41.7 ℃, the highest temperature in the single station of the Shandong National Meteorological Observation Station this summer.

This summer, Shandong's friends felt hot, but in fact, from the vertical direction in the province, 41.7 ° C has not been ranked in the top three in the extreme highest temperature in 16 cities in the past 20 years. On July 15, 2002, the highest temperature in Texas reached 42.6 ° C, the highest temperature in Tai'an reached 42.1 ° C, and the highest temperature in Jinan reached 42 ° C.

Putting into the horizontal ratio of the country, under the heat waves, high temperatures above 42 ° C this summer are not uncommon. Judging from the summer of August 23, the monitoring data of the 2418 national meteorological observation stations at 12 noon on August 23 showed that the highest temperature in the top ten of the high temperature list exceeded 43 ° C.

The Sichuan -Chongqing area is undoubtedly the "severe disaster area" that appeared extremely high this year. At 14:58 on August 24th, the county can reach 43.9 ° C, breaking the highest record of the National Meteorological Station of Sichuan Province. At 16:00 that day, this record refreshed again By 44 ° C; on August 18th and 19th, the maximum temperature of the Observation Station of the Chongqing Beiyi National Observation Station reached 45 ° C.

Not only the Sichuan Basin, which was burned at high temperature, continuous high temperature weather also appeared in Jianghan, Jiangnan, Jianghuai and other places. The long duration, wide influence, and significant extremes are the significant features of high temperature events in 2022.

In 1961, there was a complete meteorological observation record. The strongest high temperature process

The Central Meteorological Observatory issued the first high -temperature red warning of this year at 18:00 on August 12. From this day, the highest -level high -temperature warning was issued for 12 days. It will not be slightly fell into a high -temperature orange warning from August 24. People who cannot be in the immersive may not feel what kind of heat is under the red warning. Let's put it this way. Although everyone thinks that Shandong is already hot this year, the highest -level high -temperature warning issued by the Shandong Meteorological Observatory this year is an orange warning Essence

On August 26th, the Central Meteorological Observatory continued to issue high -temperature orange warnings. From July 21st to August 26th, the Central Meteorological Observatory has continuously issued high -temperature warning for 37 days.

According to the monitoring of the National Climate Center, from June 13th to August 24th, the average number of high temperatures in the country was 13.2 days, 6.1 days more than usual. A total of 1,053 national meteorological stations have the highest temperature of the national meteorological station reached the standard of extreme high -temperature events, accounting for 43.5%of the number of nation's total stations. The highest temperature of 365 national meteorological stations in Chongqing, Sichuan, Hebei, and other 24 provinces (cities, districts) has the highest temperature or break through the historical pole.

The duration is long, the scope of influence is wide, and the extremes are significant. In 2022, the comprehensive intensity of the high -temperature heat wave incident has reached the strongest meteorological observation record in 1961.

More and more heat is not an illusion. From 1951 to 2021

This summer is so hot, it can be circulated online. According to the paper published by the Scholars of the Institute of Atmospheric Physics of the Chinese Academy of Sciences in "Nature · Communication" in June 2020, "this year is the coolest year in the next 10 years." For anxiety. On August 22, the Institute of Atmospheric Physics of the Chinese Academy of Sciences opened a rumor on its Sina Weibo that the papers did not involve the temperature prediction of the next 10 years, nor did it be proposed, and it did not support "this year is the coolest year in the next 10 years". Conclusion.

However, everyone's concerns can also be understood, because it seems to be a trend. When it happened, the climate system was unstable.

The "China Climate Change Blue Book (2022)" released by the China Meteorological Administration shows that the global warming trend is still continuing. It is worth noting that China has become a sensitive area for global climate change. China's temperature increase rate is higher than the global average level at the same time, and the average annual precipitation has increased, especially the extreme weather and climate events such as high temperature and precipitation.

From 1951 to 2021, the average annual temperature of the Chinese surface was rising significantly, with a temperature increase rate of 0.26 ° C/10 years. In the past 20 years, it has been the warmest period in China since the beginning of the 20th century; in 2021, the average temperature in China is 0.97 ° C higher than the annual value, the highest value since 1901.

Why are we worried about high temperature?

High temperature has adversely affected human health, agricultural production, and power supply.

Screening of thermal radiation: Thermal radiation disease is the most serious situation in high temperature -related emergencies, that is, severe heat stroke, and once it occurs, the mortality rate is extremely high. The extreme high temperature this year has frequently entered the public vision.

On August 25, the reporter clicked on Weibo topic#8 8#, and found that the number of reads of the topic reached 1.24 billion, the number of discussions was 84,000, and the number of originals was 16,000. In the WeChat index, the popularity of "thermal radiation disease" is also high.

Drought: The Ministry of Water Conservancy held a press conference related to the health harvest of the Yangtze River Basin on August 17, which said that the drought defense situation of the Yangtze River Basin was severe:

Power grid load innovation high: On August 24th, China Energy News issued an exclusive interview with relevant persons in charge of the National Energy Administration. The National Energy Administration stated that due 4 days of innovation high. As of now, 21 provincial power grid loads have reached a record high, and the 5 regional grids except the other five regional power grids except the Northeast have reached a high.

These are just the most intuitive influence of high temperature, and they are still extensive and far -reaching influence on ecology and economy. In addition to worrying, what else can we do?

There are many related analysis for the causes of extreme high temperature this year.

Zhou Bing, chief expert of the National Climate Center Climate Service, said that since June this year, over the subtropical region of the northern hemisphere, the Western Pacific subtropical high -pressure band, the Atlantic high -pressure band, and the Iranian high -voltage belt are evenly enhanced. It makes the hot air stay near the ground, and then the high -temperature heat wave event occurs.

It sounds like a natural phenomenon. As human beings, we seem to be powerless. However, the big background of this extreme weather is global warming, and "global warming in the past 50 years has occurred at an unprecedented speed in the past 2000".

The Special Committee of the United Nations Intergovernmental Climate Change officially released the Sixth Evaluation Report (AR6) on February 28 this year. The impact is increasingly attributed to climate change caused by human activities, especially the increase in frequency and intensity of extreme events, such as the increase in the range of wildfires and excessive deaths caused by heat waves. The report calls for the adopting actions to deal with climate change.

On April 4, 2022, the third working group of the Sixth Evaluation Report of the Intergovernmental Climate Change Special Committee of the United Nations report "Climate Change 2022: Slow Climate Change" was officially released. It is impossible at 1.5 degrees Celsius. The 1.5 Celsius is the standard established by the Paris Agreement in 2015. If the global warming exceeds this limit, it will mean a more serious impact of climate change.

So what should we do? Comprehensive transformation is urgent. The report pointed out that decision makers of government, civil organizations and private sector can give priority to expanding the scale of clean energy; increase innovation to achieve industrial decarbon; encourage green buildings; re -examine urban design, turn to zero -carbon and low -carbon transportation; protect Ecosystems, improve food systems. For ordinary people, they can change their lifestyle, travel or ride bicycles, avoid long -distance flights, adopt more sustainable dietary habits, reduce food waste, and use energy in the building more efficiently.

We have only one earth, and everyone is not bystanders.
