Three-dimensional numerical climate models have been used for simulating climatic changes due to an increase of the atmospheric CO_2 concentration (i.e., the greenhouse effect). In spite of quantitative differences between climatic changes simulated with the use of different models, some common changes have been found in the air temperature field when the CO_2 concentration is doubled. The temperature increases in the troposphere but decreases in the stratosphere. The increase in the tropospheric temperature enhances in high latitudes in the winter hemisphere mainly due to the sea-ice area feedback effect. The climate models require to be further improved to evaluate the greenhouse effect more quantitatively. In particular, much yet remains to be done in the treatment of the oceanic general circulation, clouds and ground hydrology.
