THE CHALLENGE IN FRONTIER OF THE SOLID-EARTH SCIENCES

Qian Xianglin(Departmen of Geology, Peking University,Beijing,100871)  
The planet Earth is traced in a long history of billions of years from its earlystages to the present conditions of the whole earth system. To understand the nature of itspast behavior in the light of geological history is very helpful for predicting the future.The greenhouse effect is in uncertainty because of the difficulty of how to explain the re-peated alternation of glaciations and interglaciations in the last 1.5 or even 2.4 Ma inQuarternary without man-made emission of carbon or fuel.What is the tendency of the atmosphere temperature the CO_2 or CH_4 superposes. Another example of uncertainty is whether any natural variation of the ozone exists in strato-sphere and its self-recovering effect occurs in this variation. The solid-earth sciencesshould partake the global change as the frontier of the earth sciences in sustainable devel-opment.
