Identifying the cause and mechanism of various global and subcontinental-scale long-term climate changes, we will provide a scientific basis that recent global warming is highly likely due to greenhouse gas emissions associated with human activities. Moreover, we will train general people, including university students, to recognize that remarkable global warming cannot be avoided in the future, unless we immediately take fundamental mitigation and adaptation.

　We analyze various observational and multi-model datasets and will clarify how the Earth's climate can change and how much various climate forcing factors, such as changes in solar irradiance, volcanic eruptions, and human activities, will affect global warming in recent years. Based on the obtained scientific understanding, we will provide the correct knowledge on the global warming to the people lived in Okayama and other parts of Chugoku and Shikoku district.
