The Chinese Meteorological Administration (CMA) held a press conference on Wednesday in which it rolled out the Blue Book on Climate Change in China 2021. The report shows that between 1961 and 2020, extremely heavy rainfall experienced an increase. progressive and extreme heat episodes increased. significantly in the country since the mid-1990s. Comprehensive climate observations and several key indicators show that global warming is continuing and the risk of experiencing extreme weather and climate events in China is increasing.
The Blue Book provides the latest climate change monitoring information in China and around the world, including data on the atmosphere, hydrosphere, cryosphere, terrestrial biosphere, and determinants of climate change.
According to the Blue Book, China is a sensitive and important area impacted by global climate change with a temperature rise significantly above the global average during the same period.
In 2020, the sea level in China’s coastal areas was 73 mm higher than the 1993-2011 average, the third highest level since 1980. The continuous rise in sea temperature in summer has caused severe coral bleaching in several islands, including Nansha, Xisha, Hainan, Taiwan and Gulf of Beibu.
The Blue Book points out that China’s climate risk index from 1961 to 2020 shows an increasing trend, and in 2020 the number was 10.8, the third highest value in that period.
The Blue Book also shows that the average intensity of typhoons landing in China has increased since the late 1990s. In addition, between 1961 and 2020, the average number of dust days in northern China registered a significant drop. .
As for the climate situation in China this year, Wang Zhihua, spokesperson for the Emergency Disaster Reduction and Civil Service Department of the CMA noted that the average temperature and rainfall in China in July of this years were higher than in previous years and it is expected that climatic conditions will remain active in August.
According to Wang, several tropical cyclones could significantly affect coastal areas in southern and southeastern China in August, and northern areas could face strong convections, such as wind and hail. Heavy rains are also expected across the country.
During the press conference, Jia Xiaolong, deputy director of the National Climate Center, spoke about media concerns about extreme weather conditions around the world, including recent torrential rains in central China’s Henan Province. . He noted that extreme weather events have occurred around the world this summer, including high temperatures in North America and flooding in Europe, which are direct manifestations of the abnormal global atmospheric circulation.
Global warming intensifies the instability of the climate system, which is an important climatic factor for the frequency of extreme weather and climate events, Jia said.
