Abstract:Based on the modern process research, abundance of climate and environment information were collected, the influence factors from nature and human activities synthesized, and momentous climatic and environmental events, especially calamity climate events by the means of high resolution ice core analysis anatomized. In this paper, the character and mechanism of climatic and environmental evolution, microbe evolvement under the ultra-low temperature, the cause of atmospheric greenhouse concentration variations and its relation with climate change, and the estimate of the effect on environment by human activities are being discussed on the evidences from ice cores recovered in Qinghai-Tibet plateau.
