A cold spell in Korea caused the closure of national parks, flight cancellations, and canceled cruise ship voyages. The cold weather reduced pollution but also increased the absorption of carbon dioxide by the East Sea.
Research by professors from Pohang University of Science and Technology and Pusan National University found that the cold Arctic air influenced the East Sea’s ability to absorb carbon dioxide. They studied data from 1992 to 2019 and found that the ocean’s ability to absorb carbon dioxide increased over time, likely due to the circulation patterns influenced by the Arctic cold wave.
Professor Kitack Lee, who led the research, emphasized the importance of understanding the ocean’s capacity to store carbon dioxide. The research was sponsored by the National Research Foundation of Korea and the National Institute of Fisheries Sciences of Korea. This study adds to earlier research showing how the ocean absorbs carbon dioxide, providing potential for carbon storage.
