China impacted by temperature rise higher than the global average: Govt. Blue Book

China is facing a growing risk of experiencing extreme weather and climate events and a temperature rise higher than the global average as a result of continuing climate warming.


A Blue Book on Climate Change in China 2021 published by China’s China Meteorological Administration (CMA) this week cautioned that between 1961 and 2020, extreme heavy precipitation sees a gradual rise, and since the mid-1990s extreme heat events have increased significantly in the country.

According to the Blue Book, China is a sensitive and significant area impacted by global climate change with a rise of temperature significantly higher than the global average during the same period. According to state media, in 2020, sea level in China’s coastal areas was 73 mm higher than the average from 1993 to 2011, the third-highest since 1980. The continued rise of sea temperature in summer has caused severe coral bleaching in several islands in the disputed South China Sea.

The Blue Book points out that China’s climate risk index from 1961 to 2020 shows a tendency of increase, and in 2020 the number was 10.8, the third-highest value in that period. It also shows that the average intensity of typhoons landing in China has increased since the late 1990s. Additionally, between 1961 and 2020, the average number of dust days in northern China registered a significant decline. China is hit by nine typhoons this year causing widespread devastation. The Blue book comes within weeks of devastating floods in the central Chinese province of Henan, which killed more than 300 people and affected millions more.

Coincidentally, a report from Greenpeace East Asia on Thursday said that scorching temperatures and increasingly severe heatwaves are becoming much more frequent in cities across East Asia. Researchers analyzed temperature data for 57 cities across mainland China, Korea and Japan which showed that hot weather was arriving earlier in the year in more than 80 percent of the cities studied.

The Blue book provides the latest monitoring information on climate change in China and globally, including data on the atmosphere, hydrosphere, cryosphere, terrestrial biosphere and driving factors of climate change. A CMA official, Wang Zhihua noted that average temperature and precipitation in China in July this year were higher than in previous years and it is expected that climate conditions will remain active in August. Several tropical cyclones may significantly affect China’s southern and southeastern coastal areas in August and the northern regions may face strong convective weather, such as wind and hail. High precipitation is also expected across the country, Wang said.
