1 Objective

the purpose of this research -- change of the whole earth environment, i.e., composition of climate, the atmosphere, and the ocean, and land changing and going in one, the ecosystem of - sea affecting it mutually -- simulation developing the integrated model of the made earth environment (earth system), and it -- using -- charcoal base -- it is performing global warming prediction including feedback of circulation.

Model simplified based on CO₂ release scenario by human activities in old global warming prediction about the future of the carbon-dioxide (CO₂) concentration in the atmosphere which caused warming It uses, the absorbed amount to the ocean and a terrestrial ecosystem (vegetation and soil) is estimated, and it is air CO₂ concentration. Future prediction was performed first, the result was introduced into the climate model and the simulation of warming and a climatic change has been performed. However, it cannot be said that this is enough. CO₂ increase is warming. Although - climatic change is caused, it is because the feedback effect was not conversely adopted although a climatic change affects CO₂ in the atmosphere concentration. Disassembly of a soil organic matter progresses by warming, the concentration of CO₂ or methane (CH₄) increases into the atmosphere, namely, since positive feedback may act, it is dangerous that this is disregarded.

A carbon cycle process is included in a climate model, and the feedback effect is taken. You have to predict by the put-in model. Moreover, warming and a climatic change are change of an ecosystem. Although it is thought that it causes, it also influences CO₂ and the concentration of CH₄. Furthermore, the troposhere ozone which is another greenhouse gas is also influenced of warming and a climatic change. Then, it is mind about the process of the carbon cycle and atmospheric composition change over the atmosphere, the ocean, and a terrestrial ecosystem. It takes in to a season model and they are structure) and them about (carbon cycle, atmospheric composition, and a climate integrated model. It is necessary to conduct the warming prediction experiments including feedback.
