency and intensity of extreme weather events such as floods, droughts and typhoons, which will not only cause direct casualties, but also increase the risk of infectious diseases, non-infectious diseases and mental and psychological diseases. For example, extreme heavy rainfall and its flood disaster may change the geographical distribution of vector population, cause casualties and the outbreak of infectious diseases. Studies have shown that the risk of acute influenza, tuberculosis, dengue fever and other infectious diseases has increased significantly after floods. According to the Countdown Report on Health and Climate Change in The Lancet in 2022, compared with 1951-1960, from 2012 to 2021, the length of time suitable for malaria transmission in high altitude areas in America increased by 32.1%, and that in Africa increased by 14.9%. At the same time, under the influence of climate change, the global risk of dengue fever transmission has increased by 12%.

Under the influence of climate change, frequent droughts and changes in precipitation patterns have increased the prevalence and severity of wildfires, which can affect or worsen the condition of patients with respiratory diseases such as asthma through heat injury and smoke exposure. In addition, dust raised by sandstorms can damage human skin and respiratory system, leading to diseases such as tracheitis. (Luo LAN)

　　On August 23rd, local time, leaders of CSTO member states held a video conference to discuss the situation in Afghanistan.

　　At the meeting that day, the leaders of the member States of the Ji ‘an Organization believed that the current development of the situation in Afghanistan has threatened the security of the member States of the organization, and the Ji ‘an Organization should coordinate with the UN Security Council and the G-20 as soon as possible to deal with the situation. The foreign ministers and defense chiefs of member States will formulate joint measures to deal with threats in a timely manner.

　　After the meeting, the Secretary-General of the Ji ‘an Organization, Zas, told the Russian media that it is necessary for the Ji ‘an Organization to coordinate with other international organizations, mainly with the SCO, on the Afghan issue. Zas stressed that the potential civil war in Afghanistan has unpredictable consequences not only for the country’s security, but also for the security of the entire Central Asian region. At the same time, he accused the United States and NATO of withdrawing troops from Afghan territory unprepared, threatening international peace and stability.

　　Ji ‘an Organization was established in May 2002 and evolved from the CIS collective security treaty signed in 1992. At present, there are six member countries: Russia, Belarus, Kazakhstan, Tajikistan, Armenia and Kyrgyzstan. (General Desk reporter Gu Xin)

　　After a brief ceasefire, Georgian troops launched a large-scale attack on South Ossetia from the air and ground on August 8, and announced that they had controlled most of South Ossetia. The conflict has caused 15 deaths. Georgian President Saakashvili made a televised speech to the people on the 8 th, announcing the mobilization of reserve soldiers in Georgia.

　　According to Russian TV reports, Russian troops and tanks entered South Ossetia on the 8th. At the request of Russia, the United Nations Security Council held an emergency meeting on the conflict in South Ossetia, Georgia, late at night on the 7th.

　　Georgia

　　Control most of South Ossetia.

　　Want to control the whole territory in the shortest time

　　At 3: 30 am local time on the 8th, Georgian troops dispatched tanks and infantry to attack the southern suburbs of Tskhinvali, the capital of South Ossetia. The commander of Georgia’s peacekeeping force in South Ossetia said: "We are forced to take action to restore constitutional order in the whole region." Yakobashvili, Minister of State for Georgian Unification Affairs, said: "Georgian troops surrounded Tskhinvali." He said that Georgian government forces have recovered five South Ossetian villages. Yakobashvili also said that Georgia hopes to control the whole territory of South Ossetia in the shortest time. Yakobashvili did not disclose Georgia’s strength in the conflict area of South Ossetia. He said that there were casualties between the warring sides, but the number of injuries and deaths in Georgia was "much less".

　　At present, the central government of Georgia has controlled two-thirds of South Ossetia.

　　National call for reserve personnel

　　Georgian President Saakashvili announced in a televised speech on August 8: "Most of the territory of South Ossetia has been controlled by Georgia …" He said that Georgian troops have occupied the suburbs of Tskhinvali and are currently fighting in Tskhinvali. At the same time, he announced the full mobilization of Georgian troops and the convening of reserve personnel.

