Change of climate as a consequence of CO2 increase

CO2 economy on the earth's surface is mainly determined by the four large reservoirs atmosphere, ocean, biosphere and rock. Together with solar irradiation and heat transport by oceanic and atmospheric currents this leads to an extremely comlicated system. In recent time work- and time-consuming model calculations were carried out permitting to obtain quantitative results with respect to climate formation, agreeing largely with paleoclimatic observations.
