On February 6, the China Meteorological Administration held a press conference to officially release the 2022 China Climate Bulletin. The report was completed by the National Climate Center of the China Meteorological Administration, which comprehensively analyzed China’s basic climate profile, climate system monitoring status, and major meteorological disasters and extreme weather and climate events in 2022, and comprehensively assessed the impact of climate on industries. , the environment, and human health. . In addition, relevant experts have also made research and opinions on this year’s climate trend and future climate change issues and have made detailed interpretations.

The National Climate Center’s preliminary research and ruling:The overall deviation of this year’s national annual climate scene
At the press conference, Jia Xiaolong, deputy director of the National Climate Center, said that the current global warming is accelerating, and the impact of climate change on my country is very far-reaching. Climate change affects on the climate system and becomes more unstable. In recent years, extreme weather and climate events in my country have also shown the characteristics of high frequency, wide range of influence, and strong disaster.
According to Jia Xiaolong, regarding the country’s overall climate situation this year, the preliminary research and opinion of the National Climate Center believes that the overall climate situation in the country this year is generally biased, and extreme weather and climate events still show a trend frequent and strong event.
In response to this year’s climate situation, the National Climate Center suggested that the southern region of my country should focus on preventing continuous high temperature weather in the summer in order to ensure energy supply during peak summer; coastal areas should also focus on strengthening typhoon defences; northern regions should focus on preventing heavy rains, floods and other Secondary disasters such as urban waterlogging caused by urban flooding; the western region should improve the prevention of geological disasters caused by heavy rain and other risks.
Song Shanyun, spokesman and director of the office of the China Meteorological Administration, said that the National Climate Center presents seasonal and annual forecasts every month, especially seasonal changes, and also releases them to the public. Regarding the forecasts for the whole year this year, it is usual to organize relevant agencies to hold consultations in March every year to make detailed forecasts and forecasts for the whole flood season.

“Low probability high impact” events will be more likely to occur
Jia Xiaolong mentioned in the press conference that according to the climate change forecast, climate change will continue to exist in my country in the future.
For example, he said, in the future, the average temperature in different regions of my country will still show an increasing trend; extreme weather and climate events will become more frequent and more severe, and extreme high temperature events will be more frequent and larger. serious in the future, and the higher the emission scenario, the faster the growth rate, the stronger the intensity, the greater the risk.
In the central and eastern regions of my country, around 2035, the extreme high temperature event in summer similar to 2013 may become two years. By the end of this century, the risk of high temperature events will increase to dozens of times the current one. In the future, the increase in extreme precipitation in my country will also be greater than the average precipitation, and the variability will increase, and the precipitation will become more extreme.
In the future, China’s average compact rainfall period will also change from the current 50-year event to a 20-year event. Extreme drought events will go from once in 50 years now to once in 32 years. “This shows that our country will still be seriously affected by climate change in the future,” he said.
In addition, the likelihood and risk of compound extreme events will continue to increase. Jia Xiaolong said that, in general, due to the impact of climate change, “high-impact-low-probability” events will be more likely to occur, thereby increasing the challenge of preventing extreme climate risks.

Advocating individuals to change to green consumption patterns
“Individuals not only contribute to greenhouse gas emissions, but are also victims of the increase in extreme weather and climate events under climate change.” Jia Xiaolong said that it is necessary to encourage individuals to turn to green consumption patterns in terms of the basic necessities of life, food, housing and transportation, and to reduce greenhouse gas emissions as much as possible.
He believes that, from a government level, the Chinese government has been strengthening disaster prevention and reduction, emergency management and other aspects of building capacity to deal with climate change. From the public’s point of view, it is also necessary to improve their own awareness of preventing and mitigating disasters and responding to climate change.
Jia Xiaolong pointed out that special attention should be paid to improve the coverage of meteorological disasters, for example, the residents of the northern regions also need to understand some common sense of rainstorm disasters compared to sooner.
He suggested that everyone should understand the meaning of the weather disaster warning information published by the government, including what kind of response measures should be taken for different warning information, and the distribution information of nearby disaster shelters. At the same time, strengthen awareness of disaster and risk prevention in work and everyday life, such as actively avoiding heat in high temperature weather, and reducing going out in typhoon weather.