　　Georgian government forces and South Ossetian militants clashed in several villages around Tskhinvali, the capital of South Ossetia, on the 7th. Georgian President Saakashvili issued a cease-fire order later on the 7th and announced that South Ossetia would be granted "full autonomy". According to Saakashvili, the Georgian army immediately unilaterally stopped fighting back against South Ossetia. However, shortly after Saakashvili announced the ceasefire, the gunfire around Tskhinvali resumed on the 8 th, and heavy weapons shooting and huge explosions continued to come, and the sky was reflected red.

　　Accusing Russian warplanes of bombing Georgian villages.

　　The Georgian Interior Ministry said that three Russian bombers attacked Georgian villages on the 8th. "Three Russian Su -24 bombers entered Georgian airspace on the 8th. One of the planes dropped two bombs near the Cattell regional police station. " A spokesman for Georgia’s Ministry of Interior said that it was a Georgian village near South Ossetia. A spokesman for the Russian Foreign Ministry said: "This is nonsense, saying that Russian planes flew into Georgia and one of them was shot down." The Russian military also said that the Russian peacekeeping force in Tskhinvali was shelled by Georgian troops and some soldiers were killed.

　　South Ossetia

　　The gunfire went up to the sky, and the capital was cut off from electricity and water.

　　The capital has been cut off from electricity and water.

　　According to South Ossetia, Georgian tank columns and infantry are advancing in the direction of Tskhinvali, several buildings in the city center are burning, and the parliament building has been burned down. The government complex was damaged. Multi-storey residential buildings and other buildings in the city center caught fire, and most of the capital Tskhinvali was destroyed. The city has been cut off from electricity and water, and communication is intermittent. Tskhinvali civilians hid in the basement of their houses to avoid gunfire.

　　The commander of the Russian peacekeeping force in South Ossetia said that Georgia dispatched five Su -25 planes to bomb villages in South Ossetia. The pictures broadcast by Russian TV show that the artillery fire is so fierce that people can hardly walk in Tskhinvali. Russian TV reporters said that at least 15 people were killed in Georgian gunfire.

　　Thousands of volunteers went to South Ossetia.

　　Cocoi, leader of South Ossetia, said on the same day that Georgia had not occupied Tskhinvali. At the same time, many volunteers from Russia and Abkhazia, another part of Georgia, rushed to South Ossetia to participate in the war. Mamu zuroff, leader of the Russian Republic of North Ossetia, said: "Hundreds of volunteers are rushing from North Ossetia to South Ossetia, and it is difficult for us to stop them." Abkhaz leader Sergei BAGAPSH also said: "About 1,000 volunteers are leaving for South Ossetia."

　　More than 2,000 residents of South Ossetia were accepted.

　　Gokoyeva, press director of the Russian Republic of North Ossetia, announced on the 8th that as Tskhinvali, the capital of South Ossetia, was shelled by Georgian armed forces, North Ossetia was ready to receive more than 2,000 residents who voluntarily evacuated there.

　　Gokoyeva said that it is expected that the number of people evacuated from South Ossetia to Russia will increase. North Ossetia has sent transportation to meet these people and arranged accommodation for them.

　　Russia

　　The conflict has escalated into war.

　　The situation in South Ossetia is "unprecedentedly dangerous"

　　This is the most serious conflict in South Ossetia recently. Russian Deputy Foreign Minister grigori Carracin said that Russia considers the current situation in South Ossetia "unprecedented danger". Russian media reported that the conflict between Georgia and South Ossetia has escalated into a war. Senior officials of the Russian Foreign Ministry held an emergency meeting to discuss the situation.

　　The Russian Foreign Ministry issued a statement accusing the Georgian army of "preparing for war". This statement was refuted by the Georgian government. Saakashvili said that the unstable situation in South Ossetia is not in Georgia’s interest. Yuri popov, the Russian special envoy who rushed to South Ossetia, said: "Georgia’s treachery and attack are completely unreasonable, which shows that Georgian leaders have no credibility at all." He said that NATO should reconsider its plan to admit Georgia.

　　Putin said Russia had to retaliate.

