It is becoming clear that human activities are significantly influencing global climate and ecosystems. The present, when a single species plays such an important role in forming the global environment, may be an unusual epoch from the viewpoint of earth's history. Department of Integrated Climate Change Projection Research works on researches on mechanism for oceanic and atmospheric variations including water and biogeochemical cycles, and assessment of human impacts on those variations. Our main research tools include atmosphere-ocean coupled models dealing with physical variables such as temperature and precipitation, and earth system models incorporating oceanic and terrestrial biogeochemical dynamics important for formation of the global environment. It is hoped that our researches lead to contribution to the society in addition to improved understanding on how the nature works. We also conduct paleoclimate simulations utilizing geological data. Our researches encompassing the past, present, and future of global environment might provide a hint for thinking over the grand question, that is, the meaning of the existence of humankind for earth's history.
