It has been revealed that the main cause of extreme heavy rainfall in East Asia over the past 60 years is human-induced global warming.
The Korea Advanced Institute of Science and Technology (KAIST) reported that the intensity of heavy rainfall in East Asia has increased by about 17% over the past 60 years, with the main cause being human activities, through an international joint study between the U.S. and Japan by Professor Hyeongjun Kim of the Munsul Graduate School of Future Strategy and Dr. Suyeon Moon of the Institute for Humanities and Social Sciences. It was announced on the 5th that it was proven for the first time in the world using Earth Metaverse technology that global warming is accelerating.
Summer heavy rain has a significant impact on agriculture and industry, and is one of the major threats to human society by causing disasters such as floods and landslides, affecting the local ecosystem.
However, summer heavy rain in East Asia is caused by various processes such as typhoons, extratropical cyclones, and fronts, and research on heavy rain caused by fronts, which account for more than 40% of summer heavy rain, is still insufficient.
In addition, because heavy rain is also influenced by natural fluctuations or coincidences in the climate system, it is not yet known to what extent warming due to human activities affects the intensity of heavy rain caused by fronts.
Accordingly, an international joint research team consisting of eight institutions including Korea, the United States, and Japan, including KAIST, Tokyo University, Tokyo Institute of Technology, Chonnam National University, GIST, and Utah State University, confirmed the intensity of heavy rain caused by weather fronts in East Asia using observation data for the past 60 years and found that southeastern China They found that heavy rain intensity increased by about 17% from coastal areas to the Korean Peninsula and Japan.
In addition, in order to uncover the cause of these changes, we used the Earth Metaverse experiment, which simulated Earth with and without greenhouse gas emissions due to human activities, and found that the intensity of heavy rains was strengthened by about 6% due to greenhouse gas emissions, and that the changes discovered were caused by humans. It was proven for the first time that it cannot be explained without the effect of warming caused by activity.

The results of this study, which was conducted with support from the National Research Foundation of Korea’s Overseas Scientist Attraction Project (BP+) and the Anthropocene Research Center, were published on the 24th of last month in the international academic journal ‘Science Advances’.