　　Russian Prime Minister Vladimir Putin condemned Georgia’s "provocation" on the 8th, saying that Russia would have to retaliate. "Unfortunately, before the opening of the Olympic Games, the Georgian authorities took provocative actions in South Ossetia," said Putin, who came to Beijing to attend the opening ceremony of the 2008 Beijing Olympic Games. "They actually started hostilities with tanks and artillery. This incident is sad, which will trigger retaliatory measures. " Putin said that he discussed the situation in South Ossetia with US President George W. Bush and other leaders.

　　Russian President Dmitry Medvedev presided over an emergency meeting of the National Security Council on the 8th to discuss the situation in South Ossetia. Medvedev promised that Russia will protect the lives of Russian citizens in South Ossetia.

　　According to reports, the South Ossetian authorities announced on the 8 th that a Russian armored force was advancing into Tskhinvali, the capital of Georgia’s South Ossetia Autonomous Prefecture. Georgian President Saakashvili said that about 150 Russian tanks, armored vehicles and other vehicles have entered South Ossetia.

　　Security Council (of the United Nations)

　　Failed to adopt the draft statement drafted by Russia.

　　At the request of Russia, the United Nations Security Council held an emergency meeting on the conflict in South Ossetia, Georgia, late at night on the 7th. In closed consultations that evening, the Security Council discussed a draft statement drafted by Russia. The draft expresses serious concern about the escalation of violent conflicts between Georgian troops and armed men in South Ossetia, and calls on both sides to immediately stop bloody conflicts and give up the use of force.

　　Diplomats attending the meeting said that the United States, Britain, Georgia and some delegates refused to accept the wording of the statement "all parties are required to renounce the use of force." The Security Council finally failed to adopt this draft statement. After closed-door consultations, the Security Council immediately turned to an open meeting from the early morning of the 8th. Russian Permanent Representative to the United Nations Mikhail Churkin said that Russia requested this emergency meeting because of Georgia’s large-scale military action against South Ossetia, which threatened the security of the region. Churkin said that the Security Council must immediately call on both sides to stop hostilities and renounce the use of force.

　　Alasania, Georgia’s Permanent Representative to the United Nations, said that Georgia’s military action was an act of self-defense after repeated provocations, and he accused South Ossetia militants of violating the ceasefire agreement and taking extreme violence. He said that the Georgian government is willing to resume peace talks immediately and called on South Ossetia to stop military operations.

　　Information on the origin of South Ossetia issue

　　South Ossetia is an autonomous prefecture of Georgia, mainly composed of Ossetians, Russians and Georgians. South Ossetia borders Russia’s North Ossetia. Since 1989, South Ossetia has demanded to merge with North Ossetia in Russia. After the disintegration of the Soviet Union, South Ossetia Autonomous Prefecture has been seeking independence and disobeying the jurisdiction of the Georgian central government.

　　South Ossetia passed a referendum in January 1992, demanding the establishment of an independent Republic and the merger with North Ossetia. Therefore, the contradiction between the Georgian central government and the local authorities in South Ossetia has deteriorated sharply, leading to a large-scale armed conflict.

　　The contradiction between the Georgian central government and the local authorities in South Ossetia has also seriously affected the relations between Russia and Georgia. For a long time, due to the close relationship between South Ossetia authorities and Russia, Georgia often accused Russia of secretly supporting South Ossetia.

　　On June 24, 1992, the top leaders of Russia, Georgia, South Ossetia and North Ossetia held talks for the first time on the peaceful settlement of the armed conflict in South Ossetia, and reached an agreement on the realization of a ceasefire, the establishment of a peacekeeping force and a supervision Committee. Subsequently, the two sides of the Georgian-Austrian conflict achieved a ceasefire. According to the agreement, Russia, Georgia, South Ossetia and North Ossetia set up a quadripartite mixed supervision committee to resolve the conflict between Georgia and Austria. The mixed peacekeeping force composed of Russia, Georgia and South Ossetia is responsible for carrying out peacekeeping missions in conflict areas. In November 2006, South Ossetia once again held a referendum on independence, and the overwhelming majority of citizens supported the independence of South Ossetia. But this result has not been recognized by the international community.
