Abstract: The annual mean air temperature in China had increased about 068℃ since 1950's due to the contemporary climate changes, such as the sunspot cycles, the movement of the earth and celestial bodies, movement of earth's crust, greenhouse effects, cooling effects of aerosol, the change of global circulation, the change of seawater temperature, monsoon of winter and summer, deforestation, etc. The minimum air temperature in Northern China had increased 024℃. The annual precipitation all over the country was declined by 232mm. The amount of declined precipitation was more in North China than in South China. The simulated results show that the current warm period would last until 2015. The climate would turn into cold period from 2016, and be back to warm period in 2039. In 2020, the whole air temperature in China would increase by 1.68℃. The air temperature in the North-Eastern China would increase by 22℃. The annual precipitation in South China would increase by 28mm, and there would be no change in North China. In 2030, the sea level would elevate 5.3～14.2cm, and the climate would become drier.
