Recent variations of Antarctic temperature, sea ice and ozone

A diagnostic study is made on the characteristics of regional difference of the Antarctic climatic change and the temporal and spatial multiplicity of the climatic change trend by using the temperature data for 1957 1993 from Antarctic and its vicinity, the data of sea ice northern boundary for 1973 1992 and the data of Antarctic total ozone for 1957 1992. The results show that there exists obvious regional difference for Antarctic climatic change, the climatic system is very complicated, and there were spatial and temporal multiplicity for temperature and ozone during the last 35 a and for Antarctic sea ice during the last 20 a. In recent years, the change of Antarctic temperature is not the same as global temperature. This kind of change and difference can not be easily explained by global greenhouse effect.
