Professor Shojiro Minobu of Faculty of Science Hokkaido University, conducts research on fluctuations and changes in the atmosphere and oceans in Japan and its surrounding areas, as well as around the world. For example, our research subjects include changes in the atmosphere caused by typhoons and bomb cyclones due to global warming, sea level rise, ocean heatwaves, ocean oxygen depletion, and associated changes in the ocean ecosystem. ``Frequent marine heatwaves off the coast of Hokkaido and Tohoku in recent years and the associated increase in yellowtail catches in Hokkaido,'' published in 2021, was reported in newspapers, etc., and was also published in an intergovernmental study on climate change in Japan compiled by the Ministry of the Environment. It is also featured in the Special Report of the Panel Sixth Assessment (IPCC AR6).
