With the predicted increase in globe temperature, the human face many disasters including the natural ecosystems and the social economy. In the natural ecosystems, there is the melting of the glacier, more rising sea level and so on. In the social economy, there is the production of main crops and animal husbandry, the water supply, the energy resources supply and so on. And there are some relations with the affects. Because there is very difficult to assess all the affects, we only discuss the most important effect in this paper: the melting of the north polar ice cap.
