After ending December into January, we also entered the new 2022 year of the Gregorian calendar. In 2021, China's various data have also been settled - according to the monitoring data of the China Meteorological Administration, the average temperature in China in 2021 is 10.7 degrees, which is 1 degree higher than usual, the highest since 1961, that is, the warmest level in 60 years. Among them, 10 provincial capitals/capitals/municipalities such as Shanghai, Hangzhou, Nanjing, Fuzhou, Zhengzhou, Shijiazhuang, Kunming, Nanchang, Yinchuan and Lhasa were the warmest years on record.
For example, in Shanghai, the past 2021 was the hottest year in Shanghai's history, with the average annual temperature of the Xujiahui weather station in downtown Shanghai reaching 18.6 degrees. Xujiahui Station is one of the few meteorological stations in China with an observation history of more than 100 years, and since the meteorological records of Xujiahui Station were recorded in 1873, the temperature data for 2021 has exceeded 2007, which is the hottest year in the 100-year record of the station!

In 2021, although Shanghai has the second lowest temperature of the new century on January 8 - 7.1 degrees, the average temperature in February is rarely higher than 3 degrees, laying the high trend in 2021, the spring temperature continues to be high, the summer temperature returns to normal, but the autumn temperature is higher again, and even the latest winter in history has appeared, and finally the warmest year in history has been reached. The average annual temperature of Xujiahui Station since meteorological records has been 15.8 degrees, which is significantly higher by nearly 3 degrees this year, and the distant eleventh year of Qing Guangxu (1885) is the coldest year recorded at the site, with an average annual temperature of only 14.3 degrees.
Similarly, as one of the few areas in China with a history of meteorological observation for more than a century, Hong Kong also spent the hottest year since meteorological records were recorded in 2021. According to the Hong Kong Observatory's meteorological monitoring data, the average temperature in 2021 is the highest since 1885, while the past 2019-2021 covered the hottest first three years in history. In 2021, Hong Kong's average temperature in March, May and September, the number of hot nights and hot weather days have reached record highs.
Then some netizens have to ask: Is 2021 not the year of "double La Niña"? Double La Niña failed? La Niña is a large-scale cooling of the surface seawater in the tropical Middle East and the Pacific Ocean, but the decline in sea temperature has a remote impact on China's weather, and there are many climatic factors that affect China's temperature and precipitation. Of course, this may also be the result of a warming climate.
