As a result, he decided to do something that will help people further understand meteorology and its influence on daily life.

In August, he posted a six-minute video, introducing Climate Change 2021: The Physical Science Basis, an annual report of the UN's Intergovernmental Panel on Climate Change.

Based on his own experiences, Liu says in the post that last year, for him, was a harvest year, which indicates that there was an increase in extreme weather events in China. Many strong tornadoes and some extremely heavy rainfall hit big cities such as Wuhan, Hubei province; Suzhou, Jiangsu province; and Zhengzhou, Henan province.

Last year alone, 42 heavy downpours and 47 strong convective weather events, including tornadoes, were recorded, according to the China Emergency Information website, run by the Ministry of Emergency Management.

At the end of the video, he calls on everyone to take action to restrain climate change and protect our planet.

"Through my videos, I hope more people will learn more about extreme weather events and be prepared before they occur," Liu says.
