Abstrakt: The destroying of rainforests can warm the climate even more than the doubling of CO2 concentration can do. The temperature close to the surface of the earth can change due to the change of the feedback or the amount of water in the atmosphere, without any forcing or change in the concentration of CO2 as well as other greenhouse gases. This paper derives physically the sensitivity and the response time of the climate due to radiative forcing and a change in feedback. During the last century the temperature increase consisted of change in solar activity (0.47°C), destruction of rainforests (about 0.3°C), increase of the concentrations of the greenhouse gases (about 0.1°C) and increase of aerosols (about -0.06°C). About one half of the temperature increase was anthropogenic. [ABSTRACT FROM AUTHOR]
