The China Meteorological Administration (CMA) held a press conference on Wednesday during which it rolled out the China Climate Change Blue Book 2021. The report shows that between 1961 and 2020, extreme heavy rainfall experiences an increase progressive and extreme heat episodes have 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 drivers of climate change.

According to the Blue Book, China is a sensitive and important area impacted by global climate change with a rise in temperature significantly higher than the global average during the same period.

In 2020, the sea level in China’s coastal areas was 73 mm above the average from 1993 to 2011, the third highest since 1980. The continuous increase in sea temperature in summer caused a severe coral bleaching in several islands including Nansha, Xisha, Hainan, Taiwan and Beibu Gulf.

The Blue Book points out that China’s climate risk index from 1961 to 2020 shows an upward 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 that land in China has increased since the late 1990s. In addition, between 1961 and 2020, the average number of dusty days in northern China has registered a decrease. significant.

Regarding China’s climate situation this year, Wang Zhihua, spokesperson for the CMA’s Emergency Disaster Reduction and Utilities Department, noted that the average temperature and precipitation in China in July of this year were higher than in previous years and that weather conditions are expected to remain active in August.

Wang said several tropical cyclones could significantly affect coastal areas in southern and southeast China in August, and northern regions could face strong convection, such as wind and hail. Heavy rainfall is 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 abnormal global atmospheric circulation.

Global warming intensifies the instability of the climate system, which is an important climatic factor for the frequent occurrence of extreme weather and climate events, Jia said.
